摘要

The coastal areas of Antarctica are sites of strong air-sea-ice interactions that can affect the entire globe, but they remain the least-studied region on Earth with respect to climate variability. The paper by Shevenell et cd. (page 250 of this issue1) is a good start in addressing that deficiency. The western Antarctic Peninsula is warming five times faster (3.4 °C per century2) than the global mean increase during the twentieth century. The consequences are evident in the changing distribution of plants and animals, and in the retreat and sometimes dramatic disintegration of ice shelves. But there are all too few data to assess the causes of this warming, and to judge how unusual it is in recent Earth history. Satellites have been continuously monitoring sea surface temperatures (SSTs) and ice extent on the Antarctic Peninsula for only the past three decades. Globally, the instrumental record covers just the past few hundred years, with notably sparse data coverage for the Southern Ocean and Antarctica.
