  1. Nonsense.

  2. 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.

  3. 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.

  4. 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). 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.

  5. He hasn't read his own report. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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!

  10. 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.

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

And the fires of 2023 seem to have been largely started by arsonists.

  17. @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.

  18. 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.

  19. 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.

  21. 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.

  23. 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.

  24. 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.

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).

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.

  28. @Milan Kovitch  I'm story if you don't like the truth, but NOAA data shows Artic summer minimum levelled off in 2007. Maybe you could cite some alternative research.

  30. ​@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.

  31. 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.

  32. 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.

  33. @hosnimubarak8869  You're right of course about the last point. The temperature maxed out in 2016.

  34. @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.

  35. @allan339  And 2022 had the fifth lowest ACE value. There is no upward trend in the data. It fits better with the AMO.

  36. @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.

  40. 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.
