First it hit Chicago and Milwaukee. Then Detroit, Cleveland, and Washington, D.C. Now it’s back in New York.
Smoke from far-north wildfires returned to the United States and Canada this week, canceling concerts and summer camps, and sending up “Code Red” air-quality alerts across the continent. On Friday, four of the five cities with the world’s worst air pollution were in eastern North America.
The wildfire smoke’s return raised the specter of a long, hot, smoky summer. When wildfire smoke first smothered the East Coast in early June, the fluorescent sky seemed almost like a curiosity. Historians had to go back centuries — to New England’s “Dark Day” of 1780 — to find an appropriate comparison.
Now, they only need to remember a few weeks earlier. Much like how the successive waves of COVID-19, once a terrifying and confusing new reality, slowly became a tedious (but no less dangerous) fact of life, the wildfire smoke has become — and will probably remain — a part of the East Coast’s summer.
Pending a meteorological surprise, the wildfire smoke is likely to return periodically throughout the rest of the summer. The smoke probably won’t fully go away until late September or early October, when Quebec’s fire season ends.
“A lot of the wildfires are in western Quebec, right near Hudson Bay. About 34 wildfires have been left completely to burn,” Matthew Capucci, a Washington, D.C.-based meteorologist, told me. Recent weather patterns have been so dry — and there’s so little rain on the horizon — that almost nothing suggests those fires are likely to go out any time soon, he said.
“Nothing’s gonna put the fires out. They’re gonna keep burning,” he said. The first real break in the pattern is likely to come with the return of hard snowfall and cold weather in three or four months. Until then, every northwest wind will bring clouds of smoke to the eastern United States and Canada.

That is despite any fire-fighting that Canada can manage, Michael Wara, a senior researcher at the Stanford Woods Institute for the Environment, told me.
For now, hundreds of American firefighters are essentially on loan to the Canadian government’s firefighting effort. America can spare those hotshot crews because few wildfires are raging in the Lower 48. But as fire season heats up south of the border, those firefighters will have to return home, and Canada will have fewer resources with which to battle the flames.
The location of the fires also makes them particularly tricky to fight. Many of the blazes are in remote, unpopulated stretches of boreal forest. Almost no roads exist to carry crews close to the blaze; few airfields, if any, are close enough — or large enough — to allow federal air tankers to operate in the area and drop flame retardant.
“To understand the landscape, go watch an episode of Alone,” Wara said, alluding to the History Channel reality show where 10 people must each survive by themselves in the remote Canadian wilderness for months at a time. “That’s what we’re talking about here.”
This is the worst Canadian wildfire year on record. More than 29,500 square miles of forest have burned, an area larger than the state of West Virginia. In 1989, when the previous wildfire record was set, it took 12 months for that much forest to burn. But this year has already surpassed the old record in barely more than six.
Climate change has warmed the Canadian boreal forest faster than almost anywhere else in the world. The biome’s average temperature has already increased 1.9 degrees Celsius, or nearly three and a half degrees Fahrenheit, since the mid-20th century.
“These ecosystems are out of equilibrium. They have to change. And one of the ways that ecosystems change is that they burn,” Wara, the Stanford researcher, said. “We can’t really prevent this. We can’t really control what is essentially a planetary-scale process of fire.”
Perhaps the worst news for the eastern United States is that wildfire smoke is most likely to hit the region during periods when the weather would otherwise be coolest. As The Washington Post has reported, eastern summers normally have a predictable rhythm: southerly winds bring hot, humid air, while northerly winds provide a respite of cooler, drier air. But this year, those northwest winds will bring clouds of eye-watering smoke.
For the past few years, western North America has been walloped by two climate-change-related disasters: extreme heat and seasonal bouts of wildfire smoke. Marshall Burke, a Stanford economist, has said that wildfire smoke has caused some of the biggest economic losses of climate change so far, at least out West.
