The eastern and northern United States are suffering under a hazy, poisonous cloud of wildfire smoke, produced by out-of-control forest fires in Quebec and Nova Scotia. The most toxic soot and ash are sitting virtually on top of North America’s most densely populated corridor, clouding the air in New York City; Toronto; Ottawa; Philadelphia, Washington, D.C.; and Norfolk, Virginia.
Air pollution alerts are in effect across the United States and Canada, affecting roughly 150 million people.
This is Heatmap’s set of commonly asked questions about the crisis. We’ll keep it updated throughout the event.
Hundreds of wildfires have raged across northern Quebec for the past few weeks, driven by unusually warm and dry conditions.
Then on Monday, a low-pressure system surrounded by counterclockwise winds moved just off New England’s coast. Its strong, dry gusts fanned the flames in Canada, then pushed the resulting smoke and ash into the eastern United States.
Intense Canadian fires are unusual this early in the season, but the fires this year were fed by a warm spring and drought-like condition, Kent Moore, an atmospheric-physics professor at the University of Toronto, told me. Because the fires took hold before the vegetation could “green up” for the spring, the conflagrations grew more rapidly than they normally would, he said.
The dry conditions also helped the fires ignite the soil itself. “Because the soil was so dry — because of the dry winter and the dry spring — the fire got into the ground,” he said. “The vegetation below ground started to burn, and those are much harder to put out.”
This is likely one of America’s worst days for air pollution in several decades, in terms of the number of people affected and the severity of the exposure, Marshall Burke, an economist and sustainability professor at Stanford, told me.
“It’s pretty off the chart,” Burke said. Wildfire smoke is affecting New York City much more acutely — and much earlier in the year — than it has at any time since 2006, when contemporary air-pollution data began to be kept.
It is difficult to attribute a single unprecedented event to climate change, and the climatology of wildfires in eastern North America is particularly challenging. (Climate change has more clearly worsened wildfires out West.) “This is probably an unlucky year for Canada, as far as wildfires go,” Moore, the atmospheric physicist, said.
But wildfires will become more likely across Canada as the climate changes, he said. And while climate change should broadly increase rainfall across Canada, it will also increase the likelihood of heat waves and more extreme spring and summer temperatures, which can make wildfires more likely.
“Nova Scotia has always had wildfires. It’s just they’ve had more wildfires this year than they have on average for the whole year,” he said. “There’s always going to be wildfires, but there’s going to be more of them.” As Canadian cities sprawl into previously uninhabited woodland areas, he added, the human impacts of wildfires will increase — even if the number and intensity of wildfires does not.
First, consult the air quality index at AirNow.gov. The AQI is a unit-less index of air quality running from zero to 500; any reading above 100 would rank as unusually polluted in the United States. On Wednesday afternoon, some air sensors in New York and New Jersey indicated that the AQI exceeded 400.
If it’s higher than 100, then the most vulnerable groups of people — including children, the elderly, anyone with a cardiopulmonary condition, and pregnant women — should limit strenuous activity outdoors. If higher than 150, then people should generally try to limit their outdoor activity; at levels above 200, the air is considered unhealthy and everyone should try to go outside as little as possible.
If you think you might be especially vulnerable, err on the side of caution. Recently, a body of new and large-scale studies have shown that air pollution is generally worse for the body and brain than previously thought.
Then, if you’re in an area with hazardous air pollution, consider how to limit your exposure to the air as much as possible. Keep your doors and windows closed. An air filter outfitted with a HEPA filter can improve the air in a home or apartment. It should generally be closer to the most sensitive people.
“Any pregnant moms — if my wife or anyone I knew was pregnant right now — I would be texting them to stay inside and sit by an air filter,” Burke told me. Exposure to severe air pollution during pregnancy has been shown to increase the risk of preterm birth, and it can reduce a child’s lifelong earnings, cognitive performance, and other indicators, he said.
A KN95 or N95 mask — the type of high-filtration mask used to prevent COVID infection — can also significantly limit your exposure to soot and ash. If you are in a sensitive group or are worried about air pollution’s health effects, you could consider wearing a mask inside if you have no other way to filter the air.

A new study suggests skeptical voters don’t respond to such urgent language — while climate-concerned voters find it depressing.
This is an edition of Heatmap Daily, a digest from our executive editor that comes out every weekday. Subscribe to this newsletter here.
