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. Global Challenges Foundation's 2026 Global Catastrophic Risks report outlines five of the biggest risks facing humanity today, including catastrophic climate change, the topic of this episode. You can find this report at globalchallenges.org/gcr-2026.

Two of the authors of the chapter on catastrophic climate change are my guests today. Manjana Milkoreit is a researcher of earth systems governance at the University of Oslo. Eva Mineur is head of climate and sustainability at Global Challenges Foundation.

We kick off by discussing what we mean by catastrophic climate change and examining examples of this phenomenon already underway around the world, before turning to a longer conversation about how to strengthen international cooperation and global governance to prevent catastrophic climate change—and the catastrophe it would entail.
