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]
Antarctica may have up to 17,000 species; [108] while 90% of the ocean around Antarctica is deeper than 1,000 m (3,281 ft), only 30% of the benthic-sample locations were taken at that depth. [109] On the Antarctic continental shelves , bethnic-zone biomass may increase due to oceanic warming, which is likely to be of most benefit to seaweed .
Record of atmospheric temperature taken from EPICA ice core in Antarctica. The Antarctic Cold Reversal (ACR) was a climatic event of intense atmospheric and oceanic cooling across the southern hemisphere (>40°S) between 14,700 and 13,000 years before present that interrupted the most recent deglacial climate warming (c. 18,000-11,500 years BP).
Here's cold comfort: You could be in East Antarctica which new data says set a record for soul-crushing cold. Try 135.8 degrees Fahrenheit below zero. Better yet, don't. That's so cold scientists ...
Lake Vostok (Russian: озеро Восток, romanized: ozero Vostok) is the largest of Antarctica's 675 known [3] subglacial lakes.Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level.
East Antarctica is colder than its western counterpart because of its higher elevation. Weather fronts rarely penetrate far into the continent, leaving the centre cold and dry, with moderate wind speeds. Heavy snowfalls are common on the coastal portion of Antarctica, where snowfalls of up to 1.22 m (48 in) in 48 hours have been recorded.
Nearly 200 nations faced a Monday deadline to file what the United Nations' climate chief calls “among the most important policy documents governments will produce this century” — their ...
Antarctica is the largest ice desert in the world. Some 98% of Antarctica is covered by the Antarctic ice sheet , the world's largest ice sheet and also its largest reservoir of fresh water . Averaging at least 1.6 km thick, the ice is so massive that it has depressed the continental bedrock in some areas more than 2.5 km below sea level ...
