Climate warming amplified the 2020 record-breaking heatwave in the Antarctic Peninsula
February 2020 was anomalously warm in the Antarctic Peninsula region and registered one of the most intense heatwaves ever recorded in Western Antarctica. The event featured unprecedented regional mean temperature anomalies (+4.5¿°C) over the Antarctic Peninsula between 6 and 11 February 2020 and th...
