Today, as warming waters caused by climate change flow underneath the floating ice shelves in Pine Island Bay, the Antarctic Ice Sheet is once again at risk of losing mass from rapidly retreating glaciers.

The study also suggests that the accelerated melting of mountain glaciers in recent decades may explain a phenomenon that has long puzzled scientists — why Arctic and sub-Arctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall.

The height of these cliffs made them unstable, triggering the release of thousands of icebergs into Pine Island Bay, and causing the glacier to retreat rapidly until its grounding line reached a restabilising point in shallower water.

This means that as glaciers recede, warm water quickly rushes in to melt more ice.

It is doing so because it is concerned about its environment: the air quality in its cities, the water it is dependent on from the melting glaciers of the Himalayas.

The study fuels a growing concern among scientists about the factors affecting the Antarctic ice sheet — namely, that warm ocean waters are helping to melt glaciers and drive greater levels of ice loss, particularly in West Antarctica.

But scientists increasingly attribute much of the observed grounding line retreat — particularly in West Antarctica — to the influence of warmer ocean water seeping beneath the ice shelves and lapping against the bases of glaciers, melting the ice from the bottom up.
