Sep 15, 2026 · 34m
Summary
Host Ben Bradford interviews Alex Bell, head of the Bulletin of the Atomic Scientists, to discuss the Doomsday Clock’s record-low setting of 85 seconds to midnight. They explore the clock’s history, the expiration of US-Russia arms control treaties, and emerging threats like climate change and "mirror life." Bell argues that the primary risk is the erosion of diplomatic structures and shared facts, emphasizing that public pressure and diplomacy remain the only viable paths to averting catastrophe.
