warming hole? the ocean's heart?

Atlantic ocean currents are weakening - and it could make the climate in some regions unrecognizable Live Science - April 25, 2025
A mysterious patch of water in the North Atlantic has baffled scientists for decades. Located to the southeast of Greenland, this blob of seawater was colder between 1901 and 2021 than during the late 1800s, even as the seas around it became ever warmer. Some scientists linked this "warming hole" to an inflow of frigid Arctic meltwater; others blamed pollution from shipping, which can bounce the sun's rays back into space. But a growing body of evidence suggests the hole has a more sinister origin - one whose impacts, if unleashed, would reach much farther than a small region of the North Atlantic. The warming hole might be a sign that Atlantic Ocean currents are slowing down. This network of currents regulates Earth's climate, moving heat from the tropics to the Northern Hemisphere. The currents, which include the Gulf Stream, form a huge and seemingly permanent loop known as the Atlantic Meridional Overturning Circulation (AMOC).

Ocean's heart is slowing down - and it will affect the entire planet's circulation Live Science - March 17, 2025
Melting ice could weaken Earth's strongest ocean current 20% by 2050. The influx of cold meltwater could slow the Antarctic Circumpolar Current by up to 20% by 2050. The slowdown could affect ocean temperatures, sea level rise and Antarctica's ecosystem. The Antarctic Circumpolar Current, which swirls clockwise around Antarctica, transports around a billion liters (264 million gallons) of water per second. It keeps warmer water away from the Antarctic Ice Sheet and connects the Atlantic, Pacific, Indian and Southern oceans, providing a pathway for heat exchange between these bodies of water.
