European governments weigh AMOC collapse contingency as Atlantic current weakens

European governments are increasingly treating a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC) as a credible scenario, moving from distant risk to active contingency planning. The current system, which transports warm tropical waters to the North Atlantic, could weaken significantly due to global warming, with extreme outcomes including much colder European winters, droughts, stronger storms, and sea-level rise. The report, based on Politico, indicates a shift in official risk assessment, though the timeline and probability of collapse remain highly uncertain.
