On EPA’s CO2 math, the British atom, and Ram’s reversal

Current conditions: A prolonged heatwave in Mississippi is breaking nearly century-old temperature records and driving the thermometer up to 100 degrees Fahrenheit again this week • A surge of tropical moisture is steaming the West Coast, with temperatures up to 10 degrees higher than average • Heavy rainfall has set off landslide warnings in every major country in West Africa.
The Trump administration asked a federal judge on Friday to withdraw the Department of the Interior’s approval of a wind farm off the coast of Maryland, Reuters reported. Known as the Maryland Offshore Wind Project, the $6 billion array of as many as 114 turbines in a stretch of federal ocean was set to begin construction next year. Developer US Wind — a joint venture between the investment firm Apollo Global Management and a subsidiary of the Italian industrial giant Toto Holding SpA — had already faced pushback from Republicans. The town of Ocean City sued to overturn the project’s permits at the federal and state levels. When the Interior Department first announced it was reconsidering the permits in August, Mary Beth Carozza, the Republican state senator representing the area, welcomed the move but warned in a statement the news site Maryland Matters cited that opponents’ campaign against the project, known as Stop Offshore Wind, “won’t stop fighting until the Maryland offshore wind project is completely dead.”
It’s all part of President Donald Trump’s widening “war against wind” energy that kicked off the moment he returned to the White House and issued an order halting approvals for new offshore and onshore turbines. If you read the timeline Heatmap’s Emily Pontecorvo neatly charted out earlier this month, you’ll notice how quickly the administration’s multi-agency crackdown on wind power expanded, particularly after the passage of the One Big Beautiful Bill Act on July 4. The industry is just starting to push back. As I reported in this newsletter two weeks ago, the owners of the Rhode Island offshore project Revolution Wind that Trump halted unilaterally filed a lawsuit claiming the administration illegally withdrew its already-finalized permits. US Wind said it intends “to vigorously defend those permits in federal court, and we are confident that the court will uphold their validity and prevent any adverse action against them.”

The Environmental Protection Agency on Friday proposed killing the long-standing program requiring thousands of facilities across the country to report the amount of heat-trapping greenhouse gas they release into the atmosphere every year. Since 2010, the government has collected the data on emissions from coal-fired plants, oil refineries, steel mills, and other industrial sites, which now represents what The New York Times called “the country’s most comprehensive way to track greenhouse gases.”
The decision could have grave consequences for carbon capture and storage. Some had hoped Trump’s vision of unleashing fossil fuels might spur more investment in the technology to capture emissions before they enter the atmosphere and recycle the gas for industrial use or store it in wells underground. But the mix of hardware, pipelines, and storage sites remains so underdeveloped that the EPA in June said it’s “extremely unlikely that the infrastructure necessary for CCS can be deployed” by the 2032 deadline a previous Biden-era rule had set for equipping fossil fuel plants with carbon capture technology, E&E News reported at the time. Eliminating the Greenhouse Gas Reporting Program hampers all the federal programs that rely on its data. That includes the carbon capture subsidy, known by its tax code section head 45Q, which Republicans recently dialed up in Trump’s reconciliation law. The rules for claiming the tax credit include filing technical details to the EPA’s emissions program. When Heatmap’s Robinson Meyer reached out to the EPA to ask whether gutting the database posed a setback for companies looking to claim the credits, an agency spokesperson pointed him to a line in Friday’s proposal: “We anticipate that the Treasury Department and the IRS may need to revise the regulation,” the legal proposal says. “The EPA expects that such amendments could allow for different options for stakeholders to potentially qualify for tax credits.”
In a flurry of deals on Sunday night, at least a half-dozen U.S. nuclear companies unveiled plans for new facilities in the United Kingdom as Washington looks to fill order books for its fuel makers and next-generation reactor companies and London looks to ramp up its atomic energy output. Among the deals:
The announcements add to what Heatmap’s Katie Brigham called the “nuclear power dealmaking boom.” In a recent paper, policy experts at the center left think tank Third Way concluded that “the U.S. and U.K. are well-suited for further collaboration on nuclear, specifically SMR and Gen IV technologies,” and “could reduce deployment costs through learning rates and commissioning larger order books.”
