DescriptionAntarctic Temperature Trend 1981-2007.jpg
Map showing Antarctic Skin Temperature Trends between
1981 and 2007. Skin temperature is roughly the top one
millimeter of land, sea,
snow, or ice. Across most of the
Antarctic the temperature increased, in some areas warming approaching 2 degrees
Celsius during the period. The map is based on thermal
infrared (heat) observations made by a series of
NOAA satellite sensors. None of the sensors were in
orbit at the same time, so
scientists could not compare simultaneous observations from different sensors to make sure each was recording temperatures exactly the same. Instead, the team checked the
satellite records against ground-based
weather station data to inter-calibrate them and make the 26-year satellite record. The level of uncertainty is between 2 and 3 degrees Celsius. The most dramatic changes are the red areas associated with
icebergcalving and the collapse of the
Larsen B ice shelf. In these cases, the
satellites saw a change from cold ice to relatively warm
open water.
