| | | The Atlantic meridional overturning circulation (AMOC)a system of ocean currents in the North Atlantichas a major impact on climate, yet its evolution during the industrial era is poorly known owing to a lack of direct current measurements. Here we provide evidence for a weakening of the AMOC by about 3?±?1 sverdrups (around 15 per cent) since the mid-twentieth century. This weakening is revealed by a characteristic spatial and seasonal sea-surface temperature fingerprintconsisting of a pattern of coolin... | ||