We have a fascinating new project to share with you today. It gets to the heart of the question: Is there anything that can make Americans care about climate change right now?
Starting last year, Heatmap commissioned Embold Research to study what U.S. voters currently think about climate change — what messages are connecting with Americans today and which ones are falling flat.
It’s out now. I wasn’t directly involved in this research — other members of our team led it — but I think the results are interesting, useful, and worth your attention. (Embold Research is a frequent research partner of ours, too: They conduct our data center polling.)
The report divvied the electorate into three buckets — registered voters who are already persuaded about climate change, those who are persuadable, and skeptics who are less likely to be convinced — and examines what they believe about politics, major political issues, energy, and the environment.
In the study’s first phase, for instance, we asked more than 2,100 Americans to rank 11 different issues in their relative importance. Just over 50% of Americans think climate change is “very” or “extremely important” — and while that may sound encouraging, it actually means that climate change ranked last among the 11 issues we tested.
“The environment” ranks much higher among the three cohorts, with 70% of Americans considering it at least “very” important. The economy, jobs, inflation, and the cost of living dominate voter concerns.
What’s interesting, though, is that these questions of issue importance reverse among the group of “persuaded” Americans. This group believes climate change to be among the most dire problems facing the United States. They’re concerned about the economy too, to be clear — but they also rank healthcare costs, the environment, and threats to democracy more highly than other groups. (Perhaps unsurprisingly, this group identifies overwhelmingly as Democrats.)
My colleague Jeva Lange has more on another finding from the research: why voters don’t believe politicians when they say clean energy is the cheapest form of energy available. You should read her story — but before we go, I want to highlight one more finding from the study.
In the study’s second phase, Embold Research called back 15 of the respondents from the first poll and interviewed them about their beliefs and what political messages they responded well to. Then it surveyed a new sample of more than 2,100 Americans, using lessons from the interviews to inform their questions.
One lesson from those phases: Calling climate change a “crisis” or “catastrophe” fell flat among voters — but for different reasons among each cohort.
For voters who are already persuaded about climate change’s dangers, the framing is demotivating. Those people are already worried about climate change, and so hearing that more informed advocates are worried about a climate “crisis” or “catastrophe” just makes them more numb and depressed.
Skeptics, meanwhile, think the language is meant to manipulate them. And for voters who could be persuaded about climate change, talk of a “crisis” conflicts with their observation of gradual change and punctuated equilibrium.
That message sits at odds with how Democratic politicians and issue advocates talked about climate change in the first few years of this decade, obviously. And it points to another interesting finding: Even when American voters are skeptical of climate change as an issue area, they still generally care about the environment.

New polling by Heatmap and Embold Research shows where one of climate advocates’ favorite arguments for renewables is falling short.
It’s the million-dollar question of clean energy advocacy: How do you persuade climate change skeptics to love renewables?
For years, the clean energy industry has treated the fact that renewables are the cheapest form of new electricity as its messaging trump card. This argument has the advantage of being true. Yes, there is nuance, room for debate, and always the possibility that things could change dramatically in the future. But this summer, the investment bank Lazard reconfirmed what the Lawrence Berkeley National Laboratory and the International Renewable Energy Agency — and plenty of other independent analyses — had found before it: that wind and solar energy are, on the whole, cheaper than fossil fuels.
And yet according to new polling and focus group conversations conducted by Heatmap News and Embold Research, the affordability argument barely moves the needle for the segment of the American public that most needs convincing. More than two-thirds (78%) of voters who are “doubtful” or “dismissive” of climate change — a population segment described by the Yale Program on Climate Communications and that we have labeled as “skeptics” — told us they believe that advocates for wind and solar energy exaggerate how cheap the sources have become (a mere 17% disagreed).
Even for those in the middle who are “persuadable” on climate change (as opposed to the “persuadeds,” who describe themselves as “alarmed” about it), an affordability argument doesn’t land cleanly — 62% believed the claims are exaggerated compared to 24%. In fact, a majority of all voters — 55% — told us that wind and solar are only cost-competitive with oil and gas because of subsidies, even as 75% acknowledge that oil and gas companies get government help lowering costs, too.
