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 ...
The lowest air temperature record, the lowest reliably measured temperature on Antarctica was set on 21 July 1983, when a temperature of −89.2 °C (−128.6 °F) was observed at Vostok Station. [ 2 ] [ 5 ] For comparison, this is 10.7 °C (19.3 °F) colder than subliming dry ice (at sea level pressure).
Extraordinary anomalies in #Antarctica lead to historic records today: -Vostok 3489m -17.7C,monthly record beaten by nearly 15C ! -Concordia 3234m -12.2C,highest Temp. on records and about 40C ...
This beat the station's former record of −88.3 °C (−126.9 °F) on 24 August 1960. [28] Lower temperatures occurred higher up towards the summit of the ice sheet as temperature decreases with height along the surface. Though unconfirmed, it has been reported that Vostok reached a temperature of −91 °C (−132 °F) on 28 July 1997. [32]
The coldest reliably measured temperature in Verkhoyansk was −67.8 °C (−90.0 °F) on February 5 and 7 of 1892. On February 6, 1933, a temperature of −67.7 °C (−89.9 °F) was recorded at Oymyakon's weather station. [5] At the time, this was the coldest reliably measured temperature for the Northern Hemisphere.
The 2024 Antarctica heat wave refers to a prolonged and significant mid-winter increase in Antarctic temperatures compared to prior winters, causing several regions of Antarctica to reach temperatures 10 °C (18.0 °F) above normal in July 2024, up to a 28 °C (50.4 °F) increase above average. The heat wave was significant for occurring during ...
Antarctic sea ice extent peaked this year on Sept. 10, when it covered 16.96 million square kilometers (6.55 million square miles), the lowest winter maximum since satellite records began in 1979 ...
By 2009, researchers were able to combine historical weather-station data with satellite measurements to create consistent temperature records going back to 1957 that demonstrated warming of >0.05 °C/decade since 1957 across the continent, with cooling in East Antarctica offset by the average temperature increase of at least 0.176 ± 0.06 °C ...
