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 ...
Antarctic surface ice layer temperature trends between 1981 and 2007, based on thermal infrared observations made by a series of NOAA satellite sensors.. Climate change caused by greenhouse gas emissions from human activities occurs everywhere on Earth, and while Antarctica is less vulnerable to it than any other continent, [1] climate change in Antarctica has been observed.

In Antarctica, average summer temperatures were about 10 °C. [25] The East Antarctic Ice Sheet (EAIS) was severely reduced in area, [26] [27] and it may have occupied as little as 25% of its present volume. [28] However, despite its diminished size and its retreat away from the coastline of Antarctica, the EAIS remained relatively thick. [29]
In comparison, the subantarctic islands have precipitation of 100–200 cm (39–79 in) per year and the dry interior of Antarctica is a virtual desert with only 10 cm (3.9 in) precipitation per year. [20] The climate in and around the Antarctic Peninsula is changing dramatically in 2024.
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 ...
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. [1]
Virtually the entire international climate modeling community has participated in this project since its inception in 1990. AMIP is endorsed by the Working Group on Numerical Experimentation (WGNE) of the World Climate Research Programme , and is managed by the Program for Climate Model Diagnosis and Intercomparison with the guidance of the ...
