In this tutorial we will explore a variety of strategies for sequestering carbon from the atmosphere, including geologic storage, stimulating biospheric growth, enhanced mineral weathering, soil carbon accumulation, biomass burial, and others. Our focus is both the science and technology that enable them to work, as well as their potential biogeochemical ramifications for Earth's global systems if pursued at scale. The class is structured as a tutorial, in which small groups of students meet individually with the instructor, and topics are presented by the students. Each student will write papers, give presentations, and lead discussions on 3 topics throughout the term. Course is limited to 12 undergraduate participants, who will be selected at the start of the term based on background, interests, and willingness to commit to the entire term. Fulfills the Institute scientific writing requirement. Offered 2026-27.
