Millennium-scale evolution of the Atlantic Meridional Overturning Circulation (AMOC), 400 - 2020. SST-based AMOC reconstructions (light and dark blue) compared to various proxy reconstructions, including land and sea surface temperature reconstructions, sortable silt data, δ18O in benthic foraminifera, δ15N of deep-sea gorgonian corals, and relative abundance of Turborotalita quinqueloba. Since at least 400 AD relatively stable, the AMOC began to decline during the 19th Century which is evident in all proxy records. Around 1950 a phase of particularly rapid decline started that is found in several, largely independent proxies. A short-lived recovery is evident in the 1990s before a return to decline from the mid-2000s. Together these data consistently show that the modern AMOC slowdown is unprecedented in over a thousand years. Graphic: Levke Caesar
