Here, we remove ocean forcing in three ice-sheet models, finding that Pine Island re-advances, but Thwaites continues to lose ice. Thwaites is responding to a historical perturbation, and its historical mass loss cannot be reversed by ocean cooling alone over centennial, policy-relevant timescales.
