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 ...
The loss of West Antarctica ice would take at least 500 years and possibly as long as 13,000 years. [21] [22] Once the ice sheet is lost, the isostatic rebound of the land previously covered by the ice sheet would result in an additional 1 m (3 ft 3 in) of sea-level rise over the following 1,000 years.

Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air ...
The UN weather agency said Friday that an Argentine research base on the northern tip of Antarctica is reporting a temperature that could be a record high. A base in Antarctica recorded a ...
He added that the last time the Earth was this warm was 125,000 years ago and sea levels were 6 to 9 meters higher "with quite a bit of contribution for West Antarctica." Temperature and carbon ...
This was Urquhart’s first week of running 871 miles (1,402 kilometers) over the course of 28 days in Antarctica, setting the record for the longest-ever run in a polar region.
Aerial photograph of Vostok Station, the coldest directly observed location on Earth. The location of Vostok Station in Antarctica. The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the then-Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements.
Each decade for the last five, average temperatures in the Antarctic Peninsula have risen by 0.5 °C (0.90 °F). [33] Ice mass loss on the peninsula occurred at a rate of 60 billion tons / year in 2006, [34] with the greatest change occurring in the northern tip of the peninsula. [35]
