Scientists Track Ocean Current Shift That Could Redraw Global Climate Maps

New data from an expanded network of deep-ocean monitoring instruments has confirmed a significant slowdown in the Atlantic Meridional Overturning Circulation — the system of ocean currents fundamental to regulating temperatures across Europe.

Data from 847 monitoring points shows a reduction in circulation strength of approximately 18 percent compared with 1990s observations.

“A sustained slowdown of this magnitude would produce measurable cooling in Western Europe, disruption to monsoon systems, and increased storm intensity along the US Atlantic coast,” said the principal investigator.