Nearly a decade of bureaucratic tinkering at the Federal Energy Regulatory Commission came to an end so abruptly it’s most succinctly captured in onomatopoeia: “Womp,” Harvard Law School’s electricity law program director Ari Peskoe wrote on X. “With one paragraph, FERC ends a 7.5-year effort to update its approach to reviewing proposed interstate gas pipelines.” The measure would have implemented a new formula for assessing the value of new interstate gas lines that would have weighted the environment more heavily than the existing methodology, which was written in 1999. But the push to modernize the criteria after three decades “was never a serious effort,” former FERC Chairman Neil Chatterjee posted on X. “We got bullied into starting it and put on a show for years to hold protesters at bay. Just being honest. R and D led @ferc majorities both faked it.”
Ram has canceled its electric pickup truck, long expected to be a competitor to the battery-powered versions of the Ford F-150 and Chevrolet Silverado, InsideEVs reported. Parent company Stellantis said it would discontinue the 2026 battery-powered Ram 1500 REV “as demand for full-size battery-electric trucks slows in North America.” Rivals such as GM have seen a boom in EV sales in recent months, that is likely driven by the law Trump signed that rapidly phased out federal tax credits after this month. As Heatmap’s Matthew Zeitlin wrote recently, August turned out to be the best month for EV sales “in U.S. history, with just over 146,000 units sold, comprising almost 10% of total car sales that month.” Ford is still investing in what is billed as a Model T moment for EV construction. And, as I have reported here in this newsletter, Tesla’s plunge in popularity — even with former customers — has opened up more of the EV market to other vendors.
Though Ram’s all-electric pickup truck turned out to be a non-starter, its extended-range battery electric truck, formerly known as the Ramcharger, will now take on the 1500 REV moniker with a 2026 launch date. As Heatmap contributor and Shift Key podcast cohost Jesse Jenkins wrote when the Ramcharger was announced, “The economics and capabilities of a range-extended EV thus make a lot of sense, especially for massive vehicles like the full-size trucks and SUVs so many Americans love. And they squash any concerns about range anxiety that might give buyers pause.”
Scientists have long sought an economical way to harness renewable power from waves. But as Julian Spector wrote in Canary Media: “The first rule of wave power startups is that they always fail. But a plucky company called Eco Wave Power is doing its best to prove that rule wrong, and it just notched an important win in Los Angeles.” The company this month installed a 100-kilowatt system on a concrete wharf in the port of Los Angeles, with seven steel floaters affixed to a central structure that bobs in the waves, “building up hydraulic pressure that gets converted to electric power by machinery in shipping containers on shore.” If the pilot pans out and Eco Wave gets a chance to bid on a larger area of the port, the technology could — at least in theory — generate power 90% of the time, supplying electrons at a capacity factor higher than almost any other energy source besides nuclear.

Europeans have been “snow farming” for ages. Now the U.S. is finally starting to catch on.
February 2015 was the snowiest month in Boston’s history. Over 28 days, the city received a debilitating 64.8 inches of snow; plows ran around the clock, eventually covering a distance equivalent to “almost 12 trips around the Equator.” Much of that plowed snow ended up in the city’s Seaport District, piled into a massive 75-foot-tall mountain that didn’t melt until July.
The Seaport District slush pile was one of 11 such “snow farms” established around Boston that winter, a cutesy term for a place that is essentially a dumpsite for snow plows. But though Bostonians reviled the pile — “Our nightmare is finally over!” the Massachusetts governor tweeted once it melted, an event that occasioned multiple headlines — the science behind snow farming might be the key to the continuation of the Winter Olympics in a warming world.
The number of cities capable of hosting the Winter Games is shrinking due to climate change. Of 93 currently viable host locations, only 52 will still have reliable winter conditions by the 2050s, researchers found back in 2024. In fact, over the 70 years since Cortina d’Ampezzo first hosted the Olympic Games in 1956, February temperatures in the Dolomites have warmed by 6.4 degrees Fahrenheit, according to Climate Central, a nonprofit climate research and communications group. Italian organizers are expected to produce more than 3 million cubic yards of artificial snow this year to make up for Mother Nature’s shortfall.
But just a few miles down the road from Bormio — the Olympic venue for the men’s Alpine skiing events as well as the debut of ski mountaineering next week — is the satellite venue of Santa Caterina di Valfurva, which hasn’t struggled nearly as much this year when it comes to usable snow. That’s because it is one of several European ski areas that have begun using snow farming to their advantage.
