The Major

The purpose of the Earth Systems degree is to provide students with a holistic understanding of the Earth’s geosphere, biosphere, atmosphere, hydrosphere, and cryosphere, as well as the impact of human activities on these systems. The degree is suitable for students interested in the interface of earth science and related fields, and in issues related to the long-term management and sustainability of the planet.
