Recent research highlights an increased risk of collapse for the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current system that regulates global climate. The study, published in Science Advances, combines real-world ocean observations with climate models, projecting a potential deceleration of 42% to 58% by 2100. This slowdown could trigger catastrophic consequences worldwide, including extreme cold winters and summer droughts in Western Europe, shifts in tropical rainfall patterns, and significant sea level rises around the Atlantic.
