Well Into Antarctic Fall, Esperanza Base (Peninsula) Records 63.5F; Poss. Continental Record High
The coldest place on Earth just got warmer than has ever been recorded. According to the weather blog Weather Underground, on Tuesday, March 24, the temperature in Antarctica rose to 63.5°F (17.5C) a record for the polar continent. Part of a longer heat wave, the record high came just a day after the previous record was set at 63.3°F.
Tuesdays temperature was taken at the Argentinas Esperanza Base, located near the northern tip of the Antarctic Peninsula. The Monday record was from Marambio Base, about 60 miles southeast of Esperanza. Both are records for the locations, however the World Meteorological Organization is yet to certify that the temperatures are all-time weather records for Antarctica. Before these two chart-toppers, the highest recorded temperature from these outposts was 62.8°F in 1961.
Setting a new all-time temperature record for an entire continent is rare and requires the synthesizing of a lot of data. As Weather Undergrounds weather historian, Christopher C. Burt, explains, there is debate over what exactly is included in the continent Antarctica, and by the narrowest interpretation, which would include only sites south of the Antarctic Circle, Esperanza would not be part of the continent.
According to the WMO, the official keeper of global temperature records, the all-time high temperature for Antarctica was 59°F in 1974. As Mashable reports, the verification process for these new records could take months as the readings must be checked for accuracy.
