flag Strong storms and warm oceans caused sudden Antarctic sea ice loss by disrupting ocean layers, defying prior climate models.

flag Unusually strong storms and warmer ocean waters caused a rapid decline in Antarctic sea ice after a record high in 2015, according to a study in Nature Climate Change. flag Researchers found that intense storms disrupted a protective cold-water layer beneath the surface, allowing warmer deep water to mix upward and accelerate ice melt. flag This breakdown in ocean stratification, driven by long-term warming and storm activity, explains the abrupt sea ice loss that climate models had failed to predict. flag The findings highlight the need for improved models and better ocean observations to understand future climate impacts.