Like Ruka in Finland and Saas-Fee in Switzerland, Santa Caterina plows its snow each spring into what is essentially a more intentional version of the Great Boston Snow Pile. Using patented tarps and siding created by a Finnish company called Snow Secure, the facilities cover the snow … and then wait. As spring turns to summer, the pile shrinks, not because it’s melting but because it’s becoming denser, reducing the air between the individual snowflakes. In combination with the pile’s reduced surface area, this makes the snow cold and insulated enough that not even a sunny day will cause significant melt-off. (Neil DeGrasse Tyson once likened the phenomenon to trying to cook an entire potato with a lighter; successfully raising the inner temperature of a dense snowball, much less a gigantic snow pile, requires more heat.)
Shockingly little snow melts during storage. Snow Secure reports a melt rate of 8% to 20% on piles that can be 50,000 cubic meters in size, or the equivalent of about 20 Olympic swimming pools. When autumn eventually returns, ski areas can uncover their piles of farmed snow and spread it across a desired slope or trail using snowcats, specialized groomers that break up and evenly distribute the surface. For Santa Caterina, the goal was to store enough to make a nearly 2-mile-long cross-country trail — no need to wait for the first significant snowfall of the season, which creeps later and later every year.
“In many places, November used to be more like a winter month,” Antti Lauslahti, the CEO of Snow Secure, told me. “Now it’s more like a late-autumn month; it’s quite warm and unpredictable. Having that extra few weeks is significant. When you cannot open by Thanksgiving or Christmas, you can lose 20% to 30% of the annual turnover.”
Though the concept of snow farming is not new — Lauslahti told me the idea stems from the Finnish tradition of storing snow over the summer beneath wood chips, once a cheap byproduct of the local logging industry — the company's polystyrene mat technology, which helps to reduce summer melt, is. Now that the technique is patented, Snow Secure has begun expanding into North America with a small team. The venture could prove lucrative: Researchers expect that by the end of the century, as many as 80% of the downhill ski areas in the U.S. will be forced to wait until after Christmas to open, potentially resulting in economic losses of up to $2 billion.
While there have been a few early adopters of snow farming in Wisconsin, Utah, and Idaho, the number of ski areas in the United States using the technique remains surprisingly low, especially given its many other upsides. In the States, the most common snow management system is the creation of artificial snow, which is typically water- and energy-intensive. Snow farming not only avoids those costs — which can also have large environmental tolls, particularly in the water-strapped West — but the super-dense snow farming produces is “really ideal” for something like the Race Centre at Canada’s Sun Peaks Resort, where top athletes train. Downhill racers “want that packed, harder, faster snow,” Christina Antoniak, the area’s director of brand and communications, told me of the success of the inaugural season of snow farming at Sun Peaks. “That’s exactly what stored snow produced for that facility.”
The returns are greatest for small ski areas, which are also the most vulnerable to climate change. While the technology is an investment — Antoniak ballparked that Sun Peaks spent around $185,000 on Snow Secure’s siding — the money goes further at a smaller park. At somewhere like Park City Mountain in Utah, stored snow would cover only a small portion of the area’s 140 miles of skiable routes. But it can make a major difference for an area down the road like the Soldier Hollow Nordic Center, which has a more modest 20 miles of cross-country trails.
In fact, the 2025-2026 winter season will be the Nordic Center’s first using Snow Secure’s technology. Luke Bodensteiner, the area’s general manager and chief of sport, told me that alpine ski areas are “all very curious to see how our project goes. There is a lot of attention on what we do, and if it works out satisfactorily, we might see them move into it.”
Ensuring a reliable start to the ski season is no small thing for a local economy; jobs and travel plans rely on an area being open when it says it will be. But for the Soldier Hollow Nordic Center, the stakes are even higher: The area is one of the planned host venues of the 2034 Salt Lake City Winter Games. “Based on historical weather patterns, our goal is to be able to make all the snow that we need for the entire Olympic trail system in two weeks,” Bodensteiner said, adding, “We envision having four or five of these snow piles around the venue in the summer before the Olympic Games, just to guarantee — in a worst case scenario — that we’ve got snow on the venue.”
Antoniak, at Canada’s Sun Peaks, also told me that their area has been a bit of a “guinea pig” when it comes to snow farming. “A lot of ski areas have had their eyes on Sun Peaks and how [snow farming is] working here,” she told me. “And we’re happy to have those conversations with them, because this is something that gives the entire industry some more resiliency.”
Of course, the physics behind snow farming has a downside, too. The same science saving winter sports is also why that giant, dirty pile of plowed snow outside your building isn’t going anywhere anytime soon.
