  • Can Technology Fix the Climate? with Adam Dorr

    Can Technology Fix the Climate? with Adam Dorr
    May 28 2026
    In this Climate Chat episode, host Dan Miller interviews author and RethinkX's Director of Research, Adam Dorr, about his two books, Brighter, and The Degrowth Delusion. RethinkX is a think tank that focuses on disruptive technologies including renewable energy and precision fermentation. Adam argues renewable energy will dominate future energy supply and that "degrowth" will not provide us with the resources to fight climate change. Adam Dorr is an environmental social scientist, technology theorist, and author. As Director of Research at RethinkX, he leads analysis and forecasting of technology-driven disruptions in energy, transportation, food, and labor. His work argues that the converging disruptions of the 21st century will not only solve our most pressing environmental challenges but also open the door to unprecedented human flourishing. Adam's work makes a data-driven case for optimism about our shared future.

  • Throwing Shade at Global Warming: Risks & Reality of Planetary Sunshades with Ross Centers

    Throwing Shade at Global Warming: Risks & Reality of Planetary Sunshades with Ross Centers
    May 23 2026
    In this Climate Chat episode, host Dan Miller interviews Planetary Sunshade Institute's Board Member and former Executive Director, Ross Centers, on the science, risks, and reality of using giant space-based sunshades located between the Sun and the Earth to reduce global warming. Ross Centers is an American planetary geologist, space entrepreneur, and climate advocate. He is the Co-Founder and CEO of Ethos Space, a lunar infrastructure startup. Based in Los Angeles, California, Centers has positioned himself at the intersection of commercial space resource utilization (SRU) and space-based climate mitigation technologies. By leveraging a deep technical background in space architecture and resources, his career focuses on establishing the physical infrastructure required to sustain an off-world economy while simultaneously building tools to stabilize Earth's climate. Centers developed his expertise in aerospace and geology at the Colorado School of Mines, where he earned a Master’s degree in Space Resources.
