Circulation in the Atlantic Ocean slowing, new index finds

Sigma Xi SmartBrief | Mar 25, 2015

The circulation of the Atlantic Ocean is weakening due to the melting of the Greenland ice sheet, according to a new index described in Nature Climate Change. The index used sea-surface temperature studies along with observations to chart the circulation's course. It's the greatest slowing in more than 1,000 years and could result in cooler temperatures and more extreme weather in the Northern Hemisphere, should the trend continue, researchers say.