Current conditions: A train of three storms is set to pummel Southern California with flooding rain and up to 9 inches mountain snow • Cyclone Gezani just killed at least four people in Mozambique after leaving close to 60 dead in Madagascar • Temperatures in the southern Indian state of Kerala are on track to eclipse 100 degrees Fahrenheit.
What a difference two years makes. In April 2024, New York announced plans to open a fifth offshore wind solicitation, this time with a faster timeline and $200 million from the state to support the establishment of a turbine supply chain. Seven months later, at least four developers, including Germany’s RWE and the Danish wind giant Orsted, submitted bids. But as the Trump administration launched a war against offshore wind, developers withdrew their bids. On Friday, Albany formally canceled the auction. In a statement, the state government said the reversal was due to “federal actions disrupting the offshore wind market and instilling significant uncertainty into offshore wind project development.” That doesn’t mean offshore wind is kaput. As I wrote last week, Orsted’s projects are back on track after its most recent court victory against the White House’s stop-work orders. Equinor's Empire Wind, as Heatmap’s Jael Holzman wrote last month, is cruising to completion. If numbers developers shared with Canary Media are to be believed, the few offshore wind turbines already spinning on the East Coast actually churned out power more than half the time during the recent cold snap, reaching capacity factors typically associated with natural gas plants. That would be a big success. But that success may need the political winds to shift before it can be translated into more projects.

President Donald Trump’s “drill, baby, drill” isn’t moving American oil extractors, whose output is set to contract this year amid a global glut keeping prices low. But production of natural gas is set to hit a record high in 2026, and continue upward next year. The Energy Information Administration’s latest short-term energy outlook expects natural gas production to surge 2% this year to 120.8 billion cubic feet per day, from 118 billion in 2025 — then surge again next year to 122.3 billion cubic feet. Roughly 69% of the increased output is set to come from Appalachia, Louisiana’s Haynesville area, and the Texas Permian regions. Still, a lot of that gas is flowing to liquified natural gas exports, which Heatmap’s Matthew Zeitlin explained could raise prices.
The U.S. nuclear industry has yet to prove that microreactors can pencil out without the economies of scale that a big traditional reactor achieves. But two of the leading contenders in the race to commercialize the technology just crossed major milestones. On Friday, Amazon-backed X-energy received a license from the Nuclear Regulatory Commission to begin commercial production of reactor fuel high-assay low-enriched uranium, the rare but potent material that’s enriched up to four times higher than traditional reactor fuel. Due to its higher enrichment levels, HALEU, pronounced HAY-loo, requires facilities rated to the NRC’s Category II levels. While the U.S. has Category I facilities that handle low-enriched uranium and Category III facilities that manage the high-grade stuff made for the military, the country has not had a Category II site in operation. Once completed, the X-energy facility will be the first, in addition to being the first new commercial fuel producer licensed by the NRC in more than half a century.
On Sunday, the U.S. government airlifted a reactor for the first time. The Department of Defense transported one of Valar Atomics’ 5-megawatt microreactors via a C-17 from March Air Reserve Base in California to Hill Air Force Base in Utah. From there, the California-based startup’s reactor will go to the Utah Rafael Energy Lab in Orangeville, Utah, for testing. In a series of posts on X, Isaiah Taylor, Valar’s founder, called the event “a groundbreaking unlock for the American warfighters.” His company’s reactor, he said, “can power 5,000 homes or sustain a brigade-scale” forward operating base.

After years of attempting to sort out new allocations from the dwindling Colorado River, negotiators from states and the federal government disbanded Friday without a plan for supplying the 40 million people who depend on its waters. Upper-basin states Colorado, Utah, Wyoming, and New Mexico have so far resisted cutting water usage when lower-basin states California, Arizona, and Nevada are, as The Guardian put it, “responsible for creating the deficit” between supply and demand. But the lower-basin states said they had already agreed to substantial cuts and wanted the northern states to share in the burden. The disagreement has created an impasse for months; negotiators blew through deadlines in November and January to come up with a solution. Calling for “unprecedented cuts” that he himself described as “unbelievably harsh,” Brad Udall, senior water and climate research scientist at Colorado State University’s Colorado Water Center, said: “Mother Nature is not going to bail us out.”
In a statement Friday, Secretary of the Interior Doug Burgum described “negotiations efforts” as “productive” and said his agency would step in to provide guidelines to the states by October.
