Today's episode is produced in partnership with the Global Challenges Foundation. The foundation is dedicated to raising awareness of global catastrophic risks and strengthening global governance to address them. The Global Challenges Foundation's 2026 Global Catastrophic Risks report outlines five of the biggest risks facing humanity today -- and how to stop them. You can find the report at globalchallenges.org/gcr-2026.

This is the fifth episode of this series, which has included episodes on specific risks like nuclear weapons, ecological collapse, catastrophic climate change — and even near-Earth asteroids. In today's episode, I am joined by the former prime minister of Sweden, Stefan Löfven, and Jens Orback, a strategic advisor to the Global Challenges Foundation, for a wide-ranging conversation about how we can better reform our politics and diplomacy to confront global catastrophic risks.

Managing global catastrophic risks requires systems of global governance, and in this episode we discuss how we can build our common defense against these challenges.
