PP41D:
Evolution of the Earth System Posters


Submit an Abstract to this Session


Session ID#: 48428

Session Description:
Earth has evolved as a coupled system, with rich interactions between biology, geology, chemistry and climate. A wide array of geochemical and climatic states have existed through a continuously habitable period of at least 4 billion years. Understanding this evolution is necessarily an interdisciplinary problem. We welcome contributions which chart or explain this evolution, with either observational or theoretical approaches, for any period in Earth history. Topics will include evolution of major geochemical cycles (C, O, N), major climatic events and the co-evolution of life and the environment.
