NASA images depict rapid loss of thick Arctic sea ice

These satellite images, released by NASA, show that the thickest Arctic sea ice — formed over many years — has gone from covering most of the Arctic basin in winter in 1980 to covering only about a third of the basin by 2012. In the images, shown above, multi-year Arctic sea ice is shown in bright white, while thinner sea ice — often less than two years old — is shown in light blue and milky white. By 2012, thick Arctic sea ice had retreated to an area north of Greenland and Canada’s Arctic Archipelago. (Images courtesy of NASA)
