Antarctica: Temperatures above 30 C above normal

Eastern Antarctica recorded exceptionally high temperatures this week, 30 degrees Celsius higher than normal, experts said on Twitter.

The Concordia Research Station, located in the Dom C of the Antarctic Plateau at an altitude of more than 3,000 meters, recorded a record “heat” of -11.5 degrees Celsius on Friday, “breaking an all-time high of 13.7 சாதனை on December 17, 2016,” Météo said. -France forecaster Etienne Kapikian tweeted.

Although it is not possible at the exact moment that an event is the cause of climate change, one of the clearest signs of global warming is the amplitude and intensity of heat waves.

The poles are warming faster than the planet’s average, averaging +1.1 ° C above pre-industrial times.

The eastern Antarctic heat wave was caused by satellite measurements in late February 1979, when the Antarctic Ocean ice reached its smallest area of ​​less than 2 million square kilometers, according to the U.S. Center for Snow and Ice Data.
