[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 ...
The melting of all of the ice in West Antarctica would increase global sea-level rise to 4.3 m (14 ft 1 in). [98] Mountain ice caps that are not in contact with water are less vulnerable than the majority of the ice sheet, which is located below sea level.
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.

The continent’s ice sheet is already a major contributor to rising seas, and increased volcanic activity could amplify the problem. Antarctic sea ice has been shrinking in recent years, hitting ...
The median estimated increase in sea level rise from Antarctica by 2100 is ~11 cm (5 in). There is no difference between scenarios, because the increased warming would intensify the water cycle and increase snowfall accumulation over the EAIS at about the same rate as it would increase ice loss from WAIS.

Antarctica is actually gaining ice mass thanks to snow and instead of driving sea level rise, it may actually be slowing it down. NASA says Antarctic ice may be growing after all Skip to main content
Other labels refer to the ice tongue's grounding line, and northern and southern shear zones where it's in direct contact with the ice shelf. [ 29 ] The Thwaites Glacier Tongue, or Western Glacier Tongue ( 75°0′S 106°50′W / 75.000°S 106.833°W / -75.000; -106.833 ) was a narrow, floating part of the glacier, located about 30 ...
Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
