SummaryA mysterious cold patch in the North Atlantic has puzzled scientists for years.New research links the cooling to a weakening system of Atlantic Ocean currents that researchers warn could reach a tipping point.The shutdown of these currents would bring catastrophic changes to weather and climate across multiple continents.AI-generated summary was reviewed by a CNN editor.In the North Atlantic Ocean, south of Greenland and Iceland, a large patch of water is doing something very strange. While the rest of theocean heats up, it’s been getting colder. A newstudysays it has the answer to this mystery — and it’s an ominous sign the world is hurtling toward one of themost alarming climate tipping points.The swath of ocean — dubbed the “cold blob” or “warming hole” — has cooled bynearly 1 degree Celsius(1.8 Fahrenheit) since 1900.Scientists have long debated whether this anomaly is driven by heat loss from the ocean surface due to changes to winds and clouds, or whether it’s a signal of the weakening of acritical system of ocean currents, which transports heat. The new research concludes it’s the latter, andthe finding points to a worrying future.☔️ ☀️Explore CNN Weather for iPhoneThe Atlantic Meridional Overturning Circulation, or AMOC, works like a vast ocean conveyor belt, pulling warm water from the tropics to the Northern Hemisphere, where it cools, sinks and flows back south.A raft of research suggests this system is weakening as human-driven global warming melts ice and causes a surge of freshwater into the ocean, disrupting the AMOC’s delicate balance of heat and salinity. Some scientists warn the AMOC is headingtoward a tipping point, potentially as early at this century, which would mean a future collapse is locked in.An AMOC shutdown would be aglobal catastrophe, causing accelerated sea level rise on the US East Coast, plunging Europe into a winter deep freeze and shifting the monsoon in Africa, driving prolonged droughts.AMOC IMPACTSCAPE MAY, NEW JERSEY -