“For California, extreme heat and extreme smoke have become the fingerprint — or even the footprint, since it feels like you’re being stepped on — of climate change,” Wara said. “I think the East has been somewhat spared from that so far, thankfully.”
But that holiday may be ending. The East Coast is facing a long, hot, smoky summer.

More than a quarter say they’re being hit hard, according to a Heatmap Pro poll.
Most Americans say that rising electricity bills are having at least “a decent amount” of impact on their household finances, according to a new Heatmap Pro poll.
The poll, which surveyed more than 3,700 registered voters last month, gives context to how electricity prices have come to dominate national headlines in recent months — and why they’ve become an urgent issue at the state and local level in a few key regions.
On the 2024 campaign trail, President Donald Trump promised to cut voters’ power bills in half within a year of getting elected. So far, that hasn’t happened: Electricity prices have risen more than twice as fast as inflation over the past 12 months and are still rising, according to government data.
Voters are beginning to feel the squeeze from that inflation. In our poll, 26% of American registered voters said that rising electricity prices were having “a lot” of impact on their personal finances. Another 31% said that rising prices were having a “decent amount” of impact.
Still, for about 40% of the country, those high prices are more a pinch than a pain. Thirty percent of registered voters said that rising prices only had “a little bit” of impact on their personal finances, while 9% said they were having “none at all.” There wasn’t a significant partisan division in sensitivity to the high prices.
The survey did show some regional distinctions, however. In the Northeast, 63% of registered voters reported that rising power prices were causing them “a lot” or “a decent amount” of trouble. In the Midwest, only 52% of voters told the poll the same thing. The South, with 56%, and the West, with 61%, landed somewhere in between.
As might be expected, lower-income voters described more trouble. More than 70% of voters with household income below $50,000 a year said that rising power bills were having “a lot” of impact on their finances. Some 62% of voters earning less than $100,000 also described issues. So did 59% of white voters without a college degree.
The rising cost of power has become a major question in New Jersey’s political race, where it has haunted ads and led Representative Mikie Sherrill, the Democratic candidate, to promise to freeze power rates for a year if she is elected.
Energy Secretary Chris Wright has said that rising electricity costs are his No. 1 concern as energy secretary, although he has conceded the Trump administration is “going to get blamed” for surging power rates. The Trump administration has revoked permits for new offshore projects along the East Coast, and congressional Republicans have ended tax credits for solar and wind energy.
Wright told Politico in August that he blames “momentum of the Obama-Biden policies” for the surging power rates. Donald Trump was president from 2017 to 2021, after Obama and before Biden.

Current conditions: Tropical Storm Imelda is gaining wind intensity this week, bringing flooding rain and storm surge to the southeastern U.S. • Hurricane Humberto, now a Category 4 storm, is passing west of Bermuda, bringing marine hazards to the U.S. East Coast • Typhoon Bualoi is pummeling the Philippines and Vietnam, where it’s already killed a dozen people.
If you were planning to cash in on the $7,500 federal tax credit for buying an electric vehicle, you’d better make moves. Today’s the last day to claim the so-called 30D tax credit. Congress moved the expiration date for the writeoff to September 30 as part of the One Big Beautiful Bill Act.
That doesn’t mean all government incentives for EVs are going away. New York still offers a $2,000 “Drive Clean Rebate” for some vehicles, and California offers up to $7,000 in rebates. Prices for new electric cars are still higher than those for comparable internal combustion vehicles, a frustratingly persistent condition the federal tax credit was meant to help address. Owning an EV has its own rewards, however, including lower fuel and maintenance costs over time. For more on how to go about choosing an EV, here’s Andrew Moseman’s guide from our Decarbonize Your Life series.

The Trump administration is opening more than 13 million acres of federal land to leasing for new coal mines. And it’s providing funding to keep demand for coal roaring. The Department of Energy announced Monday it will offer $625 million to upgrade, reopen, and “modernize” coal-fired power plants across the country.
