Extended Climate Projections Sharply Raise Risk of AMOC Tipping Within Decades

The Atlantic's chilling secret: A century of data reveals ocean current collapse

A century-old mystery of a stubborn cold patch in the North Atlantic is finally being unraveled. A new study links this anomaly to a long-term weakening of the Atlantic Meridional Overturning Circulation (AMOC) a massive ocean current system that regulates climate across the Northern Hemisphere. Using over 100 years of temperature and salinity data, researchers showed that only models with a weakening AMOC could recreate the observed changes. Th…

Possible North Atlantic overturning circulation shutdown after 2100 in high-emission future

Under high-emission scenarios, the Atlantic Meridional Overturning Circulation (AMOC), a key system of ocean currents that also includes the Gulf Stream, could shut down after the year 2100. This is the conclusion of a new study, with contributions by the Potsdam Institute for Climate Impact Research (PIK). The shutdown would cut the ocean’s northward heat supply, causing summer drying and severe winter extremes in northwestern Europe and …
