In recent decades, large-scale wildfires have wreaked havoc, transforming landscapes from California to Portugal, and further afield to countries like Canada, Greece, and Australia. The question arises: Are we witnessing merely a series of environmental disasters, or is there a larger narrative at play? Observing these blazes, one might conclude that we are not just facing a future rife with fire but also a complex historical intertwining of humanity and its relentless companion—fire. As a historian investigating this relationship, I assert that our story is rich and layered, deserving of careful examination.
Fire has been an integral aspect of human existence for tens of thousands of years, shaping our species and surroundings alike. This historical bond is pivotal in understanding contemporary disasters. Humanity has co-evolved with fire, adjusting landscapes and ecosystems through activities ranging from agriculture to urban development. Yet, it has become painfully evident that our fire practices have morphed into a self-destructive cycle. Unlike the previous epochs characterized by natural fire ecosystems, we now generate an overwhelming intensity of combustion—our self-styled fire age, or what I would suggest is the “Pyrocene.”
The influence of humans on fire dynamics can be traced back to the cessation of the last ice age, around 11,500 years ago. As human populations adapted and changed their environments, they inadvertently made these ecosystems increasingly susceptible to fire. In the Americas, for example, the drastic depopulation from European colonization allowed forests to reclaim territories, sequestering vast amounts of carbon and potentially nudging the planet into a cooler period known as the Little Ice Age. However, these natural checks, which once regulated fire cycles, were produced over millions of years and have been severely disrupted by modern practices.
With the onset of industrialization and the global reliance on fossil fuels, our relationship with fire has fundamentally altered. Fossil fuel consumption has introduced a disconnect between natural fire roles and the combustion that props up our modern way of life. This “pyric transition” has created a clash between traditional fire environments and industrial fire, exacerbated by urbanization and climate change.
In our attempt to combat wildfires, we have turned to technology—bulldozers, pumps, and aerial support—rather than adapting our landscapes to coexist with fire. This has led to an alarming scenario where landscapes that previously thrived in balance with fire are now overwhelmed by rapid, uncontrolled burning. Historic land management practices aimed at preventing wildfires have often backfired, allowing fuel loads to accumulate, setting the stage for even more catastrophic and frequent fires.
The intertwining of climate change and land use policies has created a feedback loop, producing an incrementally worsening fire situation. While climate change receives considerable attention as a driving force behind wildfire frequency and intensity, it is crucial not to overlook the historic legacy of our land management practices and their compounding effects.
As we plow ahead with policies that inadequately address the dual roles of fire in our ecosystems, it’s becoming increasingly evident that we are not merely fighting a series of fires but are entrenched in a broader ecological crisis. Just as hurricanes require warm oceans to thrive, modern megafires draw on myriad factors ignited by our industrial activities. We find ourselves in a situation where human practices surrounding fire are leading to vast ecological changes.
Looking ahead, we must confront an unsettling reality: Earth appears poised on the brink of a new epoch defined by unprecedented fire activity. If we expand our vision, we can anticipate a planet where fire plays a predominant role, akin to the historical ice ages that reshaped Earth. This transition to a more flame-ridden world, punctuated by unprecedented ecological shifts and possible mass extinctions, urges us to reconsider our relationship with fire as both a natural force and a product of human engineering.
In the final analysis, the Pyrocene embodies far more than an environmental crisis; it epitomizes our complicated entanglements with fire. The way we manage the land, adopt technologies, and maneuver climate change collectively paints a complex future deeply rooted in our historical narratives. If there is one lesson to be gleaned amid this chaos, it is that our choices now will unfurl in the cycles of fire and life in the years to come. It’s time we reconcile our history with foresight, shaping an equitable and sustainable coexistence with fire rather than combating it from merely a logistical standpoint. The reality of California’s fiery landscape serves as a cautionary tale—we must act before we are engulfed by the flames of our own making.
