In Season 3 of The Subverse, we are journeying into ‘fire’. In this opening episode, we speak with Prof. Stephen J. Pyne, a fire historian, urban farmer, and emeritus professor at Arizona State University, U.S.A. Pyne has written over 40 books, most of which are centred around fire. In this conversation, we focus on his book The Pyrocene: How we Created an Age of Fire, and What Happens Next, published in 2021. Apart from being such a prolific scholar of fire, Stephen J. Pyne spent 15 seasons with the North Rim Longshots, a fire crew at Grand Canyon National Park, 12 as crew boss, with another three seasons writing fire plans for other national parks. He lives in Queen Creek, Arizona. His next book is a fire history of Mexico.
Susan and Stephen discuss how fire is, for humans, our defining ecological trait. We are unique fire creatures on a unique fire planet, and as keepers of the flame, we need to somehow get the right mix of fire in the world to balance our interests and those of others. In his book, Pyne proposes a fire-centric perspective on how humans continue to shape the Earth. The book renames and redefines the so-called Anthropocene according to humanity’s primary ecological signature, which is our ability to manipulate fire. As he states in the book, “the sum of our fire practices is creating a fire age that is equivalent in stature to the ice ages of the Pleistocene.” In the narrative he lays out, the pyric prism he uses is what he terms as an ecological three-body problem.
The history that Pyne narrates chronicles three fires. First-fire is the fire of nature that appeared as soon as plants colonised continents, about 420 million years ago. Thanks to cooking, a dependence on fire became coded into hominin DNA. Second-fire was an act of domestication, perhaps the model for all pyrotechnologies, in which people had transformed wildfire into hearth and torch. Third-fire is qualitatively different. Pyne points out that third-fire burns lithic landscapes no longer bounded by ecological limits. With a source of combustibles, which are essentially unbounded, inadequate sinks for the effluent, from cooking food and landscapes, we are now cooking planets. The sum of Earth’s three fires is creating the fire-informed equivalent of an ice age, and instead of ice amassing more ice, fire is generating more fire. This pyric transition also means that fire vanished as a serious object of inquiry. Fire with its flame, glow, heat, and crackle has been reduced to the most elemental chemical and physical expressions, each isolated and engineered, so that what had been ‘fire’ became ‘combustion,’ and combustion has become only its constituent parts. What we erased were traditional and indigenous knowledges of living with fire.
