Deep in the Atlantic, a large flow of water moves heat from warm areas near the tropics toward Greenland. This flow is called Amoc. It works far below the sea, so many people do not see it. New studies say it may be getting weaker. If it slows more, winters in northern Europe could become much colder even while the world gets warmer. Rain patterns in the tropics could also change. Sea level could rise suddenly along the US east coast. Still, this ocean flow is hard to show in pictures. News stories often use clear images to help people understand climate change, but Amoc has very few simple images.

A deep ocean current may be getting weaker
A large flow of water in the Atlantic moves heat north. New studies say it may be getting weaker. If it slows more, winters in northern Europe could be much colder, monsoons could change, and sea level could rise on the US east coast.
