  • 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.

  • The Physics & Economics of Sea Level Rise with Robert Kopp

    The Physics & Economics of Sea Level Rise with Robert Kopp
    Jul 26 2026
    In this Climate Chat episode, host Dan Miller interviews climate scientist Dr. Robert Kopp about sea level rise predictions and the economic impacts of sea level rise. Robert Kopp is a climate scientist who serves at Rutgers University as a Distinguished Professor in the Department of Earth & Planetary Sciences. Professor Kopp’s research focuses on past and future sea-level change, the interactions between physical climate change and the economy, the use of climate risk information to inform decision-making, and the role of higher education in supporting societal climate risk management. He directs the Megalopolitan Coastal Transformation Hub, a Rutgers-led consortium that advances coastal climate adaptation and the scientific understanding of natural and human coastal climate dynamics. He is a founding principal investigator of the Climate Impact Lab, a multi-institutional collaboration advancing data-driven approaches to estimating the social and human costs of climate change. He is also co-lead for engagement and applications for the NASA Sea-Level Change Team. He was a lead author of the Intergovernmental Panel on Climate Change’s recent (2021) Sixth Assessment Report. He has previously served at Rutgers as Director of the Rutgers Institute of Earth, Ocean, and Atmospheric Sciences and as co-director of the University Office of Climate Action. Professor Kopp received his Ph.D. in Geobiology from the California Institute of Technology and his undergraduate degree in Geophysical Sciences from the University of Chicago. He is a fellow of the American Geophysical Union and the American Association for the Advancement of Science, and a 2024 Guggenheim Fellow.
