An analysis of 20 years' worth of real-life observations supports recent U.N. computer predictions that by 2050, summer sea ice off Alaska's north coast will probably shrink to nearly half the area it covered in the 1980s, federal scientists say.

Antarctic glaciers are thinning and slipping ever faster into the sea, according to several new studies. Warmer air and sea temperatures are blamed, and the changes are expected to cause an appreciable rise in sea levels.

Summer sea ice will probably recede 300 to 500 miles off Alaska's north coast by 2050, compared to the 1980s when ice packs were only 30 to 50 miles off the coast, and decrease to half the size. Mammals dependent on the sea ice, such as polar bears, and fishermen will suffer. Federal scientists compared computer simulations of how warming would affect sea ice with 20 years' of observations.
