Speleothem calcium carbonate oxygen isotope records (d18OCc) indicate that the collapse of the AMOC caused dramatic changes in the distribution and variability of the East Asian and Indian monsoon rainfall. However, the mechanisms linking changes in the intensity of the AMOC and Asian monsoon d18OCc are not fully understood. Part of the challenge arises from the fact that speleothem d18OCc depends on not only the d18O of precipitation but also temperature and kinetic isotope effects. Here we quantitatively deconvolve these parameters affecting d18OCc by applying three geochemical techniques in speleothems covering the penultimate glacial termination. Our data suggest that the weakening of the AMOC during meltwater pulse 2A caused substantial cooling in East Asia and a shortening of the summer monsoon season, whereas the collapse of the AMOC during meltwater pulse 2B (133,000 years ago) also caused a dramatic decrease in the intensity of the Indian summer monsoon. These results reveal that the different modes of the AMOC produced distinct impacts on the monsoon system. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Max Planck
