Never before in over 1000 years the Gulf Stream System (also known as the Atlantic Meridional Overturning Circulation AMOC), has been as weak as in the last decades. PIK researchers have determined evidence of the AMOC weakening with the help of 11 proxy data series (information gathered by so called climate archives like ocean sediments, corals etc): They have compiled 11 independent data series from the North Atlantic, almost all of them from deep-sea sediment cores. They all provide a consistent picture about the flow characteristics of the Gulf Stream System and its weakening in the past 70 years. The slowdown is likely related to man-made climate change.
