Fulfilling ‘Feedback Loop’ Fears, New Study Shows Melting Ice Could Spell Disaster Faster Than Previously Thought

As Antarctica's ice sheets melt, a new study finds, they may be contributing to further melting of glaciers in a "feedback loop." (Photo: Ronald Woan/Flickr/cc)

When cold surface water no longer sinks into the depths, a deeper layer of warm ocean water can travel across the continental shelf and reach the bases of glaciers, retaining its heat as the cold waters remain above. This warmer water then rapidly melts the glaciers and the large floating ice shelves connected to them.
