people will starve to death before any mass movement. I cant see china or russia opening themselves up. Things would get bad. Africa would become a giant desert and southern india along with almost all of africa would become too hot to live in too hot to grow things mass desert.
Russia and canada have the most legitimate claims to most of the arctic. Russia´s claim of the basin is also legitimate. The americans though you can be sure are going to try super hard to try and convince canada to go against its own best interests in terms of range of extended claims. Canadians have valid claims to a larger share then what meets the eye.
they do only to an extent like the links talk about. I mean i guess it would be a while until massive amounts of land are lost to rising sea. They do take steps to lower emissions and have since the soviet days they know pollution is bad. But yes there are those including Putin who say the human toll is overstated.
I wonder to if Xi is same way and is only paying lip service to his ´fight´against it. The US i think had valid concerns when they said that so many powers are exempt from the same standards they have until a certain year.
