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]
Most in a 24-hour period: 230 centimetres (90.6 in) of snow on Mount Ibuki, Japan on 14 February 1927. [ 307 ] Most in one calendar month : 9.91 meters (390 inches) of snow fell in Tamarack, California , in January 1911, leading to a snow depth in March of 11.46 meters (451 inches) (greatest measured in North America).
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 ...
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. At the continent's edge, strong katabatic winds off the polar plateau often blow at storm force.
That's so cold scientists say it hurts to breathe. A new look at NASA satellite data revealed that Earth set a new record for coldest temperature recorded. It happened in August 2010 when it hit ...
Severe weather is possible within 24 to 48 hours; Visibility is greater than 300 metres (980 ft) Wind less than or equal to 45 knots (83 km/h; 52 mph) Air temperature and wind chill are above −60 °C (−76 °F) Weather Condition 2: Must meet all of the following criteria: Visibility is greater than 30 metres (98 ft)
The U.S.-based team used a sterile hot water drill to reach and collect samples from Lake Whillans, one of Antarctica's roughly 400 lakes, which are kept liquid by pressure, friction and the ...
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.
