We didn’t know it was coming. We didn’t know where it came from. We still can’t nail its climate change connection.

What happened?
No, seriously — what happened?
Last week, the American megalopolis, that string of jewels on the old Atlantic coast, found itself shrouded by wildfire smoke. New York City’s air turned ashen and dun, then glowed a supernatural amber. For the first time in who-knows, sightseers standing at the U.S. Capitol Building could not see the Washington Monument, a mile and change down the Mall.
You could list the sports games canceled or flights delayed, but what was oddest about the event was the sheer ubiquity of it. This was one of the few news stories I can remember where you could look up from whatever article you were reading and see the story itself, softly lapping at your window.
And then it was gone. By Friday, the haze had blown out to sea.
It was, in retrospect, a strange time — deeply strange, humblingly strange, strange before almost any other quality. More than 128 million Americans were under an air-quality alert on Wednesday night — roughly the population of Germany and Spain combined — but scarcely 36 hours earlier, nobody had known to prepare for anything worse than a moderate haze. The country’s biggest wildfire-pollution event on record arrived essentially out of nowhere.

One of the main modes of journalism today — but also, frankly, one of the main frames of our whole cultural apparatus, from TikToks that lightly gloss Wikipedia articles to rampant right-wing conspiracism — is that of the explanation. Everyone explains what’s happening to each other, as it happens, at all times, and therefore makes the world seem rational, empirical, and less frightening. Yet with the wildfire smoke, what is so striking is how little we understood. Nearly every important step in the story was misapprehended as it happened.
We didn’t know that the smoke was coming, for instance. On Tuesday morning, meteorologists predicted that the same moderate haze that has hung around all season would again hit the East Coast. The New York Department of Environmental Conservation put out an alert saying that the air quality index, or AQI, might rise to 150 across the state.
They did not forecast — nobody, as far as I can tell, did — that the worst air pollution in decades would soon wallop the state. By Tuesday night, New York City’s AQI had already reached 174, according to Environmental Protection Agency data. As I walked home in D.C., I could see tendrils of visible smoke hugging the upper stories of apartment buildings.
This prediction failure gave the ensuing response a halting, confused quality. How could such a massive event come out of nowhere? Not until Thursday afternoon — when the smoke had nearly passed — did the federal government advise its workers that they could telework or take vacation time to avoid the bad air. On Friday, New York closed in-person schools, just in time for blue sky to return.
I find it hard to blame them. This was an unprecedented event in part because the fires were so far from where they affected. Everyone had seen the videos of smoke besieging Portland and San Francisco in 2020, but back then, the fires had been near those cities — a couple hundred miles away at most. Where was the smoke coming from now? The Adirondacks were fine. Vermont was’t burning.
Here, we misunderstood again. Many outlets — including this one, at first — initially reported that the smoke came from Nova Scotia, where large and destructive fires had raged the week before. But those fires had been doused over the weekend by some of the same weather pattern that was now ferrying smoke to us. In fact, the smoke had come from the boreal forests of northern Quebec, more than 500 miles from New York City.
Why were these fires raging? Not even Canadians could give a good answer. With fires in Alberta and Nova Scotia gobbling attention and resources, the Quebec fires had seemingly been an afterthought until their smoke blew into Toronto and Ottawa, which happened only a few hours before it arrived in New York. Suddenly, a secondary event had become the main event.
On Wednesday, I talked to a Canadian climatologist who seemed hazy about why Quebec was burning in the first place. “I think this situation is kind of similar to Nova Scotia,” he told me, blaming that province’s warm, dry spring for the blazes. But this explanation — which appeared in many outlets — was only somewhat true: While Quebec had suffered a warm May, it was not in drought.
