Episode Details

How is Yosemite National Park a microcosm for our warming, fire-driven, world? 

Arizona State University emeritus professor Stephen Pyne answers that question in Pyrocene Park: A Journey Into the Fire History of Yosemite National Park (U Arizona Press, 2023). Pyne frames the fire history of Yosemite National Park around a three day hike he and a team of researchers took into the park's backcountry as part of a program examining the effects of changing fire regimes over the last several decades. 

In the process, Pyne explains how and why the human abolition - and reignition - of fires in the park have had dramatic effects on a place which is 95% wilderness. People, Pyne argues, have a strange relationship with fire, at once keeping the elemental process at arm's length while simultaneously being intertwined culturally and even physically with fire and its effects. As fires grow and the planet warms, Pyne asks readers to consider Yosemite as both a warning about the dangers of misunderstanding fire, and an example of how to respect fire as the ecological necessity it has always been.
