Ocean heat under Antarctica melts ice shelves from below, risking faster sea-level rise
TL;DR Summary
A new study shows circumpolar deep water heat is migrating toward Antarctica, melting ice shelves from below and potentially accelerating global sea-level rise. By combining decades of ship data with Argo floats, researchers built a 40-year record of warming that also suggests deeper changes in ocean circulation, which could affect currents like the AMOC and have broad climate impacts.
