Scientists say mysterious cold spot in Atlantic could signal pending climate disaster
AZ Family • • science
Key Points:
- Scientists have identified a "cold blob," a large patch of water in the North Atlantic Ocean near Greenland that has cooled nearly 2 degrees Fahrenheit since 1900, contrasting with record hot ocean temperatures elsewhere.
- This cold spot is believed to signal a weakening of the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current system that transports warm water northward and cold water southward.
- The weakening of AMOC is linked to human-induced warming, which melts ice caps and introduces cold, fresh water into the ocean, disrupting the ocean's temperature balance.
- A complete shutdown of AMOC could lead to severe consequences including rising sea levels along the U.S. East Coast, colder winters in Europe, and extended droughts in Africa.
