We’re now a quarter of the way through the 21st century, and it’s indisputable that climate is one of the most important stories of our time. That’s our philosophy here at Heatmap, but just about everything around us illustrates it, too — from government policy and tech to movies and reality TV.
And of course — or maybe, especially — books.
It’s been about 17 years since the term “cli-fi” (or “climate fiction”) was first coined, and in the meantime, books that touch on climate themes in both fiction and nonfiction have taken off like the Keeling Curve. In 2025, we’ll be reading novels that imagine life in San Francisco after years of deluge and investigative reports into subjects such as how companies have gotten away with dumping forever chemicals into the environment for so long. There will be new natural histories to dive into — on the desert, forests, prairies, and even on the chemical compound CO2 — as well as new frames of thinking about climate change and how we approach its solutions.
Because so many 2025 books will touch on climate themes, I’ve set aside a section of honorable mentions at the end of this list that are also worth checking out. The division doesn’t indicate quality; I chose the primary 18 based on my subjective excitement and to showcase different genres, publishers, and authors. It might be in the appendix that you find a book on the topic you’re personally most excited about (Arctic exploration? Solar geoengineering? Florida-set family dramas?) for next year.
Finally, if you want to see all these books in one place or judge them by their (excellent) covers, you can browse our curated list on Bookshop here.
The U.S. government’s Fifth National Climate Assessment section on the Southwest reads like an apocalyptic horror story: “Heat-related mortality,” “increased wildfire risks,” and “longer and more severe droughts” all make it into the opening few paragraphs. The truth is that the hottest and driest region of the United States is home to 60 million people, many of whom will have to adapt to a more extreme future in the coming years. In New Mexico-born journalist Kyle Paoletta’s debut book, American Oasis, he traces the allure of places like Albuquerque, Phoenix, El Paso, and Las Vegas back to the Athapaskan migration from the sub-Arctic around 1100 BCE and through the heydays of Arizona Highways, a magazine from the 1950s, while also charting what lies ahead for those who are drawn to making the desert, however impossibly, their home. Preorder it here.
Speaking of the American desert, on the fiction side of things this winter comes Madeleine Watts’ latest novel, Elegy, Southwest. Watts made a name for herself as a writer of cli-fi after the release of her 2021 novel, The Inland Sea, set against the backdrop of Australia’s fires and floods, and she returns this year with a road trip novel that follows Eloise, a doctoral student studying the Colorado River and climate change. As part of her research, Eloise flies to Las Vegas for a road trip through the Southwest with her husband, Lewis, to whom the novel is addressed. Along the way, Eloise begins to believe she’s pregnant, while Lewis struggles with the fresh grief of losing his mother. As Watts told an interviewer of her process for The Inland Sea, “I wanted to write … about what it’s like to live in the experience of a changing climate that is not always a tangible part of your day-to-day but that’s already there – it’s in the air all around you.” Expect a similar treatment this go-round. Preorder it here.
Eric Puchner’s new novel, Dream State, is the story of two marriages set over 50 years. With the book opening in 2004, that naturally requires some speculation about the future — in this case, the future of “a rapidly warming Montana.” As The Indypendent writes in an early review, “The looming climate crisis — declining snowfall, depleted wildlife, raging seasonal wildfires, and abnormally warm temperatures — is writ large in the book, forming a blistering backdrop, highlighting newfound restrictions on what both residents and short-term visitors can now see and do in the area.” The novel has earned praise from Pulitzer Prize-winner Adam Johnson, who called it “a masterpiece,” as well as author Lynn Steger Strong, who has a climate book of her own on the list below. Preorder it here.
