Cold Atlantic Patch Signals Potential Weakening of Ocean Conveyor
A large cold patch nicknamed the 'cold blob' south of Greenland is cooling the North Atlantic by about 2°F since 1900, suggesting the Atlantic Meridional Overturning Circulation (AMOC) is weakening due to warming and fresh water from melting ice; a significant slowdown or collapse could raise U.S. East Coast sea levels, bring colder European winters, and trigger droughts in Africa.
