A Crucial Atlantic Current Is Weakening and Weather Could Change Worldwide

New ocean monitoring data shows a major part of the Atlantic Meridional Overturning Circulation has been steadily weakening for about 20 years.

Researchers say this is strong direct evidence that the AMOC is slowing down, not just a short-term fluctuation.

A weaker AMOC could alter storms, rainfall, winter weather, and sea levels across the North Atlantic and beyond.

The findings improve early warning for major climate shifts and were reported by researchers including the University of Miami and NOAA in Science Advances.
