  2. I took my wife to visit her mother in one of the hospitals in Nottingham. We travelled from South Wales. She could only have one visitor. I went and sat in the cafeteria. I was the only Caucasian there. I sat there for about an hour and a half. People came and went. Everyone who appeared was of non-European origin. All the visitors. All the staff. All the patients. I was shocked. I could have been anywhere but Britain. It really changed my view of what's happening in this country. In fact I now understand it has already happened.

  3. The AMOC tipping point is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? These numerical models produce ocean circulations that are far from what we actually observe. These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents. The most recent research into the AMOC confirms it is not weakening. From a 2024 paper by Terhaar et al published in Nature Communications "Based on the here identified relationship and observation-based estimates of the past air-sea heatflux in the North Atlantic from reanalysis products, the decadal averaged AMOC at 26.5°N has not weakened from 1963 to 2017". So not even close to a tipping point or collapse. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures -Rahmstorf must be gutted - when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  8. @BonnieShadow33    Hmm. I don't really know how to answer that. Have you read or understood what I've written? The first part of my comment was solely with regard to velocity of AMOC. After all this is a current we are referring to, a flow of water. The observational data shows no reduction in the AMOC. None. The reason in the latter part of my comment I included reference to sea surface temperatures is that this is used as a proxy in this video and elsewhere to show that the AMOC is declining, again the actual temperature data does not support that conclusion. The data on the actual flow of the AMOC that I report is basin-wide. From surface to abyssal plain. From the New World to the Old World. It shows the AMOC is not declining.

  9. If you took away El Niño and Tonga (both natural events) there would be nothing to see. Sea surface temperatures were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two.

  10. There is no climate crisis. The Earth was warmer in the recent and distant past. It has warmed faster in the past. I thought you leaf-peepers who have looked forward to a little warmth living that far north.

  11. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.

  12. Channel 4 propaganda. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This is decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

  14. There is no upward trend in temperature anomalies for summer 2023 according to NOAA USCRN including July. In fact there is no upward trend in the data at all (2005-present). Global Temperature anomaly for July, 2023 = +0.64°C. Global Temperature anomaly for April 1998 +0.62°C Global Temperature anomaly for February 2016 = +0.70°C. (UAH v6)

  15. Couldn't you just tell us about post K-T boundary rather that nonsense it about modern climate change. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  17. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! As an example of good news, Climate Change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022).

  21. It's so easy to look up data for Sicily, and show rainfall has increased. The trend has increased from 402mm in 1979 to 519mm in 2023 (mean annual precipitation ERA5 ECMWF). So it has increased by more than ¼. Summer drought is a perfectly normal aspect of Sicily's Mediterranean climate. The main problem, as touched upon in the video, is water loss through poor infrastructure maintenance. No doubt this exasperated by endemic corruption on the island. The people on Sicily are suffering not from a lack of rainfall, but a lack of good governance. This Euronews item insults its viewers intelligence.

  22. Climate change is not "turbocharging weather events". The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  23. If you were to stand on a seashore at the high water mark for the rest of the century, you would find your feet and ankles wet by 2100. So the answer to the question is we walk away...very, very slowly.

  24. More Channel 4 propaganda. Antarctic ice sheet mass loss is about 90 Gt/yr (Otosaka et al, 2023). It's total mass is 24 million Gt, so it loses less than 0.0004% of its mass annually. It contributes 0.36mm to sea-level rise per year (that's pitiful). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. The ice is here to stay.

  25. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations.

  27. "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.

  28. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  30. Heat waves have not been increasing in intensity or frequency in the United States, which has by far the best meteorological data both spatially and temporally. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. The percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) was at a record low (1895-2023) of 51% in 2023. The record high was 1931 at 93%. The trend has been consistently downwards since the thirties. The climate crisis was 90 years ago. You missed it.

  32. What has happened to people is terrible but this is another BBC spin piece. None of the locations in Greece on the BBC weather app had temperatures in the 40s. Most were in the low 30s. More BBC propaganda. There is nothing unusual about the fire season in Europe. Weekly burn area is way below average. Cumulative burn area is average. Weekly Number of fires are below average. Cumulative number of fires are bang in the middle of the normal range. The same is true for Greece, and the fires at present are a tiny fraction of the maximum recorded (EFFIS). There's no trend for wildfires in Greece. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no objective observational evidence that we are in a global climate crisis. None.

  33. How about the truth? The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23. Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Zhang (2021) shows there is no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  36. Weather events are not climate. The severity of individual weather events cannot be attributed to factors implicated in man-made climate change. Global burned area has decreased by one quarter this century! For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). There is no climate crisis...there isn't even any evidence for it.

  38. This video is Propaganda. There is nothing unusual about the fire season in Europe. Weekly burn area is way below average. Cumulative burn area is average. Weekly Number of fires are below. Cumulative number of fires are bang in the middle of the normal range. The same is true for Greece, and the fires at present are a tiny fraction of the maximum recorded (EFFIS). There is no climate crisis.

  41. There is nothing unusual about the fire season in Europe. There's no trend for wildfires in Greece. By far the largest number of fires and the greatest burn area occurred back in 2007. If you're worried about Greece, don't. Can I recommend “In Search of Climate Crisis in Greece Using Hydrological Data” (Koutsoyiannis et al, 2023)? It shows since records began in the mid-nineteenth century, there is no long term climate variability. Apart from it being slightly wetter 1990-2020 than 1960-1990.

  43. Since 1900 the global temperature has increased by 1.3°C. In that time humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis.

  44. Britain has some of the best and longest tide gauge data. UK-average value for the long term climate change component of MSL (mean sea level)change is estimated from a comparison of tide gauge and geological rates at a number of UK sites. This average long term trend is estimated as 1.4 ± 0.2 mm yr−1 (NTSLF). That's 108mm (just over 4 inches) extra sea level rise by the end of the century. That's an accounting error. And it's not accelerating. Reviews of global tide gauge data show sea-level rise is linear and very slow around 3mm per year. There is no correlation between sea level change and the change in concentration of carbon dioxide in the atmosphere. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm /yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr; Newlyn, UK 1.94mm/yr. Jevrejeva, et al (2014) estimated 2 mm/year (± 0.3), and Church and White (2006) estimated 1.7mm/year (± 0.3). So that's a total rise of between 126 and 151mm (less than 6 inches) from 2024 to the end of the century. A paper from Frederikse et al (2018) shows a global trend of 1.5 ± 0.2 mm yr−1 over 1958–2014. That's 6cm by 2050, and 30cm by 2100. Or try PSMSL data: Kwajalein (Marshall Islands) 1.95mm/yr; Maldives (Indian Ocean) 3.21mm/yr; Lautoka (Fiji Islands, Pacific Ocean) 3.50mm/yr; Port Elisabeth (South Africa) 2.34mm/yr. If one prefers satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. None of this data shows any relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  46. When it comes to tipping points this is what the IPCC (Special Report on implications of 1.5C or more warming, Chapter 3) says:“there is little evidence for a tipping point in the transition from perennial to seasonal ice cover. No evidence has been found for irreversibility or tipping points, suggesting that year-round sea ice will return given a suitable climate”. The IPCC also do not believe the melting of the arctic permafrost will cause a tipping point in the release of warming methane gas “the carbon released to the atmosphere from thawing permafrost is projected to be restricted to 0.09–0.19 Gt C yr–1 at 2°C of global warming and to 0.08–0.16 Gt C yr–1 at 1.5°C, which does not indicate a tipping point”. The Earth's climate is a multi input thermodynamic system and will conform to Le Chatelier's Principle.

  51. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe. Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice - that can be used as a resting/hunting platform for seals and polar bears - hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. "Greenland ice sheet mass balance from 1840 through next week." (Mankoff et al., 2021). If you examine Fig.2 on page 5, you will see there would be no correlation with the exponential increase in the concentration of carbon dioxide (280ppm to 420ppm) and the change in the annual Mass Balance Sum shown in the paper. Indeed there have been periods of increasing mass of the Greenland ice cap in the 1940's, 70's, 80's and 90's. (Remember CO2 was rising all the time.) More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere (14% of total human emissions). The average annual loss is 0.005% of the total mass. That's neglible. Come back in 20,000 years. There's no "death spiral" in the region as some people have reported. In fact, there is, I think, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  52. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth.

  53. This poor young man. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.
    7
  54. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 908 known lost species for 2.1 million known species in 500 years (IUCN Red List), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). Take bird species: 11,195 have been counted (not estimated). All of these have been assessed by the IUCN. They catalogued 4 bird species became extinct over the course of 28 years between 1988 and 2016. That's 1.4 per decade or an annual extinction rate of 0.001%. Also the proportion of species assessed as threatened by the IUCN has declined rapidly over time, from 65% in 2000 (11,000 out of 17,000) to 28% in 2024 (46,000 out of 166,000). This increasingly positive outcome of their species assessments is only accelerating as time passes. Using IUCN data on assessed species- Amphibian species extinct 0.009% per decade. Mammals 0.029% per decade. Reptiles 0.006% per decade. Fish 0.006% per decade. Insects 0.009% per decade. There is no climate crisis.

  55. Nonsense. Please be aware that the IPCC's (Scenario A) modelled predictions are junk. Back in 1990 they predicted a warming of 0.30-0.34°C per decade. Of course we've only had 0.13°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it! But there is still no crisis just an unexciting set of observations. All the climate models run too hot, 100% of them.

  56. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades.

  58. Channel 4 propaganda. Whatever you do, don't mention extreme cold arrived abnormally early in Antarctica, with temperatures dropping to below -75°C from the beginning of May (2023). This marked a new record for the early winter. Checking the satellite data for today (9th August, 2023), the majority of Antarctica is in a cold anomaly with some areas more than 30°C below the normal temperature for this time of year. But don't report or mention that it's bad for the Quasi-Marxist Slow Mass Death Cult Party. The Party told you to reject the evidence of your eyes and ears. It was their final, most essential command.

  59. Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US so far in 2023 including Maui is 3rd lowest on record. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website).

  61. @komousch  You should read chapter 12. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  62. It's so easy to look up data for Sicily, and show rainfall has increased. The trend has increased from 402mm in 1979 to 519mm in 2023 (mean annual precipitation ERA5 ECMWF). So it has increased by more than ¼. Drought is a perfectly normal aspect of Sicily's Mediterranean climate. The main problem is water loss through poor infrastructure maintenance. No doubt this is exasperated by endemic corruption on the island. The people on Sicily are suffering not from a lack of rainfall, but a lack of good governance.

  65. Tide gauge data for Takoradi, Ghana shows sea-level rising at 3.3mm per year. That's very small and very average for the globe. Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  66. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

"There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  68. It is not "all over Europe", northern Europe and western Russia are in a cold weather anomaly i.e. it is colder than the average. No temperature records have been broken in Europe. Rome was supposed to have broken its, but it wasn't as hot as in 1841. Greece is nowhere near its record of 48°C set way back in 1977. It was hotter 50 years ago! There is nothing unusual about the fire season in Europe. Weekly burn area is way below average. Cumulative burn area is average. Weekly Number of fires are below average. Cumulative number of fires are bang in the middle of the normal range. The same is true for Greece, and the fires at present are a tiny fraction of the maximum recorded (EFFIS). There's no trend for wildfires in Greece. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no objective observational evidence that we are in a global climate crisis.

  70. @Burl-tw1yu  America has by far the best instrumental data, and it shows overall the South East cooled in the last 120 years. Though that sentence doesn't do justice to the climate's variability. Data from NOAA (2021) shows uneven warming in the twentieth century focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West US showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day.

  75. 1:45 Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). A study by Venter et al (2018) found the Sahara desert had shrunk by 8% over the previous three decades. The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Increased CO2 causes this in two ways: it has a direct fertilising effect (the CFE), and it increases drought tolerance by reducing stomata. This greening of the Earth due to CO2 is now "an indisputable fact" (Chen et al, 2024). In fact, 55.15% of those areas greening have been doing so at an accelerated rate since 2001. Since the start of the Industrial Revolution the Earth's primary productivity has increased by more than 30% (Campbell et al, 2017 and Haverd et al, 2020). Zhu, Piao, & Myneni, 2016 calculate that 70% of Earth’s global greening in the modern period is due to CO2 and only about 13% is due to fertilizer and land use changes by humans. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 908 known lost species for 2.1 million known species in 500 years (IUCN Red List), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). Take bird species: 11,195 have been counted (not estimated). All of these have been assessed by the IUCN. They catalogued 4 bird species became extinct over the course of 28 years between 1988 and 2016. That's 1.4 per decade or an annual extinction rate of 0.001%. Also the proportion of species assessed as threatened by the IUCN has declined rapidly over time, from 65% in 2000 (11,000 out of 17,000) to 28% in 2024 (46,000 out of 166,000). This increasingly positive outcome of their species assessments is only accelerating as time passes. Using IUCN data on assessed species- Amphibian species extinct 0.009% per decade. Mammals 0.029% per decade. Reptiles 0.006% per decade. Fish 0.006% per decade. Insects 0.009% per decade.

  76. The Arctic is not warming. The Arctic minimum summer sea ice trend is zero for the past 18 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 2024 4.28 Plot the trend line for this data and it will be flat. ZERO net change in 18 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). They also noted "the Arctic temperature was higher in the 1930s–40s than in recent decades, and hence a trend calculated for the period 1920 to the present actually shows cooling." Zhang (2021) showed there was no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Including more recent satellite data from Cryosat-2 (2010-2023)reveals the Arctic ice volume minimum (Oct-Nov) is increasing at 56km³/yr (Kacimi and Kwok, 2024). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  78. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! As an example of good news, Climate Change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022).

  79. Vanuatu has an annual sea-level rise averaging 3mm a year, probably since the end of the ice age. That's the same as everywhere else as measured by tide gauges, so stand on a beach ⛱️ for a century and your ankles might get wet. The actual sea-level anomaly for Vanuatu has been on a declining trend since 2012. In fact the sea level change in a single year (60mm up and down) is 20 to 30 times greater than the trend. It's typhoons that they need to worry about, and fortunately, they've been decreasing for over 7 decades (thanks global warming 👍). The truth is Atolls in the Pacific nations, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8% in size. But the truth isn't scary or exciting...and there's no money in it.

  80. Another artless piece of propaganda from the BBC. As of Sunday 23rd July the Eastern US (except Florida) is in a cold anomaly. I.e. it is colder than average for July. Looking across the Northern Hemisphere the following are also large anomalous cold areas: Northern Europe, Western Russia, Mongolia, Manchuria, and Tibet. This is all weather, not catastrophic man-made climate change. No temperature records have been broken in Europe. Rome was supposed to have broken its, but it wasn't as hot as in 1841. Greece is nowhere near its record of 48°C set way back in 1977. As the report admits it was hotter 50 years ago! There is nothing unusual about the fire season in Europe. Weekly burn area is way below average. Cumulative burn area is average. Weekly Number of fires are below average. Cumulative number of fires are bang in the middle of the normal range. The same is true for Greece, and the fires at present are a tiny fraction of the maximum recorded (EFFIS). There's no trend for wildfires in Greece. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). So Antarctica isn't melting. Then there's the breathless gibberish about Phoenix. Phoenix was incorporated in 1881, NOAA only has continuous data from around 1940. So recorded history for Phoenix in this instance is about 80 years (not that long climatically) and the record for 1930s (when heatwaves were much worse) is mostly incomplete. Also Phoenix's population has expanded exponentially in that time from a few tens of thousands to a few million. This has dramatically increased the Urban Heat Island effect resulting in temperatures 10°F (5°C) higher during the day (Scientific American, 2019). This alone explains the record high temperatures. As I'm sure everyone is aware, Phoenix is in the Sonoran desert, which is characterised by long summers and extremely high temperatures. And that's exactly what's happening. There's nothing unusual or unexpected here. Then tag the floods in: the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. The news story is purposely catatrophising the weather to unnecessarily scare people into changing their way of life. There is no global climate crisis. This is an appalling piece of journalism by the BBC.

  82. There is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling with little change in trend around the Equator (NOAA-STARv5 TLT & TMT 1979-2023). Overall the Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade.

  83. Data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2023, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. How inconvenient!

  84. I had a disconcerting experience teaching in a state school last year. It was a year group assembly. The deputy head teacher started by apologising for not having originally been a true believer, then he instructed everyone to raise their arm in salute, and recite an oath in praise of transgenderism. Other teachers went up and down the aisles making sure everyone had their hands raised and were reciting the oath. It was like watching a mini Nuremburg rally. This process was repeated with all the year groups throughout the school. Printed versions of the oaths were put up on display in every single classroom. Pure propaganda and indoctrination.

  86. Dangerous and pointless. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  88. @darrenb3830  Quotes from IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" That's between 60°N and 60°S, so pretty much where everyone lives.

  90. 2:05 Thermometers, after a fashion, have been in use for centuries. That does not mean, however, that they have been used consistently and repeatedly everywhere for centuries. During the latter half of the nineteenth century reliable records are only really available from parts of Europe, USA and eastern Australia, with a very small number of reliable stations outside of that. Even before 1950 there are essentially no GHCN-Daily stations in South America, India, S. E. Asia, China, Africa, or around the Poles.

  91. ​@volkerengels5298 It's so easy to look up data for Sicily, and show rainfall has increased. The trend has increased from 402mm in 1979 to 519mm in 2023 (mean annual precipitation ERA5 ECMWF). So it has increased by more than ¼. Drought is a perfectly normal aspect of Sicily's Mediterranean climate. The main problem is water loss through poor infrastructure maintenance. No doubt this is exasperated by endemic corruption on the island. The people on Sicily are suffering not from a lack of rainfall, but a lack of good governance. This ITV news item insults its viewers intelligence.

  92. @scottekoontz  Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since at least 2005. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (Kunkel, 2022, EPA). The all-time high temperature records set in most states occurred in the first half of the twentieth century.

  94. This is a propaganda video. You cannot attribute individual weather or fire events to global emissions of CO2. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis.

  97. Since 1900 the global temperature has increased by 1.3°C. Despite that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  99. @n1cemaiden879  I'm not arguing that humans have no effect on the climate. I am providing observation-based data from peer reviewed sources and reputable institutions. I am stating what has been discovered and what has not. I should not be trusted. You should not be trusted. Sceptiscim is good. Ultimately individuals should research these matters and decide for themselves.

  101. @JFB1111  I really don't think you understand... There is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling with little change in trend around the Equator (NOAA-STARv5 TLT & TMT 1979-2023). Overall the Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming globally. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade, so when you look at actual instrumental records the warming is uneven both spatially and temporally. This has little to do with CO2. The Earth's changing climate has extremely low sensitivity to CO2. This is supported by a huge body of scientific evidence.

  102. If it's not the hottest, then it must have cooled. The satellite data shows no warming trend for the past 8 years. There is no climate crisis.

  105. Dangerous propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

  107. There are no actual global observational data on changes to permafrost. The Li et al 2022 paper 'Changes in permafrost extent and active layer thickness in the Northern Hemisphere from 1969 to 2018' states "The temporal change characteristics of the permafrost extent and ALT [active layer thickness] for the NH [Northern Hemisphere] have not been studied." These things have only been poorly estimated or modelled. The aforementioned paper modelled permafrost extent decreased from 23.25 × 10⁶km2 (average from 1969 to 1973) to 21.64 × 10⁶km2 (average from 2014 to 2018), with a linear rate of −0.023 × 10⁶ km2/a. That's an annual change of 0.099 of a percent. That's negligible and could just as easily be increasing due to the uncertainty in the modelling. Out of global estimated emissions of methane of around 600 Tg CH4 per year, the best estimate of emissions from pan-Arctic permafrost is 1 Tg CH4 per year (Elder et al, 2021), so that's less than 0.17%. It's almost nothing. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades in the Arctic, and May 2023 was the coldest on record there. The Greenland surface mass balance (SMB) increase for the year 2022-23 was a massive - and well above 1981-2010 average - 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). Greenland has been cooling since 2012. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe. Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice - that can be used as a resting/hunting platform for seals and polar bears - hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. "Greenland ice sheet mass balance from 1840 through next week." (Mankoff et al., 2021). If you examine Fig.2 on page 5, you will see there would be no correlation with the exponential increase in the concentration of carbon dioxide (280ppm to 420ppm) and the change in the annual Mass Balance Sum shown in the paper. Indeed there have been periods of increasing mass of the Greenland ice cap in the 1940's, 70's, 80's and 90's. (Remember CO2 was rising all the time.) The Greenland ice sheet is thought to contribute 0.7mm/yr to sea-level rise, so 54mm by 2100 (just over 2 inches). That sounds small because it is small. Also an accounting error. More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere (14% of total human emissions). The average annual loss is 0.005% of the total mass (around 3 million gigatonnes). That's neglible. Come back in 20,000 years. There's no "death spiral" in the region as some people have reported. In fact, there is, I think, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  108. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There is no climate crisis.

  110. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, and that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021). Intergovernmental Panel on Climate Change (IPCC) AR6 report, Chapter 11,"Weather and Climate Extreme Events in Changing Climate" concludes that changes in the frequency and intensity of most severe weather events (with corresponding intense rainfall) have not been detected nor can they be attributed to human caused climate change.

  112. To assuage the fear of drought in the Amazon can I point out from the latest research "precipitation extremes during the preinstrumental nineteenth century indicate that recent floods and droughts on the Amazon River may have not yet exceeded the range of natural hydroclimatic variability." (Granato-Souza and Stahle, 2023)? And let's take a moment to remember The “Forgotten Drought” of 1865, plus "the recent river-level extremes on the Amazon may have been equaled or possibly exceeded during the preinstrumental nineteenth century."

  115. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

  116. This is nonsense. In the past people called this bad weather, and accepted these events as unpleasant but natural possiblilities. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  118. @SeekHistory  The British took a continent of people in which life for everybody was ugly brutish and short, plagued by the prospect of unremitting warfare, and the arbitrary exercise of power by self-appointed despots. Britain changed India into a land at Independence gifted with internal peace, the Law, Democracy, property rights, a growing population with improving health and education, a modern transportation system, and a developing economy. You're welcome. It took the Indians another 50 years before they made any real progress when left to their own devices. Largely because they were foolish enough to colonise themselves with another, much worse form of western imperialism, planned economy Marxism. The Indians were truly fortunate to have the British as the facilitators of their development for as long as they did.

  119. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  121. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades in the Arctic, and May 2023 was the coldest on record there. The Greenland surface mass balance (SMB) increase for the year 2022-23 was a massive - and well above 1981-2010 average - 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). Greenland has been cooling since 2012. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average.

  122. Horn of Africa, Somalia specifically, World Bank data shows annual rainfall is on an upward trend, and the climatic period 1931-1960 had far lower precipitation in all seasons than the period 1991-2020. Somalia's climate is wetter than in the past.

  123. Another climate propaganda video. Antarctic ice sheet mass loss is about 90 Gt/yr (Otosaka et al, 2023). It's total mass is 24 million Gt, so it loses less than 0.0004% of its mass annually. It contributes 0.36mm to sea-level rise per year (that's pitiful). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. The ice is here to stay.

  124. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. Imagine the damage done from all that resource extraction! And for what? Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  126. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS), and that is despite reports of supposed repeated bleaching, despite starfish predation and despite any bad weather. It should be renamed the Greatest Barrier Reef! If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020).

  127. Since 1900 the global temperature has increased by 1.3°C. Despite that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than that would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  128. 90% of these deaths are due to cold not heat. Also the climate is becoming less extreme. The marginal warming also appears to be largely due an increase in minima temperatures rather than maxima temperatures, i.e. warmer nights and winters. So essentially the climate is getting milder rather than hotter.

  129. When it comes to fires Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million and the lowest since 1998 (NIFC). Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there was nothing unusual about 2023 summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  130. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Lives will be saved. Warming is good not bad. A 2022 Lancet study reported 791 heat-related excess deaths and 60,753 cold-related excess deaths in England and Wales each year during the years spanning 2000-2019. That’s an excess death ratio of about 85 to 1 for cold vs. hot temperatures. Due to warmer urban temperatures, the number of premature cold-related excess deaths avoided averaged 447 per year from 1976-2019 in the city of London alone (Hajat et, 2024).

  131. This video lacks scientific foundations. Quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" That's between 60°N and 60°S, so pretty much where everyone lives.

  132. It is estimated that 5.1 million people annually die in association with non-optimal temperatures. 4.6 million are link to the cold, so over 90% (Zhao et al, 2021). And it is worst in the warmer parts of the world. 98% of temperature related deaths in SubSaharan Africa are due to the cold. Temperature events may be linked to upto 10% of human deaths annually. In a warming world there will be less death.

  133. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022 and 2023 (AIMS) despite repeated bleaching. In 2022, AIMS LTMP (long term monitoring programme) found record high coral cover on the Great Barrier Reef of 0.34 (i.e. 34% of the seabed on the coral reefs monitored are covered with coral). Over the past 36 years, cover has varied dramatically, and reached a low point in 2011 of 0.12. There was about twice as much coral in 2022 as in 2011. Since 2016 there has been a rapid rise in cover, despite four bleaching events occurring between 2016 and 2022. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate or to the concentration of carbon dioxide in the atmosphere. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. When it comes to storms destroying coral, who's expecting cyclones to become more frequent and intense. Using data from the JMA (1951-2022), we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years. Climate alarmists don't like this because it refutes all their failed predictions over many many years, so I have no agreement with the latest ones about the wrong type of coral on the brink of being destroyed by imaginary storms. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  136. Channel 4 propaganda. Antarctic ice sheet mass loss is about 90 Gt/yr (Otosaka et al, 2023). It's total mass is 24 million Gt, so it loses less than 0.0004% of its mass annually. It contributes 0.36mm to sea-level rise per year (that's pitiful). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. The ice is here to stay.

  137. @Jay Kanta  Very well then, if I must...it was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020, 2°C above present), and Minoan Warm Periods (Lécuyer, 2018, 4°C above present). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer), far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable. That one's been all over the news but if you want a citation I think it was in the 7th December 2022 issue of Nature. The original research was done by some Danish chappy. If you want some really rapid warming look at the CET (Central England Temperature) Instrumental Record between 1690 and 1730 (3°C increase). That might not be reliable enough for you though. Why not try the Dansgaard–Oeschger events? The Dansgaard–Oeschger events were global (Dima et al, 2018).About 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8 °C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. Some researchers believe the Medieval Warm Period was one of these, but I'm not convinced. However, I can provide upwards of 100 citations of science papers that together show the Medieval Warm Period was qualitatively and quantitatively warmer than the current warming, and that it was global in nature, focused around the year 1000.

  138. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  139. Global burned area has decreased by a quarter this century! For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data).

  142. @8fledermaus8  You're getting weather events mixed-up with climate. Food production: Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO).

  144. If this was the other way around (a heatwave in summer), that same man would ascribe it to Global warming/Climate change. If the Global Warming was a real thing with the Arctic warming faster than the tropics, then the temperature gradient would be less and it would be less stormy and cold. Satellite data shows no warming for the last 8 years.

  145. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. It's still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe. Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice that can be used as a resting/hunting platform for seals and polar bears hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. There's no "death spiral" in the region as some people reported. In fact, there is, as I say, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  154. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. So far in 2023 (upto 1st August, 2023) the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) is at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since that point. The climate crisis was 90 years ago. You missed it.

  156. @michaelfisher7170  I can't deny the data but it seems you can. America has by far the best instrumental data, and it shows overall the South East cooled in the last 120 years. Though that sentence doesn't do justice to the climate's variability. Data from NOAA (2021) shows uneven warming in the twentieth century focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day. That's the data. It's not mine. It's NOAA's.

  157. Get it right, Guenther. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). There is no climate crisis...there isn't even any evidence for it.

  160. It's hard to care, because there's nothing to care about. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  161. The extremely biased UN's IPCC AR6 report WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms evidence is lacking or the signal is not present for Fire Weather (hot and windy), leading to overall low confidence of an emerging signal both for the recent past or by 2050 even under the most extreme climate modelling (RCP 8.5).

  163. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in Absorbed Solar Radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with Total Solar Irradiance (how shiny the Sun is), which reached an all time record-breaking high in 2023 and 2024 as confirmed by satellite measurement (SORCE and TSIS). 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024).

  167. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis.

  168. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  170. @chrismckellar9350  Satellite data shows the Southern Hemisphere is cooling with Antarctica cooling by nearly 3°C in 40 years. The continent would need to warm for the ice cap to melt. Also, overall, the ice shelves around the coast have enlarged. There is, however, a record low in the annular sea ice this year (record high 2014 with no trend overall). It's too early to conclude why this is but my guess is if you took away El Niño, a record increase in Total Solar Irradiance, and the Tonga eruption (all natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2.

  171. Propaganda. Alberta, May is historically the month when most forest fires occur. There is no trend for burn acreage, with the largest recorded for 1959-2019 being in 1981. For the whole of Canada the largest burn acreage was 1989, and there is again no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB).

  172. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

Cities will sink into the ocean. 2006 10 years until a point of no return. 2007 if no action 2012 will be too late. Also 2007 Arctic ice free 2010, or 2015, or 2013, or 5 years take your pick. 2008 the Arctic ice sheet would melt away. Also 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 Arctic ice free in 2014. 2012 snow will be gone by 2020. 2013 Methane catastrophe in 2 years because of ice free Arctic. 2018 zero chance of permanent ice in Arctic by 2022.

  179. There is no climate crisis. The Earth was warmer in the recent and distant past. It has warmed faster in the past. Adding CO2 to the atmosphere has greened the Earth by 15% in 20years (so NASA says). Especially in marginal areas such as the Sahel as it increases drought tolerance. And how come everywhere is warming more than the average?

  180. The Royal Society recommend the UK should have 100TWh of energy storage by 2050 (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. A typical pumped storage facility has a 300 to 400m dam built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming huge amounts of copper and other rare metals for the next 25 years. 1.5 billion tonnes of concrete 42 million tonnes of steel (which is going to need 27 million tonnes of coking coal) 1.9 million tonnes of copper 1.3 million tonnes of zinc 184,000 tonnes of manganese 122,000 tonnes of chromium 56,000 tonnes of nickel 54,000 tonnes of other critical minerals. No doubt all of these materials will be ethically sourced using low carbon processes. Nuclear power would require less than ½ of these resources and Coal power around ¹/10th. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the less than 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the whole Earth going Net Zero. Good luck with that.

  182. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%!

  185. Since 1900 the global temperature has increased by 1.3°C. In that time humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  187. The Germans were always good at propaganda. "The most robust global changes in climate extremes are found in yearly values of heatwaves (number of days, maximum duration and cumulated heat), while global trends in heatwave intensity are not significant. Daily precipitation intensity and extreme precipitation frequency are stationary in the main part of the weather stations. Trend analysis of the time series of tropical cyclones show a substantial temporal invariance and the same is true for tornadoes in the USA. At the same time, the impact of warming on surface wind speed remains unclear. The analysis is then extended to some global response indicators of extreme meteorological events, namely natural disasters, floods, droughts, ecosystem productivity and yields of the four main crops (maize, rice, soybean and wheat). None of these response indicators show a clear positive trend of extreme events. In conclusion on the basis of observational data, the climate crisis that, according to many sources, we are experiencing today, is not evident yet." (Alimonti, et al. 2022. The European Physical Journal Plus, Volume 137.) The climate crisis is nonsense.

  188. In the current interglacial Svalbard has been far warmer than today. Using biomarker evidence (for example, the Early Holocene presence of sea creatures unable to survive below fixed warmth thresholds) and glacier melt extent measurements (for example, sea shells buried 6 km inside a glacier), scientists have discovered that much of Arctic Svalbard was about 7°C warmer than today during the Early Holocene, when CO2 concentrations were much lower (near 260 ppm) (Farnsworth et al, 2020. Leopold et al, 2019. van der Bilt et al, 2019. Łacka et al, 2019. Beierlein et al, 2015). Anyway the Arctic has already been ice free in the current interglacial. It was certainly warm enough during the Holocene Climatic Optimum, being upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean, far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures when compared to today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. So no ice in the ocean, and the world survived. These changes emerged in the Earth's climate system without any human input.

  191. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests.

  192. Weather events are not climate. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021.

Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century.

  193. Our "food systems" are doing just fine. Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). 2023 is another record cereal crop. There is no global climate crisis. There is no evidence of one.

  196. @scottekoontz  As stated, 1930s heatwaves were many times worse than today's. You start in the 1960s because that was a cooler decade so it's bound to flatter more recent decades. I made a reference starting in 2005 because the USCRN started collecting data then, but you wouldn't know that.

  197. There is no climate crisis. The Earth was warmer in the recent and distant past. It also warmed faster. The extra CO2 in the atmosphere is having a fertilising effect making plants more drought tolerant, and greening the Earth by 15% in the last 20 years.

  201. The case is not closed. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  202. @Lorax61  I'll take it where I like. By the way, your third sentence was incoherent. Also, don't worry, there is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  203. Global burned area has decreased by a quarter this century! For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). There is no climate crisis...there isn't even any evidence for it.

  204. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Increased CO2 causes this in two ways: it has a direct fertilising effect (the CFE), and it increases drought tolerance by reducing stomata. This greening of the Earth due to CO2 is now "an indisputable fact" (Chen et al, 2024). In fact, 55.15% of those areas greening have been doing so at an accelerated rate since 2001. Since the start of the Industrial Revolution the Earth's primary productivity has increased by more than 30% (Campbell et al, 2017 and Haverd et al, 2020). Zhu, Piao, & Myneni, 2016 calculate that 70% of Earth’s global greening in the modern period is due to CO2 and only about 13% is due to fertilizer and land use changes by humans. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests.

  205. If you took away El Niño and Tonga (both natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP. There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

  206. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  207. Channel 4 propaganda. "Greenland ice sheet mass balance from 1840 through next week." (Mankoff et al., 2021). If you examine Fig.2 on page 5, you will see there would be no correlation with the exponential increase in the concentration of carbon dioxide (280ppm to 420ppm) and the change in the annual Mass Balance Sum shown in the paper. Indeed there have been periods of increasing mass of the Greenland ice cap in the 1940's, 70's, 80's and 90's. (Remember CO2 was rising all the time.) The Greenland ice sheet is thought to contribute 0.7mm/yr to sea-level rise, so 54mm by 2100 (just over 2 inches). That sounds small because it is small. Also an accounting error. More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere (14% of total human emissions). The average annual loss is 0.005% of the total mass (around 3 million gigatonnes). That's neglible. Come back in 20,000 years. There's no "death spiral" in the region as some people have reported. In fact, there is, I think, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  209. We are not in a climate crisis when you look at the data: Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA).

  211. @komousch  Oh climate is changing natural systems, but for our betterment. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019).

The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. Banana production has doubled in 20 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). 2023 was another record cereal crop. There is no climate crisis.

  212. In retrospect, this is b*ll*cks. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. If we look at the Global Coral Reef Monitoring Network (GCRMN) data (which isn't ideal for various reasons) the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth.

  213. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe. Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice that can be used as a resting/hunting platform for seals and polar bears hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. There's no "death spiral" in the region as some people reported. In fact, there is, as I say, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  214. The case is not closed. This scientific consensus idea (usually 97%) comes from a paper by Cook et al in 2013. They reviewed 11,944 climate science papers. 66.4% (7,930) expressed no opinion on 'global warming', and were wrongly discarded. 3% (118) of papers with an opinion rejected GW (Hence the 97% nonsense). The reality was only 24% (2,910) of the papers that they looked at were in support of GW. Only 8% (986) endorsed the view that GW was anthropogenic i.e. man-made. Only ½% (64) supported the IPCC view of AGW. So not 97%, ½%. Because of such perfidy, all climate scientists are now paid and funded to research and agree with AGW. (Look at what happened to Ridd, Curry, Ball, Svenmark, Bellamy). And don't forget to remind Dr John Clauser, Ivan Giaever, Robert Laughlin, Edward Teller and the rest about the consensus, they must have missed the memo. A poll of scientists (meteorologists, physicists, geologists, hydrologists, and climatologists) conducted by the Fairleigh Dickinson University and completed in October 2022 found 59% thought climate change will cause "significant harm", but 39% said either “significant improvement,” “slight improvement,” “no change,” or “slight harm.” That's not a consensus. Any claim of a consensus that “science is settled” regarding the existence of a dire climate crisis emergency caused by carbon dioxide is a deceptive, destructive, and costly fraud. A “World Climate Declaration” made public in August, 2023 endorsed by 1,609 informed scientists and professionals — including two Nobel Laureates, John Clauser (USA) and Ivar Giaever (Norway/USA) — clearly says otherwise.

Cool, damp and dull for the foreseeable future. 10 times the number of people die from the cold than the heat.

  216. There are no actual global observational data on changes to permafrost. The Li et al 2022 paper 'Changes in permafrost extent and active layer thickness in the Northern Hemisphere from 1969 to 2018' states "The temporal change characteristics of the permafrost extent and ALT [active layer thickness] for the NH [Northern Hemisphere] have not been studied." These things have only been poorly estimated or modelled. The aforementioned paper modelled permafrost extent decreased from 23.25 × 10⁶km2 (average from 1969 to 1973) to 21.64 × 10⁶km2 (average from 2014 to 2018), with a linear rate of −0.023 × 10⁶ km2/a. That's an annual change of 0.099 of a percent. That's negligible and could just as easily be increasing due to the uncertainty in the modelling. Out of global estimated emissions of methane of around 600 Tg CH4 per year, the best estimate of emissions from pan-Arctic permafrost is 1 Tg CH4 per year (Elder et al, 2021), so that's less than 0.17%. It's almost nothing. When it comes to tipping points this is what the IPCC (Special Report on implications of 1.5C or more warming, Chapter 3) says:“there is little evidence for a tipping point in the transition from perennial to seasonal ice cover. No evidence has been found for irreversibility or tipping points, suggesting that year-round sea ice will return given a suitable climate”. The IPCC also do not believe the melting of the arctic permafrost will cause a tipping point in the release of warming methane gas “the carbon released to the atmosphere from thawing permafrost is projected to be restricted to 0.09–0.19 Gt C yr–1 at 2°C of global warming and to 0.08–0.16 Gt C yr–1 at 1.5°C, which does not indicate a tipping point”. The Earth's climate is a multi input thermodynamic system and will conform to Le Chatelier's Principle.

  218. Please be aware that the IPCC's (Scenario A) modelled predictions are junk. Back in 1990 they predicted a warming of 0.30-0.34°C per decade. Of course we've only had 0.13°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it! But there is still no crisis just an unexciting set of observations. All the climate models run too hot, 100% of them.

  220. There is no climate crisis. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis.

  221. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  223. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). A study by Venter et al (2018) found the Sahara desert had shrunk by 8% over the previous three decades. The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century.

  225.  @PremierCCGuyMMXVI  There's very little to ignore: Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked for each set of satellite data (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere, but can be correlated to multi-decadal oscillations in ocean circulation. It's going to be decades before even your big toe is submerged. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century. The retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this. Globally satellite data shows how variable the Earth's climate is with changes up or down of more than 1°C occurring from one year to the next. However, overall the Earth's ecosystems are resilient to these fluctuations, as most species are eurytopic enough to survive these changes. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There really is no climate crisis.

  226. In the past few months, the World's Sea Surface Temperature (SST) has declined by 0.5°C so that it has returned to the temperature in December 2015 (Daily Sea Surface Temperature World 60°N-60°S 0-360°E NOAA OISST V2.1 dataset available on the ClimateReanalyzer website). The recent off trend temperature rise began before El Niño and was not predicted by climate scientists. The size of the temperature rise was not predicted by climate scientists. The rapid cooling of the ocean back down 2015 levels before the commencement of the next La Niña was not predicted. If the heat energy content of the World's oceans has increased by 400ZJ since 1960, and the atmosphere has absorbed about ¹/100 th that amount, there is no way an increase of 100ppm of CO2 into the atmosphere has forced that much heat into the ocean. The atmosphere does not hold enough energy, plus infrared radiation cannot penetrate the ocean surfaces beyond a few millimeters (small fractions of an inch) so increasing atmospheric CO2 cannot be an explanation of ocean warming It is not possible for the energy in the atmosphere to affect the ocean temperature changes seen recently or in the long term. In fact the atmosphere is not trapping more energy as the "greenhouse gas" CO2 increases, but the atmosphere is emitting increasing amounts of energy into space as longwave radiation. This is contrary to the idea of man-made global warming. Nearly all of the energy the ocean receives comes directly from sunlight. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in Absorbed Solar Radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with Total Solar Irradiance (how shiny the Sun is), which reached an all time record-breaking high in 2023 and 2024 as confirmed by satellite measurement (SORCE and TSIS). 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024).

  227. The mirage of a climate crisis has hardened into a delusion. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  228. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  229. @jaspercaelan4998  You're responses are worded so that they sound plausible, and make you seem knowledgeable, but they are all completely unsupported, and largely just plain wrong. Take your point about "short term variations", the CERES data referred to by Goessling and in my original comment stretches back to 2000 (data: CERES Ebaf4). It shows an increase in net solar radiation over the period 2000-2023 of approximately 1.3 W/m². The long-term positive trend in shortwave radiation has been confirmed to exist since 1983 (Pinker et al, 2005). The period 1983-2001 shows an increase of 1.6W/m² per decade (1% increase per decade). That there is an established trend for 40 years makes it climatologically significant i.e. not "short term variation". NASA claims that a reduction in albedo of 1 percentage point produces a warming effect equal to a doubling of CO2 in the atmosphere (Wielicki et al, 2005). Accordingly, the albedo decrease we have had in the last 24 years corresponds to +2.0 W/m². The increase in CO2 corresponds to a theoretical increase of only +0.7 W/m². So the ongoing, longterm reduction in albedo and consequential increase in ASR has produced nearly three times as much warming effect in recent decades as the potential radiative forcing from CO2. Your statement "man made emissions is causing most of the warming" is wrong.

  232. As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’

  234. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from this period. No temperature anomalies from 2000-2019 reach 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005.

  237. @8fledermaus8  If you took away El Niño, a record increase in Total Solar Irradiance, and the Tonga eruption (all natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Total solar irradiance: satellite data from 1979 onwards shows June 2023 at an all time high in over 40 years of measurements (ncei.noaa). There were lows below 1361 W/m² in 2019 to current highs over 1362 W/m² in June (using a lowess curve, which also shows the fastest rate of increase during this recent period). So we are looking at a change of around 1½ Watts over the course of 5 years (the maximum difference is 2.1W/m²). That may not sound much but it exceeds the increase in the Earth's Energy Imbalance (0.9 W/m², 2018 - 1.97 W/m², 2023) (NASA CERES EBAF TOA). Overall the current increase in solar irradiance should give a direct global heating effect of +0.1°C, with an indirect effect of +0.2°C (after Schmutz, 2021). This increase in solar irradiance is related to an earlier than expected increase in sunspot activity, which has not yet reached its zenith, and that may not happen for several years (Royal Observatory Belgium), so further heating from this cause can be expected. So increase in TSI 2019- 2023 = 2.1W/m2. Increase in EEI for the same period ≈ 1W/m². Maybe I'm being dense, but doesn't that mean that without the increase in TSI, the EEI would be in negative territory? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

  239. @time_warriors  Utter tosh. The British took a continent of people in which life for everybody was ugly brutish and short, plagued by the prospect of unremitting warfare, and the arbitrary exercise of power by self-appointed despots. Britain changed India into a land at Independence gifted with internal peace, the Law, Democracy, property rights, a growing population with improving health and education, a modern transportation system, and a developing economy. You're welcome. It took the Indians another 50 years before they made any real progress when left to their own devices. Largely because they were foolish enough to colonise themselves with another, much worse form of western imperialism, planned economy Marxism. The Indians were truly fortunate to have the British as the facilitators of their development for as long as they did.

  240. No. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.

  244. Since 1900 the global temperature has increased by 1.3°C. Despite that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than that would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  247. The developed world is not exporting bad weather. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  248. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  250. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see. Have children.

  251. For studies of drought patterns in Europe: Vincente-Serrano et al. 2020 “Our study stresses that from the long-term (1851–2018) perspective there are no generally consistent trends in droughts across Western Europe.” Oikonomou et al. 2020 “One of the central outcomes of this research is that there is little change in drought characteristics for 1969–2018. It also seems, no particular tendencies for more or less frequent droughts in the two major geographical domains of Europe are present.” IPCC AR6: “in areas of Western and Central Europe and Northern Europe, there is no evidence of changes in the severity of hydrological droughts since 1950” so all the way from the western tip of France to Moscow.

  255. @robdavidson2569  Really? Didn't you know? There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  256. This video obscures the truth. Go back to the source, the Norwegian Meteorological Office (Seklima), to try to get to the bottom of this. I suggest everyone check out their data. Ny-ålesund data for maximum annual temperatures shows no trend since records began in 1969. It has not got hotter. However, the minimum annual temperatures has increased, so the winters have become milder (but still extremely cold). The increase in the annual minimum temperature occurred over 20 years, but this trend stopped around 2006. To find a longer term view on Svalbard you need to look up other weather stations, for example Longyearbyen + Svalbard Lufthavn. Looking at say 1950 to the present shows no trend in the maximum temperatures. The minima dropped quite considerably from the later 50s. The 60s and 70s had an intensely cold trend of minima. It then warmed in the 80s/90s and from 2005 levelled off. So overall the swings in temperature on Svalbard during the year have become less extreme. Very roughly, it hasn't got hotter, but the winters, which got very much colder, became less cold, now they have stopped getting less cold since about 2005. Svalbard's climate became milder, less extreme than compared to the 60s and 70s, but not hotter. That process of amelioration has stopped. These changes are uncorrelated to the level of CO2 in the atmosphere.

  257. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data).

  261. @catherinewilliams9680  If you're worried about deaths due to climate, cold temperature events are the big killer, not heat. It is estimated that 5.1 million people annually die in association with non-optimal temperatures. 4.6 million are linked to the cold, so over 90% (Zhao et al, 2021). And it is worst in the warmer parts of the world. 98% of temperature related deaths in SubSaharan Africa are due to the cold. Temperature events may be linked to upto 10% of human deaths annually. In a warming world there will be less death. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Lives will be saved. Warming is good not bad. A 2022 Lancet study reported 791 heat-related excess deaths and 60,753 cold-related excess deaths in England and Wales each year during the years spanning 2000-2019. That’s an excess death ratio of about 85 to 1 for cold vs. hot temperatures. Due to warmer urban temperatures, the number of premature cold-related excess deaths avoided averaged 447 per year from 1976-2019 in the city of London alone (Hajat et, 2024).

