In this week’s episode, host Margaret Walls talks with Matt Chambers, a researcher at the Institute for Resilient Infrastructure Systems at the University of Georgia, about managing floods with nature-based solutions. Chambers discusses the history of levee systems in the United States, the challenges that the widespread use of levees have presented, and approaches to floodplain management that help restore ecosystems while improving community resilience to flooding. He also discusses the economic analysis that informs floodplain management and the evolution of the US Army Corps of Engineers as a key decisionmaker in the management of US rivers.

In this week’s episode, host Daniel Raimi discusses subsidies for carbon capture and storage (CCS) with Sheila Olmstead, a professor at the Cornell Jeb E. Brooks School of Public Policy and a senior faculty fellow at the Cornell Atkinson Center for Sustainability. Olmstead evaluates the complicated nature of the 45Q policy, a federal subsidy available to firms that implement CCS. While CCS subsidy programs promote the reduction of carbon emissions, Olmstead identifies these subsidies as having the potential to financially burden the federal government, discourage clean energy projects, and motivate more pollution.

Airing New Concerns with US Carbon Capture Policies, with Sheila Olmstead

This week’s episode features a discussion of the recent US federal investment in a privately held mine—the Mountain Pass Rare Earth Mine in California—with host Daniel Raimi and podcast guest Tom Moerenhout, a professor at Columbia University and leader of a critical minerals initiative at the Center on Global Energy Policy at Columbia University’s School of International and Public Affairs. Moerenhout talks about the current US dependence on foreign imports for rare earth elements, which are used to manufacture things like wind turbines, batteries, missiles, and airplanes. While recent federal investment in the Mountain Pass mine puts financial risk on the US government, Moerenhout says that this type of approach could help the United States reduce its reliance on other countries for rare earth elements.

In this week’s episode, host Daniel Raimi discusses carbon removal with Jennifer Wilcox, a professor at the University of Pennsylvania who recently coauthored a paper titled, “Elevating Carbon Management: A Policy Decision-Making Framework and Rubric for the 21st Century.” Wilcox discusses the existing gaps in current policies related to carbon removal and important considerations when amending and creating new policies. She also addresses the recent change to the 45Q subsidy (originally included in the Inflation Reduction Act of 2022 and revised by Congress in the budget reconciliation bill signed on July 4, 2025), assessing how the updated tax break offers incentives for carbon removal.

Achieving Societal Goals Through Carbon Removal, with Jennifer Wilcox

In this week’s episode, host Daniel Raimi talks with Arvind Ravikumar, an assistant professor at the University of Texas at Austin, about recent federal deregulation of methane emissions in the United States; specifically, the effects on methane emissions from the production of natural gas and liquefied natural gas. Ravikumar highlights some of his recent research, which explores how all steps in the supply chain of natural gas can affect emissions intensity—including transportation of the energy source to end users—and the variation in methane emissions across countries from their natural gas supply chains.

In this week’s episode, host Daniel Raimi and guest Severin Borenstein discuss regulatory punishments for “energy hogs.” Borenstein is a professor at the University of California, Berkeley; faculty director of Berkeley’s Energy Institute in the Haas School of Business; and chair of the board of governors for the California Independent System Operator. These “energy hogs”—households perceived as consuming wasteful and excessive amounts of electricity—may incur higher energy costs as states strive to meet economic and environmental goals. However, Borenstein’s work reveals that benign or even desirable factors, such as having more people in the household, can lead to higher energy use. Borenstein cautions regulators about charging certain households more than is needed to offset the social costs of electricity use. Together, Borenstein and Raimi talk about ways that US states can reach their policy goals without penalizing households that use more energy.

In this week’s episode, host Daniel Raimi talks with Dave Foster, a distinguished associate at the Energy Futures Initiative, about the story of how labor unions and environmental organizations have found ways to work together on issues that affect both contingents. As a former director of United Steelworkers District 11, Foster recalls the “Donora incident” as the main catalyst for the union’s interest in environmental affairs. Foster shares his firsthand recollection of the history behind the creation of the BlueGreen Alliance, including some of the various struggles, wins, and early initiatives that helped secure the partnership between labor and environmental organizations.

A History of Alliances Between Workers and Environmentalists, with Dave Foster

In this week’s episode, host Daniel Raimi talks with Vivek Srikrishnan about factors that contribute to sea level rise. Srikrishnan, an assistant professor at Cornell University, describes the difficulties involved in analyzing the impact of the complex factors related to climate and climate change, which in turn lead to uncertainties in projecting the extent of future sea level rise. In a new publication, Srikrishnan and coauthors model different scenarios that capture those uncertainties. Srikrishnan also points out how short-lived greenhouse gases can lead to greater ice melt compared to more persistent greenhouse gases, as well as the irreversible nature of ice melts.

Understanding Uncertainty in Climate Change and Sea Level Rise, with Vivek Srikrishnan

In this week’s episode, host Kristin Hayes talks with Kaitlin Raimi about public perceptions of solar geoengineering. Raimi, a social psychologist and associate professor at the University of Michigan, describes how only around 15 or 25 percent of people know what solar geoengineering is, and those who are aware tend to be wary of the concept. She discusses techniques to inform the public about the benefits and pitfalls of solar engineering, avoid political polarization, and prevent solar geoengineering from being seen as the only solution needed to tackle climate change.

Nature vs. Unnature: Public Perception of Solar Geoengineering, with Kaitlin Raimi

In this week’s episode, host Daniel Raimi talks with Neha Khanna and Ruohao Zhang about how government shutdowns prevent active air-pollution monitoring—and end up leading to more air pollution from coal-fired power plants while monitoring is on hiatus. Professor Khanna from Binghamton University and Assistant Professor Zhang from Pennsylvania State University published a related study, with another coauthor, examining the impact of the 2018–2019 government shutdown on pollution emissions from federally regulated coal-fired power plants. The authors found that the hiatus on pollution monitoring by federal employees, who were furloughed during the shutdown, led to an increase in the types of pollutants that required manual regulation at power plants. In this podcast episode, Khanna and Zhang reflect on how these findings may likewise inform how pollution rates may have changed during the government shutdown that ended just last week.

Pumping Up Pollution During Government Shutdowns, with Neha Khanna and Ruohao Zhang

In this week’s episode, host Daniel Raimi talks with Kate Gordon about California’s recent raft of climate policies. Gordon, the CEO of California Forward who also has held senior policy positions in California and the US Department of Energy, discusses the various Senate bills that have been proposed and passed recently in the state. She talks about the importance of considering energy affordability when addressing California’s energy and climate concerns and what she’s noticed as evolving perceptions of carbon management. Gordon also touches on specific bills that extend California's cap-and-trade program and ramp up permissions for oil drilling, sharing her own take on the current state of climate policy in California.
