The article discusses a new study published in Science Advances suggesting that the Atlantic Meridional Overturning Circulation (AMOC) could weaken by 51% by 2100. It presents the findings alongside perspectives from other scientists who emphasize that the intensity of this slowdown remains a subject of ongoing scientific debate.

Wikipedia and multiple web sources confirm that the AMOC is a system of currents that transports warm water from the tropics northward to redistribute heat.
