Peter Gleick and the Three Ages of Water

If you are not a member yet, now is the time to join our community and receive the great benefits of membership.

This year’s precipitation across California is well above average, and snowpack is on track to be one of the largest since 1950. In an arid state that can seem like good news, but floods can be destructive and life-threatening, and they also increase vegetation that may later go up in flames. From too little to too much—will we ever get out of this weather whiplash?

As we enter an era defined by climate disruption, the control, access and quality of water determines our ability to survive and thrive. How can we ensure a future where clean water exists for all who need it—including the ecosystems we depend on—and navigate the challenges of too little or too much? In his latest book, The Three Ages of Water, Dr. Peter Gleick explores this changing dynamic from life’s beginnings to today’s pressing climate and water challenges. 

Join Climate One Co-host Ariana Brocious for a live conversation with Peter Gleick about our evolving relationship with this fundamental force.

Safety Protocols for in-person attendance:
