Stefan Rahmstorf – Evidence for a weakening Atlantic Ocean overturning circulation

Possible changes in Atlantic meridional overturning circulation (AMOC), sometimes referred to as the Gulf Stream System, provide a key source of uncertainty regarding future climate change. Maps of temperature trends over the twentieth century show a conspicuous region of cooling in the northern Atlantic, as well as excessive warming along the North American coast. Both combined are a ‘fingerprint’ characteristic of an AMOC slow down by about 15%, unique in the past millennium or more. A number of studies of... View Article
