At the intersection of climate change, technology, and parenthood.
Climate Papa is a home for the climate dads, climate papas, and climate papis. The climate abbas, the climate babas, and climate tatas.
We're here to gather folks sitting at the intersection of Emily Oster, Dr. Volts, Jason Jacobs, and Elad Gil. Maybe I’m the only one. Maybe there’s dozens of us.
The Power of Noticing: Scott Loarie on Building a Global Biodiversity Movement with iNaturalist
What if the most important step you can take for biodiversity is simply… noticing?
Species are disappearing far faster than we can track, and for many of them, our entire scientific record amounts to a handful of specimens scattered across museum shelves.
My guest today, Scott Loarie (https://www.linkedin.com/in/scott-loarie-872b665/), has spent the last decade building one of the most hopeful counterforces to that trend: iNaturalist (https://www.inaturalist.org/). What started as a simple idea — “What if anyone could help record the living world with their phone?” — has grown into one of the largest biodiversity datasets on Earth. Most of what scientists now know about many species comes not from elite field research, but from millions of everyday people noticing what’s around them.
We talk about how climate change scrambles ecosystems, how citizen science has outpaced some traditional biology, and why biodiversity may be one of the last unpolarized environmental spaces left. iNaturalist works not because it’s high-tech, but because it taps into something deeply human: curiosity. A butterfly in your backyard becomes a datapoint for global science. A moment of noticing becomes a contribution that actually matters.
In a world where climate action often feels abstract and distant, biodiversity offers something intimate: a reason to look closer.
If you want to start, download the iNaturalist app, step outside, and snap a photo. It’s a tiny act that scales surprisingly far.

40 years of climate economics and the practice of hope with Professor Gary Yohe
How do you make decisions for the next hundred years based on evidence you only know today? That’s the question Gary Yohe has spent more than four decades wrestling with. One of the first five economists in the world working on climate change back in the early 1980s, Gary served as the Coordinating Lead Author for multiple IPCC report chapters, including the Fourth Assessment that shared the 2007 Nobel Peace Prize. His research has shaped how the world understands climate risk, bridging economics, science, and policy. Instead of chasing a perfect century-long plan, he argues we should treat climate as a risk management problem—act, learn, adjust. It’s an idea that changed the field: policy as an iterative process rather than a single bet on the future.
We talk about how this shift happened and what it means today, from San Francisco’s sea-level strategy—where most of the city plans for a two-foot rise, but why the Embarcadero prepares for six—to the limits of insurance as climate risk becomes unpriceable. Gary channels John Holdren’s line that “we can abate, we can adapt, or we can suffer,” and explains why the catastrophic tail risks will never be fully insurable. He shares lessons from decades of human behavior research: how Florida’s hurricane-proof houses paradoxically increased deaths as people stopped evacuating, and how Outer Banks homeowners started building intentionally ‘disposable’ beach houses when insurance vanished. Along the way, he reflects on the communication gap that dogs climate science—how misinformation can be careless, but accuracy must be flawless—and the discipline it takes to keep public trust.
Now in his seventies, Gary calls himself “a foot soldier in the climate wars.” What keeps him going isn’t blind optimism but something sturdier. Quoting Václav Havel, he distinguishes hope from optimism: optimism expects things will work out; hope believes your actions might make a difference. That’s what motivates him when he imagines his nine-year-old twin granddaughters asking, “Papa, what did you do when all this was happening?” His answer: “I was doing everything I could. And I really thought I might make a difference. And that gave me enough hope to think it was worth the time to do it.”

Turning acres into options with Aarden AI CEO Danan Margason
Agriculture, forestry, and land use together account for nearly 24 % of global greenhouse gas emissions. Yet somehow land sits in a weird blind spot: ignored by climate conversations focused on energy and transport, underanalyzed by markets, and mispriced by farmers and timber investors alike. That’s the problem, and opportunity, we’re going to discuss today.
I sit down with Danan Margason (https://www.linkedin.com/in/dananmargason/), founder and CEO of Aarden (https://aarden.ai/), to explore how AI can help land owners understand their options. Aarden sits at the center of a messy, trillion-dollar decision problem—enabling landowners and capital allocators to evaluate a single parcel across radically different paths: timber harvests vs. solar fields, carbon projects vs. housing, restoration now vs. monetizing later.
We dive into the systems thinking behind land use and why this is such a massive market that’s been underserved by technology.
Along the way, Danan shares his journey from crew boats in Seattle to Booking.com, through Carbon Direct’s push for high-quality removals, and into company-building back with his original crew buddy.