Four years ago, Argentinean author Agustina Bazterrica burst onto Americans’ radars with the English-language translation of her 2017 novel Tender Is the Flesh, a book that imagines a future in which animals have become toxic to humans, leading us to resort to industrialized cannibalism. (Critics have described it, vividly, as “splatterpunk.”) This year, Bazterrica turns her attention from factory farming to the climate catastrophe, telling the story of a member of a “Sacred Sisterhood” cloistered in a mysterious convent who is prompted to reflect on her life outside its walls when a new acolyte arrives. Don’t expect Bazterrica to soften her critiques of capitalism here, though it’s not all doom and gloom; early readers have said The Unworthy “ends on a light note of hope.” Preorder it here.
Charlotte McConaghy’s follow-up novel to her critically acclaimed 2020 debut, Migrations, is set on a fictional research island, Shearwater, located between Australia and Antarctica. Dominic Salt, the caretaker of the island’s seed vault, has called the refuge home for the past eight years — ever since fleeing Australia’s accelerating natural disasters, hoping to find a safer place to raise his three children. But with rising sea levels now threatening the island, Dominic and his family have just seven weeks left before they plan to move on. Just before their departure, Dominic’s oldest daughter discovers a woman who has shipwrecked on shore, and the tension — and mystery — starts to grow. Wild Dark Shore has earned a starred review from Kirkus, which calls it a “terrific thriller.” Preorder it here.
Climatologist, World Weather Attribution co-founder, and 2024 Trailblazing Women in Climate laureate Friederike Otto does not mince words about who is most impacted by extreme weather — and who needs to be involved in the solutions. “If we leave the issue of climate change to white men, it’ll continue to be treated as a physical problem with technological solutions,” she has said, adding, “The more diverse the people working on it, the closer we get to implementing these solutions and making progress on climate change.” Her new book, Climate Injustice, elaborates on her thesis further, using the stories of real people in the Global South to illustrate how exploitation, sexism, and colonialism have created a crisis with unequal impacts. Preorder it here.
Everyone who works in the climate space is familiar with the question posed in the title of this book. Entomologist Douglas W. Tallamy is one of the leading proponents of the native gardens movement, and in How Can I Help?, he answers a query implied in his own earlier book, 2009’s Bringing Nature Home: that “unless we restore native plants to our suburban ecosystems, the future of biodiversity in the United States is dim.” How Can I Help? is structured to address some of the most common questions Tallamy encounters during his lectures about how individuals can become directors of their own miniature national parks at home. Despite the daunting challenge of biodiversity loss, Tallamy offers actionable ideas for helping the planet, with conservation beginning in your backyard. Preorder it here.
If I had to make one prediction for 2025, it’d be that we will hear a lot more about per- and polyfluoroalkyl substances — that is, the “forever chemicals” commonly known as PFAS. The chemicals are found in everything from our dental floss to our clothes, but perhaps most disturbingly, they’re also found in our drinking water. In Poisoning the Well, The Hill staff writers Sharon Udasin and Rachel Frazin follow how PFAS got into our environment in the first place — a story of corporate greed and cover-ups that will be familiar to anyone aware of the fossil fuel playbook. Preorder it here.
Journalist Malcolm Harris’ last book was an “encyclopedic,” 700-page history of the city of Palo Alto, which became a fixture of best-of-the-year lists after it came out last February. Hot on its heels is Harris’ follow-up, What’s Left (which slow readers will be relieved to hear is less of a time commitment, at 320 pages). Harris’ intention with his new work is to explore “our remaining options for saving the world,” all of which involve varying degrees of collective action but which escalate from “progressive” to “socialist” to “revolutionary.” It’s one that you can be sure will have people talking. Preorder it here.
Alan Weisman’s hugely successful 2007 book, The World Without Us, speculated about humanity’s legacy if we suddenly disappeared. (Slate named it in 2019 as one of the 50 best nonfiction books in the past quarter-century.) Now, Weisman turns his attention to helping us stick around. “I am working on a book with kind of a vast topic, which is what are humanity’s best and most realistic hopes for getting through this very difficult century that we have,” he told Bangladesh’s Business Standard in 2022, while visiting the country during the research stage of his new project, Hope Dies Last. Weisman’s book took him all over the world — including the Korean de-militarized zone, the Netherlands, and the Marshall Islands — as he looked to speak with people across disciplines and professions about how we can approach our future. Bill McKibben has described the result as “a nonfiction companion to Kim Stanley Robinson’s Ministry for the Future.” Preorder it here.
