Scientists from the University of South Florida,along with colleagues in Canada and the Netherlands, have determined that the influx of fresh water from the Greenland ice sheet is "freshening" the North Atlantic Ocean and could disrupt the Atlantic Meridional Overturning Circulation (AMOC), and an considerable component of global ocean circulation that could have a global effect. Researchers say it could impact the future climate in places such as portions of Europe and North America.