We did not understand why these fires are burning — and honestly, we still don’t. President Joe Biden said that the smoke provided “another stark reminder of the impacts of climate change.” I am not so sure. There’s no doubt, to be clear, that climate change will make wildfires worse across North America: The Intergovernmental Panel on Climate Change says that hot, dry “fire weather” will increase throughout the 21st century. But, again, Quebec is not in drought. As for today, no climate-change signal has appeared in eastern Canadian wildfire data. Their connection to climate change is far less clear cut than it is in, say, California’s blazes.
Yet neither would I condescend to someone who does blame climate change here. When something like this happens, how can you not cite the planet’s biggest ongoing physical transformation? If climate change makes flukey weather more likely, shouldn’t we at least consider it being responsible for some of the flukiest weather in decades? The thing about unprecedented events is that you lack precedent for them.
Not that we completely lack an example for this. In 1780, the sun was blotted out across New England. Nocturnal animals came out; people fretted in the streets and abandoned their work; the Connecticut state legislature considered adjourning for doomsday. Not until a decade ago did we finally learn that the “dark day” was caused by Canadian wildfire smoke drifting south.
Which suggests that this might be a once-in-250-year event. But maybe it’s not any more. Maybe with climate change, it’s a once-a-century event. Or a once-in-a-decade event. For now, the sample size is two.
So I wonder: If it wasn’t climate change, would it matter? The pandemic has already taught us that indoor air quality matters, that unseen particles floating in the air can do serious harm. No matter what happens with the climate, Canada is too large and unpopulated to fight every wildfire; neither can it manage the same kind of labor-intensive forest management that California might attempt. East Coasters should come away from our own dark days with new compassion for people out West — and those across the world — who must deal with wildfire smoke on a seasonal basis, not to mention the fires themselves. Regardless of climate change’s role in this fire, it makes wildfires more likely: We should continue to try to decarbonize as fast as we can.
But as for local policy, perhaps our aims should be humbler. We now know (again) that a great cloud of wildfire smoke can blow up on the East Coast at any moment and poison our air. We don’t need to know everything to protect ourselves and our neighbors from that. Air filters cost hundreds of dollars, but not thousands; in new multi-family buildings, they are built into the ventilation system itself. Perhaps the right lesson from this outbreak should be to change our expectations, and think of indoor air filtering like brushing your teeth — a habit essential to our hygiene, to be used by all, and to be provisioned for those who cannot afford one at the public expense.
Maybe that’s prudent climate adaptation. Or maybe — in the wake of COVID, Canadian smoke, and who-knows-what-comes-next — it’s just new common sense.

According to a new analysis shared exclusively with Heatmap, coal’s equipment-related outage rate is about twice as high as wind’s.
The Trump administration wants “beautiful clean coal” to return to its place of pride on the electric grid because, it says, wind and solar are just too unreliable. “If we want to keep the lights on and prevent blackouts from happening, then we need to keep our coal plants running. Affordable, reliable and secure energy sources are common sense,” Chris Wright said on X in July, in what has become a steady drumbeat from the administration that has sought to subsidize coal and put a regulatory straitjacket around solar and (especially) wind.
This has meant real money spent in support of existing coal plants. The administration’s emergency order to keep Michigan’s J.H. Campbell coal plant open (“to secure grid reliability”), for example, has cost ratepayers served by Michigan utility Consumers Energy some $80 million all on its own.
But … how reliable is coal, actually? According to an analysis by the Environmental Defense Fund of data from the North American Electric Reliability Corporation, a nonprofit that oversees reliability standards for the grid, coal has the highest “equipment-related outage rate” — essentially, the percentage of time a generator isn’t working because of some kind of mechanical or other issue related to its physical structure — among coal, hydropower, natural gas, nuclear, and wind. Coal’s outage rate was over 12%. Wind’s was about 6.6%.
“When EDF’s team isolated just equipment-related outages, wind energy proved far more reliable than coal, which had the highest outage rate of any source NERC tracks,” EDF told me in an emailed statement.
Coal’s reliability has, in fact, been decreasing, Oliver Chapman, a research analyst at EDF, told me.
