Book Review | Fire Weather - A True Story from a Hotter World Sceptre by John Vaillant

John Vaillant Fire Weather: A True Story from a Hotter World Sceptre, an imprint of Hachette India, London, 2023. Pb. Pp. 441

In May 2016, a Canadian oil town was overrun by wildfire, turning entire neighbourhoods into firebombs and driving 90,000 people from their homes.

Fire Weather is an astounding account of this century's most intense urban fire, and an urgent examination of humanity's future in an ever-hotter, more flammable world. Vaillant's fourth book, Fire Weather: The Making of a Beast, follows the events and aftermath of the 2016 Fort McMurray wildfire, which caused billions of dollars’ worth of damage and destroyed around 2400 homes and forced the evacuation of over 80,000 people. It describes the anthropological history between humans and fire, how it has shaped our societies, and how it now threatens them in the context of climate change. Through the gripping story of this apocalyptic conflagration, John Vaillant explores our relationship with fire, an energy source that has been our partner in evolution for hundreds of millennia, shaping our culture and civilization. Now, in our age of intensifying climate change, its destructive power has been unleashed in ways previously unimaginable.

Opinion writer David Wallace-Wells of The New York Times said that the book was, “unfortunately, exquisitely timed.” The book’s release coincided with the start of several days of hazardous smoke levels and a thick yellowish haze across the eastern United States due to profuse smoke plumes from Canadian wildfires that drifted south. In 2025, the book continues to be relevant with the ongoing wildfire devastation in California that are being fuelled by the strong Santa Ana winds. John Vaillant wrote a piece on 11 Jan 2025: “We built our world with fire. Now heat is destroying our lives.” In it he states:

Fire has been our constant, if unreliable, companion since long before we found our way out of Africa: its spritely charisma and night-cancelling, animal-intimidating power was instrumental, not only to our ancestors’ survival, but to our evolution – to us becoming us.

So integral has fire become to our daily activities, and to our identities, that we scarcely notice it any more. Almost invisibly now, its superhuman potency enables and amplifies virtually everything we do: cooking our food, heating our homes, powering our energy grids, and driving us – in our teeming billions – through the world at lethal speeds by land, sea and air.

Fire, represented by its avatars, coal, oil and gas, is our superpower, pure and simple, and we can almost be forgiven for believing that we’ve mastered it. But we glossed over a crucial detail: we aren’t the only ones being supercharged. Due to the colossal scale on which our fire-powered civilisation now operates – including 50,000 seagoing ships, 30,000 jet planes, and nearly 2bn motor vehicles, powered by 100m barrels of oil every day – we have also supercharged the atmosphere.

Our atmosphere is a weather engine, and it is energised by heat. Thanks to the historic amounts of CO2 and methane generated by emissions from the uncountable fires we ignite every day, we have empowered fire much as it has empowered us, enabling it to burn hotter, faster, longer and more broadly across any environment containing hydrocarbons (a steadily broadening menu that now includes the margins of Greenland, and which could, in our lifetimes, include Antarctica).

All that extra energy released by our combustive activities (talk about 0% containment) causes normal weather events – such as wildfires in southern California – to metastasise into full-blown catastrophes that violate natural boundaries of season, geography and historic norms. The LA fires, as shocking as their damage is to behold, and as traumatising as they are for those affected by them, are just one manifestation of the atmospheric monster that fossil fuel emissions have loosed upon the world.

Fire was awarded Britain's £50,000 Baillie Gifford Prize for Non-Fiction in November 2023. It was also the finalist for multiple awards such as the Pulitzer Prize, the National Book Award, Writers' Trust Award, and the Wainwright Conservation Prize. Vaillant was also awarded the prestigious 2014 Windham–Campbell Literature Prize in Nonfiction, achievement award then valued at $150,000, and since 2023 it is $175,000 — the largest of its kind.

