The book discusses the ideas and creates a framework for building toward a theory of paleoclimate. Using the rich and mounting array of observat ional evidence of climatic changes from geology, geochemistry, and paleo ntology, Saltzman offers a dynamical approach to the theory of paleoclim ate evolution and an expanded theory of climate. Saltzman was a distinqu ished authority on dynamical meteorology. This book provides a comprehen sive framework based on dynamical system ideas for a theory of climate a nd paleoclimatic evolution which is intended for graduate students and r esearch workers in paleoclimatology, earth system studies, and global ch ange research. The book includes an extensive bibliography of geological and physical/dynamical references.
