Not Cool: A Climate Podcast was one of the last projects I did with the Future of Life Institute, and it was one of my favorites. Below you'll find all 26 episodes of the Not Cool series, as well as a few other podcasts with climate researchers and experts that I hosted over the years.
Although this series was produced in 2019, the basics behind climate science remain the same today. Researchers continually learn more about the details of the environmental crisis, but the information below will be relevant for a long time. This is truly a master class with some of the world's leading experts and researchers explaining the climate, environmental, economic and human crises facing our world today and well into the future.
Thank you to Kirsten Gronlund who put in so much work as the producer of this series!
On the premier of Not Cool, Ariel is joined by John Cook: psychologist, climate change communication researcher, and founder of SkepticalScience.com. Much of John’s work focuses on misinformation related to climate change, how it’s propagated, and how to counter it.
On the second episode of Not Cool, Ariel delves into some of the basic science behind climate change and the history of its study. She is joined by Dr. Joanna Haigh, an atmospheric physicist whose work has been foundational to our current understanding of how the climate works.
What is a climate tipping point, and how do we know when we’re getting close to one? On Episode 3 of Not Cool, Ariel talks to Dr. Tim Lenton, Professor and Chair in Earth System Science and Climate Change at the University of Exeter and Director of the Global Systems Institute.
On Episode 4 of Not Cool, Ariel explores the concept of climate adaptation — what it means, how it’s being implemented, and where there’s still work to be done. She’s joined by Jessica Troni, head of UN Environment’s Climate Change Adaptation Unit, who talks warming scenarios, adaptation strategies, implementation barriers, and more.
Planning for climate change is particularly difficult because we're dealing with such big unknowns. But we at least know that in order to minimize the negative effects of climate change, we need to make major structural changes — to our energy systems, to our infrastructure, to our power structures — and we need to start now.
What is geoengineering, and could it really help us solve the climate crisis? The sixth episode of Not Cool features Dr. Alan Robock, meteorologist and climate scientist, on types of geoengineering solutions, the benefits and risks of geoengineering, and the likelihood that we may need to implement such technology.
The impacts of the climate crisis don’t stop at rising sea levels and changing weather patterns. Episode 7 of Not Cool covers the national security implications of the changing climate, from the economic fallout to the uptick in human migration. Ariel is joined by Lindsay Getschel, a national security and climate change researcher.
On the eighth episode of Not Cool, Ariel tackles the topic of climate policy from the local level up through the federal. She's joined by Suzanne Jones: public policy veteran, climate activist, and [former] mayor of Boulder, Colorado. Suzanne explains the climate threats facing communities like Boulder and measures local governments can take to combat the crisis.
On Episode 9 of Not Cool, Ariel is joined by Andy Revkin, acclaimed environmental journalist and founding director of the Initiative on Communication and Sustainability at Columbia University's Earth Institute. Andy discusses the information gaps that have left us vulnerable and the strategies we should be using to effectively communicate climate science.
On the tenth episode of Not Cool, Ariel takes a closer look at the research linking climate change and extreme events — and, in turn, linking extreme events and socioeconomic patterns. She’s joined by Stephanie Herring, a climate scientist at the National Oceanic and Atmospheric Administration whose work on extreme event attribution has landed her on Foreign Policy magazine’s list of Top 100 Global Thinkers.
While a single extreme weather event can wreak considerable havoc, it's becoming increasingly clear that such events often don't occur in isolation. Not Cool Episode 11 focuses on compound weather events: what they are, why they’re dangerous, and how we've failed to prepare for them. Ariel is joined by Jakob Zscheischler, an Earth system scientist at the University of Bern, who discusses the feedback processes that drive compound events, the impacts they're already having, and the reasons we've underestimated their gravity.
On episode 12 of Not Cool, Ariel is joined by Kris Ebi, professor at the University of Washington and founding director of its Center for Health and the Global Environment. Kris explains how increased CO2 affects crop quality, why malnutrition might alter patterns of human migration, and what we can do to reduce our vulnerability to these impacts.
What is ecosystem-based adaptation, and why should we be implementing it? The thirteenth episode of Not Cool explores how we can conserve, restore, and manage natural ecosystems in ways that also help us adapt to the impacts of climate change. Ariel is joined by Val Kapos, Head of the Climate Change and Biodiversity Programme at UN Environment’s World Conservation Monitoring Center, who explains the benefits of ecosystem-based adaptation along with some of the strategies for executing it.
Not Cool episode 14 examines the rapidly expanding domain of carbon finance, along with the wider economic implications of the changing climate. Ariel is joined by Filippo Berardi, an environmental management and international development specialist at the Global Environment Facility (GEF). Filippo explains the international carbon market, the economic risks of not addressing climate change, and the benefits of a low carbon economy.
Despite the global scale of the climate crisis, its impacts will vary drastically at the local level. Not Cool Episode 15 looks at the unique struggles facing different communities — both human and non-human — and the importance of equity in climate adaptation. Ariel is joined by Astrid Caldas, a senior climate scientist at the Union of Concerned Scientists, to discuss the types of climate adaptation solutions we need and how we can implement them.
