From "How We Survive": How to Dim the Sun

This episode explores the emerging reality of solar geoengineering, traveling to a site in Northern California where entrepreneurs are testing sulfur-filled balloons to dim the sun. It examines how a concept once confined to sci-fi is now being actively pursued as a climate intervention. The show also presents the scientific debate: could this technique buy us time against catastrophic tipping points, or would it unleash unpredictable cascading consequences? The episode balances the urgency of climate action with the risks of large-scale planetary engineering.
