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.
