North Atlantic Cold Blob Signals Slower Ocean Conveyor
TL;DR
Scientists link a persistent cooling anomaly south of Greenland—the North Atlantic 'cold blob'—to a slowdown in the Atlantic Meridional Overturning Circulation (AMOC). A weaker AMOC could reduce the ocean's heat transport, shifting weather, storm tracks, and potentially accelerating sea-level rise along the U.S. East Coast, with the strongest impacts near Greenland, Iceland, and northern Europe.
