The Atlantic Meridional Overturning Circulation (AMOC), one of
Earth’s major ocean circulation systems, redistributes heat on our planet and has a major impact on climate. Its past and future strength are therefore of major interest, but the system is not easily measured. In my presentation I will present a consistent picture of the evolution of the AMOC over different time scales and from different sources: From the about 15 years of direct continuous observational data, over reanalysis products and ship measurements to temperature and ocean sediment proxy data. The overview shows that while the AMOC displays a large amount of natural variability over the different time scales, its behaviour over the last one to two hundred years is unprecedented compared to the last 1,600 years and it is fairly certain that the AMOC over the last decades has been weaker than ever before in that time period.
