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.

The delayed vote on a net-zero standard for the International Maritime Organization throws some of the industry’s grandest plans into chaos.
Today, members of the International Maritime Organization decided to postpone a major vote on the world’s first truly global carbon pricing scheme. The yearlong delay came in response to a pressure campaign led by the U.S.
The Net-Zero Framework — initially approved in April by an overwhelming margin and long expected to be formally adopted today — would establish a legally binding requirement for the shipping industry to cut its emissions intensity, with interim steps leading to net zero by 2050.
In the intervening months, however, U.S. opposition has gotten much louder. On Thursday, Trump posted on Truth Social that he’s “outraged that the International Maritime Organization is voting in London this week to pass a global Carbon Tax.” He also took the extraordinary step of threatening not to comply with the rules. “The United States will NOT stand for this Global Green New Scam Tax on Shipping, and will not adhere to it in any way, shape, or form.” If the framework ever does pass, noncompliance could subject U.S. vessels to fines or even denial of entry at the ports of IMO member countries, potentially setting off a cycle of retaliatory measures from all sides.
No specific date has yet been scheduled for the forthcoming vote, which will be taken again a year from now. That throws plans for the world’s largest shipping companies — some of which have already taken expensive measures to decarbonize their fleets — into turmoil. The framework would have marked a major turning point for a sector that’s responsible for 3% of global emissions, of course. But even more importantly, it would have made a range of decarbonization technologies — from advanced batteries and clean fuels to wind-assisted propulsion and onboard carbon capture — far more viable and attractive to investors.
Kate Danaher, managing director of the oceans team at S2G Investments, has a vested interest in the frameworks’ eventual passage. “Over the past two years people have really started investing around the anticipation of something like the Net-Zero Framework being adopted,” Danaher told me. For its part, S2G has invested in Sofar Ocean, which focuses on fuel savings through route optimization, battery company Echandia which is aiming to electrify smaller vessels, and ocean data and monitoring companies Xocean and Apeiron Lab.
The new rules were originally set to take effect in 2028, and would apply to large vessels — ships of 5,000 gross tonnage or more — involved in international voyages. Qualifying ships would be assigned a base target for emissions intensity and a stricter “direct compliance target.” For every metric ton of CO2 equivalent that exceeds the compliance target but falls below the base target, ships must pay $100. For all emissions that exceed the base target, ships must pay $380 per metric ton. Noncompliant ships would pay these penalties by purchasing so-called “remedial units” from a central IMO registry, while the cleanest vessels — those performing better than their compliance targets — would earn surplus units they can sell to others or bank for future use.
Green shipping fuels such as e-methanol, e-hydrogen, and e-ammonia — all produced from green hydrogen using renewable electricity — stand to be the biggest winners, she said. “A new fuel would completely decarbonize the industry. That is 10 years out, and is completely contingent on the IMO,” Danaher said, explaining that if the framework ultimately fails, there’s no economic incentive to adopt these more expensive fuels, which also require costly retrofits for existing fleets. But the framework would effectively cause the cost of conventional fuel to rise just as alternative fuels are scaling up, which would allow them to reach parity around 2035, she said.
A specialized agency within the United Nations, the IMO gets its power to set global regulations from the vastness of the ocean itself. Most of the world’s waters exist outside the jurisdiction of any national government. Because of that, IMO member states — which represent the vast majority of global shipping tonnage — have ratified treaties that empower the organization to set safety, security, and environmental standards on the high seas, which members then implement and enforce through their own national laws. Only member states have a stake in IMO policy. Furthermore, vessels that aren’t IMO-compliant face penalties such as fees and even possible detentions when entering the ports of IMO countries.
While IMO decisions are typically made via negotiated consensus, the contentious nature of these new regulations necessitates a vote. U.S. officials celebrated the delay. U.S. Secretary of State Marco Rubio posted on X that the postponement represents “another HUGE win for @POTUS,” going on to say that “the United States prevented a massive UN tax hike on American consumers that would have funded progressive climate pet projects.”
Along with Secretary of Energy Chris Wright, and Secretary of Transportation Sean Duffy, Rubio last week issued a statement threatening to punish nations that voted in favor of these “activist-driven climate policies” with actions such as banning their ships from U.S. ports, imposing vessel fees, and even leveling sanctions on officials supportive of the regulations.
Saudi Arabia — the world’s second largest oil producer after the U.S. — also strongly opposed the framework, as did a host of other oil-producing Middle Eastern countries, Indonesia, Malaysia, Pakistan, Thailand, Russia and Venezuela. Singapore ultimately put forth the motion to delay the adoption vote for a full year and Saudi Arabia called it to a vote. It passed with a simple majority, with 57 countries approving and 49 opposed.
When it comes to costs, Trump officials might actually have a point, Danaher conceded. “Once alternative fuels come online and people are actively paying penalties, it gets a lot more expensive,” she told me. “I don’t see how this isn’t incredibly inflationary to the global market in 10 years.”
Today’s standard low-sulfur fuel, she explained, costs about $500 per metric ton. But reaching the same energy density with e-methanol, for example, could push the price to around $2,000 a metric ton. “That is all going to get passed on, essentially, to the consumer,” she said.
Even so, the framework has the backing of major shipping trade organizations and industry giants alike, from the International Chamber of Shipping to Maersk. As a group of leading international maritime associations put it in an open letter last week, “Only global rules will decarbonise a global industry. Without the Framework, shipping would risk a growing patchwork of unilateral regulations, increasing costs without effectively contributing to decarbonisation.”
Indeed, a universal set of coherent rules is what many in the sector want most, Danaher affirmed. Some voting bodies, such as the EU and Singapore, have already set their own shipping-related emissions requirements, creating a regulatory patchwork that’s both costly and confusing for companies to comply with. “I think most people are like, let’s just do this. Let’s rip the Band-Aid off, and let’s get clarity,” Danaher told me.
In a statement released after the vote’s delay and the conclusion of the IMO’s days-long meeting in London, Thomas A. Kazakos, the shipping chamber’s secretary general, said, “We are disappointed that member states have not been able to agree a way forward at this meeting. Industry needs clarity to be able to make the investments needed to decarbonise the maritime sector, in line with the goals set out in the IMO GHG strategy.”
The delay also risks delegitimizing the power of the IMO as a whole, something the organization’s Secretary-General, Arsenio Dominguez, warned about in the meeting’s opening remarks on Tuesday, when he stated that “Prolonged uncertainty will put off investments and diminish confidence in IMO.”
There would be other ways for shippers to comply with the framework besides switching to e-fuels, Danaher told me. For example, S2G’s portfolio company Sofar Ocean operates a network of ocean sensors designed to improve marine weather predictions and power a route optimization platform that can help ships save time, fuel, and ultimately, emissions.
Software solutions have a pretty low barrier to adoption. But a step up in complexity — and cost — would involve a technology such as wind-assisted propulsion. The companies Norsepower and Anemoi, for example, use a cylindrical “rotor sail” that creates a powerful thrust as it spins, which they say allows for up to 25% to 30% fuel savings. Another approach is the “rigid wing sail,” such as that developed by Bar Technologies. This generates lift in the direction of the ship’s movement with less drag than a normal sail — similar to how an airplane wing works.
Pairing route optimization with wind-assisted propulsion will generate even greater emissions savings, as the software can direct ships towards areas with the most advantageous winds. Given the obvious co-benefits and cost savings stemming from lower fuel use, Danaher thinks this tech could gain traction even if the regulations ultimately fail to pass next year. “I think the adoption curve will still continue without IMO [Net-Zero Framework], but I think it'll be slower,” she told me.
One approach she doesn’t think will be economically viable without the framework is onboard carbon capture. This tech, which traps carbon dioxide from a ship’s exhaust system before it’s released into the atmosphere, is being explored by startups including Seabound — which I reported on last year — and Value Maritime, as well as more established companies such as Mitsubishi and Wartsila. “A lot of the carbon capture technologies have not yet solved for how to turn that captured carbon into a valuable resource, and how to get it off the boat, put it in a pipeline, and sell it,” Danaher told me.”The economic incentive just isn't there without the IMO.”
At the same time, when I talked to one of Seabound’s backers — Clea Kolster, of Lowercarbon Capital — last year, she told me that when it comes to cargo shipping, “carbon capture is probably the only way that you can get a meaningful amount of emissions reductions in any near term way.” And it’s true that alternative fuels will take a while to scale up, so if the framework is ultimately adopted, carbon capture may still have an important role to play — at least that’s what investors and startups alike are banking on. “Everybody's talking about carbon capture in anticipation of this getting adopted,” Danaher told me. “All these vessels are going to be old, they’re going to need to comply, and they’re not going to be able to comply fast enough,” she said.
Amidst the turmoil, one silver lining is that interest in maritime innovation and efficiency appears to be increasing regardless of global frameworks. For one, the surge in global military spending has underscored this tech’s potential for dual-use applications. “A lot of wars happen in and around the oceans, because that’s where we intersect each other the most.” Danaher told me. Many of S2G’s investments in ocean tech have received additional backing from governments and defense agencies looking to make their fleets more efficient, energy resilient, and secure. “Every single one of our ocean tech companies, one of their customers is the government, or many governments,” she said.
It’s an important reminder that there are many practical reasons for investors and states alike to support a decarbonization agenda, regardless of whether the U.S. is on board or not. But a global system of carrots and sticks sure wouldn’t hurt either. And now, we face the uneasy prospect of waiting another year to see whether the shipping industry will resist the Trump-era pushback or abandon its collective ambitions for a decarbonized future.
Amarillo-area residents successfully beat back a $600 million project from Xcel Energy that would have provided useful tax revenue.
Power giant Xcel Energy just suffered a major public relations flap in the Texas Panhandle, scrubbing plans for a solar project amidst harsh backlash from local residents.
On Friday, Xcel Energy withdrew plans to build a $600 million solar project right outside of Rolling Hills, a small, relatively isolated residential neighborhood just north of the city of Amarillo, Texas. The project was part of several solar farms it had proposed to the Texas Public Utilities Commission to meet the load growth created by the state’s AI data center boom. As we’ve covered in The Fight, Texas should’ve been an easier place to do this, and there were few if any legal obstacles standing in the way of the project, dubbed Oneida 2. It was sited on private lands, and Texas counties lack the sort of authority to veto projects you’re used to seeing in, say, Ohio or California.
But a full-on revolt from homeowners and realtors apparently created a public relations crisis.
Mere weeks ago, shortly after word of the project made its way through the small community that is Rolling Hills, more than 60 complaints were filed to the Texas Public Utilities Commission in protest. When Xcel organized a public forum to try and educate the public about the project’s potential benefits, at least 150 residents turned out, overwhelmingly to oppose its construction. This led the Minnesota-based power company to say it would scrap the project entirely.
Xcel has tried to put a happy face on the situation. “We are grateful that so many people from the Rolling Hills neighborhood shared their concerns about this project because it gives us an opportunity to better serve our communities,” the company said in a statement to me. “Moving forward, we will ask for regulatory approval to build more generation sources to meet the needs of our growing economy, but we are taking the lessons from this project seriously.”
But what lessons, exactly, could Xcel have learned? What seems to have happened is that it simply tried to put a solar project in the wrong place, prizing convenience and proximity to an existing electrical grid over the risk of backlash in an area with a conservative, older population that is resistant to change.