In 1999, 24-year-old environmentalist Terence Unity Freitas traveled to Colombia to support the Indigenous U’wa people in resisting Occidental Petroleum, which was interested in drilling to extract some 1.5 billion barrels of oil from beneath the cloud forest. During what was supposed to be a weeklong visit, Freitas was kidnapped by the Armed Revolutionary Forces of Colombia (better known as FARC) along with two other Americans; their bodies were later found, bound and shot, just over the border in Venezuela. Twenty years later, Abby Reyes — the author of this memoir and Freitas’ partner at the time of his death — was recognized as a victim in Colombia’s truth and reconciliation process, resurfacing old griefs, reflections, and questions. “I bring the reader along in my demand for truth before the tribunal while awakening our collective awareness of what the truth demands of all of us in this era of ecological collapse and social transformation,” Reyes has said of her book. Preorder it here.
In Susanna Kwan’s debut novel, Awake in the Floating City, San Francisco is almost entirely underwater. Years of Biblical rain mean most people have already evacuated, but Bo — who lost her mother to the waters — lingers long past when sensible people have fled. Then one day, she receives a note from her neighbor, Mia, a 130-year-old woman who doesn’t want to leave the city, either; together, the two become the last people left in San Francisco. “What post-apocalyptic vision dares be so gorgeous?” marvels the author Meng Jin in one of the book’s early blurbs. Preorder it here.
Identical twin sister arborists teach the Women’s Tree Climbing Workshop. While that sounds like the beginning of a fairy tale, it’s the delightfully real-life starting point of journalist Marguerite Holloway’s Take to the Trees. “I was there to be in trees and to better understand them,” she writes of her attendance at the climbing workshop. “Trees and forests are facing existential threats because of climate change, but it can be a struggle to grasp the extent of the danger.” While not all of us have the time, ability, or inclination to take to such “gut-lurching” heights to learn more, we can read Take to the Trees, which records Holloway’s experience overcoming her fears and learning to appreciate the threat to American forests. Preorder it here.
Natural history is one of my favorite genres, and I’m especially excited for Sea of Grass by Minnesota Star Tribute journalists Dave Hage and Josephine Marcotty about one of the more neglected ecosystems of the genre: the American prairie. The grassland, which makes up a vast swath of the inner United States, is an incredible self-sustaining marvel — and nearly as biodiverse as a tropical rainforest. Yet many people today still either share European settlers’ disinterested view of the landscape or adopt a purely utilitarian one — which is why, after 200 years of plows, drainages, and nitrogen fertilizers, the effects have been “catastrophic.” Still, plenty of people who live on the prairie understand the importance of protecting such a special ecosystem, and Hage and Marcotty follow the effort to work alongside the land, not just against it. Sea of Grass earned a coveted blurb from McKibben, in which he calls the book “well worth the read.” Preorder it here.
We’ve been attempting to predict the weather for as long as humans have existed. Satellites, radars, and computers helped us make a significant leap forward from the days of farmer’s almanacs, but advances in artificial intelligence, drones, and the proliferation of home weather stations have created previously unimaginable opportunities for accuracy. (It’s a tech frontier we’ve covered quite a bit here at Heatmap, as well). In his book, Journalist Thomas E. Weber dives into the wild — and wildly important — world of forecasting, which will hit shelves just in time for hurricane season. Preorder it here.
