California is lurching between extremes—from record-breaking heat and low mountain snowpack to torrential atmospheric river events and catastrophic wildfire. In this episode of Terra Verde, host and producer Hannah Wilton speaks with climate scientist Dr. Daniel Swain about the phenomenon of “hydroclimate whiplash” and what it reveals about the future of the American West.

Dr. Swain unpacks how atmospheric dynamics are being amplified by climate change, what we learned from Los Angeles’s devastating fires last year, and why rapidly shifting wet-to-dry cycles are challenging water management and disaster preparedness across the state. The conversation also explores what’s at stake for American science as institutions like the National Center for Atmospheric Research face potential dismantling—and why California may have an opportunity to lead in rebuilding climate research capacity.

You can follow Dr. Swain’s work through his widely-read Weather West blog, where he offers real-time perspectives on California weather and climate, as well as on X, Bluesky, and YouTube.
