North Atlantic 'cold blob' suggests weakening of key ocean current AMOC
By
Carolyn Gramling
Summary
A patch of ocean south of Greenland and Iceland, known as the 'cold blob,' has cooled by about 1°C since the 19th century while the rest of Earth's oceans warm. Scientists attribute this anomaly to a potential weakening of the Atlantic Meridional Overturning Circulation (AMOC), a major ocean current system that regulates global climate. The research, published in Geophysical Research Letters, suggests the AMOC may be at its weakest point in over a millennium, with significant implications for global weather patterns, sea levels, and climate stability.

· 3 pulledA patch of ocean just south of Greenland and Iceland has gotten colder even as the rest of Earth's oceans have warmed.
Scientists now think they know why: The Atlantic Meridional Overturning Circulation, or AMOC, may be weakening.
The AMOC may be at its weakest point in over a millennium.