NERC has attributed this falling reliability to the changing role of coal in the energy system. Reliability “negatively correlates most strongly to capacity factor,” or how often the plant is running compared to its peak capacity. The data also “aligns with industry statements indicating that reduced investment in maintenance and abnormal cycling that are being adopted primarily in response to rapid changes in the resource mix are negatively impacting baseload coal unit performance.” In other words, coal is struggling to keep up with its changing role in the energy system. That’s due not just to the growth of solar and wind energy, which are inherently (but predictably) variable, but also to natural gas’s increasing prominence on the grid.
“When coal plants are having to be a bit more varied in their generation, we're seeing that wear and tear of those plants is increasing,” Chapman said. “The assumption is that that's only going to go up in future years.”
The issue for any plan to revitalize the coal industry, Chapman told me, is that the forces driving coal into this secondary role — namely the economics of running aging plants compared to natural gas and renewables — do not seem likely to reverse themselves any time soon.
Coal has been “sort of continuously pushed a bit more to the sidelines by renewables and natural gas being cheaper sources for utilities to generate their power. This increased marginalization is going to continue to lead to greater wear and tear on these plants,” Chapman said.
But with electricity demand increasing across the country, coal is being forced into a role that it might not be able to easily — or affordably — play, all while leading to more emissions of sulfur dioxide, nitrogen oxide, particulate matter, mercury, and, of course, carbon dioxide.
The coal system has been beset by a number of high-profile outages recently, including at the largest new coal plant in the country, Sandy Creek in Texas, which could be offline until early 2027, according to the Texas energy market ERCOT and the Institute for Energy Economics and Financial Analysis.
In at least one case, coal’s reliability issues were cited as a reason to keep another coal generating unit open past its planned retirement date.
Last month, Colorado Representative Will Hurd wrote a letter to the Department of Energy asking for emergency action to keep Unit 2 of the Comanche coal plant in Pueblo, Colorado open past its scheduled retirement at the end of his year. Hurd cited “mechanical and regulatory constraints” for the larger Unit 3 as a justification for keeping Unit 2 open, to fill in the generation gap left by the larger unit. In a filing by Xcel and several Colorado state energy officials also requesting delaying the retirement of Unit 2, they disclosed that the larger Unit 3 “experienced an unplanned outage and is offline through at least June 2026.”
Reliability issues aside, high electricity demand may turn into short-term profits at all levels of the coal industry, from the miners to the power plants.
At the same time the Trump administration is pushing coal plants to stay open past their scheduled retirement, the Energy Information Administration is forecasting that natural gas prices will continue to rise, which could lead to increased use of coal for electricity generation. The EIA forecasts that the 2025 average price of natural gas for power plants will rise 37% from 2024 levels.
Analysts at S&P Global Commodity Insights project “a continued rebound in thermal coal consumption throughout 2026 as thermal coal prices remain competitive with short-term natural gas prices encouraging gas-to-coal switching,” S&P coal analyst Wendy Schallom told me in an email.
“Stronger power demand, rising natural gas prices, delayed coal retirements, stockpiles trending lower, and strong thermal coal exports are vital to U.S. coal revival in 2025 and 2026.”
And we’re all going to be paying the price.
Rural Marylanders have asked for the president’s help to oppose the data center-related development — but so far they haven’t gotten it.
A transmission line in Maryland is pitting rural conservatives against Big Tech in a way that highlights the growing political sensitivities of the data center backlash. Opponents of the project want President Trump to intervene, but they’re worried he’ll ignore them — or even side with the data center developers.
The Piedmont Reliability Project would connect the Peach Bottom nuclear plant in southern Pennsylvania to electricity customers in northern Virginia, i.e.data centers, most likely. To get from A to B, the power line would have to criss-cross agricultural lands between Baltimore, Maryland and the Washington D.C. area.
As we chronicle time and time again in The Fight, residents in farming communities are fighting back aggressively – protesting, petitioning, suing and yelling loudly. Things have gotten so tense that some are refusing to let representatives for Piedmont’s developer, PSEG, onto their properties, and a court battle is currently underway over giving the company federal marshal protection amid threats from landowners.