  262. @catherinewilliams9680  "As regards disease, the Lancet's Countdown on Health and Climate Change (2019) shows Climate-related deaths are a small proportion of all-cause fatalities (1990–2017). That is based on data per IHME (2019), and between 1990 and 2017, the cumulative age-standardized death rate (ASDRs) from climate-sensitive diseases and events (CSDEs) dropped from 8.1% of the all-cause ASDR to 5.5%, while the age-standardized burden of disease, measured by disability-adjusted life years lost (DALYs) declined from 12.0% to 8.0% of all-cause age-standardized DALYs. Thus, the burdens of death and disease from CSDEs are small, and getting smaller. However, the declines in death and disease rates from CSDEs since 1990 are only a small proportion of longer-term declines across the globe. In the USA, one of the few places with good long-term data, death rates from dysentery, typhoid, paratyphoid, other gastrointestinal diseases, and malaria – all water-related diseases and therefore, almost by definition, climate-sensitive declined 99–100% between 1900 and 1970. We are solving our problems with CSDEs faster than we are solving our other health problems." Indur M. Goklany

  263. The climate attribution studies are based on the relative frequency of daily temperatures in the current climate and in a world without human-caused climate change. Unfortunately, one cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no extra CO2 had been added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  266. The famine in the Horn of Africa is endemic not because of climatic factors but because of bad governance and poverty. If you compare these regions to the Gulf States, the climate of the Gulf is similar, although even drier, but the latter have a much higher standard of living due their wealth of fossil fuels and better social organisation. What the Horn of Africa needs is a good dose of reliable energy from fossil fuels to raise their living standards.

  267. More propaganda from Auntie Beeb. There is no drying trend for rainfall in Syria. The natural environment is arid or semi-arid. The rainfall is naturally highly variable both spatially and temporally. "We conclude that there is no evidence of progressive multi-decadal drying either in the Fertile Crescent region as a whole, or in northeast Syria specifically." Selby et al. 2017.

  268. This is climate change: There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth.

Global temperatures maxed out in 2016 and have been lower ever since (UAH v6 global satellite data). 500 billion tonnes of emissions in that time, and no warming. There is no climate crisis.

  270. Time for some information ladies: The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  271. @chow-chihuang4903  Our food supply has been impacted positively. Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO).

  272. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million, the lowest since 1998 (NIFC), and 3% of the burn in the 1900s. Annual share of the total land area burnt by wildfires in the US went from 0.6% (2012) to 0.4% (2024)(GWIS/FAO UN). There's basically no increasing trend in the data. The areas burnt are comparatively tiny.

  274. Vanuatu has an annual sea-level rise averaging 3mm a year, probably since the end of the ice age. That's the same as everywhere else as measured by tide gauges, so stand on a beach ⛱️ for a century and your ankles might get wet. The actual sea-level anomaly for Vanuatu has been on a declining trend since 2012. In fact the sea level change in a single year (60mm up and down) is 20 to 30 times greater than the trend. It's typhoons that they need to worry about, and fortunately, they've been decreasing for over 7 decades (thanks global warming 👍). The truth is Atolls in the Pacific nations, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8% in size. But the truth isn't scary or exciting...and there's no money in it.

  275. @astronautical1082  Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There is no climate crisis.

No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data).

  279. The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. )

  280. What are we fixing? Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017.

Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  281. There is no climate crisis. The Earth was warmer in the recent and distant past. It also warmed faster in the past. The problem is bad weather, poverty, bad governance and lack of resources especially fossil fuels. Compare this situation to that of the Gulf states. These people need fuel to power their development.

  283. @andrew30m  There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! There's always bad weather somewhere in the world. As regards the belief in weather event attribution the IPCC states “Scientists cannot answer directly whether a particular event was caused by climate change, as extremes do occur naturally, and any specific weather and climate event is the result of a complex mix of human and natural factors. Instead, scientists quantify the relative importance of human and natural influences on the magnitude and/or probability of specific extreme weather events.” It is not possible to attribute whether an individual heatwave, drought or a flood, or any climate event, extreme or otherwise is due to human factors. People are fooled into believing it is, thanks to the magic of attribution science. One cannot prove that changes in the climate are man-made, but in tactical attribution science it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs (greenhouse gases) are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science. It's wishful thinking often expounded for legal or political purposes as WWA’s (World Weather Attribution) chief scientist, Friederike Otto, freely admits, “Unlike every other branch of climate science or science in general, event attribution was actually originally suggested with the courts in mind.”

  284. Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. Banana production has doubled in 20 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). 2023 was another record cereal crop.

There is also evidence of the continent being the home to rainforests further back in time. However the ice sheets are huge and the possibility that they will shrink to any degree in the next 100 years is neglible.

From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades.

  293. 10:27 In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022) (NOAA's Arctic Report Card, 2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

  294. Channel 4 propaganda. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades in the Arctic, and May 2023 was the coldest on record there. The Greenland surface mass balance (SMB) for the past 11 months is a massive but very normal 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. There is no climate crisis.

  296. The Norwegian Meteorological Institute (MET Norway) has data for Barentsburg and Svalbard Lufthavn (Airport) on Svalbard up in the High Arctic. The data ranges from 1912 to the present. This data shows an extremely rapid warming in the 1910s, 1920s and into the 30s. There was around 8°C of warming in 20 years. That's far, far greater than the illusory warming for the past twenty years being proselytised here. Maximum annual temperatures have no trend - it's not getting hotter. Minimum annual temperatures have increased - it's getting milder. There is no climate crisis.

  297. @yeahshell5166  The data is as I have described, but I suggest you research it for yourself. There is no evidence of cataclysmic warming in the Arctic. The sea ice extent around Svalbard is similar to the eighteenth century. It increased in the nineteenth and declined intermittently in the twentieth. This is a small part of the Arctic and a tiny part of the globe. It is focused on because it fits the simple story of dangerous warming. If one were to look at another part of the globe, say the southeastern United States, you would find that it had cooled since the start of the twentieth century, and that is based on far more reliable and extensive data. But you won't hear that on the news. Notice, in the video, for example, the temperature rise given of "nearly 8 degrees ", that was in winter and will have no effect on ice extent as it remains well below freezing even if it has "warmed".

The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  300. There is no climate crisis. The Earth was warmer in the recent and distant past. It also warmed faster in the past.

  301. Glacial retreat is not evidence of a climate crisis. The retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). In Alaska's Glacier Bay the melt rate from 1780 to 1880 was much greater than the melt rate from 1880 to the present. There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  302. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  304. America has by far the best instrumental data, and it shows overall the South East cooled in the last 120 years. Though that sentence doesn't do justice to the climate's variability. Data from NOAA (2021) shows uneven warming in the twentieth century focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West US showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day.

  305. The naughty little truant should go back to school and learn something. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920. Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, and that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021). What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). Global temperatures maxed out in 2016 and have been lower ever since (UAH v6 global satellite data). 500 billion tonnes of emissions in that time (14% of all man-made CO2) and no warming. There is no climate crisis.

  306. There is no observational evidence that we are living in a global climate crisis. The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms evidence is lacking or the signal is not present, leading to overall low confidence of an emerging signal both for the recent past or by 2050 even under the most extreme climate modelling (RCP 8.5): Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Severe Wind Storms, Glacier, and Ice Sheets, Tropical Cyclones.

  308. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. Deserts have shrunk considerably since the 1980's and the Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs.

  309. @user-zy4wv7yx1z  Can I recommend “In Search of Climate Crisis in Greece Using Hydrological Data” (Koutsoyiannis et al, 2023)? It shows since records began in the mid-nineteenth century, there is no long term climate variability. Apart from it being slightly wetter in 1990-2020 than 1960-1990. Also the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it. I hope you feel educated now. After all, there's no excuse.

  310. So nothing Britain does has any effect. Addendum: There is no objective observational evidence that we are living in a global climate crisis. Even the biased UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856,  section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Mean precipitation,  Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones.

  315. @Lies Tricks The majority of record hot temperatures are from the 1930s. The Medieval Warm Period was so warm grape vines could be harvested economically in the North of England, the tree line in in Canada was further north than it is today, and there were birch forests on Greenland which allowed large scale Viking settlement. During the Holocene Climate Optimum it was so warm trees grew on the shores of the Arctic Ocean and that ocean was probably ice free. In the previous interglacial it was even warmer and sea levels were much higher. The current warming began before the Industrial Revolution and the burning of fossil fuel. No lies. All truth. Have a lovely day.

  316. There is no climate crisis. Wind is due to the temperature difference between the Tropics and Arctic. If the Arctic is warming faster than the Tropics the temperature difference should be less, and shouldn't the wind speed decrease.
    3
  317. As regards regards the rate of temperature change, the warming in the current modern era has been neither consistent nor rapid both temporally and spatially. The climate of the US in the 20th century is good example of this. The US has by far the best actual temperature recordings for this period with very little coverage elsewhere outside of Europe. Data from NOAA (2021) shows uneven warming focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day. All of this demonstrates to my mind that the climate has a strong internal variability without the requirement for any external anthropogenic forcing. Globally satellite data shows how variable the Earth's climate is with changes up or down of more than 1°C occurring from one year to the next. However, overall the Earth's ecosystems are resilient to these fluctuations, as most species are eurytopic enough to survive these changes.

  321. Since 1900 the global temperature has increased by 1.3°C. Despite that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than the would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  323. Heat waves have not been increasing in intensity or frequency in the United States, which has by far the best meteorological data both spatially and temporally. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. In 2023 only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century.

  325. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  328. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 908 known lost species for 2.1 million known species in 500 years (IUCN Red List), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data).

  330. Another climate propaganda video. Antarctic ice sheet mass loss is about 90 Gt/yr (Otosaka et al, 2023). It's total mass is 24 million Gt, so it loses less than 0.0004% of its mass annually. It contributes 0.36mm to sea-level rise per year (that's pitiful). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. The ice is here to stay.

  332. The 'Cold Blob' has disappeared from North Atlantic surface temperatures, when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising almost by +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact.

  334. There is nothing unusual about the fire season in Europe. Weekly burn area is way below average. Cumulative burn area is average. Weekly Number of fires are below average. Cumulative number of fires are bang in the middle of the normal range. The same is true for Greece, and the fires at present are a tiny fraction of the maximum recorded (EFFIS). There's no trend for wildfires in Greece. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus).

  336. @Aaronwhatnow  The AIMS Long-term Monitoring Programme (LTMP) data for the GBR started in 1985. At the start of the data sequence for the whole GBR cover was 25% in 1986. It reached a low point in 2011 of 12%. In 2022, the LTMP found record high coral cover on the GBR of 34% coral cover on the seabed of the coral reefs monitored. Increases in bleaching events has not prevented rapid and record increases in coral cover. AIMS states "Percent hard coral cover is one standard measure of reef condition recorded by scientists worldwide, it provides a simple and robust measure of reef health" with that in mind, and it being such a robust measure, let's just say it loud and clear: hard coral cover is at record-equalling levels in all three sectors of the GBR.

  337. @Aaronwhatnow  You'll have to be specific about which reports. I have certainly read some reports. Here's a prècis: The Northern region reached a low point in 2016. However, it has since completely recovered, with coral cover now at double the 2016 level, and recording record cover. The Central region has experienced a greater degree of fluctuation, but is also now at record high coral cover. The Southern region is now at record equalling coral cover, three times higher than at its low point in 2011. Every region is at record-equalling high coral cover, once uncertainty estimates are taken into account. For example take Capricorn Bunkers. This is one of the sections within the Southern Region (one of eleven). In 2022, Capricorn Bunkers had record high coral cover of 59%, around four times the lowest value, seen in 2011, of 16%. This doesn't do it justice though as the data for the reef shows a great degree of variability. This is natural. The reef always recovers strongly. And it's got nothing to do with CO2. Increases in bleaching events has not prevented rapid and record increases in coral cover. AIMS states "Percent hard coral cover is one standard measure of reef condition recorded by scientists worldwide, it provides a simple and robust measure of reef health" with that in mind, and it being such a robust measure, let's just say it loud and clear: hard coral cover is at record-equalling levels in all three sectors of the GBR. Crown of Thorns Starfish are also a non-problem. Northern: no starfish or no outbreak on all reefs. Central: no starfish or no outbreaks. Southern: out of 30 reefs, 27 had no starfish or no outbreaks. And once more, oh yes, there is record hard coral cover on the Great Barrier Reef. And that is a robust measure of reef health. What a robust reef!

  338. Propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). There is no climate crisis.

  341. The Arctic minimum summer sea ice trend is zero for the past 18 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 2024 4.28 Plot the trend line for this data and it will be flat. ZERO net change in 18 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). They also noted "the Arctic temperature was higher in the 1930s–40s than in recent decades, and hence a trend calculated for the period 1920 to the present actually shows cooling." Zhang (2021) showed there was no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Including more recent satellite data from Cryosat-2 (2010-2023)reveals the Arctic ice volume minimum (Oct-Nov) is increasing at 56km³/yr (Kacimi and Kwok, 2024). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), an El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  343. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021).

  344. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  345. What happens if we get 56 days of "dunkelflaute" like the UK got in 2018? Projecting out to 2050 with increased demand from electrification of transport and heating etc, we would need to find something like 28TWh of missing electricity generated from wind power (but the wind won't be blowing!). Britain currently has 39.3 GWh of pumped storage. There are 4 pumped storage stations in Britain. No storage capacity has been added to the grid since the 1980s, and there is no other large scale energy storage in the country. To cover a cold dark still winter you would need to increase pumped storage capacity by a factor of about 1000 (taking into account pumped storage is about 75% efficient). So we would need to find 4000 suitable locations where a 300 to 400m dam can be built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. Then we would have to build 160 of these every year, year after year, for 25 years. The scale, and the massive cost of storage, by whatever method (pumped storage is one of the cheapest by the way), make it an impossible mission.

  346. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis.

  349. Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  351.  @acajoom  Same again. Your argument is fallacious.

  352. As regards the belief in weather event attribution the IPCC states “Scientists cannot answer directly whether a particular event was caused by climate change, as extremes do occur naturally, and any specific weather and climate event is the result of a complex mix of human and natural factors. Instead, scientists quantify the relative importance of human and natural influences on the magnitude and/or probability of specific extreme weather events.” It is not possible to attribute whether an individual heatwave, drought or a flood, or any climate event, extreme or otherwise is due to human factors. People are fooled into believing it is, thanks to the magic of attribution science. One cannot prove that changes in the climate are man-made, but in tactical attribution science it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs (greenhouse gases) are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science. It's wishful thinking often expounded for legal or political purposes as WWA’s (World Weather Attribution) chief scientist, Friederike Otto, freely admits, “Unlike every other branch of climate science or science in general, event attribution was actually originally suggested with the courts in mind.”

  353. It had better start warming up. We've added 500 million tonnes of CO2 to the atmosphere in the last eight years but in each of those years the global temperature has been below the 30 year mean. Oh dear. Higher CO2, lower temp. Whoops. 🤭

  354. Propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

  355. ​@lubobir Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. Banana production has doubled in 20 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). 2023 was another record cereal crop. Increases in cereal production since 1961: Africa +384%, Asia +348%, Australia +458%, Europe +110%, North America +184%, South America +547%. Percentage increase in production in all regions also exceeded the percentage increase in population. Global and regional food security is improving. 2024-2025 will see another record high production of wheat, soybeans and rice. Compared with a decade ago, the world will harvest in 2024-25 about 10% more wheat, about 15% more corn, nearly 30% more soybeans, and about 10% more rice. Global food supply (kcal per capita per day) has increased from 2181kcal in 1961 to a record 2959kcal in 2021.

  357. @komousch  "As regards disease, the Lancet's Countdown on Health and Climate Change (2019) shows Climate-related deaths are a small proportion of all-cause fatalities (1990–2017). That is based on data per IHME (2019), and between 1990 and 2017, the cumulative age-standardized death rate (ASDRs) from climate-sensitive diseases and events (CSDEs) dropped from 8.1% of the all-cause ASDR to 5.5%, while the age-standardized burden of disease, measured by disability-adjusted life years lost (DALYs) declined from 12.0% to 8.0% of all-cause age-standardized DALYs. Thus, the burdens of death and disease from CSDEs are small, and getting smaller. However, the declines in death and disease rates from CSDEs since 1990 are only a small proportion of longer-term declines across the globe. In the USA, one of the few places with good long-term data, death rates from dysentery, typhoid, paratyphoid, other gastrointestinal diseases, and malaria – all water-related diseases and therefore, almost by definition, climate-sensitive declined 99–100% between 1900 and 1970. We are solving our problems with CSDEs faster than we are solving our other health problems."

Jevrejeva, et al (2014) estimated 2 mm/year (± 0.3), and Church and White (2006) estimated 1.7mm/year (± 0.3).

  360. @komousch  When you use data from the World Bank and global insurance, and try to measure the cost to society of climate change, you find the cost is minimal and diminishing. Global weather losses as a percentage of Global GDP sank from 0.25% to below 0.20% between 1990 and 2022. Based on data published in the Lancet in 2019, GDP percentage Climate-Related Disaster Losses have declined in all global income categories, with the most noticeable declines in the lower income countries (Watts et al., 2019).
    3
  361. @komousch  There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! As an example of good news, Climate Change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades.

  362. @komousch  So I referenced 8 internationally renowned scientific organisation plus important relevant scientific papers that refute your position, and it's cherry-picking. Have some more cherries. "Greenland ice sheet mass balance from 1840 through next week." (Mankoff al., 2021). If you examine Fig.2 on page 5, you will see there would be no correlation with the exponential increase in the concentration of carbon dioxide (280ppm to 420ppm) and the change in the annual Mass Balance Sum shown in the paper. Indeed there have been periods of increasing mass of the Greenland ice cap in the 1940's, 70's, 80's and 90's. (Remember CO2 was rising all the time.) The Greenland ice sheet is thought to contribute 0.7mm/yr to sea-level rise, so 54mm by 2100 (just over 2 inches). That sounds small because it is pitifully small. Also an accounting error. More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere (14% of total human emissions). The average annual loss is 0.005% of the total mass (around 3 million gigatonnes). That's neglible.

  363. @komousch  Another cherry! The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". A study of Antarctic ice shelves from 1980 to 2021 (Banwell et al, 2023) showed meltwater volume dropped with "decreasing trend in both annual melt days and meltwater production volume over the 41 years.” "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high. Antarctica contributes 0.36mm to sea-level rise per year (that's essentially nothing as well). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. That ice is here to stay.

  367. Propaganda. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. It's still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe.

  370. @Niko257x  The big problem for doomists is peak interglacial warmth is not now but around 8,000 years ago. Proxies show a downward trend to the present day but with an interruption for the Medieval Warm Period (that doomists aren't allowed to believe in) followed by a decent into the The Little Ice Age (which doomists think also didn't exist), and a very slight recovery to the present day still below MWP though. Now I know what you're going to say about the supposed rapid warming over the last century but that's not a fair comparison. That's instrumental - which is unreliable due to it poor spatial and temporally collection -with annual instrumental measurements compared with proxy data whose the resolution is 200 years. If we smooth out the current data over the last two centuries you'd be lucky to see ½ degree per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century). And let's not forget the Dansgaard–Oeschger events. The Dansgaard–Oeschger events were global (Dima et al, 2018). One about 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8°C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. So shall we say a rate of change about 20°C per century. If that happened now you'd be foaming. But life carried on.

  371. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see. As the oceans warm they will be able to spread away from the equator. Their range will expand. There is no climate crisis.

  374. Get it right, Guenther. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  375. Heat waves have not been increasing in intensity or frequency in the United States, which has by far the best meteorological data both spatially and temporally. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current.

  376. Explain this: There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend.

  377. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution.

So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  384. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data).

  385. 4:28 there have been periods of increasing mass of the Greenland ice cap in the 1940's, 70's, 80's and 90's. (Remember CO2 was rising all the time.) The Greenland ice sheet is thought to contribute 0.7mm/yr to sea-level rise, so 54mm by 2100 (just over 2 inches). That sounds small because it is pitifully small. Also an accounting error. More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere (14% of total human emissions). The average annual loss is 0.005% of the total mass (around 3 million gigatonnes). That's neglible. Come back in 20,000 years.

  388. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, and that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021). Intergovernmental Panel on Climate Change (IPCC) AR6 report, Chapter 11,"Weather and Climate Extreme Events in Changing Climate" concludes that changes in the frequency and intensity of most severe weather events (with corresponding intense rainfall) have not been detected nor can they be attributed to human caused climate change. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022 (AIMS) despite repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years.

No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There is no climate crisis.

  392. In the past few months, the World's Sea Surface Temperature (SST) has declined by 0.5°C so that it has returned to the temperature in December 2015 (Daily Sea Surface Temperature World 60°N-60°S 0-360°E NOAA OISST V2.1 dataset available on the ClimateReanalyzer website). The recent off trend temperature rise began before El Niño and was not predicted by climate scientists. The size of the temperature rise was not predicted by climate scientists. The rapid cooling of the ocean back down 2015 levels before the commencement of the next La Niña was not predicted. The top few meters of the ocean store as much heat as Earth's entire atmosphere. If the heat energy content of the World's oceans has increased by 400ZJ since 1960, and the atmosphere has absorbed about ¹/100 th that amount, there is no way an increase of 100ppm of CO2 into the atmosphere has forced that much heat into the ocean. The atmosphere does not hold enough energy, plus infrared radiation cannot penetrate the ocean surfaces beyond a few millimeters (small fractions of an inch) so increasing atmospheric CO2 cannot be an explanation of ocean warming It is not possible for the energy in the atmosphere to affect the ocean temperature changes seen recently or in the long term. In fact the atmosphere is not trapping more energy as the "greenhouse gas" CO2 increases, but the atmosphere is emitting increasing amounts of energy into space as longwave radiation. This is contrary to the idea of man-made global warming. Nearly all of the energy the ocean receives comes directly from sunlight. The relationship between the global surface air temperature (HadCRUT3) and the tropical sea surface temperature (NOAA) is that quite often a change in sea surface temperature appears to be initiated 1-3 months before the corresponding change in surface air temperature. In such cases, the temperature in the lower atmosphere appears to be controlled by change in sea surface temperatures, and not the other way around. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in Absorbed Solar Radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with Total Solar Irradiance (how shiny the Sun is), which reached an all time record-breaking high in 2023 and 2024 as confirmed by satellite measurement (SORCE and TSIS). 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024).

  393. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable

  394. There's lots of data out there on changes to Greenland's ice. If you need something specific, can I refer you to a paper published through ESSD? It is entitled "Greenland ice sheet mass balance from 1840 through next week." (Mankoff et al., 2021). Catchy, don't you think? If you examine Fig.2 on page 5, you will see there would be no correlation with the exponential increase in the concentration of carbon dioxide (280ppm to 420ppm) and the change in the annual Mass Balance Sum shown in the paper. Indeed there have been periods of increasing mass of the Greenland ice cap in the 1940's, 70's, 80's and 90's. (Remember CO2 was rising all the time.) More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere. The average annual loss is 0.005% of the total mass. That's neglible. Come back in 20,000 years.

  395. *The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature.

As I pointed out in a previous comment, as regards the Medieval Warm Period, there are a large number of scientific research papers which confirm my point of view. I would not hold it otherwise. They span the Earth's continents and cover the Northern and Southern Hemispheres.

  399. Weather events are not climate. The severity of individual weather events cannot be attributed to factors implicated in man-made climate change. One cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  400. No. Cold weather kills many more people in all regions of the world. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.

More fake predictions by scientists: 1958 the Arctic Ocean will be Ice free in one generation. 1967 there will be global famine. 1970 there will be an ice age in the 21st century. 1970 Oceans will be dead in less than a decade. 1971 50 years away from an ice age. 1972 glacial temperatures within a century. 1974 satellites show ice age coming fast. 1978 no end to cooling trend. 1979 ice at North Pole will melt in one lifetime. 1982 environmental catastrophe by 2000. 1988 Maldives underwater in 30 years. 1989 entire nations underwater by 2000. 2000 snowfall has become a thing of the past. 2004 UK climate will become Siberian. Cities will sink into the ocean. 2006 10 years until a point of no return. 2007 if no action 2012 will be too late. Also 2007 Arctic ice free 2010, or 2015, or 2013, or 5 years take your pick. 2008 the Arctic ice sheet would melt away. Also 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 Arctic ice free in 2014. 2012 snow will be gone by 2020. 2013 Methane catastrophe in 2 years because of ice free Arctic. 2018 zero chance of permanent ice in Arctic by 2022. Also 2018 humans to go extinct by 2023 from climate change. 2022 End of Snow predicted.

  403. This is a terrible piece of climate propaganda. Notice how the scale used on both the graph and the bar charts are distorted to make the deaths from heat look bigger when in fact they are far smaller. Atrocious. Climate change actually saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022)! There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.

  405. The Greenland Ice Sheet contains about 2.9 million cubic kilometers of ice (NSIDC). Using the formula M=Vd (and assuming density of glacier ice 0.9167 Gt/km³), the mass of GrIS is approximately 2.7 million Gt. If we use the figure of annual loss of 270 Gt, we get 0.01%, or 10,000 years, so around 12,024 AD. The problem is the average figure of 270 Gt (NASA data 2002-2023, 0.8mm/year sea-level rise, so a non-problem). That average value and the data range used gives no understanding of the changes taking place. Prior to 2000 GrIS was not losing mass. From 2002 to 2012 mass loss accelerated, then from 2012 to the present mass loss trend decelerated (85 Gt, 2021). The changes aren't linear they are sinusoidal and are related to the North Atlantic Oscillation, not the the concentration of CO2 in the atmosphere.

  406. There is no climate crisis. The Earth was warmer in the recent and distant past. It also warmed faster in the past. The extra CO2 in the atmosphere has greened the Earth by 15% in the last 20 years (NASA data). This is truly positive but never discussed. Oh and the models are now agreed to run 'hot' i.e. they don't make worthwhile predictions.

  407. ​ @PremierCCGuyMMXVI And what effects of climate change would that be? The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  408. windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021).

  409. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There is no climate crisis.

No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). Take bird species: 11,195 have been counted (not estimated). All of these have been assessed by the IUCN. They catalogued 4 bird species became extinct over the course of 28 years between 1988 and 2016. That's 1.4 per decade or an annual extinction rate of 0.001%. Also the proportion of species assessed as threatened by the IUCN has declined rapidly over time, from 65% in 2000 (11,000 out of 17,000) to 28% in 2024 (46,000 out of 166,000). This increasingly positive outcome of their species assessments is only accelerating as time passes. Using IUCN data on assessed species- Amphibian species extinct 0.009% per decade. Mammals 0.029% per decade. Reptiles 0.006% per decade. Fish 0.006% per decade. Insects 0.009% per decade. There is no climate crisis.

  411. The retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). In Alaska's Glacier Bay the melt rate from 1780 to 1880 was much greater than the melt rate from 1880 to the present. There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  412. The famine in the Horn of Africa is endemic not because of climatic factors but because of bad governance and poverty. If you compare these regions to the Gulf States, the climate of the Gulf is similar, although even drier, but the latter have a much higher standard of living due their wealth of fossil fuels and better social organisation. What the Horn of Africa needs is a good dose of reliable energy from fossil fuels to raise their living standards.

  413. Another climate propaganda video from Auntie Beeb. There is nothing abnormal about Portugal's wildfires this year. The weekly burn area is average. And about one-sixth of the record. Cumulative weekly burn area is below average. Weekly CO2 emissions are way below average. The weekly number of fires is way below average. All of this information is readily available on the EFFIS website. This video and report isn't journalism. It is a tissue of lies. It's propaganda. It's political.

  414. This is bad weather. This is bad governance and poverty. If the Arctic is warming faster than the rest of the planet, shouldn't the temperature gradient between it and the tropics be reduced, thus reducing extreme weather?

  415. More deliciously propaganda from Channel 4. Yum. There is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling with little change in trend around the Equator (NOAA-STARv5 TLT & TMT 1979-2023). Overall the Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade. There is no objective observational evidence that we are living through a global climate crisis. None. Zero.

  416. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in Absorbed Solar Radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with Total Solar Irradiance (how shiny the Sun is), which reached an all time record-breaking high in 2023 and 2024 as confirmed by satellite measurement (SORCE and TSIS). 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere.

  420. This is the data: Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  422. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

  423. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating nor decelerating. The trend is linear. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  424. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The most recent rise stopped in August 2023, and has been declining since (NOAA SST v5 monthly). The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  425. As regards the belief in weather event attribution the IPCC states “Scientists cannot answer directly whether a particular event was caused by climate change, as extremes do occur naturally, and any specific weather and climate event is the result of a complex mix of human and natural factors. Instead, scientists quantify the relative importance of human and natural influences on the magnitude and/or probability of specific extreme weather events.” It is not possible to attribute whether an individual heatwave, drought or a flood, or any climate event, extreme or otherwise is due to human factors. People are fooled into believing it is, thanks to the magic of attribution science. One cannot prove that changes in the climate are man-made, but in tactical attribution science it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs (greenhouse gases) are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science. It's wishful thinking often expounded for legal or political purposes as WWA’s (World Weather Attribution) chief scientist, Friederike Otto, freely admits, “Unlike every other branch of climate science or science in general, event attribution was actually originally suggested with the courts in mind.”

  426. The Arctic minimum summer sea ice trend is zero for the past 18 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 2024 4.28 Plot the trend line for this data and it will be flat. ZERO net change in 18 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). They also noted "the Arctic temperature was higher in the 1930s–40s than in recent decades, and hence a trend calculated for the period 1920 to the present actually shows cooling." Zhang (2021) showed there was no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Including more recent satellite data from Cryosat-2 (2010-2023)reveals the Arctic ice volume minimum (Oct-Nov) is increasing at 56km³/yr (Kacimi and Kwok, 2024). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004 average) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), an El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  428. @blurgle9185  If you have some reputable sources to support your argument I would be interested to research them. However, the strange thing is the Earth is getting greener, so potentially there is more biomass to burn, but it is burning less. Also humans are becoming very efficient at producing more and more food from the same amount of farmland. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%, but Land used for cereal hardly increased (Data from World Bank, FAO/UN). So basically, although our species does have a disproportionate effect on the planet, there is no climate catastrophe that's allowing wildfires to rage out of control.

Unfortunately, one cannot prove that changes in the climate are man-made, but here it is presented as a fact.

  432. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  433. Utter nonsense. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating or decelerating. The trend is linear. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  435. This video obscures the truth. Go back to the source, the Norwegian Meteorological Office (Seklima), to try to get to the bottom of this. I suggest everyone check out their data. Ny-ålesund data for maximum annual temperatures shows no trend since records began in 1969. It has not got hotter. However, the minimum annual temperatures has increased, so the winters have become milder (but still extremely cold). The increase in the annual minimum temperature occurred over 20 years, but this trend stopped around 2006. To find a longer term view on Svalbard you need to look up other weather stations, for example Longyearbyen + Svalbard Lufthavn. Looking at say 1950 to the present shows no trend in the maximum temperatures. The minima dropped quite considerably from the later 50s. The 60s and 70s had an intensely cold trend of minima. It then warmed in the 80s/90s and from 2005 levelled off. So overall the swings in temperature on Svalbard during the year have become less extreme. Very roughly, it hasn't got hotter, but the winters, which got very much colder, became less cold, now they have stopped getting less cold since about 2005. Svalbard's climate became milder, less extreme than compared to the 60s and 70s, but not hotter. That process of amelioration has stopped. These changes are uncorrelated to the level of CO2 in the atmosphere.

  437. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". A study of Antarctic ice shelves from 1980 to 2021 (Banwell et al, 2023) showed meltwater volume dropped with "decreasing trend in both annual melt days and meltwater production volume over the 41 years.” "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high. Antarctica contributes 0.36mm to sea-level rise per year (that's essentially nothing as well). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. That ice is here to stay.

Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! As an example of good news, Climate Change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022).

  441. @8fledermaus8  Wildfire: Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US so far in 2023 including Maui is 3rd lowest on record. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

It doesn't matter what I am. You are attempting to divert yourself and others from the facts, the objective reality, probably because it does not sit well with your own belief system regarding the world. You cannot argue against the facts so you insult me in the hope of downgrading the worth of those facts in order that you do not have to accept the truth, and damage your own internal narrative as that would be too uncomfortable for you.

  445. @8fledermaus8  The correlation between temperature and CO2 if examined closely shows CO2 followed temperature with a lag of about 800 years at the transition from the last ice age to the current interglacial. I.e. the ice core evidence for Pleistocene/Holocene shows temperature rise caused CO2 to rise not the other way around probably due to outgassing from a warmer ocean. In fact, it gets more complicated, when comparing temperature data from Greenland for the Holocene (GISP 2) with CO2 (EPICA ice dome c) the correlation from about 3,500 years ago onwards appears to be negative. The temperature fell first, then CO2 went up. So over time the correlation between temperature and CO2 is very poor.

  448. There are no actual global observational data on changes to permafrost. The Li et al 2022 paper 'Changes in permafrost extent and active layer thickness in the Northern Hemisphere from 1969 to 2018' states "The temporal change characteristics of the permafrost extent and ALT [active layer thickness] for the NH [Northern Hemisphere] have not been studied." These things have only been poorly estimated or modelled. The aforementioned paper modelled permafrost extent decreased from 23.25 × 10⁶km2 (average from 1969 to 1973) to 21.64 × 10⁶km2 (average from 2014 to 2018), with a linear rate of −0.023 × 10⁶ km2/a. That's an annual change of 0.099 of a percent. That's negligible and could just as easily be increasing due to the uncertainty in the modelling. Out of global estimated emissions of methane of around 600 Tg CH4 per year, the best estimate of emissions from pan-Arctic permafrost is 1 Tg CH4 per year (Elder et al, 2021), so that's less than 0.17%. It's almost nothing.

  452. @time_warriors  The fact that such a small number of British could sit atop a system that governed such a huge mass of humanity is a credit to British history. It is a demonstration of the energy and dynamism of the British nation at that time, and totally in keeping with the ways in which pre-industrial societies were organised. Of course it was a pyramid, but it was one overlaid on an Indian society in which it had always been thought proper that a member of higher caste could exploit, abuse and even murder the members of a lower caste as the whim took them. Before the British, the Zamindars were warlords who would rapaciously exploit their own holdings whilst raiding and degrading the lands of other Zamindars. The British pacified them, and brought the rule of law. Besides which all this was just an evolution of the jagirdar system used by the Mughals and the Sultanate of Delhi before that. These agrarian parasites were already there. But they were Indian, not British. This Indian elite creamed off 15% of the national income under the Mughals, and after the latter's collapse, between 1750 and 1810, the despotic indigenous elite extracted upto 50% of production so they could indulge in warfare. Despicable. The British stopped all that, and at the height of the Raj, the Zamindars only took 3% for themselves. The idea that the British somehow drained the life out of India is without statistical foundation. The colonial government was a very small part of economy, and any monies sent out of the country were easily offset by India's trade surplus. India had attracted £380 million in British capital by 1913, £23 billion in today’s money. But Home charges in 1913, the so-called drain from India to Britain, were only £ 11 million, tiny by comparison. The introduction of Peace, the Rule of Law, Property Rights, Modern Education based on Enlightenment Ideals, economic entrepreneurship and ultimately Democracy, were of huge benefit to Indians. The British way of doing things was just better and that's why they won India. When the British decided to quit India, the country didn't magically blossom into some Hindustani utopia freed from the yoke of those nasty Brits. No. It lapsed into 50 years of 'Licence Raj' riddled with corruption and inefficiency.

Indian society was one in which it had always been thought proper that a member of higher caste could exploit, abuse and even murder the members of a lower caste as the whim took them. Before the British, the Zamindars were warlords who would rapaciously exploit their own holdings whilst raiding and degrading the lands of other Zamindars. The British pacified them, and brought the rule of law. Besides which all this was just an evolution of the jagirdar system used by the Mughals and the Sultanate of Delhi before that. These agrarian parasites were already there. But they were Indian, not British. This Indian elite creamed off 15% of the national income under the Mughals, and after the latter's collapse, between 1750 and 1810, the despotic indigenous elite extracted upto 50% of production so they could indulge in warfare. Despicable. The British stopped all that, and at the height of the Raj, the Zamindars only took 3% for themselves.

  454. Since 1900 the global temperature has increased by 1.3°C. In that time humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  457. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  459. There are no actual global observational data on changes to permafrost. The Li et al 2022 paper 'Changes in permafrost extent and active layer thickness in the Northern Hemisphere from 1969 to 2018' states "The temporal change characteristics of the permafrost extent and ALT [active layer thickness] for the NH [Northern Hemisphere] have not been studied." These things have only been poorly estimated or modelled. The aforementioned paper modelled permafrost extent decreased from 23.25 × 10⁶km2 (average from 1969 to 1973) to 21.64 × 10⁶km2 (average from 2014 to 2018), with a linear rate of −0.023 × 10⁶ km2/a. That's an annual change of 0.099 of a percent. That's negligible and could just as easily be increasing due to the uncertainty in the modelling. Out of global estimated emissions of methane of around 600 Tg CH4 per year, the best estimate of emissions from pan-Arctic permafrost is 1 Tg CH4 per year (Elder et al, 2021), so that's less than 0.17%. It's almost nothing.

  460. Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. Banana production has doubled in 20 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). 2023 was another record cereal crop. Increases in cereal production since 1961: Africa +384%, Asia +348%, Australia +458%, Europe +110%, North America +184%, South America +547%. Percentage increase in production in all regions also exceeded the percentage increase in population. Global and regional food security is improving. 2024-2025 will see another record high production of wheat, soybeans and rice. Compared with a decade ago, the world will harvest in 2024-25 about 10% more wheat, about 15% more corn, nearly 30% more soybeans, and about 10% more rice. Global food supply (kcal per capita per day) has increased from 2181kcal in 1961 to a record 2959kcal in 2021.

  461. Not this. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This is decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8.

  464. ​@davidsalo8397 Check this out dummkopf: "The most robust global changes in climate extremes are found in yearly values of heatwaves (number of days, maximum duration and cumulated heat), while global trends in heatwave intensity are not significant. Daily precipitation intensity and extreme precipitation frequency are stationary in the main part of the weather stations. Trend analysis of the time series of tropical cyclones show a substantial temporal invariance and the same is true for tornadoes in the USA. At the same time, the impact of warming on surface wind speed remains unclear. The analysis is then extended to some global response indicators of extreme meteorological events, namely natural disasters, floods, droughts, ecosystem productivity and yields of the four main crops (maize, rice, soybean and wheat). None of these response indicators show a clear positive trend of extreme events. In conclusion on the basis of observational data, the climate crisis that, according to many sources, we are experiencing today, is not evident yet." (Alimonti, et al. 2022. The European Physical Journal Plus, Volume 137.)

  466. The IPCC do not believe the melting of the arctic permafrost will cause a tipping point in the release of warming methane gas “the carbon released to the atmosphere from thawing permafrost is projected to be restricted to 0.09–0.19 Gt C yr–1 at 2°C of global warming and to 0.08–0.16 Gt C yr–1 at 1.5°C, which does not indicate a tipping point”.

  467. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity.

  468. This is a propaganda video. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

  469. There are more trees not less! The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature.

  470. 4:21 This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  487. Then he gets back on his private jet and flies back to his beachside mansion. You are a fool if you listen to this geriatric. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  488. @Cloughjordan23  You make it sound like they had a cunning plan, but they actually, physically ran away as fast as their little legs would carry them, only to glance in fear over their rainbow badged shoulders as they put themselves to flight. They could have walked away. The only person they arrested on the night was an elderly white woman who wasn't rioting and hadn't committed any crime. They locked her in the cells all night. Outrageous.

  489. Yes, China is the largest producer of turbines and panels. The reason is you need the cheap energy from burning coal to do that. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. The UK is responsible for less than 1% of global CO2 emissions.

  490. Silly scary nonsense. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920. Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, and that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021). What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). Global temperatures maxed out in 2016 and have been lower ever since (UAH v6 global satellite data). 500 billion tonnes of emissions in that time, and no warming. There is no climate crisis.

  491. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones.

  492. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in Absorbed Solar Radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with Total Solar Irradiance (how shiny the Sun is), which reached an all time record-breaking high in 2023 and 2024 as confirmed by satellite measurement (SORCE and TSIS). 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024)

  496. More propaganda from Auntie Beeb. The truth is Climate Change, i.e. warming, saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). There are over 5 million excess deaths per annum globally due to abnormal temperatures, so says the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. That's 4½ million souls died of the cold. This applied globally including in the hottest continent, Africa. So, in a world with increasingly warmer temperatures, there will be less excess death. Warming is good not bad. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.

  501. As regards regards the rate of temperature change, the warming in the current modern era has been neither consistent nor rapid both temporally and spatially. The climate of the US in the 20th century is good example of this. The US has by far the best actual temperature recordings for this period with very little coverage elsewhere outside of Europe. Data from NOAA (2021) shows uneven warming focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day. All of this demonstrates to my mind that the climate has a strong internal variability without the requirement for any external anthropogenic forcing. Globally satellite data shows how variable the Earth's climate is with changes up or down of more than 1°C occurring from one year to the next. However, overall the Earth's ecosystems are resilient to these fluctuations, as most species are eurytopic enough to survive these changes.

  502. The Earth's changing climate has extremely low sensitivity to CO2. This is supported by a huge body of scientific evidence. What follows is a list of approximately 50 scientific research papers confirming this. There are at least another 100 that I know of. Smirnov, 2018 (2X CO2 = 0.4°C) (2X AnthroCO2 = 0.02°C).

Harde, 2017 (2XCO2 = 0.7°C ). Khmelinskii and Woodcock, 2023 2XCO2 = 0.015°C. Schuurmans, 1983 (2XCO2 = ~0.3°C ). Kissin, 2015 (2XCO2 = ~0.6°C). Ollila (2019) (2XCO2 = ~0.6°C).

There is no evidence of a climate crisis, and CO2 is certainly not the control knob for the climate.

  503. This is boring. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  504. Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr; Newlyn, UK 1.94mm/yr. Jevrejeva, et al (2014) estimated 2 mm/year (± 0.3), and Church and White (2006) estimated 1.7mm/year (± 0.3). So that's a total rise of between 126 and 151mm (less than 6 inches) from 2024 to the end of the century. Or try PSMSL data: Kwajalein (Marshall Islands) 1.95mm/yr; Maldives (Indian Ocean) 3.21mm/yr; Lautoka (Fiji Islands, Pacific Ocean) 3.50mm/yr; Port Elisabeth (South Africa) 2.34mm/yr. Remember, all linear over many decades, or more than a century. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked for each set of satellite data (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a rise of 3.3mm per year. That's the same as two stacked penny coins. There is no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  505. @JacktheSmack  You probably want to start in the 1960s. That's fine. I understand why. Can I recommend you pop over to the website "our world in data" and go to the page "Annual Heat Wave Index in the United States"? Don't worry, it sources its data from NOAA. Now you should see a red spikey thing - that's a graph. You'll enjoy moving the blue slider along the bottom. Notice that all the tallest spikes are in the 1930s. The very tallest (1936) is 1.3 on the severity index. The most recent readings are around 0.1, so that's a factor of 13. Imagine if you had a heatwave like that now. People like you would be screaming and dropping from apoplexy. How did your ancestors survive without air-con (or global warming!)? Anyway, there's only one, just one, place on this graph you can start and show an increasing trend. That's the 1960s (0.05). And that's why you've chosen it (or it was chosen for you). Now that is a mighty fine cherry. Another lesson to draw from this is that there is zero positive correlation between the concentration of CO2 in the atmosphere and heatwaves.

  507.  @astronautical1082  How about admitting we don't understand the Earth’s climate system? The recent off trend temperature rise began before El Niño and was not predicted by climate scientists. The size of the temperature rise was not predicted by climate scientists. The rapid cooling of the ocean back down 2015 levels before the commencement of the next La Niña was not predicted.
    2
  508. @astronautical1082  How about realising the recent decadal temperature rise is due a reduction in cloud cover? How about we are not certain what causes this change in cloud cover? How about the temperature rise is due an increase in absorbed solar radiation? How about an awareness that increasing CO2 should reduce the outgoing longwave radiation but that has increased dramatically?
    2
  509. @astronautical1082  So what's the problem?
    2
  510. @astronautical1082  So there is supposed rapid warming over the last century but that's not a fair comparison with previous ages. That's instrumental - which has its own reliability issues due to it poor spatial and temporally collection (until the advent of satellites) - with annual instrumental measurements compared with proxy data with the latter's resolution intervals often at 200 years. If we smooth out the current data over the last two centuries you'd be lucky to see ½ degree per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century). And let's not forget the Dansgaard–Oeschger events. The Dansgaard–Oeschger events were global (Dima et al, 2018). One about 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8°C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. So shall we say a rate of change about 20°C per century? If that happened now people would assume the Rapture was imminent. But life carried on. Globally satellite data shows how variable the Earth's climate is with changes up or down of more than 1°C occurring from one year to the next. However, overall the Earth's ecosystems are resilient to these fluctuations, as most species are eurytopic enough to survive these changes. This is a scare story about things you cannot see. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 908 known lost species for 2.1 million known species in 500 years (IUCN Red List), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). Take bird species: 11,195 have been counted (not estimated). All of these have been assessed by the IUCN. They catalogued 4 bird species became extinct over the course of 28 years between 1988 and 2016. That's 1.4 per decade or an annual extinction rate of 0.001%. Also the proportion of species assessed as threatened by the IUCN has declined rapidly over time, from 65% in 2000 (11,000 out of 17,000) to 28% in 2024 (46,000 out of 166,000). This increasingly positive outcome of their species assessments is only accelerating as time passes. Using IUCN data on assessed species- Amphibian species extinct 0.009% per decade. Mammals 0.029% per decade. Reptiles 0.006% per decade. Fish 0.006% per decade. Insects 0.009% per decade. There is no climate crisis.

  511. ​ @JJRM8 The Arctic minimum summer sea ice trend is zero for the past 18 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 2024 4.28 Plot the trend line for this data and it will be flat. ZERO net change in 18 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). They also noted "the Arctic temperature was higher in the 1930s–40s than in recent decades, and hence a trend calculated for the period 1920 to the present actually shows cooling." Zhang (2021) showed there was no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Including more recent satellite data from Cryosat-2 (2010-2023)reveals the Arctic ice volume minimum (Oct-Nov) is increasing at 56km³/yr (Kacimi and Kwok, 2024). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), an El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  512. The retreat of glaciers such as those in Himalayas began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). In Alaska's Glacier Bay the melt rate from 1780 to 1880 was much greater than the melt rate from 1880 to the present. There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  513. Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US so far in 2023 including Maui is 3rd lowest on record. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  514. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence, so 50-50), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence, so 50-50. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising!

  515. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones.

  516. This is a propaganda video. In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". What the BBC are reporting is an unusual weather event dressed up as the end of the world. Antarctic sea ice was at a record maximum in 2015. The BBC didn't report that as part of a climate crisis. And why don't the BBC report on the Arctic? Because there's been no warming there this summer. Summer 2023 is one of the coldest in decades in the Arctic, and May 2023 was the coldest on record there. The Greenland ice sheet surface mass balance (SMB) for the past 11 months is a massive 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). No, Auntie Beeb isn't going to report that. In addition, the extent of ice on the planet has no correlation to the concentration of carbon dioxide in the atmosphere.

  517. There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017.

  518. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There is no climate crisis.

  519. There is no objective observational evidence that we are living in a global climate crisis. Just refer to the following if you come across a climate alarmist: The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones. That will either shut the net zero nut up or start them foaming at the mouth. Either is fine.

