Summary:
-
Temperature Surge in Antarctica: Over the past month, ground temperatures across vast regions of Antarctica’s ice sheets have soared to an average of 10°C above normal. This significant increase has been termed a near-record heatwave, with some days witnessing temperatures 28°C higher than expected.
-
Global Heat Records: This heatwave occurs during a period of 12 consecutive months of record warmth globally, with temperatures consistently surpassing the critical 1.5°C rise above preindustrial levels. This threshold is considered crucial to avoiding the worst impacts of climate change.
-
Impact and Predictions: Michael Dukes, forecasting director at MetDesk, emphasized that while individual high temperatures are noteworthy, the persistent average rise over the month is far more alarming. Climate models have long predicted severe impacts on polar regions due to anthropogenic climate change, and this heatwave exemplifies those predictions. Sustained warming could lead to significant ice sheet collapses, contributing to global sea-level rise and further climate disruptions.
