A conversation with Stephen Pyne, the world’s most prominent wildfire historian

The world's most prominent wildfire historian found his way into his life's work by accident. A few days after he graduated from high school, Stephen Pyne had been brought on as a laborer on the South Rim of the Grand Canyon and was signing his hiring papers when he was asked if he’d be interested in joining a forest fire crew on the North Rim instead.
“I said sure,” Pyne told me. “And it was transformative. Everything I’ve done since then dates from that time on the North Rim.”
Pyne spent fifteen seasons on the North Rim, including twelve as a crew boss, and went on to study fire for a living. He became a fire historian, practically the first of his kind, joined the faculty at Arizona State University, and wrote dozens of books about the history of fire around the world. He retired from teaching in 2018, but continues to work on books — he’s wrapping up one about Mexico at the moment.
I spoke with Pyne about the history of wildfires in the United States, and what the future could look like. Our interview has been edited for length and clarity.
How have we historically thought about fire in the United States?
Well, it depends what time in history you want to go back to. The attitudes we have now are pretty recent, probably less than 100 years. The native peoples used fire widely, for all kinds of things. Heating, lighting, entertainment, agriculture, hunting, foraging, and self-protection. It was all over the place.
Europeans also had fire in their background, but always embedded within an agricultural context of pastoralism or farming. Nobody was particularly putting fires out unless it immediately threatened some asset of theirs, like their house or town. It was just sort of spring clean, part of maintenance of the landscape. So people were always around fire, it was just a constant companion. And then that changes when we began going to industrial combustion, powered by fossil fuels. Suddenly, we don't have fire around us anymore.
Where did it go?
Well, it went into machines. The burning is done off-site and we get the fire through electricity. Processed fossil biomass gave us a lot of the petrochemicals we use for agriculture, so we don't burn the fields for fertilizing and fumigating. We found all these substitutes and then we use machines to deliver those things. So it's taken fire out of the built environment.
When did the American policy of fire suppression really come into being? Was there a turning point?
A couple of things happened. Part of it is we have a long run almost 50 years after the Civil War of very large and disastrous fires. They were associated with clearing settlement, widespread logging, and a lot of it was catalyzed by railroads, which were also a source of these large, disastrous fires that were probably an order of magnitude larger than what we've seen in recent years. Hundreds of people were killed.
And then in the summer of 1910, a series of large fires sort of amassed into what became known as the Big Blowup. This was about three and a quarter million acres burned in the Northern Rockies, killing 78 firefighters the Forest Service had hired in six different incidents all at the same time, during the afternoon and evening of August 20. Traumatized the US Forest Service, which at the time was five years old.
Its leaders determined they were never going to allow that to happen again, and the two guys who were in charge of the firefighting in the Northern Rockies became chief foresters during the 1920s and 1930s. So it was just one generation of leaders, mostly younger men, who were traumatized, and the easiest way to sell the message of what they were doing was to eliminate all fires. The urban elites understood that message, because that's how urban fire services work.
So we spent about 50 years trying to take all fires out of the landscape. And we've spent the last 50 years trying to put good fire back in.
How’s that been working?
It turns out fire is one of these things that’s easy to remove and hard to reinstate. It’s like a threatened species — if you want to reintroduce a species to a landscape, you often find that a lot of conditions have changed. That’s tough to work with.
What are the conditions that have changed that made reintroducing fires so hard?
Well, a lot of it is just the forest changed. And this was a result of overgrazing. selective logging, or outright clear cutting, which allowed stuff to grow back in ways that are outside the norm. Sheep and cattle have stripped away the grasses that made light [more manageable] fires possible, and other stuff grew up in their place. Now you've paved the landscape with dense layers of pine needles and shrubs, and they don’t burn the same way, so you've created a fire trap. All of this actually started with westward expansion, before the Forest Service entered the scene.
And so that 50 year period of suppression must’ve made it worse.
Yeah, that was really disastrous. By the ‘60s, we see pushback. We’d seen the consequences. And I'll point out that this is well before global climate change is on anybody’s agenda. These landscapes were messed up ecologically. Trees and other species weren’t regenerating.
So what starts happening in the ‘60s?
We saw civil society begin to create an alternative to state-sponsored fire suppression. There was a ranch north of Tallahassee that began hosting fire ecology conferences in 1962, they really introduced the term fire ecology. That same year, the Nature Conservancy conducted its first burn at a prairie because they couldn’t maintain the prairie without burning.
It was a real David versus Goliath story. Forestry was too dyed-in-the-wool hostile towards fire. They had sort of made their public identity as firefighters. But all kinds of things started coming together and there was the sentiment that fire should be restored just like wolves and grizzlies.
