Welcome to season three of Come Heck or Hot Water (formerly Fahrenheit 140)! As changes in climate put strains on our natural resources, we’ve decided to take a deep dive into one possible solution for resilience and long-term sustainability. Join our hosts, Robert and Carrie, for an overview of seawater desalination. In this episode, Dr. Robert E. Mace explains the ins and outs of this agent of resilience.
