Circulating ocean waters of the past confuse Eric Worrall in the present, at WUWT

There was a new paper out in Science last week about past changes in ocean circulation. It's from a team led by  L. Gene Henry, a graduate student at Columbia University’s Lamont-Doherty Earth Observatory. What they were exploring was the past relationship between climate and ocean circulation in the North Atlantic, several thousand years ago. The paper focused on changes in the Atlantic meridional overturning circulation (AMOC).
