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.

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.

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. 😊

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.

This climate report is propaganda. These 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.

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.

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.

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

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.

@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.

Calm down. 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.

@Lies Tricks UAHv6 satellite data global mean temperature change: October 2014 to September 2022, trend minus 0.01°C (that's about minus 0.1°C a century). So sorry for being childish. I should have said it's getting cooler. Enjoy the snow. Merry Christmas.

@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.

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).

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.

@Dinty 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°.

@Dinty I've gone back to source. Actual scientific research. The boring stuff but the real stuff. The documentaries are easy on the eye, but do not have to be objective.

This is bad weather. There is no climate crisis.

@Ratigun No.

That doesn't mean to say it's happening (or has happened). NOAA tide gauge data certainly doesn't concur.

@byronchavarria4954 I'm fine using the Imperial system of measurement, and use it in woodworking and construction, but the data and science generally uses S.I. units so I stick to those for discussions. 3mm is approximately ¹/10 of an inch.

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.

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.

@emotown1 What would you prefer?

@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.

@HealingLifeKwikly if it's on Wikipedia it must be right.
1
@HealingLifeKwikly so what has stopped this positive feedback effect in the past. Shouldn't the Earth carry on warming for ever? Why did warming happen first and increase in CO2 happen after in the climate record?
1
@HealingLifeKwikly You cannot be this precise to one hundredths of a degree it's ridiculous. Especially given the paucity of data. The increase in CO2 has caused a change in the energy budget of a few watts per metre squared. That's less than a cloud moving across the sky. Calm down. The world's not coming to an end.
1
@HealingLifeKwikly My friend is a farmer. Him and I have seen lots of weather. The only change in the climate he has noticed in 50 years is the growing season is slightly longer in some years. A few days. Maybe a week. That's it. That's all of it. It's a good thing if it's happening. Get over it. 🙄
