  2. Antarctic ice sheet - Wikipedia

    en.wikipedia.org/wiki/Antarctic_ice_sheet

    The loss of West Antarctica ice would take at least 500 years and possibly as long as 13,000 years. [110] [111] Once the ice sheet is lost, the isostatic rebound of the land previously covered by the ice sheet would result in an additional 1 m (3 ft 3 in) of sea-level rise over the following 1,000 years. [112]

  3. Antarctic sea ice - Wikipedia

    en.wikipedia.org/wiki/Antarctic_sea_ice

    The Antarctic sea ice cover is highly seasonal, with very little ice in the austral summer, expanding to an area roughly equal to that of Antarctica in winter.It peaks (~18 × 10^6 km 2) during September (comparable to the surface area of Pluto), which marks the end of austral winter, and retreats to a minimum (~3 × 10^6 km 2) in February.

    en.wikipedia.org/wiki/Geography_of_Antarctica

    Some 98% of Antarctica is covered by the Antarctic ice sheet, the world's largest ice sheet and also its largest reservoir of fresh water. Averaging at least 1.6 km thick, the ice is so massive that it has depressed the continental bedrock in some areas more than 2.5 km below sea level; subglacial lakes of liquid water also occur (e.g., Lake ...

    [14] [15] In 1978, it was believed that the loss of the ice sheet would cause around 5 m (16 ft 5 in) of sea level rise, [90] Later improvements in modelling had shown that the collapse of the ice grounded below the sea level would cause ~3.3 m (10 ft 10 in) of sea level rise, [102] The additional melting of all the ice caps in West Antarctica ...

  7. Climate of Antarctica - Wikipedia

    en.wikipedia.org/wiki/Climate_of_Antarctica

    Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water . If all the land-ice covering Antarctica were to melt — around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice — the seas would rise by over 60 m (200 ...

  8. Ice sheet - Wikipedia

    en.wikipedia.org/wiki/Ice_sheet

    Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
