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.
