Rapid melting of Antarctic sea ice largely driven by ocean warming

Published: 18 March 2026
A study using 110,000 ocean profiles reveals that thinning of a cold subsurface layer and strong Southern Ocean storms in 2015 allowed warm deep water to reach the surface, triggering rapid Antarctic sea ice loss.
