As climate impacts mount, pressure is building on policymakers to find ways to alleviate the crisis. One controversial option being explored is geoengineering - direct human interventions to cool the planet. But can we safely and effectively implement these large-scale climate remedies?

 Bryony Worthington sits down with Kelly Wanser, Executive Director of the nonprofit SilverLining, which conducted early-stage experiments to improve the reflectivity of clouds in an experiment earlier this year. They discuss the different climate interventions being researched, the scientific and political challenges, and the critical need for robust evidence and governance to navigate these uncharted waters. From cloud brightening experiments to stratospheric aerosol injection, this conversation explores the potential upsides and major risks involved in intervening in the Earth's climate system.
