Since 1973, the Tyler Prize for Environmental Achievement has been bestowed upon people who have made a significant impact in the fight for a sustainable planet. Last week on Sea Change Radio, we spoke with noted activist climate scientist Michael Mann, who was one of two recipients of this year’s Tyler Prize. This week, we are honored to speak with the other Tyler Prize Laureate, Warren Washington, to learn about the beginnings of his groundbreaking career as an atmospheric scientist. Dr. Washington was the second African American to receive a PhD in meteorology. He’s a former chair of the National Science Board, and currently a senior scientist at the National Center for Atmospheric Research in Boulder, Colorado. After our conversation with Dr. Washington, we chat with this year’s Tyler Prize panel moderator Kelly Sims-Gallagher, a professor at the Fletcher School of Law and Diplomacy, about the evolving intersection of global affairs and climate science.
