There was hot weather when the dinosaurs roamed the earth didn’t ya know.
Er, precisely the point.
The Earth is a balanced system. It is full of negative feedback loops that regulate things and keep it stable. Were that not the case, the climate would have spiralled out of control - turning into an ice ball, or all the atmosphere boiling off - billions of years ago. It hasn't.
Think of it like a bowl spinning on top of a stick. If the bowl is the normal way up, balanced precariously, and you knock the bowl and it falls off. With the bowl upside down, it wobbles but then settles down again and stays on. It's a stable system. Same with the earth: increase CO2, you increase plant growth, which accelerates CO2 absorption and things stabilise again.
We've dumped a shed load of CO2 into the atmosphere recently but it's still at 426 parts per million. That 0.0426%. It's a pitifully small amount. 500 million years ago, it was more than 10x this amount, and life is still here.
Anyway, since we've increased CO2 by 50% over the last 200 years, it takes the planet time to adjust. In another 100 years or so, it will have mopped up all the excess CO2 and temperatures will start dropping again. We'll possibly end up with another mini ice age.
This is not just some bollocks on a football forum, btw. You can read up about it if you like.
