How To Prevent Weapons of Mass Destruction in a Changing Geopolitical and Military Landscape | Global Catastrophic Risks

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, including weapons of mass destruction, the topic of this episode. You can find the report at globalchallenges.org/gcr-2026. Wilfred Wan is director of the Weapons of Mass Destruction Programme at the Stockholm International Peace Research Institute (SIPRI). Michael Wernstedt is acting head of Common Security at the Global Challenges Foundation. We kick off by discussing how geopolitical and military trends are increasing the risks surrounding weapons of mass destruction, before turning to a longer conversation about how to strengthen international cooperation and global governance to prevent the use of WMDs—and the catastrophe that would entail.
