Columbia Business School’s Professor Gernot Wagner spoke with POLITICO reporters Corbin Hiar and Karl Mathiesen about the global cooling startup Stardust, which recently raised $60 million to test sun-reflecting aerosol technology. Professor Wagner discussed the scientific, regulatory, and ethical complexities surrounding geoengineering efforts, emphasizing the need for rigorous oversight as private companies enter a space traditionally dominated by research institutions. He noted that while technological approaches to solar radiation management may offer potential climate benefits, they also carry significant geopolitical and environmental risks, underscoring themes explored in his book Geoengineering: The Gamble.
