[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 ...
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.
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 Antarctic sea ice cover is highly seasonal, with very little ice in the austral summer, expanding to an area roughly equal to that of Antarctica in winter.It peaks (~18 × 10^6 km 2) during September (comparable to the surface area of Pluto), which marks the end of austral winter, and retreats to a minimum (~3 × 10^6 km 2) in February.
Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. If all the land-ice covering Antarctica were to melt — around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice — the seas would rise by over 60 m (200 ft ...
That flow has been increasing “dramatically” since the 1990s as the glacier gets thrown out of balance by warm air, water and a lack of snow, and is unable to recharge its ice, CNN previously ...