It’s a sign of the trend Heatmap’s Matthew Zeitlin clocked in July: “Global coal demand is rising,” he wrote, “and America wants in.” Indeed, in a press release, Secretary of Energy Chris Wright boasted that the new funding would “keep our nation’s coal plants operating” and would ultimately help lower rising electricity prices. “Beautiful, clean coal will be essential to powering America’s reindustrialization and winning the AI race,” Wright said. “Coal built the greatest industrial engine the world has ever known, and with President Trump’s leadership, it will help do so again.”
The Trump administration is shutting down or shrinking roughly one third of the federal offices that track bird populations after hurricanes, map megafire risks in the Midwest, figure out new ways to fight invasive plants, and prepare communities’ stormwater drains against intense flooding. The U.S. Geological Survey’s Climate Adaptation Science Centers “are expected to drastically wind down and possibly close after Tuesday because of a lack of funds,” The Washington Post reported Monday. The centers in the South Central, Northeast, and Pacific Islands regions, which “collectively cover about one-third of the U.S. population and are funded under the Interior Department,” are potentially facing permanent closure.
The shuttering isn’t linked to a potential government shutdown, and appears planned as part of the Trump administration’s broader cuts to federal research. “We’re not willing to just drop everything and walk away,” Bethany Bradley, the co-director of the Northeast Climate Adaptation Science Center and a University of Massachusetts professor, told the newspaper. “But the reality is we can’t do this for free.”
Amazon, Google, Microsoft, utility giant Constellation, and power company Talen came together to propose a way to meet electricity needs in the nation’s largest power grid. Under their plan, the PJM Interconnection would allow large power users to volunteer for time-limited periods of reducing electricity demand when the grid is stressed. The proposal also outlines plans for time-limited use of backup generation. If making the load more flexible doesn’t work, PJM would increase the supply of firm power through procurement.
The pitch comes in response to an earlier mandatory curtailment proposal from PJM, which drew fierce blowback from many of the companies that wrote up this alternative. (“Everyone hates it,” Matthew wrote.) As analyst Aniruddh Mohan noted, PJM ultimately withdrew its initial load flexibility proposal.
Pacific Gas & Electric announced plans to spend $73 billion on upgrades to the electrical grid in California to meet the surge in demand from data centers. PG&E, as it’s known, has been deemed responsible for multiple large-scale wildfires in recent years, incurring billions in damages. As the utility told investors on a call Monday, the new investment plan “comes on the heels” of new liability reforms in the state. Under Senate Bill 254, the state expanded its wildfire fund by $18 billion and “acknowledged that the utilities and their customers cannot continue to carry the full burden of climate-driven catastrophic wildfires, especially when the utility has acted prudently,” PG&E CEO Patricia Poppe said, according to Power magazine. The utility had filed a proposal in March to build 700 miles of underground power lines between 2026 and 2028 and complete 500 miles of additional wildfire safety system upgrades by next year.
Fervo Energy, the company using fracking technology to harness the planet’s molten energy, is undeniably leading the race to commercialize next-generation geothermal. But a clear second-place contender emerged Tuesday when XGS Energy released the results from its first commercial test, the company told Heatmap exclusively. The startup’s system outperformed the executives’ expectations, setting the stage for full-scale development. While Fervo’s technology represents what’s known as “enhanced” geothermal system, XGS’ approach is what’s known as “advanced” geothermal systems that rely on closed-loop infrastructure, as Matthew previously explained.
The company is vying to challenge Fervo for leadership in the next-generation geothermal market.
The geothermal startup XGS Energy has now completed four months of tests to see whether its technology can maintain steady production of heat at temperatures above what’s needed to generate energy. Over 3,000 hours, the company monitored the drilling process and checked how heat flowed from its wells, the status of their temperature, and how precisely XGS’ mathematical predictions matched the outcome of the testing.
The results, which the company shared exclusively with Heatmap, were “almost too good,” XGS CEO Josh Prueher told me.
