Because the East Antarctic ice sheet is over 10 times larger than the West Antarctic ice sheet and located at a higher elevation, it is less vulnerable to climate change than the WAIS. In the 20th century, EAIS had been one of the only places on Earth which displayed limited cooling instead of warming, even as the WAIS warmed by over 0.1 °C ...
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 ...
[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 ...
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.
Antarctica as a whole has low sensitivity to climate change because it is surrounded by the Southern Ocean, which is more effective at absorbing heat than any other ocean due to the currents of the Southern Ocean overturning circulation, [33] [34] very low amounts of water vapor (which conducts heat through the atmosphere) [32] and because of ...
The recent warmth has posed a significant problem to the continent’s crucial ice sheet. Antarctica lost a staggering 280% more ice mass in the 2000s and 2010s than it lost in the 1980s and 1990s ...
Greater warming of this ocean water increases ice loss from Antarctica, and also generates more fresh meltwater, at a rate of 1100-1500 billion tons (GT) per year. [38]: 1240 This meltwater from the Antarctic ice sheet then mixes back into the Southern Ocean, making its water fresher. [39]
Diagram of ice–albedo feedback. Ice reflects more light back into space, whereas land and water absorb more of the sunlight. Ice–albedo feedback is a climate change feedback, where a change in the area of ice caps, glaciers, and sea ice alters the albedo and surface temperature of a planet. Because ice is very reflective, it reflects far ...