Inflation Reduction Act postmortems have a tendency to hand-wring about the Biden administration and its proxies’ lack of success pitching the affordability angle to the American public. Our polling backed up some of this. The pervasive conviction seems to be that the economic upsides of renewable energy aren’t real: 57% of all voters (and 78% of the subset of climate change skeptics) said clean energy advocates exaggerate how cheap wind and solar have become.
But as clean energy advocates look ahead to what to try the next time, our polling offers a cautionary note: The messenger, not just the message, needs a tweak. Independent scientists and researchers were the only group trusted by a majority of voters (63%), and even then, skeptics remained difficult to break through with, as less than a third putting their trust in any messenger at all.
If there’s a bright spot in our polling, it’s that attacks on clean energy have also apparently failed to gain traction. When we asked voters in a separate poll what they think is driving their bills higher, clean energy was among the least identified factors. Just 31% of voters blamed the renewable energy industry, compared with 58% who picked out new data center construction, 55% for the oil and gas industry, 52% for the aging electrical grid, and 48% for rising electricity demand. Our polling appears to describe, then, an electorate that doesn’t blame clean energy for raising electricity bills, but also doesn’t buy the messaging that it could help bring them down.
Breaking through with skeptics and persuadables is obviously the key for turning public opinion in favor of clean energy. In pursuit of that goal, Embold conducted interviews with voters to better understand where the potential openings might be for clean energy messaging to break through — and to identify the kind of language that might hamper that goal. But even after synthesizing the findings and crafting a political message designed to appeal to skeptics’ concerns — one that highlighted the falling cost of renewable electricity alongside arguments about energy security and job creation — a mere 7% of skeptics found it “extremely believable.” “Without my tax dollars, [renewables are] too expensive,” one Trump voter told us. “It will all be in a landfill in 20 years!” (Note that “skeptics” isn’t a political designation, although 89% of them told us they voted for President Trump in the last election.)
Heatmap’s polling offered a more pessimistic view of the electorate compared to comparable polling by other groups, which have found that messages about bringing down electricity bills via increasing clean energy resonate across the broad political spectrum. “We obviously do a fair amount of phone polling, and we’ve been surprised how positive people have been on clean energy and how much they see it as a central part of the solution to the energy affordability crisis that everybody is feeling,” Jesse Lee, a senior advisor at the advocacy and communications organization Climate Power, told me. (Climate Power’s poll notably looks at the whole electorate — skeptics, persuadables, and persuadeds alike — rather than segmenting their findings for more specific messaging purposes.) “But,” he agreed, “certainly there are holdouts.”
Just 20% of the skeptics Embold surveyed, for instance, told us that seeing a comparison of what families saved on their electricity bills after installing rooftop solar would improve their opinion of the technology’s affordability — and 54% said nothing could convince them that solar was affordable. A full 75% of skeptics also agreed with the statement that clean energy technologies such as rooftop solar, electric heat pumps, and electric vehicles have a high enough upfront cost that the savings over time wouldn’t be “worth it.” When asked about utility-scale generation, skeptics viewed nuclear, coal, and natural gas as the least expensive options, with wind being the most expensive, followed by solar.
I asked Lee at Climate Power if he thinks it’s worth trying to reach these entrenched climate skeptics, who make up 22% of the electorate according to our polling. “To the extent that there are limited resources, that’s probably not where you spend all your time,” he said. “You shoot for people that are at least a little bit open to it — but who might be the neighbors of [the skeptics],” he said.
“If that neighbor gets solar panels on their roof, and suddenly they’re walking around the neighborhood telling people their electricity bill was $0 last month, that’s going to have a lot more effect on a person who’s entrenched than hearing a political message from a political group,” Lee went on.
Among people who said they don’t have or can’t afford solar, just 28% told us that “seeing data showing how much money families save on their electricity bills” with solar would help convince them on its affordability. That beat out tax credits (24%), lower upfront costs (23%), financing options (19%) — and yes, “hearing about a neighbor or friend who saved money after getting solar,” which only 12% of people said might change their minds. And though only 20% of skeptics said being shown bill data would change their opinion, bill data was also the only messaging approach that ranked at or near the top of all groups alike.
Unsurprisingly, the “persuadables” group turned out to be more responsive on the question of whether clean energy is affordable. More than a quarter (27%) were receptive to bill savings data, and 60% said they trusted scientists as messengers. But crafting that message is still an uphill battle with the demographic: When Embold tailored a statement intended to move the group, fewer than three in 10 actually found it convincing.
