The concept of solar geoengineering—blocking the sun’s radiation to slow Earth’s warming—is no longer just the realm of science fiction. In 2023, the U.S. government and the UN released reports on the topic. Whether or not solar geoengineering can save the world is up for debate, and Tony Harding, an assistant professor in the School of Public Policy, is contributing to the conversation.
Harding is an alumnus of the School of Economics and returned to Georgia Tech after a postdoc at Harvard University. He studies the impact of innovative technology on climate change policy and governance, focusing on solar geoengineering. In the eight years he’s been researching it, Harding said it’s the scale of the conversation that’s changed the most: not what the researchers are speaking about, but who they’re speaking to.
