Extended Data Figure 8

a, Black line, global and annual mean SSTs during the PETM, from experiment R07sm_Corg. Yellow circles, annual mean SST values at Site 401 in the model, at the times from PETM onset onwards that correspond to the δ11B-derived pH data points (see Fig. 3b). Blue and orange circles, δ18O- and Mg/Ca-derived SST estimates, respectively. b, Model-projected spatial pattern of annual mean SSTs at time 0. The star shows the location of Site 401. cf, Model-projected spatial patterns of the annual mean SST anomaly compared with time 0, for the time points shown in a.
