He has also been the advisor of many PhD students who have explored and expanded the frontiers of paleoclimate modeling.Īs a climate modeler, he studies very different climate contexts from “Snowball Earth” episodes (717-635 Ma) to more recent, and occasionally future, climate situations.The main research topics he focuses on are: He has been responsible for many French and European research projects on the Pleistocene, Cenozoic and Precambrian eras.

His initial degree is in physics and since 1992 he has specialized in climate modeling. Gilles Ramstein is a director of research at Laboratoire des Sciences du Climat et de l’Environnement (LSCE, France). This volume provides both an analytical understanding of each component using a hierarchy of models (from conceptual to very sophisticated 3D general circulation models) and a synthetic approach incorporating all of these components to explore the evolution of the Earth as a global system.Īs a whole this book provides the reader with a complete view of data reconstruction and modeling of the climate of the Earth from deep time to present day with even an excursion to include impacts on future climate. The chapters are based on understanding the processes driving the evolution of each component of the Earth system (atmosphere, ocean, ice). The second volume, entitled “Investigation into ancient climates,” focuses on building comprehensive models of past climate evolution. Different fields of geosciences such as: stratigraphy, magnetism, dendrochronology, sedimentology, are drawn from and proxy reconstructions from ice sheets, terrestrial (speleothems, lakes, and vegetation) and oceanic data, are used to reconstruct the ancient climates of the Earth. It describes the different geo-chronological technical methods used in paleoclimatology. The first volume is devoted to “Finding, dating and interpreting the evidence”.
