On the other hand, the East Antarctic ice sheet is far more stable and may only cause 0.5 m (1 ft 8 in) - 0.9 m (2 ft 11 in) of sea level rise from the current level of warming, which is a small fraction of the 53.3 m (175 ft) contained in the full ice sheet.
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.

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 ...
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 ...
In 2023, the Antarctic sea ice reached record-low levels, with over 2 million square kilometres less ice than usual during winter – about 10 times the size of the UK.
The East Antarctic Ice Sheet (EAIS) lies between 45° west and 168° east longitudinally. It was first formed around 34 million years ago, [3] and it is the largest ice sheet on the entire planet, with far greater volume than the Greenland ice sheet or the West Antarctic Ice Sheet (WAIS), from which it is separated by the Transantarctic Mountains.
The rate at which the Antarctic ice sheet is losing mass is accelerating [7] and the past and ongoing acceleration of ice streams and outlet glaciers is considered to be a significant, if not the dominant cause of this recent imbalance. [5] Ice streams hold serious implications for sea level rise as 90% of Antarctica's ice mass is lost through ...
A study published in Nature in 2012 by scientists from the Alfred Wegener Institute for Polar and Marine Research in Germany, and funded by the Ice2Sea initiative, predicts the disappearance of the 450,000 km 2 (170,000 sq mi) vast ice shelf in Antarctica by the end of the century which could – indirectly – add up to 4.4 mm (0.17 in) of ...
