Climate Science: Stability of Atlantic Ocean Currents

A recent study suggests that the total collapse of the Atlantic Meridional Overturning Circulation (AMOC), a crucial system of ocean currents that regulates climate, is unlikely to occur this century. However, a significant weakening remains probable, which could have serious consequences such as increased floods, droughts, faster sea level rise, and more severe storms, affecting billions globally. The study utilized 34 advanced climate models and found that while AMOC may slow significantly, it is unlikely to collapse entirely due to Southern Ocean winds maintaining water movement. Researchers emphasize the importance of continued efforts to curb global warming, as even a significant weakening of AMOC could cause major climate disruptions. More detailed observations and improved models, particularly of the Southern and Pacific Oceans, are needed to better inform future projections and policy decisions.
