[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 ...
Location and diagram of Lake Vostok, a prominent subglacial lake beneath the East Antarctic Ice Sheet. East Antarctic Ice Sheet is located directly above the East Antarctic Shield – a craton (stable area of the Earth's crust) with the area of 10,200,000 km 2 (3,900,000 sq mi), which accounts for around 73% of the entire Antarctic landmass.

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 world’s largest iceberg is on the move again, drifting through the Southern Ocean after months stuck spinning on the same spot, scientists from the British Antarctic Survey (BAS) have said.
The iceberg was first spotted on 22 January by the British Antarctic Survey and was later confirmed by the U.S. National Ice Center (USNIC) using satellite imagery. [ 3 ] As of 31 March 2023, the iceberg was located at 76°48' South and 33°41' West and had a length of 28 nautical miles and width of 25 nautical miles.
Occurrence of blue-ice areas (dark blue) in Antarctica. Blue-ice areas were first discovered in 1949-1952 by the Norwegian–British–Swedish Antarctic Expedition. [15] They have been identified only in Antarctica, [4] although similar ice patches on Greenland have been reported [4] and blue ice is widespread at glaciers worldwide. [16]
Dome Argus is located on the massive East Antarctic Ice Sheet and is the highest ice feature of Antarctica. [3] Dome A is a lofty ice prominence, the highest rooftop of the Antarctic Plateau, and the elevation visually is not noticeable. Below this enormous dome, underneath at least 2,400 m (7,900 ft) of ice sheet, lies the Gamburtsev Mountain ...
