It's odd that climate change is hitting an uninhabitable areas first where it's mostly out of sight/out of mind. The permafrost is melting? Who cares? Permafrost is mostly useless, right? Arctic Ice? What good is that unless you're a polar bear? In addition, it strikes me odd because the brutal climate of the poles seemed like it would better resist change than the more moderate climates. The extreme conditions at the poles would seem to perpetuate the extremes. Doesn't happen that way apparently.
