The Antarctic is a high, cold ice sheet surrounded by ocean, while the Arctic is an ocean surrounded by land. Because of its geography, the Arctic is inherently warmer than the Antarctic. Only a small rise in temperature in the Arctic can lead to a large changes in the melting of snow and ice, initiating climate feedbacks to amplify the warming.

THE ARCTIC TUNDRA is a winter wonderland where the snowy season prevails. Traditionally, the snowpack has left the ground exposed to sun for only a few months of the year—sometimes only for several weeks. Some years, summer fails to arrive entirely. The Arctic tundra has always been a mosaic of different snow habitats.
