In a recent paper published in Reviews of Geophysics, UMass Distinguished Professor Raymond Bradley synthesized information from lake sediments, stalagmites, and offshore marine sediments to provide a comprehensive record of changes over the past ?70,000 years. He and coauthor Henry Diaz describe how freshening of the subpolar North Atlantic led to a rapid reduction in the northward flux of heat by the ocean, subsequent reorganization of the atmospheric circulation, and, in turn, climate modifications in various parts of the world.

Huge Stores of Arctic Sea Ice Likely Contributed to Past Climate Cooling
In a new paper, Alan Condron (Woods Hole Oceanographic Institution), CSRC Director Ray Bradley, and graduate student Anthony Joyce propose that massive amounts of melting sea ice in the Arctic drained into the North Atlantic and disrupted climate-steering currents, thus playing an important role in causing past abrupt climate change after the last Ice Age.