  520. This climate report is propaganda. The CSI (Climate Shift Index) is based on the relative frequency of daily temperatures in the current climate and in a world without human-caused climate change. Unfortunately, one cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no extra CO2 had been added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  521. @birbatron987  You still haven't explained how I'm misinformed. And the climate isn't getting worse. Quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" s11.5.4, p1569. So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" s11.6.4.5, p1579. So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" s11.7.1.2, p1585. So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" s11.7.2.1, p1592 So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" s11.7.3.2, p1595. "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" s11.7.4, p1598. That's between 60°N and 60°S, so pretty much where everyone lives.

  522. @rashomon66  Even the biased UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Mean precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones. If there's a dichotomy between different parts of the report, you'll have to take that up with the IPCC.

  524. This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures, when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  525. So it was never then. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.

  528. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The most recent rise stopped in August 2023, and has been declining since (NOAA SST v5 monthly). The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  529. Heat waves have not been increasing in intensity or frequency in the United States, which has by far the best meteorological data both spatially and temporally. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. The percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) was at a record low (1895-2023) of 51% in 2023. The record high was 1931 at 93%. The trend has been consistently downwards since the thirties. The climate crisis was 90 years ago. You missed it.

  530. If you took away El Niño, a record increase in Total Solar Irradiance, and the Tonga eruption (all natural events) there would have been nothing to see in 2023. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Total solar irradiance: satellite data from 1979 onwards shows June 2023 at an all time high in over 40 years of measurements (ncei.noaa). There were lows below 1361 W/m² in 2019 to current highs over 1362 W/m² in June (using a lowess curve, which also shows the fastest rate of increase during this recent period). So we are looking at a change of around 1½ Watts over the course of 5 years (the maximum difference is 2.1W/m²). That may not sound much but it exceeds the increase in the Earth's Energy Imbalance (0.9 W/m², 2018 - 1.97 W/m², 2023) (NASA CERES EBAF TOA). Overall the current increase in solar irradiance should give a direct global heating effect of +0.1°C, with an indirect effect of +0.2°C (after Schmutz, 2021). This increase in solar irradiance is related to an earlier than expected increase in sunspot activity, which has not yet reached its zenith, and that may not happen for several years (Royal Observatory Belgium), so further heating from this cause can be expected.

  532. Pakistan Floods: area flooded 8%, much of this short term. 2010 floods were worse. Both associated with La Niña phase during a Northern Hemisphere summer - a natural phenomenon. There is no connection to the concentration of carbon dioxide in the atmosphere. August 1961 was wetter. For Pakistan's annual rainfall totals the 7-year moving average has barely changed since the 1980s, fluctuating up and down, but with no long term trend. Pakistan has endured major floods long before any significant rise in CO2. Since 1850 Pakistan has experienced 7 major droughts and 6 major floods. Since 1880 there is no trend in excess rainfall or drought conditions over the greater Indian region. I might add the people of Pakistan are also suffering from poverty, bad governance and uncontrolled population growth. In addition in the immediate future they will suffer from the perverse environmental policies of Developed countries that have decided to stop extracting their own energy resources, but will consume the rest of the world's, outbidding poorer countries, like Pakistan, consigning them to darkness and further poverty.

  533. @ProctorsGamble  Severely factors are affecting the Panama Canal. It is the dry season and this has been exasperated by El Niño (both natural events). However there is the management of the lakes that supply water and the canal itself. Also the population has increased by a factor of 5 since 1950, and personal income, and along with it water consumption has ballooned. The water supply comes from the very same lakes that supply the canal.

  535. Good news. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  536. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.

  537. Weather events are not climate. Anecdotes are not science. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis...there isn't even any evidence for it.

  538. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  539. This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? These numerical models produce ocean circulations that are far from what we actually observe. These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents. The most recent research into the AMOC confirms it is not weakening. From a 2024 paper by Terhaar et al published in Nature Communications "Based on the here identified relationship and observation-based estimates of the past air-sea heatflux in the North Atlantic from reanalysis products, the decadal averaged AMOC at 26.5°N has not weakened from 1963 to 2017". So not even close to a tipping point or collapse. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures, when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  542. When it comes to tipping points this is what the IPCC (Special Report on implications of 1.5C or more warming, Chapter 3) says:“there is little evidence for a tipping point in the transition from perennial to seasonal ice cover. No evidence has been found for irreversibility or tipping points, suggesting that year-round sea ice will return given a suitable climate”. The IPCC also do not believe the melting of the arctic permafrost will cause a tipping point in the release of warming methane gas “the carbon released to the atmosphere from thawing permafrost is projected to be restricted to 0.09–0.19 Gt C yr–1 at 2°C of global warming and to 0.08–0.16 Gt C yr–1 at 1.5°C, which does not indicate a tipping point”. The Earth's climate is a multi input thermodynamic system and will conform to Le Chatelier's Principle.

  543. The oil companies didn't know what was going to happen in the 1970's. Nobody did, and frankly nobody does. They had done some scientific research and had constructed some models, which they correctly treated with caution. As everyone should do, as all the subsequent models have been shown not to work, and vary enormously in their output. The problem is people believe these climate models to be Truth Machines. They are not.

  544. When it comes to fires, Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? And the fires of 2023 seem to have been largely started by arsonists. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million, the lowest since 1998 (NIFC), and 3% of the burn in the 1900s Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there was nothing unusual about 2023 summer's fire season in Europe (look it up on the EFFIS website). The burned area was lower than 2021, 2022, and most of the 80's and 90's. In Portugal, Spain, France, Italy and Greece 2023 was only the 20th highest in the modern satellite burnt acreage record going back to 1980. Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  545. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  546. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating or decelerating. The trend is linear. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  547. In the past few months, the World's Sea Surface Temperature (SST) has declined by 0.5°C so that it has returned to the temperature in December 2015. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in absorbed solar radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with total solar irradiance, which reached an all time record-breaking high in 2023 as confirmed by satellite measurement. 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024)

  548. No. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes."

  549. Yet another climate propaganda video. NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades in the Arctic, and May 2023 was the coldest on record there. The Greenland surface mass balance (SMB) for the past 11 months is a massive but very normal 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking.

  550. Total propaganda. There is no climate emergency. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  551. It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020), 2°C above present, also Wang et al, 2013, showing the change was at least hemispheric, and Minoan Warm Periods (Lécuyer, 2018, 4°C above present, links Mediterranean to Greenland Ice so at least hemispheric). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer), far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable. Maybe it was those pesky Neanderthals driving around in their SUVs. That one's been all over the news but if you want a citation I think it was in the 7th December 2022 issue of Nature. The original research was done by some Danish chappy. If you want some really rapid warming look at the CET (Central England Temperature) Instrumental Record between 1690 and 1730 (3°C increase). That might not be reliable enough for you though. Why not try the Dansgaard–Oeschger events? The Dansgaard–Oeschger events were global (Dima et al, 2018).About 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8 °C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. Some researchers believe the Medieval Warm Period was one of these, but I'm not convinced. However, I can provide upwards of 100 citations of science papers that together show the Medieval Warm Period was qualitatively and quantitatively warmer than the current warming, and that it was global in nature, focused around the year 1000. The current warming began around 1700 prior to any large scale combustion of fossil fuels. Also the warming has been small (1°C) and appears to have been largely beneficial. It has not been smooth, for example there was a period of cooling during the 50s, 60s and 70s (NOAA). When many scientists believed the next ice age had begun. Current warming is smaller than predicted by all models (actual is 0.13°C per decade since 1979, UAH v6) so around ½°C for the past 40 years but no overall warming over the past 8. This will result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°. Please be aware that the IPCC's (Scenario A) modelled predictions are junk. Back in 1990 they predicted a warming of 0.30-0.34°C per decade. Of course we've only had 0.13°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it. But there is still no crisis just an unexciting set of observations. As regards the climate models that predict the 4°C warming of our nightmares, even the IPCC believes they are running 'too hot'. They did not correctly predict the current low level of warming, and are not able to mimic past climates. They are junk. Current warming from global satellite data (UAH v6) from 1979 shows warming at a rate of 0.13°C per decade. As there's less than 80 years left in this century, warming will have to accelerate dramatically to nearly 0.4°C a decade. This is unlikely. At the current rate by 2100, a warming of 1°C will have occurred. Hardly noticeable. Barely an inconvenience

  552. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  553. No. NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades.
    2
  554. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  555. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  556. @kimlibera663  Don't let the alarmists get you down. In the past few months, the World's Sea Surface Temperature (SST) has declined by 0.5°C so that it has returned to the temperature in December 2015 (Daily Sea Surface Temperature World 60°N-60°S 0-360°E NOAA OISST V2.1 dataset available on the ClimateReanalyzer website). The recent off trend temperature rise began before El Niño and was not predicted by climate scientists. The size of the temperature rise was not predicted by climate scientists. The rapid cooling of the ocean back down 2015 levels before the commencement of the next La Niña was not predicted. If the heat energy content of the World's oceans has increased by 400ZJ since 1960, and the atmosphere has absorbed about ¹/100 th that amount, there is no way an increase of 100ppm of CO2 into the atmosphere has forced that much heat into the ocean. The atmosphere does not hold enough energy. It is not possible for the energy in the atmosphere to affect the ocean temperature changes seen recently or in the long term. In fact the atmosphere is not trapping more energy as the "greenhouse gas" CO2 increases, but the atmosphere is emitting increasing amounts of energy into space as longwave radiation. This is contrary to the idea of man-made global warming. Nearly all of the energy the ocean receives comes directly from sunlight. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in Absorbed Solar Radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with Total Solar Irradiance (how shiny the Sun is), which reached an all time record-breaking high in 2023 and 2024 as confirmed by satellite measurement (SORCE and TSIS). 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024)

  558. Propaganda video. The Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade. Also there is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling.

  559. CH4 is only 0.00019% (1.9 parts per million) of the atmosphere. Both of its narrow absorption bands occur at wavelengths where H2O is already absorbing substantially. Hence, any radiation that CH4 might absorb has already been absorbed by H2O. With the concentration of water vapour in the atmosphere being between 1,000 and 20,000 times greater than CH4, the effects of CH4 are completely masked by H2O.

  561. @JeffreyGoddin  Gas Laws not your thing, or just beyond your ken?

  562. @Skyhawk1480  Oh dear, I hope you're not doing the educating. What you wrote about Jupiter shows a lack of understanding. When you refer to 'surface' there isn't one. Jupiter is a gas giant and may not have a solid surface in the way in which you imagine (like Earth or Venus). The 'surface' you refer to is an astronomical convention. It is the atmospheric point at which in the section of the gas column of Jupiter's troposphere where the pressure is equal to 1bar (i.e. the approximate atmospheric pressure at sea-level on Earth). So not 1000bar. Silly mistake, "and speaks poorly to the state of education you've been exposed to". The Galileo entry probe was dropped into Jupiter's atmosphere in 1995. As it descended it measured the temperature and pressure. 21km above your imaginary surface the pressure was 0.45bar, and the temperature was -145°C. At 1bar it was indeed -110°C. But it continued its descent through the atmosphere for a further 146km to a point where the temperature was +153°C. The pressure had become so great (22 bar) that the probe stopped transmitting. The pressure would increase as you descend deeper through Jupiter's atmosphere. Approximately 3000km below your imaginary surface, the pressure is so great the atmosphere starts behaving as a supercritical fluid. At around 500,000bar of pressure, the temperature is around 5,000°C. At 4,000,000 bar, the temperature should exceed 8,000°C. The temperature and pressure inside Jupiter increase steadily inward. As far as Venus is concerned, the point in its atmosphere where the pressure is 1bar is 53km above the actual hard, rocky surface of the planet. The temperature at that altitude is 20 to 30°C as you might expect from a planet so close to the Sun. To summarise on both planets tropospheric temperature increases with increasing atmospheric pressure. The temperature in their atmospheres at 1bar is related to their distance from the Sun. This relationship also holds true for Earth, Saturn, Neptune, and Uranus (Mercury and Mars do not retain enough of an atmosphere to reach 1bar of pressure). I know it's uncouth but I really do take some pleasure in rude, insulting, ignorant people getting things wrong and it being pointed out to them.

  563. @Skyhawk1480  "Gravitational collapse" leads to an increase in pressure and, hence, of course, an increase in temperature.

  564. @Skyhawk1480  Do you still think Jupiter has a "surface" at 1bar (or even 1000bar) of pressure?

  565. Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr; Newlyn, UK 1.94mm/yr. Jevrejeva, et al (2014) estimated 2 mm/year (± 0.3), and Church and White (2006) estimated 1.7mm/year (± 0.3). So that's a total rise of between 126 and 151mm (less than 6 inches) from 2024 to the end of the century. A paper from Frederikse et al (2018) shows a global trend of 1.5 ± 0.2 mm yr−1 over 1958–2014. That's 6cm by 2050, and 30cm by 2100. Or try PSMSL data: Kwajalein (Marshall Islands) 1.95mm/yr; Maldives (Indian Ocean) 3.21mm/yr; Lautoka (Fiji Islands, Pacific Ocean) 3.50mm/yr; Port Elisabeth (South Africa) 2.34mm/yr. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked for each set of satellite data (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a rise of 3.3mm per year. That's the same as two stacked penny coins. There is no relationship to the increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  568. There is no objective observational evidence that we are living in a global climate crisis.

  570. The increase in the global temperature anomaly this year is due to ENSO, an increase in Total Solar Irradiance, and maybe the Tonga eruption. These are all natural events, totally unaffected by human activity.

The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  572. @parrisgjerde9212  Try these for size: The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Increased CO2 causes this in two ways: it has a direct fertilising effect (the CFE), and it increases drought tolerance by reducing stomata. This greening of the Earth due to CO2 is now "an indisputable fact" (Chen et al, 2024). In fact, 55.15% of those areas greening have been doing so at an accelerated rate since 2001. Since the start of the Industrial Revolution the Earth's primary productivity has increased by more than 30% (Campbell et al, 2017 and Haverd et al, 2020).

  573. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  574. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022 and 2023 (AIMS) despite repeated bleaching. In 2022, AIMS LTMP (long term monitoring programme) found record high coral cover on the Great Barrier Reef of 0.34 (i.e. 34% of the seabed on the coral reefs monitored are covered with coral). Over the past 36 years, cover has varied dramatically, and reached a low point in 2011 of 0.12. There was about twice as much coral in 2022 as in 2011. Since 2016 there has been a rapid rise in cover, despite four bleaching events occurring between 2016 and 2022. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate or to the concentration of carbon dioxide in the atmosphere. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. When it comes to storms destroying coral, who's expecting cyclones to become more frequent and intense. Using data from the JMA (1951-2022), we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years. Climate alarmists don't like this because it refutes all their failed predictions over many many years, so I have no agreement with the latest ones about the wrong type of coral on the brink of being destroyed by imaginary storms. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  579. There are no observations that agree with this craziness. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  580. As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’

  584. This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures, when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  586. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Increased CO2 causes this in two ways: it has a direct fertilising effect (the CFE), and it increases drought tolerance by reducing stomata.

  590. I'm afraid the Antarctic Doomsday glaciers have lost their doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Antarctica is not warming, it's cooling, with the evidence showing it has been doing so for at least 40 years, maybe more than 70 (Singh and Polvani, 2020; Bello et al, 2022; Zhang et al, 2022; Zhu et al, 2021). So no "global" warming, and no polar amplification - at least not at the South Pole. Therefore man-made climate change cannot be causing any change in the melt rate of WAIS including Thwaites. Because, you know, it would have to get warmer for the ice to melt. So if there is an increase in the movement of the ice it is coming from heat below, and that is what research suggests - geothermal flux (Dziadek et al, 2021; Martos et al, 2017). If it is hot rock melting ice, there's nothing we can do about it, of course. Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  591. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021).

  592. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940.

If I ever came across this situation again I would like to think I would speak up immediately. I think what happened could be considered illegal: Section 406 of the 1996 Education Act prohibits the promotion of partisan political views, and any idea that is contentious.

  598. Let's scare people. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably since the 1980's and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years. It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. There is no climate crisis.

So they can't model Convection. So they can't model ocean currents. From a 2024 paper by Terhaar et al published in Nature Communications "Based on the here identified relationship and observation-based estimates of the past air-sea heatflux in the North Atlantic from reanalysis products, the decadal averaged AMOC at 26.5°N has not weakened from 1963 to 2017". So not even close to a tipping point or collapse. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two.

See Figure 8 in the paper).

  600. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve).

  601. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  603. In the past few months, the World's Sea Surface Temperature (SST) has declined by 0.5°C so that it has returned to the temperature in December 2015 (Daily Sea Surface Temperature World 60°N-60°S 0-360°E NOAA OISST V2.1 dataset available on the ClimateReanalyzer website). The recent off trend temperature rise began before El Niño and was not predicted by climate scientists. The size of the temperature rise was not predicted by climate scientists. The rapid cooling of the ocean back down 2015 levels before the commencement of the next La Niña was not predicted. If the heat energy content of the World's oceans has increased by 400ZJ since 1960, and the atmosphere has absorbed about ¹/100 th that amount, there is no way an increase of 100ppm of CO2 into the atmosphere has forced that much heat into the ocean. The atmosphere does not hold enough energy. It is not possible for the energy in the atmosphere to affect the ocean temperature changes seen recently or in the long term. In fact the atmosphere is not trapping more energy as the "greenhouse gas" CO2 increases, but the atmosphere is emitting increasing amounts of energy into space as longwave radiation. This is contrary to the idea of man-made global warming. Nearly all of the energy the ocean receives comes directly from sunlight. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in absorbed solar radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with total solar irradiance, which reached an all time record-breaking high in 2023 as confirmed by satellite measurement. 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024)

  605. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  606. @PremierCCGuyMMXVI  The current warming began around 1700 prior to any large scale combustion of fossil fuels. Also the warming has been small (1°C) and appears to have been largely beneficial. It has not been smooth, for example there was a period of cooling during the 50s, 60s and 70s (NOAA). When many scientists believed the next ice age had begun. Current warming is smaller than predicted by all models (actual is 0.13°C per decade since 1979, UAH v6) so around ½°C for the past 40 years but no overall warming over the past 8. This will result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°.

  609. This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis.   The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents.    From a 2024 paper by Terhaar et al published in Nature Communications "Based on the here identified relationship and observation-based estimates of the past air-sea heatflux in the North Atlantic from reanalysis products, the decadal averaged AMOC at 26.5°N has not weakened from 1963 to 2017". So not even close to a tipping point or collapse.   Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures, when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact.   The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  611. America has by far the best instrumental data, and it shows overall the South East cooled in the last 120 years. Though that sentence doesn't do justice to the climate's variability. Data from NOAA (2021) shows uneven warming in the twentieth century focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West US showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day.

  615. @Mike-zx1kx  "The great thing about scientific knowledge are [you mean 'is'] that you do not have to guess but can refer to accumulated knowledge obtained." This is exactly what I have done in some detail, with numerous references (something you have not done). My data shows there is no calamitous warming taking place in the Arctic at present, and there was nothing in your written meanderings that disproved that. On another point, it may be that your first language is not English, but can you please learn to decline the auxiliary verbs 'to have', 'to be', and 'to do' correctly? For example, it should be "it has" not "it have". Many thanks.

  616. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". A study of Antarctic ice shelves from 1980 to 2021 (Banwell et al, 2023) showed meltwater volume dropped with "decreasing trend in both annual melt days and meltwater production volume over the 41 years.” "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.

  618. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. It will mean increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming huge amounts of copper and other rare metals for the next 25 years. 1.5 billion tonnes of concrete 42 million tonnes of steel (which is going to need 27 million tonnes of coking coal) 1.9 million tonnes of copper 1.3 million tonnes of zinc 184,000 tonnes of manganese 122,000 tonnes of chromium 56,000 tonnes of nickel 54,000 tonnes of other critical minerals. No doubt all of these materials will be ethically sourced using low carbon processes. Nuclear power would require less than ½ of these resources and Coal power around ¹/10th. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  619. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  620. Phoenix's population has expanded exponentially in that time from a few tens of thousands to a few million. This has dramatically increased the Urban Heat Island effect resulting in temperatures 10°F (5°C) higher during the day (Scientific American, 2019). This alone explains the record high temperatures. As I'm sure everyone is aware, Phoenix is in the Sonoran desert, which is characterised by long summers and extremely high temperatures. And that's exactly what's happening. There's nothing unusual or unexpected here. The news story is purposely catatrophising the weather to unnecessarily scare people into changing their way of life. There is no global climate crisis. 2:08

  624. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we could even notice it.

  627. @magesalmanac6424  What can be asserted without evidence can also be dismissed without evidence. However there is plenty of evidence against your assertion. For example: There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%!
    2
  628. There is no "window" so it's not closing rapidly. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  629. Wow! They're trying to press all the buttons. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This is decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  632. @Jc-ms5vv  Warming events in the Cenozoic do not correlate to mass extinction. The Paleocene-Eocene Thermal Maximum PETM (55mya), a time when the Earth warmed rapidly to temperatures far in excess of today's, only resulted in a noticeable extinction of some benthic foraminifera. That was so small of an event it doesn't even show up on a marine extinction intensity chart for the Phanerozoic. There was, in fact, a more general flourishing of life at that point, especially terrestrial. So if you're right we've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition ("Grande Coupure" = The Great Rupture). This seems to have been connected with cooling (rapid Antarctic glaciation), not warming. Oh dear. Apart from the migration of ecosystems polewards and the foraminifera I mentioned I am unaware of a mass extinction event at the petm that you referred to. I would appreciate some referenced material to confirm your point. Otherwise I think we should assume it did not occur.

  633. This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures, when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  634. Weather is not climate. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades.

  635. @jaspercaelan4998  Indeed, but trebling the amount of CO2 in the atmosphere will increase wheat and rice yield by about 35%. So CO2 would not be poisonous at those high levels. Even if CO2 is elevated to 50 times its current concentration, it would not be poisonous and vegetative growth would continue to increase (although seed yield would return to current levels). So still not poisonous.

  640. @Espen_Bos  The fact that such a small number of British could sit atop a system that governed such a huge mass of humanity is a credit to British history. It is a demonstration of the energy and dynamism of the British nation at that time, and totally in keeping with the ways in which pre-industrial societies were organised. Of course it was a pyramid, but it was one overlaid on an Indian society in which it had always been thought proper that a member of higher caste could exploit, abuse and even murder the members of a lower caste as the whim took them. Before the British, the Zamindars were warlords who would rapaciously exploit their own holdings whilst raiding and degrading the lands of other Zamindars. The British pacified them, and brought the rule of law. Besides which all this was just an evolution of the jagirdar system used by the Mughals and the Sultanate of Delhi before that. These agrarian parasites were already there. But they were Indian, not British. This Indian elite creamed off 15% of the national income under the Mughals, and after the latter's collapse, between 1750 and 1810, the despotic indigenous elite extracted upto 50% of production so they could indulge in warfare. Despicable. The British stopped all that, and at the height of the Raj, the Zamindars only took 3% for themselves. The idea that the British somehow drained the life out of India is without statistical foundation. The colonial government was a very small part of economy, and any monies sent out of the country were easily offset by India's trade surplus. India had attracted £380 million in British capital by 1913, £23 billion in today’s money. But Home charges in 1913, the so-called drain from India to Britain, were only £ 11 million, tiny by comparison.

  642. Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr; Newlyn, UK 1.94mm/yr. Jevrejeva, et al (2014) estimated 2 mm/year (± 0.3), and Church and White (2006) estimated 1.7mm/year (± 0.3). So that's a total rise of between 126 and 151mm (less than 6 inches) from 2024 to the end of the century. Or try PSMSL data: Kwajalein (Marshall Islands) 1.95mm/yr; Maldives (Indian Ocean) 3.21mm/yr; Lautoka (Fiji Islands, Pacific Ocean) 3.50mm/yr; Port Elisabeth (South Africa) 2.34mm/yr. Remember, all linear over many decades, or more than a century. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked for each set of satellite data (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a rise of 3.3mm per year. That's the same as two stacked penny coins. There is no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  644. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  645. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  647. Since 1900 the global temperature has increased by 1.3°C. Despite that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than that would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  648. BBC propaganda. Think about it: So people moved from Somalia (where it is dry) to the Gulf States (where it is drier!). This has nothing to do with the climate and everything to do with poverty and bad governance. The reason the Gulf States are a better place to live is they have fossil fuels. Fossil fuel = wealth. What Somalia needs is more fossil fuels to run vehicles, drive machinery and generate electricity. This news item is full of lies.

  650. Propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than that would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  652. Individual dry spells localised to an area are weather events not climate. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  664. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+5°C), another El Niño year, and the trend is now downwards (-0.33°C per decade). HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from this period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  665. Looking at Hansen's predictions (used by the IPCC) running out to 2020. They said that increased human sources of carbon were going into the atmosphere would result higher temperatures. More CO2, warmer world. Scenario A ('Business as Usual') was predicting a little over 35GtCO2/yr by 2020 (21.25 GtCO2 in 1987 with 1.5% predicted annual growth) which exactlty what we got). That should have given a warming in excess of 1.3°C between 1988 and 2000. But it didn't, so did Scenario B, hit the mark? No. Scenario B had emissions of about 21 GtC/yr in 2020. Around 60% of actual emissions, with a temperature rise of around 0.8°C. Oops that prediction was still too hot. Temperature-wise we have to get to Scenario C before we get close to reality. Scenario C predicted a temperature rise of 0.3°C to 2020, but that's with us reaching net zero from 2000! The actual temperature rise was 0.4°C. So Hansen's (and hence the IPCC's) prediction of a huge rise in emissions (which did happen) would result in steep rise in temperature (which didn't happen) is bunk. Instead we got a small rise in temperature, much lower than predicted by Scenario A, and half that of Scenario B. The actual rise was essentially the same as predicted if we had stopped burning fossil fuel. To hammer the point home, Hansen’s predictions were worse than 'Big Oil'. A report from Harvard University noted "projections modeled by ExxonMobil scientists had an average ‘skill score’ of 72 ± 6 %, with the highest scoring 99%. For comparison, NASA scientist Dr. James Hansen’s global warming predictions presented to the U.S. Congress in 1988 had skill scores ranging from 38% to 66%. (When we account for differences between forecast and observed atmospheric CO2 levels, the ‘skill score’ of projections modeled by ExxonMobil scientists was 75 ± 5%, with seven projections scoring 85% or above. Again, for comparison, Hansen’s 1988 projections had corresponding skill scores of 28 to 81%.)" However even the Big Oil overestimated the warming at 0.2°C per decade. The IPCC followed Hansen on other aspects of climate. Both published charts showing the Medieval Warm Period was considerably warmer than the present (Hansen 1984, IPCC 1990). Of course, the Medieval Warm Period has magically ceased to be. Were they right? Are they wrong? Hansen also made some other cracking predictions. In his stagecrafted presentation to Congress in 1998 the New York Times reported his predictions thus “If the current pace of the buildup of these gases continues, the effect is likely to be a warming of 3 to 9 degrees Fahrenheit from the year 2025 to 2050,” and “The rise in global temperature is predicted to… melt glaciers and polar ice, thus causing sea levels to rise by one to four feet by the middle of the next century”. Yes, of course it will, Mr Hansen. In 2006 "We have at most ten years—not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions." So presumably we are FUBARed. In 2009 he said Obama only had four years to save the Earth. Also in 2009 he endorsed a book that suggested razing civilisation to the ground.

  666. As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’

There is no objective observational evidence that we are living through a global climate crisis. None.

  668. Blame climate change does not make any sense. The climate has always changed. This video is drivel. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  669. The retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  670. @christophorfaust2457  If those little girls and their families get richer, and that is what is going to happen, they won't have to haul water. They will, of course, just turn on a tap. And they won't have to chop down trees for firewood, they will just switch on the heating. If they are farmers, modern agricultural methods will allow them to produce more food from less land. They will have less of an impact on the environment, not more. Richer societies divert more resources to the preservation of the environment. It is poverty that degrades the local environment. The little girls who now don't have to haul water, will go to school, and when they come home, they will be able to do their homework thanks to electric lighting. Their higher levels of education will lead to reduced inequality and a lowered birth rate. What's your alternative? Vegan Marxism? 'Big Mother is watching you.' That will not solve your socioeconomic inequality. That communist experiment has been tried repeatedly and caused disaster and misery every time. Unfortunately, there will always be inequality. It is an unpleasant fact of human nature, and you cannot change human nature. Nevertheless people will lift themselves out of poverty if given the right circumstances, and that is what is happening all over the world with the spread of low cost, plentiful energy, and cheap technology. Your point about extinction is also a red herring. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). You say you like data. I hope you like that data.

No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). You say you like data. I hope you like that data.

  672. @christophorfaust2457  Your point about extinction is also a red herring. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011).

  676. This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  685. Weather events are not climate. The severity of individual weather events cannot be attributed to factors implicated in man-made climate change. One cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  687. No. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  688. Quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" s11.5.4, p1569. So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" s11.6.4.5, p1579. So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" s11.7.1.2, p1585. So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" s11.7.2.1, p1592 So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" s11.7.3.2, p1595. "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" s11.7.4, p1598. That's between 60°N and 60°S, so pretty much where everyone lives.

  691. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points - barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  693. Warming events in the Cenozoic do not correlate to mass extinction, whether the warming is correlated to CO2 or not. The Paleocene-Eocene Thermal Maximum PETM (55mya), a time when the Earth warmed rapidly to temperatures far in excess of today's, only resulted in a noticeable extinction of some benthic foraminifera. That was so small of an event it doesn't even show up on a marine extinction intensity chart for the Phanerozoic. There was, in fact, a more general flourishing of life at that point, especially terrestrial. Many major mammal groups appeared and spread around the globe including hyaenodontids, artiodactyls, perissodactyls, and primates. So if the Earth is warming, we've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition ("Grande Coupure" = The Great Rupture). This seems to have been connected with cooling (rapid Antarctic glaciation), not warming. If i can quote from a paper by Aze (2022) "the PETM is not classified as a mass extinction event, as significant levels of extinction are limited to just a handful of taxonomic groups, and overall extinction rates do not increase beyond background levels".

  694. Since 1900 the global temperature has increased by 1.3°C. In that time humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal.

  695. @MariaMartinez-researcher  The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  696. @MariaMartinez-researcher  2022 Pakistan Floods: area flooded 8%, much of this short term. 2010 floods were worse. Both associated with La Niña phase during a Northern Hemisphere summer - a natural phenomenon. There is no connection to the concentration of carbon dioxide in the atmosphere. August 1961 was wetter. For Pakistan's annual rainfall totals the 7-year moving average has barely changed since the 1980s, fluctuating up and down, but with no long term trend. Pakistan has endured major floods long before any significant rise in CO2. Since 1850 Pakistan has experienced 7 major droughts and 6 major floods. Since 1880 there is no trend in excess rainfall or drought conditions over the greater Indian region. I might add the people of Pakistan are also suffering from poverty, bad governance and uncontrolled population growth. In addition in the immediate future they will suffer from the perverse environmental policies of Developed countries that have decided to stop extracting their own energy resources, but will consume the rest of the world's, outbidding poorer countries, like Pakistan, consigning them to darkness and further poverty.

  697. @MariaMartinez-researcher  As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’
    2
  698. @MariaMartinez-researcher  Presumably the major rivers in Europe would need drought to dry up. For studies of drought patterns in Europe: Vincente-Serrano et al. 2020 “Our study stresses that from the long-term (1851–2018) perspective there are no generally consistent trends in droughts across Western Europe.” Oikonomou et al. 2020 “One of the central outcomes of this research is that there is little change in drought characteristics for 1969–2018. It also seems, no particular tendencies for more or less frequent droughts in the two major geographical domains of Europe are present.” IPCC AR6: “in areas of Western and Central Europe and Northern Europe, there is no evidence of changes in the severity of hydrological droughts since 1950” so all the way from the western tip of France to Moscow.

  702. No. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017.

  703. The Arctic minimum summer sea ice trend is zero for the past 18 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 2024 4.28 Plot the trend line for this data and it will be flat. ZERO net change in 18 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). They also noted "the Arctic temperature was higher in the 1930s–40s than in recent decades, and hence a trend calculated for the period 1920 to the present actually shows cooling." Zhang (2021) showed there was no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Including more recent satellite data from Cryosat-2 (2010-2023)reveals the Arctic ice volume minimum (Oct-Nov) is increasing at 56km³/yr (Kacimi and Kwok, 2024). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), an El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  704. If you took away El Niño and Tonga (both natural events) there would be nothing to see. Sea surface temperatures were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two.

  705. Methane (CH4) is only 0.00019% (1.9 parts per million) of the atmosphere. Both of its narrow absorption bands occur at wavelengths where water vapour (H2O) is already absorbing substantially. Hence, any radiation that CH4 might absorb has already been absorbed by H2O. With the concentration of water vapour in the atmosphere being between 1,000 and 20,000 times greater than CH4, the effects of CH4 are completely masked by H2O.

  706. There is no climate crisis. Notice the report says not seen for 2000 years. So it was warmer in the past. It also warmed more rapidly in the past. They often find tree trunks and the remains of forests when the glaciers retreat. It was warmer in the past probably because the Flintstones were burning around in their SUVs.

  707. Since 1900 the global temperature has increased by 1.3°C. Despite that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than the would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only [😉] be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  708. I can find no global observational data on changes to permafrost. The Li et al 2022 paper 'Changes in permafrost extent and active layer thickness in the Northern Hemisphere from 1969 to 2018' states "The temporal change characteristics of the permafrost extent and ALT [active layer thickness] for the NH [Northern Hemisphere] have not been studied." These things have only been poorly estimated or modelled. The aforementioned paper modelled permafrost extent decreased from 23.25 × 10⁶km2 (average from 1969 to 1973) to 21.64 × 10⁶km2 (average from 2014 to 2018), with a linear rate of −0.023 × 10⁶ km2/a. That's an annual change of 0.099 of a percent. That's negligible and could just as easily be increasing due to the uncertainty in the modelling.
    2
  709. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones.

  710. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. It will mean increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming huge amounts of copper and other rare metals for the next 25 years. 1.5 billion tonnes of concrete 42 million tonnes of steel (which is going to need 27 million tonnes of coking coal) 1.9 million tonnes of copper 1.3 million tonnes of zinc 184,000 tonnes of manganese 122,000 tonnes of chromium 56,000 tonnes of nickel 54,000 tonnes of other critical minerals. No doubt all of these materials will be ethically sourced using low carbon processes. Nuclear power would require less than ½ of these resources and Coal power around ¹/10th. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  711. @Lev1232  Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million, the lowest since 1998 (NIFC), and 3% of the burn in the 1900s. It's not hard to understand.

  712.  @Lev1232  Even the extremely biased UN's IPCC AR6 report WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms evidence is lacking or the signal is not present for Fire Weather (hot and windy), leading to overall low confidence of an emerging signal both for the recent past or by 2050 even under the most extreme climate modelling (RCP 8.5). Duhh.

  713.  @JSM-bb80u  But it's a lot lower than the 1930s. That's why they hide that part of the data.

  714. @JSM-bb80u  The data doesn't agree with you. Annual share of the total land area burnt by wildfires in the US went from 0.6% (2012) to 0.4% (2024)(GWIS/FAO UN). There's basically no increasing trend in the data. The areas burnt are comparatively tiny. It's just on the news because it's affecting lots of poorly sited homes in LA.

  715. @JSM-bb80u  I refer you to the data I have already quoted. All the recent values are dramatically lower than those of the 1930s.

  716. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve).

  717. They are not being taken seriously because there is no climate crisis.

  718. Antarctic ice sheet mass loss is about 90 Gt/yr (Otosaka et al, 2023). It's total mass is 24 million Gt, so it loses less than 0.0004% of its mass annually. It contributes 0.36mm to sea-level rise per year (that's pitiful). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. The ice is here to stay.

  719. @CaptHiltz  The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. That's brrrrr-illant 🥶! Get it! So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.

  720. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs.

In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data).

  721. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in Absorbed Solar Radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with Total Solar Irradiance (how shiny the Sun is), which reached an all time record-breaking high in 2023 and 2024 as confirmed by satellite measurement (SORCE and TSIS). 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024)

  722. @old-pete  Does Science explain the lack of evidence or the fact there is no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Mean precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones?
    2
  723.  @old-pete  The table I refer to in the report confirms there is a lack of evidence or no signal that those factors I listed have changed. How about some quotes from the UN's IPCC AR6 WG1 to help you out: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" s11.5.4, p1569. So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" s11.6.4.5, p1579. So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" s11.7.1.2, p1585. So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" s11.7.2.1, p1592 So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" s11.7.3.2, p1595. "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" s11.7.4, p1598. That's between 60°N and 60°S, so pretty much where everyone lives.

  724. @gavinmoody5678  Record heat: If you took away El Niño, a record increase in Total Solar Irradiance, and the Tonga eruption (all natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Total solar irradiance: satellite data from 1979 onwards shows June 2023 at an all time high in over 40 years of measurements (ncei.noaa). There were lows below 1361 W/m² in 2019 to current highs over 1362 W/m² in June (using a lowess curve, which also shows the fastest rate of increase during this recent period). So we are looking at a change of around 1½ Watts over the course of 5 years (the maximum difference is 2.1W/m²). That may not sound much but it exceeds the increase in the Earth's Energy Imbalance (0.9 W/m², 2018 - 1.97 W/m², 2023) (NASA CERES EBAF TOA). Overall the current increase in solar irradiance should give a direct global heating effect of +0.1°C, with an indirect effect of +0.2°C (after Schmutz, 2021). This increase in solar irradiance is related to an earlier than expected increase in sunspot activity, which has not yet reached its zenith, and that may not happen for several years (Royal Observatory Belgium), so further heating from this cause can be expected. So increase in TSI 2019- 2023 = 2.1W/m2. Increase in EEI for the same period ≈ 1W/m². Maybe I'm being dense, but doesn't that mean that without the increase in TSI, the EEI would be in negative territory? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. There is no upward trend in temperature anomalies for summer 2023 according to NOAA USCRN including July. In fact there is no upward trend in the data at all (2005-present). Global Temperature anomaly for July, 2023 = +0.64°C. Global Temperature anomaly for April 1998 +0.62°C Global Temperature anomaly for February 2016 = +0.70°C. (UAH v6) Record disaster: There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). Glacier melt: data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades in the Arctic, and May 2023 was the coldest on record there. The Greenland surface mass balance (SMB) increase for the year 2022-23 was a massive - and well above 1981-2010 average - 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). Greenland has been cooling since 2012. Smog: caused by particulates, not the concentration of CO2. The effects, as you identified are local not global. THERE IS NO EVIDENCE THAT WE ARE LIVING IN A GLOBAL CLIMATE CRISIS.

  725. The mirage of a climate crisis has hardened into a delusion. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  728. @RP S  Presumably, therefore, the point they are trying to make about snow is irrelevant, or at least not proven. And so what if the CO2 is increasing in the atmosphere? Doubling CO2 is going increase the Earth's energy 'budget' by 3W/m² that's less that 1%. That's smaller than the error bar for natural variability. I'm being generous in saying there's a median value for subsequent warming of 1.6K with an upper bound of 2.3K. The variation of the Earth's temperature between one year and the next can be greater than this. The Current Warm Period is minor in its extend and it was warmer in the recent and distant past. It also warmed faster in the past.

  729. @RP S  I wasn't bringing up irrelevant regional temperature changes from the Medieval Warm Period. The Medieval Warm Period was global in extent as demonstrated by research done on every continent and was focused around 1000AD. This extensive research taken together shows that the Medieval Warm Period was both qualitatively and quantitatively warmer than the present. As regards the rate of temperature change for the current modern era, it has been neither consistent nor rapid both temporally and spatially. The climate of the US in the 20th century is good example of this. The US has by far the best actual temperature recordings for this period with very little coverage elsewhere outside of Europe. Data from NOAA (2021) shows uneven warming focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day. All of this demonstrates to my mind that the climate has a strong internal variability without the requirement for any external anthropogenic forcing. Globally satellite data shows how variable the Earth's climate is with changes up or down of more than 1°C occurring from one year to the next. When it comes to comparing the rates of change, as I pointed out previously, the CET and Dansgaard–Oeschger events show much more rapid changes than current observations. When it comes to the extent of the previous warming events, they were not local in nature. The Minoan Warm Period was identified in the Greenland Ice record as well as the Mediterranean. The Roman Warm Period was not just in Rome (see Wang et, 2012, published in Quaternary International) but has also been identified on the other side of the world. Around 1700AD the Little Ice which again was a global event reached its nadir with temperatures possibly 2°C lower than present. Warming proceeded hesitantly from that point (so before the onset of the Industrial Revolution and all the nasty CO2). With initial rapid warming then a cooling in the earlier 1800s, followed by rapid warming again in the early part of the 20th century where the average daily maxima records were set (1930s) and remain extant to this day. There followed a general cooling in the mid-century which lasted until that latter 1970s. Since that point there has been a hesitant warming of 0.13°C per decade. My précis of the Current Warm Period is a little simplistic for brevity but it has been neither consistent nor rapid both temporally and spatially. Projecting forward shows a global temperature increase of 1°C by 2100. This is survivable. Indeed the rise in temperature will encourage the flourishing of humanity and life in general as in previous periods of warming.

  730. @WeToddEd-r3g  No. I faithfully represented the information based on current observations. I included a clear reference so anyone can look it up, and I hope they do. What is remarkable is how little evidence there is that the Global climate has changed or is changing. Some patchy warming based on dubious evidence and that's about it. No changes to droughts, floods or storms. None of that has happened or is happening. I didn't include the information on what was emerging because it is based on implausibly extreme RCP8.5/SSP5-8.5. Those climate scenarios are obsolete, and there use would be misleading.

  731. Channel 4 propaganda. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.

  732. Channel 4 propaganda. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see. There is no climate crisis.

  733. @babuvangu7220  Your time period from 2003 to the present is too short to make reference to climate change, man-made or natural. The minimum period is generally considered to be at least 30 years. Your period also excludes the late eighties and early nineties, a ten year period that was far drier than recently, and the driest period since 1950 with repeated annual rainfall anomalies of minus 200mm or more.

  734. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  735. @lepidoptera9337  It's the "recorded" word that's most important there. Although Phoenix was incorporated in 1881, NOAA only has continuous data from around 1940. So recorded history for Phoenix in this instance is about 80 years (not that long climatically) and the record for 1930s (when heatwaves were worse) is mostly incomplete. Also Phoenix's population has expanded exponentially in that time from a few tens of thousands to a few million. This has dramatically increased the Urban Heat Island effect resulting in temperatures 10°F (5°C) higher during the day (Scientific American, 2019). This alone explains the record high temperatures. As I'm sure you're aware, Phoenix is in the Sonoran desert, which is characterised by long summers and extremely high temperatures. And that's exactly what's happening. There's nothing unusual or unexpected here. The news story is purposely catatrophising the weather to unnecessarily scare people into changing their way of life. There is no global climate crisis.

  736. There is no climate crisis. The Earth was warmer in the recent and distant past. It has warmed faster in the past. This is no climate change. This is poverty. These people need energy resources and good governance. A few coal fired power stations would be a start.

  737. The emperors have no clothes. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015.

  738. Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr; Newlyn, UK 1.94mm/yr. Jevrejeva, et al (2014) estimated 2 mm/year (± 0.3), and Church and White (2006) estimated 1.7mm/year (± 0.3). So that's a total rise of between 126 and 151mm (less than 6 inches) from 2024 to the end of the century. Or try PSMSL data: Kwajalein (Marshall Islands) 1.95mm/yr; Maldives (Indian Ocean) 3.21mm/yr; Lautoka (Fiji Islands, Pacific Ocean) 3.50mm/yr; Port Elisabeth (South Africa) 2.34mm/yr. Remember, all linear over many decades, or more than a century. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked for each set of satellite data (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a rise of 3.3mm per year. That's the same as two stacked penny coins. There is no relationship to the increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  739. @G  I hope you're being hyperbolic when you say "every scientist" and I'm sure you understand that science does not move forward by consensus - that's politics. But just in case...It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020, 2°C above present), and Minoan Warm Periods (Lécuyer, 2018, 4°C above present). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer), far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable. Maybe it was those pesky Neanderthals driving around in their SUVs. That one's been all over the news but if you want a citation I think it was in the 7th December 2022 issue of Nature. The original research was done by some Danish chappy. If you want some really rapid warming look at the CET (Central England Temperature) Record between 1690 and 1730. That won't be reliable enough for you though. Why not try the Dansgaard–Oeschger events? Some researchers believe the Medieval Warm Period was one of these, but I'm not convinced.

  740. Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US so far in 2023 including Maui is 3rd lowest on record. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  741. It's not getting stormier. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, and that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021).

  742. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  744. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature.

  745.  @User_1dashzero  A 1°C warming of the Earth has not proved to be a bad event. It has happened innumerable times in the past as has cooling. Plants can respond to changes to CO2 levels by changing the density of stomata on their leaves. This has been known about for a long time. Lake Mead is a local event not global.

  747. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe. Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice - that can be used as a resting/hunting platform for seals and polar bears - hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. "Greenland ice sheet mass balance from 1840 through next week." (Mankoff et al., 2021). If you examine Fig.2 on page 5, you will see there would be no correlation with the exponential increase in the concentration of carbon dioxide (280ppm to 420ppm) and the change in the annual Mass Balance Sum shown in the paper. Indeed there have been periods of increasing mass of the Greenland ice cap in the 1940's, 70's, 80's and 90's. (Remember CO2 was rising all the time.) More recently Greenland Total Ice Mass Balance rate of loss reached its maximum in 2012 but the trend rate of loss has been diminishing ever since. That's while we've added 500 million tonnes of CO2 to the atmosphere (14% of total human emissions). The average annual loss is 0.005% of the total mass. That's neglible. Come back in 20,000 years. There's no "death spiral" in the region as some people have reported. In fact, there is, I think, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  748. Dogsh1t. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.

  749. Quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" s11.5.4, p1569. So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" s11.6.4.5, p1579. So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" s11.7.1.2, p1585. So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" s11.7.2.1, p1592 So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" s11.7.3.2, p1595. "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" s11.7.4, p1598. That's between 60°N and 60°S, so pretty much where everyone lives.

  750. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no genera have become extinct in the last 500 years. Global temperatures maxed out in 2016 and have been lower ever since (UAH v6 global satellite data). 500 billion tonnes of emissions in that time, and no warming. There is no climate crisis.

Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity.

  755. Since 1900 the global temperature has increased by 1.3°C. Despite that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than that would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  763. If the heat energy content of the World's oceans has increased by 400ZJ since 1960, and the atmosphere has absorbed about ¹/100 th that amount, there is no way an increase of 100ppm of CO2 into the atmosphere has forced that much heat into the ocean. The atmosphere does not hold enough energy. It is not possible for the energy in the atmosphere to affect the ocean temperature changes seen recently or in the long term. In fact the atmosphere is not trapping more energy as the "greenhouse gas" CO2 increases, but the atmosphere is emitting increasing amounts of energy into space as longwave radiation. This is contrary to the idea of man-made global warming. Nearly all of the energy the ocean receives comes directly from sunlight. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in absorbed solar radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with total solar irradiance, which reached an all time record-breaking high in 2023 as confirmed by satellite measurement. 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024)

  766. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021). What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death.

Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020).

That’s an excess death ratio of about 85 to 1 for cold vs. hot temperatures. Due to warmer urban temperatures, the number of premature cold-related excess deaths avoided averaged 447 per year from 1976-2019 in the city of London alone (Hajat et, 2024).

  772. @karlwheatley1244  When it comes to fires, Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? And the fires of 2023 seem to have been largely started by arsonists. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million, the lowest since 1998 (NIFC), and 3% of the burn in the 1900s Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth.

  779. The famine in the Horn of Africa is endemic not because of climatic factors but because of bad governance and poverty. If you compare these regions to the Gulf States, the climate of the Gulf is similar, although even drier, but the latter have a much higher standard of living due their wealth of fossil fuels and better social organisation. What the Horn of Africa needs is a good dose of reliable energy from fossil fuels to raise their living standards.

On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  782. "Heat-attributable mortality fractions have declined over time in most countries owing to general improvements in health care systems, increasing prevalence of residential air conditioning, and behavioural changes. These factors, which determine the susceptibility of the population to heat, have predominated over the influence of temperature change." IPCC "As regards disease, the Lancet's Countdown on Health and Climate Change (2019) shows Climate-related deaths are a small proportion of all-cause fatalities (1990–2017). That is based on data per IHME (2019), and between 1990 and 2017, the cumulative age-standardized death rate (ASDRs) from climate-sensitive diseases and events (CSDEs) dropped from 8.1% of the all-cause ASDR to 5.5%, while the age-standardized burden of disease, measured by disability-adjusted life years lost (DALYs) declined from 12.0% to 8.0% of all-cause age-standardized DALYs. Thus, the burdens of death and disease from CSDEs are small, and getting smaller. However, the declines in death and disease rates from CSDEs since 1990 are only a small proportion of longer-term declines across the globe. In the USA, one of the few places with good long-term data, death rates from dysentery, typhoid, paratyphoid, other gastrointestinal diseases, and malaria – all water-related diseases and therefore, almost by definition, climate-sensitive declined 99–100% between 1900 and 1970. We are solving our problems with CSDEs faster than we are solving our other health problems." Indur M. Goklany If you're worried about deaths due to climate, cold temperature events are the big killer, not heat. It is estimated that 5.1 million people annually die in association with non-optimal temperatures. 4.6 million are linked to the cold, so over 90% (Zhao et al, 2021). And it is worst in the warmer parts of the world. 98% of temperature related deaths in SubSaharan Africa are due to the cold. Temperature events may be linked to upto 10% of human deaths annually. In a warming world there will be less death. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Lives will be saved. Warming is good not bad. A 2022 Lancet study reported 791 heat-related excess deaths and 60,753 cold-related excess deaths in England and Wales each year during the years spanning 2000-2019. That’s an excess death ratio of about 85 to 1 for cold vs. hot temperatures. Due to warmer urban temperatures, the number of premature cold-related excess deaths avoided averaged 447 per year from 1976-2019 in the city of London alone (Hajat et, 2024).

  783. @jackwang9536  I do choose my data wisely, and from reputable sources. I also include the numbers or ratios of heat to cold deaths and all the sources for my data, which you do not. For example Europe as whole had overall ratio of 10.09 cold-related deaths for every heat-related death (Boretti, 2024), so you can take whatever value you give for heat-related death and add a nought to it for cold-related deaths. Choosing my data wisely, another Lancet study (Liu et al, 2019) on temperature related death in China showed for every heat related death there were 42 cold-related deaths for every heat-related death. Or 580,800 deaths due to cold and only 13,900 due to heat in the whole of China.

  784. Who cares? There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  785. I get emotional when I think about all the unnecessary poverty future generations may have to endure because a bunch of carbon-cult nutters decided to spaff all our wealth and energy up the wall just to virtue signal about a non-problem. The rest of the world are going to sail past the West laughing as we regress back to the Dark Ages on what is, in reality, a warmer, greener planet.

  786. When it comes to fires, Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million and the lowest since 1998 (NIFC). Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there was nothing unusual about 2023 summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  788.  @acajoom  Your ad hominem remarks regarding my character are merely a diversion. It doesn't matter what I am. You are attempting to divert yourself and others from the facts, the objective reality, probably because it does not sit well with your internal narrative regarding the world. You cannot argue against the facts so you insult me in the hope of downgrading the worth of those facts in order that you do not have to accept the truth, and damage your own internal narrative as that would be too uncomfortable for you.

  793. The indigenous people did not have science. Making mud into a small town, although impressive for a Stone Age society, is not Science. They threw up these mounds to glorify their non-existent gods and spirits, or to identify as powerful the priests and witch-doctors who imagined these false deities into being. They didn't have Scientific methodology which must include the following: *Objective observation: Measurement and data collection and manipulation *Evidence *Experiment and/or observation as benchmarks for testing falsifiable hypotheses *Induction: reasoning to establish general rules or conclusions drawn from facts or examples *Repetition to establish repeatability *Critical analysis *Verification and testing: critical exposure to scrutiny, peer review and assessment. The lives of the people of Cahokia would have been circumscribed with superstition and pointless ritual, not an objective knowledge of reality. And knowledge is not Science. Science is a process. It is how we test and falsify ideas using mathematics. Knowledge is not Science. Science is not knowledge. The broadening of definition to dilute the meaning of the word "science" to suit one's needs will not do. What the people of Cahokia achieved, although to be enjoyed and marvelled at, did not require science, but was a product of simple trial and error - which is not the same as evidence and experimentation - often with pointless goals, for example the glorification of supernuminous beings. Prior to the Enlightenment numerous civilisations produced many great and beautiful creations, often in excess of that produced by those who inhabited Cahokia and its environs, but without the possibility of any recourse to scientific methodology. This is not to decry what was constructed there. Cahokia is a wonder not because the people their 'had science' but because they did not. I don't "want" the Mississippian Culture to be inferior to modern Western Culture, it just patently is on so many levels. Codification of Law. People are considered equal before the Law in Western societies. Representative Democracy. One man, one vote with the ability to remove representatives and limit their terms of office. Equality of the Sexes. All previous societies were overtly misogynistic. The freedom of conscience. I don't have to believe in anything if I don't want to. The abolition of slavery. Until the advent of modern Western thought slavery was considered to be normal in all societies. The continuing application of advances made by Science in all areas of technology. For example, the use of Physics and Chemistry in the supply of essentially limitless supplies of energy that frees humans from drudgery and back-breaking labour. The use of Science in the development of modern medicine. Understanding disease, the development of antibiotics and innumerable other treatments and advances in sanitation. The application of Biology to plant and animal husbandry so that for the first time in history you are more likely to be over-fed than under-fed. The list goes on. You obviously don't know how lucky you are. This is the best time to be alive. If you were born in Cahokia around the 12th Century in all likelihood you would be dead of some nasty little disease by the age of 5. If you survived and weren't from a powerful family (so at least 95% of the population) you could look forward to a life of unremitting toil growing and preparing corn. As a woman, you would have had no self-control over the direction of your life. Decisions about you would have been taken by your father, husband or some self-glorified noble or priest. If not an actual slave, you could expect to be treated little better than one. You would have had no recourse to the Law. There was no Law, only the arbitrary exercise of power by a ruthless all male elite. If you made it to puberty the risk existed that you would be made a human sacrifice, probably by strangulation, and put in a mass grave, so that you could serve and gratify some dead chief in his non-existent afterlife. If you did make it to adulthood you would be constantly pregnant and most likely die in childbirth. By 30 you would old and exhausted. A likely cause of death would be a minor infection often from tooth decay.

  794. The Arctic minimum summer sea ice trend is zero for the past 18 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 2024 4.28 Plot the trend line for this data and it will be flat. ZERO net change in 18 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). They also noted "the Arctic temperature was higher in the 1930s–40s than in recent decades, and hence a trend calculated for the period 1920 to the present actually shows cooling." Zhang (2021) showed there was no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Including more recent satellite data from Cryosat-2 (2010-2023)reveals the Arctic ice volume minimum (Oct-Nov) is increasing at 56km³/yr (Kacimi and Kwok, 2024). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  797. In the past few months, the World's Sea Surface Temperature (SST) has declined by 0.5°C so that it has returned to the temperature in December 2015 (Daily Sea Surface Temperature World 60°N-60°S 0-360°E NOAA OISST V2.1 dataset available on the ClimateReanalyzer website). The recent off trend temperature rise began before El Niño and was not predicted by climate scientists. The size of the temperature rise was not predicted by climate scientists. The rapid cooling of the ocean back down 2015 levels before the commencement of the next La Niña was not predicted. If the heat energy content of the World's oceans has increased by 400ZJ since 1960, and the atmosphere has absorbed about ¹/100 th that amount, there is no way an increase of 100ppm of CO2 into the atmosphere has forced that much heat into the ocean. The atmosphere does not hold enough energy. It is not possible for the energy in the atmosphere to affect the ocean temperature changes seen recently or in the long term. In fact the atmosphere is not trapping more energy as the "greenhouse gas" CO2 increases, but the atmosphere is emitting increasing amounts of energy into space as longwave radiation. This is contrary to the idea of man-made global warming. Nearly all of the energy the ocean receives comes directly from sunlight. The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in Absorbed Solar Radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with Total Solar Irradiance (how shiny the Sun is), which reached an all time record-breaking high in 2023 and 2024 as confirmed by satellite measurement (SORCE and TSIS). 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024)

  800. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.

  801. If you took away El Niño and Tonga (both natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP. There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

  802. Takeaway the report and use it as toilet paper. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The Earth has greenedDrought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  803. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  806. This is cherry-picking weather events. That's not climate. This is climate: Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis.

  807. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  808. In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". Antarctic sea ice extent is an unusual weather event dressed up as the end of the world. Antarctic sea ice was at a record maximum in 2015. No one mentioned that as part of a climate crisis. And why don't we hear about the Arctic? Because there's been no warming there this summer. Summer 2023 is one of the coldest in decades in the Arctic, and May 2023 was the coldest on record there. The Greenland ice sheet surface mass balance (SMB) for the past 11 months is a massive 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). Data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic, and September, 2023 was 4.23. Both of these are higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. But you won't be told any of these facts on the news. They don't fit the story. Because that's what it is make-believe.

  809. Weather events are not climate. The severity of individual weather events cannot be attributed to factors implicated in man-made climate change. One cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  811. 8:27 They start the graph at 1983 for a reason. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Notice how they don't include 2023, although that data is available. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million, the lowest since 1998 (NIFC), and 3% of the burn in the 1900s. Annual share of the total land area burnt by wildfires in the US went from 0.6% (2012) to 0.4% (2024)(GWIS/FAO UN). There's basically no increasing trend in the data. The areas burnt are comparatively tiny. This is BBC propaganda.

  813. I'm afraid the Doomsday glacier has lost its doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  815. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  818. This is a scare story about things you cannot see. Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  819. Antarctic ice sheet mass loss is about 90 Gt/yr (Otosaka et al, 2023). It's total mass is 24,380,000 Gt (24380000000000000 tons), so it loses less than 0.0004% of its mass annually. It contributes 0.36mm to sea-level rise per year (that's pitiful). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. The ice is here to stay. There's also a bit of a problem with your "accelerating continental ice loss in Antarctica" position. It's not accelerating. If you want to dig down to the actual data, that is. Just so we're clear, I'm referring to the paper entitled "Mass balance of the Greenland and Antarctic ice sheets from 1992 to 2020" by Otosaka et al, 2023. Can I direct you to table 2, and the text below it? If we include the APIS in "continental" (although I wouldn't) there's no pattern with a slight loss overall - neglible. EAIS, by far the larger of the continent's ice caps, both by surface and volume, hasn't lost mass. It has gained mass, but again it's neglible. So that leaves us with WAIS. It's only WAIS that's driving the mass loss from Antarctica, and you can see that from the Figure 4 graph. Figure 4 and Table 2 show there is a step up in mass loss around 2007. You might want to call that an acceleration. However there's a deceleration from 2017 or at least a noticeable reduction in the rate of annual ice mass loss for the period 2017-2020 when compared to 2012-2016. So accelerating then decelerating. Not really though, is it? These are such miniscule periods of Time.

  821. Another climate propaganda video. If you took away El Niño, a record increase in Total Solar Irradiance, and the Tonga eruption (all natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP.

  823. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+5°C), another El Niño year, and the trend is now downwards (-0.33°C per decade). HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from this period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  824. As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’

  825. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940.

  829. The usual nonsense. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe. Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice that can be used as a resting/hunting platform for seals and polar bears hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. There's no "death spiral" in the region as some people reported. In fact, there is, as I say, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  830. @karlwheatley1244  Warming events in the Cenozoic do not correlate to mass extinction, whether the warming is correlated to CO2 or not. The Paleocene-Eocene Thermal Maximum PETM (55mya), a time when the Earth warmed rapidly to temperatures far in excess of today's, only resulted in a noticeable extinction of some benthic foraminifera. That was so small of an event it doesn't even show up on a marine extinction intensity chart for the Phanerozoic. There was, in fact, a more general flourishing of life at that point, especially terrestrial. Many major mammal groups appeared and spread around the globe including hyaenodontids, artiodactyls, perissodactyls, and primates. So if the Earth is warming, we've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition ("Grande Coupure" = The Great Rupture). This seems to have been connected with cooling (rapid Antarctic glaciation), not warming.

  831. The mass extinction is not already on its way. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years. It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. So to summarise, from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. It does not follow from this that we shouldn't cherish and nurture the life that there is on this planet, but it is important to have a clear perspective on the situation.

  834. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence).

  835. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  836. Quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" That's between 60°N and 60°S, so pretty much where everyone lives.

  840. If you're worried about deaths due to climate, cold temperature events are the big killer, not heat. It is estimated that 5.1 million people annually die in association with non-optimal temperatures. 4.6 million are linked to the cold, so over 90% (Zhao et al, 2021). And it is worst in the warmer parts of the world. 98% of temperature related deaths in SubSaharan Africa are due to the cold. Temperature events may be linked to upto 10% of human deaths annually. In a warming world there will be less death. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Lives will be saved. Warming is good not bad. A 2022 Lancet study reported 791 heat-related excess deaths and 60,753 cold-related excess deaths in England and Wales each year during the years spanning 2000-2019. That’s an excess death ratio of about 85 to 1 for cold vs. hot temperatures. Due to warmer urban temperatures, the number of premature cold-related excess deaths avoided averaged 447 per year from 1976-2019 in the city of London alone (Hajat et, 2024).

  843. @cyberfunk3793  As regards drought etc: The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis.

  845. @cyberfunk3793  I assume you would include California in your definition of southwestern US. As of November (2023) it had received 141% of its historical average annual (water year) precipitation, its reservoirs were at 128% of their historical average, and statewide snowpack was at 237% of its historical average (sourced from California Water Watch). Today I checked the US government's Drought website (with data sources from NOAA, etc) and 0% of California was in drought. Zero. No drought. It's an interesting website and it shows there is no pattern to how wet or dry the state is over short or long timescales. So no evidence of man-made climate change in this area of the globe. And certainly not evidence of a man-made global climate crisis.

  853. Nonsense. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests.

  859. @Ottotherepoman1  I obviously have no idea on the location of your personal glacier. But changes to individual glaciers do not point to a man-made global climate crisis. Let's look at a range of glaciers around the world rather than your unsubstantiated individual report: the retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  860. The CSI is based on the relative frequency of daily temperatures in the current climate and in a world without human-caused climate change. Unfortunately, one cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no extra CO2 had been added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

Of course we've only had about 0.1°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it! But there is still no crisis just an unexciting set of observations. All the climate models run too hot, 100% of them. The attribution of all warming to human activity by the IPCC is junk science as well. Take AR5: that says all observed warming (0.66°C) since 1950 is due solely to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 is particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative.

  863. @brmadden895  The Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.06°C/decade.

  868. @brmadden895  If you're desperate to know my position...It is reasonable from observations to say the Earth is warming. All the models run too hot. It does not appear possible to discern how much of the warming is man-made, so it seems unreasonable to affirm that all of the warming is man-made, but adding CO2 to the atmosphere should cause some rise in temperature. However the warming response should be logarithmic and empirically the ECS is around 1.8K. When you look at actual instrumental records the warming is uneven both spatially and temporally. There is very little warming around the tropics. The Canadian Arctic has warmed. Continental Antarctica (excluding the Peninsula) has cooled significantly (so no "global" warming). Maybe it's a Bond Event. Within the shallow warming there are large annual swings greater than the decadal rate of change. It is also debatable how hot the modern era is in comparison to recent and distant warming events, and when making a fair comparison with proxies by using the same resolution (say 200 year) the rate of warming becomes comparable to, or smaller than previous natural events.

  870. @brmadden895  I might answer those if you can answer these: Why has the north Atlantic warmed rapidly and repeatedly during the current interglacial with no correlation to CO2, e.g., 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP? And why is there a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2?

  873. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  879. Newsflash! This just in! Arctic temperatures peaked over 8 years ago! The Arctic (Land and Ocean) average temperature anomaly peaked at +4.99°C for the month of January 2016. The trend has been downwards ever since. It currently lies at +2.69°C (April 2024). Also April 2024 does not hold the record for the largest Global Land and Ocean monthly temperature anomaly. It comes in at 9th place. This data is from NOAA, and its extensive climate database.

  883. There is no climate crisis. It was warmer in the recent and distant past. It has warmed faster in the past. The current warming started before the use of fossil fuels. The use of fossil fuels has ensured that the majority of humanity no longer subsist in absolute poverty. The additional CO2 is plant food and is greening the planet. These people are deluded.

  885. Here's a conspiracy of truths: There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  886. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23. Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Zhang (2021) shows there is no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  887. @PhilMcr  Only in some very small part. I mainly base it on the fact that I have yet to come across any objective observational evidence that we are in a global climate crisis. The Earth warming by one-tenth of a degree every decade is not a crisis.

  888. ​@Teebs131 As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

  890. Panama canal's problems are due to population not climate. The management of the lakes that supply water to the canal itself also supplies water to the local population. The population has increased by a factor of 5 since 1950, and personal income, and along with it water consumption has ballooned. The water supply comes from the very same lakes that supply the canal.

  893. @edwardbrown8933  The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". A study of Antarctic ice shelves from 1980 to 2021 (Banwell et al, 2023) showed meltwater volume dropped with "decreasing trend in both annual melt days and meltwater production volume over the 41 years.” "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high. Antarctica contributes 0.36mm to sea-level rise per year (that's essentially nothing as well). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. That ice is here to stay.

  901. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  902. When it comes to fires, Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? And the fires of 2023 seem to have been largely started by arsonists. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million, the lowest since 1998 (NIFC), and 3% of the burn in the 1900s Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there was nothing unusual about 2023 summer's fire season in Europe (look it up on the EFFIS website). The burned area was lower than 2021, 2022, and most of the 80's and 90's. In Portugal, Spain, France, Italy and Greece 2023 was only the 20th highest in the modern satellite burnt acreage record going back to 1980. Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  903. @jordaneggerman4734  The AMOC tipping point is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC will collapse by the end of the century. Come on! Really? These numerical models produce ocean circulations that are far from what we actually observe. These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents. The most recent research into the AMOC confirms it is not weakening. From a 2024 paper by Terhaar et al published in Nature Communications "Based on the here identified relationship and observation-based estimates of the past air-sea heatflux in the North Atlantic from reanalysis products, the decadal averaged AMOC at 26.5°N has not weakened from 1963 to 2017". "Based on the results, the AMOC is more stable than we thought," Vogt said (one of the authors on the paper). "This might mean that the AMOC isn't as close to a tipping point as previously suggested." So not even close to a tipping point or collapse. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures -Rahmstorf must be gutted - when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact.

  904. I'm afraid the Doomsday glacier has lost its doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  905. @astro nautical  I think my point is that there is objectively no climate emergency. What may be happening is political group-think on eco-catastrophism is infecting institutions, science and otherwise, that one would hope were immune to their enticements. The power, status and public funds would constitute such enticements. But that's just my supposition. It would be hard to find data either way on such a hypothesis. Unlike climate data.

  906. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades.

  907. @KC  Air conditioning is a luxury that only a very small number of people on this planet have access to or can afford - whatever the weather. Humans evolved in Africa and unlike most other mammals we are covered in sweat glands. So my advice, just like the 1930s, is have a good sweat. Or turn on a fan. Or have a siesta. Or redesign buildings and streets so they cool passively. If you must, put the aircon on. The additional CO2 will have little effect on global warming. Just have a look at a Stefan Boltzmann curve for our atmosphere. ECS about 1.6K.

  908. Lies and propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). There is no climate crisis.

  910. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  913. @Ra Ra  The current warming began around 1700 prior to any large scale combustion of fossil fuels. Also the warming has been small (1°C) and appears to have been largely beneficial. It has not been smooth, for example there was a period of cooling during the 50s, 60s and 70s (NOAA). When many scientists believed the next ice age had begun. Current warming is smaller than predicted by all models (actual is 0.13°C per decade since 1979, UAH v6) so around ½°C for the past 40 years but no overall warming over the past 8. This will result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°.

  914. @RaRa-eu9mw  There is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling with little change in trend around the Equator (NOAA-STARv5 TLT & TMT 1979-2023). Overall the Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade.

  915. It was dogsh1t then and it's dogsh1t now. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  917. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  918. People don't understand net zero and how it's going to ruin them.Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 20 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. Imagine the damage done from all that resource extraction! And for what? Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  920. @pwollerman  Fair enough. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". A study of Antarctic ice shelves from 1980 to 2021 (Banwell et al, 2023) showed meltwater volume dropped with "decreasing trend in both annual melt days and meltwater production volume over the 41 years.” "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high. Antarctica contributes 0.36mm to sea-level rise per year (that's essentially nothing as well). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. That ice is here to stay.

  931. Current warming is smaller than predicted by nearly all models (0.13°C per decade since 1979, UAH v6) so around ½°C for the past 40 years but no overall warming over the past 8. This will result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°. Please be aware that the IPCC's (Scenario A) modelled predictions are junk. Back in 1990 they predicted a warming of 0.30-0.34°C per decade. Of course we've only had 0.13°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it. But there is still no crisis just an unexciting set of observations.

  935. This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures, when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  936. There is no climate crisis. The Earth was warmer in the recent and distant past. It has warmed faster in the past. Burn more fossil fuel to generate wealth to pull people out of poverty and stop asking for other people's money.

  937. 2023 was not the hottest year over large parts of the globe. Asia, Europe, U.S., Oceania, East N. Pacific Region, Hawaiian Region, Arctic, and the ANTARCTIC all enjoyed their highest regional average temperature anomaly in previous years according to data released by NOAA.

  938. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  939. @MilitantPacifist69  I am, of course, fully aware that thermometers, after a fashion, have been in use for centuries. That does not mean, however, that they have been used consistently and repeatedly everywhere for centuries. During the latter half of the nineteenth century reliable records are only really available from parts of Europe, USA and eastern Australia, with a very small number of reliable stations outside of that. Even before 1950 there are essentially no GHCN-Daily stations in South America, India, S. E. Asia, China, Africa, or around the Poles.

  940. Although the Royal Navy is a remarkable institutional, which to its credit stamped out the slave trade. A single British man o'war taking temperature readings as it traverses the ocean isn't going to provide the calibrated long term readings from individual locations. The warming in the current modern era has been neither consistent nor rapid both temporally and spatially. The climate of the US in the 20th century is good example of this. The US has by far the best actual temperature recordings for this period with very little coverage elsewhere outside of Europe as I mentioned previously. Data from NOAA (2021) shows uneven warming focused on the South East through until it peaks in the 1930s. Some areas of the West showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day. All of this demonstrates to my mind that the climate has a strong internal variability without the requirement for any external anthropogenic forcing. Globally satellite data shows how variable the Earth's climate is with changes up or down of more than 1°C occurring from one year to the next.

  943. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

  945. @Richard482  Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr; Newlyn, UK 1.94mm/yr. Jevrejeva, et al (2014) estimated 2 mm/year (± 0.3), and Church and White (2006) estimated 1.7mm/year (± 0.3). So that's a total rise of between 126 and 151mm (less than 6 inches) from 2024 to the end of the century. Or try PSMSL data: Kwajalein (Marshall Islands) 1.95mm/yr; Maldives (Indian Ocean) 3.21mm/yr; Lautoka (Fiji Islands, Pacific Ocean) 3.50mm/yr; Port Elisabeth (South Africa) 2.34mm/yr. Remember, all linear over many decades, or more than a century. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked for each set of satellite data (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a rise of 3.3mm per year. That's the same as two stacked penny coins. There is no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  946. @Richard482  The problem with all these models and projections is that Antarctica is not playing the game. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". A study of Antarctic ice shelves from 1980 to 2021 (Banwell et al, 2023) showed meltwater volume dropped with "decreasing trend in both annual melt days and meltwater production volume over the 41 years.” "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high. The Greenland ice sheet is thought to contribute 0.7mm/yr to sea-level rise. That sounds small because it is pitifully small. Antarctica contributes 0.36mm to sea-level rise per year. (That's essentially nothing as well.) The remainder is due to the thermal expansion of the ocean, and is a signal of past warming rather than current.

  950. @Richard482  That paper states that warming is localised to the South Pole (which remains very sub zero), and that the Antarctic Peninsula is cooling. These conditions are not going to lead to Antarctica making any contribution to a rise in sea level.

  951. There is no schedule. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis.

  954. As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’

  955. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. It's still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe. Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice that can be used as a resting/hunting platform for seals and polar bears hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. There's no "death spiral" in the region as some people reported. In fact, there is, as I say, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  959. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The Earth has greenedDrought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  965. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  967. @utubenico41  Shall we get ourselves informed about scientific facts? There is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling with little change in trend around the Equator (NOAA-STARv5 TLT & TMT 1979-2023). Overall the Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming globally. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade, so when you look at actual instrumental records the warming is uneven both spatially and temporally. It's not simple it's complicated. America has by far the best instrumental data, and it shows overall the South East cooled in the last 120 years. Though that sentence doesn't do justice to the climate's variability. Data from NOAA (2021) shows uneven warming in the twentieth century focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West US showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day. There will be huge parts of the globe where no measurements will have been taken until the advent of satellite technology towards the end of the 70s. During the latter half of the nineteenth century reliable records are only really available from parts of Europe, USA and eastern Australia, with a very small number of reliable stations outside of that. Even before 1950 there are essentially no GHCN-Daily stations in South America, India, S. E. Asia, China, Africa, or around the Poles. With such patchy poor quality data it is impossible to say the Earth has never warned faster. The big problem for you doomists is peak interglacial warmth is not now but around 8,000 years ago. Proxies show a downward trend to the present day but with an interruption for the Medieval Warm Period (that doomists aren't allowed to believe in) followed by a decent into the The Little Ice Age (which doomists think also didn't exist), and a very slight recovery to the present day still below MWP though. Now I know what you're going to say about the supposed rapid warming over the last century but that's not a fair comparison. That's instrumental - which is unreliable -with annual instrumental measurements compared with proxy data whose the resolution is 200 years. If we smooth out the current data over the last two centuries you'd be lucky to see ½ degree per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century). And let's not forget the Dansgaard–Oeschger events. The Dansgaard–Oeschger events were global (Dima et al, 2018). One about 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8°C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. So shall we say a rate of change about 20°C per century. If that happened now you'd be foaming. But life carried on.

  970. When it comes to tipping points this is what the IPCC (Special Report on implications of 1.5C or more warming, Chapter 3) says:“there is little evidence for a tipping point in the transition from perennial to seasonal ice cover. No evidence has been found for irreversibility or tipping points, suggesting that year-round sea ice will return given a suitable climate”. The IPCC also do not believe the melting of the arctic permafrost will cause a tipping point in the release of warming methane gas “the carbon released to the atmosphere from thawing permafrost is projected to be restricted to 0.09–0.19 Gt C yr–1 at 2°C of global warming and to 0.08–0.16 Gt C yr–1 at 1.5°C, which does not indicate a tipping point”. The Earth's climate is a multi input thermodynamic system and will conform to Le Chatelier's Principle.

  974. Propaganda. Greenland Total Ice Mass Balance (1986-2022): declines to 2012 but increases to 2022.It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer), far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable.

  975. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  977. @8fledermaus8  The "weather events" are not "getting more powerful". There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades.

  978. @8fledermaus8  The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2
    1
  979. @8fledermaus8  But El Niño does explain the warming, and it is a natural event. ENSO (El Niño) shows no trend or pattern for this natural occurrence. I refer you to The Royal Netherlands Meteorological Institute (KNMI) Southern Oscillation Index (SOI) – 1882 to Present. Overall the Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade. This gets you less than 1°C warming by 2100. This year's immediate warming isn't even anything special or the hottest. Global Temperature anomaly for August, 2023 = +0.69°C. Global Temperature anomaly for April 1998 +0.62°C Global Temperature anomaly for February 2016 = +0.70°C. (UAH v6)

  986. @Lies Tricks I'm not lying, and in fact, I agree with you. If you take the linear trend in the data it's a touch over a tenth of a degree per decade. As you have in your reply. But also that pace of warming has slowed or paused in the last 8 years. No doubt some warming will continue.But the atmosphere does not appear to be as sensitive to the addition of CO2 that many people and their models expected.

  987. If you took away El Niño and Tonga (both natural events) there would be nothing to see. Sea surface temperatures were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two.

  994. @joanapersoa  The Earth has certainly not lost that percentage of wildlife to extinction. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 908 known lost species for 2.1 million known species in 500 years (IUCN Red List), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). Take bird species: 11,195 have been counted (not estimated). All of these have been assessed by the IUCN. They catalogued 4 bird species became extinct over the course of 28 years between 1988 and 2016. That's 1.4 per decade or an annual extinction rate of 0.001%. Also the proportion of species assessed as threatened by the IUCN has declined rapidly over time, from 65% in 2000 (11,000 out of 17,000) to 28% in 2024 (46,000 out of 166,000). This increasingly positive outcome of their species assessments is only accelerating as time passes. Using IUCN data on assessed species- Amphibian species extinct 0.009% per decade. Mammals 0.029% per decade. Reptiles 0.006% per decade. Fish 0.006% per decade. Insects 0.009% per decade.

  1001. @mitkoogrozev  The silliness is you don't know the difference between a graph and a table. The reason I've specifically referred to that table is it is a summation of the scientific information contained within the report. It demonstrates that even when you have an extremely biased organisation such as the UN, they can find very little evidence of any serious attributable man-made climate change having taken place or taking place (remember any climatic change since 1950 they maintain is due to mankind). Of the thirty-three 'climate impact driver categories' they only have a high confidence that 5 of those categories have changed. For 24 of those categories they can't find a change. That's after at least 70 years of us supposedly being the main drivers of climate change. Of those 5 high confidence categories, 1 is extra CO2, and 2 are basically the same thing - heat. When it comes to the heat, one of the relevant papers referenced by the IPCC in support - Perkins-Kirkpatrick and Lewis, 2020 - has the number and length of heatwaves increasing globally (1951-2017) as you would expect in a slowly warming world, but there is no trend for average intensity. Notice when it is predicted what will emerge in the future they use RCP8.5 - The most extreme of modelling. Truly laughable. And even then very little emerges. Maybe a little more rain in some places, maybe a little less in others. Still no change in droughts. It's not looking good for you alarmist. When you're worried about "the ocean life we've decreased" let's have a look at some actual data rather than your pontification. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022 and 2023 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction.

"The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019).

  1008. @Brandon Liechti  You need to be aware that the problems with plastic have been overstated and the alternatives can be more damaging to the environment. Eriksen et al (2014) discovered 250,000 tons in the ocean. Although that seems a lot, except when you consider the ocean is 135,000,000,000,000,000,000 tons. It was 0.1% of annual plastic production. Plus they found 100 times less microplastic than expected. Several groups of scientists (e.g. Ward et al, 2019) have found some plastics e.g. Styrofoam, readily disintegrate in seawater to organic carbon and CO2. The supposedly environmentally friendly alternatives to plastic are not. Banning plastic bags results in more pollution because of the greater amount of energy needed to produce alternatives. Glass bottles consume upto 250% more energy than plastic ones in production, and paper bags would have to be used 43 times to have a smaller impact on the environment. Highly unlikely.

  1015. ​@pkerber The Arctic summer sea ice trend has been zero for the past 17 years. There is now a 90% probability that climate scientists predictions about the loss of Arctic sea ice are wrong. If the pause in ice loss continues until 2027, it will no longer be explainable by chance (Swart et al, 2015), or indeed human-induced global warming.

  1016. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  1019. @davecooper3238  I can find no global observational data on changes to permafrost. The Li et al 2022 paper 'Changes in permafrost extent and active layer thickness in the Northern Hemisphere from 1969 to 2018' states "The temporal change characteristics of the permafrost extent and ALT [active layer thickness] for the NH [Northern Hemisphere] have not been studied." These things have only been poorly estimated or modelled. The aforementioned paper modelled permafrost extent decreased from 23.25 × 10⁶km2 (average from 1969 to 1973) to 21.64 × 10⁶km2 (average from 2014 to 2018), with a linear rate of −0.023 × 10⁶ km2/a. That's an annual change of 0.099 of a percent. That's negligible and could just as easily be increasing due to the uncertainty in the modelling.

"Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  1031. @Reinhard..  I'm not quite sure what "from until" means, but I am, of course, fully aware that thermometers, after a fashion, have been in use for centuries. That does not mean, however, that they have been used consistently and repeatedly everywhere since 1880. During the latter half of the nineteenth century reliable records are only really available from parts of Europe, USA and eastern Australia, with a very small number of reliable stations outside of that. Even before 1950 there are essentially no GHCN-Daily stations in South America, India, S. E. Asia, China, Africa, or around the Poles.

  1034. This is what really is happening: Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis.

  1036. Since 1900 the global temperature has increased by 1.3°C. In that time humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  1039. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS), and that is despite reports of supposed repeated bleaching, despite starfish predation and despite any bad weather. It should be renamed the Greatest Barrier Reef! If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  1041. @user-jk3ht5hn3m  There's lots of information about the Arctic that doesn't fit the acceptable narrative. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  1042. The mirage of a climate crisis has hardened into a delusion. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1049. @Gary Anthony  What exactly was I wrong about? In 2022, AIMS LTMP (long term monitoring programme) found record high coral cover on the Great Barrier Reef of 0.34 (i.e. 34% of the seabed on the coral reefs monitored are covered with coral). Over the past 36 years, cover has varied dramatically, and reached a low point in 2011 of 0.12. There is about twice as much coral in 2022 as in 2011. Since 2016 there has been a rapid rise in cover, despite four bleaching events occurring between 2016 and 2022. I did not make any predictions, so presumably I can't be wrong about that either. Although how corals are going to become extinct from an average temperature rise of a few tenths of a degree is beyond me, especially when you consider the Indo-Pacific Warm Pool – the hottest major water mass on earth has the most diverse reefs, and its waters are warmer than those of the Great Barrier Reef. Coral are warmth loving animals. As the oceans warm they will be able to spread away from the equator. Their range will expand.
    1
  1050. @Gary Anthony  From that, I take it that you were wrong to say I was wrong. As regards sea surface temperature, it is the only environmental predictor highly related to marine biodiversity. Lower temperatures are related to fewer species. The highest sea surface temperatures are associated with the highest biodiversity. Corals will survive the rise in temperature. They will expand their range as they need warm water to survive. They survived previous warmer periods, e.g. the Medieval Warm Period, the Holocene Climatic Optimum, the Eemian Interglacial, the PETM, etc, etc. They survived hundreds of millions of years of Earth's history when it was considerably warmer than it is now.

  1051. @Gary Anthony  Oh dear. Confronted with evidence, and you deny it. Coral is most diverse in the warmest parts of the world’s oceans. This applies not just to coral but has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. That is a fact.

  1052. @Voidisyinyang Voidisyinyang  I don't know who's expecting cyclones to become more frequent and intense. Using data from the JMA (1951-2022), we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years. As I stated before there is about twice as much coral in 2022 as in 2011. Since 2016 there has been a rapid rise in cover, despite four bleaching events occurring between 2016 and 2022. Climate alarmists don't like this because it refutes all their failed predictions over many many years, so I have no agreement with the latest ones about the wrong type of coral on the brink of being destroyed by imaginary storms. Answer me this: how are corals going to become extinct from an average temperature rise of a few tenths of a degree, especially when you consider the Indo-Pacific Warm Pool – the hottest major water mass on earth has the most diverse reefs, and its waters are warmer than those of the Great Barrier Reef? Are Coral warmth loving animals largely confined to tropical waters? As the oceans warm shouldn't they be able to spread away from the equator, and expand their range?

  1053.  @Muddslinger0415  The current warming we are experiencing is shallow (0.13°C per decade, UAHv6). This is less than all the models. Importantly, it has produced none of dire global consequences predicted. None. Zero. So there is no climate crisis.

  1057. @8fledermaus8  Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  1058. This climate report is propaganda. The CSI (Climate Shift Index) is based on the relative frequency of daily temperatures in the current climate and in a world without human-caused climate change. Unfortunately, one cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no extra CO2 had been added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  1059. The Royal Society recommend the UK should have 100TWh of energy storage by 2050 (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. A typical pumped storage facility has a 300 to 400m dam built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the less than 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the whole Earth going Net Zero. Good luck with that.

  1060. I'm afraid the Doomsday glacier has lost its doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  1061. There is no climate emergency. The Earth was warmer in the recent and distant past. It also warmed faster in the past. In 20 years from now there will be grass growing in my jawbone and still the climate emergency will not have happened.

  1064. @Junieper  As regards the melting of Arctic Ice, the doomsters records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. And now it's gone down again. So what? Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe.

  1066. @Junieper  Are you choosing to ignore data from before 1979? How convenient, as it shows growth in the ice for the decades prior. Do you accept that the Arctic Ice may have grown in the 50s 60s and 70s? And what happens if you start plotting after 1989?

  1069. Everything we do releases carbon dioxide, so they want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1070. Lies and propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

  1071. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. So far in 2023 (upto 1st August, 2023) the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) is at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since that point. The climate crisis was 90 years ago. You missed it.

  1083.  @mrunning10  You profanities demean us both. It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020, 2°C above present), and Minoan Warm Periods (Lécuyer, 2018, 4°C above present). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer), far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable. Maybe it was those pesky Neanderthals driving around in their SUVs. That one's been all over the news but if you want a citation I think it was in the 7th December 2022 issue of Nature. The original research was done by some Danish chappy. If you want some really rapid warming look at the CET (Central England Temperature) Instrumental Record between 1690 and 1730 (3°C increase). That won't be reliable enough for you though. Why not try the Dansgaard–Oeschger events? The Dansgaard–Oeschger events were global (Dima et al, 2018).About 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8 °C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. Some researchers believe the Medieval Warm Period was one of these, but I'm not convinced. However, I can provide upwards of 100 citations of science papers that together show the Medieval Warm Period was qualitatively and quantitatively warmer than the current warming, and that it was global in nature, focused around the year 1000. The current warming began around 1700 prior to any large scale combustion of fossil fuels. Also the warming has been small (1°C) and appears to have been largely beneficial. It has not been smooth, for example there was a period of cooling during the 50s, 60s and 70s (NOAA). When many scientists believed the next ice age had begun. Current warming is smaller than predicted by nearly all models (0.13°C per decade since 1979, UAH v6). This will result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°.

  1084. @bruno bond  The D-O events that I cited occurred over a small number of decades and would have been evident to the people of the time without scientific instrumentation, unlike the current warming. The way to think about this for me is not as a conspiracy/scam. We should be more nuanced in our thinking. The Earth's climate is incredibly complicated and multivariable. However, there are some things we could probably agree upon. For example: CO2 is a greenhouse gas. Adding it to the atmosphere should cause some warming. It's after that point that I surmise we would begin to disagree. My research leads me to the view that the Current Warm Period is of extended, low but variable intensity. The climate will change. It cannot remain static. Attempts to mitigate are impossibly costly (and not just in monetary terms) and cannot work. The best approach is to do what humans have always done and adapt.

  1085. @chinvunloong448  The heat energy content of the World's oceans has increased by 400ZJ since 1960. The atmosphere has absorbed about ¹/100 th that amount. There is no way an increase of 100ppm of CO2 into the atmosphere has forced that much heat into the ocean. The atmosphere does not hold enough energy. It is not possible for the energy in the atmosphere to affect the ocean temperature changes seen recently or in the long term. In fact the atmosphere is not trapping more energy as the "greenhouse gas" CO2 increases but is emitting more energy into space as longwave radiation.

  1093. There is no climate crisis. The Earth was warmer in the recent and distant past. It also warmed faster. The extra CO2 in the atmosphere is having a fertilising effect making plants more drought tolerant, and greening the Earth by 15% in the last 20 years.

  1094. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

  1096. Mostly dangerous drivel. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis. This video is anti-humanist.

  1097. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! As an example of good news, Climate Change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, and that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021). Intergovernmental Panel on Climate Change (IPCC) AR6 report, Chapter 11,"Weather and Climate Extreme Events in Changing Climate" concludes that changes in the frequency and intensity of most severe weather events (with corresponding intense rainfall) have not been detected nor can they be attributed to human caused climate change. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Increased CO2 causes this in two ways: it has a direct fertilising effect (the CFE), and it increases drought tolerance by reducing stomata. This greening of the Earth due to CO2 is now "an indisputable fact" (Chen et al, 2024). In fact, 55.15% of those areas greening have been doing so at an accelerated rate since 2001. Since the start of the Industrial Revolution the Earth's primary productivity has increased by more than 30% (Campbell et al, 2017 and Haverd et al, 2020). The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. Banana production has doubled in 20 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). 2023 was another record cereal crop. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022 and 2023 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There is no climate crisis.

The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2.

"Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  1102. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The Earth has greenedDrought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1105. One cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  1106. There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017.

  1109. @franckr6159  The only real change identified is an increase in heat globally but that has not resulted in any of the other calamitous changes foretold. No man made droughts, floods or hurricanes etc. How boring. Even table 12.12 confirms evidence is lacking or the signal is not present, leading to overall low confidence of an emerging signal both for the recent past and out to 2050 even under the most extreme climate modelling (RCP 8.5) of the following: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Severe Wind Storms, Glacier, and Ice Sheets, Tropical Cyclones. And that's under the extreme model 8.5, which is laughable. For more realistic trajectories there will be nothing to see.

  1113. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920. Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, and that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021). Intergovernmental Panel on Climate Change (IPCC) AR6 report, Chapter 11,"Weather and Climate Extreme Events in Changing Climate" concludes that changes in the frequency and intensity of most severe weather events (with corresponding intense rainfall) have not been detected nor can they be attributed to human caused climate change. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). Global temperatures maxed out in 2016 and have been lower ever since (UAH v6 global satellite data). 500 billion tonnes of emissions in that time (14% of all man-made CO2) and no warming. There is no climate crisis.

  1120. @Jc-ms5vv  The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23. Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  1133. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1134. Scare story. CH4 is only 0.00019% (1.9 parts per million) of the atmosphere. Both of its narrow absorption bands occur at wavelengths where H2O is already absorbing substantially. Hence, any radiation that CH4 might absorb has already been absorbed by H2O. With the concentration of water vapour in the atmosphere being between 1,000 and 20,000 times greater than CH4, the effects of CH4 are completely masked by H2O.

  1135. It was nonsense when he said it, and it's nonsense now. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  1137. That's it, Auntie Beeb, get the propaganda in. Severely factors are affecting the Panama Canal. It is the dry season and this has been exasperated by El Niño (both natural events). However there is the management of the lakes that supply water and the canal itself. Also the population has increased by a factor of 5 since 1950, and personal income, and along with it water consumption has ballooned. The water supply comes from the very same lakes that supply the canal. Then mention the Amazon. To assuage your fear of drought can I point out from the latest research "precipitation extremes during the preinstrumental nineteenth century indicate that recent floods and droughts on the Amazon River may have not yet exceeded the range of natural hydroclimatic variability." (Granato-Souza and Stahle, 2023). And let's take a moment to remember The “Forgotten Drought” of 1865, plus "the recent river-level extremes on the Amazon may have been equaled or possibly exceeded during the preinstrumental nineteenth century."

  1138. There is no possible way they can say what the global temperature was in 1941. There will be huge parts of the globe where no measurements will have been taken until the advent of satellite technology towatds the end of the 70s. During the latter half of the nineteenth century reliable records are only really available from parts of Europe, USA and eastern Australia, with a very small number of reliable stations outside of that. Even before 1950 there are essentially no GHCN-Daily stations in South America, India, S. E. Asia, China, Africa, or around the Poles. The graph is a fabrication.

  1142.  @HealingLifeKwikly  It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020), 2°C above present, also Wang et al, 2013, showing the change was at least hemispheric, and Minoan Warm Periods (Lécuyer, 2018, 4°C above present, links Mediterranean to Greenland Ice so at least hemispheric). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer - so don't worry about an ice-free Arctic), far to the north of the current treeline.

  1143. @karlwheatley1244  The big problem for you doomists is peak interglacial warmth is not now but around 8,000 years ago. Proxies show a downward trend to the present day but with an interruption for the Medieval Warm Period (that doomists aren't allowed to believe in) followed by a decent into the The Little Ice Age (which doomists think also didn't exist), and a very slight recovery to the present day still below MWP though. Now I know what you're going to say about the supposed rapid warming over the last century but that's not a fair comparison. That's instrumental, with annual instrumental measurements compared with proxy data, whose the resolution is 200 years. If we smooth out the current data over the last two centuries you'd be lucky to see ½ degree per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century). And let's not forget the Dansgaard–Oeschger events. The Dansgaard–Oeschger events were global (Dima et al, 2018). One about 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8°C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. So shall we say a rate of change about 20°C per century. If that happened now you'd be foaming at the mouth, but it's all within the range of natural events.

  1144. @karlwheatley1244  As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

  1145. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  1147.  @brmadden895  The uptick in warming started before the recent El Niño. None of the most recent changes in SST were predicted. The warming of the ocean is caused by increasing absorption of solar radiation, not increased greenhouse gases, which should cause a reduction in outgoing radiation, but that hasn't happened. The opposite has happened: outgoing longwave radiation has increased.

Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5.

  1158. I'm afraid the Doomsday glacier has lost its doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  1166. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1167. @buzzlightyearlight1247  Would you rather have some actual instrumental data to quote. There is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling with little change in trend around the Equator (NOAA-STARv5 TLT & TMT 1979-2023). Overall the Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming globally. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade, so when you look at actual instrumental records the warming is uneven both spatially and temporally. It's not simple it's complicated. But there's still no climate crisis. I'm going to assume (because you are using Fahrenheit) that you are American, so how about some data from the good ol' US of A? Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. To the start of August the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) was at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since the thirties. The climate crisis was 90 years ago. You missed it.