Europe’s “regulatory rigidity risks undermining the momentum of the hydrogen economy. That, at least, is the assessment of French President Emmanuel Macron, whose government has pumped tens of billions of euros into the clean-burning fuel and promoted the concept of “pink hydrogen” made with nuclear electricity as the solution that will make energy technology take off. Speaking at what Hydrogen Insight called “a high-level gathering of CEOs and European political leaders,” Macron, who is term-limited in next year’s presidential election, said European rules are “a crazy thing.” Green hydrogen, the version of the fuel made with renewable electricity, remains dogged by high prices that the chief executive of the Spanish oil company Repsol said recently will only come down once electricity rates decrease. The Dutch government, meanwhile, just announced plans to pump 8 billion euros, roughly $9.4 billion, into green hydrogen.
Kazakhstan is bringing back its tigers. The vast Central Asian nation’s tiger reintroduction program achieved record results in reforesting an area across the Ili River Delta and Southern Balkhash region, planting more than 37,000 seedlings and cuttings on an area spanning nearly 24 acres. The government planted roughly 30,000 narrow-leaf oleaster seedlings, 5,000 willow cuttings, and about 2,000 turanga trees, once called a “relic” of the Kazakh desert. Once the forests come back, the government plans to eventually reintroduce tigers, which died out in the 1950s.
In this special episode, Rob goes over the repeal of the “endangerment finding” for greenhouse gases with Harvard Law School’s Jody Freeman.
President Trump has opened a new and aggressive war on the Environmental Protection Agency’s ability to limit climate pollution. Last week, the EPA formally repealed its scientific determination that greenhouse gases endanger human health and the environment.
On this week’s episode of Shift Key, we find out what happens next.
Rob is joined by Jody Freeman, the director of the Environmental and Energy Law Program at Harvard Law School, to discuss the Trump administration’s war on the endangerment finding. They chat about how the Trump administration has already changed its argument since last summer, whether the Supreme Court will buy what it’s selling, and what it all means for the future of climate law.
They also talk about whether the Clean Air Act has ever been an effective tool to fight greenhouse gas pollution — and whether the repeal could bring any upside for states and cities.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.

Here is an excerpt from our conversation:
Jody Freeman: The scientific community, you know, filed comments on this proposal and just knocked all of the claims in the report out of the box, and made clear how much evidence not only there was in 2009, for the endangerment finding, but much more now. And they made this very clear. And the National Academies of Science report was excellent on this. So they did their job. They reflected the state of the science and EPA has dropped any frontal attack on the science underlying the endangerment finding.
Now, it’s funny. My reaction to that is like twofold. One, like, yay science, right? Go science. But two is, okay, well, now the proposal seems a little less crazy, right? Or the rule seems a little less crazy. But I still think they had to fight back on this sort of abuse of the scientific record. And now it is the statutory arguments based on the meaning of these words in the law. And they think that they can get the Supreme Court to bite on their interpretation.
And they’re throwing all of these recent decisions that the Supreme Court made into the argument to say, look what you’ve done here. Look what you’ve done there. You’ve said that agencies need explicit authority to do big things. Well, this is a really big thing. And they characterize regulating transportation sector emissions as forcing a transition to EVs. And so to characterize it as this transition unheralded, you know, and they need explicit authority, they’re trying to get the court to bite. And, you know, they might succeed, but I still think some of these arguments are a real stretch.
Robinson Meyer: One thing I would call out about this is that while they’ve taken the climate denialism out of the legal argument, they cannot actually take it out of the political argument. And even yesterday, as the president was announcing this action — which, I would add, they described strictly in deregulatory terms. In fact, they seemed eager to describe it not as an environmental action, not as something that had anything to do with air and water, not even as a place where they were. They mentioned the Green New Scam, quote-unquote, a few times. But mostly this was about, oh, this is the biggest deregulatory action in American history.
It’s all about deregulation, not about like something about the environment, you know, or something about like we’re pushing back on those radicals. It was ideological in tone. But even in this case, the president couldn’t help himself but describe climate change as, I think the term he used is a giant scam. You know, like even though they’ve taken, surgically removed the climate denialism from the legal argument, it has remained in the carapace that surrounds the actual ...
Freeman: And I understand what they say publicly is, you know, deeply ideological sounding and all about climate is a hoax and all that stuff. But I think we make a mistake … You know, we all get upset about the extent to which the administration will not admit physics is a reality, you know, and science is real and so on. But, you know, we shouldn’t get distracted into jumping up and down about that. We should worry about their legal arguments here and take them seriously.
