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.

However, since then there has been a sharp, threefold increase - between 2012 and 2017 Antarctica lost 219 billion tonnes of ice per year, a 0.6 mm per year sea level contribution. [3] Almost all of the ice lost from Antarctica has been triggered by warming oceans melting their outlet glaciers, which causes them to speed up. [3]
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. ... Earth has lost 8 ...

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.
