Antarctic Sea Ice Increasing, NASA Confirms

Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? Since the late 1970s, its extent has been relatively stable, increasing just slightly; however, regional differences are observed. A NASA/NOAA/university team found that two persistent geological factors — the topography of Antarctica and the depth of the ocean surrounding it — are influencing winds and ocean currents, respectively, to drive the formation and evolution of Antarctica’s sea ice cover and help sustain it. --NASA/JPL News, 20 May 2016
