For more than a century, a patch of cold water south of Greenland has resisted the Atlantic Ocean's overall warming, fueling debate among scientists. A new study identifies the cause as the long-term ...

A new study projects that the Atlantic Meridional Overturning Circulation (AMOC)—the system of currents that includes the Gulf Stream—could shut down after 2100 under high-emission scenarios. This ...

The critical system of ocean currents which loops around the Atlantic Ocean is weakening and could be far closer to collapse than previously thought, according to two new studies — an event which ...

A century-old mystery of a stubborn cold patch in the North Atlantic is finally being unraveled. A new study links this anomaly to a long-term weakening of the Atlantic Meridional Overturning ...

In the North Atlantic Ocean, south of Greenland and Iceland, a large patch of water is doing something very strange. While the rest of the ocean heats up, it’s been getting colder. A new study says it ...
