A premise of this website is that the earth will warm by approximately 4°C by the end of this century. But what if it will be more? The amount of possible feedback loops (permafrost thawing, boreal and tropical forests burning, et cetera), adjusted climate models, oceans that have absorbed more heat than previously thought and the ‘faster than expected’ mantra we keep hearing every week, make it ever more plausible that by the end of the century the earth will be spiraling up towards a ‘hothouse earth’.
So, where to migrate to then? The best advice is probably to get away from the masses. If things get really bad food will be scarce and people tend to turn on one another. The director of the Potsdam Institute for Climate Impact Research declared that at 4°C warming “It’s difficult to see how [the earth] could accommodate a billion people or even half of that.” In such or worse scenarios horde after horde of desperate people will plunder and try to hold any piece of viable land and the very limited resources that are left.
Canada and Russia are both massive and sparsely populated. A warmer climate might mean more agricultural possibilities in these countries. So moving there might offer the best chances for survival. Although, with no Arctic sea ice and a meandering (polar) jet stream, conditions might get worse even there.
Or, counterintuitively, go to a place where people will definitely not flock to. The Siberian and Inuit people still exist because other people were not interested in their land and scarce resources, while mainstream native Americans had to bear the full brunt of colonization. Would you rather struggle against nature or against your fellow man? As some users of the subreddit r/collapse suggest: “So go to a desert or to the Antarctic. Pick the most inhospitable place possible, were it’s not just hard to survive, but a life or death struggle even for the prepared. Congratulations, come collapse of civilization you will not have to worry about looters since they’ll never survive to get there. The environment will be your only foe and you will be well adjusted before and ready as can be before the rest collapses.“
