Ancient ocean sediments link changes in currents to cooling of Northern Hemisphere 3.6 million years ago

New research from an international group looking at ancient sediment cores in the North Atlantic has for the first time shown a strong correlation between sediment changes and a marked period of global cooling that occurred in the Northern Hemisphere some 3.6 million years ago. The changes in sediments imply that profound changes in the circulation of deep water currents occurred at this time.