Winning on messaging about clean energy affordability, then, is far more complicated than simply laying out facts and comparisons of renewables in a speech or advertisement. Being asked the question in a poll is not the same as a real-world test case, of course, but, but the wrong messenger risks alienating the people who most need to be convinced, our research shows. Proof needs to be local and tailored — perhaps an impossible ask of a national or even state-level general campaign.
Cost, as a message, is still a winner, in other words. But the window for communicating on it is far narrower than many advocates likely realize. As one 2024 third-party voter told us after reading Embold’s three tailored messages on clean energy, “I don’t really like any of them. They all seem to just be telling me the ‘truth,’ but I don’t know the truth without evidence.”

On solar manufacturing, New England gas, and Pacific Northwest geothermal
Current conditions: The Pacific just can’t catch a break this hurricane season as forecasters warn that a new tropical development called Invest 96E could form in the next two days off Baja California, right behind Hurricane Lowell • In Indonesia, the wildfires blazing through the peatlands and forests of Borneo and Sumatra are now emitting by far the most carbon dioxide of any blazes in the world • A late-summer heat wave is sending temperatures along the California coastline beyond 100 degrees Fahrenheit this week.
When Alphabet inked its first nuclear deal in 2024, the Google parent company opted to back a next-generation, fluoride salt-cooled reactor startup called Kairos Power. Six months later, the tech behemoth contracted Elementl Power, a nuclear project developer that works with all kinds of reactors, to scout locations for deploying novel atomic technologies. Last October, Google broadened its approach to focus on large-scale reactors that either already existed or were under development. The company eyed financing the construction of the abandoned Westinghouse AP1000s planned for the V.C. Summer plant in South Carolina before the project went under nearly a decade ago. Then Google and NextEra began laying the groundwork to restart the Duane Arnold nuclear station, Iowa’s only such plant, which shut down in 2020. As I told you on Tuesday, that latter deal took a major step forward when the Department of Energy pledged $1.9 billion toward bringing the single 615-megawatt reactor back online.
Now Google is exporting its strategy to Europe. On Wednesday, the giant announced a 22-year power purchase agreement with the Finnish utility Fortum Oyj to extend the life of the Loviisa nuclear station by buying as much as 50% of its electricity from 2030 to 2049. The contract — the first of its kind in Europe to provide for direct power purchases between a specific power plant and a hyperscaler — starts in 2028.
The deal is part of a broader $15.1 billion investment into artificial intelligence infrastructure throughout Finland over the next two years, and will direct roughly $1.1 billion toward the plant’s relicensing. “Long-term partnerships like the one between Fortum and Google are essential to making that happen, especially in today’s uncertain market environment characterized by low visibility and highly volatile electricity prices,” Fortum CEO Markus Rauramo said in a statement. In a text message last night, Emmet Penney, the director of energy and infrastructure at the Foundation for American Innovation, told me it was once “fashionable to say that nuclear was dead in the West, that we could only look on as nuclear slouched toward its demise and irrelevance.” Now, however, “Google is doing the world a favor by showing why and how that view was wrong” by demonstrating willingness to put its money where its mouth is to expand the power supply, he said. “Some things are fads, but nuclear is never out of season.”
Global investments in manufacturing clean technology fell 14% in the first quarter of 2026 and another 7% in the second three-month window, according to an analysis by the Rhodium Group’s Clean Investment Monitor released Thursday of the first half of this year. For the first time, China’s share of green manufacturing investments dipped below a third, marking a significant decline from its peak of over 71% in 2023. A major drop in the expansion of solar panel factories accounted for much of the slowdown. Investments in new factories fell by 83% in the second quarter of 2026 compared to the peak in the last three months of 2023. China accounted for 94% of the decline. But China’s contraction came with expansion elsewhere. India, for example, saw solar factory investments accelerate from 5% to 48%, making it the largest net contributor for the past four quarters. Solar manufacturing is expanding in the U.S., and the Department of Commerce’s new import duties on the polysilicon needed to make most panel components should help that continue. But the overall picture for clean energy investment, as my colleague Emily Pontecorvo described in the spring, is mixed.
