Antarctica may have just hit an all-time record high temperature of 64.9 degrees Fahrenheit.
Scientists at Argentina's Esperanza research station in Antarctica reported the record-breaking heat on Thursday. It's important to note: the record reflects the temperature at a single location, not the entire continent.
The record hasn't been confirmed by the World Meteorological Organization, but it would beat a 2015 high of 63.5 F. NPR reports the verification process could take up to nine months.
A WMO official said in a statement that the short-term cause of the heatwave is likely related to "a rapid warming of air coming down a slope/mountain." The WMO says the Antarctic Peninsula, where the record temperature was recorded, is one of the fastest-warming parts of the planet.
The heatwave comes after NASA and NOAA declared 2019 the second-hottest year on record. Scientists have concluded the trend is largely caused by human activity, with pollution putting increasing carbon dioxide and other greenhouse gases into the atmosphere.
Correction: A previous version of this story said 2019 was the hottest year on record. It was the second-hottest year. This story has been updated.
