The study of greenhouse climates in the earth's past leads to a greater understanding of the factors that influence today's climate. In this fully integrated volume, leading experts in paleoclimatology present cutting edge paleontological, geological, and theoretical research to assess intervals of global warmth. Coverage examines warm climate intervals during the Paleozoic, Mesozoic and Cenozoic from the same perspectives: oceanic and terrestrial, theoretical and observational. This approach illuminates the differences and, more importantly, the commonalities of warm climate intervals. The...
