Sea ice extent is area the integral current sum of the areas of all grid cells with at least 15% ice concentration while sea ice area is the integral sum of the product of ice concentration area of all grid cells with at least 15% ice concentration. The Arctic ice pack is the sea current arctic ice cover of the Arctic Ocean and its vicinity. The Arctic ice is highly sensitive to changes in air and ocean temperature. The Greenland ice sheet isn' t melting anywhere near as fast as you think. The Danish arctic research institutions present updated knowledge on the condition of two major arctic components of the Arctic: The Greenland Ice Sheet sheet and the sea ice.
