The Atlantic Meridional Overturning Circulation, a planetary-scale current system that redistributes heat across the globe, has weakened to its lowest point in at least 1,000 years. A growing body of research suggests it may be approaching a tipping point — but scientists remain sharply divided on the timeline, with projections ranging from collapse by mid-century to continued gradual decline through 2100 and beyond.
