Collapse of Atlantic circulation risks mass oceanic carbon release (nature.com)

• Disruption of AMOC weakens biological and solubility carbon pumps.
• Positive feedback loop: oceanic CO2 release accelerates global warming.
• Strategic risk to European coastal stability and critical infrastructure.

"New research indicates that a total collapse of the Atlantic Meridional Overturning Circulation (AMOC) would fundamentally alter oceanic carbon sequestration. By disrupting deep-water formation, the ocean would transition from a global carbon sink to a potential source of massive atmospheric CO2 release. This shift poses existential risks to European climate stability and threatens maritime infrastructure due to altered circulation patterns and sea-level variability."
