The earth will find a new equilibrium. It will even be survivable by humans, no doomsday, no problem. But maybe not for a technical civilization. Back to a sustainable number of people, maybe a few hundred thousand or a few millions.

Research of climate history has found that the last few 10s of thousands of years had an unusually stable climate. It is speculated that this has made development of large early cultures and the eventual rise of our technological society possible.

We are going to end this phase, it seems. Of course, sooner or later it would have ended anyway but we are pushing the end forward.
