The highest temperature ever recorded on Antarctica was 19.8 °C (67.6 °F) recorded at Signy Research Station, Signy Island on 30 January 1982. [2] [3] The highest temperature on the Antarctic mainland was 18.3 °C (64.9 °F) at the Esperanza Base (Argentina) on 6 February 2020. [4]
[1] May 19 - A tabular iceberg slightly larger than the size of Mallorca, dubbed A-76, calves from the Ronne Ice Shelf in Antarctica's Weddell Sea. [2] July 1 - The United Nations' World Meteorological Organization confirms that a record high temperature of 18.3 °C (64.9 °F) has been recorded in Antarctica at the Esperanza Base. [3]
It’s been a strange stretch for the icy desert at the bottom of the world. In mid-March, temperatures in parts of East Antarctica soared 70 degrees Fahrenheit
On 26 February 2021, the 1,270 km 2 (490 sq mi) Iceberg A-74 duly broke away from the north-facing shelf, separating from the edge of the shelf at the McDonald Ice Rumples along the North Rift and finally joining the Brunt-Stancomb chasm. As of 28 February, A-74 was located at 75° 13' South, 25° 41' West and measures 30 nautical miles (56 km ...
A total loss would increase the global temperatures by 0.05 °C (0.090 °F), while the local temperatures would increase by around 1 °C (1.8 °F). [ 14 ] [ 15 ] Estimates of isostatic rebound after the loss of East Antarctica's subglacial basins suggest sea level rise contributions of between 8 cm (3.1 in) and 57 cm (1 ft 10 in).
Nearly 1,500 academics, researchers and scientists specializing in Antarctica gathered in southern Chile for the 11th Scientific Committee on Antarctic Research conference this week to share the ...
Since 1959, there has been an average temperature increase of >0.05 °C/decade since 1957 across the continent, although it had been uneven. [20] West Antarctica warmed by over 0.1 °C/decade from the 1950s to the 2000s, and the exposed Antarctic Peninsula has warmed by 3 °C (5.4 °F) since the mid-20th century. [21]
A 2022 study by Nature noted that when the high is over the Drake Passage, it alongside an elongated cyclone located in the South Pacific transport warm and moist air to the southwestern Antarctic Peninsula, which is linked to record-high temperatures, extreme summertime melt, and dramatic break-ups in the Larsen Ice Shelf and eastern Antarctic ...
