Gulf Stream could be veering toward irreversible collapse, a new analysis warns

One of the most crucial ocean current systems for regulating the Northern Hemisphere’s climate could be on the verge of total collapse due to climate change, a new study has revealed.

The Atlantic Meridional Overturning Circulation (AMOC), which includes the Gulf Stream and is responsible for moderating large parts of the world’s climate, has undergone “an almost complete loss of stability over the last century”, according to a new analysis. The currents work like a conveyor belt to transport warm, salty water northward from the tropics and cold water back south along the seafloor. This giant conveyor belt had already been shown to be at its weakest in more than a thousand years, but now it could be veering toward a total breakdown.
