Global warming will reverse itself in time as it has always.

During the Medieval Maximum period of Global Warming Europeans and Eskimos simultaneously reached Greenland via separate routes. When the Earth got colder the Europe and died out the Eskimos did not. Adapt or die.

"During the Medieval Maximum period of Global Warming Europeans and Eskimos simultaneously reached Greenland via separate routes. When the Earth got colder the Europe and died out the Eskimos did not. Adapt or die."

IIRC, the Europeans didn't actually die out, although many of them did die, but adopted Eskimo ways, as those were suitable for survival in that climate, where the European ways were not. They also intermarried with the Eskimo, so it's kind of hard to tell who has or has not got European ancestry without DNA tests.
