S2E74: Sanitation and EJ concerns grow with climate change—w/ Catherine Coleman Flowers, MacArthur Genius
Do you take having a working sanitation system for granted?
What if you didn’t have access to a public wastewater treatment plant? What if you lived with sewage running back into your home? And what if your failing septic system made YOU a criminal?
MacArthur Fellow Catherine Coleman Flowers is the founder of The Center for Rural Enterprise and Environmental Justice (CREEJ) and author of Waste: One Woman’s Fight Against America’s Dirty Secret. On this episode of Reversing Climate Change, Catherine joins Ross to discuss the neglect of water and wastewater infrastructure in rural America, explaining why septic systems are failing and how that impacts public health.
Catherine offers insight on the disparities in access to sanitation for poor rural communities and people of color, describing how corrupt government officials and bad policy can contribute to the inequity. Listen in for Catherine’s advice on collaborating with people who don’t necessarily share your values and find out what CREEJ is doing to design a solution that will allow people to treat wastewater affordably—wherever they are.

Freedom, Mayhem, and the Uncertain Future of Revel’s Mopeds—w/ Kate Knibbs, Senior Writer at WIRED
If you don’t have access to public transportation or you’re looking for a climate-friendly alternative to Uber, then you may have considered renting one of Revel’s electric mopeds. But do micromobility companies like this actually make money? And how should micromobility fit into the larger ecosystem of getting from point A to point B?
Kate Knibbs is a Senior Writer at WIRED and the author of ‘Freedom, Mayhem, and the Uncertain Future of Revel’s Mopeds.’ On this bonus episode of Reversing Climate Change, Kate joins Ross and guest host Radhika Moolgavkar, Head of Supply and Methodology at Nori, to discuss micromobility, describing how mopeds and e-bikes should be a complement to mass transit—not the dominant form of getting around.
She offers insight on the potential profitability of a company like Revel, explaining how positioning itself as an electric vehicle company increases its chances of success and why safety issues are its greatest existential threat. Listen in to understand the role of subsidies in making micromobility ventures work and learn how Kate thinks about when to choose public transit, train travel, auto ownership, rideshare, or micromobility options.

S2E72: NFTs, carbon removal, & the music biz—w/ Imogen Heap, Grammy-winning artist
Data in the music industry is incredibly fragmented. There is no one consistent place to go for information about a work. It’s hard to know where songs are being played or who was involved in creating a piece of music. And this means that a lot of artists don’t get royalties for their work.
What if blockchain technology is the answer?
Imogen Heap is the Grammy Award-winning singer-songwriter and record producer behind The Creative Passport, an identity management platform for music makers that runs on the blockchain. On this episode of Reversing Climate Change, Imogen joins Ross, Paul, and Evangeline to explain how the music industry’s challenges around crediting and payment inspired her interest in the blockchain space.
She weighs in on why she launched a collection of non-fungible tokens (NFTs) to raise funds for The Creative Passport and how she devoted a portion of the proceeds to Nori to offset the carbon emissions associated with minting those NFTs. Listen in for Imogen’s vision of a more diverse commercial music industry where artists are empowered to host their own data and share it with others on the blockchain.

S2E69: Mark Bittman on the political economy of junk food
60% of the calories in our food supply are alleged to be ultra-processed junk. So, when did we lose our way? When did we go from growing food to feed our communities to growing food for profit? And how do we find our way back to a just food system—and society?
Mark Bittman is a former New York Times columnist and bestselling author of 30-plus books, including the well-known How to Cook Everything series. His new release is called Animal, Vegetable, Junk: A History of Food, from Sustainable to Suicidal. On this episode of Reversing Climate Change, Mark joins Ross and Radkhika to explain how the food system shaped our history and vice versa, describing how the Enclosure Movement may have turned food into a profit-making political tool and created the health crisis we’re facing.
He weighs in on why educating kids about good food is the first step in creating a just food system and advocates for subsidies to support getting good food to more people. Listen in for Mark’s perspective on investing federal dollars in regenerative agriculture and learn how he thinks about making the phrase ‘land reform’ common in our political discourse.

Replacing plastic with captured carbon: an update from Mark Herrema of Newlight Technologies
Since its founding in 2003, Newlight Technologies’ goal has been to create consumer-driven solutions to reducing carbon in the air. And while that intention has not changed, the Newlight team’s approach has evolved as they consider how to achieve the greatest impact.
Mark Herrema is the cofounder and CEO of Newlight, an advanced biotechnology company using greenhouse gas to produce sustainable materials and replacements for plastic. On this episode of Reversing Climate Change, Mark joins Ross and cohost Radkhika Moolgavkar, Head of Supply and Methodology at Nori, to discuss what Newlight has been up to since his last appearance on the podcast, explaining how they brought a new plant online in 2019 and why the team chose foodware and fashion as its first two consumer foci.
Mark shares an overview of the AirCarbon production process, addressing where Newlight’s greenhouse gas feedstocks come from and how Newlight uses the blockchain to track the carbon footprint of its products. Listen in to understand how Mark’s thinking around carbon markets has shifted, why it took two years to get Newlight’s methodology approved, and what marketplaces need to change to make the space more attractive to other ambitious entrepreneurs.

S2EP68: What would happen if our rivers ran wild?—w/ Tyler J. Kelley, author of Holding Back the River
Since the first levee was built in New Orleans in 1717, we have been trying to manage America’s rivers. But now our infrastructure is failing. And if we don’t compromise on a plan to restore (or strategically remove) our dams, levees, and locks and give our waterways more space, flooding events will continue to devastate entire communities over and over again.
Tyler J. Kelley is a journalist whose work has appeared in The New York Times, The Wall Street Journal, and The New Yorker, among many other national publications. His first book, Holding Back the River: The Struggle Against Nature on America’s Waterways, was published in April 2021. On this episode of Reversing Climate Change, Tyler joins Ross to explain why riverboat traffic is still important to the US economy, moving more than 1,000 semi-trucks’ worth of vital commodities daily.
Tyler discusses the extensive work we’ve done to manage rivers in the US, describing how much land would be unlivable without levees and why the risks of flooding will only increase with climate change. Listen in for Tyler’s insight on the Dutch Delta Works project to give land back to the rivers and fortify existing infrastructure and learn how we might create a similar comprehensive flood control plan to protect communities here in the US.
