# Atlantic current collapse hinges on speed of CO2 rise

New research indicates the fate of the Atlantic Meridional Overturning Circulation (AMOC) depends on how quickly carbon dioxide levels rise, not just the final warming threshold. A rapid surge in CO2 could trigger an abrupt collapse of this crucial ocean current system. Such a collapse would cause severe climate disruption across the globe, making the rate of emission cuts critical.
