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.

Predicting the location and severity of thunderstorms is at the cutting edge of weather science. Now funding for that science is at risk.
Tropical Storm Barry was, by all measures, a boring storm. “Blink and you missed it,” as a piece in Yale Climate Connections put it after Barry formed, then dissipated over 24 hours in late June, having never sustained wind speeds higher than 45 miles per hour. The tropical storm’s main impact, it seemed at the time, was “heavy rains of three to six inches, which likely caused minor flooding” in Tampico, Mexico, where it made landfall.
But a few days later, U.S. meteorologists started to get concerned. The remnants of Barry had swirled northward, pooling wet Gulf air over southern and central Texas and elevating the atmospheric moisture to reach or exceed record levels for July. “Like a waterlogged sponge perched precariously overhead, all the atmosphere needed was a catalyst to wring out the extreme levels of water vapor,” meteorologist Mike Lowry wrote.
More than 100 people — many of them children — ultimately died as extreme rainfall caused the Guadalupe River to rise 34 feet in 90 minutes. But the tragedy was “not really a failure of meteorology,” UCLA and UC Agriculture and Natural Resources climate scientist Daniel Swain said during a public “Office Hours” review of the disaster on Monday. The National Weather Service in San Antonio and Austin first warned the public of the potential for heavy rain on Sunday, June 29 — five days before the floods crested. The agency followed that with a flood watch warning for the Kerrville area on Thursday, July 3, then issued an additional 21 warnings, culminating just after 1 a.m. on Friday, July 4, with a wireless emergency alert sent to the phones of residents, campers, and RVers along the Guadalupe River.
The NWS alerts were both timely and accurate, and even correctly predicted an expected rainfall rate of 2 to 3 inches per hour. If it were possible to consider the science alone, the official response might have been deemed a success.
Of all the storm systems, convective storms — like thunderstorms, hail, tornadoes, and extreme rainstorms — are some of the most difficult to forecast. “We don’t have very good observations of some of these fine-scale weather extremes,” Swain told me after office hours were over, in reference to severe meteorological events that are often relatively short-lived and occur in small geographic areas. “We only know a tornado occurred, for example, if people report it and the Weather Service meteorologists go out afterward and look to see if there’s a circular, radial damage pattern.” A hurricane, by contrast, spans hundreds of miles and is visible from space.
Global weather models, which predict conditions at a planetary scale, are relatively coarse in their spatial resolution and “did not do the best job with this event,” Swain said during his office hours. “They predicted some rain, locally heavy, but nothing anywhere near what transpired.” (And before you ask — artificial intelligence-powered weather models were among the worst at predicting the Texas floods.)
Over the past decade or so, however, due to the unique convective storm risks in the United States, the National Oceanic and Atmospheric Administration and other meteorological agencies have developed specialized high resolution convection-resolving models to better represent and forecast extreme thunderstorms and rainstorms.
NOAA’s cutting-edge specialized models “got this right,” Swain told me of the Texas storms. “Those were the models that alerted the local weather service and the NOAA Weather Prediction Center of the potential for an extreme rain event. That is why the flash flood watches were issued so early, and why there was so much advanced knowledge.”
Writing for The Eyewall, meteorologist Matt Lanza concurred with Swain’s assessment: “By Thursday morning, the [high resolution] model showed as much as 10 to 13 inches in parts of Texas,” he wrote. “By Thursday evening, that was as much as 20 inches. So the [high resolution] model upped the ante all day.”

To be any more accurate than they ultimately were on the Texas floods, meteorologists would have needed the ability to predict the precise location and volume of rainfall of an individual thunderstorm cell. Although models can provide a fairly accurate picture of the general area where a storm will form, the best current science still can’t achieve that level of precision more than a few hours in advance of a given event.
Climate change itself is another factor making storm behavior even less predictable. “If it weren’t so hot outside, if it wasn’t so humid, if the atmosphere wasn’t holding all that water, then [the system] would have rained and marched along as the storm drifted,” Claudia Benitez-Nelson, an expert on flooding at the University of South Carolina, told me. Instead, slow and low prevailing winds caused the system to stall, pinning it over the same worst-case-scenario location at the confluence of the Hill Country rivers for hours and challenging the limits of science and forecasting.
Though it’s tempting to blame the Trump administration cuts to the staff and budget of the NWS for the tragedy, the local NWS actually had more forecasters on hand than usual in its local field office ahead of the storm, in anticipation of potential disaster. Any budget cuts to the NWS, while potentially disastrous, would not go into effect until fiscal year 2026.
The proposed 2026 budget for NOAA, however, would zero out the upkeep of the models, as well as shutter the National Severe Storms Laboratory in Norman, Oklahoma, which studies thunderstorms and rainstorms, such as the one in Texas. And due to the proprietary, U.S.-specific nature of the high-resolution models, there is no one coming to our rescue if they’re eliminated or degraded by the cuts.