Just ask John Coffee, one of the commissioners for Potter County, which includes Amarillo, Rolling Hills, and a lot of characteristically barren Texas landscape. As he told me over the phone this week, this solar farm would’ve been the first utility-scale project in the county. For years, he said, renewable energy developers have explored potentially building a project in the area. He’s entertained those conversations for two big reasons – the potential tax revenue benefits he’s seen elsewhere in Texas; and because ordinarily, a project like Oneida 2 would’ve been welcomed in any of the pockets of brush and plain where people don’t actually live.
“We’re struggling with tax rates and increases and stuff. In the proper location, it would be well-received,” he told me. “The issue is, it’s right next to a residential area.”
Indeed, Oneida 2 would’ve been smack dab up against Rolling Hills, occupying what project maps show would be the land surrounding the neighborhood’s southeast perimeter – truly the sort of encompassing adjacency that anti-solar advocates like to describe as a bogeyman.
Cotton also told me he wasn’t notified about the project’s existence until a few weeks ago, at the same time resident complaints began to reach a fever pitch. He recalled hearing from homeowners who were worried that they’d no longer be able to sell their properties. When I asked him if there was any data backing up the solar farm’s potential damage to home prices, he said he didn’t have hard numbers, but that the concerns he heard directly from the head of Amarillo’s Realtors Association should be evidence enough.
Many of the complaints against Oneida 2 were the sort of stuff we’re used to at The Fight, including fears of fires and stormwater runoff. But Cotton said it really boiled down to property values – and the likelihood that the solar farm would change the cultural fabric in Rolling Hills.
“This is a rural area. There are about 300 homes out there. Everybody sitting out there has half an acre, an acre, two acres, and they like to enjoy the quiet, look out their windows and doors, and see some distance,” he said.
Ironically, Cotton opposed the project on the urging of his constituents, but is now publicly asking Xcel to continue to develop solar in the county. “Hopefully they’ll look at other areas in Potter County,” he told me, adding that at least one resident has already come to him with potential properties the company could acquire. “We could really use the tax money from it. But you just can’t harm a community for tax dollars. That’s not what I’m about.”
I asked Xcel how all this happened and what their plans are next. A spokesperson repeatedly denied my requests to discuss Oneida 2 in any capacity. In a statement, the company told me it “will provide updates if the project is moved to another site,” and that “the company will continue to evaluate whether there is another location within Potter County, or elsewhere, to locate the solar project.”
Meanwhile, Amarillo may be about to welcome data center development because of course, and there’s speculation the first AI Stargate facility may be sited near Amarillo, as well.
City officials will decide in the coming weeks on whether to finalize a key water agreement with a 5,600-acre private “hypergrid” project from Fermi America, a new company cofounded by former Texas governor Rick Perry, says will provide upwards of 11 gigawatts to help fuel artificial intelligence services. Fermi claims that at least 1 gigawatt of power will be available by the end of next year – a lot of power.
The company promises that its “hypergrid” AI campus will use on-site gas and nuclear generation, as well as contracted gas and solar capacity. One thing’s for sure – it definitely won’t be benefiting from a large solar farm nearby anytime soon.
And more of the most important news about renewable projects fighting it out this week.
1. Racine County, Wisconsin – Microsoft is scrapping plans for a data center after fierce opposition from a host community in Wisconsin.
2. Rockingham County, Virginia – Another day, another chokepoint in Dominion Energy’s effort to build more solar energy to power surging load growth in the state, this time in the quaint town of Timberville.
3. Clark County, Ohio – This county is one step closer to its first utility-scale solar project, despite the local government restricting development of new projects.
4. Coles County, Illinois – Speaking of good news, this county reaffirmed the special use permit for Earthrise Energy’s Glacier Moraine solar project, rebuffing loud criticisms from surrounding households.
5. Lee County, Mississippi – It’s full steam ahead for the Jugfork solar project in Mississippi, a Competitive Power Ventures proposal that is expected to feed electricity to the Tennessee Valley Authority.
