The last time the atmosphere changed in composition by a comparable amount to the last 250 years, Cyanobacteria was colonizing the ocean and photosynthesizing, injecting O2 into the atmosphere and causing one of 6 recorded mass extinctions. Now granted, this was at a fraction of the speed, it took place over a few thousand years, a lightning flash in geologic terms, and changed the composition by a smaller percentage make up.

So yes, the biosphere has seen changes in the past, even within humanities timescale. But not by this amount and this abruptly. To say there have been “worse” ecological changes in the past is obfuscation of the crisis we’re in.

what are you gonna do about it, aside from brigading this sub?

covid lockdowns didnt put much of a dent in co2 emissions.

personally i think there is 0 chance you could put a gov into power either democratic or authoritarian which would reduce emissions as much as you want

realistically that leaves geoengineering. which would probably be a lot easier to do with AI.

oh yeah and of course VR would help too but you just cant help but shit on people who are trying XD
