The melting of all of the ice in West Antarctica would increase global sea-level rise to 4.3 m (14 ft 1 in). [98] Mountain ice caps that are not in contact with water are less vulnerable than the majority of the ice sheet, which is located below sea level.
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.

The melting of all of the ice in West Antarctica would increase global sea-level rise to 4.3 m (14 ft 1 in). [24] Mountain ice caps that are not in contact with water are less vulnerable than the majority of the ice sheet, which is located below sea level.
Antarctic sea ice is increasing - that's old news - but now it's also thicker than scientists thought, and that's only adding to the confusion. A project to map Antarctic sea ice over the last ...
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 ...
Consequently, the near-surface winds steered around weather systems are thought to explain large parts of the inhomogeneous Antarctica sea-ice trends. The 2021 IPCC AR6 report confirms the observed increasing trend in the mean Antarctic sea ice area over the period from 1979 to 2014 but assesses that there was a decline after 2014, with the ...
Main drill site for the New Zealand 2017 hot water drill camp on the Ross Ice Shelf. The Ross Ice Shelf is one of many such shelves. It reaches into Antarctica from the north, and covers an area of about 520,000 km 2 (200,000 sq mi), nearly the size of France. [2] [3] The ice mass is about 800 km (500 mi) wide and 970 km (600 mi) long. In some ...
Ice, water, and mantle rocks have mass, and as they move around, they exert a gravitational pull on other masses towards them. Thus, the gravity field, which is sensitive to all mass on the surface and within the Earth, is affected by the redistribution of ice/melted water on the surface of the Earth and the flow of mantle rocks within.
