Extended Data Fig. 4

B. We compare the relative changes that are recorded G. bulloides δ18O to a Northern Hemisphere Temperature anomaly for the 1900–2000 period and see a good agreement between temperature trends recorded in these records (Jones et al., 2013). C. We also compared G. bulloides δ18O to in situ sea surface temperature (SST) measurements made in the Santa Barbara Basin (SBB; 1955-Present; Shore Stations Program) and see an excellent agreements between sea surface temperature and the δ18O recorded in our G. bulloides shells.
