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.

@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.

@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?

@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.

@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. 🙄
