I'm interested as to why the arctic climate is changing faster than anywhere else? Can anyone mention any mechanisms or theories behind this (apart from the albedo effect) or recommend any papers?
I think, decreasing albedo due to shrinking sea ice might play a role. Also a denser cloud canopy as result of intensified evaporation might reflect infrared radiation back to the ground in winter. Greening of the Arctic also changes albedo. And methane degassing from thawing permafrost could strengthen the greenhouse effect locally.
