Columbia Business School’s Professor Gernot Wagner spoke with Futurism reporter Victor Tangermann about Stardust, a global cooling startup aiming to use atmospheric aerosol injections to reflect sunlight and lower planetary temperatures. Professor Wagner discussed the scientific uncertainties and governance challenges surrounding private-sector geoengineering initiatives, emphasizing that deploying such technologies without comprehensive oversight could carry unintended climate and geopolitical consequences. He noted that while research into sun-reflecting methods is advancing rapidly, large-scale experimentation requires robust regulation, global cooperation, and transparent risk assessment.
