New Research Refines Projections for Atlantic Meridional Overturning Circulation Slowdown

A new research article by Valentin Portmann et al. addresses discrepancies in climate models regarding future projections of the Atlantic Meridional Overturning Circulation (AMOC). By integrating a large set of observable variables and correcting a bias in South Atlantic surface salinity, the study refines the estimate of AMOC slowdown to 51 ± 8% by 2100, with a 90% probability. This work contributes to a more precise understanding of a critical component of Earth's climate system.
