    Well think it through. Even if the world heats up by 10°C, Antarctica will still be at a livable temperature. People will eek out an existence there like living on Mars, with greenhouses and suits to go outside. It won’t last forever though. Civilization collapse within 50 years, but full extinction will take some time.

        I have considered it as a reason his masters planted that in his head, yes. Or it could just be something he said once and then dementia latched on to it.

      yeah I don’t think it’s going to be 200 years.

      our ecosystems are a lot more fragile than you think. there are more moving parts than you think of. things like soil microbiomes and air composition. 10c would ruin everything. temperature effects everything.

      but also our climate is a lot more volatile than we previously thought. just about every year we learn about a new black swan ‘we are fucked’ from climate scientists. a new feedback loop, a new ledge we’re about to jump off. humanity might live another 100 years, in some ragged fucked capacity like you said, but it will not live 200.

        I am fully on board with you. When I said humanity would live a few hundred years I meant “there is at least one human alive in some vault somewhere.” It’s entirely possible that you are right, and it’s certain that 99% will be dead in the time you laid out, I just think that it’s surprisingly difficult to kill 100% of anything.

            Please explain how that could happen? Because it would take a hell of a lot of energy to stop the rotation of the core

              there was a theory i heard from a drunk climate scientist about heat and electromagnetism and shifting poles, referencing what I think was the curie temperature but this was a long-ass time ago.

              i don’t think it would just completely switch off, just be less.
