Record winter temperatures in Antarctic raise fears over speed of climate breakdown
Temperatures in the Antarctic climbed above 15C this month, shattering the previous winter heat record for the usually frozen region and raising concerns about the speed of climate breakdown.
The new winter peak temperature was logged by the Argentinian Esperanza base on the Trinity peninsula on 6 June amid a protracted heatwave, when the maximum daily temperature exceeded zero degrees for three consecutive weeks.
Scientists 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.”
...
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.
