Carbon Dioxide: Earth's Thermostat

Decouple ·

2025/09/22

This week, award-winning science writer Peter Brannen returns to Decouple to explore the 4.5 billion-year story of carbon dioxide on Earth. Grounding our discussion is his new book, The Story of CO2 Is The Story of Everything. From the alien world of the Hadean eon to humanity's emergence as the "pyromaniac ape," Brannen reveals how this trace gas has shaped every aspect of our planet's evolution, through Snowball Earth, mass extinctions, and the rise of complex life, culminating

2025/09/15

Professor Alex Wellerstein returns from the set of WIRED (watch his excellent appearance here) to help me understand the origins of Middle Eastern nuclear programs and where they stand today. From France’s covert assistance to Israel’s bomb program in the 1960s to the mysterious Vela incident over the South Atlantic, Wellerstein shows how nuclear weapons spread through unofficial networks of scientists, spies, and opportunistic allies. We explore Iran’s strategic nuclear hedging, Israel’s policy of

2025/09/08

This week, we talk about rare earth metals. What are they, where do they come from, and how are they redefining global power? I’m joined by David Abraham, a natural resource strategist who saw the future of rare earths in 2010 while working in Japan's Ministry of Economy, Trade and Industry. When China cut off rare earth exports over a territorial dispute, Abraham realized these obscure elements, sprinkled into our steel, the magnets in our speakers, the phosphors in our screens, held more

The Export Expert

Decouple ·

2025/08/18

This week, we talk about Russian nuclear exports. Michael Seely, host of AtomicBlender, joins me to discuss the rise of Rosatom: Russia’s nuclear energy behemoth that now builds nearly half of the world’s new reactors. We trace its formation after the Soviet collapse, its grip on the nuclear fuel market, and its unmatched “turnkey” model for newcomer nations. Rosatom’s nuclear exports are more than just a commercial endeavour—they can reshape global influence for decades.Michael's videos on

#289 - Breaking the Ice

Decouple ·

2025/08/12

This week, we travel to the edge of the map with Aleksandr Surtcev, an engineer who has crewed Russian nuclear icebreakers along the Northern Sea Route. We explore how Russia’s Arctic fleet keeps this strategic corridor open, why floating nuclear plants are powering remote communities and mines, and what life looks like in a place where polar bears trail ships for fish and resupply markets pop up on the ice. Beneath the stories lies a deeper discussion of geopolitics, engineering, and the hard

The State of the Atom (2025)

Decouple ·

2025/07/28

This week, Mark Nelson joins us to deliver his second annual “State of the Atom” address. The nuclear power landscape has transformed in the last two years. Russia continues its nuclear export dominance while the West at last awakens from its stupor, driven by an unexpected force: artificial intelligence's insatiable appetite for baseload power. From Amazon's billion-dollar Susquehanna deal to Three Mile Island's resurrection, Big Tech is discovering what nuclear advocates have long

This week, we talk solar power—a long overdue topic on Decouple. In the past, guests have often been critical of the value of renewables on grids without extensive storage, and of the quality of jobs that politicians often claim when justifying renewables programs. Today, however, we drop preconceptions and get to the nuts and bolts. My guest is Seaver Wang, director of the Climate and Energy Research Program at The Breakthrough Institute. Despite is imperfections, the solar power has a remarkable

Small Reactor, Big Price

Decouple ·

2025/07/02

We have an unusual episode today. One, because of its length (1 hour 40 minutes), and two, because I’m the guest. Joined by Aidan Morrison as acting host, I talk about a topic of intense interest to me: the Darlington SMR project in Ontario, Canada. I’ve been critical of this SMR project, which recently received its final investment decision, by calling for a pivot to CANDU reactors at the site.I use this episode to break down all my reasons for being critical, and to concede ground to this bold SMR

2025/06/25

This week, we return to nuclear power. Specifically, nuclear construction and “learning curves.” It is intuitive that doing something over and over makes you better at it. In industry, this means driving down costs and timelines and boosting efficiencies. In many industries, the truth of learning curves is readily apparent. However, in Western nuclear construction it has been largely absent for decades. Robbie Stewart, CTO of Alva Energy, joins me to dissect why the nuclear industry struggles with

2025/05/13

In the wake of Europe's largest blackout in decades, commodities investor Alexander Stahel helps us to understand the physics of power grids, and how Spain's celebrated renewable transition became its Achilles' heel. He introduces the “hellbrise” phenomenon—excessive, rather than too little, renewable generation—as he considers the role of grid inertia in preventing minor disruptions from cascading into failures in mere seconds. Spanish energy policy isn’t the first time that green