You mentioned burning had historically been done by the indigenous communities. How involved were those communities in these discussions? Were they involved at all?
Almost none. There were some people who was reintroducing fire to indigenous reservations, but they were foresters with the Bureau of Indian Affairs. But it’s only much more recently that [Native American communities] have sort of taken on cultural burning as a way of restoring their identities and their traditions and maybe even claiming back some of their lands.
We often say that colonialism suppressed indigenous knowledge. Well, that’s true. But something that gets lost, I think, all the time, is that there was a quarrel between the elites and traditional knowledge. Europe’s elites treated Europe’s peasants with disdain as well. Many of the white settlers who weren’t elites used fire as well, but the elites didn’t like that.
Obviously in the last couple of weeks Hawaii has been on everyone's mind. What’s the history of fire in Hawaii?
Before it was colonized, Hawaii was fairly immune to fire. The forests don’t seem to have been particularly responsive to it. You have lightning caused fires, you have volcanoes that set fires but then the lava was the bigger problem there.
Fire in Hawaii starts with human contact, when they begin clearing the forest and introducing exotics. This started with Polynesians before Europeans got into the act. There was a lot of extermination particularly of flightless birds and they introduced pigs and rats and other things. But then it really began accelerating with European contact, when they converted large areas to plantations for sugar and pineapples or grass pastures to raise cows, and so forth. So you have larger scale land clearing that goes on.
But Hawaii was not built to burn in the way California is. We created more combustible landscapes. Tropical grasses grow very well there and burn very well, and once they burn they create conditions that are more favorable to themselves. So it’s a positive feedback system.
We’ve seen a lot of coverage about how climate change is going to intensify wildfires. What do you, as a person who studies wildfires from around the world, think needs to happen going forward?
I mean, these really nasty megafires we've seen recently and that are doing a lot of damage to communities are really a pathology of the developed world. You don’t you don’t see these in the developing world. They have lots of burning, but they don’t have these massive fires.
I think we need to do three things, and we need to do them at the same time. The first is to protect our communities. It’s totally absurd that we have so many fires started by power lines. There’s no reason for towns to burn, and we know how to keep them from burning. So hardening our cities is the first step. The second is we need to recover the countryside. Not just wild lands, but the countryside. We have to put it into a shape that makes fire control easier and will probably also enhance the biology of the site. There are a lot of controversies around that, and there’s but we have got to have ways of negotiating all those values and perceptions. But that’s something that can be done.
The third thing we need to do is tame climate change. We can do a lot of mitigation but at some point unless the accelerating climate upheaval isn’t stopped and even reversed, it will override all the other stuff we do.
Do you think of fire as something to fear?
I think there’s bad fire. Bad fire kills people, it destroys towns, it can trash ecosystems. Fire can do a lot of damage, but it can also be absolutely essential. So it’s not either good or bad.
We have a species monopoly over fire. We made a mutual assistance pact with it a long time ago. You have to tend it, you have to feed it, you have to train it, you have to clean up after it. You have to integrate it into social activities. It’s not just a physical tool like a hammer or an axe that can be picked up and put down. It’s something we domesticated in a way. And we’ve lost control over what’s been a companion that we’ve had for all our existence as a species.
We are fire creatures. You know, we use fire in a way that no other creature does. We’ve abrogated that role. We’ve abused it. But it’s only in the last century or so that we have lost the capacity to manage fire. So this is just us reclaiming our heritage and taking responsibility for the power that our relationship with fire gave us. It’s not beyond our ability to deal with it.

There has been no new nuclear construction in the U.S. since Vogtle, but the workers are still plenty busy.
The Trump administration wants to have 10 new large nuclear reactors under construction by 2030 — an ambitious goal under any circumstances. It looks downright zany, though, when you consider that the workforce that should be driving steel into the ground, pouring concrete, and laying down wires for nuclear plants is instead building and linking up data centers.
This isn’t how it was supposed to be. Thousands of people, from construction laborers to pipefitters to electricians, worked on the two new reactors at the Plant Vogtle in Georgia, which were intended to be the start of a sequence of projects, erecting new Westinghouse AP1000 reactors across Georgia and South Carolina. Instead, years of delays and cost overruns resulted in two long-delayed reactors 35 miles southeast of Augusta, Georgia — and nothing else.
“We had challenges as we were building a new supply chain for a new technology and then workforce,” John Williams, an executive at Southern Nuclear Operating Company, which owns over 45% of Plant Vogtle, said in a webinar hosted by the environmental group Resources for the Future in October.