Climate scientist and Shift Key guest Kate Marvel structured her highly anticipated first book around nine different emotional lenses for looking at climate change. That might seem like an odd angle for a scientist, since researchers are specifically taught not to bring emotion into their work. Still, she contends that just as there is no one way to feel about climate change, there is no one emotion we can tap to guide our response to it, either. From hope to pride to love, Marvel urges readers to get deep into their feels in Human Nature, which also touches on “Greek mythology,” “witches,” “geophysical fluid dynamics,” and “romantic comedies” — though according to Marvel, you won’t find “despair” in its pages. A 120,000-copy initial print run suggests the publisher, Ecco, believes this one will be a hit. Preorder it here.
Addressing climate change will require us to address how we eat, which accounts for a third of our carbon emissions. How to ameliorate that is one of the most significant questions we’re currently staring down as a species — and the topic of journalist and Heatmap contributor Michael Grunwald’s next book. Though the answers he finds might not always fit into our comfortable narratives — Grunwald recently ruffled feathers with a related piece for The New York Times defending industrial agriculture’s high yields on small parcels of land as our “best hope” — We Are Eating the Earth seems certain to reshape how its readers think about food, policy, and our thrice-daily consumptions. I can’t wait to be challenged by it. Preorder it here.
Science journalist Peter Brannen’s last book was about the five times life on our planet almost ended in mass extinctions. His follow-up, The Story of CO2 Is the Story of Everything, will zero in on the collection of molecules that have allowed life to exist in the first place. Of course, the great irony of carbon dioxide is that while it has made our planet habitable, fluctuations in its presence in the atmosphere are also responsible for things like almost killing our ancestors all off in an event known as the Great Dying — and now, of course, we have put our thumb on that scale. By looking backward, often by many millions of years, Brennen gives us a glimpse of our future. You’ll definitely want to preorder this book, if only because it will look great on the shelf next to Brennen’s other Eric Nyquist-designed cover. Preorder it here.

Citrine Informatics has been applying machine learning to materials discovery for years. Now more advanced models are giving the tech a big boost.
When ChatGPT launched three years ago, it became abundantly clear that the power of generative artificial intelligence had the capacity to extend far beyond clever chatbots. Companies raised huge amounts of funding based on the idea that this new, more powerful AI could solve fundamental problems in science and medicine — design new proteins, discover breakthrough drugs, or invent new battery chemistries.
Citrine Informatics, however, has largely kept its head down. The startup was founded long before the AI boom, back in 2013, with the intention of using simple old machine learning to speed up the development of more advanced, sustainable materials. These days Citrine is doing the same thing, but with neural networks and transformers, the architecture that undergirds the generative AI revolution.
“The technology transition we’re going through right now is pretty massive,” Greg Mulholland, Citrine’s founder and CEO, told me. “But the core underlying goal of the company is still the same: help scientists identify the experiments that will get them to their material outcome as fast as possible.”
Rather than developing its own novel materials, Citrine operates on a software-as-a-service model, selling its platform to companies including Rolls-Royce, EMD Electronics, and chemicals giant LyondellBassell. While a SaaS product may be less glamorous than independently discovering a breakthrough compound that enables something like a room-temperature superconductor or an ultra-high-density battery, Citrine’s approach has already surfaced commercially relevant materials across a variety of sectors, while the boldest promises of generative AI for science remain distant dreams.
“You can think of it as science versus engineering,” Mulholland told me. “A lot of science is being done. Citrine is definitely the best in kind of taking it to the engineering level and coming to a product outcome rather than a scientific discovery.” Citrine has helped to develop everything from bio-based lotion ingredients to replace petrochemical-derived ones, to plastic-free detergents, to more sustainable fire-resistant home insulation, to PFAS-free food packaging, to UV-resistant paints.
On Wednesday, the company unveiled two new platform capabilities that it says will take its approach to the next level. The first is essentially an advanced LLM-powered filing system that organizes and structures unwieldy materials and chemicals datasets from across a company. The second is an AI framework informed by an extensive repository of chemistry, physics, and materials knowledge. It can ingest a company’s existing data, and, even if the overall volume is small, use it to create a list of hundreds of potential new materials optimized for factors such as sustainability, durability, weight, manufacturability, or whatever other outcomes the company is targeting.
