An AMOC weakening by 15 % thus cools the region at a rate of 0.15 x 10 14 W and according to model simulations can fully explain the observed cooling trend (2).

The AMOC is a big deal for climate. The Atlantic meridional overturning circulation (AMOC) is a large-scale overturning motion of the entire Atlantic, from the Southern Ocean to the high north.
