Observational constraints project a ~50% AMOC weakening by end of this century

"AMOC" = Atlantic Meridional Overturning Circulation, a system of ocean currents that transports warm and salty water into the North Atlantic via upper-ocean currents.

Changes to the AMOC will strongly influence future climates in the Atlantic and beyond. A key consequence of an AMOC slowdown, among many others, is the equatorward shift of the intertropical convergence zone, which will lead to the drying out of the Sahel region and put pressure on its agriculture and food security...