“It had been 30 years since we had built a new nuclear plant from scratch in the United States. Our workforce didn’t have that muscle memory that they have in other parts of the world, where they have been building on a more regular frequency.”
That workforce “hasn’t been building nuclear plants” since heavy construction stopped at Vogtle in 2023, he noted — but they have been busy “building data centers and car manufacturing in Georgia.”
Williams said that it would take another “six to 10” AP1000 projects for costs to come down far enough to make nuclear construction routine. “If we were currently building the next AP1000s, we would be farther down that road,” he said. “But we’ve stopped again.”
J.R. Richardson, business manager and financial secretary of the International Brotherhood of Electric Workers Local 1579, based in Augusta, Georgia, told me his union “had 2,000 electricians on that job,” referring to Vogtle. “So now we have a skill set with electricians that did that project. If you wait 20 or 30 years, that skill set is not going to be there anymore.”
Richardson pointed to the potential revitalization of the failed V.C. Summer nuclear project in South Carolina, saying that his union had already been reached out to about it starting up again. Until then, he said, he had 350 electricians working on a Meta data center project between Augusta and Atlanta.
“They’re all basically the same,” he told me of the data center projects. “They’re like cookie cutter homes, but it’s on a bigger scale.”
To be clear, though the segue from nuclear construction to data center construction may hold back the nuclear industry, it has been great for workers, especially unionized electrical and construction workers.
“If an IBEW electrician says they're going hungry, something’s wrong with them,” Richardson said.
Meta’s Northwest Louisiana data center project will require 700 or 800 electricians sitewide, Richardson told me. He estimated that of the IBEW’s 875,000 members, about a tenth were working on data centers, and about 30% of his local were on a single data center job.
When I asked him whether that workforce could be reassembled for future nuclear plants, he said that the “majority” of the workforce likes working on nuclear projects, even if they’re currently doing data center work. “A lot of IBEW electricians look at the longevity of the job,” Richardson told me — and nuclear plants famously take a long, long time to build.
America isn’t building any new nuclear power plants right now (though it will soon if Rick Perry gets his way), but the question of how to balance a workforce between energy construction and data center projects is a pressing one across the country.
It’s not just nuclear developers that have to think about data centers when it comes to recruiting workers — it’s renewables developers, as well.
“We don’t see people leaving the workforce,” said Adam Sokolski, director of regulatory and economic affairs at EDF Renewables North America. “We do see some competition.”
He pointed specifically to Ohio, where he said, “You have a strong concentration of solar happening at the same time as a strong concentration of data center work and manufacturing expansion. There’s something in the water there.”
Sokolski told me that for EDF’s renewable projects, in order to secure workers, he and the company have to “communicate real early where we know we’re going to do a project and start talking to labor in those areas. We’re trying to give them a market signal as a way to say, We’re going to be here in two years.”
Solar and data center projects have lots of overlapping personnel needs, Sokolski said. There are operating engineers “working excavators and bulldozers and graders” or pounding posts into place. And then, of course, there are electricians, who Sokolski said were “a big, big piece of the puzzle — everything from picking up the solar panel off from the pallet to installing it on the racking system, wiring it together to the substations, the inverters to the communication systems, ultimately up to the high voltage step-up transformers and onto the grid.”
On the other hand, explained Kevin Pranis, marketing manager of the Great Lakes regional organizing committee of the Laborers’ International Union of North America, a data center is like a “fancy, very nice warehouse.” This means that when a data center project starts up, “you basically have pretty much all building trades” working on it. “You’ve got site and civil work, and you’re doing a big concrete foundation, and then you’re erecting iron and putting a building around it.”
Data centers also have more mechanical systems than the average building, “so you have more electricians and more plumbers and pipefitters” on site, as well.
Individual projects may face competition for workers, but Pranis framed the larger issue differently: Renewable energy projects are often built to support data centers. “If we get a data center, that means we probably also get a wind or solar project, and batteries,” he said.
While the data center boom is putting upward pressure on labor demand, Pranis told me that in some parts of the country, like the Upper Midwest, it’s helping to compensate for a slump in commercial real estate, which is one of the bread and butter industries for his construction union.
Data centers, Pranis said, aren’t the best projects for his members to work on. They really like doing manufacturing work. But, he added, it’s “a nice large load and it’s a nice big building, and there’s some number of good jobs.”
