Title – Climate Model Simulations of Geoengineering

Abstract –  Geoengineering describes a set of technologies to temporarily, deliberately modify the climate, preventing some of the worst consequences of climate change.  Although these ideas, like mimicking the cooling from large volcanic eruptions or brightening low clouds over the oceans, would likely have substantial benefits, they also come with profound risks.  Because nobody has done geoengineering in the real world, most of our knowledge comes from climate models.  Here I will provide an overview of what we know about geoengineering from those models, how we know it, and what some of the major uncertainties are.

Bio – Dr. Ben Kravitz is an assistant professor in the Department of Earth and Atmospheric Sciences at Indiana University. He holds a B.A. in mathematics from Northwestern University, an M.S. in mathematics from Purdue University, and an M.S. and Ph.D. in atmospheric science from Rutgers University. He completed a postdoctoral research position at the Carnegie Institution for Science and another postdoctoral research position at Pacific Northwest National Laboratory, where he became a staff scientist in 2015. He joined the faculty at Indiana University in 2019, maintaining a joint appointment at Pacific Northwest National Laboratory. Dr. Kravitz is an international expert in climate model simulations of climate engineering. His current activities also include using engineering and mathematical techniques in climate models to better understand climate feedbacks, studying teleconnections in high latitude climate, and developing climate model emulators for use in Integrated Assessment Models.
