After decades of observation, one of the profound consequences of anthropogenic global warming is the rapid rise in temperature in the Arctic, refered to as Arctic Amplification. Compared to the mid-latitudes, warming in the Arctic is twice as fast. The reason is mainly due to the positive feedback of a melting cryosphere: Darker surfaces are …[Read More]