There are green shoots, however. While the amount of capital spent on construction of new manufacturing and industrial plants slowed, the value of such investments rose 10% in the first quarter of this year and held steady in the second quarter, breaking a 10-quarter streak of declines in announced investments. The bulk of the deals were in critical minerals, wind, sustainable aviation fuel, batteries, and — yes — solar. But there’s also more coal. On Thursday morning, the International Energy Agency forecast global coal demand to reach a record high of nearly 9 billion metric tons this year.
The U.S. has enough solar panels in operation today to power more than 50 million American homes, representing over a third of households. That’s according to the latest market analysis conducted by the consultancy Wood Mackenzie on behalf of the Solar Energy Industries Association and released early this morning. Solar developers added 11.4 gigawatts of generating capacity in the second quarter of 2026, a 45% increase from the same period last year and 43% increase from the first three months of this year. Most of that new capacity came from utility-scale projects, which added 9.6 gigawatts — a 61% year-over-year leap. “Solar and storage have grown to a scale most Americans have yet to fully realize and we simply can’t meet America’s growing energy needs without these technologies,” Tim Pawlenty, the chief executive of the solar industry’s leading trade group, said in a statement.
It’s a milestone for solar’s expansion, and highlights the competitiveness of the technology despite the Trump administration’s crackdown on renewables it criticizes as too weather dependent. But it’s only a description of capacity. It’s virtually impossible for all the solar panels in the country to produce power at the same time, and the swings in electricity production are ultimately what draw criticism from those who instead push for generating stations that can pump out power at all times of day. That, in my view, makes the most important signal in the report the speed of the growth, demonstrating how quickly solar can come online and serve surging demand.

Yesterday I told you that a federal court overturned the water permits New Jersey issued for construction of a pipeline to carry more natural gas into the Northeast, delivering a blow to the pipeline push the region is gearing up for as winter energy demands increasingly become what my colleague Matthew Zeitlin described bluntly last year as “a problem.” But there’s some good news, via the latest analysis from the U.S. Energy Information Administration. Enough cheap gas is flowing into New England at a moment when consumption is relatively low to push down prices. Natural gas prices at Algonquin Citygate, a trading and pricing hub in Boston that averages out what New England is paying for the fuel, are now trading at a discount compared to the main U.S. benchmark, the Henry Hub. Prices at Algonquin Citygate averaged 43 cents per million British thermal units less than Henry Hub from April through July. Part of the price drop came from a drop in demand as home heating fell off during the summer and solar generation increased during longer sunny days. Increased supply from Appalachia was another factor, as was a spike in imports from Canada.
Emissions of greenhouse gases from fossil fuels and agriculture are widely recognized as the primary drivers behind rising global temperatures. But scientists have long warned that, as the planet grows hotter, natural feedback loops will begin to pump more emissions into the atmosphere, from methane seeping out from decaying ancient material in thawing permafrost or carbon dioxide spewing from infernos like those scorching Indonesia’s biggest islands. A new study suggests that those warming-induced greenhouse gases from natural sources could amplify global warming by 20% to 30% this century, adding as much 0.4 degrees Celsius to the global temperature average. The authors of the study, published early Thursday morning in the journal Environmental Research Letters, billed it as the largest effort to date to quantify the combined impact of carbon dioxide and methane from permafrost thaw, wildfires, wetlands, and inland waterways. Permafrost thaw, however, comprises roughly half the projected emissions. The authors came from Stanford University, Woodwell Climate Research Center, research nonprofit Spark Climate Solutions, and the advocacy group Environmental Defense Fund. Even if emissions from human activities reached net zero, greenhouse gases could create feedback loops that raise global temperatures by at least 0.2 degrees Celsius by 2100. A higher emissions scenario could be twice that much warming.
“The results are a wake-up call, and it’s imperative that they be included in the next generation of climate policies,” Robert Jackson, the Stanford University professor and chair of the Global Carbon Project who co-authored the paper, said in a statement.
The Pacific Northwest is poised for a big geothermal push. Hexagon Energy, an independent energy developer, and timber and wood giant Weyerhaeuser Company just inked a strategic partnership that will clear the way for geothermal projects across the latter company’s vast property portfolio in Oregon and Washington. “Geothermal energy represents an emerging opportunity to provide clean and reliable, around-the-clock power, and our ownership presents a unique platform to evaluate that potential in the Pacific Northwest,” Kendall Fountain, Weyerhaeuser’s vice president of energy and natural resources, said in a statement. Once built, the projects are expected to generate up to 3 gigawatts of power.