A conversation with Dustin Mulvaney of San Jose State University
This week’s conversation is a follow up with Dustin Mulvaney, a professor of environmental studies at San Jose State University. As you may recall we spoke with Mulvaney in the immediate aftermath of the Moss Landing battery fire disaster, which occurred near his university’s campus. Mulvaney told us the blaze created a true-blue PR crisis for the energy storage industry in California and predicted it would cause a wave of local moratoria on development. Eight months after our conversation, it’s clear as day how right he was. So I wanted to check back in with him to see how the state’s development landscape looks now and what the future may hold with the Moss Landing dust settled.
Help my readers get a state of play – where are we now in terms of the post-Moss Landing resistance landscape?
A couple things are going on. Monterey Bay is surrounded by Monterey County and Santa Cruz County and both are considering ordinances around battery storage. That’s different than a ban – important. You can have an ordinance that helps facilitate storage. Some people here are very focused on climate change issues and the grid, because here in Santa Cruz County we’re at a terminal point where there really is no renewable energy, so we have to have battery storage. And like, in Santa Cruz County the ordinance would be for unincorporated areas – I’m not sure how materially that would impact things. There’s one storage project in Watsonville near Moss Landing, and the ordinance wouldn’t even impact that. Even in Monterey County, the idea is to issue a moratorium and again, that’s in unincorporated areas, too.
It’s important to say how important battery storage is going to be for the coastal areas. That’s where you see the opposition, but all of our renewables are trapped in southern California and we have a bottleneck that moves power up and down the state. If California doesn’t get offshore wind or wind from Wyoming into the northern part of the state, we’re relying on batteries to get that part of the grid decarbonized.
In the areas of California where batteries are being opposed, who is supporting them and fighting against the protests? I mean, aside from the developers and an occasional climate activist.
The state has been strongly supporting the industry. Lawmakers in the state have been really behind energy storage and keeping things headed in that direction of more deployment. Other than that, I think you’re right to point out there’s not local advocates saying, “We need more battery storage.” It tends to come from Sacramento. I’m not sure you’d see local folks in energy siting usually, but I think it’s also because we are still actually deploying battery storage in some areas of the state. If we were having even more trouble, maybe we’d have more advocacy for development in response.
Has the Moss Landing incident impacted renewable energy development in California? I’ve seen some references to fears about that incident crop up in fights over solar in Imperial County, for example, which I know has been coveted for development.
Everywhere there’s batteries, people are pointing at Moss Landing and asking how people will deal with fires. I don’t know how powerful the arguments are in California, but I see it in almost every single renewable project that has a battery.
Okay, then what do you think the next phase of this is? Are we just going to be trapped in a battery fire fear cycle, or do you think this backlash will evolve?
We’re starting to see it play out here with the state opt-in process where developers can seek state approval to build without local approval. As this situation after Moss Landing has played out, more battery developers have wound up in the opt-in process. So what we’ll see is more battery developers try to get permission from the state as opposed to local officials.
There are some trade-offs with that. But there are benefits in having more resources to help make the decisions. The state will have more expertise in emergency response, for example, whereas every local jurisdiction has to educate themselves. But no matter what I think they’ll be pursuing the opt-in process – there’s nothing local governments can really do to stop them with that.
Part of what we’re seeing though is, you have to have a community benefit agreement in place for the project to advance under the California Environmental Quality Act. The state has been pretty strict about that, and that’s the one thing local folks could still do – influence whether a developer can get a community benefits agreement with representatives on the ground. That’s the one strategy local folks who want to push back on a battery could use, block those agreements. Other than that, I think some counties here in California may not have much resistance. They need the revenue and see these as economic opportunities.
I can’t help but hear optimism in your tone of voice here. It seems like in spite of the disaster, development is still moving forward. Do you think California is doing a better or worse job than other states at deploying battery storage and handling the trade offs?
Oh, better. I think the opt-in process looks like a nice balance between taking local authority away over things and the better decision-making that can be brought in. The state creating that program is one way to help encourage renewables and avoid a backlash, honestly, while staying on track with its decarbonization goals.
The week’s most important fights around renewable energy.
1. Nantucket, Massachusetts – A federal court for the first time has granted the Trump administration legal permission to rescind permits given to renewable energy projects.
2. Harvey County, Kansas – The sleeper election result of 2025 happened in the town of Halstead, Kansas, where voters backed a moratorium on battery storage.
3. Cheboygan County, Michigan – A group of landowners is waging a new legal challenge against Michigan’s permitting primacy law, which gives renewables developers a shot at circumventing local restrictions.
4. Klamath County, Oregon – It’s not all bad news today, as this rural Oregon county blessed a very large solar project with permits.
5. Muscatine County, Iowa – To quote DJ Khaled, another one: This county is also advancing a solar farm, eliding a handful of upset neighbors.
