•We present water isotope-enabled early Eocene simulations with multiple CO2 levels.•Model matches early Eocene and PETM δ18Oc data with RMSE approaching data error.•Eocene δ18Ow varies with hydrological cycle and ocean circulation changes.•A stronger ocean ventilation mixes water masses and increas...
