David Keith

Professor, Harvard & Founder, Carbon Engineering

David Keith has worked near the interface between climate science, energy technology, and public policy for 25 years. Best known for his work on the science, technology, and public policy of solar geoengineering, he led the development of Harvard’s Solar Geoengineering Research Program. 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.” Keith is a professor at the Harvard School of Engineering and Applied Sciences and Harvard Kennedy School, and is the founder of Carbon Engineering, a company developing technology to capture CO2 from ambient air.


More About David Keith

"There is growing scientific interest in solar geoengineering as a possible means of combating climate change in conjunction with emissions cuts. But by foregoing debate and research on these new technologies now, political leaders may actually increase the risks of their future misuse."

"Climate-change experts are researching ways to cool down the planet using geoengineering. How could spraying chemicals into the stratosphere help counteract global warming?"

"The seriousness of the risks posed by climate change demands that we examine all possible means of response, but how we do so makes all the difference."

"Models suggest solar geoengineering could reduce climate change and our independently assessed studies are vital to understanding its full potential."

"If all goes as planned, the Harvard team will be the first in the world to move solar geoengineering out of the lab and into the stratosphere, with a project called the Stratospheric Controlled Perturbation Experiment (SCoPEx). The first phase — a US$3-million test involving two flights of a steerable balloon 20 kilometres above the southwest United States — could launch as early as the first half of 2019."

"Harvard researchers want to see what adding calcium carbonate could do to the stratosphere."

"Solar geoengineering (SG) has the potential to restore average surface temperatures by increasing planetary albedo, but this could reduce precipitation. Thus, although SG might reduce globally aggregated risks, it may increase climate risks for some regions."