The platform is neither purely generative nor purely predictive. Instead, Mulholland explained, companies can choose to use Citrine’s tools “in a more generative mode” if they want to explore broadly and open up the field of possible materials discoveries, or in a more “optimized” mode that stays narrowly focused on the parameters they set. “What we find is you need a healthy blend of the two,” he told me.
The novel compounds the model spits out still need to be synthesized and tested by humans. “What I tell people is, any plane made of materials designed exclusively by Citrine and never tested is not a plane I’m getting on,” Mulholland told me. The goal isn’t to achieve perfection right out of the lab, but rather to optimize the experiments companies end up having to do. “We still need to prove materials in the real world, because the real world will complicate it.”
Indeed it will. For one thing, while AI is capable of churning out millions of hypothetical materials — as a tool developed by Google DeepMind did in 2023 — materials scientists have since shown that many are just variants of known compounds, while others are unstable, unable to be synthesized, or otherwise irrelevant under real world conditions.
Such failures likely stem, in part, from another common limitation of AI models trained solely on publicly available materials and chemicals data: Academic research tends to report only successful outcomes, omitting data on what didn’t work and which compounds weren’t viable. That can lead models to be overly optimistic about the magnitude and potential of possible materials solutions and generate unrealistic “discoveries” that may have already been tested and rejected.
Because Citrine’s platform is deployed within customer organizations, it can largely sidestep this problem by tuning its model on niche, proprietary datasets. These datasets are small when compared with the vast public repositories used to train Citrine’s base model, but the granular information they contain about prior experiments — both successes and failures — has proven critical to bringing new discoveries to market.
While the holy grail for materials science may be a model trained on all the world’s relevant data — public and private, positive and negative — at this point that’s just a fantasy, one of Citrine’s investors, Mark Cupta of Prelude Ventures, told me over email. “It’s hard to get buy-in from the entire material development world to make an open-source model that pulls in data from across the field.”
Citrine’s last raise, which Prelude co-led, came at the very beginning of 2023, as the AI wave was still gathering momentum. But Mulholland said there’s no rush to raise additional capital — in fact, he expects Citrine to turn a profit in the next year or so.
That milestone would strongly validate the company’s strategy, which banks on steady revenue from its subscription-based model to compensate for the fact that it doesn’t own the intellectual property for the materials it helps develop. While Mulholland told me that many players in this space are trying to “invent new materials and patent them and try to sell them like drugs,” Citriene is able to “invent things much more quickly, in a more realistic way than the pie in the sky, hoping for a Nobel Prize [approach].”
Citrines is also careful to assure that its model accounts for real world constraints such as regulations and production bottlenecks. Say a materials company is creating an aluminum alloy for an automaker, Mulholland explained — it might be critical to stay within certain elemental bounds. If the company were to add in novel elements, the automaker would likely want to put its new compound through a rigorous testing process, which would be annoying if it’s looking to get to market as quickly as possible. Better, perhaps, to tinker around the edges of what’s well understood.
In fact, Mulholland told me it’s often these marginal improvements that initially bring customers into the fold, convincing them that this whole AI-for-materials thing is more than just hype. “The first project is almost always like, make the adhesive a little bit stickier — because that’s a good way to prove to these skeptical scientists that AI is real and here to stay,” he said. “And then they use that as justification to invest further and further back in their product development pipeline, such that their whole product portfolio can be optimized by AI.”
Overall, the company says that its new framework can speed up materials development by 80%. So while Mulholland and Citrine overall may not be going for the Nobel in Chemistry, don’t doubt for a second that they’re trying to lead a fundamental shift in the way consumer products are designed.
