Unlike another prominent climate case, there’s only upside to Held v. Montana

When Lander Busse spoke to the press after closing arguments in Held v. Montana, a trailblazing youth-led climate case that wrapped on Tuesday, he sounded optimistic.
“It feels like the beginning, really,” Busse, who at 18 is one of the case’s older plaintiffs, said. “Our next step in the process is getting our decision, which we’re really optimistic about at this point. But [we’re] also hopefully starting … a trickle-down of other litigation and activism nationally that we’ve been able to spark here.”
A cynic might describe the optimism as misguided; the idea of kids suing to control their future has historically only been entertained in the world of fiction. And yet when I asked lawyers about the case, they had a very different take. Not only is it a smart case with a strong argument, they told me, but it has practically no downsides.
“I understand the skepticism,” said James May, a law professor at Delaware Law School and founder of its Global Environmental Rights Institute. “If even a year ago, you had called and asked what I thought the prospects were of a climate case going on trial like this, I would have said next to zero. But there’s no other case like it. Never has climate been put on trial like this.”
According to the Sabin Center for Climate Change Law at Columbia University, thousands of climate change-related cases have been filed in the United States. But, May told me, other than cases over administrative issues such as permitting, none of those cases made it to trial. The fact that the youth plaintiffs actually got their day in court is by itself a big deal.
Going to trial means the plaintiffs will be able to establish, in the public record, evidence about the causes and effects of climate change.
“There are two audiences,” said Rebecca Bratspies, a law professor at the City University of New York and the founding director of the Center for Urban Environmental Reform. “There’s one audience in the court, and getting a favorable ruling in court is important. But there’s also the wider context in terms of the social conversations about how to respond to the climate crisis. A decision for the plaintiffs in a very red state like Montana would be an extremely important message to the country as a whole.”
That message, it seems, is that the courts have a newfound appetite for climate cases in a way that didn’t exist before. Three weeks ago, a judge ruled that a different youth-led climate case, Juliana v. United States, could move forward after the case was amended in response to a dismissal in 2020. Both Held and Juliana are being represented by attorneys from Our Children’s Trust, an environmental group that filed similar youth-led lawsuits in every state. But the cases rest on very different legal theories.
The plaintiffs in Held v. Montana benefit from a very specific set of circumstances. In 1972, Montana held a constitutional convention that, among other things, guaranteed in the new constitution that “the state and each person shall maintain and improve a clean and healthful environment in Montana for present and future generations.”
That gives the plaintiffs strong constitutional ground to stand on, Bratspies told me.
Montana’s state government has leaned particularly hard into climate denialism: in 2011 the legislature amended the Montana Environmental Policy Act so that climate change couldn’t be factored into environmental reviews, and this May, in an attempt to render the Held lawsuit moot, it specifically added a provision to ban any consideration of greenhouse gas emissions in environmental reviews of energy projects. If Judge Kathy Seeley, who heard the arguments in Held v. Montana, rules in favor of the plaintiffs, she could say those changes were unconstitutional and that the state of Montana would have to start considering the impacts of climate change in permitting decisions.
Juliana rests on a different legal theory entirely. In that case, the plaintiffs are alleging the federal government is violating what’s known as the public trust doctrine — an idea that goes back as far as the Romans, which holds that when a state controls land, they act as a trustee and control it for the benefit of the people.
The public trust doctrine underlies the idea that the federal government manages both national waters and federal lands for the good of the people; according to Bratspies, Juliana would argue that the same idea extends to the atmosphere, and that therefore the government is neglecting its duties by not ensuring the atmosphere remains free of greenhouse gasses and therefore affected by climate change.
When litigating cases like these, there’s a constant weighing of the risks versus the rewards, and that calculus changes according to the makeup of the courts. Juliana, if it makes its way to the United States Supreme Court, would find itself in front of a conservative-majority court that as recently as last year struck a blow at the EPA’s ability to regulate climate change.
“There’s always a risk that the Supreme Court is going to do something that is sort of unprecedented and not consistent with the long-standing body of law,” Bratspies told me. “The worst-case scenario is that the plaintiffs lose in a fashion that limits legal theories moving forward, [like if] the court narrows the public trust doctrine in a fashion that says it doesn't apply to the atmosphere because the Romans didn't think about the atmosphere.”
That could have a chilling effect on other climate cases in federal courts; any federal climate lawsuits would have to find a different legal theory to rest their cases on, and a court that is willing to upend the public trust doctrine is unlikely to be sympathetic to arguments that don’t have a constitutional right to stand on. Held v Montana, being a case in state court, has no such drawbacks. The legal ramifications of a loss would be limited only to Montana, while the social impacts of the case will remain regardless of the outcome.
“Reasonable people can disagree with me, but I see nothing but positives come out of this case,” May told me. “If the plaintiffs win, it’s a first-time ruling that underscores that the courts play a role in climate rights. But even if they lose, there’s all this evidence in the record now. That could maybe inform or inspire cases elsewhere. Even in losing it would advance the conversation more than anything else that has happened.”
It could take weeks or even months for Judge Seeley to issue a ruling, and either outcome is likely to be appealed to the Montana Supreme Court, where the plaintiffs may face an even tougher fight.
“It’s sort of a Sisyphean battle,” May said. “Every time they roll the boulder up to the top of the mountain, it rolls back down to the bottom, and they have to just keep trying. But what else is there to do? They can’t vote. They don’t hold the levers of power. They’re inheriting a melting planet. There’s nothing left to do except this.”

