Understanding global environmental issues such as global warming, stratospheric ozone depletion, and worldwide air pollution requires the cooperation of scientists across many fields. Global change is projected to accelerate through the 21st century and will impact the ecosystems that preserve the habitability of the planet. The Department of Earth System Science focuses on the atmosphere, land, and oceans, how these interact as a system, and how the Earth will change over a human lifetime. Earth System Science (ESS) is inherently interdisciplinary in scope, linking oceanography, atmospheric and terrestrial sciences, climatology, hydrology, biology, physics, and chemistry to understand the environment. ESS faculty includes chemists, biologists, ecologists, physicists, hydrologists, geologists, meteorologists, engineers, applied mathematicians, and oceanographers. The wide-ranging expertise of ESS faculty and teaching assistants allows students to learn valuable scientific skills in the classroom, laboratory, and field experiences.
What Sets Us Apart?
- The Earth System Science Ph.D. program is fully-funded, including tuition and fees, in addition to a yearly stipend.
- We aim to help our students develop a mechanistic understanding of the Earth and gain the conceptual and analytical tools needed for research in this rapidly growing field.
Normative Time to Degree
- Undergraduate courses in calculus, linear algebra, and differential equations.
- One-year sequences of undergraduate physics (calculus based) and chemistry.
Students with undergraduate degrees in other fields are invited to apply, provided they meet the general background standards listed above. Undergraduate courses in atmospheric science, oceanography, and biology are useful but not required as part of the undergraduate background. Students who are unsure if their academic background or training matches the profile described above are encouraged to contact potential advisors.

Eligibilty for Application Fee Waivers
Does the program have scholarships or fellowships available?
Yes, all admitted students (including international students) are fully-funded. This includes a moving allowance, an annual stipend of $32,865, tuition and fees, and UCI health insurance.
Does UCI have on-campus housing for graduate students?
Yes, students who are admitted to the Earth System Science Ph.D. program are eligible for a guaranteed offer of on-campus housing. To be eligible for this guarantee students must respond to Housing prior to their deadline at the beginning of May. Please refer to the Graduate & Family Housing website for specific information.

The tuition, fees, and charges posted to your billing statement or account are estimates based on currently approved amounts. These figures may not be final. Actual tuition, fees, and charges are subject to change by the Regents of the University of California and could be affected by increases or reductions in State funding, or other developments. Accordingly, final approved levels (and thus your final balance due) may differ from the amounts shown.
* The Document Fee provides lifetime access to official transcripts and academic verifications without a fee for in-person pickup or delivery by USPS. In addition, there is no fee for mailing the initial diploma. Effective Fall 2018, new undergraduate, professional, and graduate students are assessed the one-time document fee. Eligible students are able to use financial aid to cover the Document Fee.
