===South Pole=== {{See also|Climate of Antarctica}} [[File:Antarctica 6400px from Blue Marble.jpg|thumb|A satellite composite image of Antarctica]] Earth's [[South Pole|south polar]] land mass, [[Antarctica]], is covered by the [[Antarctic ice sheet]]. It covers an area of about 14.6 million km<sup>2</sup> and contains between 25 and 30 million km<sup>3</sup> of ice. Around 70% of the [[fresh water]] on Earth is contained in this ice sheet. Data from the National Snow and Ice Data Center shows that the sea ice coverage of Antarctica has a slightly positive trend over the last three decades (1979β2009).<ref>{{cite web |url=http://nsidc.org/sotc/sea_ice.html |title=State of the Cryosphere / Arctic and Antarctic Standardized Anomalies and Trends Jan 1979 β Jul 2009 |publisher=National Snow and Ice Data Center |access-date=24 April 2010 |archive-date=26 December 2012 |archive-url=https://web.archive.org/web/20121226153100/http://nsidc.org/cryosphere/sotc/sea_ice.html |url-status=dead }}</ref>
