With man's effect on the planet creating the chance of a possible change in habitable places (down the road) for humans due to climate change, I'd like to get an idea of where one could front-run the above, and have the best possible chance of adjusting to a new world- if that's what the future holds for us.
Large waves of human migration aren't anything new; they were a common happening in the lives of our early human ancestors during the shifting from ice age to interglacial- and back, but the locals didn't always welcome the newcomers with open arms.
What country suits itself the most in regards to changes created by man-made climate change, and what other changes might arise?
