From: δ18O and SST signal decomposition and dynamic of the Pliocene-Pleistocene climate system: new insights on orbital nonlinear behavior vs. long-term trend

Comparison over time of the long-term trend components of δ18O and the a pCO2 and b SST proxies. Composite atmospheric boron-based pCO2 proxy from ODP Sites 668B-999A (Hönisch et al. 2009; Bartoli et al. 2011), atmospheric alkenone-based pCO2 and SST proxies from ODP Site 999A (Seki et al. 2010), alkenone-based SST proxy from ODP Site 846 (Herbert et al. 2010b), EPICA pCO2 record (Berger et al. 2016), δ13C-based pCO2 proxy (Lisiecki 2010b), LR04 δ18O stack (Lisiecki and Raymo 2005b), boron-based pCO2 proxy from ODP Site 999 and global ΔSST stack (Martinez-Boti et al. 2015). The horizontal lines are the Plio-Pleistocene average of pCO2 alkenone (ODP Site 999A) and the standardized mean of the SST. All records are plotted on their own age scale
