It is believed that the loss of the ice sheet would take between 2,000 and 13,000 years, although several centuries of high emissions may shorten this to 500 years. 3.3 m (10 ft 10 in) of sea level rise would occur if the ice sheet collapses but leaves ice caps on the mountains behind, and 4.3 m (14 ft 1 in) if those melt as well.
A map of West Antarctica. The total volume of the entire Antarctic ice sheet is estimated at 26.92 million km 3 (6.46 million cu mi), [2] while the WAIS contains about 2.1 million km 3 (530,000 cu mi) in ice that is above the sea level, and ~1 million km 3 (240,000 cu mi) in ice that is below it.

Location and diagram of Lake Vostok, a prominent subglacial lake beneath the East Antarctic Ice Sheet. East Antarctic Ice Sheet is located directly above the East Antarctic Shield – a craton (stable area of the Earth's crust) with the area of 10,200,000 km 2 (3,900,000 sq mi), which accounts for around 73% of the entire Antarctic landmass.

A Dec. 23, 2024, Facebook post (direct link, archive link) shows a map of Antarctic sea ice extent, or area, with color coding that purportedly shows ice gain and loss between Dec. 21, 2016, and ...
The Antarctic ice sheet is melting in a new, worrying way that scientific models used to project future sea level rise have not taken into account, suggesting current projections could be ...
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different ...
It shows the glacier, the ice shelf on its eastern side, and the remains of the ice tongue in the west, now reduced to a "mélange" of icebergs which is much less effective at supporting the glacier and preventing calving events. [26] Thwaites Glacier is located at the northern edge of the West Antarctic Ice Sheet, next to Pine Island Glacier.
The probes are aimed at providing more accurate data gauging the rate at which warming ocean water around Antarctica is melting the continent's coastal ice, allowing scientists to improve computer ...
