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

@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.

@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.

@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.

@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.