  1168. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it. The IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence, so 50-50), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence, so 50-50. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising!

Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  1172. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. To the start of August the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) was at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since the thirties. The climate crisis was 90 years ago. You missed it.

  1173. @chrishedlund2688  It's not. This is a scare story about things you cannot see. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis.   The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? These numerical models produce ocean circulations that are far from what we actually observe. These models can't even replicate one of the key physical processes, Convection, in ocean currents "because convection is a small-scale process, it is not captured well in most current models (Jackson et al (2023)" (Rahmstorf, 2024). So they can't model Convection. So they can't model ocean currents.    The most recent research into the AMOC confirms it is not weakening. From a 2024 paper by Terhaar et al published in Nature Communications "Based on the here identified relationship and observation-based estimates of the past air-sea heatflux in the North Atlantic from reanalysis products, the decadal averaged AMOC at 26.5°N has not weakened from 1963 to 2017". So not even close to a tipping point or collapse.   Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. Also the 'Cold Blob' has disappeared from North Atlantic surface temperatures, when annual anomalies for 2013-2023 are compared to the average for the period 1979-2010 (ECMWF ERA5). The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) shows a Sea Surface Temperature departure of over +2°C exactly where the Cold Blob used to be. It may have been there but it's gone. Looking more carefully using NOAA ERSST V5 data for North Atlantic Sea Surface Temperature anomalies (50N-65N, 50W-10W) shows in 1942 a +1°C anomaly declining to -0.7°C in 1992 then rising to almost +1°C in 2010, declining again to -0.6°C in 2010, and of course rising again to +0.75°C in 2023. There are also oscillations in the data back to the 1850s, but there is no trend overall up or down, and no correlation to CO2. The same is true for the heat content in the North Atlantic down to 1000m (Met Office data). No correlation to CO2, just a natural variability. That's the data. The Cold Blob is an artefact.   The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

  1174. @scottekoontz  Have you been using Wikipedia as your data source again? Can I recommend you try the National Solar Observatory? The NSO data shows TSI has been above 1361W/m² (22 year smoothed trend) since the 1950s (at which point of course all warming was supposed to have become man-made). The value is the highest since at least 1500 and the trend line has continued upwards since 1900. Hang on! Is that when the climate was warming as well? Interestingly, the lowest TSI values were centred around 1700 - Little Ice Age, anybody? 2023 saw the highest total solar irradiance of any year this century, using data from Solcast and ECMWF ERA5, and it can be estimated to be the third highest in the entire record. By contrast, ENSO shows no trend or pattern. I refer you to The Royal Netherlands Meteorological Institute (KNMI) Southern Oscillation Index (SOI) – 1882 to Present.

  1176. @chow-chihuang4903  So I give you actual wide-ranging global data that conflicts with your position, and you choose to disregard it, but provide nothing to counter it. How about some more truth to counter your fallacies? The Paleocene-Eocene Thermal Maximum (55mya), a time when the Earth warmed rapidly to temperatures far in excess of today's, only resulted in a noticeable extinction of some benthic foraminifera. That was so small an event it doesn't even show up on a marine extinction intensity chart for the Phanerozoic. There was, in fact, a more general flourishing of life at that point, especially terrestrial. So if you're right we've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition (Grande Coupure). This seems to have been connected with cooling, not warming. Oh dear. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  1177. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence).

  1180. @Hosni Mubarak  You know I can't give you a graph for temperature from a thousand years ago until now because those pesky medieval peasant forgot to take any readings from the wooden thermometers they carried around with them. However, I can give you some proxy data from around the globe. Are you sitting comfortably? "Reconstruction of Environmental Conditions in the Eastern Part of Primorsky Krai (Russian Far East) in the Late Holocene" (Nazarova et al, 2021). It's got some nice data and graphics showing it was warmer by 1.5°C out there in the Far East around the year 1000. And so we move from the Far East to the Indian Ocean: "Modern and sub-fossil corals suggest reduced temperature variability in the eastern pole of the Indian Ocean Dipole during the medieval climate anomaly" (Yudawati et al, 2021). Check out Figure 7. You're going to love it. Whither next? I hear you ask..."Sea surface temperature seasonality in the northern South China Sea during the middle Holocene derived from high resolution Sr/Ca ratios of Tridacna shells" (Zhou et al, 2021). This shows modern (1994-2004) surface temperatures in the South China Sea are colder now than any time in the last 6000 years. Except for a brief interval ~500 years ago (Little Ice Age?), SSTs have been consistently 2-4°C warmer (including Medieval Warm Period) than today since the middle Holocene. And so to the Southern Hemisphere. "6,000-Year Reconstruction of Modified Circumpolar Deep Water Intrusion and Its Effects on Sea Ice and Penguin in the Ross Sea". (Xu et al, 2021). I think my most favourite part of this paper is Figure 3. It shows it was warmer with less sea ice around 1000 years ago. I won't include any data from the North Atlantic because you think the Medieval Warm Period only happened there. I'm enjoying the cherries blossom 🌸.

  1188. So the Arctic is warming faster than anywhere else? Strange. NOAA's Arctic Report Card stated “There is currently no consensus Arctic amplification”. Looking at the European Climate Assessment & Dataset (ecad.eu) for Longyearbyen, Svalbard, the mean of daily mean temperature graph (1958-2020) shows 1958 around -4°C. The temperature then declined rapidly and stayed lower around -6° or -7°C until the mid 1980's (Remember CO2 was rising all the time). By 2015 it rose to around -2.5°C and there it levelled off for the remaining 5 years of the record. So an overall change of +1.5°C in a little over 60 years. If this is the fastest warming on Earth we have nothing to worry about. But it does show how variable climate can be, and the temperature changes have no relationship to the concentration of CO2 in the atmosphere. In the current interglacial Svalbard has been far warmer than today. Using biomarker evidence (for example, the Early Holocene presence of sea creatures unable to survive below fixed warmth thresholds) and glacier melt extent measurements (for example, sea shells buried 6 km inside a glacier), scientists have discovered that much of Arctic Svalbard was about 7°C warmer than today during the Early Holocene, when CO2 concentrations were much lower (near 260 ppm) (Farnsworth et al, 2020. Leopold et al, 2019. van der Bilt et al, 2019. Łacka et al, 2019. Beierlein et al, 2015). Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and the summer (September) coverage trend had stopped declining from 2007 to the present. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades, and May 2023 was the coldest on record in the Arctic. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. Now they're saying ice gone by 2030 or 2050. That's better because the person making that prediction will have moved on, been promoted or retired so there will be no come back when it doesn't happen. The Arctic Ice is still there, and it's stopped shrinking. Anyway the Arctic has already been ice free in the current interglacial. It was certainly warm enough during the Holocene Climatic Optimum, being upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean, far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures when compared to today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. So no ice in the ocean, and the world survived. These changes emerged in the Earth's climate system without any human input.

  1190. More propaganda from Auntie Beeb. Notice the use of the phrase "climate fears". That's the giveaway. The reality of course is there is no evidence we are in a global climate crisis. As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’ This video is fear-mongering without substance. There is no climate crisis, just synthetic climate fear.

  1191. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1193. @Hosni Mubarak  Take a look again at the bar charts. You will see my statement holds true. They are trying not to elucidate their own findings in the text. The Sahara did expand until the 1980's, but their data shows it has contracted since. Then they rely on models to say it's going to expand again. I'm afraid I've come to distrust these climate models as they seem to be 100% wrong in retrospect. But anyway, just have another look at the actual observed data.

The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Mean precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones.

  1197. There is no evidence of a climate crisis. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.

  1199. @ashoakwillow  This scientific consensus idea (usually 97%) comes from a paper by Cook et al in 2013. They reviewed 11,944 climate science papers. 66.4% (7,930) expressed no opinion on 'global warming', and were wrongly discarded. 3% (118) of papers with an opinion rejected GW (Hence the 97% nonsens). The reality was only 24% (2,910) of the papers that they looked at were in support of GW. Only 8% (986) endorsed the view that GW was anthropogenic i.e. man-made. Only ½% (64) supported the IPCC view of AGW. So not 97%, ½%. Because of such perfidy, all climate scientists are now paid and funded to research and agree with AGW. (Look at what happened to Ridd, Curry, Ball, Svenmark, Bellamy). Don't forget to remind Dr John Clauser, Ivan Giaever, Robert Laughlin, and Edward Teller about the consensus, they must have missed the memo. A poll of scientists (meteorologists, physicists, geologists, hydrologists, and climatologists) conducted by the Fairleigh Dickinson University and completed in October 2022 found 59% thought climate change will cause "significant harm", but 39% said either “significant improvement,” “slight improvement,” “no change,” or “slight harm.” That's not a consensus.

  1200. "Insane and dangerous." In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". Antarctic sea ice extent is an unusual weather event dressed up as the end of the world. Antarctic sea ice was at a record maximum in 2015. No one mentioned that as part of a climate crisis. And why we hear about the Arctic? Because there's been no warming there this summer. Summer 2023 is one of the coldest in decades in the Arctic, and May 2023 was the coldest on record there. The Greenland ice sheet surface mass balance (SMB) for the past 11 months is a massive 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010).

  1201. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  1202. 2023 was not the hottest year over large parts of the globe. Asia, Europe, U.S., Oceania, East N. Pacific Region, Hawaiian Region, Arctic, and the Antarctic all enjoyed their highest regional average temperature anomaly in previous years according to data released by NOAA.

  1203. @J4Zonian  Quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" That's between 60°N and 60°S, so pretty much where everyone lives.

  1204. No I'm afraid NZ is no good either! Weather bombs, aargh! Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis.

  1205. I love it when narcissists pontificate about that which they know nothing. Back here in the real world, there has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! As an example of good news, Climate Change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no climate crisis, so men cannot be blamed for something that doesn't exist.

  1206. @astronautical1082  As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8. Indeed the daily noted maximum pH range of 0.7 (Santos et al. 2011) is far greater than the overall change predicted between now and the end of the century.

  1207. @astronautical1082  Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  1208. @astronautical1082  Globally satellite data shows how variable the Earth's climate is with changes up or down of more than 1°C occurring from one year to the next. However, overall the Earth's ecosystems are resilient to these fluctuations, as most species are eurytopic enough to survive these changes.

  1210.  @astronautical1082  Warming events in the Cenozoic do not correlate to mass extinction. The Paleocene-Eocene Thermal Maximum PETM (55mya), a time when the Earth warmed rapidly to temperatures far in excess of today's, only resulted in a noticeable extinction of some benthic foraminifera. That was so small of an event it doesn't even show up on a marine extinction intensity chart for the Phanerozoic. There was, in fact, a more general flourishing of life at that point, especially terrestrial. Many major mammal groups appeared and spread around the globe including hyaenodontids, artiodactyls, perissodactyls, and primates. So if he's right we've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition ("Grande Coupure" = The Great Rupture). This seems to have been connected with cooling (rapid Antarctic glaciation), not warming.

  1211. This climate report is propaganda. The climate attribution studies are based on the relative frequency of daily temperatures in the current climate and in a world without human-caused climate change. Unfortunately, one cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no extra CO2 had been added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests.

Their prognostications never come to pass. They are never confronted for their false prophecy and retire to somewhere warm and coastal that they predicted would be underwater. But people continue to buy into it because we humans pay much more attention to negative messages.

  1215. @Scott Koontz  The Earth has been warmer than the present day on numerous occasions. It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020, 2°C above present), and Minoan Warm Periods (Lécuyer, 2018, 4°C above present). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer), far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable. Maybe it was those pesky Neanderthals driving around in their SUVs. That one's been all over the news but if you want a citation I think it was in the 7th December 2022 issue of Nature. The original research was done by some Danish chappy. If you want some really rapid warming look at the CET (Central England Temperature) Instrumental Record between 1690 and 1730 (3°C increase). That won't be reliable enough for you though. Why not try the Dansgaard–Oeschger events? The Dansgaard–Oeschger events were global (Dima et al, 2018).About 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8 °C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. Some researchers believe the Medieval Warm Period was one of these, but I'm not convinced. However, I can provide upwards of 100 citations of science papers that together show the Medieval Warm Period was qualitatively and quantitatively warmer than the current warming, and that it was global in nature, focused around the year 1000. The current warming began around 1700 prior to any large scale combustion of fossil fuels. Also the warming has been small (1°C) and appears to have been largely beneficial. It has not been smooth, for example there was a period of cooling during the 50s, 60s and 70s (NOAA). When many scientists believed the next ice age had begun. Current warming is smaller than predicted by nearly all models (0.13°C per decade since 1979, UAH v6). This will result in a further 1° of warming by 2100, which can be adapted to, as with the previous 1°, and will indeed have beneficial aspects. They wouldn't tell you all that on Fox!

  1222. The heat energy content of the World's oceans has increased by 400ZJ since 1960. The atmosphere has absorbed about ¹/100 th that amount. There is no way an increase of 100ppm of CO2 into the atmosphere has forced that much heat into the ocean. The atmosphere does not hold enough energy. It is not possible for the energy in the atmosphere to affect the ocean temperature changes seen recently or in the long term. In fact the atmosphere is not trapping more energy as the "greenhouse gas" CO2 increases but is emitting increasing amounts of energy into space as longwave radiation. Nearly all of the energy the ocean receives comes directly from sunlight.

  1223. @HealingLifeKwikly  The current warming trend, and the heat of 2023-2024 is not explained by the rise in gases like CO2. There has been an increase in absorbed solar radiation of around +1W/m²/decade with a record anomaly in 2023 around +1.83W/m² (CERES) or +1.31W/m² (ERA5). This is correlated with total solar irradiance, which reached an all time record-breaking high in 2023 as confirmed by satellite measurement. 90% of this solar radiation is absorbed directly by the ocean. 1% is absorbed by the atmosphere. Changing Greenhouse gas concentration has no effect on this increase in ASR. There is more energy from the Sun reaching the ocean, and this is warming it, and then the ocean is warming the atmosphere, then the atmosphere is radiating this energy away into space at an increasing rate. “The EEI [Earth's Energy Imbalance] trend and 2023 peak are not associated with decreasing outgoing longwave radiation (OLR), as one would expect from increasing greenhouse-gas concentrations" "Instead, OLR has been increasing and largely offsetting even stronger absorbed solar radiation (ASR) anomalies" (Goessling et al., 2024).

  1227. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. So far in 2023 (upto 1st August, 2023) the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) is at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since that point. The climate crisis was 90 years ago. We missed it.

Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022).

NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886.

Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, and that windspeed overland throughout the Northern Hemisphere has been dropping in recent decades. Also the number of intense storms (below 960 mbars) in the Northern Atlantic has fallen sharply since 1990 (Tilinina et al, 2021). Intergovernmental Panel on Climate Change (IPCC) AR6 report, Chapter 11,"Weather and Climate Extreme Events in Changing Climate" concludes that changes in the frequency and intensity of most severe weather events (with corresponding intense rainfall) have not been detected nor can they be attributed to human caused climate change. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded in 2022 (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). Global temperatures maxed out in 2016 and have been lower ever since (UAH v6 global satellite data). 500 billion tonnes of emissions in that time (14% of all man-made CO2) and no warming. There is no climate crisis.

  1231. I'm afraid the Doomsday glacier has lost its doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  1232. @godfreypigott  I'm afraid the paper is a bit of a 'bait and switch', so let's jump to the end as I quote the very last sentence in the paper: "We conclude that TWIS is of limited relevance to upstream flow dynamics in its current configuration, and there appears to be no reason to expect a possible disintegration of the ice shelf to meaningfully impact SLR projections over the next 50 years."

  1233. @godfreypigott  You don't apparently know what I believe. Or why I believe it. Antarctica is not warming, it's cooling, with the evidence showing it has been doing so for at least 40 years, maybe more than 70 (Singh and Polvani, 2020; Bello et al, 2022; Zhang et al, 2022; Zhu et al, 2021). So no "global" warming, and no polar amplification - at least not at the South Pole. Therefore man-made climate change cannot be causing any change in the melt rate of WAIS including Thwaites. Because, you know, it would have to get warmer for the ice to melt. So if there is an increase in the movement of the ice it is coming from heat below, and that is what research suggests - geothermal flux (Dziadek et al, 2021; Martos et al, 2017). If it is hot rock melting ice, there's nothing we can do about it, of course.

I know that Regan, who posted the original comment, can be a bit fruity-abusive with his responses, but he thinks the world is about to end, and that he shouldn't become a father, which is a bit sad, so I sort of understand why he gets a bit uptight.

  1236. @godfreypigott  Climate scientists have a terrible record on predicting. They are lauded for producing the most fanciful visions of the future. I've been hearing these ridiculous predictions all my life: 1958 the Arctic Ocean will be Ice free in one generation. 1967 there will be global famine. 1970 there will be an ice age in the 21st century. 1970 Oceans will be dead in less than a decade. 1971 50 years away from an ice age. 1972 glacial temperatures within a century. 1974 satellites show ice age coming fast. 1978 no end to cooling trend. 1979 ice at North Pole will melt in one lifetime. 1982 environmental catastrophe by 2000. 1988 Maldives underwater in 30 years. 1989 entire nations underwater by 2000. 2000 snowfall has become a thing of the past. 2004 UK climate will become Siberian. Cities will sink into the ocean. 2006 10 years until a point of no return. 2007 if no action 2012 will be too late. Also 2007 Arctic ice free 2010, or 2015, or 2013, or 5 years take your pick. 2008 the Arctic ice sheet would melt away. Also 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 Arctic ice free in 2014. 2012 snow will be gone by 2020. 2013 Methane catastrophe in 2 years because of ice free Arctic. 2018 zero chance of permanent ice in Arctic by 2022. Also 2018 humans to go extinct by 2023 from climate change. 2022 End of Snow predicted again. The people who come up with tosh are described as 'experts' by politicians. In reality, of course, even the IPCC knows, that apart from a little warming here and there, there is no objective evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None. That man-made global climate crisis is always going to happen the day after tomorrow, and it's going to be bad so pay your tithe to eco-priest-politicians.

  1238. In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". Antarctic sea ice extent is an unusual weather event dressed up as the end of the world. Antarctic sea ice was at a record maximum in 2015. No one mentioned that as part of a climate crisis. And why don't we hear about the Arctic? Because there's been no warming there this summer. Summer 2023 is one of the coldest in decades in the Arctic, and May 2023 was the coldest on record there. The Greenland ice sheet surface mass balance (SMB) for the past 11 months is a massive 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). Data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic, and September, 2023 was 4.23. Both of these are higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. But you won't be told any of these facts on the news. They don't fit the story. Because that's what it is make-believe.

  1241. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The most recent rise stopped in August 2023, and has been declining since (NOAA SST v5 monthly). The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  1242. Can I recommend “In Search of Climate Crisis in Greece Using Hydrological Data” (Koutsoyiannis et al, 2023)? It shows since records began in the mid-nineteenth century, there is no long term climate variability. Apart from it being slightly wetter 1990-2020 than 1960-1990.

  1244. Propaganda. When it comes to tipping points this is what the IPCC (Special Report on implications of 1.5C or more warming, Chapter 3) says:“there is little evidence for a tipping point in the transition from perennial to seasonal ice cover. No evidence has been found for irreversibility or tipping points, suggesting that year-round sea ice will return given a suitable climate”. The IPCC also do not believe the melting of the arctic permafrost will cause a tipping point in the release of warming methane gas “the carbon released to the atmosphere from thawing permafrost is projected to be restricted to 0.09–0.19 Gt C yr–1 at 2°C of global warming and to 0.08–0.16 Gt C yr–1 at 1.5°C, which does not indicate a tipping point”. The Earth's climate is a multi input thermodynamic system and will conform to Le Chatelier's Principle.

  1246. @mathieucaron4957  As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe.

Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. Fool.

  1249. She should go back to serving drinks. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1250. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers, we couldn't even notice it.

  1252. @Jess More  I've read plenty and now it's your turn. I'm well aware the NOAA data refers to the Atlantic Basin. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. I notice you misrepresent what I said on the Great Barrier Reef. You missed out "recorded". On the matter of reefs, if you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. As regards extinction, the mathematics is simple, even for someone stupid. The numbers I cite are from IUCN, a source that I imagine even a climate alarmist will accept. The values I use for time and number are set by that organisation. The rate, as previously stated, is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). With temperature, we agree 2016 was the hottest. Looking at UAH v6 global lower atmosphere satellite data from 1979 to the present, the highest temperature was reached in 2016 at 0.7°C above the 1991-2000 temperature average. It has since declined and now (Feb. '23) stands at 0.08°C above the referenced average. In addition I would be interested to know what "average" you are referencing your data points against. N.B. nothing you have written successfully challenged my premise that there is no climate crisis.

  1253. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points - barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

So ask these ppl that you know about the data I have provided in good faith. They should already be aware of it, of course, but wouldn't dare publicise it. It doesn't fit the new eco-cult religion.

So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  1261. Lies and propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). There is no climate crisis.

  1266. @andrew30m  The planet may be warming in places but not as predicted. There's very little else that can be discerned and attributed to humans climatically. Apart from Fire Weather, the UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Mean precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones.

  1267. Sea level appears to be rising at a small 3mm per year. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr; Newlyn, UK 1.94mm/yr. Remember, all linear over many decades, or more than a century. Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked for each set of satellite data (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. There is no relationship to the exponential increase in CO2 in the atmosphere, but can be correlated to multi-decadal oscillations in ocean circulation. It's going to be decades before even your big toe is submerged.

  1268. @gesilsampaioamarantesegund6692  So let's spread some information then. This is from the reputable World Data website "In the years 2001 to 2022, there were only these 3 weather stations in the whole country, which reported continuous temperature values (Caratinga, Irati, Posse). From these weather reports, we have created a long-term development that shows the monthly average temperatures. The average annual temperature was about 21.3 °C in the years after 2001 and about 21.4 °C in the last years before 2022. So it has hardly changed at all in the past 22 years." Get that. There's a lot of coffee but no warming in Brazil.

  1269. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  1271. Britain currently has 39.3 GWh of pumped storage. There are 4 pumped storage stations in Britain. No meaningful storage capacity has been added to the grid since the 1980s, and there is no other large scale energy storage in the country. To cover a cold dark still winter you would need to increase pumped storage capacity by a factor of about 1000 (taking into account pumped storage is about 75% efficient). So we would need to find 4000 suitable locations where a 300 to 400m dam can be built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. Then we would have to build 160 of these every year, year after year, for 25 years. The scale, and the massive cost of storage, by whatever method (pumped storage is one of the cheapest by the way), make it an impossible mission. "Wind droughts" where electrical generation runs at 20% of capacity lasting 100 days or more can be expected once every 50 years. This would see a shortfall of 2TWh at current capacities. 665TWh electricity is projected to come from wind power in 2050 (National Grid). Current wind power 75TWh (2020). 350TWh of Hydrogen storage would exceed by a considerable margin the current annual electrical generation in the UK (~300TWh). It would also be more than 50% of electrical consumption in 2050. Hydrogen storage is also one of the more expensive energy storage strategies at $203/MWh. Pumped storage $131/TWh with gas generated about half of the latter (At 2021 prices researched by Pacific Northwest National Laboratory). Let's look at it another way. The Royal Society recommend the UK should have 100TWh of energy storage (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd.

  1273. Scientists do not essentially write the final version of the IPCC report. It is reverse engineered. The Summary for Policymakers is thrashed out by a very large group of politicos at the UN. Line by line. Remember, these are not scientists, but government lackies. Then they go back to information the scientists gave them and change it. The scientific statements must conform to the political ones, not the other way around. This is policy based evidence making, not evidence based policy making. It's atrocious. The IPCC was set up to find man-made global warming and when you look for something you find it, and indeed they have on the face of it, but when you look deeper you find a dearth of real evidence. Take AR5, that says all observed warming (0.66°C) since 1950 is due to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 is particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative! So many scientists/politicians may have reached a consensus, but the science on which that has been built shows no such agreement.

  1275. Since 1900 the global temperature has increased by 1.3°C. Despite (or maybe because of) that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than that would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should average $71,000 with or without tipping points (Dietz et al, 2021, figure 3). This is the most fortunate time to be alive in the whole of history.

  1276. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence, so 50-50, toss a coin), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence, so 50-50. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising!

  1277. @allan339  Named storms do not measure the amount of energy in the atmosphere, ACE does. 2005: 73 named storms, ACE 670. 2020: 75 named storms, ACE 441.4 (so 2020 had more named storms but they had less energy). The year with the largest ACE value is 1992 (quite some time ago) with 880.3. The problem for climate alarmism is there's no upward trendline in the data. It appears almost random over the years (although it may be related to the AMO). If you're interested in year by year data, and you haven't seen it yet, try CSU Department of Science Tropical Meteorology Project.

  1290. The mirage of a climate catastrophe has hardened into a delusion. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1292. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23. Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Zhang (2021) shows there is no trend for Arctic sea ice volume since at least 2010, and observes that ice draft increased from 1995 onwards. Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming.

  1294. "Insane and dangerous." At the height of northern summer in July, of 176 countries in the Northern Hemisphere, only China and Albania broke their national records, which is a little disappointing considering all the scary reporting. It's more what you would expect from a slowly warming world (~0.1°C per decade UAHv6 and NOAA-STARv5) which is of course what we're living in. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.

  1295. One cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  1296. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

The Royal Society recommend the UK should have 100TWh of energy storage (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd.

  1301. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve).

  1302. Since 1900 the global temperature has increased by 1.3°C. Despite (or maybe because of) that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than that would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world! There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should average $71,000 with or without tipping points (Dietz et al, 2021, figure 3). This is the most fortunate time to be alive in the whole of history.

  1303. As regards the melting of Arctic Ice, the records nearly always seem to start in 1979. Strange that, considering it was a year of record extent for Arctic Ice. Even so, data from NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. How inconvenient! Didn't someone predict in 2007 Arctic ice free by 2010, or 2015, or 2013, or in 5 years? Or was it in 2008 the Arctic ice sheet would melt away. Also predicted in 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 prediction: Arctic ice free in 2014. 2012 prediction: snow will be gone by 2020. And 2013 star prediction: Methane catastrophe in 2 years because of ice free Arctic. 2018 prediction: zero chance of permanent ice in Arctic by 2022. The Arctic Ice is still there, and it's stopped shrinking. If you consider global sea ice cover, it was basically flat from 1981 to 2008, rose until 2010, stayed level until 2015, dropped until 2018, and then rebounded almost all the way back to the 1990-2000 average. Nobody predicted theses changes, nor can they explain them. The changes have no relationship to the concentration of CO2 in the atmosphere. The climate crisis/emergency/apocalypse is make-believe. Multiyear ice is an unproductive habitat as far as marine organisms are concerned: first year (seasonal) ice over continental shelves is the most productive and this is where the vast majority of polar bears, seals, fish, whales, and sea birds are found. Therefore the decline of extremely thick multiyear ice (>4 years old) could be seen as an unconcerning development with regards to the wildlife in the region, especially since 2-3 year old ice that can be used as a resting/hunting platform for seals and polar bears hasn't declined in summer since 2007. In fact, biologically, the Arctic is in good shape with all its regions showing a positive trend in primary productivity over an extended period (2003-2022). This has resulted in more food for seals, walruses, bowhead whales and polar bears, which are hence maintaining or expanding their populations. There's no "death spiral" in the region as some people reported. In fact, there is, as I say, no evidence of any crisis/emergency. That is silly nonsense designed to scare people.

  1304. IPCC's (Scenario A) modelled predictions are junk. Back in 1990 the IPCC predicted a warming of 0.30-0.34°C per decade. Of course we've only had about 0.1°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it! But there is still no crisis just an unexciting set of observations. All the climate models run too hot, 100% of them. The attribution of all warming to human activity by the IPCC is junk science as well. Take AR5: that says all observed warming (0.66°C) since 1950 is due solely to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 is particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative!!! So many scientists/politicians may have reached a consensus, but the science on which that has been built shows no such agreement.

  1305. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1306. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1311. @chrismckellar9350  You can beg as much as you like. It won't make any difference to the facts. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high. With Methane (CH4), it is only 0.00019% (1.9 parts per million) of the atmosphere. Both of its narrow absorption bands occur at wavelengths where H2O is already absorbing substantially. Hence, any radiation that CH4 might absorb has already been absorbed by H2O. With the concentration of water vapour in the atmosphere being between 1,000 and 20,000 times greater than CH4, the effects of CH4 are completely masked by H2O.

  1313. @MegaDeano1963  The EPA website referring to Heat Islands states "in the United States, the heat island effect results in daytime temperatures in urban areas about 1–7°F higher than temperatures in outlying areas and nighttime temperatures about 2–5°F higher." However even this is an underestimate as the Urban Heat Island effect can result in temperatures 10°F (5°C) higher during the day (Scientific American, 2019). This alone explains any record high temperatures. And as I'm sure you're aware, Las Vegas is in a desert, which is characterised by long summers and extremely high temperatures. And that's exactly what's happening. There's nothing unusual or unexpected here. Hope this helps.

  1314. @StLouisBear  Nevermind. In a world that's 3°C warmer by the end of the century, it has been estimated that incomes will be between 1.9% (Tol, 2024) and 3.1% lower (Nordhaus) than the would otherwise have been. However the UN estimates that total incomes will have increased by 450% by 2100. If the effects of climate are included we will only be 440% or 435% richer! Oh my God, it's the end of the world!

  1318. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million, the lowest since 1998 (NIFC), and 3% of the burn in the 1900s. Annual share of the total land area burnt by wildfires in the US went from 0.6% (2012) to 0.4% (2024)(GWIS/FAO UN). There's basically no increasing trend in the data. The areas burnt are comparatively tiny.

The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)."

  1323. @abody499  The Greenland Ice Sheet contains about 2.9 million cubic kilometers of ice (NSIDC). Using the formula M=Vd (and assuming density of glacier ice 0.9167 Gt/km³), the mass of GrIS is approximately 2.7 million Gt. If we use the figure of annual loss of 270 Gt, we get 0.01%, or 10,000 years, so around 12,024 AD. The problem is the average figure of 270 Gt (NASA data 2002-2023, 0.8mm/year sea-level rise, so a non-problem). That average value and the data range used gives no understanding of the changes taking place. Prior to 2000 GrIS was not losing mass. From 2002 to 2012 mass loss accelerated, then from 2012 to the present mass loss trend decelerated (85 Gt, 2021). The changes aren't linear they are sinusoidal and are related to the North Atlantic Oscillation, not the the concentration of CO2 in the atmosphere.

  1324. @abody499  Antarctic ice sheet (1992-2020) annual loss was 90Gt/yr. It's total mass is 24,380,000 Gt (24380000000000000 tons), so it loses less than 0.0004% of its mass annually, which I think you could reasonably round down to zero. It contributes 0.36mm to sea-level rise per year (that's essentially nothing as well). At the current rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. That ice is here to stay. There's a bit of a problem with the accelerating ice loss in Antarctica idea. It's not accelerating. If you want to dig down to the actual data, that is. Just so we're clear, I'm referring to the paper entitled "Mass balance of the Greenland and Antarctic ice sheets from 1992 to 2020" by Otosaka et al, 2023. Can I direct you to table 2, and the text below it? If we include the APIS in "continental" (although I wouldn't) there's no pattern with a slight loss overall - neglible. EAIS, by far the larger of the continent's ice caps, both by surface and volume, hasn't lost mass. It has gained mass, but again it's neglible. So that leaves us with WAIS. It's only WAIS that's driving the mass loss from Antarctica, and you can see that from the Figure 4 graph. Figure 4 and Table 2 show there is a step up in mass loss around 2007. You might want to call that an acceleration. However there's a deceleration from 2017 or at least a noticeable reduction in the rate of annual ice mass loss for the period 2017-2020 when compared to 2012-2016. So accelerating then decelerating. The Antarctic Ice sheet is massive and it's never going to melt on the timescale of human civilisation. Coming back to what we know though about Antarctica, you doomster cult followers have got a problem with Antarctica, haven't you? It's ice shelves are expanding by mass and volume, plus the continent has cooled very significantly in the past 40 years. But a small part (WAIS) of the ice cap is losing mass. Something is making the WAIS melt it would appear, and it cannot be the increasingly colder climate. Maybe geothermal activity? Or maybe a change in wind direction from the Pacific? There's evidence for both. I don't know, but the climate has to warm for the ice to melt significantly and it isn't.

  1325. @abody499  The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022 and 2023 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  1329. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since at least 2005. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The all-time high temperature records set in most states occurred in the first half of the twentieth century.

  1333. If you took away El Niño, a record increase in Total Solar Irradiance, and the Tonga eruption (all natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP. There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  1336. So a few decades ago it was drier. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no genera have become extinct in the last 500 years. Global temperatures maxed out in 2016 and have been lower ever since (UAH v6 global satellite data). 500 billion tonnes of emissions in that time, and no warming. There is no climate crisis.

  1339. If you took away El Niño and Tonga (both natural events) there would be nothing to see. Sea surface temperatures were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two.

  1341. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886.

Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis. This video is anti-humanist.

  1344. @J  I do appreciate the length of your response and any time you took in its compilation. But if I'm cherry-picking then so are you, but you are picking different cherries. I must also point out the Guardian newspaper is hardly an unbiased scientific source, and really should be put to one side. I think it's reasonable to say the sources I have used are scientifically reputable, and most of the references are global in nature. Surely these must be taken into account for a rounded picture of what may or may not be occurring.

  1345. @J  Thank you for the lesson in hyperbole, but current warming is smaller than predicted by nearly all models (0.13°C per decade since 1979, UAH v6) so around ½°C for the past 40 years (but no overall warming over the past 8 - sorry couldn't resist that cherry 🍒). This will result in a further 1° of warming by 2100, which can be adapted to, as with the previous 1°. 😀
    1
  1346. @J  The exchange between us does not have to be abusive and personal on your part. Let's stick to the facts and try to have a reasonable discussion. What was it about the UAH v6 satellite data that I referred to did you consider to be untrue?
    1
  1347. @J  Even if I was to accept your data, which I don't because it has been fiddled with repeatedly, for example the years with the warmest average maxima remain the 1930s, and the recent apparent warming comes from an increase in the minima not the maxima (i.e. there's less of a range, it's just got a bit milder), but let's just say, for the sake of argument, I do accept it. If we are in a period of warming, you would expect the most recent years to be the hottest. Also your range only goes back to 1880, prior to that was the Little Ice Age, and prior to that was the Medieval Warm Period which was warmer than the present, and before that were even warmer periods: Roman, Minoan, Holocene Climatic Optimum, Eemian Interglacial, etc, etc....
    1
  1348. @J  Now, now, there is no need to get personal. You could at least identify some of the lies? Medieval Warm Period was warmer - do you consider that to be a lie?
    1
  1349. @William S  I am presuming from your response, although I may be wrong, that we would agree that 2,000 years ago and further back, their were periods of warming that were of a similar (or perhaps greater) rate and magnitude as the present. Presumably those periods of warming (e.g. Minoan Warm Period and Holocene Climatic Optimum) were natural, and so the climate of the Earth in the current interglacial is capable of producing periods of warming like the current one without any external anthropogenic forcing. You make an interesting point with reference to proxies. These have to made use of, of course, because there were no Chinese peasants or English serfs wandering around with thermometers in their pockets. However, even the proxies cherry-picked by the IPCC fail to show a consistent pattern of warming especially in the Southern Hemisphere for the Current Warm Period (AR4, 6.6.2, fig.6.12). Even in adjacent locations (Northern and Southern Patagonia) the temperatures are heading in opposite directions. If we are using proxies though and arguing over the Medieval Warm Period being warmer than the present and not limited to a region, I would refer you to a 2010 paper by Ljungqvist: "A new reconstruction of temperature variability in the extra-tropical Northern Hemisphere during the last two millennia. Geografiska Annaler Series A 92: 339-351." It uses 30 proxies, and shows rapid warming around 1000 and 1700. It also shows that the Roman and Medieval Warm Period temperatures exceeded the Current Warm Period. It also suggests the effects were hemispheric or even global. This ties in nicely with Antarctic Law Dome d18O ice core dataset showing a strong Medieval Warm Period signal but nothing much for the present. Incidentally I can cite upwards of 100 science papers from across the globe that show the Medieval Warm Period was warmer than the present. When you look at actual instrumental records the warming is uneven both spatially and temporally. There is very little warming around the tropics. The Canadian Arctic has warmed. Continental Antarctica (excluding the Peninsula) has cooled significantly. America has by far the best instrumental data, and it shows overall the South East cooled in the last 120 years. Though that sentence doesn't do justice to the climate's variability. Data from NOAA (2021) shows uneven warming in the twentieth century focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day.

  1350. @J  If I can cite scores of science papers that show the Medieval Warm Period was warmer than the Current Warm Period, there is no unanimity. Remember these span the globe and show the climate on every continent and in the oceans. No, the warming is not global: the Arctic warms, the Antarctic cools. The warming is marginal and not accelerating. Maybe another degree by the end of the century. Please be aware that the IPCC's (Scenario A) modelled predictions are junk. Back in 1990 they predicted a warming of 0.30-0.34°C per decade. Of course we've only had 0.13°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it! But there is still no crisis just an unexciting set of observations. You say we know the cause is human greenhouse gases, well if the "we" includes the IPCC that's junk science as well. Take AR5: that says all observed warming (0.66°C) since 1950 is due solely to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 is particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative!!! So many scientists/politicians may have reached a consensus, but the science on which that has been built shows no such agreement.

  1353. @J  There you go again. More unpleasant personal remarks. You have to do that because you cannot successfully combat any of the data I provided for your perusal. It must be unsettling for you. Along with your insults, you have had to resort to an argument from authority. Arguments from authority are based on the idea that a person should conform to the opinion of a perceived authority or authoritative group. Humans have been shown to feel strong emotional pressure to conform to authorities and majority positions. Is that your case? Interestingly, when over 100 scientists published a booklet (Hundert Autoren gegen Einstein, 1931) against Einstein and his work on relativity, he responded "If I were wrong, it would only take one." Scientists have got things very wrong on many things: smoking, pesticides, and more worryingly eugenics, which was widely accepted in the first half of the twentieth century. It is much better to remain sceptical.

All those real climate scientists who worked on all that lovely research. Mmm. Delicious. Suck it up, goose.

  1355. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  1356. @Dominick Cizek  Hmm. All those CAPITAL LETTERS at the start is a bit "In the beginning..." However, the National Oceanic and Atmospheric Administration (NOAA) maintains a tidal gauge just offshore from Miami on Virginia Key. That tidal gauge shows sea level at Miami is rising even more slowly than the global average of 1.2 inches per decade. So Miami shows no signs of acceleration in sea level rise. In God we trust. Everybody else brings data.

  1357. @Erndea  The oil companies didn't know what was going to happen in the 1970's. Nobody did, and frankly nobody does. They had done some scientific research and had constructed some models, which they correctly treated with caution. As everyone should do, as all the subsequent models have been shown not to work, and vary enormously in their output. The problem is you believe these climate models to be Truth Machines. They are not.

  1359. ​@paulnewman2000 Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating nor decelerating. The trend is linear. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size.

  1360. @kurtilein3  In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". Antarctic sea ice extent was an unusual weather event dressed up as the end of the world. Antarctic sea ice was at a record maximum in 2015. No one mentioned that as part of a climate crisis. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.

  1364. Two weeks after this bull, Europe is in a cold wave with negative temperature anomalies. Frosts are forecast for southern Germany, and people will need to put their heating on in August. Cool, damp and dull for the foreseeable future. At the height of northern summer so far this July of 176 countries in the Northern Hemisphere, only China and Albania have broken their national records, which is a little disappointing considering all the scary reporting. It's more what you would expect from a slowly warming world (~0.1°C per decade UAHv6) which is of course what we're living in. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. It's the "record" word that's most important here. Although Phoenix was incorporated in 1881, NOAA only has continuous data from around 1940. So recorded history for Phoenix in this instance is about 80 years (not that long climatically) and the record for 1930s (when heatwaves were worse) is mostly incomplete. Also Phoenix's population has expanded exponentially in that time from a few tens of thousands to a few million. This has dramatically increased the Urban Heat Island effect resulting in temperatures 10°F (5°C) higher during the day (Scientific American, 2019). This alone explains the record high temperatures. As I'm sure everyone is aware, Phoenix is in the Sonoran desert, which is characterised by long summers and extremely high temperatures. And that's exactly what's happening. There's nothing unusual or unexpected here. The news story is purposely catatrophising the weather to unnecessarily scare people into changing their way of life. There is no global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  1372. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Increased CO2 causes this in two ways: it has a direct fertilising effect (the CFE), and it increases drought tolerance by reducing stomata. This greening of the Earth due to CO2 is now "an indisputable fact" (Chen et al, 2024). In fact, 55.15% of those areas greening have been doing so at an accelerated rate since 2001. Since the start of the Industrial Revolution the Earth's primary productivity has increased by more than 30% (Campbell et al, 2017 and Haverd et al, 2020). Zhu, Piao, & Myneni, 2016 calculate that 70% of Earth’s global greening in the modern period is due to CO2 and only about 13% is due to fertilizer and land use changes by humans. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests. Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. Banana production has doubled in 20 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). 2023 was another record cereal crop.

  1373. This hasn't aged well. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. Deserts have shrunk considerably since the 1980's and the Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1378. There is no climate crisis. There isn't too much carbon dioxide in the atmosphere. Carbon dioxide is the most essential gas in the atmosphere, and it exists as only a trace. If the levels were much lower all complex life on the planet would disappear. Removing it from the atmosphere is hubristic madness.

  1379. @bruno bond  Below 150ppm plants and, therefore animals will die. This nearly happened 19,000 years ago. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886.

Oh, deserts like the Sahara have shrunk considerably since the 1980's and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years.

  1380. @h0rn3d_h1st0r1an  Before the British, the Zamindars were warlords who would rapaciously exploit their own holdings whilst raiding and degrading the lands of other Zamindars. The British pacified them, and brought the rule of law. Besides which all this was just an evolution of the jagirdar system used by the Mughals and the Sultanate of Delhi before that. These agrarian parasites were already there. But they were Indian, not British. This Indian elite creamed off 15% of the national income under the Mughals, and after the latter's collapse, between 1750 and 1810, the despotic indigenous elite extracted upto 50% of production so they could indulge in warfare. Despicable. The British stopped all that, and at the height of the Raj, the Zamindars only took 3% for themselves. The Indians were better off when India was run by the British.

  1382. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. So far in 2023 (upto 1st August, 2023) the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) is at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since that point. The climate crisis was 90 years ago. You missed it.

  1383. @Jc-ms5vv  The Petm only resulted in a noticeable extinction of some benthic foraminifera. That was so small an event it doesn't even show up on a marine extinction intensity chart for the Phanerozoic. There was, in fact, a more general flourishing of life at that point, especially terrestrial. We've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition (Grande Coupure). This seems to have been connected with cooling, not warming. Oh dear.

  1386. ​@allangibson8494 To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. "Florida Current transport observations reveal four decades of steady state" Volkov et al, 2024 (published in Nature). This paper shows that a key component of AMOC, the Florida Current, has remained remarkably steady for over 40 years. There is no climate crisis. The North Atlantic current has doubled its velocity over the course of a quarter of century (Oziel et al, 2020). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions with claims of 95% certainty that the AMOC will collapse by the end of the century. Come on! Really? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The North Atlantic ocean has cooled and warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008. See Figure 8 in the paper). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

  1392. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  1403. @anabolicamaranth7140  The video itself is cherry picking as I have demonstrated with my more expansive data. This video obscures the truth. Go back to the source, the Norwegian Meteorological Office (Selima), to try to get to the bottom of this. I suggest everyone check out their data. Ny-ålesund data for maximum annual temperatures shows no trend since records began in 1969. It has not got hotter. However, the minimum annual temperatures has increased, so the winters have become milder (but still extremely cold). The increase in the annual minimum temperature occurred over 20 years, but this trend stopped around 2006. To find a longer term view on Svalbard you need to look up other weather stations, for example Longyearbyen + Svalbard Lufthavn. Looking at say 1950 to the present shows no trend in the maximum temperatures. The minima dropped quite considerably from the later 50s. The 60s and 70s had an intensely cold trend of minima. It then warmed in the 80s/90s and from 2005 levelled off. So overall the swings in temperature on Svalbard during the year have become less extreme. Very roughly, it hasn't got hotter, but the winters, which got very much colder, became less cold, now they have stopped getting less cold since about 2005. Svalbard's climate became milder, less extreme than compared to the 60s and 70s, but not hotter. That process of amelioration has stopped. These changes are uncorrelated to the level of CO2 in the atmosphere.

  1406. @Mike-zx1kx  The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS), and that is despite reports of supposed repeated bleaching, despite starfish predation and despite any bad weather. It should be renamed the Greatest Barrier Reef! If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  1407. @Mike-zx1kx  A more balanced review of the data cannot support the assertion that there has been a major global loss of coral in the recent past, and nor can this loss be projected into the future. Any claims made prior to 2000 need to be treated with caution due to the huge margins of uncertainty in the data. There is also a refusal to focus on any positive points to maintain a sense of balance. For example, although GCRMN claimed a 14% coral loss between 2008 and 2019, it failed to mention that there was an apparent increase of a similar amount between 2000 and 2008. This seems disingenuous. Taking a look at regional data, the different areas show no relationship to each other or to a changing climate, or to the the concentration of CO2 in the atmosphere. Returning to whole world data still does not validate the idea that there has been a major drop in coral cover. There may have been a diminution of 7% from 2000–19, but this must be treated with some caution because the stated error margin is of similar size to the difference. Also one should consider natural variability at around 10% – higher than the difference between 2000 and 2019. I just went back and had a look at some GCRMN data by region, looking for a signal for bleaching. I noticed East Asia (the most important region for coral at 30.1% of global coral) was unaffected. In fact, coverage increased. So not global bleaching. Then I looked at AIMS' GBR LTMP data, which is more valuable than GCRMN, because of its longer time frame and more consistent methodology. Normalised coral cover for the Great Barrier Reef remained little changed around 1998, staying near 0.20 for a few years either side. AIMS stated in reference to the 1998 bleaching ‘most reefs recovered fully'. So not a global bleaching. For reference the 2022 figure for coverage on GBR is 0.34. That's quite a rise. Looking at their graph it's shot up since 2011 (despite four 'bleaching' events). In fact the last 3 years are record cover.

