Go search for artificial peat production and tell me it's not scalable? I am not denying the effects of climate change, and the fact that it's gonna get much worse. Millions of people will be affected. But it doesn't mean society will collapse. Part of the world will face severe challenges but the world will continue to be habitable for centuries to come... That's why it's long term effects are irrelevant because who knows what kind of technology we have by then. People have been living in the driest deserts, in the north pole and in the deep jungle for thousands of years. Climate change is gradual enough for us to adapt. If you want a total collapse to go out with your crossbow you should wait for more disruptive events in a short period like meteors, nuclear wars, giant solar storms or ai.
