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 ...
Antarctica has the lowest naturally occurring temperature ever recorded: −89.2 °C (−128.6 °F) at Vostok Station in 1983. [4] It is also extremely dry (technically a desert , or so called polar desert ), averaging 166 millimetres (6.5 in) of precipitation per year, as weather fronts rarely penetrate far into the continent.
The weather in Antarctica can be highly variable, and weather conditions will oftentimes change dramatically in a short period of time. Weather conditions on the continent are classified in a number of ways, and restrictions placed upon workers and other staffs vary both by stations and by nations.
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
Antarctica lost a staggering 280% more ice mass in the 2000s and 2010s than it lost in the 1980s and 1990s, according to a 2019 study published in the Proceedings of the National Academy of Sciences.
A British Army medical officer who attempted to become the fastest woman to ski alone across Antarctica hopes her feat will show people “you can do anything”.
The dry wind evaporates the snow rapidly and little melts into the soil. During the summer, this process can take only hours. Another important factor is a lack of precipitation. Precipitation averages around 100 millimetres (4 in) per year over a century of records, almost [3] [4] exclusively in the form of snow. This contributes to the low ...
[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 ...
