The loss of West Antarctica ice would take at least 500 years and possibly as long as 13,000 years. [107] [108] 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. [109]
Of the continent's 162 ice shelves, 68 show significant shrinking between 1997 and 2021, while 29 grew, 62 didn’t change and three lost mass but not in a way scientists can say shows a ...

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 ...

During the last glacial period, Antarctica was blanketed by a massive ice sheet, much as it is today. The ice covered all land areas and extended into the ocean onto the middle and outer continental shelf. [33] [34] Counterintuitively though, according to ice modeling done in 2002, ice over central East Antarctica was generally thinner than it ...
