Arctic and Antarctic Sea Ice Extent, 1979-2007: Although Arctic sea ice extent underwent a strong decline from 1979 to 2007,
Antarctic sea ice underwent a slight increase. The Antarctic ice extent increases were smaller in magnitude than the Arctic
increases, and some regions of the Antarctic experienced strong declining trends in sea ice extent. See the Arctic Sea Ice
FAQ for more information. Image provided by National Snow and Ice Data Center, University of Colorado, Boulder.
