Understanding Wet-Bulb Temperature, Climate Extremes, & Systemic Risk—& How We Build Resilience - Colin Raymond | #56

The unfortunate reality is that, in a warming world, we're going to be learning about 'wet-bulb temperature' (WBT) the hard way more and more. These are temperatures at which it is hot enough to cause the human body heat stress and humid enough to prevent it from cooling off through sweat. So today's guest, Colin Raymond, joins me to dig into what they are & what we can do to stay safe & build resilience.As many of you know by now, I’m currently working on a book manuscript called How to Survive the 21st Century. Modest, I know. It’s a journalistic effort, in which I draw from the insights of experts in various fields to sketch the major crises we face today and what more effective responses to them might be. I’ve been fortunate to speak with many experts whose ideas I’ve already included in the book, but as I set out to work on my “Heat, Humidity, and Fire” chapter, I realized I’d never actually had a guest on who could speak to the issue of WBTsSupport the show by checking out: ProtonVPN (gold-standard VPN—fast and safe.

Which is why I was so excited to discover Colin’s work.Not only is he deeply knowledgeable about the topic of wet-bulb temperatures, and guides us through the risks they pose to us—but he also has expertise in the broader arena of climate extremes. Here are some titles of recent papers he’s authored and co-authored: “Do summertime atmospheric rivers meaningfully promote humid heat?” “How might extreme climate events be connected, and why does it matter?” and “How are key compound risks changing in a warming and moistening world?” He’s also facilitated workshops that seek to surface collective insights about these existential risks.Many scientists are content to stay in their narrow line—and there’s nothing wrong with that—but it takes a really special mind to take this transdisciplinary approach to their work. And that comes through in this conversation—so I’m going to get out of your way and let you hear it directly from Dr. Colin Raymond.BIO: Dr. Colin Raymond is a research scientist at the University of California, Los Angeles. His work centers on understanding the intricate interactions of weather, geography, and human systems that drive extreme humid heat and its impacts, now and in the future. He draws upon a variety of approaches, from direct observations and climate models to storyline development, in the service of producing and communicating accessible and actionable climate information.Find more episodes of Urgent Futures at: youtube.com/@UrgentFutures.
