Record winter temperatures in Antarctic raise fears over speed of climate breakdown | Polar regions | The Guardianhttps://www.theguardian.com/environment/2026/jun/10/record-winter-temperatures-in-antarctic-raise-fears-over-speed-of-climate-breakdownScientists said the high of 15.4C broke the previous record set at the same station in 1998 by 2C. “This is absolutely crazy,” said Raúl Cordero, an Ecuadorian climate professor at the University of Groningen. “It is also about 20C above normal for this time of the year. That is a huge anomaly.”
Unusually strong warm winds from the north blew across much of the Antarctic peninsula. One Chilean weather station, Boonen Rivera, registered temperatures of close to 13C, Cordero said.
On King George Island, 100 miles (160km) from Esperanza, researchers said the landscape had changed from mostly white to brown, grey and green after temperatures hit 4.6C on 6 June.
“Last weekend was very strange. The temperatures here went very high so everything outside melted,” said Luis Muñoz, a Chilean glaciologist. “Usually there is 20cm of snow and a lot of ice on the ground at this time.”
