Boulder as a Vanguard Climate City with Jonathan Koehn
In this episode, we sit down with Jonathan Koehn, Boulder’s Director of Climate Initiatives, to unpack what it really takes to build street-level climate resilience. Moving past high-level emissions targets, Jonathan explains how Boulder is operationalizing its restructured climate tax to fund neighborhood microgrids, protect vulnerable communities first, and help residents execute property-level wildfire defense. We dive into the practical realities of deep adaptation and discuss how hyper-local initiatives like *Cool Boulder* turn climate anxiety into agency right in our own backyards.

From Bees to Biodiversity with Noah Wilson-Rich
In this episode we sit down with evolutionary biologist and serial entrepreneur Dr. Noah Wilson-Rich to discuss the critical transition from the "Save the Bees" movement to data-driven ecological restoration. As the founder of The Biodiversity Lab, Best Bees, and the non-profit Urban Bee Lab, Noah leverages "nature-tech"—including AI hive sensors and honey environmental DNA (eDNA) forensic tracking—to transform urban spaces from gray to green. We explore how his teams collaborate with institutions like NASA, MIT, and Harvard to track urban pollinator health, map local plant DNA, and help real estate developers and corporate leaders implement measurable biodiversity strategies that support both global food systems and business resilience.

Carbon Casting with Barclay Rogers
In this episode we sit down with Barclay Rogers, CEO of carbon-removal startup Graphyte, following the breaking news of their massive 60,000-ton, 10-year carbon removal agreement with JPMorganChase. Barclay breaks down how his company bypassed the massive energy demands and costs of popular Direct Air Capture (DAC) systems using a technique called Carbon Casting—and how cleaning up forest floors to prevent Western wildfires became the ultimate commercial selling point for major corporate buyers.

Climate Capital with Tom Chi
In this episode, Tom Chi—founding partner of At One Ventures and former Head of Product Experience at Google X, where he led the development of Google Glass and self-driving cars—discusses the core insights of his book, *Climate Capital: Investing in the Tools for a Regenerative Future*. Leveraging his extensive background as a physicist and designer, Chi challenges traditional economic models by framing economics as a practical design discipline that must align with the Earth's physical realities rather than theoretical pseudoscience. He moves past the polarizing extremes of blind tech-optimism and immobilizing climate doomism, offering a grounded, evidence-based toolkit that uses nature's highly efficient ecological systems as the ultimate blueprint. Ultimately, Chi outlines tangible, empoweringly realistic strategies that venture capitalists, sophisticated individual investors, pragmatic policy wonks, and environmental activists can deploy together to radically reinvent our industrial economy and ensure humanity becomes a net positive to nature.

Protest with Annie Marie Leonard and André Carothers
What do clean air, weekends off, and the freedom to marry whom you love have in common? They were all won through the power of peaceful protest. In this episode, we sit down with legendary activists Annie Marie Leonard (former Executive Director of Greenpeace USA) and André Carothers to discuss their powerful new book, *Protest: Respect It Defend It Use It*. Far from a standard how-to manual, this book is a sweeping, visual celebration of over 40 iconic global campaigns and the collective action that shaped our modern world. Together, we explore the incredible history of public dissent—featuring insights from guest essayists like Jane Fonda and Dolores Huerta—while confronting a chilling modern reality: the rapid rise of anti-protest laws and corporate SLAPP suits designed to silence everyday citizens. Tune in for an inspiring, urgent conversation about why defending our right to speak out is more critical now than ever, and how you can help protect the ultimate cornerstone of democracy.

Understanding Colorado's Snow Drought with Noah Molotch
Colorado is currently facing one of its most warm and dry winters on record, with snowpacks hitting historical lows and March heatwaves shattering 500-year records. In this episode, we sit down with Noah Molotch, Professor of Geography at CU Boulder, Research Scientist at NASA’s Jet Propulsion Laboratory, and a leading expert in snow hydrology, to make sense of this changing landscape. As Colorado faces record-shattering heat and historic snow lows, Noah joins us to break down the physics behind and implications of our changing landscape and climate.

Hydrogen Powered Data Centers with Yuval Bachar
In this episode, tech visionary and ECL CEO Yuval Bachar joins the conversation to unveil how hydrogen is solving the massive power and sustainability crisis currently facing the AI industry. Drawing on his leadership experience at Microsoft and Facebook, Bachar explains how ECL is moving beyond the traditional electrical grid to deploy modular, off-grid data centers that run entirely on hydrogen fuel cells, effectively eliminating carbon emissions and the need for external water cooling. The discussion dives into the radical efficiency of 3D-printed facility "blocks" that can be deployed in just months rather than years, the strategic importance of their new one-gigawatt site in Texas, and why Bachar believes that integrating localized energy generation is the only way to support the "unprecedented demand" of 100-kilowatt server racks without breaking the planet's infrastructure.
