Scientists say mysterious cold spot in Atlantic could signal pending climate disaster
WFSB • • science
Key Points:
- Scientists have identified a "cold blob," a large patch in the North Atlantic Ocean near Greenland, that has cooled nearly 2 degrees Fahrenheit since 1900, contrasting with record hot temperatures elsewhere in the ocean.
- The cold spot is believed to signal a weakening of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system that moves warm water northward, cools it, and returns it south.
- Human-induced warming is melting ice caps, releasing cold, fresh water into the ocean, which disrupts the AMOC's delicate balance and contributes to its weakening.
- A complete shutdown of the AMOC could lead to severe climate impacts, including rising sea levels on the U.S. East Coast, colder winters in Europe, and extended droughts in Africa.
