David Keith reviews the science and technology of solar geoengineering, addressing the following Q’s: how effective could it be in reducing climate risks? What new risks does it entail? What is uncertain? And, finally, how could uncertainty be reduced to a substantial research program? He presents a case for integrating solar geoengineering into a 4D climate policy that includes emissions cuts, carbon removal, and adaptation.

David Keith has worked near the interface between climate science, energy technology, and public policy since ’91. 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 at the Harvard School of Engineering and Applied Sciences and Professor of Public Policy at the Harvard Kennedy School, and founder of Carbon Engineering, a Canadian company developing technology to capture CO 2 from ambient air to make carbon-neutral hydrocarbon fuels. Best known for his work on the science, technology, and public policy of solar geoengineering, David led the development of Harvard’s Solar Geoengineering Research Program, a Harvard-wide interfaculty research initiative. His 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 work includes the first interferometer for atoms, a high-accuracy infrared spectrometer for NASA’s ER-2, the development of Carbon Engineering’s air contactor and overall process design, and the development of a stratospheric propelled balloon experiment for solar geoengineering. He teaches science and technology policy, climate science, and solar geoengineering. David is the author of over 200 academic publications with a total citation count of over 13,000. He has written for the public in op-eds and A Case for Climate Engineering.

This infographic and animation tracks cumulative natural gas wells drilled in Pennsylvania from January 2005 to April 2012, highlighting the state's transition from conventional vertical to horizontal drilling.

Horizontal wells, primarily in the Marcellus, Utica, and Geneseo/Burket shale formations, increased significantly. Concurrently, less productive vertical wells declined, resulting in an overall decrease in new well counts.

A massive influx of clean energy investments is poised to transform the American economy during this decade. Opportunities abound to take advantage of new climate incentives. If we get this right, the U.S. could be on track to reach 80% clean power by 2030, leading to deep decarbonization across other sectors including transportation, buildings and manufacturing. Nevertheless, success is far from guaranteed without widespread action from the grassroots to the canopy. What did it take to pass a historic $370 billion climate deal in Congress? How can American households and businesses take full advantage of it? What does effective, equitable implementation look like? Join award-winning author, political scientist, and climate expert Dr. Leah Stokes for a deep dive on clean energy policy and the tools we have to realize our electric future in this decade and beyond.

Leah Stokes, Ph.D., one of the nation’s most influential leading experts and “engaged scholars" in climate and energy policy, is the author of the award-winning book Short Circuiting Policy, which examines the role of utilities in undermining regulation and promoting climate denial. Trained at MIT, Columbia, and the University of Toronto, Stokes’ widely read and cited work has been published in top scholarly journals, as well as the New York Times, Washington Post, and other popular media outlets. She is the Anton Vonk Associate Professor of Environmental Politics at the University of California, Santa Barbara, a senior policy consultant at Rewiring America, and co-host of the popular climate podcast “A Matter of Degrees.”
