A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster ...
A crucial system of ocean currents may already be on course to collapse with devastating implications for sea level rise global weather — leading temperatures to plunge dramatically in some ...
They include ice melt that could cause severe sea-level rise and the collapse of a crucial ocean current that governs how heat cycles in the Atlantic Ocean. Venezuela lost its final glacier this year.
Those currents comprise half of the global thermohaline circulation that includes the flow of major ocean currents, the other half being the Southern Ocean overturning circulation. [ 2 ] The AMOC is composed of a northward flow of warm, more saline water in the Atlantic's upper layers and a southward, return flow of cold, salty, deep water.

The Atlantic Meridional Overturning Circulation (AMOC), also known as the Gulf Stream System, is a large system of ocean currents. [ 70 ] [ 71 ] It is driven by differences in the density of water; colder and more salty water is heavier than warmer fresh water. [ 71 ]
Map of Labrador Current. The Labrador Current is a cold current in the North Atlantic Ocean which flows from the Arctic Ocean south along the coast of Labrador and passes around Newfoundland, continuing south along the east coast of Canada near Nova Scotia. Near Nova Scotia, this cold water current meets the warm northward moving Gulf Stream.
A system of ocean currents that transports heat northward across the North Atlantic could collapse by mid-century, according to a new study, and scientists have said before that such a collapse ...
