Modifying Earth’s climate is one of the largest proposed activities in history. Designing, constructing, and managing such a large endeavor will require engineering. We explore engineering questions from both a systems and deployment perspective and how they can inform the science of SRM and CDR climate engineering.
Ben Kravitz is a climate scientist in the Atmospheric Sciences and Global Change Division at the U.S. Department of Energy's Pacific Northwest National Laboratory. His research involves using climate models to understand climate response to perturbations on a variety of timescales. Ben's focus is on climate model simulations of geoengineering. He is the coordinator of the Geoengineering Model Intercomparison Project (GeoMIP), an international effort to understand the robust responses of climate models to standardized scenarios of geoengineering.
David Keith has worked near the interface between climate science, energy technology, and public policy for twenty-five years. He took first prize in Canada's national physics prize exam, won MIT's prize for excellence in experimental physics, and was one of TIME magazine's Heroes of the Environment. David is Professor of Applied Physics in Harvard’s School of Engineering and Applied Sciences and Professor of Public Policy in the Harvard Kennedy School, and founder at Carbon Engineering, a company developing technology to capture of CO2 from ambient air to make carbon-neutral hydrocarbon fuels. Best known for work on the science, technology, and public policy of solar geoengineering, David is leading the development of an interfaculty research initiative on solar geoengineering at Harvard. David’s work has ranged from the climatic impacts of large-scale wind power to an early critique of the prospects for hydrogen fuel. David’s hardware engineering projects include the first interferometer for atoms, a high-accuracy infrared spectrometer for NASA's ER-2, and currently, development of CO2 capture pilot plants for Carbon Engineering. David teaches courses on Science and Technology Policy and on Energy and Environmental Systems where he has reached students worldwide with an online edX course. He has writing for the public with A case for climate engineering from MIT Press. Based in Cambridge, David spends about a third of his time in Canmore Alberta.