“I’m as bullish as I can possibly be on AI in science,” Mulholland told me. “It is the most exciting time to be a scientist since Newton. But I think that the gap between scientific discovery and realized business is much larger than a lot of AI folks think.”
Plus more insights from Heatmap’s latest event Washington, D.C.
At Heatmap’s event, “Supercharging the Grid,” two members of the House of Representatives — a California Democrat and a Colorado Republican — talked about their shared political fight to loosen implementation of the National Environmental Policy Act to accelerate energy deployment.
Representatives Gabe Evans and Scott Peters spoke with Heatmap’s Robinson Meyer at the Washington, D.C., gathering about how permitting reform is faring in Congress.
“The game in the 1970s was to stop things, but if you’re a climate activist now, the game is to build things,” said Peters, who worked as an environmental lawyer for many years. “My proposal is, get out of the way of everything and we win. Renewables win. And NEPA is a big delay.”
NEPA requires that the federal government review the environmental implications of its actions before finalizing them, permitting decisions included. The 50-year-old environmental law has already undergone several rounds of reform, including efforts under both Presidents Biden and Trump to remove redundancies and reduce the size and scope of environmental analyses conducted under the law. But bottlenecks remain — completing the highest level of review under the law still takes four-and-a-half years, on average. Just before Thanksgiving, the House Committee on Natural Resources advanced the SPEED Act, which aims to ease that congestion by creating shortcuts for environmental reviews, limiting judicial review of the final assessments, and preventing current and future presidents from arbitrarily rescinding permits, subject to certain exceptions.
Evans framed the problem in terms of keeping up with countries like China on building energy infrastructure. “I’ve seen how other parts of the world produce energy, produce other things,” said Evans. “We build things cleaner and more responsibly here than really anywhere else on the planet.”
Both representatives agreed that the SPEED Act on its own wouldn’t solve all the United States’ energy issues. Peters hinted at other permitting legislation in the works.
“We want to take that SPEED Act on the NEPA reform and marry it with specific energy reforms, including transmission,” said Peters.
Next, Neil Chatterjee, a former Commissioner of the Federal Energy Regulatory Commission, explained to Rob another regulatory change that could affect the pace of energy infrastructure buildout: a directive from the Department of Energy to FERC to come up with better ways of connecting large new sources of electricity demand — i.e. data centers — to the grid.
“This issue is all about data centers and AI, but it goes beyond data centers and AI,” said Chatterjee. “It deals with all of the pressures that we are seeing in terms of demand from the grid from cloud computing and quantum computing, streaming services, crypto and Bitcoin mining, reshoring of manufacturing, vehicle electrification, building electrification, semiconductor manufacturing.”
Chatterjee argued that navigating load growth to support AI data centers should be a bipartisan issue. He expressed hope that AI could help bridge the partisan divide.
“We have become mired in this politics of, if you’re for fossil fuels, you are of the political right. If you’re for clean energy and climate solutions, you’re the political left,” he said. “I think AI is going to be the thing that busts us out of it.”
Updating and upgrading the grid to accommodate data centers has grown more urgent in the face of drastically rising electricity demand projections.
Marsden Hanna, Google’s head of energy and dust policy, told Heatmap’s Jillian Goodman that the company is eyeing transmission technology to connect its own data centers to the grid faster.
“We looked at advanced transition technologies, high performance conductors,” said Hanna. “We see that really as just an incredibly rapid, no-brainer opportunity.”
Advanced transmission technologies, otherwise known as ATTs, could help expand the existing grid’s capacity, freeing up space for some of the load growth that economy-wide electrification and data centers would require. Building new transmission lines, however, requires permits — the central issue that panelists kept returning to throughout the event.
Devin Hartman, director of energy and environmental policy at the R Street Institute, told Jillian that investors are nervous that already-approved permits could be revoked — something the solar industry has struggled with under the Trump administration.