The number of data centers canceled after pushback set a record in the first quarter of the year, new data from Heatmap Pro shows.
Data centers are getting larger and larger. But even so, few are as large as the Sentinel Grove Technology Park, a proposed data center near Port St. Lucie, Florida.
The proposed facility — which became known as Project Jarvis — was set to be built on old agricultural land. It would use up to 1 gigawatt of electricity, enough to power a mid-size city, and bring in up to $13.5 billion in investment to the county.
The project was immediately controversial. But its developers anticipated issues: They would build their own self-contained, self-provided water facilities to service the project, and they agreed to set its 60-foot buildings back far enough from the road so that they couldn’t be seen by drivers.
It wasn’t enough. The project lost a key vote in the planning board in October. And in February, Project Jarvis’s developers withdrew their land use application entirely after Governor Ron DeSantis proposed AI regulation in the statehouse.
The facility was the largest data center project canceled after facing opposition in the first quarter of 2026. But it wasn’t the only one.
At least 20 proposed data center projects were canceled after local pushback during the first three months of 2026, smashing a record set only in the previous quarter, according to a review of press accounts, public records, and project announcements conducted by Heatmap Pro.
These canceled projects accounted for more than $41.7 billion in investment and represented at least 3.5 gigawatts of electricity demand.
The cancellations reveal the rapidly expanding backlash to data center construction has not yet peaked. From Georgia to Pennsylvania, locals have rebelled against newly proposed data centers, even when the planned facilities are not planning to run artificial intelligence models.

If anything, fights over data centers are surging now. Heatmap Pro’s researchers added roughly 100 new data center fights to their database during the first three months of the past year, a new record.
These fights are succeeding in terminating projects. Last year, roughly 25 data center projects were canceled nationwide after facing some type of local opposition, according to Heatmap Pro data. The country is likely to break that record in 2026 over the next few weeks, our data suggests — only five months into the year.
At least $85 billion in data center projects have been canceled over the past three years, according to Heatmap Pro data.

