Polar bears did just fine during the Medieval warming period when it was several degrees warmer than now.
The huge flaw in the Warmist argument. The Warmists claim increased temps of just a few degrees will superheat the earth and wipe out life as we know it.
The record shows the earth WAS!!! several degrees warmer just about one thousand years ago. Why then wasn't all life wiped out by the increase in temps? The Warmists have no answer for that.
