  2. Antarctic ice sheet - Wikipedia

    en.wikipedia.org/wiki/Antarctic_ice_sheet

    [74] [75] [76] According to one study, if the Paris Agreement is followed and global warming is limited to 2 °C (3.6 °F), the loss of ice in Antarctica will continue at the 2020 rate for the rest of the 21st century, but if a trajectory leading to 3 °C (5.4 °F) is followed, Antarctica ice loss will accelerate after 2060 and start adding 0.5 ...

  3. Antarctic sea ice - Wikipedia

    en.wikipedia.org/wiki/Antarctic_sea_ice

    Antarctic sea ice is the sea ice of the Southern Ocean. It extends from the far north in the winter and retreats to almost the coastline every summer. [1] Sea ice is frozen seawater that is usually less than a few meters thick. This is the opposite of ice shelves, which are formed by glaciers; they float in the sea, and are up to a kilometre thick.

    [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 ...

  5. Geography of Antarctica - Wikipedia

    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 ...

  6. 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 ft ...

    From 1992 to 1996, the two ice sheets – which hold 99% of the world’s freshwater ice – were shrinking by 116 billion tons (105 billion metric tons) a year, two-thirds of it from Antarctica.

  8. Antarctic Circumpolar Current - Wikipedia

    en.wikipedia.org/wiki/Antarctic_Circumpolar_Current

    Antarctic sea ice cycles seasonally, in February–March the amount of sea ice is lowest, and in August–September the sea ice is at its greatest extent. [12] Ice levels have been monitored by satellite since 1973. Upwelling of deep water under the sea ice brings substantial amounts of nutrients.

    Record-breaking low levels of sea ice around Antarctica in 2023 may have been influenced by climate change, scientists have said. Researchers at the the British Antarctic Survey (BAS) analysed ...
