Science Daily  August 5, 2021 The Atlantic Meridional Overturning Circulation, or AMOC, transports warm water masses from the tropics northward at the ocean surface and cold water southward at the ocean bottom. It influences weather systems worldwide. A potential collapse of this ocean current system could have severe consequences. An international team of researchers (Germany, UK) have developed a robust and general early-warning indicator for forthcoming critical transitions. Significant early-warning signals are found in eight independent AMOC indices, based on observational sea-surface temperature and salinity data from across the Atlantic Ocean basin. The findings support the assessment that the AMOC […]
