Extended Data Fig. 7

a, The stacked normalized CB-δ15N record in relation to the b, Atlantic Meridional Mode index based on Chiang and Vimont, 20042. The Atlantic Multidecadal Oscillation is superimposed to show interrelations. Positive AMM states are indicated in grey and correspond to higher north-equatorial SST and easterly wind stress whereas negative AMM states are indicated in light blue and correspond to lower north–equatorial SST and higher easterly wind stress.
