S2E47: Being a "witness" to climate change—w/ Dr. Evan Kuehn of North Park University
What does it mean to be a witnessing professional in the climate crisis?
What responsibility do scientists, doctors, journalists, lawyers, military officers and public health officials have to speak out and share their message of truth with the world? How does the religious concept of bearing witness translate to this secular context? And what can you and I do to become constructive witnesses for climate change?
Dr. Evan Kuehn is an Assistant Professor of Informational Literacy at North Park University and the author of Troeltsch’s Eschatological Absolute and Theology Compromised: Schleiermacher, Troeltsch, and the Possibility of a Sociological Theology. On this episode of Reversing Climate Change, Dr. Kuehn joins Ross to discuss the recent Dædalus issue on Witnessing Climate Change, describing what it means to be a witness, how the concept shifts from a sacred to a secular context, and what risks are associated with witnessing in public as a professional.
Dr. Kuehn explores Robert Socolow’s idea of witnessing for the middle to depolarize the climate conversation, explaining what it looks like to engage in situational ethics and sharing how he deals with extreme views and guillotine memes. Listen in for Dr. Kuehn’s insight around the Jewish tradition of preserving social criticism and learn what you can do to be a middle builder and serve as a constructive witness for climate change.

There are so many things referenced in this episode and not much space to add them all here unfortunately. If Anchor ups their character cap we will add them all back in.
N.B. Ross couldn't remember at the time of recording which scholar provided that insight about Jewish scripture preserving social criticism in this episode, but is pretty sure it came from Amy-Jill Levine, and most likely her Great Courses lecture series on the Old Testament.

S2E45: Synthetic biology & the holy grail of ag—w/ Mike Miille, CEO of Joyn Bio
Much of agriculture depends upon synthetic fertilizer. But the production of that fertilizer is responsible for 3% of greenhouse gas emissions. That’s why innovators in the emerging field of synthetic biology are attempting to disrupt the status quo in agriculture and engineer new ways for growers to achieve the same yields with less fertilizer—and less environmental impact.
Mike Miille is the CEO of Joyn Bio, a biotech company that is using synthetic biology to try to make agriculture more sustainable. On this episode of Reversing Climate Change, Mike joins Ross and Rebekah to explain how his team is engineering microbes to address unmet needs in agriculture and what differentiates synthetic biology from classical breeding or GMOs.
Mike introduces us to Joyn Bio’s work in designing nitrogen-fixing corn (the potential holy grail), responding to the argument that our system of monoculture isn’t worth saving and the concerns around scaling innovations in synthetic biology. Listen in to understand how Mike thinks about the unknowns of designing new organisms and learn about the other potentially game-changing advancements in ag that Mike’s team is working on right now.

S2E44: Can permaculture scale?—w/ Mark Shepard, author of Restoration Agriculture
We have destroyed or severely disrupted many of the perennial ecosystems that were here in favor of annual crops. Crops that require the use of herbicide and mulch year after year until, eventually, the soil is depleted and we move on. So, how can we use the design principles of permaculture to restore the ecology of the planet, provide ourselves with all the food, fuels and fibers we need, and make money while we’re at it? And at scale no less!
Agroforestry farmer and permaculturist Mark Shepard is the CEO of Forest Agriculture Enterprises, Founder of Restoration Agriculture Development, and award-winning author of Restoration Agriculture: Real-World Permaculture for Farmers. On this episode of Reversing Climate Change, Mark joins Ross and Christophe to share his understanding of permaculture, explaining how he applies its principles in a way that allows for scale and designs practical systems around the individual farmer’s machinery.
Mark introduces us to his idea of STUN agriculture (Strategic Total Utter Neglect), describing how nature solves every problem farmers have—at no cost and with very little effort. Listen in for insight on where science falls short in supporting the transition to restoration agriculture and learn how we can leverage permaculture to build economies around ecologically-designed systems.

S2E43: Salmon, the Earth, & their common fate—w/ Mark Kurlansky, author
There are only 1.5M Atlantic salmon left in the world. And despite putting an end to commercial fishing, their numbers continue to dwindle. As a keystone species, the implications of their loss go far beyond not being able to order salmon for dinner. So, why are Atlantic salmon disappearing at such an alarming rate? What does their loss mean for other species? And how does it impact the rivers where they live?
Mark Kurlansky is a New York Times bestselling and James A. Beard award-winning author with a knack for seeing the broader implications of seemingly little things. He has written 33 books in all, including The Big Oyster: History on the Half Shell, Cod: A Biography of the Fish That Changed the World and most recently, Salmon: A Fish, the Earth, and the History of Their Common Fate. His forthcoming book, The Unreasonable Virtue of Fly Fishing is due out in March of 2021.
On this episode of the podcast, Mark joins Ross to share what inspired him to choose salmon as the topic of his most recent book and explain why climate change is catastrophic for the fish. He weighs in on the problems with salmon farming (be it inland or on the water) and discusses why hatcheries are not a viable way to enhance the salmon population. Listen in for Mark’s insight on how the disappearance of Atlantic salmon will impact other species and learn how to be a conscious consumer of the popular fish.

