- fighterpilot 5y agoI have a question which might betray ignorance - why wouldn't humans still be able to live in colder countries which are now warm countries? I agree that 5-8C warming will lead to mass death through war, famine. But why would Siberia be too hot for habitation for the remaining population (whether that's 100 or 500 million people)?
- TomSwirly 5y agoSome humans will survive. There are a lot of us and it's a big planet. When permafrost melts, it turns into a bog. Over decades and centuries, many of those bogs would dry out, but most of Siberia will be one great big morass for generations after it melts.
- he_is_legend 5y agoYou can't grow food and crops in suddenly warmed up permafrost earth. Generating nutrient rich soil takes a long time (decades to centuries for long lasting results). Global temperature rises are happening too fast.
- jl6 5y agoNot true. The Paleocene-Eocene Thermal Maximum was this hot, or even hotter, and life was thriving. But not human life. Could humans survive this? Probably yes - we are resourceful and adaptable. But probably with a vastly smaller population and with a type of civilization radically different to our own.
