Columbia Business School Professor Gernot Wagner spoke with MIT Technology Review senior editor James Temple about Project Stardust, the controversial startup seeking to cool the planet by releasing reflective particles into the atmosphere. Wagner emphasized that even small-scale geoengineering efforts require enormous resources, global coordination, and years of scientific validation. He cautioned that the financial, environmental, and geopolitical risks remain significant—and that such interventions cannot substitute for deep emissions reductions. Wagner noted that any experimentation must be guided by international governance to prevent unilateral climate actions with global consequences.
