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 ]
From 1992 to 1996, the two ice sheets – which hold 99% of the world’s freshwater ice – were shrinking by 116 billion tons (105 billion metric tons) a year, two-thirds of it from Antarctica.
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 ...
The recent warmth has posed a significant problem to the continent’s crucial ice sheet. Antarctica lost a staggering 280% more ice mass in the 2000s and 2010s than it lost in the 1980s and 1990s ...
Proponents of flood geology hold to a literal reading of Genesis 6–9 and view its passages as historically accurate; they use the Bible's internal chronology to place the Genesis flood and the story of Noah's Ark within the last 5,000 years. [4] Scientific analysis has refuted the key tenets of flood geology.

As of October 2019, it continues to be monitored due to the threat it could pose to shipping channels. An adjacent ice formation, nicknamed the "loose tooth", was originally predicted to calve from the ice sheet between 2010 and 2015. [5] In February 2020, D-28 was lodged against the edge of the shelf, and slowly drifting northwards.
