had to think about this a bit. It doesn't directly affect it, but it adds to the problem of global warming by increasing the temp gradient between the higher elevation interior and the cooler, lower elevation coast. This can cause more wind and increased evaporation, and, effectively, "pull" the damp air away from the central ice sheets.

But that's just me speculating. It definitely seems counterintuitive.

Overall all the effects either make the ice caps colder or warmer. If it's colder that helps with melting ice caps. If it's warmer than that makes the north more pleasant.
