Evolution of the Earth System
Evolution of the Earth System
Session ID#: 123678
Session Description:
Earth has evolved as a coupled system, with rich interactions between biology, geology, chemistry, and climate. A wide array of geophysical, 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 observational, experimental, or theoretical approaches, for any period in Earth history. Topics will include evolution of major (bio)geochemical cycles (C, O, N), reconstructions of nutrient cycling and productivity, climate change and stability, geochemical controls on climate, changes in atmosphere and ocean oxygen at a variety of scales, tectonic evolution, the co-evolution of life and the environment and many others.