These numbers haven’t been previously reported. Over the past year, researchers at our intelligence platform Heatmap Pro have conducted a comprehensive national survey of local opposition to data center construction. They have regularly called every U.S. county to tally data center cancellations and any new rules limiting data center construction.
This data is normally available to companies and individuals who subscribe to Heatmap Pro, but we periodically publish a high-level summary of this data. We last released our results in January.
Current conditions: The East Coast’s Acela corridor is cooling down this week, with temperatures dropping from 85 degrees Fahrenheit in Philadelphia yesterday to the 60s for the rest of the week • Cape Agulhas is under one of South Africa’s Orange Level 6 warnings for damaging winds and dangerous waves • Floods and landslides in Brazil’s northern state of Pernambuco have left six dead and thousands displaced.
The Securities and Exchange Commission has advanced a measure to formally end Biden-era climate disclosure rules for publicly-traded companies. The regulator sent the proposal to the White House’s Office of Management and Budget for review on May 4, according to a post on a government website first spotted by Bloomberg. The Wall Street watchdog’s 2024 disclosure rule mandated that publicly traded companies report on the material risks climate change poses to their business models, including the financial impact of extreme weather. Some large companies would have been required to disclose Scope 1 emissions, which are produced by the firm’s own operations, and Scope 2 emissions, which are produced by companies with which the firm does off-site business such as electricity. The rule had already been watered down before its finalization to remove Scope 3 emissions, which come from suppliers up and down the value chain and from customers who use a product such as oil.
In an even bigger move, the SEC also proposed scrapping mandatory quarterly reporting for U.S.-listed companies, instead switching to a twice-yearly filing. The idea, which President Donald Trump first floated years ago as a way of getting companies to focus on longer-term goals, “would provide companies with increased regulatory flexibility,” SEC chair Paul Atkins told the Financial Times. “Public companies have an obligation under the federal securities laws to provide information that is material to investors. Yet, the rigidity of the SEC’s rules has prevented companies and their investors from determining for themselves the interim reporting frequency that best serves their business needs and investors.” While cast as part of a larger deregulatory push, the move could actually be a boon to climate action. Supporters of decarbonization have long lamented how quarterly reporting norms disincentivized costly bets that take longer than three months to pan out.
If you have ever body surfed in the ocean — or observed how docks and peers weather over time — it’s easy to intuit why harnessing renewable energy from waves is so tricky. Among experts who often list wave energy along with tidal power as two sources of underdeveloped but potentially promising renewable energy, the latter has long been considered the more commercially viable, with turbines harnessing tidal flows already in operation in France and elsewhere. Wave energy, by contrast, has been perceived as a riskier frontier in the energy industry.
That didn’t stop wave-energy startup Panthalassa from raising $140 million in a Series B round led by Silicon Valley billionaire Peter Thiel this week as the company looks to develop floating data centers that can operate in open ocean. The financing will fund the completion of the company’s pilot manufacturing facility near Portland, Oregon, and speed up deployment of its Ocean-3 series of facilities that “will perform AI inference computing at sea” with power generated from ocean waves.
“There are three sources of energy on the planet with tens of terawatts of new capacity potential: solar, nuclear, and the open ocean,” Panthalassa CEO and co-founder Garth Sheldon-Coulson said in a statement. “We’ve built a technology platform that operates in the planet’s most energy-dense wave regions, far from shore, and turns that resource into reliable clean power. We’re now ready to build factories, deploy fleets, and provide a sustainable new source of energy for humanity.” The deal, per the Financial Times, values the company at about $1 billion. “The future demands more compute than we can imagine,” Thiel said in a press release. “Extra-terrestrial solutions are no longer science fiction. Panthalassa has opened the ocean frontier.”
The company has some competition. Earlier this year, the San Francisco-based Aikido Technologies launched a new line of floating platforms for deep-water offshore wind turbines that include data centers built into the ballasts.
Allow me to give you a glimpse into the anxious mind of a young father: Sometimes, I distract myself from my fear over what global weather patterns might look like by the time my one-year-old daughter is my age with my more urgent terror over what particulate matter is entering her perfect little lungs and what microplastics sneak into even her home-cooked meals. Well, worry not! Turns out the two aren’t mutually exclusive. In theory, I knew this was always the case, since the rise of plastic pollution is at least somewhat spurred on by oil and gas companies making big money off the feedstocks for the cheap, single-use plastics that break down into dangerous tiny particles in our environment. But new research shows that microplastics in the atmosphere are actually magnifying the effects of climate change. In a new paper published in the journal Nature Climate Change, scientists in China and the U.S. outlined how tiny, colored plastic bits absorb sunlight as the wind blows them around the world, trapping heat and adding to temperature rise. “The plastic problem is not just in our blue oceans, it is also in the invisible skies above us,” Hongbo Fu, a co-author of the study and an atmospheric scientist at Fudan University in Shanghai, said at a press conference, per Bloomberg. “Climate models need to be updated.”

