As the impacts of climate change grow more severe and global decarbonization goals creep farther out of reach, conversations about direct intervention in the planet’s atmosphere are growing more serious. As geoengineering moves from science fiction to scientific proposals, policymakers and the public must answer whether, when, how, and how much to alter the Earth’s atmosphere—and who gets to decide.

Speakers:

  • David Keith, Founding Faculty Director, Climate Systems Engineering initiative
  • Sue Biniaz, Distinguished Fellow, Institute for Climate and Sustainable Growth
  • George David Banks, President and CEO, American Council for Capital Formation
  • Patrick Taylor Smith, Associate Principal, Principia Advisory; Resident Fellow, Stockdale Center for Ethical Leadership, United States Naval Academy

This event took place at Aspen Ideas: Climate 2026.