S2E42: The national security implications of climate change—w/ Dr. Rod Schoonover
We have explored, at length, the basket of biophysical stressors climate change could produce. And we’ve looked at how floods, droughts, tropical cyclones, ocean acidification, coral degradation (and the list goes on and on) might impact our food security and lead to the displacement of a lot of people. But what does the climate crisis mean for national security? How does the intelligence community think about climate change?
Dr. Rod Schoonover is a member of The Center for Climate & Security Advisory Board. He is also the Founder and CEO of the Ecological Futures Group, and an Adjunct Professor in the School of Foreign Service at Georgetown University. He served in the US Intelligence Community for ten years as the Director of Environment and Natural Resources at the National Intelligence Council and Senior Analyst in the Bureau of Intelligence and Research at the US Department of State.
On this episode, Dr. Schoonover joins Ross to discuss the foreign policy goals of the US and share his concerns around the current administration’s failure to call out anti-democratic values. He explains how the suppression of his written testimony for the House Intelligence Committee regarding the national security implications of climate change led to his resignation from the State Department. Listen in for Dr. Schoonover’s insight on what the US government should do to address the climate crisis and learn what could happen (from a security perspective) if we don’t take action on climate change.

How do you tell a good story about the climate?—w/ Jess Miles, writer
The vast majority of environmental nonfiction follows a predictable pattern: The writer goes out in nature and then tells us why it’s important to preserve the thing they experienced. But what if we could reach more people and maybe even change their point of view with a more experimental, more whimsical approach?
Jess Miles is a recent graduate of Chatham University and author of the MFA thesis ‘Midnight Sun,’ a collection of essays about her time on the Arctic island of Svalbard. On this episode of Reversing Climate Change, Jess joins Ross to explain what inspired her to pursue science communication, sharing what she does to persuade readers and how she approaches environmental writing differently.
Jess opens up about her frustrating experience with canvassing for an environmental organization, describing what she learned about people (and herself!) and how she turned that bad experience into good writing. Listen in to understand why Jess incorporates elements of whimsy in her work and learn how experimental forms of writing can help readers see climate issues in a new light.

S2E41: Climeworks & European carbon removal—w/ Christoph Beuttler, CDR Manager at Climeworks
For years now, we have debated the potential moral hazard of carbon removal, the fear being that we will abandon emissions reductions for the quick fix of carbon capture. But the science is clear: we simply can’t achieve our climate goals with mitigation alone. So, how do we design policy that works toward net zero using a binding emissions reduction pathway AND a strategy for scaling up carbon removal?
Christoph Beuttler is the CDR Manager at Climeworks, the global leader in direct air capture technology. He also serves as the Deputy CEO of The Risk Dialogue Foundation and Founding Member of the Board for the Negative Emissions Platform. On this episode of Reversing Climate Change, Christoph joins Ross to discuss Climeworks’ modular approach to direct air capture, describing how they use solid sorbents to capture carbon dioxide and how that CO2 is either stored permanently or used to replace fossil inputs.
Christoph shares his understanding of carbon removal regulations in Europe, explaining how EU businesses interact with policy and why companies are driving voluntary carbon removal markets. Listen in for insight around the future of the carbon removal sector as a whole and learn how you can help Climeworks realize its audacious goal to achieve gigaton scale in the next two decades!

S2E40: Much talk of CO2, but what about methane?!—w/ Olya Irzak of Frost Methane
Carbon dioxide is not the only greenhouse gas that contributes to climate change. In fact, methane emissions are responsible for 16% of the warming we experience today. And because methane is more potent than CO2, we can make a big impact in a short period of time by addressing the concentrated, continuous methane seeps that exist around the world.
Olya Irzak is the Founder and CEO of Frost Methane, a company working to combat climate change through the deployment of remote methane destruction devices. On this episode of the podcast, Olya joins Ross and Christophe to discuss why she chose to focus on methane emissions and explain how her team’s technology works to convert concentrated methane into CO2.
Olya describes Frost Methane’s initial work with Arctic permafrost and introduces their new application of the technology in coal mines, sharing how the business generates revenue through carbon markets like California’s cap-and-trade market. Listen in for Olya’s insight on the benefits of voluntary markets and learn her approach to prioritizing climate interventions to make the biggest impact.
