When we talk about global warming at the poles the Arctic tends to get more press than the Antarctic because its happening faster there than anywhere else on Earth. Greenland and Antarctica are currently both pushed downwards by the weight of the ice on top.

Two-thirds of Antarctica is a high cold desert.

The massive West Antarctic ice sheet holds something like 6 percent of the worlds fresh water frozen in its guts. In the West Antarctic Peninsula 2001-2002 atmospheric conditions resulted in thicker sea ice compacted against the edge of the peninsula with increased melting at the edge releasing large quantities of fresh water and ice algae directly into the upper mixed layer of the ocean.
