A temperature of 15.4C was logged at Argentina’s Esperanza base on the Antarctic Trinity peninsula on 6 June, breaking the previous winter record at the same station from 1998 by 2C and sitting roughly 20C above the seasonal norm. During the protracted heatwave, daily maxima at Esperanza stayed above 0C for three consecutive weeks, a Chilean station on the peninsula registered close to 13C, and researchers on King George Island observed surface melting that changed the landscape from white to brown, grey and green while rain fell on the Collins glacier.