Exacerbating the situation is a quirk we don’t often deal with in The Fight. Unlike energy generation projects, which are usually subject to local review, transmission sits entirely under the purview of Maryland’s Public Service Commission, a five-member board consisting entirely of Democrats appointed by current Governor Wes Moore – a rumored candidate for the 2028 Democratic presidential nomination. It’s going to be months before the PSC formally considers the Piedmont project, and it likely won’t issue a decision until 2027 – a date convenient for Moore, as it’s right after he’s up for re-election. Moore last month expressed “concerns” about the project’s development process, but has brushed aside calls to take a personal position on whether it should ultimately be built.
Enter a potential Trump card that could force Moore’s hand. In early October, commissioners and state legislators representing Carroll County – one of the farm-heavy counties in Piedmont’s path – sent Trump a letter requesting that he intervene in the case before the commission. The letter followed previous examples of Trump coming in to kill planned projects, including the Grain Belt Express transmission line and a Tennessee Valley Authority gas plant in Tennessee that was relocated after lobbying from a country rock musician.
One of the letter’s lead signatories was Kenneth Kiler, president of the Carroll County Board of Commissioners, who told me this lobbying effort will soon expand beyond Trump to the Agriculture and Energy Departments. He’s hoping regulators weigh in before PJM, the regional grid operator overseeing Mid-Atlantic states. “We’re hoping they go to PJM and say, ‘You’re supposed to be managing the grid, and if you were properly managing the grid you wouldn’t need to build a transmission line through a state you’re not giving power to.’”
Part of the reason why these efforts are expanding, though, is that it’s been more than a month since they sent their letter, and they’ve heard nothing but radio silence from the White House.
“My worry is that I think President Trump likes and sees the need for data centers. They take a lot of water and a lot of electric [power],” Kiler, a Republican, told me in an interview. “He’s conservative, he values property rights, but I’m not sure that he’s not wanting data centers so badly that he feels this request is justified.”
Kiler told me the plan to kill the transmission line centers hinges on delaying development long enough that interest rates, inflation and rising demand for electricity make it too painful and inconvenient to build it through his resentful community. It’s easy to believe the federal government flexing its muscle here would help with that, either by drawing out the decision-making or employing some other as yet unforeseen stall tactic. “That’s why we’re doing this second letter to the Secretary of Agriculture and Secretary of Energy asking them for help. I think they may be more sympathetic than the president,” Kiler said.
At the moment, Kiler thinks the odds of Piedmont’s construction come down to a coin flip – 50-50. “They’re running straight through us for data centers. We want this project stopped, and we’ll fight as well as we can, but it just seems like ultimately they’re going to do it,” he confessed to me.
Thus is the predicament of the rural Marylander. On the one hand, Kiler’s situation represents a great opportunity for a GOP president to come in and stand with his base against a would-be presidential candidate. On the other, data center development and artificial intelligence represent one of the president’s few economic bright spots, and he has dedicated copious policy attention to expanding growth in this precise avenue of the tech sector. It’s hard to imagine something less “energy dominance” than killing a transmission line.
The White House did not respond to a request for comment.
Plus more of the week’s most important fights around renewable energy.
1. Wayne County, Nebraska – The Trump administration fined Orsted during the government shutdown for allegedly killing bald eagles at two of its wind projects, the first indications of financial penalties for energy companies under Trump’s wind industry crackdown.
2. Ocean County, New Jersey – Speaking of wind, I broke news earlier this week that one of the nation’s largest renewable energy projects is now deceased: the Leading Light offshore wind project.
3. Dane County, Wisconsin – The fight over a ginormous data center development out here is turning into perhaps one of the nation’s most important local conflicts over AI and land use.
4. Hardeman County, Texas – It’s not all bad news today for renewable energy – because it never really is.
