Warmer air is only part of the story when it comes to Greenland’s rapidly melting ice sheet. New research by scientists at Woods Hole Oceanographic Institution (WHOI) highlights the role ocean circulation plays in transporting heat to glaciers.

Greenland’s ice sheet has lost mass at an accelerated rate over the last decade, dumping more ice and fresh water into the ocean. Between 2001 and 2005, Helheim Glacier, a large glacier on Greenland’s southeast coast, retreated 5 miles (8 kilometers) and its flow speed nearly doubled. (more…)

WASHINGTON — Researchers looking at corals in the western tropical Pacific Ocean have found signs of a profound shift in the depth where warm surface water and colder deeper water meet—a shift predicted by computer models of global warming.

The finding is the first physical evidence supporting what climate modelers have been predicting as the effects of global climate change on the subsurface ocean circulation. (more…)
