It seems likely mass relocations will be reactive, and the areas where people try to relocate will fight hard not to accept desperate people. Look at Europe right now, where refugees are being deliberately drowned so countries don’t have to accept more people. And that’s before these problems become widespread.

The suffering directly caused by climate change will be bad - homelessness, starvation, lack of water, deadly heat and storms, etc. But we will add to that suffering when the whole world starts fighting over it.
