Physics-based early warning signal shows that AMOC is on tipping course

René M. Van Westen, Michael Kliphuis, and Henk A. Dijkstraa, Science Advances: “The European climate is greatly affected … under the AMOC collapse. Note that the corresponding changes occur within [a 100 year period] and under a very small change in surface freshwater forcing. The yearly averaged atmospheric surface temperature trend exceeds 1°C per decade over a broad region in northwestern Europe, and for several European cities, temperatures are found to drop by 5° to 15°C ….”
