Researchers warn of a “devastating tipping point” in currents in the Atlantic. Temperature drop of up to 30 degrees AMOC works like a kind of giant global conveyor belt.
Scientists have been warning for decades that the stability of this special circulation is at risk. “What surprised us was the speed at which the change occurred,” lead author René van Westen is quoted as saying. "We're moving in an alarming direction," says researcher Stefan Rahmstorf.
