In the middle of the Antarctic winter, during months of darkness when temperatures often dip below −30°C, the continent warmed dramatically. In July and August 2024, temperatures in parts of East Antarctica rose by up to 28°C above average and stayed high for more than two weeks. To put that in perspective, a similar anomaly in the UK would push January temperatures into the mid-30°Cs. In a recent study, colleagues and I show the Antarctica heatwave was not simply unusual weather. It was a rare atmospheric disturbance, amplified by human-caused climate change, offering a glimpse of what could become more...
