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). [22]
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 ...
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.
Two temperature records were set on February 6, one in each hemisphere, one for warmth, the other for mind-numbing cold. On Feb. 6, 2020, five years ago, Antarctica set its all-time record high of ...
With detailed weather station and satellite data dating back only about 40 years, scientists wondered whether these events meant Antarctica had reached a tipping point, or a point of accelerated ...
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.
In December 1868 and then in February 1869 Ivan Khudyakov made the discovery of the Northern Pole of Cold by measuring a record temperature of −63.2 °C (−81.8 °F) in Verkhoyansk. Later, on January 15, 1885, a temperature of −67.8 °C (−90.0 °F) was registered there by Sergey Kovalik .
An Antarctic glacier the size of Florida is on the verge of collapse, scientists with the American Geophysical Union warned Monday, a nightmare scenario made worse by climate change that could ...
