No, I’m not talking about tipping points.
I’m talking about the fact that we’ve already released a ton of carbon and we can’t get it back out of the air. The carbon itself isn’t the global warming. The heat it traps is. Even if we stop emissions right this second, the carbon already in the air will continue trapping heat as long as it’s there. Natural cycles will take centuries to remove it.
I am not sure that is how carbon induced greenhouse effect works. The warming has pretty immediate effects and is pretty correlated with the amount of CO2 in the atmosphere. The only warming beyond that (as I understand it) is from positive feedback loops via these tipping points. All else being equal (and without tipping points) if we stopped emitting carbon today, the rise in temperature would also stop relatively quickly. And if we did find a way (by some miracle) to remove carbon from the atmosphere it would start to cool again relatively quickly.
