  • Does AMOC Collapse Depend on Rate of Warming? with René van Westen

    Does AMOC Collapse Depend on Rate of Warming? with René van Westen
    Aug 14 2026
    In this Climate Chat episode, we interview returning guest René van Westen on his latest Atlantic Meridional Overturning Circulation (AMOC) research that shows that AMOC collapse depends not on the amount of warming but rather the *rate* of warming. Dr. Westen is a postdoctoral researcher at Utrecht University in the Netherlands.

  • The Biology of Collapse with George Tsakraklides

    The Biology of Collapse with George Tsakraklides
    Aug 10 2026
    In this Climate Chat episode, we interview scientist, activist and author George Tsakraklides about his book, The Biology of Collapse. George Tsakraklides is an author, Substack writer, and interdisciplinary commentator with an educational background spanning molecular biology, chemistry, food sciences, and Earth sciences, alongside two decades of experience in corporate data analytics and marketing. He has authored numerous works of non-fiction, fiction, and poetry—including The Biology of Collapse: Lessons from Nature on Growth, Power, Extinction and Rebirth, Beyond the Petri Dish, The Unhappiness Machine, and Frankenpolitics. His core perspective draws direct parallels between natural biological systems and human socioeconomic structures. He heavily critiques endless economic growth as an unsustainable, terminal pathology, while frequently challenging mainstream political reform and the efficacy of traditional technological mitigation strategies.
