Warm water beneath grounded ice accelerates retreat.
CorroboratedContext
An ice-sheet model incorporating seawater intrusion across Thwaites Glacier’s grounding zone projects up to 30 mm of sea-level rise by 2100, twice previous estimates, without additional warming. Warm water beneath grounded ice accelerates melting and retreat; simulations estimate a 60% probability of detachment from a stabilizing ridge by 2100.

Beneath steeply sloping parts of the ice the water remained warm and the ice contained scallop features from strong melting.
