The arctic has been ice-free in the past. Those that adapt to new conditions will reproduce, carrying on their genetic lines. If none adapt, then it was their time to go as a species. Did anyone mourn the extinction of cave bears in Europe? Most species that ever existed are extinct now. The idea that we must preserve each and every living species is pretty silly.
