On this edition of the Perpetual Notion Machine, we speak with University of California-Berkeley professor and author David Sedlak about his latest book Water for All: Global Solutions for a Changing Climate, published in 2023 by Yale University Press. In it, he identifies six water crises and sites ways these could be mitigated to meet water needs across the globe–not only for people, but for ecosystems.

David Sedlak is the Plato Malozemoff Professor of Civil and Environmental Engineering at the University of California, Berkeley, and director of the Berkeley Water Center. He earned his Ph.D. in Water Chemistry from the University of Wisconsin at Madison in 1992 and B.S. in Environmental Science from Cornell University in 1986.  He is the author of the award-winning book Water 4.0: The Past, Present, and Future of the World’s Most Vital Resource. David’s Ted Talk, Four ways we can avoid catastrophic drought has over a million views.

This interview originally aired in two parts on February 8 and 15, 2024.
