We used 11 different satellite missions to track Antarctica’s contribution to rising sea levels. Antarctica has lost nearly 3 trillion tonnes of ice since 1992 Skip to main content
Because the East Antarctic ice sheet is over 10 times larger than the West Antarctic ice sheet and located at a higher elevation, it is less vulnerable to climate change than the WAIS. In the 20th century, EAIS had been one of the only places on Earth which displayed limited cooling instead of warming, even as the WAIS warmed by over 0.1 °C ...
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]
Ice loss from the West Antarctic Ice Sheet (along with much smaller losses from the East Antarctic Ice Sheet adds meltwater to the Southern Ocean, at a total rate of 1100–1500 billion tons (GT) per year. [8]: 1240 This meltwater is fresh, and when it mixes with ocean water, the ocean becomes fresher (less salty) as well. [76]
As for the ice-sheet thaw, Greenland and Antarctica lost 38% more ice from 2011 to 2020 than in the previous decade. It also said that sea level rise has accelerated during the decade because of ...
Record-breaking low levels of sea ice around Antarctica in 2023 may have been influenced by climate change, scientists have said. Researchers at the the British Antarctic Survey (BAS) analysed ...
The ice dome known as Dome Argus in East Antarctica is the highest Antarctic ice feature, at 4,091 metres (13,422 ft). It is one of the world's coldest and driest places—temperatures there may reach as low as −90 °C (−130 °F), and the annual precipitation is 1–3 cm (0.39–1.18 in).
NASA reports that since the late 1970s, the Arctic has lost an average of 20,800 square miles (53,900 square kilometres) of sea ice per year while the Antarctic has gained an average of 7,300 square miles (18,900 km 2) of sea ice per year. At the same time, the Arctic has been losing around 50 cubic kilometres (gigatons) of land ice per year ...