“Had we been within 10% of predictive performance, we would have been pretty happy with the outcome,” Prueher said. “Turns out we were within 2% under a variety of different parameters.”
“It worked like a charm,” he said.
To understand what makes XGS Energy stand out among the geothermal startups racing to commercialize next-generation technology, it helps to compare the company to its fellow Houston-based rival that’s currently leading the sector, Fervo Energy. Unlike Fervo, XGS doesn’t use fracking technology to drill horizontal wells in pursuit of hot, dry rocks from which to harvest energy.
Instead, XGS drills vertical wells and inserts a closed steel pipe with water and fills the gap between the metal and the rock with a patented slurry that conducts heat. Technology like Fervo’s requires pumping cold water over the fractured hot rocks to harvest heat. But with its method, XGS claims, it avoids losing any water.
The testing took place off the US-395 highway in a volcanic field in California’s Mojave desert, sandwiched between the eastern edge of the Sequoia National Park and western border of Death Valley National Park. The geothermal field XGS tapped is already actively producing energy for the Coso Operating Company, which runs a 270-megawatt geothermal power plant on the land. The results, the company said, showed the “unprecedented predictability and active control of field performance” of XGS’ technology “versus other geothermal systems, which are subject to complex and continuously changing subsurface reservoir conditions.”
At least one outside observer agreed. “This is impressive, and something to be proud of,” Advait Arun, an energy analyst and senior associate at the think tank Center for Energy Enterprise who co-authored a recent report on next-generation geothermal, told me.
While the 3,000 hours of testing still falls short of the year’s worth of data Fervo has produced at one of its sites, it’s the longest any other competitor in the space has successfully demonstrated its approach so far, Arun said.
“These guys would be second to Fervo in terms of their ability to prove a commercial-scale performance test,” he added.
XGS is now poised to build a 150-megawatt power plant for Meta’s New Mexico data centers. Even after that’s complete, however, Prueher said the surrounding area has nearly 3 gigawatts of untapped heat. In California, where the company is headquartered and carried out its demonstration project, there’s a growing need for clean power sources that don’t further tax the depleted water table.
“A lot of the historical sensitivities around developing in California — a state where, like many others, water usage for industrial development is kind of a no-no — because we don’t need water, we have some real advantages,” Prueher said.
At a moment when surging demand from data centers is supercharging dealmaking in the electricity sector, Prueher said XGS is looking beyond the boom from the artificial intelligence buildout.
“It’s not about data centers,” he said. “It really is just the fundamental power needs of California. With the restrictions around water usage, we line up really, really well for California.”
For now, the company remains focused on the U.S. But Prueher said XGS is well suited to export its technology to East Asia, as well, where countries along the Pacific Rim have vast geothermal potential and growing electricity demand but limited development. XGS already has ties to the Philippines and “may actually be subsurface” — i.e. digging wells — there by the end of 2026, Prueher told me.
The “big enchilada,” he said, would be establishing a foothold in Japan, where the onsen hotspring industry has long protested geothermal development they say could diminish the resource that makes the ancient bathhouse tradition possible. Prueher told me his technology mitigates concerns over fracking-induced earthquakes, as well.
For now, he said, his main market is in the fast-growing Southwest. The executive compared this moment to 2021, when he worked at a battery company. That February, Winter Storm Uri collapsed the Texas grid as natural gas pipes froze and demand for electricity to heat homes designed to stay cool in a typically arid climate skyrocketed. Back then, he said, batteries were “still a pretty new asset class.”
“People were still uncertain about how it would perform,” Prueher said. But his company was “able to keep our batteries up and operating 100% of the time, no one minute of downtime during that entire episode.”
“From a market perspective, the storm showed that, if you can bring this new type of technology into the market, it can really deliver remarkable value,” he added. “We made 10 years of revenue in six days.”
In a lot of ways, he went on, “this is the same thing.”
“We’ve proven a technology is reliable,” Prueher said. “It works at commercial scale over a period of time. We would regard this as a real pivot point in the industry.”
