Overview
Earth System Science draws on chemistry, physics, biology, mathematics and applied sciences in an effort to understand the chemical, physical, biological and human influences on our planet. The major is ideal for students seeking a fundamental understanding of geosciences and the flexibility to pursue intensive study in other disciplines.
Fast Facts
- A majority of courses integrate a fieldwork component
- Tigers perform research with faculty who are active scholars
- Most Tigers who pursue graduate work receive full financial support

When You Graduate
Find Your Sustainable Future
Trinity graduates have a versatile, expansive background in both science and policy. They apply this to a wide range of postgraduate opportunities, such as graduate or professional studies in medical school, law school, education, and archaeological and museum studies.
“I love geology because it’s the story of how the earth was created—how it evolved. And at Trinity, we learned in the real world. We’d take trips to field sites in Colorado, the Guadalupe Mountains, and West Texas. All of the time you learn social skills, and you learn how to work as a team.”
“In every Trinity class we were expected to present and defend our ideas, whether it was through written papers or class presentations,” says Schwed. “That translates nicely into my collaborative work environment today where I constantly have to express my technical work and defend it.”
Through film, Scott Tinker ’82 and son Derek Tinker ’14 can show you a powerless world: one with no cell phones, electricity, or even running water.
But the Tinkers don’t dabble in fictional dystopia—this is real life for billions of people across the globe who still live in energy poverty.