  1408. @Mike-zx1kx  A more balanced review of the data cannot support the assertion that there has been a major global loss of coral in the recent past, and nor can this loss be projected into the future. Any claims made prior to 2000 need to be treated with caution due to the huge margins of uncertainty in the data. There is also a refusal to focus on any positive points to maintain a sense of balance. For example, although GCRMN claimed a 14% coral loss between 2008 and 2019, it failed to mention that there was an apparent increase of a similar amount between 2000 and 2008. This seems disingenuous. Taking a look at regional data, the different areas show no relationship to each other or to a changing climate, or to the the concentration of CO2 in the atmosphere. Returning to whole world data still does not validate the idea that there has been a major drop in coral cover. There may have been a diminution of 7% from 2000–19, but this must be treated with some caution because the stated error margin is of similar size to the difference. Also one should consider natural variability at around 10% – higher than the difference between 2000 and 2019. I just went back and had a look at some GCRMN data by region, looking for a signal for bleaching. I noticed East Asia (the most important region for coral at 30.1% of global coral) was unaffected. In fact, coverage increased. So not global bleaching. Then I looked at AIMS' GBR LTMP data, which is more valuable than GCRMN, because of its longer time frame and more consistent methodology. Normalised coral cover for the Great Barrier Reef remained little changed around 1998, staying near 0.20 for a few years either side. AIMS stated in reference to the 1998 bleaching ‘most reefs recovered fully'. So not a global bleaching. For reference the 2022 figure for coverage on GBR is 0.34. That's quite a rise. Looking at their graph it's shot up since 2011 (despite four 'bleaching' events). In fact the last 3 years are record cover.

  1409. @Mike-zx1kx  Does "a few" mean less than 40 to you? The AIMS Long-term Monitoring Programme (LTMP) data for the GBR (Great Barrier Reef) started in 1985. At the start of the data sequence for the whole GBR cover was 25% in 1986. It reached a low point in 2011 of 12%. In 2022, the LTMP found record high coral cover on the GBR of 34% coral cover on the seabed of the coral reefs monitored. Northern region reached a low point in 2016. However, it has since completely recovered, with coral cover now at double the 2016 level, and recording record cover. The Central region has experienced a greater degree of fluctuation, but is also now at record high coral cover. The Southern region is now at record equalling coral cover, three times higher than at its low point in 2011. Every region is at record-equalling high coral cover, once uncertainty estimates are taken into account. The reef always recovers strongly. And it's got nothing to do with CO2. Increases in bleaching events has not prevented rapid and record increases in coral cover. AIMS states "Percent hard coral cover is one standard measure of reef condition recorded by scientists worldwide, it provides a simple and robust measure of reef health" with that in mind, and it being such a robust measure, let's just say it loud and clear: hard coral cover is at record-equalling levels in all three sectors of the GBR. Crown of Thorns Starfish are also a non-problem. Northern: no starfish or no outbreak on all reefs. Central: no starfish or no outbreaks. Southern: out of 30 reefs, 27 had no starfish or no outbreaks. And once more, oh yes, there is record hard coral cover on the Great Barrier Reef. And that is a robust measure of reef health. What a robust reef!

  1410. @Mike-zx1kx  Who do you think you are? Vishnu? I'm not deflecting from the core issue. The core issue is that there is no objective data that we are in a global climate crisis. The video was about the Arctic, so I present data that shows summer ice extent has stopped decreasing and maximum temperatures have stopped increasing, and they are unrelated to CO2, so you deflect and start wittering on about coral reefs so i quote data that shows when it comes to coral, again its variation is unrelated to CO2. Like I say, there is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones. The reality is of course people are living longer healthier wealthier lives, food production is at record levels, and the Earth is greening. This is the best time to be alive in human history.

  1411. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936, Arizona was not one of them. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. So far in 2023 (upto 1st August, 2023) the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) is at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since that point. The climate crisis was 90 years ago. You missed it.

  1412. Total nonsense. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating or decelerating. The trend is linear. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  1414. @ThorirEy  This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  1419. There is no climate breakdown. Let's talk numbers. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  1420. @gardenjoy5223  Fair enough. No temperature records have been broken in Europe. Rome was supposed to have broken its, but it wasn't as hot as in 1841. Greece is nowhere near its record of 48°C set way back in 1977. IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There's no trend for wildfires in Greece. 2021 was the highest and 2022 one of the lowest.

  1424. Weather events are not climate. The severity of individual weather events cannot be attributed to factors implicated in man-made climate change. Global burned area has decreased by one quarter this century! For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). There is no climate crisis...there isn't even any evidence for it.

  1425. It's a floodplain so it will flood. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1429. The Royal Society recommend the UK should have 100TWh of energy storage by 2050 (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. A typical pumped storage facility has a 300 to 400m dam built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the less than 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the whole Earth going Net Zero. Good luck with that.

  1431. @Strangemagic  Carbon dioxide I think we can agree is a greenhouse gas. However, its addition to the atmosphere has the effect on the Earth's energy budget of a few Watts per metre squared. This is marginal and less than the error range for the estimation of the effect for the main greenhouse gas - water vapour. It is also logarithmic in its action, and the more we add, the less effect it has. As regards World population, the use of fossil fuels has increased the efficiency of farming in a variety of ways. Also, the extra CO2 in the atmosphere has a fertilising effect, causing the Earth to green dramatically over the past few decades and helping make plants drought tolerant and increase yields. These factors have resulted in wondrous human flourishing. You are less likely to starve now than at any time in human history.

  1432. Channel 4 propaganda. Don't look at the Arctic! Look at the Antarctic! The Greenland surface mass balance (SMB) increase for the year 2022-23 was a massive - and well above 1981-2010 average - 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). Greenland has been cooling since 2012. No, no. We're not reporting that. That would give the story balance.

  1433. Propaganda. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.

  1434. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points - barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should $71,000 with or without tipping points (Dietz etc al, 2021). This is the most fortunate time to be alive in the whole of history.

Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years. It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. There is no climate crisis.

When you use data from the World Bank and global insurance, and try to measure the cost to society of climate change, you find the cost is minimal and diminishing. Global weather losses as a percentage of Global GDP sank from 0.25% to below 0.20% between 1990 and 2022. Based on data published in the Lancet in 2019, GDP percentage Climate-Related Disaster Losses have declined in all global income categories, with the most noticeable declines in the lower income countries (Watts et al., 2019).

  1438. The Arctic is not warming faster than the rate of anything. Going back to the source data for Svalbard in the high Arctic, the Norwegian Meteorological Office (Seklima), gets to the bottom of this. I suggest everyone check out their data. The Ny-ålesund site data for maximum annual temperatures shows no trend since records began in 1969. It has not got hotter. However, the minimum annual temperatures has increased, so the winters have become milder (but still extremely cold). The increase in the annual minimum temperature occurred over 20 years, but this trend stopped around 2006. To find a longer term view on Svalbard you need to look up other weather stations, for example Longyearbyen + Svalbard Lufthavn. Looking at say 1950 to the present shows no trend in the maximum temperatures. The minima dropped quite considerably from the later 50s. The 60s and 70s had an intensely cold trend of minima. It then warmed in the 80s/90s and from 2005 levelled off. So overall the swings in temperature on Svalbard during the year have become less extreme. Very roughly, it hasn't got hotter, but the winters, which got very much colder, became less cold, now they have stopped getting less cold since about 2005. Svalbard's climate became milder, less extreme than compared to the 60s and 70s, but not hotter. That process of amelioration has stopped. These changes are uncorrelated to the level of CO2 in the atmosphere.

Also the 'we have' gives it a nice cultic flavour, or am I being sarcastic? Nevertheless, your f-bomb mountain requires a little erosion. I have two pieces of evidence you may find elucidating relating to my comment on 'no warming'. Firstly, satellite data from 1979 onwards (UAH v6) shows hesitant global warming averaging 0.16°C per decade. In itself nothing to be concerned about. However, over the last 8 years there has been no overall warming in the data. As a second example, you might also want to take a look at the state of the art US Climate Reference Network (run by NOAA). It shows no warming overall since 2005 when they started recording. In fact it shows cooling of about -0.61°C.

  1444.  @ImproveYourMagic  Earth’s automatic reaction appears to be rather positive. Life thrives in a warmer world with extra CO2 to fertilise plants.

  1445. @ImproveYourMagic  There's no empirical evidence that any of this is going to happen. The ECS derived empirically is about 1.8°C (maybe less), and that's if we double the ppm for CO2, and that's not going to happen for a long time, if at all. Besides all that we're living on an "icehouse" Earth, and this Ice Age is the coldest the Earth has been in 450 million years. For the vast majority of the Earth’s history it was much warmer than today, and plants thrived in the extra warmth.

  1446. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1447. @jaspercaelan4998  There is no objective observational evidence that we are living in a global climate crisis. Even the biased UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Mean precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones.

  1452. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we could even notice it.

  1458. Weather events are not climate. The severity of individual weather events cannot be attributed to factors implicated in man-made climate change. One cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no GHGs are added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  1459. Always remember to virtue signal. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. If we look at the Global Coral Reef Monitoring Network (GCRMN) data (which isn't ideal for various reasons) the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth.

  1462. @AndTecks  The sources are included in the original comment: USCRN (US Climate Reference Network), and UAHv6 University Alabama Huntsville satellite data version 6). Further to that, there is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling with little change in trend around the Equator (NOAA-STARv5 TLT & TMT 1979-2023). Overall the Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming globally. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade, so when you look at actual instrumental records the warming is uneven both spatially and temporally.

  1464. @Lotsoftrains2192  The British took a continent of people in which life for everybody was ugly brutish and short, plagued by the prospect of unremitting warfare, and the arbitrary exercise of power by self-appointed despots. Britain changed India into a land at Independence gifted with internal peace, the Law, Democracy, property rights, a growing population with improving health and education, a modern transportation system, and a developing economy. You're welcome. It took the Indians another 50 years before they made any real progress when left to their own devices. Largely because they were foolish enough to colonise themselves with another, much worse form of western imperialism, planned economy Marxism. The Indians were truly fortunate to have the British as the facilitators of their development for as long as they did. The fact that such a small number of British could sit atop a system that governed such a huge mass of humanity is a credit to British history. It is a demonstration of the energy and dynamism of the British nation at that time, and totally in keeping with the ways in which pre-industrial societies were organised. Of course it was a pyramid, but it was one overlaid on an Indian society in which it had always been thought proper that a member of higher caste could exploit, abuse and even murder the members of a lower caste as the whim took them. Before the British, the Zamindars were warlords who would rapaciously exploit their own holdings whilst raiding and degrading the lands of other Zamindars. The British pacified them, and brought the rule of law. Besides which all this was just an evolution of the jagirdar system used by the Mughals and the Sultanate of Delhi before that. These agrarian parasites were already there. But they were Indian, not British. This Indian elite creamed off 15% of the national income under the Mughals, and after the latter's collapse, between 1750 and 1810, the despotic indigenous elite extracted upto 50% of production so they could indulge in warfare. Despicable. The British stopped all that, and at the height of the Raj, the Zamindars only took 3% for themselves.   The idea that the British somehow drained the life out of India is without statistical foundation. The colonial government was a very small part of economy, and any monies sent out of the country were easily offset by India's trade surplus. India had attracted £380 million in British capital by 1913, £23 billion in today’s money. But Home charges in 1913, the so-called drain from India to Britain, were only £ 11 million, tiny by comparison.

  1467. @Zenger Gazette  I am certainly not denying that the climate changes. It will change even if unperturbed by extraneous influences. I'm not even denying that CO2 is a greenhouse gas. But its effects are turning out to be modest, and ones to which we can adapt. Our 'cures' may turn out to be worse than the 'disease'. I will assume your point about me drinking dirty water was flippancy.
    1
  1468. @Zenger Gazette  I quite agree that we should try to provide clean water, nutritious food, and a pleasant environment for our fellows. To do this requires wealth, the development of technology, and the production of cheap and reliable energy. At present and for the foreseeable future, this will require the consumption of huge amounts of fossil fuels globally. There's no getting away from that. However, the actual warming and the subsequent effects caused by this appears - from my perspective at least - to be marginal, and some may even be beneficial.

  1469. There is no climate crisis. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis.

  1470. @swiftlytiltingplanet8481  If hurricanes had increased by 8% per decade since 1850 that would mean there were nearly four times the number hurricanes now as there were then. This would certainly have been noticed and been plain to see, and contradicts the statement I quoted from NOAA. This is a quote from the IPCC ARG WG1: "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans.

Also 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 Arctic ice free in 2014. 2012 snow will be gone by 2020. 2013 Methane catastrophe in 2 years because of ice free Arctic. 2018 zero chance of permanent ice in Arctic by 2022.

  1476. @karlwheatley1244  The Arctic minimum summer sea ice trend is zero for the past 17 years. It was almost as high as 1995 the past few years. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance.

  1491. @zakariyaabdullahi5669  A more civilised society would channel, conserve and utilise the increased rainfall. Besides which there is no evidence that Human activity is affecting drought or rainfall. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out of 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Antarctic Sea Ice, Tropical Cyclones. Quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" s11.5.4, p1569. So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" s11.6.4.5, p1579. So no real evidence we changed the weather to cause periods of dryness.

  1495.  @AA-vi1cc  You are so right! But if you took away El Niño, a record increase in Total Solar Irradiance, and the Tonga eruption (all natural events) there would be nothing to see. The Tonga eruption injected 142 megatonnes of water vapour into the stratosphere, increasing its water content by 15%. Water vapour is a far more powerful greenhouse gas than CO2. Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP. There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

  1496.  @AA-vi1cc  Interesting point about Tonga. I found the paper. I have hunch there's more to this, but a hunch isn't very scientific on my part. Total solar irradiance: satellite data from 1979 onwards shows June 2023 at an all time high in over 40 years of measurements (ncei.noaa). There were lows below 1361 W/m² in 2019 to current highs over 1362 W/m² in June (using a lowess curve, which also shows the fastest rate of increase during the period of satellite measurements). So we are looking at a change of around 1½ Watts over the course of 5 years (the maximum difference is 2.1W/m²). That may not sound much but it exceeds the increase in the Earth's Energy Imbalance (0.9 W/m², 2018 - 1.97 W/m², 2023) (NASA CERES EBAF TOA). Overall the current increase in solar irradiance should give a direct global heating effect of +0.1°C, with an indirect effect of +0.2°C (after Schmutz, 2021). This increase in solar irradiance is related to an earlier than expected increase in sunspot activity, which has not yet reached its zenith, and that may not happen for several years (Royal Observatory Belgium), so further heating from this cause can be expected. So increase in TSI 2019- 2023 = 2.1W/m2. Increase in EEI for the same period ≈ 1W/m². Maybe I'm being dense (and no doubt you'll be your usual delightful self and concur), but doesn't that mean that without the increase in TSI, the EEI would be in negative territory?

  1498. The mirage of a climate crisis has hardened into a delusion. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1499. If you hadn't have told me, i wouldn't have noticed. There is absolutely no evidence that we are in a climate crisis. Quite the contrary. For example, there has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.

  1502. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 20 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. Imagine the damage done from all that resource extraction! And for what? Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1503. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  1505. Since 1900 the global temperature has increased by 1.3°C. In that time humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance.

  1509. The North Atlantic current has doubled its speed over the course of a quarter of century (Oziel et al, 2021). This is based on actual satellite observations. The idea the AMOC is going to shut down is based on modelling. There is minimal real world evidence to support these outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really? Sea surface temperatures (SST) were trending downwards 2000-2018 (HadSST 4), and from 1950-1980, and from 1880-1910. The oceans warmed at a faster rate 1910-1940 than 1980-2010. Remember CO2 has been accumulating in the atmosphere at an accelerating rate all the time, so there is little correlation between the two. The ocean has warmed rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2. And Life just carried on.

  1510. @liestricks  The problem for doomsters is Antarctica and the Southern Hemisphere are getting colder. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4.

  1512. Lies and propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires.

  1518. @darrenb3830  Read this again and take as long as you like: “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" Those last two sentences are my favourite. Gone on, read them again. Enjoy.

  1527. Mostly dangerous drivel. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis. This video is anti-humanist.

  1528. Don't worry, there's nothing to be concerned about. There is no objective observational evidence that we are living in a global climate crisis. The IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

  1529. @catalinamaria9169  You appear to be using anecdotal evidence to support your desires. I have an anecdote. A friend of mine has farmed all his life in Carmarthenshire, UK. I discussed climate change with him recently. He had spoken with the old men in the village and considered the changes in his own lifetime. The only thing he could barely discern was that the grass started growing again a little earlier in the spring by a few days on average. Maybe a week. Apart from that the weather was as changeable as it ever was. Upon reflection he was satisfied with that. More grass meant healthier cattle. That's the problem with anecdotal evidence, it's very subjective, so it's of little value in isolation for a big issue like global climate change.

  1530. The oil companies didn't know what was going to happen in the 1980s Nobody did, and frankly nobody does. They had done some scientific research and had constructed some models, which they correctly treated with caution. As everyone should do, as all the subsequent models have been shown not to work, and vary enormously in their output. The problem is you believe these climate models to be Truth Machines. They are not. There is no global climate crisis.

  1534. ​@HealingLifeKwikly It's always the way: if you can't confront the data, say it's cherry picked. There's at least a dozen data sources in my comment, with at least dozen starting points. Cherry picking. Yawn. Can't you think of something else? And the Dustbowl hypothesis. Ludicrous. How do farming practices on 0.1% of the Earth’s surface (Midwest under cultivation) cause extreme warming over 30% of the Earth’s surface (Arctic north of 70°)? Really! Describing the trend in sea ice since the early 1950s is not cherry picking. Examining the entirety of HadCRUT4 Arctic to make a comparison of temperature anomalies and trends is not cherry picking. Using KNMI data from 1851 onwards for Greenland is not cherry picking. If you think recent cooling in Greenland and Canada is cherry picking, let's look at somewhere else: Svalbard. Looking at the European Climate Assessment & Dataset for Longyearbyen, Svalbard, the mean of daily mean temperature graph (1958-2020) shows 1958 around -4°C. The temperature then declined rapidly and stayed lower around -6° or -7°C until the mid 1980's (Remember CO2 was rising all the time). By 2015 it rose to around -2.5°C and there it levelled off for the remaining 5 years of the record. So an overall change of +1.5°C in a little over 60 years. If this is the fastest warming on Earth we have nothing to worry about. But it does show how variable climate can be, and the temperature changes have no relationship to the concentration of CO2 in the atmosphere. The Norwegian Meteorological Institute (MET Norway) has data for Barentsburg on Svalbard. The data ranges from 1912 to 1990. This data shows an extremely rapid warming in the 1910s, 1920s and into the 30s. There was around 8°C of warming in 20 years. That's far, far greater than the illusory warming being proselytised for the past twenty years. The pattern of warming in this MET Norway data is uncorrelated to the changing concentration of CO2 in the atmosphere. "Early 20th century warming in the Arctic: A review" Takashi Yamanouchi, 2011. Check out figure 7 and figure 10. No relationship to CO2. Norwegian Meteorological Office (Seklima) shows something rather interesting for Svalbard's climate. Looking at say 1950 to the present shows no trend in the maximum temperatures. The minima dropped quite considerably from the later 50s. The 60s and 70s had an intensely cold trend of minima. It then warmed in the 80s/90s and from 2005 levelled off. So overall the swings in temperature on Svalbard during the year have become less extreme. Very roughly, it hasn't got hotter, but the winters, which got very much colder, became less cold, now they have stopped getting less cold since about 2005. Svalbard's climate became milder, less extreme than compared to the 60s and 70s, but not hotter. But statistically you can say that each year got hotter, eventhough it's just that fewer low temperatures are recorded, not more higher temperatures. That process of amelioration has stopped. These changes are uncorrelated to the level of CO2 in the atmosphere. So there is no polar amplification. Temperatures have not risen at an unprecedented rate. The big problem for the doomists is peak interglacial warmth is not now but around 8,000 years ago. Proxies show a downward trend to the present day but with an interruption for the Medieval Warm Period (that doomists aren't allowed to believe in) followed by a decent into the The Little Ice Age (which doomists think also didn't exist), and a very slight recovery to the present day still below MWP though. Now I know that the response is to say about the supposed rapid warming over the last century but that's not a fair comparison. That's instrumental - which is itself unreliable (using annual instrumental measurements) - compared with proxy data  whose the resolution is 200 years. If we smooth out the current data over the last two centuries you'd be lucky to see ½ degree per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century).   I notice you didn't have anything to add to your Dustbowl farce. Nevermind, it was funny while it lasted.

The pattern of warming in this MET Norway data is uncorrelated to the changing concentration of CO2 in the atmosphere. "Early 20th century warming in the Arctic: A review" Takashi Yamanouchi, 2011. Check out figure 7 and figure 10. No relationship to CO2. Norwegian Meteorological Office (Seklima) shows something rather interesting for Svalbard's climate. Looking at say 1950 to the present shows no trend in the maximum temperatures. The minima dropped quite considerably from the later 50s. The 60s and 70s had an intensely cold trend of minima. It then warmed in the 80s/90s and from 2005 levelled off. So overall the swings in temperature on Svalbard during the year have become less extreme. Very roughly, it hasn't got hotter, but the winters, which got very much colder, became less cold, now they have stopped getting less cold since about 2005. Svalbard's climate became milder, less extreme than compared to the 60s and 70s, but not hotter. But statistically you can say that each year got hotter, eventhough it's just that fewer low temperatures are recorded, not more higher temperatures. That process of amelioration has stopped. These changes are uncorrelated to the level of CO2 in the atmosphere. So there is no polar amplification. Temperatures have not risen at an unprecedented rate. The big problem for the doomists is peak interglacial warmth is not now but around 8,000 years ago. Proxies show a downward trend to the present day but with an interruption for the Medieval Warm Period (that doomists aren't allowed to believe in) followed by a decent into the The Little Ice Age (which doomists think also didn't exist), and a very slight recovery to the present day still below MWP though. Now I know that the response is to say about the supposed rapid warming over the last century but that's not a fair comparison. That's instrumental - which is itself unreliable (using annual instrumental measurements) - compared with proxy data whose the resolution is 200 years. If we smooth out the current data over the last two centuries you'd be lucky to see ½ degree per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century). I notice you didn't have anything to add to your Dustbowl farce. Nevermind, it was funny while it lasted.

  1541. @christophorfaust2457  If those little girls and their families get richer, and that is what is going to happen, they won't have to haul water. They will, of course, just turn on a tap. And they won't have to chop down trees for firewood, they will just switch on the heating. If they are farmers, modern agricultural methods will allow them to produce more food from less land. They will have less of an impact on the environment, not more. Richer societies divert more resources to the preservation of the environment. It is poverty that degrades the local environment. The little girls who now don't have to haul water, will go to school, and when they come home, they will be able to do their homework thanks to electric lighting. Their higher levels of education will lead to reduced inequality and a lowered birth rate. What's your alternative? Vegan Marxism? 'Big Mother is watching you.' That will not solve your socioeconomic inequality. That communist experiment has been tried repeatedly and caused disaster and misery every time.

  1545. In the last two years Antarctica has added massive amounts of ice. Antarctic ice sheet (1992-2020) annual loss was 90Gt/yr. It's total mass is 24,380,000 Gt (24380000000000000 tons), so it loses less than 0.0004% of its mass annually, which I think you could reasonably round down to zero. It contributed 0.36mm to sea-level rise per year (that's essentially nothing as well). At that rate it will take well over ¼ million years to melt, but we are due for two more glacial periods in that time. That ice is here to stay. There's a bit of a problem with the accelerating ice loss in Antarctica idea. It's not accelerating. If you want to dig down to the actual data, that is. Just so we're clear, I'm referring to the paper entitled "Mass balance of the Greenland and Antarctic ice sheets from 1992 to 2020" by Otosaka et al, 2023. Can I direct you to table 2, and the text below it? If we include the APIS in "continental" (although I wouldn't) there's no pattern with a slight loss overall - neglible. EAIS, by far the larger of the continent's ice caps, both by surface and volume, hasn't lost mass. It has gained mass, but again it's neglible. So that leaves us with WAIS. It's only WAIS that's driving the mass loss from Antarctica, and you can see that from the Figure 4 graph. Figure 4 and Table 2 show there is a step up in mass loss around 2007. You might want to call that an acceleration. However there's a deceleration from 2017 or at least a noticeable reduction in the rate of annual ice mass loss for the period 2017-2020 when compared to 2012-2016. So accelerating then decelerating. The Antarctic Ice sheet is massive and it's never going to melt on the timescale of human civilisation. Then of course since 2000 the Antarctic Ice Sheet cumulative mass balance has either been steady according to NASA GRACE or increasing according to Velicogna et al. The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset.  Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) In reality, "there have been statistically significant positive trends in total Antarctic sea ice extent since 1979." (Fogt et al, 2022. Published in Nature) "since 1979 is the only time all four seasons demonstrate significant increases in total Antarctic sea ice in the context of the twentieth century". A study of Antarctic ice shelves from 1980 to 2021 (Banwell et al, 2023) showed meltwater volume dropped with "decreasing trend in both annual melt days and meltwater production volume over the 41 years.” "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.

  1549. It was b*ll*cks then, and it's b*ll*cks now. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! And for what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1550. @eeeaten  Then I'll just have to go along with the data that scientists have collected. And remember this is global data. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably, which has retreated northwards dramatically since the 1980s and the Earth has greened by 15% or more in a human lifetime (NASA) due to the fertilising effect of that nasty pollutant CO2. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  1551. @eeeaten  The Petm only resulted in a noticeable extinction of benthic foraminifera. There was a more general flourishing of life at that point, especially terrestrial. So if you're right we've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition. This seems to have been connected with cooling, not warming. Oh dear. I noticed you repeatedly used "expect". Why such Great Expectations? The truth is the world is a far better place to live in than our grandparents experienced.
    1
  1552. @eeeaten  Apart from the migration of ecosystems polewards and the foraminifera I mentioned I am unaware of a mass extinction event at the petm that you referred to. I would appreciate some referenced material to confirm your point. Otherwise I think we should assume it did not occur. However the E-O transition did and was connected to cooling. This vague 'period of imbalance' that you refer to and what you 'expect' to happen is countered by facts. The global climate facts I have already referred to, and the exposure of the unscientific way in which IPCC models failed to predict what has, and is happening. These models, I presume are where you get your expectations from. Please be aware that the IPCC's (Scenario A) modelled predictions are junk. Back in 1990 they predicted a warming of 0.30-0.34°C per decade. Of course we've only had 0.13°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it! But there is still no crisis just an unexciting set of observations. The attribution of all warming to human activity by the IPCC is junk science as well. Take AR5: that says all observed warming (0.66°C) since 1950 is due solely to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 is particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative!!! So many scientists/politicians may have reached a consensus, but the science on which that has been built shows no such agreement. That's the facts, not ignorance. And since when did an accumulation of factual information become wilful ignorance?

  1553. These people don't know what they are talking about or they are lying. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. To the start of August the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) was at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since the thirties. The climate crisis was 90 years ago. You missed it.

  1555. @Nicholas Snow  I may have to disagree with your statement. It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020, 2°C above present), and Minoan Warm Periods (Lécuyer, 2018, 4°C above present). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer), far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable. Maybe it was those pesky Neanderthals driving around in their SUVs. That one's been all over the news but if you want a citation I think it was in the 7th December 2022 issue of Nature. The original research was done by some Danish chappy. If you want some really rapid warming look at the CET (Central England Temperature) Instrumental Record between 1690 and 1730 (3°C increase). That might not be reliable enough for you though. Why not try the Dansgaard–Oeschger events? The Dansgaard–Oeschger events were global (Dima et al, 2018).About 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8 °C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. Some researchers believe the Medieval Warm Period was one of these, but I'm not convinced. However, I can provide upwards of 100 citations of science papers that together show the Medieval Warm Period was qualitatively and quantitatively warmer than the current warming, and that it was global in nature, focused around the year 1000. The current warming began around 1700 prior to any large scale combustion of fossil fuels. Also the warming has been small (1°C) and appears to have been largely beneficial. It has not been smooth, for example there was a period of cooling during the 50s, 60s and 70s (NOAA). When many scientists believed the next ice age had begun. Current warming is smaller than predicted by nearly all models (0.13°C per decade since 1979, UAH v6) so around ½°C for the past 40 years but no overall warming over the past 8. This will result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°.

  1559. @J4Zonian  The Rahmsdort paper is all proxies and simulations of the AMOC. They wouldn't dare highlight the actual observations. To quote the Chief Scientist at the National Oceanography Centre, Professor Penny Holliday, "There hasn't been a slow down. There hasn't been a slowing of the AMOC." Actual observations using the RAPID-MOCHA array from 2004 to 2023 show, that although there can be a great deal of variability of flow in the ocean from month to month or even day to day, there has been no decline in the Gulf Stream, with flow oscillating around 32Sv (32 million cubic metres per second) throughout the period of observation. Continuous section measurements of the AMOC, available since 2004 at 26°N from the RAPID-MOCHA array, have shown that the AMOC strength decreased from 2004 to 2012, and thereafter, it has strengthened again. No relationship to CO2. MOC spanning the North Atlantic at 27°N derived from RAPID/MOCHA/WBTS, satellite altimeter, and Argo floats for 1994 to 2020 shows no statistically significant decline (-0.06 Sv per decade). Furthermore blended meridional overturning basin-wide circulation (MOC) trend estimates (Sv) based on combinations of satellite altimetry and in situ hydrography data exist for the South Atlantic for 1994 onwards: at 34.5°S (often referred to as SAMBA) is +0.48Sv per decade. This is a significant positive trend, so no decline, no tipping point, no correlation to CO2. (GLOBAL OCEANS G. C. Johnson and R. Lumpkin, Eds., 2021) The OSNAP MOC Timeseries of observations from Canada to Greenland and across to Scotland, although a shorter timescale (from 2014), show no decline in MOC with the flow fluctuating around 17Sv. Why didn't Box, and Mann, and Rahmsdort highlight that data? That actual data. The data from what is actually going on in the ocean. The real life flow in the ocean, rather than the flow inside a computer. I wonder why.

  1560. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1561. No. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating or decelerating. The trend is linear. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  1564. @user-tm8ko7xm7g  Hmmm. "Very long time to warm". That could describe the Arctic now. NOAA's Global Time Series Average Temperature Anomaly monthly data (1995-2004) for the Arctic region shows the peak anomaly occurred in January 2016 (+4.99°C), another El Niño year, and the trend is now downwards (-0.42°C per decade) as of June 2024. HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from that period. No temperature anomalies from 2000-2019 exceeded 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005. JRA55 SAT (2010-2020) shows most of the Canadian Arctic and Greenland cooling with parts of Canada cooling by 3°C and western Greenland cooling by 2.5°C in a decade. KNMI data (Twentieth Century Reanalysis V2c, 1851-2011, 68°N-80°N, 25°W-60°W, so Greenland) shows the most pronounced warming took place in the 1870s, and when comparing temperature anomalies, highest are in the 1930s and comparison of that period with recent temperature anomalies shows no net warming. Enjoy those cherries 🍒.

  1566. ​@J.R.Y. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). A study by Venter et al (2018) found the Sahara desert had shrunk by 8% over the previous three decades. The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Increased CO2 causes this in two ways: it has a direct fertilising effect (the CFE), and it increases drought tolerance by reducing stomata. This greening of the Earth due to CO2 is now "an indisputable fact" (Chen et al, 2024). In fact, 55.15% of those areas greening have been doing so at an accelerated rate since 2001. Since the start of the Industrial Revolution the Earth's primary productivity has increased by more than 30% (Campbell et al, 2017 and Haverd et al, 2020). Zhu, Piao, & Myneni, 2016 calculate that 70% of Earth’s global greening in the modern period is due to CO2 and only about 13% is due to fertilizer and land use changes by humans. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests.

  1570. @petewright4640  There is no "Global" warming. Satellite data from 1979 onwards (ERSSTv3b) shows the Southern Ocean has cooled by upto 0.2°C per decade and Antarctica has also been cooling by an impressive 0.7°C per decade, with the east of the continent cooling substantial and statistically significantly by 2.8°C since 1980 (reanalysed ERA5 satellite dataset). The southeastern US has cooled. There has been little warming in the tropics. Most warming has taken place in the continental landmasses of the Northern Hemisphere, a little north of 60°.

  1580. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. There is also no trend in the frequency of major hurricanes (Cat 3 +) for the same period, although the trend for the last 20 years is downwards. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. Intergovernmental Panel on Climate Change (IPCC) AR6 report, Chapter 11,"Weather and Climate Extreme Events in Changing Climate" concludes that changes in the frequency and intensity of most severe weather events (with corresponding intense rainfall) have not been detected nor can they be attributed to human caused climate change.

  1583. @DesignFIaw  The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out of 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis.

  1585. @DesignFIaw  Quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" s11.5.4, p1569. So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" s11.6.4.5, p1579. So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" s11.7.1.2, p1585. So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" s11.7.2.1, p1592 So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" s11.7.3.2, p1595. "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" s11.7.4, p1598. That's between 60°N and 60°S, so pretty much where everyone lives.

  1586. @DesignFIaw  I provided what you asked for. You just refuse to accept the answer. There are no objective scientific observations that we are currently in a global climate crisis. Floods in a small area of a small country on a single occasion in a season of the year when flooding has occurred before is certainly not evidence of that. You don't have any evidence, or you would provide it.

  1596. @bobbobby3085  The big problem for doomists is peak interglacial warmth is not now but around 8,000 years ago. Proxies show a downward trend to the present day but with an interruption for the Medieval Warm Period (that doomists aren't allowed to believe in) followed by a decent into the The Little Ice Age (which doomists think also didn't exist), and a very slight recovery to the present day still below MWP though. So there is supposed rapid warming over the last century but that's not a fair comparison with previous ages. That's instrumental - which has its own reliability issues due to it poor spatial and temporally collection (until the advent of satellites) - with annual instrumental measurements compared with proxy data with the latter's resolution intervals often at 200 years. If we smooth out the current data over the last two centuries you'd be lucky to see ½ degree per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century). And let's not forget the Dansgaard–Oeschger events. The Dansgaard–Oeschger events were global (Dima et al, 2018). One about 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8°C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. So shall we say a rate of change about 20°C per century? If that happened now people would assume the Rapture was imminent. But life carried on.

The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  1600. @rawazardalan2288  I am uncertain of your location and how a small increase in the concentration of CO2 in the atmosphere results in an increase in cancer rates in just your area. There are, however, lots of positive effects associated with climate change. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. One of the main causes of death in the poorer parts of the world is attributable to air pollution. This is because they have to burn wood and dung over open fires for cooking and heating in their homes. These people need access to gas stoves and electricity to improve their health and life expectancy. They need fossil fuels to make them healthy and wealthy.

  1601. @MariaMartinez-researcher  It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020), 2°C above present, also Wang et al, 2013, showing the change was at least hemispheric, and Minoan Warm Periods (Lécuyer, 2018, 4°C above present, links Mediterranean to Greenland Ice so at least hemispheric). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer - so don't worry about an ice-free Arctic), far to the north of the current treeline. The big problem for you doomists is it shows peak interglacial warmth not now but around 8,000 years ago. It shows a downward trend to the present day but with an interruption for the Medieval Warm Period (that you doomists aren't allowed to believe in) followed by a decent into the The Little Ice Age (which you doomists think also didn't exist), and a very slight recovery to the present day still below MWP though. Now I know what you're going to say about the supposed rapid warming over the last century but that's not a fair comparison. That's instrumental with annual instrumental measurements compared with proxy data whose the resolution is 200 years. The latter cannot pick out sudden decadal increases (or decreases). If we smooth out the current instrumental data over the last two centuries you'd be lucky to see 0.5°C per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century) in data sets like Osman et al (2021).

  1602. @MariaMartinez-researcher  When it comes to fires Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million and the lowest since 1998 (NIFC). Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there was nothing unusual about 2023 summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  1603. @MariaMartinez-researcher  Finally, the oil companies didn't know what was going to happen in the 1970's. Nobody did, and frankly nobody does. They had done some scientific research and had constructed some models, which they correctly treated with caution. As everyone should do, as all the subsequent models have been shown not to work, and vary enormously in their output. The problem is you believe these climate models to be Truth Machines. They are not.

  1607. @antred11  You missed the differences between the two posts. Both are correct, but perhaps a little too subtle for you. What I'm doing is clearly referencing a major report by a clearly biased alarmist organisation, and I am showing that even the scientists working for them cannot demonstrate any man-made effect on nearly all the climate impact drivers. There is no climate emergency. Anybody can research this for themselves, and should. They shouldn't take mine, yours, or anybody else's word for it.

  1613. Why lie? There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017.

  1614. Governments should be more aware of the data. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. There is no climate crisis.

  1615. @gaminghighlights2481  The retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  1620. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve).

  1623.  @HealingLifeKwikly  Okay, okay. Take it easy tiger. Let's consider some counterfactuals. It warmed far more rapidly in the recent past. Between 1690 and 1730 it warmed by approx 3°C (CET data). Why was that? Those pesky Georgians zooming around in their horseless carriages? Maybe not. The recent warming was nowhere near that, and unfortunately for you it's stopped. UAH satellite data shows no overall warming in the past twenty years. The problem is CO2 is not a very good greenhouse gas. We live on a water world, and water vapour is by far the most important greenhouse gas. It largely masks any effect that CO2 might have. CO2 does have marginal effect but its effect is nearly at the point of saturation within the atmosphere. The effect is logarithmic rather than linear. You can look it up for yourself but essentially CO2 has to double to cause approximately 1°C of warming. E.g. 300ppm to 600ppm. For another 1°C you have to go from 600ppm to 1200ppm. Unlikely to happen. CO2 is not the climate change switch you so desperately want. There are also benefits to higher CO2: the Earth is 15% greener than 20 years ago (NASA data). Don't you want a greener world? It is fertiliser. CO2 is the most important gas in the atmosphere for life and it remains in short supply. What about the polar bears? There numbers are increasing. Strange. The Great Barrier Reef. Never been better. The biosphere and humans will flourish in a warmer world. Why do people migrate from New York to Florida, or Norway to the Canaries? Many times more people die of cold than heat every year. Look, the climate will change. It always has and it always will. Become resilient and adapt. You don't need to worship at the altar of anti-humanist environmentalism. At least don't take anybody's word it's the end of the world. Question their motives and do some thorough research for yourself. There. I'm bored now. Goodnight.

  1626.  @HealingLifeKwikly  You cannot be this precise to one hundredths of a degree it's ridiculous. Especially given the paucity of data.

  1628. @TheWaywardJester  So do you think 10,500 known species have become extinct (0.5% of 2.1million)? And do you accept that the rate of extinction is declining?

  1629. @TheWaywardJester  Take bird species: 11,195 have been counted (not estimated). All of these have been assessed by the IUCN. They catalogued 4 bird species became extinct over the course of 28 years between 1988 and 2016. That's 1.4 per decade or an annual extinction rate of 0.001%. That's a known, not an estimate, so I would make a strong claim with that figure. Also the proportion of species assessed as threatened by the IUCN has declined over from 65% in 2000 (11,000 out of 17,000) to 28% in 2024 (46,000 out of 166,000). This changing outcome of their species assessments is only accelerating as time passes.

  1630. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating or decelerating. The trend is linear. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

"Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  1635. @eat_ze_bugs  And neither has the statement in the video made by the climate justice changeling that there is a problem with our food systems when there isn't. The whole thing is a series of assertions unsupported by any observational evidence, or events that are irrelevant to the premise of the video.

  1636. @eat_ze_bugs  So we've got ten years of record food production. For the first time in the history of humanity you are more likely to be overfed than underfed. And climate change is a non-problem. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no climate crisis.

  1637.  @eat_ze_bugs  I understand the report. Notice when it is predicted what will emerge in the future they use RCP8.5 - The most extreme of modelling. Truly laughable. And even then very little emerges. Maybe a little more rain in some places, maybe a little less in others. Still no change in droughts. When it comes to the heat, one of the relevant papers referenced by the IPCC in support - Perkins-Kirkpatrick and Lewis, 2020 - has the number and length of heatwaves increasing globally (1951-2017) as you would expect in a slowly warming world, but there is no trend for average intensity. However, I dug a little deeper. The data that these heatwave assumptions are built upon are largely non-existent or fabricated. There are two data sources used: GHCN and Berkeley Earth. At least with the one data source GHCN it shows there is no reliable data going back to the 1950s across almost the whole of Indonesia, India, Arabia, Africa, plus Central and South America. The other data source Berkeley Earth "observational" dataset - now that's a misrepresentation! - just makes it up. It's supposed to be high resolution (1° lat, 1° long 69x54.6miles grid) and go back to 1850. So I thought, hmm, Somalia, the Ogaden and Arabia are looking a bit toasty and red on the maps. Let's check out the data. I found Berkeley Earth’s data sources. I reviewed WMO, GSOD, and NCAR. For the period reviewed in the paper (1950-2014) in the Horn of Africa there were no meteorological station that cover that period. That's right - zero. In the whole of Arabia there were three, just three. Just like Arabia, the whole thing is built on sand. There will be huge parts of the globe where no measurements will have been taken until the advent of satellite technology in the 70s. Very interestingly, if you look at the charts on Fig. 1 on the paper, the US, especially the eastern half looks distinctly unaffected by any increase in heatwaves. Bit of a blue tinge there, I think you'll agree. It's much more difficult to fudge that one because of the huge number of long-term meteorological stations in the US. There is no climate crisis. There is no objective observational evidence that we are living in a global climate crisis. None.

  1638. @eat_ze_bugs  For the predictions in RCP8.5 to be realised the rate of warming would have to quadruple tomorrow and stay that way for 75 years. Really? There's no empirical evidence to suggest the Earth’s climate is that sensitive to CO2, only models, and they all run too hot. I've come across over 100 peer-reviewed papers that demonstrate the ECS is less than 2°C. Please be aware that the IPCC's (Scenario A) modelled predictions were junk. Back in 1990 the IPCC predicted a warming of 0.30-0.34°C per decade. Of course we've only had about 0.1°C per decade, which is well below the IPCC's lower bound of 0.20°C. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it! But there is still no crisis just an unexciting set of observations. All the climate models run too hot, 100% of them. The attribution of all warming to human activity by the IPCC is junk science as well. Take AR5: that said all observed warming (0.66°C) since 1950 is due solely to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 was particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative!!! The problem is you believe these climate models to be Truth Machines. They are not.

  1639. @eat_ze_bugs  There will be huge parts of the globe where no measurements will have been taken until the advent of satellite technology towards the end of the 70s, even in 1979 there were still large parts of the globe - especially, but not exclusively, the Arctic and the Southern Hemisphere - where no readings were taken at all. During the latter half of the nineteenth century reliable records are only really available from parts of Europe, USA and eastern Australia, with a very small number of reliable stations outside of that. Before 1950 there are essentially no GHCN-Daily stations in South America, India, S. E. Asia, China, Africa, or around the Poles. A thermometer on a ship is sufficient for a historical dataset! And what of calibration and standardisation? You seem like an intelligent individual, so how can people like you (with a straight face) tell average citizens, how the temperature of the entire globe has change from 150 years ago, and do it to a tenth or a hundredth of a degree? With such paucity of data you must know it's impossible.

  1640. @eat_ze_bugs  America has by far the best instrumental data, and it shows overall the South East cooled in the last 120 years. Though that sentence doesn't do justice to the climate's variability. Data from NOAA (2021) shows uneven warming in the twentieth century focused on the South East through until it peaks in the 1930s. Where it should be noted the highest average maxima temperature records remain to this day. Some areas of the West US showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day.

  1642. 60 minutes of propaganda. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating nor decelerating. The trend is linear. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  1643. And I'm one. The retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  1644. @AA-vi1cc  Ah, memories. And you thought it was accelerating when it wasn't. You cannot argue against the facts so you insult me in the hope of downgrading the worth of those facts in order that you do not have to accept the truth. Your cupboard is bare.
    1
  1645. @AA-vi1cc  There's a bit of a problem with the "accelerating continental ice loss in Antarctica" position. It's not accelerating. If you want to dig down to the actual data, that is. Just so we're clear, I'm referring to the paper entitled "Mass balance of the Greenland and Antarctic ice sheets from 1992 to 2020" by Otosaka et al, 2023. Can I direct you to table 2, and the text below it? If we include the APIS in "continental" (although I wouldn't) there's no pattern with a slight loss overall - neglible. EAIS, by far the larger of the continent's ice caps, both by surface and volume, hasn't lost mass. It has gained mass, but again it's neglible. So that leaves us with WAIS. It's only WAIS that's driving the mass loss from Antarctica, and you can see that from the Figure 4 graph. Figure 4 and Table 2 show there is a step up in mass loss around 2007. You might want to call that an acceleration. However there's a deceleration from 2017 or at least a noticeable reduction in the rate of annual ice mass loss for the period 2017-2020 when compared to 2012-2016. So accelerating then decelerating. The Antarctic Ice sheet is massive and it's never going to melt on the timescale of human civilisation. Coming back to what we know though about Antarctica, you doomster cult followers have got a problem with Antarctica, haven't you? It's ice shelves are expanding by mass and volume, plus the continent has cooled very significantly in the past 40 years. But a small part (WAIS) of the ice cap is losing mass. Something is making the WAIS melt it would appear, and it cannot be the increasingly colder climate.

  1648. There is no climate crisis. The Earth was warmer in the recent and distant past. It also warmed faster in the past. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing (Watts et al, 2018) measured by SPI 1901-2017. Deaths from natural disasters are about 0.6% of what they were a century ago. What else? Oh, deserts like the Sahara have shrunk considerably and the Earth has greened by 15% or more in a human lifetime (NASA). On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take nearly 190,000 years to reach 15% extinction i.e. a mass extinction. There is no climate crisis.

  1652. @nuqwestr  The houses in Herculaneum were poorly sited, and destroyed by an act of nature, just like these buildings in LA. The difference is those Romans had no idea about the nature of Vesuvius, whereas modern Californians should be fully aware that wildlife has always been endemic in the state. More precautions should have been taken. There is nothing the Romans could have done. There's plenty the Californians could have done.

  1653. Michael Mann's hockey stick is a confection, a concoction. There is no climate crisis. The Earth was warmer in the recent and distant past. It also warmed faster in the past. The extra CO2 in the atmosphere has been beneficial leading to a 15% greener Earth in 20 years (NASA data).

  1654.  @eattherich1793  Greening is necessarily a good thing. As well as feeding plants directly. It makes plants more drought tolerant by reducing the number of stomata on the leaves. So the greening is especially pronounced in those marginal areas such as the Sahel where human population are now at less risk of starvation from bad harvests.

  1662.  @eattherich1793  And Michael Mann is a paragon of virtue. And what you're saying in the general warming trend shown in the UAH data is actually a cooling trend. Cooling is warming and warming is cooling. Got it thanks. Sweet dreams.

  1664. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%! Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Lives will be saved. Warming is good not bad.

  1665. There is no climate crisis.

  1667. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1672. @Aanthanur  so IPCC didn't mean it when they said “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" s11.5.4, p1569. "There is low confidence that human influence has affected trends in meteorological droughts in most regions" s11.6.4.5, p1579. "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" s11.7.1.2, p1585. "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" s11.7.2.1, p1592 "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" s11.7.3.2, p1595. "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" s11.7.4, p1598.

  1673.  grindupBaker  Your ad hominem remarks regarding my character are merely a diversion. It doesn't matter what I am. You are attempting to divert yourself and others from the facts, the objective reality, probably because it does not sit well with your own belief system regarding the world. You cannot argue against the facts so you insult me in the hope of downgrading the worth of those facts in order that you do not have to accept the truth, and damage your own internal narrative as that would be too uncomfortable for you.

