[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 ...
The Ross Ice Shelf is the largest ice shelf of Antarctica (as of 2013, an area of roughly 500,809 square kilometres (193,363 sq mi) [1] and about 800 kilometres (500 mi) across: about the size of France). [2]
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.

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
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.
In 2023, the Antarctic sea ice reached record-low levels, with over 2 million square kilometres less ice than usual during winter – about 10 times the size of the UK.
The East Antarctic Ice Sheet (EAIS) lies between 45° west and 168° east longitudinally. It was first formed around 34 million years ago, [3] and it is the largest ice sheet on the entire planet, with far greater volume than the Greenland ice sheet or the West Antarctic Ice Sheet (WAIS), from which it is separated by the Transantarctic Mountains.
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]
