The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi). It is the largest of Earth's two current ice sheets, containing 26.5 million cubic kilometres (6,400,000 cubic miles) of ice ...
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.

These retreats would have added about 0.5 m (1 ft 8 in) and 0.9 m (2 ft 11 in) to sea level rise. [25] The East Antarctic ice sheet is far more stable than the West Antarctic ice sheet. The loss of the entire East Antarctic ice sheet would require global warming of between 5 °C (9.0 °F) and 10 °C (18 °F), and a minimum of 10,000 years.
The Thwaites Glacier Tongue, or Western Glacier Tongue (75°0′S 106°50′W) was a narrow, floating part of the glacier, located about 30 mi (48 km) east of Mount Murphy. [28] It was the first part of the glacier to be mapped, [1] based on 65,000 aerial photographs collected during Operation Highjump in 1947. Back then, it was about 95 km (59 ...
Sea ice in the Antarctic region has fallen to a record low this year as a result of rising global temperatures and there is no quick fix to reverse the damage done, scientists said on Tuesday in a ...
Record-breaking low levels of sea ice around Antarctica in 2023 may have been influenced by climate change, scientists have said. Researchers at the the British Antarctic Survey (BAS) analysed ...
Pine Island Glacier. Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica's ice loss. [3] The glacier ice streams flow west-northwest along the south side of the Hudson Mountains into Pine Island Bay, Amundsen Sea, Antarctica. It was mapped by the United States ...
February 27, 2023 at 1:43 PM. Antarctic sea ice has likely shrunk to a record low, US scientists announced on Monday, raising concerns that the climate crisis is increasingly destabilising the ...
