NOAA Affirms Sea Ice Will Shrink in Half
122924
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.
