[74] [75] [76] According to one study, if the Paris Agreement is followed and global warming is limited to 2 °C (3.6 °F), the loss of ice in Antarctica will continue at the 2020 rate for the rest of the 21st century, but if a trajectory leading to 3 °C (5.4 °F) is followed, Antarctica ice loss will accelerate after 2060 and start adding 0.5 ...
[8] [9] [10] According to one study, if the Paris Agreement is followed and global warming is limited to 2 °C (3.6 °F), the loss of ice in Antarctica will continue at the 2020 rate for the rest of the 21st century, but if a trajectory leading to 3 °C (5.4 °F) is followed, Antarctica ice loss will accelerate after 2060 and start adding 0.5 ...
A new study suggests the melting of Antarctica’s ice sheet, driven by the climate crisis, may increase volcanic activity under the surface. ... may increase volcanic activity under the surface ...
The West Antarctic Ice Sheet (WAIS) is the segment of the continental ice sheet that covers West Antarctica, the portion of Antarctica on the side of the Transantarctic Mountains that lies in the Western Hemisphere. It is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice ...
Antarctica is actually gaining ice mass thanks to snow and instead of driving sea level rise, it may actually be slowing it down.
Feedbacks associated with sea ice and snow cover are widely cited as one of the principal causes of terrestrial polar amplification. [12] [13] [14] These feedbacks are particularly noted in local polar amplification, [15] although recent work has shown that the lapse rate feedback is likely equally important to the ice-albedo feedback for Arctic amplification.

Changes in the elevation of Lake Superior due to glaciation and post-glacial rebound. During the last glacial period, much of northern Europe, Asia, North America, Greenland and Antarctica were covered by ice sheets, which reached up to three kilometres thick during the glacial maximum about 20,000 years ago.
The absolute minimum for the loss of West Antarctica ice is 500 years, and the potential maximum is 13,000 years. [83] [84] Once ice loss from the West Antarctica is triggered, the only way to restore it to near-present values is by lowering the global temperature to 1 °C (1.8 °F) below the preindustrial level.
