The Atlantic Ocean's current system, an engine of the Northern Hemisphere's climate, could be weakening to such an extent that it could soon bring big changes to the world's weather, a scientific study said on Thursday.
The Atlantic Meridional Overturning Circulation (AMOC) is a large system of ocean currents which transports warm water from the tropics northward into the North Atlantic.
As the atmosphere warms due to increased greenhouse gas emissions, the surface ocean beneath retains more of heat. A potential collapse of the system could have severe consequences for the world's weather systems.
