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... |

guest post by Jan Galkowski 1. How Heat Flows and Why It Matters Is there something missing in the recent climate temperature record? Heat is most often experienced as energy density, related to temperature. While technically temperature is only meaningful for a body in thermal equilibrium, temperature is the operational definition of heat content, both... |
