This week, East Antarctica experienced an unusually high temperature of 30 degrees Celsius above normal, experts said on Twitter.
And the Concordia Research Base, located in Dome C on the polar plateau, at an altitude of more than 3,000 meters, recorded a record “temperature” on Friday of minus 11.5 degrees Celsius, which is an all-time record for all combined months. which broke the record on December 17 (December 17). The first) 2016 minus 13.7 degrees,” tweeted Etienne Kapikian, meteorologist for Meteo France.

Although expectations pointed to a possible drop in temperatures at the end of the austral summer, the Dumont Dorville base, on the coast of Adélie Land, registered a moderate record temperature during the month of March, reaching 4.9 degrees Celsius, while that the minimum temperature reached a record. level is also 0.2 degrees on March 18.

“Frost-free days are episodic” at Dumont d’Urville, “but never after February 22 (1991),” Gaitan Eames of Meteo France noted on Twitter.

He called this a “historic event in terms of moderation in the east” of the frozen continent, as the temperature rise hovered between 30 and 35 degrees Celsius above seasonal standards.

“Temperatures should drop rapidly at this point,” said Jonathan Will, a researcher at the Institute for Environmental Geosciences in Grenoble.

The increase and intensification of heat waves is one of the clearest signs of global warming, although it is not possible to give such an explanation to a specific climatic event when it occurs.

The temperature at the poles is rising faster than the rate at which the planet as a whole has warmed, which is about 1.1 degrees Celsius since pre-industrial times.

The heat wave in East Antarctica comes after sea ice in Antarctica in late February reached its smallest area on record, less than two million square kilometers, since satellites began recording these measurements in 1979. according to the US National Snow and Ice research center. Center.