  1674. Scientists actually say...There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. The IPCC reports in AR6, chapter 11, "The total global frequency of TC [tropical cyclone] formation will decrease or remain unchanged with increasing global warming (medium confidence)." Not that I really care about what the IPCC says. Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. What else? Oh, deserts like the Sahara have shrunk considerably since the 1980's and the Earth has greened by 15% or more in a human lifetime (NASA). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years. It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. There is no climate crisis.

  1677. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1678. As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’

  1683. The Lancet's Countdown on Health and Climate Change (2019) shows Climate-related deaths are a small proportion of all-cause fatalities (1990–2017). That is based on data per IHME (2019), and between 1990 and 2017, the cumulative age-standardized death rate (ASDRs) from climate-sensitive diseases and events (CSDEs) dropped from 8.1% of the all-cause ASDR to 5.5%, while the age-standardized burden of disease, measured by disability-adjusted life years lost (DALYs) declined from 12.0% to 8.0% of all-cause age-standardized DALYs. Thus, the burdens of death and disease from CSDEs are small, and getting smaller. However, the declines in death and disease rates from CSDEs since 1990 are only a small proportion of longer-term declines across the globe. In the USA, one of the few places with good long-term data, death rates from dysentery, typhoid, paratyphoid, other gastrointestinal diseases, and malaria – all water-related diseases and therefore, almost by definition, climate-sensitive declined 99–100% between 1900 and 1970. We are solving our problems with CSDEs faster than we are solving our other health problems. Indur M. Goklany

  1685. @RP S  The has been warming at an averaged rate of 0.13°C per decade (UAH v6) since 1979 not 0.2°C. It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020, 2°C above present), and Minoan Warm Periods (Lécuyer, 2018, 4°C above present). It was certainly warmer during the Holocene Climatic Optimum, so during our current interglacial. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during that time, with trees growing on the shores of the ocean (which would have been ice free in the summer), far to the north of the current treeline. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable. Maybe it was those pesky Neanderthals driving around in their SUVs. That one's been all over the news but if you want a citation I think it was in the 7th December 2022 issue of Nature. The original research was done by some Danish chappy. If you want some really rapid warming look at the CET (Central England Temperature) Instrumental Record between 1690 and 1730 (3°C increase). That might not be reliable enough for you though. Why not try the Dansgaard–Oeschger events? The Dansgaard–Oeschger events were global (Dima et al, 2018).About 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8 °C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. Some researchers believe the Medieval Warm Period was one of these, but I'm not convinced. However, I can provide upwards of 100 citations of science papers that together show the Medieval Warm Period was qualitatively and quantitatively warmer than the current warming, and that it was global in nature, focused around the year 1000. The current warming began around 1700 prior to any large scale combustion of fossil fuels. Also the warming has been small (1°C) and appears to have been largely beneficial. It has not been smooth, for example there was a period of cooling during the 50s, 60s and 70s (NOAA). When many scientists believed the next ice age had begun. Current warming is smaller than predicted by nearly all models (as I said 0.13°C per decade since 1979, UAH v6). This could result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°.

  1686. @RP S  You can't just say "Wrong" and what I write becomes wrong and what you write becomes fact. You may have come across contrary research to mine, but that doesn't negate it. As we have reached an impasse, the most generous position we could come to is the jury is out on the point of comparison between the temperatures for the Current and Medieval Periods. However, the Roman, Minoan and the Holocene Climatic Optimum were all warmer than present and global in nature. Also the O-D event that I mentioned that led to the Holocene was a far more rapid warming event than today's. I would say that I have not cherry picked from the UAH satellite dataset. It shows a linear warming trend (if taken in its entirety from Jan 1979 to Jan 2023) of 0.13°C per decade. Another enlightening dataset I have come across is the US Climate Reference Network (USCRN) which is run by NOAA. Interestingly, since being set up in Jan 2005 to the present (Dec 2022), it shows no warming. As a matter of fact, it shows cooling of -0.61°C! Of course it hasn't been up and running for an extended period, but a huge amount of warming would be required over the next decade or so to show a positive trend.

  1687. Short answer: it doesn't! Notice how no actual food production values were used in this video. That would destroy the doomer narrative. Between 1961 and 2021 cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UN FAO). All this happened in a warming world, and previous El Niños had absolutely no effect on production. Just have a think...for yourself.

  1689. @WeToddEd-r3g  The "Historical" column is based on objective observations, i.e. things that people have measured. They've happened or are happening (or in this case mostly not happening). The "Emerging" columns are based on models. These are things that haven't happened, and in this case, are so unlikely to occur that they can be disregarded. Let me explain why. The climate scenarios used have already diverged from reality quite significantly, and by 2050 the projected annual CO2 emissions from these scenarios will be double, or more than double the actual emissions.

  1690. @Aaronwhatnow  Who decides it is the wrong type of coral? The people who don't like the coral growing. It damages the climate crisis narrative. The AIMS Long-term Monitoring Programme (LTMP) data for the GBR started in 1985. At the start of the data sequence for the whole GBR cover was 25% in 1986. It reached a low point in 2011 of 12%. In 2022, the LTMP found record high coral cover on the GBR of 34% coral cover on the seabed of the coral reefs monitored. Increases in bleaching events has not prevented rapid and record increases in coral cover. AIMS states "Percent hard coral cover is one standard measure of reef condition recorded by scientists worldwide, it provides a simple and robust measure of reef health" with that in mind, and it being such a robust measure, let's just say it loud and clear: hard coral cover is at record-equalling levels in all three sectors of the GBR.

NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1700. @G  This is not "cherry picking " but examples of eminent scientific research. None of which you have attempted to dismantle. Most of the examples noted were global or at least hemispheric. When the Earth's climate does warm, this warming does not occur evenly. There will be very little change at the tropics. The temperature changes that occur are extra-tropical i.e. towards the poles. This temperature differential is magnified during ice ages (about 40°), is less now (about 20°) and was even less during the Eocene (about 5°). There is plenty of evidence from around the world that large and rapid temperature changes have occurred in the recent past especially the Medieval Warm Period which required no extra radiative forcing from human activity. Please understand the climate system here on Earth is more complicated than we yet know and that CO2 is not THE control knob.
    1
  1701. @G  Unfortunately, NASA (2010) would disagree with the entirety of Science. They believe that two-thirds of man-made warming is due to CO2. The problem with this, the IPCC and others (like your good self) is they rely on models rather than observations to show warming is entirely man-made. When you "look under the hood" (IPCC 2013, p882) you see the result is a compound of 15 models with wildly different outcomes that have to be "scaled" to fit the believed level of warming - that's fudging it so it fits. Most models show very excessive warming, but some show cooling! This gives an exceptionally large variation in the computed man-made warming. Much larger than the believed level of warming (0.66°C 1951-2010), because of that one should not have confidence in the overall values provided. It's bad science.

  1702. @Brian  When it comes to the extent of the previous warming events you mentioned these events were not local in nature. The Minoan Warm Period was identified in the Greenland Ice record as pointed out in the paper I cited, if you'd bothered to read it, so it was at least hemispheric. The Roman Warm Period was not just in Rome (see Wang et, 2012, published in Quaternary International) but has also been identified on the other side of the world. When it comes to the Medieval Warm Period, I can quote you upwards of 100 recent peer reviewed published scientific papers that cover all the Earth's continents and show both qualitatively and quantitatively that the Medieval Warm Period was hotter than the Current Warm Period.

  1704. When it comes to fires Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US in 2023 was 3rd lowest on record. It was under 3 million acres well below the ten year average of 7 million and the lowest since 1998 (NIFC). Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there was nothing unusual about 2023 summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  1705. Britain currently has 39.3 GWh of pumped storage. There are 4 pumped storage stations in Britain. No meaningful storage capacity has been added to the grid since the 1980s, and there is no other large scale energy storage in the country. To cover a cold dark still winter you would need to increase pumped storage capacity by a factor of about 1000 (taking into account pumped storage is about 75% efficient). So we would need to find 4000 suitable locations where a 300 to 400m dam can be built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. Then we would have to build 160 of these every year, year after year, for 25 years. The scale, and the massive cost of storage, by whatever method (pumped storage is one of the cheapest by the way), make it an impossible mission. "Wind droughts" where electrical generation runs at 20% of capacity lasting 100 days or more can be expected once every 50 years. This would see a shortfall of 2TWh at current capacities. 665TWh electricity is projected to come from wind power in 2050 (National Grid). Current wind power 75TWh (2020). 350TWh of Hydrogen storage would exceed by a considerable margin the current annual electrical generation in the UK (~300TWh). It would also be more than 50% of electrical consumption in 2050. Hydrogen storage is also one of the more expensive energy storage strategies at $203/MWh. Pumped storage $131/TWh with gas generated about half of the latter (At 2021 prices researched by Pacific Northwest National Laboratory). Let's look at it another way. The Royal Society recommend the UK should have 100TWh of energy storage (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd.

  1706. Lies and propaganda. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires.

  1707. @tastytoast4576  We are repeatedly told this is a global climate crisis. At the height of northern summer so far this July, of 176 countries in the Northern Hemisphere, only two (China and Albania) have broken their national records, which is a little disappointing considering all the scary reporting. It's more what you would expect from a slowly warming world (~0.1°C per decade UAHv6), which is, of course, what we're living in. There is no objective observational evidence that we are living in a global climate crisis.

  1708. @hosnimubarak8869  The Party line is the number and length of heatwaves has increased globally (1950-2014) as you would expect in a slowly warming world, but there is no trend for average intensity (Perkins-Kirkpatrick and Lewis, 2020, also ref. by IPCC). However, data that these heatwave assumptions are built upon are largely non-existent or fabricated. At least with the one data source GHCN it shows there is no reliable data going back to the 1950s across almost the whole of Indonesia, India, Arabia, Africa, plus Central and South America. The other data source Berkeley Earth "observational" dataset - now that's a misrepresentation! - just makes it up. It's supposed to be high resolution (1° lat, 1° long) and go back to 1850. So I thought, hmm, the Horn of Africa and Arabia are looking a bit toasty and red on the maps. Let's check out the data. I found Berkeley Earth’s data sources. I reviewed WMO, GSOD, and NCAR. For the period reviewed in the paper (1950-2014) in the Horn of Africa there were no meteorological station that cover that period. That's right - zero. In the whole of Arabia there were three, just three. Just like Arabia, the whole thing is built on sand. Very interestingly, if you look at the charts on Fig. 1 on the paper, the US, especially the eastern half looks distinctly unaffected by any increase in heatwaves. Bit of a blue tinge there, I think you'll agree. It's much more difficult to fudge that one because of the huge number of long-term meteorological stations in the US. And why do they start in 1950, and not 1930 or 1900? Hmm.

  1709. There is zero objective evidence that we are in a global climate emergency. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920.

  1710. The lady in the nice hat has nothing to worry about. The Sahel, of which Chad is a part, has been greening since the early 80s as the Sahara retreats northwards. This is due the fertilising effect of extra CO2 in the atmosphere and a slight increase in temperatures from the cold period of the 70s. There is no climate crisis.

  1711. Anomalous/record-breaking cold continues to affect the Antarctic. On Sunday, March 10, 2024, values below -60 °C were measured again in Vostok: -63.1 °C, to be exact. As for Antarctic sea ice, a remarkable – and strangely overlooked – reversal of fortune is taking place. The once cripplingly low extent is now higher (3,165,625 km²) than it was 27 years ago (3,075,000 km²). Just as in 1997, the ice extent today is greater than in 2023, 2022, 2019, 2018, 2017, 2011, 2006, 1993, 1992, 1991 and 1981. As with Antarctic sea ice extent, the Arctic is doing exceptionally well, considering that this is the “hottest year in the last 125,000 years”.The official data shows that Arctic sea ice extent (as of 20th March, 2024) is well above the multidecadal average. It is also well above the 21st century average.

  1714. Stop worrying. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1716. @Hosni Mubarak  When you use data from the World Bank and global insurance, and try to measure the cost to society, you find the cost is minimal and diminishing. Global weather losses as a percentage of Global GDP sank from 0.25% to below 0.20% between 1990 and 2022. Based on data published in the Lancet in 2019, GDP percentage Climate-Related Disaster Losses have declined in all global income categories, with the most noticeable declines in the lower income countries (Watts et al., 2019).

However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

  1720. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad.

  1721. Heat waves have not been increasing in intensity or frequency in the United States, which has by far the best meteorological data both spatially and temporally. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. In 2023 only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. This is shockingly bad reporting by the BBC.

  1722. The ocean has warmed (and cooled) rapidly and repeatedly during the current interglacial with no correlation to CO2 e.g. 10,300-10,200 years before the present (y BP), 9,500y BP, 6,000-5,900y BP, 5,400-5,300y BP, 2,500-2,300y BP, 1,700-1,600y BP (Berner et al., 2008). There is a high frequency (18 events) of SST variability on the order of 1-3°C during a 10-50 year time resolution throughout the Holocene in the North Atlantic with no correlation to CO2.

  1723. Why lie? The Mediterranean Sea was 2°C warmer during the Roman Period and it didn't harm them (Margaritelli et al. 2020). A recent Lancet study showed how many many more people die from cold than heat in Spain. Spain's output of wheat hit a record high in 2021, and has been steadily increasing for decades. If you're worried about Greece, don't. Can I recommend “In Search of Climate Crisis in Greece Using Hydrological Data: 404 Not Found” (Koutsoyiannis et al, 2023)? It shows since records began in the mid-nineteenth century, there is no long term climate variability. Apart from it being slightly wetter 1990-2020 than 1960-1990.

  1730. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  1732. The Arctic minimum summer sea ice trend is zero for the past 17 years. In the past few years it was almost as high as 1995. The probability that this could be due to chance has now dropped to 10% (after Swart et al calculations, 2015). If the hiatus continues until 2027, it will become statistically significant (p<0.05, or less than 5%) and no longer explainable by chance. Using National Snow and Ice Data Centre (NSIDC) information for September minima (million km²): 2007 4.16 2008 4.59 2009 5.12 2010 4.62 2011 4.34 2012 3.39 2013 5.05 2014 5.03 2015 4.43 2016 4.17 2017 4.67 2018 4.66 2019 4.19 2020 3.82 2021 4.77 2022 4.67 2023 4.23 Plot the trend line for this data and it will be flat. ZERO net change in 17 years. The linear trend since 2007 is indistinguishable from zero ( around -0.17% per year ). In the early 1950s the sea ice concentration anomaly was lower than it is at present. The sea ice anomaly then rose during the 50s, 60s and 70s. This was followed by a decline. This is demonstrated in Arctic and Antarctic Research Institute (AARI) data, which is based on historical sea ice charts from several sources (aircraft, ship, and satellite observations). The AARI data shows the sea ice concentration anomaly was lower in 1952 (-5%) than 2005 (-3%). The anomaly increased in the 50s, 60s and 70s. In the 80s, 90s and early 2000s it decreased. Since 2007 the trend has been flat. JAXA (Japanese Aerospace Exploration Agency) satellite data from 2002 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. No other year since has come close. MASIE (Multisensor Analyzed Sea Ice Extent - Northern Hemisphere) shows something similar to JAXA. From 2005 to 2024 Arctic Sea Ice Extent (365 day running average) shows no noticeable trend with values close to 10,000,000km² throughout. Their minimum extent for daily values was in 2012. Again no other year since has come close. It also shows a marked increase in Ice in the Greenland Sea since 2018. Polyakov et al (2003) show "ice extent (1900-2000) in the Kara, Laptev, East Siberian, and Chukchi Seas provide evidence that long-term ice thickness and extent trends are small and generally not statistically significant". Trend -0.5% per decade (±0.7%). Vinje (2001) shows a deceleration in the rate of ice loss from 1864 to 2000. Recent sea ice extent is very high when compared to the last 10,000 years. Also changes in sea ice extent and the speed of those changes were greater in the past (Stein et al, 2017). HadCRUT4 Arctic (70N - 90N) monthly surface air temperature anomalies record (1920-2021) shows the greatest number and magnitude of positive temperature anomalies occurred between 1930-49. All anomalies in excess of 5°C, including +7°C (referenced to 1961-1990) are from this period. No temperature anomalies from 2000-2019 reach 5°C. It shows no decade warmed faster than the 1930s and the current 'warming' finished in 2005.

  1736. They are using lies to get money. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating or decelerating. The trend is linear. Atolls in the Pacific nations of the Marshall Islands and Kiribati, as well as the Maldives archipelago in the Indian Ocean, have risen up to 8 percent in size (Ford and Kench, 2020). 89% of the globe’s islands and 100% of large islands have stable or growing coasts (Duvat, 2019). No island larger than 10ha decreased in size. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

"Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear.

Anyway, I've got some more of those citations you like. Maybe this time you will concede or better still counter my position. Or at the very least respond. So my position as you can see still remains it It was warmer during the Medieval (Elbert, 2013, 2.9°C above present), Roman (Margaritelli, 2020, 2°C above present), and Minoan Warm Periods (Lécuyer, 2018, 4°C above present). I have also discovered there are numerous scientific papers (sort of a hundred) when taken together demonstrate the Medieval Warm Period was warmer than the present and that it was a global phenomenon. I must thank you for that as your request for citations stimulated me to do more thorough research. Cheers, Hos.
    1
  1745. @Hosni Mubarak  The reason I chose the Elbert paper is that it was from Chile in the Southern Hemisphere, so that you wouldn't say it was local. I have failed. And you're probably going to need a sprinkling of citations from all over the world. Even then you will refuse to be convinced.

  1746. @Hosni Mubarak  The Lécuyer paper ties the Mediterranean record in with the Greenland Ice data, so it could be argued it is global or at least hemispheric. And if you want to go global with the Roman Warm Period there's a 2013 paper by Wang et al. that identifies it in South West Florida. Hos, if I can produce a range of citations from a range of continents identifying the Medieval Warm Period as warmer than the present, will you concede that the Earth's climate has been warmer in the recent past?

  1749. @Hosni Mubarak  These papers together are promoting the idea that the climate of the past was spatially and temporally variable but that the warming that the Earth is currently experiencing is consistent and global. This is not the case. The warming in the current modern era has been neither consistent nor rapid both temporally and spatially. The climate of the US in the 20th century is a good example of this. Remember that the land surface of the US is very comparable to that of China. The US has by far the best actual temperature recordings for this modern period (with very little coverage elsewhere outside of Europe). The accuracy of this data is obviously far superior to estimates using proxies from the past. This is not to disregard the use of proxies (after all there weren't any Chinese peasants wandering around in the Middle Ages with a thermometer) but to use caution and allow for the fact that there will be a large error range from them. Hence the variability demonstrated from past climates may be an artefact. Modern data from NOAA (2021) must be considered more reliable. It shows uneven warming focused on the South East through the early part of the 20th century until it peaks in the 1930s. At which point it should be noted the highest average maxima temperature records were set for the modern era. Some areas of the West showed negligible warming. There then followed a general continent-wide cooling into the 1970s. Then the West began to warm, but the South East continued to cool, so that by the end of the century some SE areas were cooler than they had been a century before. This pattern of uneven warming continues up to the present day. All of this demonstrates to my mind that the climate has a strong internal variability both temporally and spatially without the requirement for any external anthropogenic forcing. Globally satellite data also shows how variable the Earth's climate is with changes up or down of 1°C occurring from one year to the next.

  1750. @Hosni Mubarak  You might want to also take a look at the state of the art US Climate Reference Network (run by NOAA). It shows a large degree of variability over shorter timescales but no warming overall since 2005 when they started recording. In fact it shows cooling of about 0.6°C. Of course one needs to take some care with this because of the relatively short period of time. But it is intriguing.
    1
  1751. @Hosni Mubarak  So we can agree the current warming has been variable both temporally and spatially. On large scales and small. Just like previous warmings. I'm not sure aerosols can explain the patterns of temperature change we see in the data. What do you think about slight cooling (0.6°C) in the USCRN data from 2005?
    1
  1752. @Hosni Mubarak  That's fair enough as I indicated in the comment you replied to. Let's say the jury's out. I just would have expected at least some warming in the data by now rather than cooling, especially as there has been an accelerating increase in CO2 in the atmosphere. Another 5, 10, 15 years could be decisive.
    1
  1753. @Hosni Mubarak  Yes, it's super isn't it? Current warming from global satellite data (UAH v6) from 1979 shows warming at a rate of 0.13°C per decade (although there's been no overall warming for the past 8 years). As there's less than 80 years left in this century by 2100 a warming of 1°C will have occurred. Hardly noticeable. Barely an inconvenience.

  1754. @Hosni Mubarak  This just shows how much internal variability there is in the climate. But to get back to it, there's very little warming going on. There is no climate emergency. The Earth was warmer in the past. It also warmed faster in the past. My original statement stands.

  1755.  @hosnimubarak8869  The Dansgaard–Oeschger events. They are global (Dima et al, 2018). They are usually a change of 5°C over a few decades. However, about 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8 °C over 40 years, in three steps of five years.

  1759. @Hosni Mubarak  Oh dear. No, I'm afraid that's not the case. The whole of continental Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. That's brrrrr-illant 🥶! Get it! So much for "Global" warming.

  1760. @Hosni Mubarak  I don't know who that is. I'll have to look him up. I was referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 dataset. Check out table 4. Furthermore, the Antarctic Peninsula has since been shown to be cooling.

  1763.  @hosnimubarak8869  Yes! So nearly the whole of Antarctica is cooling - significantly! 2.8°C for East and 1.6°C for West in 40 years.

  1765. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  1766. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  1769. This is a scare story about things you cannot see. Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 908 known lost species for 2.1 million known species in 500 years (IUCN Red List), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data). Take bird species: 11,195 have been counted (not estimated). All of these have been assessed by the IUCN. They catalogued 4 bird species became extinct over the course of 28 years between 1988 and 2016. That's 1.4 per decade or an annual extinction rate of 0.001%. Also the proportion of species assessed as threatened by the IUCN has declined rapidly over time, from 65% in 2000 (11,000 out of 17,000) to 28% in 2024 (46,000 out of 166,000). This increasingly positive outcome of their species assessments is only accelerating as time passes. Using IUCN data on assessed species- Amphibian species extinct 0.009% per decade. Mammals 0.029% per decade. Reptiles 0.006% per decade. Fish 0.006% per decade. Insects 0.009% per decade. There is no climate crisis.

  1770. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1772. @Richard Blazer  In no way did my comment imply that humans do not have an effect on the environment e.g. chopping down trees. Although global tree cover increased by 7% between 1982 and 2018. And it should also be noted that the Earth has got a lot greener over the last four decades, with over 40% of the Earth's land surface experiencing significant greening. This is largely due to the fertilising effect of the extra CO2 in the atmosphere. Seems like a positive effect to me.

  1778. What can be asserted without evidence can also be dismissed without evidence. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%!

  1780. This video is lying. The Petm (Paeloeocene Thermal Maximum) was not an extinction event. It only resulted in a noticeable extinction of some benthic foraminifera. That was so small an event it doesn't even show up on a marine extinction intensity chart for the Phanerozoic. There was, in fact, a more general flourishing of life at that point, especially terrestrial. So if you're right we've got that to look forward to. The next largest extinction event, since the dinosaurs bit the big one, is the Eocene-Oligocene transition (Grande Coupure). This seems to have been connected with cooling, not warming. Oh dear.

  1781. Another artless piece of propaganda from the BBC. At the height of northern summer in July, of 176 countries in the Northern Hemisphere, only China and Albania have broken their national records, which is a little disappointing considering all the scary reporting. It's more what you would expect from a slowly warming world (~0.1°C per decade UAHv6 and NOAA-STARv5) which is of course what we're living in. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. So far in 2023 (upto 1st August, 2023) the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) is at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since that point. The climate crisis was 90 years ago. We missed it. Then there's the breathless gibberish about Arizona. Phoenix was incorporated in 1881, NOAA only has continuous data from around 1940. So recorded history for Phoenix in this instance is about 80 years (not that long climatically) and the record for 1930s (when heatwaves were much worse) is mostly incomplete. Also Phoenix's population has expanded exponentially in that time from a few tens of thousands to a few million. This has dramatically increased the Urban Heat Island effect resulting in temperatures 10°F (5°C) higher during the day (Scientific American, 2019). This alone explains the record high temperatures. As I'm sure everyone is aware, Phoenix is in the Sonoran desert, which is characterised by long summers and extremely high temperatures. And that's exactly what's happening. There's nothing unusual or unexpected here. Climate change saved 555,103 lives in England and Wales between 2001 and 2020 (ONS, 2022). There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. This applied globally including in the hottest continent, Africa. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones.

Can I recommend you pop over to the website "our world in data" and go to the page "Annual Heat Wave Index in the United States"? Don't worry, it sources its data from NOAA. Now you should see a red spikey thing - that's a graph. You'll enjoy moving the slider along the bottom. Notice that all the tallest spikes are in the 1930s. The very tallest (1936) is 1.34 on the severity index. The most recent readings are around 0.1, so that's a factor of 13. Imagine if you had a heatwave like that now. People like you would be screaming and dropping from apoplexy. How did your ancestors survive without air-con (or global warming!)? Anyway, there's only one, just one, place on this graph you can start and show an increasing trend. That's the 1960s (less than 0.05). And that's why you've chosen it (or it was chosen for you). Another lesson to draw from this is that there is zero positive correlation between the concentration of CO2 in the atmosphere and heatwaves in the US.

  1785.  @swiftlytiltingplanet8481  The famine in the Horn of Africa is endemic not because of climatic factors but because of bad governance and poverty. If you compare these regions to the Gulf States, the climate of the Gulf is similar, although even drier, but the latter have a much higher standard of living due their wealth of fossil fuels and better social organisation. What the Horn of Africa needs is a good dose of reliable energy from fossil fuels to raise their living standards.

  1786. @swiftlytiltingplanet8481  One of the relevant papers referenced by the IPCC in support - Perkins-Kirkpatrick and Lewis, 2020 - has the number and length of heatwaves increasing globally (1951-2017) as you would expect in a slowly warming world, but there is no trend for average intensity. However, I dug a little deeper. The data that these heatwave assumptions are built upon are largely non-existent or fabricated. There are two data sources used: GHCN and Berkeley Earth. At least with the one data source GHCN it shows there is no reliable data going back to the 1950s across almost the whole of Indonesia, India, Arabia, Africa, plus Central and South America. The other data source Berkeley Earth "observational" dataset - now that's a misrepresentation! - just makes it up. It's supposed to be high resolution (1° lat, 1° long 69x54.6miles grid) and go back to 1850. So I thought, hmm, Somalia, the Ogaden and Arabia are looking a bit toasty and red on the maps. Let's check out the data. I found Berkeley Earth’s data sources. I reviewed WMO, GSOD, and NCAR. For the period reviewed in the paper (1950-2014) in the Horn of Africa there were no meteorological station that cover that period. That's right - zero. In the whole of Arabia there were three, just three. Just like Arabia, the whole thing is built on sand. There will be huge parts of the globe where no measurements will have been taken until the advent of satellite technology in the 70s. Very interestingly, if you look at the charts on Fig. 1 on the paper, the US, especially the eastern half looks distinctly unaffected by any increase in heatwaves. Bit of a blue tinge there, I think you'll agree. It's much more difficult to fudge that one because of the huge number of long-term meteorological stations in the US. And why do they start in 1950, and not 1930 or 1900? Hmm.

The trend has been consistently downwards since the thirties. The climate crisis was 90 years ago. You missed it.

  1790. @swiftlytiltingplanet8481  Do you have any data to back up your assertions? As I've already pointed out their is low confidence in a change in drought patterns and its attribution to human activity. For the Horn of Africa, Somalia specifically, World Bank data shows annual rainfall is on an upward trend, and the climatic period 1931-1960 had far lower precipitation in all seasons than the period 1991-2020. Somalia's climate is wetter than in the past. The data is the exact opposite of what you assert.

  1791.  @swiftlytiltingplanet8481  What can be asserted without evidence can also be dismissed without evidence. There has been a 10% decline in natural disasters since 2000 (CRED). Normalised disaster losses have decreased since 1990 and human mortality due to extreme weather has decreased by more than 95% since 1920, so you're 50 times less likely to die from a climate-related disaster in a world that's 1°C warmer than 100 years ago (EM-DAT, CRED/UC). Deaths from drought have declined by 99%!

  1792. @swiftlytiltingplanet8481  When you use data from the World Bank and global insurance, and try to measure the cost to society of climate change, you find the cost is minimal and diminishing. Global weather losses as a percentage of Global GDP sank from 0.25% to below 0.20% between 1990 and 2022. Based on data published in the Lancet in 2019, GDP percentage Climate-Related Disaster Losses have declined in all global income categories, with the most noticeable declines in the lower income countries (Watts et al., 2019). Data. Global data. No climate crisis.

  1793. @swiftlytiltingplanet8481  "As regards disease, the Lancet's Countdown on Health and Climate Change (2019) shows Climate-related deaths are a small proportion of all-cause fatalities (1990–2017). That is based on data per IHME (2019), and between 1990 and 2017, the cumulative age-standardized death rate (ASDRs) from climate-sensitive diseases and events (CSDEs) dropped from 8.1% of the all-cause ASDR to 5.5%, while the age-standardized burden of disease, measured by disability-adjusted life years lost (DALYs) declined from 12.0% to 8.0% of all-cause age-standardized DALYs. Thus, the burdens of death and disease from CSDEs are small, and getting smaller. However, the declines in death and disease rates from CSDEs since 1990 are only a small proportion of longer-term declines across the globe. In the USA, one of the few places with good long-term data, death rates from dysentery, typhoid, paratyphoid, other gastrointestinal diseases, and malaria – all water-related diseases and therefore, almost by definition, climate-sensitive declined 99–100% between 1900 and 1970. We are solving our problems with CSDEs faster than we are solving our other health problems." Indur M. Goklany Couldn't have said it better myself.

  1794. @swiftlytiltingplanet8481  Oh and thinking about UN reports, here's some quotes from the UN's IPCC AR6 WG1: Flooding - “the assessment of observed trends in the magnitude of runoff, streamflow, and flooding remains challenging, due to the spatial heterogeneity of the signal and to multiple drivers” "Confidence about peak flow trends over past decades on a global scale is low." "In summary there is low confidence in the human influence on the changes in high river flows on the global scale. Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence" So in absence of detected trends, there won’t be much ability to attribute to humans. You can't say floods are caused by, driven by, or intensified by climate change. The evidence doesn’t support that. Drought - "There is low confidence that human influence has affected trends in meteorological droughts in most regions" So no real evidence we changed the weather to cause periods of dryness. Tropical Cyclones (TC) - "Identifying past trends in TC remains a challenge...There is low confidence in most reported long-term (multidecadal to centennial) trends in TC frequency - or intensity based metrics" So we can't spot a trend and therefore we can't really attribute that unknown trend to us humans. Storminess - outside the tropics (ETCs) - "There is overall low confidence is recent changes in the total number of ETCs over both hemispheres" "Overall there is low confidence in past-century trends in the number and intensity of the strongest ETCs" So we don't know what's happening with winter storms, so we can't say it's us that changed them. Tornadoes, hail, lightning, thunderstorms, extreme winds - "It is not straightforward to make a synthesizing view of trends in severe connective storms [thunderstorms] in different regions. In particular, observational trends in tornadoes, hail and lightning associated with severe connective storms are not robustly detected" "the observed intensity of extreme winds is becoming less severe in lower to mid latitudes" That's between 60°N and 60°S, so pretty much where everyone lives.

  1795. @swiftlytiltingplanet8481  "Research determined that a 1C increase in temperature translates to 12% in GDP decline." Oh it does, does it? That's strange: Since 1900 the global temperature has increased by 1.3°C (so more than "1C"). Despite that humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  1797. @karlwheatley1244  You seem to be cherry picking referring to individual years, 2022 and 2023 in Canada, 2020 in Colorado. Then accuse me of cherry picking when I quote individual years as part of long-term term data. Long-term data that I quote you see as illegitimate, unscientific, etc without explaining, eventhough my data sources are from reputable and relevant organisations. You shouldn't just ignore those sources. That seems a little unbalanced. You can be better than that. Maybe you should ignore the IPCC as well. The Intergovernmental Panel on Climate Change (IPCC) has examined the issue of 'fire weather' as it pertains to increasing wildfire risk. They conclude that has not even emerged as a signal from climate change and it’s not likely to emerge in the 21st century even using the extreme RCP8.5 scenario (AR6 WG1, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", page 1856, section 12.5.2, table 12.12), so no climate crisis, man-made or othrwise, when it comes to fire weather. Maybe you are right. Maybe there's less wildfire on the planet because of us. Good old humans. "The long term trend is swath[e]s of the Amazon drying out" etc . There is nothing in IPCC data I referenced above about the Amazon drying out now or out to 2100. Also the actual Science does not show the Amazon does not become a carbon source during periods of dryness. 'Amazon rainforest photosynthesis increases in response to atmospheric dryness' (Green et al, 2020). The authors found that, while models show that increases in air dryness greatly diminish photosynthesis rates in certain regions of the Amazon rainforest, the observational data results show the opposite: in certain very wet regions, the forests instead even increase photosynthesis rates in response to drier air.“To our knowledge, this is the first basin-wide study to demonstrate how–contrary to what models are showing–photosynthesis is in fact increasing in some of the very wet regions of the Amazon rainforest during limited water stress,” “This increase is linked to atmospheric dryness in addition to radiation and can be largely explained by changes in the photosynthetic capacity of the canopy. As the trees become stressed, they generate more efficient leaves that can more than compensate for water stress.” Care taken.

  1798. @AA-vi1cc  Not some vague references. Quote some data. Which years had higher coral cover than the past few years and what was that level cover? How much higher was it than now? How has it changed over time? Come back when you've got something quantitative.

  1799.  @AA-vi1cc  Which particular years had higher coverage than the past few years? What were the values for that coverage? How much greater than present? How has coverage changed over time? Quote some data. It would interest me.

  1800. @AA-vi1cc  You don't need to "spell it out". Just quote data. Which years had higher coral cover than the last few? What was the cover value? How did it compare to more recent times? What's the trend? Then try and relate it to the concentration of CO2.

  1806.  @AA-vi1cc  You've got no data to support your assertions.

  1807.  @AA-vi1cc  The AIMS data shows GBR coral cover is the highest it's ever been in the last 3 years.
    1
  1808. @AA-vi1cc  The AIMS Long-term Monitoring Programme (LTMP) data for the GBR started in 1985. At the start of the data sequence cover is 25% in 1986. In 2022, the LTMP found record high coral cover on the GBR of 34% coral cover on the seabed of the coral reefs monitored. The 1986 data is the high point of the 80s and 90s.
    1
  1809.  @AA-vi1cc  No. The data is for the GBR as a whole.

  1810.  @AA-vi1cc  None of this has anything to do with an illusory man-made climate crisis. Corals like it warm. They can't live in cold. Fool.

  1812.  @AA-vi1cc  Because you wouldn't quote the data, in fact you daren't quote the data, I quoted it for you. Coral is doing fine. It survived the KT extinction event and the PETM. You're a fool. Go back to bed.

  1815.  @AA-vi1cc  I am fully aware of the three sections and the data for each section. It remains as stated by AIMS and reiterated by me that coral cover is at record levels on GBR. This you incorrectly denied.
    1
  1816.  @AA-vi1cc  The points I made in my original comment still stand. AIMS shows record coral cover on GBR. GCRMN shows variable cover for different reef systems. This cover is unrelated to CO2. Biodiversity including reef biodiversity is highest in the warmest parts of the Earth's oceans.
    1
  1817. @AA-vi1cc  At the start of the data sequence for the whole GBR cover was 25% in 1986. It reached a low point in 2011 of 12%. In 2022, the LTMP found record high coral cover on the GBR of 34% coral cover on the seabed of the coral reefs monitored. You cherry pick data from the Southern reef only because it helps your narrative (but it doesn't really). The Northern region reached a low point in 2016. However, it has since completely recovered, with coral cover now at double the 2016 level, and recording record cover. The Central region has experienced a greater degree of fluctuation, but is also now at record high coral cover. The Southern region (your favourite) is now at record equalling coral cover, three times higher than at its low point in 2011. Every region is at record-equalling high coral cover, once uncertainty estimates are taken into account. If you are going to cherry pick. I'm going to cherry pick inside your bunch of cherries. Take Capricorn Bunkers. This is one of the sections within the Southern Region (one of eleven). In 2022, Capricorn Bunkers had record high coral cover of 59%, around four times the lowest value, seen in 2011, of 16%. This doesn't do it justice though as the data for the reef shows a great degree of variability. This is natural. The reef always recovers strongly. And it's got nothing to do with CO2.

  1818.  @AA-vi1cc  The data remains the same. GBR record coral cover. No evidence of global scale die off of coral. Greatest diversity of coral in warmest waters.

  1819.  @AA-vi1cc  Record GBR coral. No global collapse. Warmest water most diverse coral. Facts.
    1
  1820.  @AA-vi1cc  GBR has 3 years of record coral cover. The greatest marine biodiversity occurs in the warmest waters. Warmth is beneficial. The reef is not under heat threat due to human activity.
    1
  1821.  @AA-vi1cc  No. The coral are more diverse in warmer waters. If the waters along the coast of Australia warm up, the coral will become more diverse and their spatial range will expand southwards.
    1
  1822.  @AA-vi1cc  No. The data regarding what has happened shows, rather than what is guessed at will happen in the future, changes are due to totally natural factors: predation and weather. AIMS has to insert the 'can' and 'threat' statements as it ensures further funding. The facts in the data remain: record coral cover GBR. No collapse in coral cover globally. More diversity in warmer water.
    1
  1823. @AA-vi1cc  Increases in bleaching events has not prevented rapid and record increases in coral cover. Chiming in with AIMS "Percent hard coral cover is one standard measure of reef condition recorded by scientists worldwide, it provides a simple and robust measure of reef health" with that in mind, and it being such a robust measure, let's just say it again: hard coral cover is at record-equalling levels in all three sectors of the GBR. Crown of Thorns Starfish are also a non-problem. Northern: no starfish or no outbreak on all reefs. Central: no starfish or no outbreaks. Southern: out of 30 reefs, 27 had no starfish or no outbreaks. And once more, oh yes, there is record hard coral cover on the Great Barrier Reef. And that is a robust measure of reef health. What a robust reef!
    1
  1824. @AA-vi1cc  You can have feeding scars but that doesn't mean the starfish are definitely there or any issue, so it is classified as no COTS. What I wrote was entirely accurate and as per the report. In the Southern sector: 1 of the 30 reefs was classified as having a Severe Outbreak, 1 reef had an Established Outbreak and 1 reef had a Possible Outbreak. Four reefs classified as No Outbreak (not "varying degrees of severity and feeding" - you naughty little fibber) and the remainder had No COTS. This definitely agrees with what I wrote. Non problem. Only 1 severe outbreak out of 94 surveyed reefs. The Northern and Central sectors definitely recorded record cover in the past few years. The Southern sector is easily record equalling recorded cover when the margins of error are acknowledged. So I'm going to give you a "simple and robust measure of reef health": hard coral cover is at record-equalling levels in all three sectors of the GBR. That is good news.
    1
  1825. @AA-vi1cc  Northern sector "all reefs were classified as either No COTS or No Outbreak" Central sector "There were no Potential, Established or Severe Outbreaks of crown-of-thorns starfish recorded on Central GBR reefs" which means no COTS or No Outbreak (take a look at the map as well). At this point I would like to remind you of a "simple and robust measure of reef health": hard coral cover is at record-equalling levels in all three sectors of the GBR.
    1
  1826. @AA-vi1cc  Only 1 severe outbreaks out of 94 surveyed reefs. Hard coral cover is at record-equalling levels in all three sectors of the GBR. Anybody can look it up for themselves. You're getting boring.
    1
  1827.  @AA-vi1cc  let's see... Despite bleaching, despite starfish, despite the weather, despite the desires, invocations, and lies by climate alarmists, the GBR has its highest coral cover ever recorded. Maybe they should change its name to the Greatest Barrier Reef.
    1
  1828.  @AA-vi1cc  So let'see... Despite the ravages of starfish, despite the horrors of bleaching, despite the vagaries of the weather, and despite the desires of climate alarmists, the GBR has reached the highest level of hard coral cover ever recorded. We need to rename it the Greatest Barrier Reef!
    1
  1829.  @AA-vi1cc  It's abundantly clear that the simple and robust measure of reef health used by scientists worldwide shows that the reef coral cover is at record levels.
    1
  1830.  @AA-vi1cc  Two key words: simple and (more importantly) robust. GBR has the largest coral cover ever recorded. Greatest Barrier Reef.

  1831.  @AA-vi1cc  It's the Greatest Barrier Reef.

  1837. There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). The Global Land Precipitation Anomaly from AR5 will disappoint with deviations from the average increasing by 0.2% per decade, but if you look at the actual data, it's just very variable over the decades. Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. ) Globally 2000-2019 there was a large decrease in cold-related deaths and a moderate increase in heat-related deaths (Zhao, 2021, Lancet). However, coldwaves are over 9 times more likely to kill than heatwaves, so the overall result is very beneficial. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1838. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. There is evidence cited in AR6 (IPCC) that Australia is experiencing the lowest frequency of tropical cyclones in the last 550 to 1,500 years, so they are talking b0ll0cks.

  1839. Another climate propaganda video. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  1840. Weather events are not climate . The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  1841. Since 1900 the global temperature has increased by 1.3°C. In that time humanity has flourished. Life expectancy has more than doubled from 32 to 73 years.

The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  1844. Everything we do releases carbon dioxide, so the Carbon Cult want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! It's pointless anyway. In just 8 years (prior to 2021) China emitted more CO2 than Britain did since the start of Industrial Revolution that began over 220 years ago! And China plans to vastly increase its coal fired generating capacity. An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1848. @teddansonLA  Of course I have looked at it. I particularly like the blue block denoted by the number 2: extreme heat, already emerged in the historical period. It is based on erroneous science. A paper referenced by the IPCC - Perkins-Kirkpatrick and Lewis, 2020 - has the number and length of heatwaves increasing globally (1951-2017) as you would expect in a slowly warming world, but there is no trend for average intensity. However, I dug a little deeper. The data that these heatwave assumptions are built upon are largely non-existent or fabricated. There are two data sources used: GHCN and Berkeley Earth. At least with the one data source GHCN it shows there is no reliable data going back to the 1950s across almost the whole of Indonesia, India, Arabia, Africa, plus Central and South America. The other data source Berkeley Earth "observational" dataset - now that's a misrepresentation! - just makes it up. It's supposed to be high resolution (1° lat, 1° long 69x54.6miles grid) and go back to 1850. So I thought, hmm, the Horn of Africa and Arabia are looking a bit toasty and red on the maps. Let's check out the data. I found Berkeley Earth’s data sources. I reviewed WMO, GSOD, and NCAR. For the period reviewed in the paper (1950-2014) in the Horn of Africa there were no meteorological station that cover that period. That's right - zero. In the whole of Arabia there were three, just three. Just like Arabia, the whole thing is built on sand. There will be huge parts of the globe where no measurements will have been taken until the advent of satellite technology in the 70s. Very interestingly, if you look at the charts on Fig. 1 on the paper, the US, especially the eastern half looks distinctly unaffected by any increase in heatwaves. Bit of a blue tinge there, I think you'll agree. It's much more difficult to fudge that one because of the huge number of long-term meteorological stations in the US. And why do they start in 1950, and not 1930 or 1900? Hmm.

  1850. @Slevin Channel  This video makes attribution claims to single weather events. 50% for those floods. 30% for that hurricane. Which is ridiculous! And as regards snow, can we make some human attribution to the fact that snow extent has been increasing in the autumn and winter in the Northern Hemisphere since the 1960s, that USCRN has shown a temperature decline of -0.61°C since 2005? No? I didn't think so? Let's just cherry pick some bad weather, and call it a man-made climate crisis.

  1851. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "ever" is not very long! It was much hotter in America in the 1930s, and the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm steadily at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we could even notice it.

  1853. @hmgrraarrpffrzz9763  They are not assumptions but statements of verifiable fact based on objective data. For example, Heatwaves in US were more than 6 times worse than recent events with greater frequency and covering a larger area (Kunkel, 2022, EPA). Look it up for yourself. The same goes for satellite data, try UAH v6. Your argument is from 'authority'. Don't be hoodwinked. Look at the data. Things are far more complicated and nuanced. There is no global climate crisis.

  1854.  @hmgrraarrpffrzz9763  A poll of scientists (meteorologists, physicists, geologists, hydrologists, and climatologists) completed in October 2022 found 59% thought climate change will cause "significant harm", but 39% said either “significant improvement,” “slight improvement,” “no change,” or “slight harm.” That's not a consensus, and that's not "nearly all".

  1856. @boss_albaner  The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution. Increased Hail: not detected, no attribution. increased lightning: not detected, no attribution. Increased Extreme Winds: not detected, no attribution. There is no climate crisis. The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.

  1857. @boss_albaner  Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. Increased CO2 causes this in two ways: it has a direct fertilising effect (the CFE), and it increases drought tolerance by reducing stomata. This greening of the Earth due to CO2 is now "an indisputable fact" (Chen et al, 2024). In fact, 55.15% of those areas greening have been doing so at an accelerated rate since 2001.

  1858. @boss_albaner  Since 1900 the global temperature has increased by 1.3°C. In that time humanity has flourished. Life expectancy has more than doubled from 32 to 73 years. Literacy has quadrupled from 21% to 86%. Humans are seven times more productive ($2,241 to $15,212 GDP per capita, per annum). People are better fed, having ⅓ more calories every day (2,192kcal to 2,928kcal). Global extreme poverty rates have tumbled from 70% to less than 10% (<$1 a day). And death from weather events have collapsed by a factor 50 from 241 million down to 5 million even while the global population has increased by a factor of 5. There is no climate crisis. There is no evidence of a climate crisis. Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points. Barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should be $71,000 with or without tipping points (Dietz et al, 2021). This is the most fortunate time to be alive in the whole of history.

  1859. @boss_albaner  As regards disease, the Lancet's Countdown on Health and Climate Change (2019) shows Climate-related deaths are a small proportion of all-cause fatalities (1990–2017). That is based on data per IHME (2019), and between 1990 and 2017, the cumulative age-standardized death rate (ASDRs) from climate-sensitive diseases and events (CSDEs) dropped from 8.1% of the all-cause ASDR to 5.5%, while the age-standardized burden of disease, measured by disability-adjusted life years lost (DALYs) declined from 12.0% to 8.0% of all-cause age-standardized DALYs. Thus, the burdens of death and disease from CSDEs are small, and getting smaller. However, the declines in death and disease rates from CSDEs since 1990 are only a small proportion of longer-term declines across the globe. In the USA, one of the few places with good long-term data, death rates from dysentery, typhoid, paratyphoid, other gastrointestinal diseases, and malaria – all water-related diseases and therefore, almost by definition, climate-sensitive declined 99–100% between 1900 and 1970. We are solving our problems with CSDEs faster than we are solving our other health problems.

