Atlantic Ocean Currents Weaken, Risking Collapse by Mid-Century
Atlantic Ocean Currents Weaken, Risking Collapse by Mid-Century
US · Published Apr 17, 2026
The Atlantic Meridional Overturning Circulation (AMOC), a vital ocean current system, is showing signs of significant weakening due to human-induced global warming.
Studies suggest the AMOC could collapse as early as the next decade, leading to dramatic cooling in Europe, accelerated sea level rise, and disrupted weather patterns.
Reducing greenhouse gas emissions is crucial to slow down global warming and prevent further disruption of the AMOC, requiring international cooperation and policy changes.
AMOC weakening: a concerning trend emerges
Recent studies have brought to light a concerning trend regarding the Atlantic Meridional Overturning Circulation (AMOC), a critical system of ocean currents in the Atlantic Ocean. Functioning much like a conveyor belt, this system is responsible for transporting heat, salt, and freshwater and is now exhibiting signs of considerable weakening. This decline in the AMOC's strength is largely attributed to human-induced global warming, which disrupts the delicate equilibrium of heat and salinity within the ocean. Two recent studies have presented alarming evidence of this weakening, suggesting that the AMOC could potentially collapse as early as the next decade.
