Taking stock of arctic sea ice and climate [PDF]

, 2009
The relationship among the cause-and-effect of the Arctic atmosphere, sea ice, and ocean is discussed. The increased vulnerability of the Arctic system to anomalous atmospheric forcing can be argued from the perspective that recent ice loss is the result
