A podcast about how we can build a world of water abundance for everyone.

Charles Allen, Engagement Director for the Audubon Delta unit of the National Audubon Society and co-founder of the Lower 9th Ward Center for Sustainable Engagement and Development, joins John to reflect on nearly 20 years since Hurricane Katrina and what it means for New Orleans today. They discuss his experience with post-Katrina recovery, the importance of community-led rebuilding, and how neighborhoods have navigated uneven redevelopment. Charles also explores how communities can stay engaged on the impacts of climate change and why public participation is key to building long-term resilience.

Dr. Marshall Shepherd, Director of the Atmospheric Sciences Program at the University of Georgia, joins John to discuss the fourth transformation: how tropical storms and extreme weather are intensifying in frequency and power. From hurricanes moving further inland to the compounding effects of heatwaves and heavy rainfall, Marshall explains the science behind these shifts and the growing challenges they pose for communities across the U.S. Together, they explore the critical steps needed to adapt, rethink infrastructure, and address inequities in how extreme weather impacts vulnerable populations.

Tyler Antrup, an urban planner focused on climate adaptation and water management, professor at Tulane School of Architecture, and member of the Sewerage and Water Board, joins John to discuss the complex water challenges facing New Orleans. From green infrastructure to mitigate flooding, to the creeping threat of saltwater intrusion into drinking water systems, Tyler shares insights on adapting urban environments to the realities of climate change. They explore the evolving dynamics between stormwater management, subsidence, and sea level rise, as well as the critical role of community-based organizations in driving innovation.

Dr. Allison Lassiter, Assistant Professor in City and Regional Planning at the University of Pennsylvania, joins John to discuss one of the hidden dangers of sea level rise—saltwater intrusion. With expertise in climate adaptation and urban water management, Dr. Lassiter explains how rising salinity threatens drinking water systems, agriculture, and infrastructure. Together, they explore the costly solutions, like desalination, and why small communities face unique challenges. They also discuss the role of state-level strategies and innovative financing in building resilient water systems for the future.

Meredith McInturff, manager of the Public Health Emergencies and Environmental Health Unit at the New Orleans Health Department, joins John to discuss how the New Orleans Health Department is evolving to meet the growing threats of extreme heat. She and John explore the public health challenges faced by vulnerable populations, from unsheltered individuals to transit riders and outdoor workers, and how these challenges are shaping new city policies and cross-sector partnerships aimed at heat resilience.

Jesse Keenan, the Favrot II Associate Professor of Sustainable Real Estate and Urban Planning and the Founding Director of the Center for Climate Change and Urbanism at Tulane University, joins John to discuss the second transformation: Heat is moving north due to climate change, affecting regions and cities unprepared for prolonged high temperatures. Rising temperatures are straining public health systems, housing stability, and economic resilience, and driving new migration patterns across the U.S.

John Sabo continues the conversation on the first transformation —the deserts of the west moving eastward—with Brian Smoliak, an entrepreneur and climate scientist at Two Degrees Adapt. Brian shares insights on how climate change is affecting agriculture, and discusses innovative solutions helping farmers adapt. 

In Episode 1 of Season 4, John Sabo speaks with Jonathan Overpeck, a renowned climate scientist and Dean for the School for Environment and Sustainability at the University of Michigan. Peck discusses his role in defining critical climate change terms such as “tipping point” and “mega-drought, how climate change is exacerbating drought conditions in the Western U.S. and spreading aridification across the Midwest, and strategies for adaptation, including changes in agricultural practices and the management of water resources.

In Season 4 of Audacious Water, host John Sabo dives into how climate change is reshaping the Mississippi River Basin. He'll explore five different transformations over ten episodes with experts and people on the front lines to find out what's happening and how we can take action. Join us as we explore a future shaped by climate change. The new season starts next month.
