NASA warning as ‘world’s most dangerous glacier’ to COLLAPSE after HUGE cavity found

Many Antarctic glaciers extend for miles beyond their grounding lines, floating out over the open ocean.

Just as a grounded boat can float again when the weight of its cargo is removed, a glacier that loses ice weight can float over land where it used to stick.

When this happens, the grounding line retreats inland, exposing more of a glacier’s underside to sea water, increasing the likelihood its melt rate will accelerate.

“We are discovering different mechanisms of retreat,’ Mr Milillo said.

These results highlight that ice-ocean interactions are more complex than previously understood.
