There are several reasons to expect that climate changes in the Arctic and Antarctic are emphasized. First, the ice-albedo feedback loop where initial warming causes snow and ice to melt, exposing darker surfaces of the ice, which absorbs more sunlight, leading to more warming Second, because cooler air is more dense and holds less water vapour than warmer air, in the Arctic, a larger portion of radiation absorbed by the surface of the ice goes directly into warming the atmosphere, compared to somewhere else, particularly closer to the equator, where a larger portion of radiation goes into the process of evaporation. Third, a reduction in ice area will lead to more energy being transferred from the ocean to the atmosphere, which yet again, causes even more warming. Finally, changes in the atmospheric and oceanic circulation patterns caused by global temperature increase may cause more heat to be transferred to the Arctic, emphasizing Arctic and Antarctic warming
