Earth System Science Research

Research in the Department of Earth System Science at the University of California, Irvine focuses on how the atmosphere, land and oceans interact as a system and how the Earth will change over a human lifetime. ESS faculty research interests vary widely from climate, atmospheric chemistry, and biogeochemistry to oceanography and hydrology. The department ranks among the top U.S. universities for the impact of its publications in the geosciences. In addition to their research, faculty work to inform and educate policy makers and the community at large on a range of issues affecting the environment and quality of life.
