A: Earth System Science

If you are interested in the science of global environmental issues such as global warming, stratospheric ozone depletion, and worldwide air pollution, this is the college major for you.

The UCI Department of Earth System Science studies the atmosphere, land, and oceans, how these interact as a system, and how the Earth will change over a human lifetime. The major is an interdisciplinary field of study that combines oceanography, atmospheric science, meteorology, geography, geology, hydrology, and environmental science.
