Contrary to the findings of previous studies, much of Antarctica has warmed in recent decades — and it has done so substantially, at rates similar to the global average rise in temperature.
Most Antarctic weather stations, with the exception of those at the South Pole and Lake Vostok, lie along the coast of the forbidding continent, says Eric Steig, a climatologist at the University of Washington in Seattle. Although coastal regions, on average, have warmed in recent decades, weather stations at the South Pole and Lake Vostok in the continent’s interior — two data points that represent an area the size of the lower 48 United States — have cooled. “Lacking more data, scientists have presumed that most of the surrounding area was cooling as well,” says Steig.
Now, to assess long-term climate trends for the entire icy continent, Steig and his colleagues blended meteorological data from 42 weather stations available since 1957 with satellite data gathered since 1982.
The researchers report in the Jan. 22 Nature that most of Antarctica, like much of the rest of the world, has substantially warmed in recent decades.
