Understanding how our planet works
Our goal is to understand, predict, and respond to human-caused and natural environmental change at local to global scales. Scientists in our Earth System Science department offer a strong graduate research program across a broad range of environmental and Earth science disciplines for students working toward a doctoral degree. Undergraduate and coterminal master's degrees are offered through the closely related and popular Earth Systems Program.
Degree Programs
Undergraduate
The Earth System Science department does not have an undergraduate program. However, many of its faculty teach in the popular, interdisciplinary Earth Systems Program, which offers a BS and co-terminal MS degree.
Graduate Program
Through its courses, seminars, and speaker series, ESS offers graduate students an opportunity to be part of an intellectual community with common or related interests and goals.
