A vital Atlantic Ocean current that helps regulate global climate may be on the verge of collapse. Scientists warn the Atlantic Meridional Overturning Circulation (AMOC), which includes the Gulf Stream, could shut down within decades if emissions remain high.

The AMOC acts like a conveyor belt, moving warm tropical waters north. It keeps winters in Europe and the U.S. Northeast milder. But if it fails, experts say the result could be freezing winters, rising sea levels, and massive disruptions to weather worldwide.

“The tipping point may come in the next few decades, which is very concerning,” said Stefan Rahmstorf of the University of Potsdam. Another researcher added, “The shutdown risk is more serious than many people realize.”

A collapse would also threaten fisheries, shift hurricane paths, and increase flooding risks along the U.S. East Coast. Scientists stress urgent action is needed. “Cutting emissions fast is the only way to reduce this risk,” experts warned.
