90 Seconds to Midnight

The Bulletin of Atomic Scientists' have set this year's clock at 90 seconds to midnight — the closest to midnight it has ever been. Why is the clock so close to midnight and how do we come back from the brink? To answer these questions, Tom Collina talks with Dr. Rachel Bronson, President and CEO of the Bulletin of Atomic Scientists. On Early Warning, Angela Kellett sits down with Lilly Adams, senior outreach coordinator at the Union of Concerned Scientists. They discuss reports that officers who worked in a nuclear missile base have been diagnosed with blood cancer and how nuclear weapons have a long history of negative impacts on people.
