Antarctic Winter Heat Wave Raises Concerns for Future Climate
• East Antarctica experienced an unprecedented heat wave in July-August 2024, with temperatures soaring 28°C above average.
• A weakened polar vortex and an atmospheric river brought warm, moist air to Antarctica, contributing to the extreme warming.
• Human-induced climate change is believed to have intensified the heat wave, making such events more likely in the future.
Antarctica heat wave caused by multiple factors
In July and August 2024, East Antarctica experienced an extraordinary heat wave, with temperatures reaching 28°C above average. This unprecedented event was caused by a weakened polar vortex and an atmospheric river that transported warm, moist air deep into the continent. The heat wave was further amplified by record-low sea ice levels and unusually warm Southern Ocean temperatures.
