A controversial tactic against climate change


David Keith has a tool for fighting climate change, and a big challenge: convincing the rest of the world to use it. Speaking to science writers gathered in State College, Pa. on Oct. 28, Keith, a professor of applied physics and public policy at Harvard University, said he understands why some are apprehensive about his approach.

“This topic is controversial,” Keith said, “and it should be.”

Keith spoke during the annual New Horizons in Science briefing presented by the Council for the Advancement of Science Writing as part of ScienceWriters2019.
