Abstract The Paleocene‐Eocene Thermal Maximum (PETM, ∼56 million years ago) is among the best‐studied climatic warming events in Earth history and often compared to projected anthropogenic climate change. PETM characterized by a rapid negative carbon isotope excursion global temperature increase of 4–5°C, accompanied changes spatial patterns evaporation precipitation hydrologic cycle. Recent model reconstructions suggest regionally complex non‐linear response one important aspect hydrology: enhanced moisture flux from low‐latitude ocean. In this study, we use elemental stable geochemistry surface‐dwelling planktic foraminifera Atlantic deep‐sea sedimentary record (IODP Site 1258) quantify sea‐surface (SST) salinity. Foraminiferal Mg/Ca δ 18 O values are interpreted with Bayesian forward proxy system reconstruct how SST salinity changed over at site. These then recent simulations Eocene warming. Our indicate °C warming, excellent agreement estimates other tropical locations modeled warmth. regional change not as straightforward, demonstrating slight decrease extreme p CO 2 forcing (a reversal sense under moderate forcing) both reconstructions. cause unclear but may relate increased South American continental runoff or shifts Inter‐Tropical Convergence Zone.