“Half the battle now is not just getting the permits on time and getting projects to break ground,” said Hartman. “It’s also permitting permanence.”
This event was made possible by the American Council on Renewable Energy’s Macro Grid Initiative.
On gas turbine backorders, Europe’s not-so-green deal, and Iranian cloud seeding
Current conditions: Up to 10 inches of rain in the Cascades threatens mudslides, particularly in areas where wildfires denuded the landscape of the trees whose roots once held soil in place • South Africa has issued extreme fire warnings for Northern Cape, Western Cape, and Eastern Cape • Still roiling from last week’s failed attempt at a military coup, Benin’s capital of Cotonou is in the midst of a streak of days with temperatures over 90 degrees Fahrenheit and no end in sight.

Exxon Mobil Corp. plans to cut planned spending on low-carbon projects by a third, joining much of the rest of its industry in refocusing on fossil fuels. The nation’s largest oil producer said it would increase its earnings and cash flow by $5 billion by 2030. The company projected earnings to grow by 13% each year without any increase in capital spending. But the upstream division, which includes exploration and production, is expected to bring in $14 billion in earnings growth compared to 2024. The key projects The Wall Street Journal listed in the Permian Basin, Guyana and at liquified natural gas sites would total $4 billion in earnings growth alone over the next five years. The announcement came a day before the Department of the Interior auctioned off $279 million of leases across 80 million acres of federal waters in the Gulf of Mexico.
Speaking of oil and water, early Wednesday U.S. armed forces seized an oil tanker off the coast of Venezuela in what The New York Times called “a dramatic escalation in President Trump’s pressure campaign against Nicolás Maduro.” When asked what would become of the vessel's oil, Trump said at the White House, “Well, we keep it, I guess.”
The Federal Reserve slashed its key benchmark interest rate for the third time this year. The 0.25 percentage point cut was meant to calibrate the borrowing costs to stay within a range between 3.5% and 3.75%. The 9-3 vote by the central bank’s board of governors amounted to what Wall Street calls a hawkish cut, a move to prop up a cooling labor market while signaling strong concerns about future downward adjustments that’s considered so rare CNBC previously questioned whether it could be real. But it’s good news for clean energy. As Heatmap’s Matthew Zeitlin wrote after the September rate cut, lower borrowing costs “may provide some relief to renewables developers and investors, who are especially sensitive to financing costs.” But it likely isn’t enough to wipe out the effects of Trump’s tariffs and tax credit phaseouts.
GE Vernova plans to increase its capacity to manufacture gas turbines by 20 gigawatts once assembly line expansions are completed in the middle of next year. But in a presentation to investors this week, the company said it’s already sold out of new gas turbines all the way through 2028, and has less than 10 gigawatts of equipment left to sell for 2029. It’s no wonder supersonic jet startups, as I wrote about in yesterday’s newsletter, are now eyeing a near-term windfall by getting into the gas turbine business.

The European Union will free more than 80% of the companies from environmental reporting rules under a deal struck this week. The agreement between EU institutions marks what Politico Europe called a “major legislative victory” for European Commission President Ursula von der Leyen, who has sought to make the bloc more economically self-sufficient by cutting red tape for business in her second term in office. The rollback is also a win for Trump, whose administration heavily criticized the EU’s green rules. It’s also a victory for the U.S. president’s far-right allies in Europe. The deal fractured the coalition that got the German politician reelected to the EU’s top job, forcing her center-right faction to team up with the far right to win enough votes for secure victory.
Ravaged by drought, Iran is carrying out cloud-seeding operations in a bid to increase rainfall amid what the Financial Times clocked as “the worst water crisis in six decades.” On Tuesday, Abbas Aliabadi, the energy minister, said the country had begun a fresh round of injecting crystals into clouds using planes, drones, and ground-based launchers. The country has even started developing drones specifically tailored to cloud seeding.

In a press release, the company said its vehicles would hit the streets by next year.
