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).
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 next world record low temperature was a reading of −88.3 °C (−126.9 °F; 184.8 K), measured at the Soviet Vostok Station in 1968, on the Antarctic Plateau. Vostok again broke its own record with a reading of −89.2 °C (−128.6 °F; 184.0 K) on 21 July 1983. [8] This remains the record for a directly recorded temperature.
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 warmest day on record for the entire planet was 22 July 2024 when the highest global average temperature was recorded at 17.16 °C (62.89 °F). [20] The previous record was 17.09 °C (62.76 °F) set the day before on 21 July 2024. [ 20 ]
Pending the final data, in Vostok the value of -20.3 °C set the new monthly record but also exceeds the maximum of February (-22.2 °C on 2009, day 6) and November (-22.0 °C on 1974, day 23) pic ...
According to the World Meteorological Organization in Geneva, the new record high temperature on continental Antarctica is a downright pleasant 63.5 degrees Fahrenheit (17.5 degrees Celsius). The ...
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 ...