Prologue

On a hot afternoon in May 2016, five miles outside the young petrocity of Fort McMurray, Alberta, a small wildfire flickered and ventilated, rapidly expanding its territory through a mixed forest that hadn’t seen fire in decades. This fire, farther off than the others, had started out doing what most human- caused wildfires do in their first hours of life: working its way tentatively from the point of ignition through grass, forest duff, and dead leaves— a fire’s equivalent to baby food. These fuels, in combination with the weather, would determine what kind of fire this one was going to be: a creeping, ground-level smolder doomed to smother in the heavy dew of a cool and windless spring night, or something bigger, more durable, and dynamic— a fire that could turn night into day and day into night, that could, unchecked and all-consuming, bend the world to its will.

It was early in the season for wildfires, but crews from the Wildfire Division of Alberta’s Ministry of Forestry and Agriculture were on alert. As soon as smoke was spotted, wildland firefighters were dispatched, supported by a helicopter and water bombers. First responders were shocked by what they saw: by the time a helicopter with a water bucket got over it, the smoke was already black and seething, a sign of unusual intensity. Despite the firefighters’ timely intervention, the fire grew from 4 acres to 150 in two hours. Wildfires usually settle down overnight, as the air cools and the dew falls, but by noon the following day this one had expanded to nearly 2,000 acres. Its rapid growth coincided with a rash of broken temperature records across the North American subarctic that peaked at 33°C on May 3 in a place where temperatures are typically between 15 and 20°C. On that day, Tuesday, a smoke- and wind-suppressing inversion lifted, winds whipped up to twenty knots, and a monster leaped across the Athabasca River.

Within hours, Fort McMurray was overtaken by a regional apocalypse that drove serial firestorms through the city from end to end—for days. Entire neighborhoods burned to their foundations beneath a towering pyrocumulus cloud typically found over erupting volcanoes. So huge and energetic was this fire-driven weather system that it generated hurricane-force winds and lightning that ignited still more fires many miles away. Nearly 100,000 people were forced to flee in what remains the largest, most rapid single-day evacuation in the history of modern fire. All afternoon, cell phones and dashcams captured citizens cursing, praying, and weeping as they tried to escape a suddenly annihilating world where fists of heat pounded on the windows, the sky rained fire, and the air came alive in roaring flame. Choices that day were stark and few: there was Now, and there was Never.

A week later, the fire’s toll conjured images of a nuclear blast: there was not just “damage,” there was total obliteration. Trying to articulate what she saw during a tour of the fire’s aftermath, one official said, “You go to a place where there was a house and what do you see on the ground? Nails. Piles and piles of nails.” More than 2,500 homes and other structures were destroyed, and thousands more were damaged; 2,300 square miles of forest were burned. By the time the first photos were released, the fire had already belched 100 million tons of carbon dioxide into the atmosphere, much of it from burning cars and houses. The Fort McMurray Fire, destined to become the most expensive natural disaster in Canadian history, continued to burn, not for days, but for months. It would not be declared fully extinguished until August of the following year.

Wildfires live and die by the weather, but “the weather” doesn’t mean the same thing it did in 1990, or even a decade ago, and the reason the Fort McMurray Fire trended on newsfeeds around the world in May 2016 was not only because of its terrifying size and ferocity, but also because it was a direct hit—like Hurricane Katrina on New Orleans—on the epicenter of Canada’s multibillion-dollar petroleum industry. That industry and this fire represent supercharged expressions of two trends that have been marching in lockstep for the past century and a half. Together, they embody the spiraling synergy between the headlong rush to exploit hydrocarbons at all costs and the corresponding increase in heat-trapping greenhouse gases that is altering our atmosphere in real time. In the spring of 2016, halfway through the hottest year of the hottest decade in recorded history, a new kind of fire introduced itself to the world.

“No one’s ever seen anything like this,” Fort McMurray’s exhausted and grieving fi re chief said on national TV. “The way this thing happened, the way it traveled, the way it behaved—this is rewriting the book.”
