Antarctic sea ice extent has fallen dramatically since 2015 after decades of slight expansion, with two new studies attributing the decline to warming ocean water brought to the surface by stronger winds rather than atmospheric heating alone. The research suggests that climate change has intensified storm systems that drive wind-powered upwelling of circumpolar deep water, overwhelming the protective freshwater layer created by increased precipitation and potentially establishing a new, sustained decline in Antarctic sea ice.