Like wave and tidal power, geothermal was once a sleepy corner of the clean energy world. But next-generation startups that promised to use new drilling techniques to harness geothermal energy in more places than ever thought possible are radically upending an industry that saw its largest power station — the Geysers in California — built in the 1960s and hitherto hadn’t aimed higher. Until a few years ago, next-generation geothermal drilling was esoteric even among energy nerds. But things change quickly in the modern energy business. Fervo Energy, the first major next-generation startup to prove that fracking technology could be used to revolutionize geothermal power, is now eyeing a $6.5 billion valuation. That’s according to a document the company filed with the SEC this week as it prepares to raise more than $1.3 billion in an initial public offering of its stock.
Fervo sees a big market. As Heatmap’s Matthew Zeitlin wrote last month when the company first filed to go public, Fervo told investors its reviewed leases represent over 40 gigawatts of energy. That’s equal to about 15% of all installed solar capacity in the U.S.

The United Arab Emirates already ranks as the world’s seventh-largest producer of crude, and could ascend as the country’s exit from the Organization of the Petroleum Exporting Countries frees Abu Dhabi to pump for oil. The UAE’s debut atomic power plant — the four-reactor, Korean-built Barakah station in Abu Dhabi — set a new standard for nuclear construction in a Western-aligned nation and vaulted the federation of monarchies to the forefront of global discussions about fission. Now the UAE is making a big move on solar. Abu Dhabi’s state-owned renewables developer Masdar has signed a deal with Emirates Water and Electricity Company to deploy more than 30 gigawatts of solar capacity and 8 gigawatts of batteries. “As the driving force behind the UAE’s energy transition, EWEC is at the forefront of a global shift towards sustainable, utility-scale power and water production,” Ahmed Ali Alshamsi, the utility chief in charge of the Emirates Water and Electricity Company, told PV Tech. “This CFA with Masdar is a pivotal strategic tool that empowers us to accelerate this transformation and meet 60% of Abu Dhabi’s total energy demand from renewable and clean sources by 2035.”
Norway led the world in electric vehicle adoption. It’s now at the forefront of autonomous vehicle adoption. Europe’s first self-driving bus without a supervisor onboard is set to be rolled out in the southwestern city of Stavanger following a recent regulatory change. While the bus still requires preparation by a human before operating, the project has been underway since 2022 and represents Europe’s most advanced public deployment of the technology.
Rob talks with the billionaire investor and philanthropist about how energy, Chinese EVs, and why he’s “very optimistic” that Congress will pass permitting reform this year.
If you work around climate or clean energy, you probably know about John Arnold. Although he began his career as a natural gas trader, Arnold has since become one of the country’s most important clean energy investors. He’s the chairman of Grid United, a transmission development firm undertaking some of the country’s most ambitious power line projects, and he is an investor in the advanced geothermal startup Fervo. He and his wife Laura run the philanthropic organization Arnold Ventures.
On this week’s episode of Shift Key, Rob talks with Arnold about the current energy chaos and what might come next. They discuss Arnold’s first trip to China, whether Congress might pass permitting reform this year, and what clean energy companies should learn from the fossil fuel industry.

Here is an excerpt from our conversation:
Robinson Meyer: What needs to change or what needs to happen between now and, say, the end of the year for [a permitting deal] to actually get done?
John Arnold: So I think on an election year, it's very unusual for any big piece of bipartisan legislation to get passed, really, the whole year. And so what we're really looking at is most likely is that it would get passed after the election in the lame duck period. And so you start working backwards from there and really need to have language that's agreed upon in the next 45 days. It's hard to work over the summer. Congress scatters. Everybody scatters. Then you come back. There's a little bit of work time in September, and then everybody's focused on the elections. So the bill needs to get written today. And then again, in the next 45 days, and there's a lot of work happening behind the scenes. So again, sometimes it's hard to know exactly where it is, but everybody's saying the right things. There's been fits and stops to date, particularly when the administration hit the pause on offshore wind. They've made some changes. They brought Senator Whitehouse back to the negotiating table, for instance. So again, everything I think is looking good, but getting anything passed in D.C. these days might be a long shot.
