- •
We simulate Eocene climate of western North America with a global climate model.
- •
Eocene temperature and moist enthalpy lapse rates differ from present-day.
- •
Eocene temperature and moist enthalpy vary non-linearly with increasing elevation.
- •
Proxies agree with simulations when Cordilleran elevation is prescribed to be 2–3 km.
- •
Model suggests foreland elevations are significantly lower than the Cordillera hinterland.
