FOS4 | Frontiers of Science: Climate & Us with David Helfand, Professor, Department of Astronomy and Ivana N. Hughes, Director of Frontiers of Science, Columbia University

Frontiers of Science is a one-semester course that integrates modern science into Columbia's Core Curriculum. Its goal is to challenge students to think about the world around them, and the ways in which science can help us answer questions about nature and ourselves. The course focuses on the commonalities of the scientific approach to inquiry as exemplified by four areas of active research and discovery.

FOS4 - Climate & Us: The Earth’s temperature is determined by a balance between incoming energy and outgoing energy, which is affected by many factors, including sunspots, astronomical cycles, and greenhouse gasses. In this course, we compare recent climate conditions with a vast historical record that goes back thousands, even millions, of years. We also investigate the role of feedback loops and why they make climate modeling particularly challenging.