How can artificial intelligence, and specifically machine learning, be used to combat climate change? In an ambitious recent report, machine learning researchers provided a detailed overview of the ways that their work can be applied to both climate mitigation and adaptation efforts. The massive collaboration, titled “Tackling Climate Change with Machine Learning,” involved 22 authors from 16 of the world's top AI institutions. On Not Cool episodes 16 and 17, Ariel speaks directly to some of these researchers about their specific contributions, as well as the paper's significance more widely.

In many ways, the global carbon budget is like any other budget. There’s a maximum amount we can spend, and it must be allocated to various countries and various needs. But how do we determine how much carbon each country can emit? On episode 18 of Not Cool, Ariel is joined by Glen Peters, Research Director at the Center for International Climate Research (CICERO) in Oslo. Glen explains the components that make up the carbon budget, the complexities of its calculation, and its implications for climate policy and mitigation efforts.
Carbon emissions account for about 50% of warming, yet carbon overwhelmingly dominates the climate change discussion. On Episode 19 of Not Cool, Ariel is joined by Ilissa Ocko for a closer look at the non-carbon causes of climate change — like methane, sulphur dioxide, and an aerosol known as black carbon — that are driving the other 50% of warming.
On the 20th episode of Not Cool, Ariel explores the many ways in which forests impact the global climate — and the profound price we pay when we destroy them. She’s joined by Deborah Lawrence, Environmental Science Professor at the University of Virginia whose research focuses on the ecological effects of tropical deforestation. Deborah discusses the causes of this year's Amazon rain forest fires, the varying climate impacts of different types of forests, and the relationship between deforestation, agriculture, and carbon emissions.
On Not Cool episode 21, Ariel is joined by Libby Jewett, founding Director of the Ocean Acidification Program at the National Oceanic and Atmospheric Administration (NOAA), who explains the chemistry behind ocean acidification, its impact on animals and plant life, and the strategies for helping organisms adapt to its effects.
On Not Cool episode 22, Ariel is joined by Cullen Hendrix, co-author of “Climate as a risk factor for armed conflict.” Cullen, who serves as Director of the Sié Chéou-Kang Center for International Security and Diplomacy and Senior Research Advisor at the Center for Climate & Security, explains the main drivers of conflict and the impact that climate change may have on them.
On Not Cool Episode 23, Ariel talks to Brian Toon, one of the five authors of the 1983 paper that first outlined the concept of nuclear winter. Brian discusses the global tensions that could lead to a nuclear exchange, the process by which such an exchange would drastically reduce the temperature of the planet, and the implications of this kind of drastic temperature drop for humanity.
Defunding the fossil fuel industry is one of the biggest factors in addressing climate change and lowering carbon emissions. But with international financing and powerful lobbyists on their side, fossil fuel companies often seem out of public reach. On Not Cool episode 24, Ariel is joined by Ellen Quigley and Natalie Jones, who explain why that’s not the case, and what you can do — without too much effort — to stand up to them.
On Not Cool episode 25, Ariel is joined by Mario Molina, Executive Director of Protect our Winters, a non-profit aimed at increasing climate advocacy within the outdoor sports community. In this interview, Mario looks at climate activism more broadly: he explains where advocacy has fallen short, why it's important to hold corporations responsible before individuals, and what it would look like for the US to be a global leader on climate change.
It’s the Not Cool series finale, and by now we’ve heard from climate scientists, meteorologists, physicists, psychologists, epidemiologists and ecologists. We’ve gotten expert opinions on everything from mitigation and adaptation to security, policy and finance. Today, we’re tackling one final question: why should we trust them? Ariel is joined by Naomi Oreskes, Harvard professor and author of seven books, including Why Trust Science? Naomi lays out her case for why we should listen to experts, how we can identify the best experts in a field, and why we should be open to the idea of more than one type of "scientific method."
Below are three other podcast episodes I hosted before the Not Cool series. They may be a bit more dated with, frankly, more hope that we can keep the world below 1.5 degrees of warming. However, again, the science is otherwise still just as relevant.
Does the climate crisis pose an existential threat? And is that even the best way to formulate the question, or should we be looking at the relationship between the climate crisis and existential threats differently? In [this] FLI podcast, Ariel was joined by Simon Beard and Haydn Belfield of the University of Cambridge’s Center for the Study of Existential Risk (CSER), who explained why, despite the many unknowns, it might indeed make sense to study climate change as an existential threat.
It’s not just about the natural world. The side effects of climate change remain relatively unknown, but we can expect a warming world to impact every facet of our lives. In fact, as recent research shows, global warming is already affecting our mental and physical well-being, and this impact will only increase. Climate change could decrease the efficacy of our public safety institutions. It could damage our economies. It could even impact the way that we vote, potentially altering our democracies themselves. Yet even as these effects begin to appear, we’re already growing numb to the changing climate patterns behind them, and we’re failing to act.
On this month’s podcast, Ariel spoke with Alexander Verbeek and John Moorhead about what we can do to avoid the worst of climate change. Alexander is a Dutch diplomat and former strategic policy advisor at the Netherlands Ministry of Foreign Affairs. He created the Planetary Security Initiative where representatives from 75 countries meet annually on the climate change-security relationship. John is President of Drawdown Switzerland, an act tank to support Project Drawdown and other science-based climate solutions that reverse global warming.
