AMOC Tipping point

A sudden shift in the strength of the Atlantic meridional overturning circulation (AMOC) is thought to be the most important mechanism behind several past abrupt changes in the climate. AMOC transports heat, salt, and nutrients throughout the Atlantic Ocean. Paleoclimate evidence has shown that changes in its strength affect the climate worldwide. Whether AMOC could suddenly shift again depends on whether the circulation can exist in more than one stable state.
