I don't know and I don't think that anybody does. An issue is, even if Polar Bears could "evolve back to warmer conditions", how long would they take? Could they do so before becoming extinct?

"Its all a storm in a teacup anyway, IMO"

It may be, but as I pointed out we don't know for sure. Intuition is often a bad source for determining outcomes.

There have been many periods through history when there was little or no arctic ice. They survived fine then. On land.