Then they go back to information the scientists gave them and change it. The scientific statements must conform to the political ones, not the other way around.

  1868. @estherzerubb  I trust that you may have found that to be the case. I have seen the reports on the news of fires and floods. I hope that you and yours were not harmed by these natural events. Nevertheless, anecdotal testimony regarding a seasons weather, however unusual, is not representative of how a climate is changing over many decades or centuries, and is not evidence that extra CO2 in the atmosphere is a danger to humanity and the planet.

Their lives of the people of Cahokia would have been circumscribed with superstition and pointless ritual, not an objective knowledge of reality.

  1872. @SpectreNDN  No. Your broadening of definition to dilute the meaning of the word "science" to suit your needs will not do. What the people of Cahokia achieved, although to be enjoyed and marvelled at, did not require science, but was a product of simple trial and error - which is not the same as evidence and experimentation - often with pointless goals, for example the glorification of supernuminous beings. Prior to the Enlightenment numerous civilisations produced many great and beautiful creations, often in excess of that produced by those who inhabited Cahokia and its environs, but without the possibility of any recourse to scientific methodology. This is not to decry what was constructed there. Cahokia is a wonder not because the people there 'had science' but because they did not.

  1874. @SpectreNDN  Nonsense. You tried to essentially redefine what science is so that, to you, it appears to be anything where people did stuff and might have known stuff, which in the case of Cahokia is making mounds, digging ditches, engaging in mass murder especially of girls and young women, while growing and subsisting on corn to the point of pellagra and anaemia. All because "daily life was not believed to be separate from religion" (your words). And you believe - and that's all it is a belief, a faith - that these people were scientists that used the complete scientific methodology. Laughable. Then you insult my intelligence for disagreeing with you, and when I point out your ad hominem somehow that's game over. Ridiculous. The "modern Western frameworks of what scientific methodology is" is Science. What came before it is not Science. The fact that that they didn't have a writing system would have prevented them from developing such a framework as we have today. I'm not "taking advantage" of that. Putting sticks in the ground to tell the time, although clever, is not a "sophisticated knowledge of astronomy". What they had was more like astrology. They would not have understood Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun, and that this caused the seasons experienced in Cahokia. They would have known when the longest and shortest days were because of the length of shadows cast by their sticks. They wouldn't (and couldn't) have understood why these changes took place because they didn't have a scientific way of thinking about them. However their finest "scientists" probably believed they could influence or maintain the consistency of such events by strangling a girl, or beating someone to death. Planting using the largest corn kernels each growing season to produce "high yielding maize varieties" does not mean they had developed an understanding of photosynthesis, plant fertility, or genetics, it was just they wanted to grow more corn so that they didn't get as hungry next year. In fact their understanding of plant growth and fertility probably, once again, to placate the goddess of some overweening witch-doctor, involved murdering some poor peasant girl, or if the harvest was looking really bad, a noble's daughter. Very scientific. That was their system. Very systematic. The mass slaughter of young women. I can hear the old psychopathic priest now "It's been a bad harvest this year, lads. Remember when we executed that virgin and the crops were good the following year, well what we need to do is everyone donate a slave-girl for strangulation, and we'll have a bumper crop next year." And hey-presto, as if by magic (or chance), next year's crop was bountiful. Repetition and Critical Analysis. You probably think cavemen were geneticists because they changed wolves into dogs. Knowledge derived from Scientific methodology is not a fusion of "practical understanding" with "spiritual perspectives". If you think that, which you do, you do not understand what Science is. Spirituality has no place in Science. You misuse the word Science.

  1875. @SpectreNDN  I don't "want" the Mississippian Culture to be inferior to modern Western Culture, it just patently is on so many levels. Codification of Law. People are considered equal before the Law in Western societies. Representative Democracy. One man, one vote with the ability to remove representatives and limit their terms of office. Equality of the Sexes. All previous societies were overtly misogynistic. The freedom of conscience. I don't have to believe in anything if I don't want to. The abolition of slavery. Until the advent of modern Western thought slavery was considered to be normal in all societies. The continuing application of advances made by Science in all areas of technology. For example, the use of Physics and Chemistry in the supply of essentially limitless supplies of energy that frees humans from drudgery and back-breaking labour. The use of Science in the development of modern medicine. Understanding disease, the development of antibiotics and innumerable other treatments and advances in sanitation. The application of Biology to plant and animal husbandry so that for the first time in history you are more likely to be over-fed than under-fed. The list goes on. You obviously don't know how lucky you are. This is the best time to be alive. If you were born in Cahokia around the 12th Century in all likelihood you would be dead of some nasty little disease by the age of 5. If you survived and weren't from a powerful family (so at least 95% of the population) you could look forward to a life of unremitting toil growing and preparing corn. As a woman, you would have had no self-control over the direction of your life. Decisions about you would have been taken by your father, husband or some self-glorified noble or priest. If not an actual slave, you could expect to be treated little better than one. You would have had no recourse to the Law. There was no Law, only the arbitrary exercise of power by a ruthless all male elite. If you made it to puberty the risk existed that you would be made a human sacrifice, probably by strangulation, and put in a mass grave, so that you could serve and gratify some dead chief in his non-existent afterlife. If you did make it to adulthood you would be constantly pregnant and most likely die in childbirth. By 30 you would old and exhausted. A likely cause of death would be a minor infection often from tooth decay. I'm not crazy, but it is self-evident that you lack any real historical insight. It also very sad that you don't understand how very fortunate you are, and any education you have had has only served to obscure this obviously prosperous state.

There was no Law, only the arbitrary exercise of power by a ruthless all male elite. If you made it to puberty the risk existed that you would be made a human sacrifice, probably by strangulation, and put in a mass grave, so that you could serve and gratify some dead chief in his non-existent afterlife. If you did make it to adulthood you would be constantly pregnant and most likely die in childbirth. By 30 you would old and exhausted. A likely cause of death would be a minor infection often from tooth decay. I'm not crazy, but it is self-evident that you lack any real historical insight. It also very sad that you don't understand how very fortunate you are, and any education you have had has only served to obscure this obviously prosperous state.

  1878. @SpectreNDN  I don't "want" the Mississippian Culture to be inferior to modern Western Culture, it just patently is on so many levels. Codification of Law. People are considered equal before the Law in Western societies. Representative Democracy. One man, one vote with the ability to remove representatives and limit their terms of office. Equality of the Sexes. All previous societies were overtly misogynistic. The freedom of conscience. I don't have to believe in anything if I don't want to. The abolition of slavery. Until the advent of modern Western thought slavery was considered to be normal in all societies. The continuing application of advances made by Science in all areas of technology. For example, the use of Physics and Chemistry in the supply of essentially limitless supplies of energy that frees humans from drudgery and back-breaking labour. The use of Science in the development of modern medicine. Understanding disease, the development of antibiotics and innumerable other treatments and advances in sanitation. The application of Biology to plant and animal husbandry so that for the first time in history you are more likely to be over-fed than under-fed. The list goes on. You obviously don't know how lucky you are. This is the best time to be alive. If you were born in Cahokia around the 12th Century in all likelihood you would be dead of some nasty little disease by the age of 5. If you survived and weren't from a powerful family (so at least 95% of the population) you could look forward to a life of unremitting toil growing and preparing corn. As a woman, you would have had no self-control over the direction of your life. Decisions about you would have been taken by your father, husband or some self-glorified noble or priest. If not an actual slave, you could expect to be treated little better than one. You would have had no recourse to the Law. There was no Law, only the arbitrary exercise of power by a ruthless all male elite. If you made it to puberty the risk existed that you would be made a human sacrifice, probably by strangulation, and put in a mass grave, so that you could serve and gratify some dead chief in his non-existent afterlife. If you did make it to adulthood you would be constantly pregnant and most likely die in childbirth. By 30 you would old and exhausted. A likely cause of death would be a minor infection often from tooth decay. Your life would have been "poor, nasty, brutish and short".

  1879. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. Drought appears to be decreasing globally measured by SPI 1901-2017. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1880. 2023 was not the hottest year on large parts of the globe. Asia, Europe, U.S., Oceania, East N. Pacific Region, Hawaiian Region, Arctic, and the Antarctic all enjoyed their highest regional average temperature anomaly in previous years according to data released by NOAA.

  1881. @ThorirEy  Yours is essentially an argument from authority. Arguments from authority are based on the idea that a person should conform to the opinion of a perceived authority or authoritative group. Humans have been shown to feel strong emotional pressure to conform to authorities and majority positions. Is that your case? Science, however, does not work by this type of authorised consensus. Arriving at a consensus is a political or social activity that does not have to approach the truth. Einstein understood this. Interestingly, when over 100 scientists published a booklet (Hundert Autoren gegen Einstein, 1931) against him and his work on relativity, he responded "If I were wrong, it would only take one." Scientific consensus has got it very wrong on many things: smoking, pesticides, and more worryingly eugenics, which was widely accepted in the first half of the twentieth century. I fear this conforming to the consensus is happening again in Science with the mirage of a climate crisis. It is much better to remain sceptical.

  1882. There is nothing to solve. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  1883. The Royal Society recommend the UK should have 100TWh of energy storage (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. A typical pumped storage facility has a 300 to 400m dam built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the less than 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the whole Earth going Net Zero. Good luck with that.

  1884. Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. For the whole of Canada the largest burn acreage was 1989, and there is no trend for the period 1980-2021. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). There is no climate crisis.

  1885. Between 1961 and 2021 global cereal production increased 250% and cereal yield increased over 200%. Land used for cereal hardly increased (Data from World Bank, FAO/UN). This is the only time in human history that you are more likely to be overfed rather than underfed. We should be thankful we were borne into an age of such abundance. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. Global tomato production has set a record each year for the past 10 years. Banana production has doubled in 20 years. All 10 of the largest sugar crops in global history occurred during the past 10 years. All 10 of the 10 largest rice crop years occurred during the past 10 years (UNFAO). 2023 was another record cereal crop.

  1887. More fake predictions by scientists: 1958 the Arctic Ocean will be Ice free in one generation. 1967 there will be global famine. 1970 there will be an ice age in the 21st century. 1970 Oceans will be dead in less than a decade. 1971 50 years away from an ice age. 1972 glacial temperatures within a century. 1974 satellites show ice age coming fast. 1978 no end to cooling trend. 1979 ice at North Pole will melt in one lifetime. 1982 environmental catastrophe by 2000. 1988 Maldives underwater in 30 years. 1989 entire nations underwater by 2000. 2000 snowfall has become a thing of the past. 2004 UK climate will become Siberian. Cities will sink into the ocean. 2006 10 years until a point of no return. 2007 if no action 2012 will be too late. Also 2007 Arctic ice free 2010, or 2015, or 2013, or 5 years take your pick. 2008 the Arctic ice sheet would melt away. Also 2008 North Pole ice free in ... 2008 ... or in 10 years. 2009 Arctic ice free in 2014. 2012 snow will be gone by 2020. 2013 Methane catastrophe in 2 years because of ice free Arctic. 2018 zero chance of permanent ice in Arctic by 2022. Also 2018 humans to go extinct by 2023 from climate change. 2022 End of Snow predicted.

  1888. The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.

  1889. I'm afraid the Doomsday glacier has lost its doom. “No numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023. "Removing TWIS [Thwaite's Ice Shelf] causes a modification in modelled SLR [Sea Level Rise] of 1-2mm SLR equivalent over the first 50 years." That's risibly tiny and described as "negligibly small" by the authors. The removal of the ice shelf "will have almost no discernable effect on the future mass loss of the glacier." Oh dear. There's nothing to see here. You'd better move on to the next scare story. The problem is there is no objective observational evidence that we are living in a global climate crisis.

  1890. The 40°C record was set on the hot tarmac of an RAF airbase as three typhoon jets landed. 😂 "Hot dry summers". Have they looked outside today? What this is saying is don't believe your eyes. The world may be warming now but it was cooling in the 60s and 70s. It was much hotter in the Medieval, Roman and Minoan Warm Periods. And it was certainly hotter during the Holocene Climatic Optimum during the current interglacial. If we do go into a glacial period (and thats a certainty) everyone will be praying for a little warmth as ice several miles thick smothers the country.

  1891. The mirage of a climate crisis has hardened into a delusion. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1892. @ljt3084  "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). It is from a paper entitled "Change in Antarctic Ice Shelf Area from 2009 to 2019". They use MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data to measure the change in ice shelf calving front position and area on 34 ice shelves in Antarctica from 2009 to 2019. Also, as the mass gain (661Gt) was given, you could calculate the volume of the ice gained using the formula: Volume = Mass ÷ Density (assume Density of glacier ice 0.9167 Gt/km³). This would give you (well not you obviously) an Ice Gain Volume ≈721km³. That's how much extra of the lovely white stuff there is around Antarctica. Imagine standing in the centre of this extra ice. It would stretch beyond the horizon in all directions and would be 45 storeys high.

  1893. The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Observations of Earth’s vegetative cover since the year 2000 by NASA’s Terra satellite show a 10% increase in vegetation in the first 20 years of the century. Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature.

  1894. @brothervance1932  Not only are China and India getting greener, but forests are expanding northwards, and deserts are shrinking. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). Also that "potent greenhouse gas" is keeping us fed. A US DoE study (Taylor & Schlenker, 2021) estimated that a 1 ppm increase in CO2 led to an increase of 0.4%, 0.6% and 1% in yield for corn, soybeans and wheat, respectively, and that CO2 increase was the main driver of the 500% yield growth in corn since 1940. There is no objective evidence that we are in a global climate crisis. The Chinese and Indians must be laughing at the West as we destroy our ability to maintain our prosperity and propel ourselves back to pre-industrial poverty.

  1895. Current warming is smaller than predicted by nearly all models (0.13°C per decade since 1979, UAH v6) so around ½°C for the past 40 years but no overall warming over the past 8. This will result in a further 1° of warming by 2100 which can be adapted to, as with the previous 1°. Please be aware that the IPCC's (Scenario A) modelled predictions are junk. Back in 1990 they predicted a warming of 0.30-0.34°C per decade. Of course we've only had 0.13°C per decade, which is well below the IPCC's lower bound of 0.20°. IPCC’s business-as-usual scenario was founded on the assumption that CO2 emissions would increase by 10-20% by 2025. The truth, however, is that global CO2 emissions are not 20% above their 1990 level but 60% above it. But there is still no crisis just an unexciting set of observations.

  1897. NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. That's the same as two stacked penny coins. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.

  1898. @Franck R  Sorry was my cherry-picking data too global for you. I know I quoted the IPCC but it's reports are novels really. This is how it works: The world's leading climate scientists are given that title by cynical politicians. They do not essentially write the final version of the IPCC report. It is reverse engineered. The Summary for Policymakers is thrashed out by a very large group of politicos at the UN. Line by line. Remember, these are not scientists, but government lackies. Then they go back to information the scientists gave them and change it. The scientific statements must conform to the political ones, not the other way around. The IPCC was set up to find man-made global warming and when you look for something you find it, and indeed they have on the face of it, but when you look deeper you find a dearth of real evidence. Take AR5, that says all observed warming (0.66°C) since 1950 is due to combined anthropogenic forcing (Fig. 10.5, IPCC core writing team, page 6). This relies upon modelling, or rather multi-modelling. In fact when you lift the curtain it relies on 15 models (Fig. 10.4, page 882). These models are all over the place. The models' results are not consistent with the assumption that there is a clear connection between GHGs and warming. GISS-EH-2 is particularly 'not well constrained' as the terminology goes. "Scaling factors" then have to be applied so things fit with the HadCRUT dataset. Some of the scaling factors are even negative! Explain why that has to be done!

  1901. @Franck R  This won't have been the first time an idea has taken hold in a society, and that idea grew beyond the bounds of what was real or justified. Take religion and the terrifying or absurd action people will take in the name of their God. Or political ideologies that sound appealing to the masses like communism but the result has been the death of 100 million people or more, and still people believe in it and are willing to try it. This environmental crusade has all the hallmarks of one of these mass manias. A dogma that cannot be questioned (all warming is due to CO2). A priestly caste that are exempt from our trials and tribulations (the politicians in their private jets). A doomsday where the wicked (that's everybody, by the way) will be punished by fire and flood. The possibility of redemption but only through penance (living in cold dark homes, existing in 15 minute cities, and subsisting on gruel and insects), which won't apply to the priestly class. I was brought up a Catholic and the whole pattern of this Climate Crisis nonsense fits to the template beautifully. People are hard wired to be religious so when they stop believing in God they don't believe in nothing they believe in anything. Demagogues will exploit this. A nice way to summarise it is the 3Gs. The reason people who matter do things is for God, Glory, or Greed. Look at the people making a fuss about the Earth getting a bit warmer and they are doing for one of those three or a combination thereof. Stay sceptical.

  1902. @Franck R  The IPCC reports are built on models that don't model reality, as I have pointed out, and for which you have no insight. Their proxy data sets of the CWP don't agree with each other and their temperature 'records' are falsifications that cool the distant past and warm the recent observations. It just won't do. As I have said the warming is just over a tenth of a degree per decade. You get marginal changes in climate patterns: northern Europe gets a bit wetter, southern Europe gets a bit drier. No real pattern in storminess. Sea-level rise of about 1 foot (30cm) by the end of the century. A third of the Netherlands is below sea-level and they're doing fine. The climate was going to change. Just plan for it. It's not the end of the world (which is an idea people have had in every age). Where I live the flowers will come out a little earlier in the spring and that's it. Nobody would notice if you didn't tell them.

  1904. @Franck R  The speed is not an issue. It's warmed by a degree or so since the start of the twentieth century, and everybody adapted by not even noticing. I don't think another or two degree will be unsurviveable. Humans already live in all climates. We will adapt.

  1905. @Franck R  The glaciers in Europe and elsewhere have receded and disappeared (and then advanced again) in the recent past. Often as these glaciers recede the remains of forests are discovered. It was probably the case that there were no glaciers in the Alps during the Holocene Climatic Optimum a few thousand years ago.It was warmer during the Medieval, Roman, and Minoan Warm Periods. It was certainly warmer during the Holocene Climatic Optimum. If you want a citation, try Quaternary Research Volume 53, Issue 3, May 2000, Pages 302-311. This makes the point that it was upto 7°C warmer on the shores of the Arctic during the Holocene Climatic Optimum. The northern coast of Greenland was, during parts of the Pleistocene, warmer by double figures than today. The summer and winter average minimum temperatures of 10 degrees Celsius and 17 degrees C, respectively, were more than 10 degrees C warmer than present day. I think it was a maximum of 19 °C warmer than today. Remarkable. Maybe it was those pesky Neanderthals driving around in their SUVs. This one's been all over the news but if you want a citation I think it was in the 7th December 2022 issue of Nature. The original research was done by some Danish chappy. If you want some really rapid warming look at the CET (Central England Temperature) Record between 1690 and 1730. That won't be reliable enough for you though. Why not try the Dansgaard–Oeschger events.

  1906. @Franck R  I assume, by you describing my points as "cherries," you are accepting their validity and the fact that they support a non-apocalyptic scenario. However, they appear to be insufficient to allay your fears. Very well, as regards the models that predict +4°C warming by the end of the century, which you rely upon for your nightmares, they are running 'too hot' as far as the IPCC are concerned and do not able to mimic past climates. Current warming from global satellite data from 1979 shows linear warming at a rate of 0.13°C per decade. As there's less than 80 years left in this century, warming will have to accelerate dramatically to approx 0.5°C a decade. This is unlikely. At the current rate by 2100, a warming of 1°C will have occurred. Hardly noticeable. Barely an inconvenience.

  1907. @Franck R  Thanks for the numbered points it's a nice idea and helps with the discussion. In response 1-Greenland was not an exception if you read what I have written but part of a warming event that occurred around the Arctic and indeed the Northern Hemisphere. The treeline advanced to the shores of the Arctic, and the ocean was probably ice-free in the summer. This occurred in the current interglacial. That warming and subsequent cooling appears to be related to the Earth's obliquity, not CO2 conc. CO2 rose after the temperature and continued to rise eventhough the climate cooled overall for the past 5000 years. 2-I agree it's going to be a curve or something more sinuous in reality and maybe in this curve we should include the heat of the 1930s and the cooling through to the 70s. Maybe we should include the bit for there being no overall warming for the last 8 years. 3-I accept a 1°C warming has already occurred. Indeed the warming started prior to the Industrial Revolution and any large increase in man-made CO2. What's that all about? That 1°C of warming is also a further indicator not to be alarmed as humanity has adapted to it magnificently. There has never been a more prosperous time to be alive. Another degree of warming will be adapted to. I reiterate it is highly unlikely we will see your required 0.5°C of warming per decade proposed by the models. These models run too hot as evidenced by the IPCC. 4-Thereis nothing unusual about glaciers receding or advancing. Check out Jakobshavn. As regards your worries of other environmental consequences there appears very little of concern.The IPCC has concluded that since 1900 there is “no trend in the frequency of USA landfall events.” This goes for all hurricanes and also for the strongest hurricanes, called major hurricanes, and that there remains “no consensus” on the relative role of human influences on Atlantic hurricane activity. On floods, the IPCC has little to say, conceding that: "Confidence is in general low in attributing changes in the probability or magnitude of flood events to human influence because of a limited number of studies and differences in the results of these studies". And again with droughts the data long term and short term for North America and Europe shows no long term trends. With dangerous feedbacks and thresholds I am going to reject those ideas as the Earth's climate is a multi input thermodynamic system and will conform to Le Chatelier's Principle. To draw this to a conclusion for now as I doubt very much we are going to sway each other, such is human psychology, I'll make you a deal. If in 10 years the Earth has warmed 0.5°C I'll agree with you and it's code red for humanity. On the other hand if it's 0.1°C, you'll take a chill 😎 pill 💊 and stop having nightmares. Life's too short.

  1908. Phoenix was incorporated in 1881, NOAA only has continuous data from around 1940. So recorded history for Phoenix in this instance is about 80 years (not that long climatically) and the record for 1930s (when heatwaves were worse) is mostly incomplete. Also Phoenix's population has expanded exponentially in that time from a few tens of thousands to a few million. This has dramatically increased the Urban Heat Island effect resulting in temperatures 10°F (5°C) higher during the day (Scientific American, 2019). This alone explains the record high temperatures. As I'm sure everyone is aware, Phoenix is in the Sonoran desert, which is characterised by long summers and extremely high temperatures. And that's exactly what's happening. There's nothing unusual or unexpected here. The news story is purposely catatrophising the weather to unnecessarily scare people into changing their way of life. There is no global climate crisis.

  1910. "Insane and dangerous." As regards flooding, the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. In a study on the climate impact on flooding for the USA and Europe, published in the Journal of Hydrology, Volume 552, September 2017, Pages 704-717, the study found: ‘The number of significant trends was about the number expected due to chance alone.’ ‘Changes in the frequency of major floods are dominated by multidecadal variability.’ ‘The Intergovernmental Panel on Climate Change (IPCC) concluded (Hartmann et al., 2013) that globally there is no clear and widespread evidence of changes in flood magnitude or frequency in observed flood records.’ ‘The results of this study, for North America and Europe, provide a firmer foundation and support the conclusion of the IPCC that compelling evidence for increased flooding at a global scale is lacking.’

  1911. @komousch  So global data carefully referenced from internationally recognised organisations like NASA and the UN is cherry-picked, so obviously you can't accept it, and therefore I'm not sure what you would accept. In fairness you don't cherry-pick any data...because you don't reference any data.

  1916. Vandals and barbarians. The mirage of a climate crisis has hardened into a delusion. There is no climate crisis. 10% decline in natural disasters since 2000. Accumulated cyclone energy shows no increasing trend. Global hurricane landfalls shows no trend. Downward global trend for total hurricaine numbers. NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1918. The IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Increased Flooding: not detected, no attribution. Increased Meteorological Drought: not detected, no attribution. Increased Hydrological Drought: not detected, no attribution. Increased Tropical Cyclones: not detected, no attribution. Increased Winter Storms: not detected, no attribution. Increased Thunderstorms: not detected, no attribution.

  1919. No it wasn't record breaking. A few days after this bull, Europe is in a cold wave with a negative temperature anomalies. Frosts are forecast for southern Germany, and people will need to put their heating on in August. Cool, damp and dull for the foreseeable future.

  1920. @notdem notrep  The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset.

  1922. For every million people on earth, annual deaths from climate-related causes (extreme temperature, drought, flood, storms, wildfires) declined 98%--from an average of 247 per year during the 1920s to 2.5 in per year during the 2010s. Data on disaster deaths come from (EM-DAT, CRED / UCLouvain, Brussels,Belgium. )

  1923. Arctic sea ice is not declining. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic, and September 2023 was 4.23. Both of these are higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 17 years. It was almost as high as 1995. There is now a 90% probability that climate scientists predictions about the loss of Arctic sea ice are wrong. If the pause in ice loss continues until 2027, it will no longer be explainable by chance (Swart et al, 2015), or indeed human-induced global warming.

  1924. Another climate propaganda video. The Earth appears to be warming at around 0.13°C/decade (UAHv6, NOAA-STARv5, radiosondes - 28 million weather balloons, and climate reanalyses concur on this). NOAA-STARv5 TLT may even appear to show a reduction in the rate of warming. 1981-2023: +0.129°C/decade, 1981-2001: +0.130°C/decade, 2002-2014: +0.008°C/decade, 2015-2023: -0.060°C/decade. Also there is no "global" warming. The northerly latitudes are warming, but the southerly latitudes are cooling. Maybe it's a Bond Event.

  1925. Good news! There has been a 10% decline in natural disasters since 2000 (CRED). Globally the ACE index (accumulated cyclone energy) 1980-2021 shows no increasing trend. Global Hurricane Landfalls 1970-2021 (updated from Weinkle et al, 2012) shows no trend. Satellite data since 1980 shows a slight downward global trend for total hurricaine numbers with 2021 being a record low year. From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." Multidecadal variability in Atlantic hurricaines is most probably related to the AMO (Vecchi et al, 2021). NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. It makes no difference if you look at the Pacific. Using data from the JMA 1951-2022 we see typhoon activity trending downwards for over 7 decades. What the data from NOAA SPC shows about tornados: EF1-EF5 (1954-2022) no trend; EF3-EF5 (most destructive) (1954-2022) 50% decline. No EF5s in US since 2013 (a record absence). There has been no clear change in annual precipitation over the Earth's landmasses between 1850-2000 (Wijngaarden, 2015). Drought appears to be decreasing globally (Watts et al, 2018) measured by SPI 1901-2017. There are over 5 million excess deaths per annum globally due to abnormal temperatures from the 2000-2019 study led Prof. Guo of Monash University. It found that over 90% of excess deaths were caused by excess COLD rather than excess heat. So, in a world with increasingly mild temperatures, there will be less excess death. Warming is good not bad. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015(Liu & Xue, 2020). The Earth has greened by 15% or more in a human lifetime. "The greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year"(NASA, 2019). Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles) between 1982 and 2016 (Nature, 2018). As well as human intervention, the reasons for this include forests expanding polewards aided by additional CO2 and a slight rise in temperature. The Earth’s natural vegetation productivity actually increased 6% in 18 years (Nemani et al, 2003) with 42% of this increase coming from the Amazon rainforests.

  1927. Super nonsense. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no families or genera have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve).

  1931. Propaganda. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded (AIMS). If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth.

  1933. @karlwheatley1244  The big problem for you doomists is peak interglacial warmth is not now but around 8,000 years ago. Proxies show a downward trend to the present day but with an interruption for the Medieval Warm Period (that doomists aren't allowed to believe in) followed by a decent into the The Little Ice Age (which doomists think also didn't exist), and a very slight recovery to the present day still below MWP though. Now I know what you're going to say about the supposed rapid warming over the last century but that's not a fair comparison. That's instrumental - which is itself unreliable (using annual instrumental measurements) - compared with proxy data whose the resolution is 200 years. If we smooth out the current data over the last two centuries you'd be lucky to see ½ degree per century. Your rapid warming disappears, and a very large number of bicentennial periods over the last 16,500 years warm at a faster rate (than 0.5°C/century). And let's not forget the Dansgaard–Oeschger events. The Dansgaard–Oeschger events were global (Dima et al, 2018). One about 11,500 years ago, averaged annual temperatures on the Greenland ice sheet increased by around 8°C over 40 years, in three steps of five years, but a 5 °C change over 30–40 years is more common for these events. So shall we say a rate of change about 20°C per century. If that happened now you'd be foaming. But life carried on.

  1934. @karlwheatley1244  Apart from the migration of ecosystems polewards and the foraminifera I mentioned I am unaware of a mass extinction event at the petm that you referred to. I would appreciate some referenced material to confirm your point. Otherwise I think we should assume it did not occur. If i can quote from a paper by Aze (2022) "the PETM is not classified as a mass extinction event, as significant levels of extinction are limited to just a handful of taxonomic groups, and overall extinction rates do not increase beyond background levels".

  1935. @karlwheatley1244  Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 908 known lost species for 2.1 million known species in 500 years (IUCN Red List), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs.

It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data).

  1936. The North Atlantic current has doubled its speed over the course of a quarter of century (Oziel et al, 2021). This is based on actual satellite observations. The report in this video refers to a study that bases its predictions on modelling. There is minimal real world evidence to support its outlandish claims. It relies upon climate models. You know, those Magical Truth Machines that keep making false predictions. It claims with 95% certainty that the AMOC with collapse by the end of the century. Come on! Really?

  1943. @AA-vi1cc  NOAA (2022 Arctic Report Card) show winter (March) ice coverage has hardly changed since '79, and that the summer (September) coverage trend had stopped declining since 2007. In September 2022, sea ice reached a minimum extent of 4.87 million square kilometers in the Arctic. This is higher than the extent in 2007, which means the Arctic summer sea ice trend is zero for the past 16 years. It was almost as high as 1995. Summer 2023 is one of the coldest in several decades in the Arctic, and May 2023 was the coldest on record there. The Greenland surface mass balance (SMB) for the past 11 months is a massive but very normal 450 billion tonnes of ice accumulated. 5 out of the last 7 years have seen huge accumulations above the average (1981-2010). The whole of East and West Antarctica is cooling, and has been for 40 years. East Antarctica has cooled by an impressive 0.7°C per decade. Resulting in an overall substantial and statistically significant decline of 2.8°C since 1980. So much for "Global" warming. I am referring to a paper by Zhu et al (2021) that looked at the reanalysed ERA5 satellite dataset. Check out table 4. Furthermore, the Antarctic Peninsula ice has since been shown to be on the increase “The eastern Antarctic Peninsula Ice Sheet has grown in area over the last 20 years, due to changing wind and sea ice patterns.” (University of Cambridge, May, 2022.) "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023).

  1944. @MyKharli  To be clear...It is reasonable from observations to say the Earth is warming, especially in comparison to the Little Ice Age baseline. It does not appear possible to discern how much of the warming is man-made, so it seems unreasonable to affirm that all of the warming is man-made, but adding CO2 to the atmosphere should cause some rise in temperature. However, the warming response should be logarithmic, and empirically, the ECS is around 1.8K. When you look at actual instrumental records, the warming is uneven both spatially and temporally. There is very little warming around the tropics. The Canadian Arctic has warmed. Continental Antarctica has cooled significantly (so no "global" warming). Maybe it's a Bond Event. Within the shallow warming, there are large annual swings greater than the decadal rate of change. It is also debatable how hot the modern era is in comparison to recent and distant warming events, and when making a fair comparison with proxies by using the same resolution (say 200 year) the rate of warming becomes comparable to, or smaller than previous natural events.

  1951. What a waste of time. Methane (CH4) is only 0.00019% (1.9 parts per million) of the atmosphere. Both of its narrow absorption bands occur at wavelengths where H2O is already absorbing substantially. Hence, any radiation that CH4 might absorb has already been absorbed by H2O. With the concentration of water vapour in the atmosphere being between 1,000 and 20,000 times greater than CH4, the effects of CH4 are completely masked by H2O.

Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015.

Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1957. ​@Muddslinger0415 Another artless piece of propaganda from the BBC. As of Sunday 23rd July the Eastern US (except Florida) is in a cold anomaly. I.e. it is colder than average for July. Looking across the Northern Hemisphere the following are also large anomalous cold areas: Northern Europe, Western Russia, Mongolia, Manchuria, and Tibet. This is all weather, not catastrophic man-made climate change. No temperature records have been broken in Europe. Rome was supposed to have broken its, but it wasn't as hot as in 1841. Greece is nowhere near its record of 48°C set way back in 1977. As the report admits it was hotter 50 years ago! There is nothing unusual about the fire season in Europe. Weekly burn area is way below average. Cumulative burn area is average. Weekly Number of fires are below average. Cumulative number of fires are bang in the middle of the normal range. The same is true for Greece, and the fires at present are a tiny fraction of the maximum recorded (EFFIS). There's no trend for wildfires in Greece. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "Overall, the Antarctic ice shelf area has grown by 5305 km² since 2009, with 18 ice shelves retreating and 16 larger shelves growing in area. Our observations show that Antarctic ice shelves gained 661 Gt of ice mass over the past decade." (Andreasen et al, 2023). So Antarctica isn't melting. Then there's the breathless gibberish about Phoenix. Phoenix was incorporated in 1881, NOAA only has continuous data from around 1940. So recorded history for Phoenix in this instance is about 80 years (not that long climatically) and the record for 1930s (when heatwaves were much worse) is mostly incomplete. Also Phoenix's population has expanded exponentially in that time from a few tens of thousands to a few million. This has dramatically increased the Urban Heat Island effect resulting in temperatures 10°F (5°C) higher during the day (Scientific American, 2019). This alone explains the record high temperatures. As I'm sure everyone is aware, Phoenix is in the Sonoran desert, which is characterised by long summers and extremely high temperatures. And that's exactly what's happening. There's nothing unusual or unexpected here. Then tag the floods in: the U.N. IPCC admits having “low confidence” in even the “sign” of any changes—in other words, it is just as likely that climate change is making floods less frequent and less severe. The news story is purposely catatrophising the weather to unnecessarily scare people into changing their way of life. There is no global climate crisis. This is an appalling piece of journalism by the BBC.

  1958. The retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  1960. This climate report is propaganda. The climate attribution studies are based on the relative frequency of daily temperatures in the current climate and in a world without human-caused climate change. Unfortunately, one cannot prove that changes in the climate are man-made, but here it is presented as a fact. To provide proof of this one would need to observe another Earth-like planet to which no extra CO2 had been added. This is obviously impossible. It is untestable. It is unverifiable. It is not a fact. It is not Science.

  1963. That's very lovely of his majesty, but this and the traffic management schemes are based upon absurdities because there is no climate crisis. The Earth was warmer in the recent and distant past. It also warmed faster in the past.

  1964. This is nonsense. It was hotter in the recent and distant past. There is no satellite data before 1979, and there was no real network of temperature stations outside Europe and America before the 1950s, so "hottest ever" is not very long! It was much hotter in America in the 1930s. Heatwaves were more than 6 times worse with greater frequency and covering a larger area (Kunkel, 2022, EPA). Further back the Vikings grew barley on Greenland, which is impossible today. This is bull meant to scare people into giving up their prosperity. Satellite data shows the Earth is continuing to warm at around one-tenth of a degree Celsius per decade. If we didn't have thermometers we couldn't even notice it.

  1965. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  1966. @Niko257x  Oh dear, you poor thing. Just because you lack the ability to find the material I clearly referenced doesn't make it a lie. You also appear to have trouble discerning exactly the points I'm trying to make. For example although there is evidence for a mild warming, I did not say that was "human caused". You are putting words in my mouth. That's naughty. I gave referenced evidence that this was a good thing e.g. reduced mortality from extreme temperatures. The point I'm trying to make in this commentary is that the warming that is occurring is within the rate and range of what has occurred in the recent past. Again without reference to it being "human caused". Dramatic changes in climate are perfectly natural and normal on this planet and have never required any human input. Your use of Wikipedia as a reference source is laughable: a schoolboy error. It is probably the kernel of your problem. You don't (or can't) go back to the original sources of data and evaluate them. You just take what you're given. When it comes to "the warming" I can quote you upwards of 100 recent peer reviewed published scientific papers that show both qualitatively and quantitatively that the Medieval Warm Period was hotter than the Current Warm Period. Around 1700AD the Little Ice which again was a global event reached its nadir with temperatures possibly 2°C lower than present. Warming proceeded hesitantly from that point (so before the onset of the Industrial Revolution). With initial rapid warming then a cooling in the earlier 1800s, followed by rapid warming again in the early part of the 20th century where the average daily maxima records were set (1930s) and remain extant to this day. There followed a general cooling in the mid-century which lasted until the latter 1970s. Since that point there has been a hesitant warming of 0.13°C per decade (UAH v6). My précis of the Current Warm Period is a little simplistic for brevity as it has been neither consistent nor rapid both temporally and spatially. The warming isn't even "global", and I can reference data on that if you wish. When it comes to extreme weather e.g. hurricanes, there's little or no change. The reason begin there's been some warming at the northerly latitudes but not in the tropics, so the temperature gradient across the northern hemisphere (that drives the wind) is reduced. "Basic thermodynamics". Don't take my word for it: From the NOAA GFDL website 'Global Warming and Hurricanes, An Overview of Current Research' (dated Feb. 9, 2023). And I quote "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes."
    1
  1967. @Niko257x  Well if we're quoting. How about some quotes from the UN's IPCC AR6? "There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions." "There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions." "Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)." There is no objective observational evidence that we are living through a global climate crisis. None.
    1
  1968. @Niko257x  And just so we are clear in detail, I will repeat the UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change: Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution. Agricultural Drought: 31 out of 45 global regions low confidence in observed trend (14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence). Ecological Drought as above. Hydrological Drought: 38 out of 45 global regions low confidence in observed trend. 43 out 45 low confidence in human attribution (2 medium confidence, no high confidence). So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising! There is no objective observational evidence that we are living in a global climate crisis.

  1969. Methane (CH4) is only 0.00019% (1.9 parts per million) of the atmosphere. Both of its narrow absorption bands occur at wavelengths where H2O is already absorbing substantially. Hence, any radiation that CH4 might absorb has already been absorbed by H2O. With the concentration of water vapour in the atmosphere being between 1,000 and 20,000 times greater than CH4, the effects of CH4 are completely masked by H2O.

  1970. Everything we do releases carbon dioxide, so they want to control everything. There will be global starvation if fossil fuels are eliminated. At risk in coming decades will be half of the world’s 8.5 billion to 10 billion people who are fed by crops grown with fertilizers derived from fossil fuels. Getting to Net Zero by 2050 would cost $9.2 trillion a year globally (McKinsey). That's not going to be good value for money. That's nearly one-tenth of global GDP. That money would be better spent on a myriad of things including educating the fifth of humanity who are illiterate and represent a 7% annual loss to the world's economy. Any country that attempts it will be indebted or impoverished. Example: For the UK to reach net zero by electrification of its transport fleet and heating system, it will require a tripling (as a minimum) of its current electrical generation capacity among other things. This will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the Earth. 10,000 child slaves in the cobalt mines of the Congo not enough for you? Make it a million. Imagine all the human suffering and environmental damage done from all that resource extraction! An electric vehicle requires 6 times the mineral input compared to a conventional one, and the carbon cost is greater until you reach 80,000 miles. Production of all of these minerals has been mastered by China: a totalitarian communist regime that thinks nothing of the mass murder of its own citizens, imagine how much it cares about the rest of us. And why are we embarking on this great net zero crusade? For what? So someone can virtue signal by driving around in a Tesla. Maddeningly, there is no climate crisis. The Earth was warmer in the recent and distant past.

  1971. @Erndea  Obviously someone forgot to tell the corals living in the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’. It shows no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool – the hottest major water mass on earth. They couldn't have got the memo!

  1972. It was b*ll*cks then, and it's b*ll*cks now. As regards ocean acidification, it is estimated that the ocean’s global mean surface pH may have declined (i.e., become less alkaline and thus more “acidic”) by -0.07 to -0.08 in the last 200 years — from pH8.12 during pre-industrial times to 8.04 to 8.05 today (Wei et al, 2015). N.B. The decline in pH occurred before 1930. However, and very importantly when you look the data after CO2 emissions began rising precipitously in the 1930s, the oceans have become less “acidic”!!! By way of comparison, from one season to the next, or over the course of less than 6 months, pH levels naturally change by ±0.15 pH units, or twice the overall rate of the last 200 years. On a per-decade scale, the changes are even more pronounced. Oceanic pH values naturally fluctuate up and down by up to 0.6 U within a span of a decade, with an overall range between 7.66 and 8.40. This is decadal rate of pH change is larger than the overall 200-year span (0.07-0.08) by a factor of 8.

NOAA: "We conclude that the historical Atlantic hurricane data at this stage do not provide compelling evidence for a substantial greenhouse warming-induced century-scale increase in: frequency of tropical storms, hurricanes, or major hurricanes, or in the proportion of hurricanes that become major hurricanes." NOAA data 1851-2021 shows no trend in number of hurricaine landfalls with the record high being 1886. The trend for over 7 decades has been downwards in the Pacific as well. Drought appears to be decreasing globally measured by SPI 1901-2017. Global trends show no increasing flooding frequency or severity. For every million people on earth, annual deaths from climate-related causes have declined 98%. Deserts have shrunk considerably since the 1980's. The Sahara shrank by 12,000km² per year 1984-2015. The Earth has greened by 15% or more in a human lifetime. The Great Barrier Reef's coral cover has reached the greatest extent ever recorded. On extinction the rate is very low: 900 known lost species for 2.1 million known species in 500 years, so from observations there are an average of slightly less than 2 species lost every year. Global temperatures maxed out in 2016 and have been lower ever since. There is no climate crisis.

  1979.  @janmajnik6889  It is just weather. It changes. There is no objective observational evidence that we are living in a global climate crisis. The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed: Air Pollution Weather (temperature inversions), Aridity, Avalanche (snow), Average precipitation, Average Wind Speed, Coastal Flood, Agricultural drought, Hydrological drought, Erosion of Coastlines, Fire Weather (hot and windy), Flooding From Heavy Rain (pluvial floods), Frost, Hail, Heavy Rain, Heavy Snowfall and Ice Storms, Landslides, Marine Heatwaves, Ocean Acidity, Radiation at the Earth’s Surface, River/Lake Floods, Sand and Dust Storms, Sea Level, Severe Wind Storms, Snow, Glacier, and Ice Sheets, Tropical Cyclones. There is no objective observational evidence that we are living through a global climate crisis. None.

  1980. @cyberfunk3793  Global burned area has decreased by one quarter this century! The World is burning less. For the whole of Canada, there is no trend in burn acreage for the period 1980-2021. The previous highest burn acreage was in 1989. Over that same period the trend for number of fires was slightly downwards (CNFDB). Note that 2020 had the lowest recorded burn acreage and number of fires, so can that record be attributed to man-made climate change? Burn acreage was much, much, higher in the US during the 1920's, 30's and 40's. It peaked in 1930 at well over 50,000,000 acres. The trend is downwards (1926-2020 NIFC US) eventhough CO2 has increased exponentially. For 2000 onwards the average burn acreage is much less than 10,000,000 acres. The number of fires has also declined. Remember CO2 was increasing all the time. Burn area for US so far in 2023 including Maui is 3rd lowest on record. Data for Siberia seems harder to come by. However, for the period 1997-2016, the trend was highly variable (by a factor of 4) but the trend for the annual burn acreage was downwards (Global Fire Data). For the Amazon (2003-2019), 2010 was the record year for fire emissions with all subsequent years lower by at least ½. When it comes to wildfires there is nothing unusual about this summer's fire season in Europe (look it up on the EFFIS website). Besides all this the forest fire record in Southern Europe is related to the previous winter rains, not summer temperatures. Wetter winters encourage more plant grow, which forms more fuel for fires when it dries out. Mediterranean summers are always hot and dry enough to allow fires to spread. Furthermore, with regard to the IPCC, they have not detected or attributed the number of fires or the burn acreage to man-made climate change. Also IPCC only has medium confidence ( that's a 50-50, so toss a coin) that weather conditions that promote wildfires (fire weather) have become more probable in southern Europe, northern Eurasia, the USA, and Australia over the last century. Note that annual Global Wildfire Carbon Emissions have been declining dramatically since 2003, with 2022 being the lowest on record (Copernicus). "With higher CO2, increased tree cover leads to reduced fire ignition and burned area, and provides a positive feedback to tree cover" (Chen et al, 2019), so burning fossil fuels actually leads to less forest fire! Global burned area has decreased by nearly by 24.2% in 20 years (Chen et al, 2023). The World is burning less! There is no climate crisis...there isn't even any evidence for it.

  1981. The retreat of Himalayan glaciers began before the current warming and was caused by reduced precipitation (Shekhar, 2017. Singh, 2020.). This supported by further work done by Schneider (2014), and Chen (2019). The retreat was due to a reduction in precipitation. Currently, precipitation is half of what it was 20 years previously. Research by Salerno (2015) "challenges the assumption of the main driver [i.e. temperature] of glacier mass changes". Satellite data shows the glaciers in the Karakoram largely unaffected by current warming. Of 1219 glaciers surveyed, 79.5% were stable, 5.3% were advancing, and 7.6% retreating (Rankl, 2014). Swiss Alps glacier extents were smaller than 2000 C.E. during the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer (Schimmelpfennig et al., 2022). Glaciologists Bohleber et al, 2020 of the Austrian Academy of Science discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago. There is “no evidence” that Jostedalsbreen, a southern Norway glacier, even existed during the first several thousand years of the Holocene, or when CO2 hovered near 260 ppm (Winker, 2021). There is no objective observational evidence that we are living in a global climate crisis. Glacial retreat is certainly not evidence of this.

  1987. @SincerelyFromStephen  The British took a continent of people in which life for everybody was ugly brutish and short, plagued by the prospect of unremitting warfare, and the arbitrary exercise of power by self-appointed despots. Britain changed India into a land at Independence gifted with internal peace, the Law, Democracy, property rights, a growing population with improving health and education, a modern transportation system, and a developing economy. You're welcome. It took the Indians another 50 years before they made any real progress when left to their own devices. Largely because they were foolish enough to colonise themselves with another, much worse form of western imperialism, planned economy Marxism. The Indians were truly fortunate to have the British as the facilitators of their development for as long as they did.

  1988. The Royal Society recommend the UK should have 100TWh of energy storage by 2050 (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. A typical pumped storage facility has a 300 to 400m dam built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming huge amounts of copper and other rare metals for the next 25 years. 1.5 billion tonnes of concrete 42 million tonnes of steel (which is going to need 27 million tonnes of coking coal) 1.9 million tonnes of copper 1.3 million tonnes of zinc 184,000 tonnes of manganese 122,000 tonnes of chromium 56,000 tonnes of nickel 54,000 tonnes of other critical minerals. No doubt all of these materials will be ethically sourced using low carbon processes. Nuclear power would require less than ½ of these resources and Coal power around ¹/10th. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the less than 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the whole Earth going Net Zero. Good luck with that.
