→Quantitative paleoclimate models
Quantitative paleoclimate models often produce unique solutions to the paleoclimatic interpretation of geologic and paleontologic data.

A quantitative community climate model (CCM<sub>1</sub>) at the National Center for Atmospheric Research was used by Amoco Production Research to investigate possible causes of Late Devonian extinctions.
