WILDFIRES AT THE EDGES OF SCIENCE: Horizoning
Work amid Runaway Change
ADRIANA PETRYNA

**Runaway Change and Climate Projections** *Understanding Runaway Change* Runaway change, as defined by climate scientists, signifies a rapid deviation from long-established baselines, patterns, or historical trends. This phenomenon transforms into more than just an aggregation of ecological surprises, challenging the concept of projection itself. Although climate models offer predictions about the ongoing impact of climate change, they struggle to accurately forecast specific events like megafires or superstorms (NPR 2016). The enigmatic nature of runaway change defies conventional models and explanations, showcasing how projections degrade and highlighting the unchecked progression of climate change. It embodies the disparity between expectations and reality, appearing as a vacuum where phenomena like wildfires vanish. The critical question becomes: How can this change be made visible and possibly slowed? We must explore how temporal horizons are adapted for runaway change, determining if actionable time can be reclaimed from its relentless pace. *Scientific Endeavors and Ecological Dynamics* Over the past decade, scientists have focused on rapidly altering global climate elements. Key concepts include critical thresholds and regime shifts, addressing sudden shifts in ecosystem dynamics (Lenton 2011; Dakos et al. 2012; Scheffer et al. 2012; Drijfhout et al. 2015). Critical thresholds indicate moments where behaviors deviate from established norms, leading to regime shifts that impact ecosystem structures and functions. These shifts threaten the current ecological environment, imposing unforeseen survival constraints. Initially manifesting as anomalies, these changes may cement into a new organizational state, observable on regional or specific scales. However, by the time these changes are fully acknowledged, it may be too late to adapt. *Conclusion* Understanding runaway change and its implications demands a reevaluation of how we perceive and model climate dynamics. This calls for an urgent exploration of predictive models and an investigation into actionable strategies to manage the change effectively.

**WILDFIRES AT THE EDGES OF SCIENCE: Horizoning Work amid Runaway Change** **Author: Adriana Petryna** *University of Pennsylvania* [ORCID: http://orcid.org/0000-0002-8952-7559](http://orcid.org/0000-0002-8952-7559) --- The year 2015 had been the worst wildfire-fighting year on record in the United States. Wildfires consumed 10 million acres, and the war on wildfire cost taxpayers $2.6 billion. In California alone, about 3,400 wildfires were fought, 1,000 more than the average over the previous five years. Fire seasons are lasting, on average, eighty-six days longer than they have in four decades. For two weeks in 2015, recruiters in the national dispatch and coordination system hit a resource limit: there was simply nobody left to recruit to fight the fires. Military personnel, volunteers, and even prisoners were conscripted into emergency response efforts. The truth is that it is hard to find stability in these numbers. As the future unfolds, these numbers (of acres burned or costs accrued for any given year) become distant benchmarks of runaway change. This became evident in 2017, when new records were set and dispatch services once again hit novel breaking points with exhausted fire crews and widespread pollution and destruction. California, with more than nine thousand fires, saw the first ever wintertime megafires in December of that year, during “what should be the peak of the state’s rainy season” (Holthaus 2017). As one observer of these fires noted: “I was expecting to see snow on that mountain, and now the thing is on fire” (Downey 2017). --- *CULTURAL ANTHROPOLOGY, Vol. 33, Issue 4, pp. 570–595, ISSN 0886-7356, online ISSN 1548-1360. © American Anthropological Association 2018.