The impending cuts are alarming to the scientists charged with maintaining and adjusting the models to ensure maximum accuracy, too. Computationally, it’s no small task to keep them running 24 hours a day, every day of the year. A weather model doesn’t simply run on its own indefinitely, but rather requires large data transfers as well as intakes of new conditions from its network of observation stations to remain reliable. Although the NOAA high-resolution models have been in use for about a decade, yearly updates keep the programs on the cutting edge of weather science; without constant tweaks, the models’ accuracy slowly degrades as the atmosphere changes and information and technologies become outdated.
It’s difficult to imagine that the Texas floods could have been more catastrophic, and yet the NOAA models and NWS warnings and alerts undoubtedly saved lives. Still, local Texas authorities have attempted to pass the blame, claiming they weren’t adequately informed of the dangers by forecasters. The picture will become clearer as reporting continues to probe why the flood-prone region did not have warning sirens, why camp counselors did not have their phones to receive overnight NWS alarms, why there were not more flood gauges on the rivers, and what, if anything, local officials could have done to save more people. Still, given what is scientifically possible at this stage of modeling, “This was not a forecast failure relative to scientific or weather prediction best practices. That much is clear,” Swain said.
As the climate warms and extreme rainfall events increase as a result, however, it will become ever more crucial to have access to cutting-edge weather models. “What I want to bring attention to is that this is not a one-off,” Benitez-Nelson, the flood expert at the University of South Carolina, told me. “There’s this temptation to say, ‘Oh, it’s a 100-year storm, it’s a 1,000-year storm.’”
“No,” she went on. “This is a growing pattern.”
On the Texas floods, wind and solar restrictions, and an executive order
Current conditions: An extreme heat warning is in place for Phoenix, which could reach 113 degrees Fahrenheit today • Flooding in central North Carolina has killed at least one person after two months’ worth of rain fell in 24 hours • Parts of the U.K. this week will experience their third heatwave in less than a month.
The catastrophic flooding in central Texas that claimed more than 100 lives late last week was intensified by human-driven climate change, according to a rapid attribution report by ClimaMeter, an experimental framework funded by the European Union and the French National Centre for Scientific Research. The researchers compared historic and contemporary weather patterns in Texas’ Hill Country and found that conditions going into Fourth of July weekend were up to 7% wetter than during similar events in the past. “These results suggest that meteorological conditions similar to those of the July 2025 Texas floods are becoming more favorable for extreme precipitation, in line with what would be expected under continued global warming,” the researchers wrote, concluding that “natural variability alone cannot explain the changes in precipitation associated with this very exceptional meteorological condition.”
The development of new wind and solar power plants is “now heavily restricted or outright banned in about one in five counties across the country,” according to a major new survey of public records and local ordinances by my colleagues Robinson Meyer and Charlie Clynes. Their report found bans and restrictions — such as a rule that wind turbines must be placed a certain number of miles from homes, or that solar farms cannot take up more than 1% of a county’s agricultural land — in a total of 605 U.S. counties, including at least 59 municipalities in the more-renewables-friendly Northeast. In total, the bans and restrictions on renewables cover approximately 17% of the continental United States’ total land mass.
Robinson and Charlie’s findings have not been previously reported, and their research involved calling thousands of counties where laws, in some cases, were not in existing public databases. You can access the full project- and county-level data and associated risk assessments via Heatmap Pro, here.
In an executive order on Monday, President Trump directed the Treasury Department to issue “new and revised guidance” restricting which projects will still qualify for wind and solar tax credits. The order builds on the repeal of renewable energy tax credits in the One Big Beautiful Bill Act, which had stipulated that such projects would need to begin construction within a year and come online by 2028 to be eligible for the subsidies. Now the government will take a stricter approach to defining “the beginning of construction” to prevent “the artificial acceleration or manipulation of eligibility” by limiting credits to projects in which “a substantial portion of a subject facility has been built.”
Freedom Caucus members had described the tax credits as a sticking point during their late negotiations over the bill. As my colleagues Jael Holzman and Katie Brigham previously reported, North Carolina Republican Representative Ralph Norman alluded to a conversation with Trump in which the president had assured him that he was “going to deal with [the tax credits] in his own way.” It appears the executive order is the follow-through on that promise. Additionally, Trump’s executive order called for the Department of the Interior to determine whether any of its policies, practices, or regulations “provide preferential treatment to wind and solar facilities in comparison to dispatchable energy sources” and revise them accordingly.
An Energy Department report released Monday warned that blackouts in the U.S. could “increase by 100% in 2030” if the country continues to close its coal and natural gas power plants. The report, completed at the direction of an April executive order by President Trump, anticipates 209 gigawatts of new generation by 2030 to replace 104 gigawatts of retirements — but “only 22 gigawatts would come from firm baseload generation sources,” so that, “even assuming no retirements, the model found increased risk of outages in 2030 by a factor of 34.” The DOE concluded that the U.S. grid “will not be able to sustain the combined impact of coal and other plant closures, an overreliance on intermittent energy sources like wind and solar, and data center growth, highlighting the urgency of increasing dispatchable energy output.”
The DOE’s report sets the stage for the department to continue to prevent the phase-out of old fossil fuel power plants and open new facilities. Many are skeptical of the agency’s logic, however, pointing to renewable-heavy grid success stories like Texas. The Department of Energy “appears to exaggerate the risk of blackouts and undervalue the contributions of entire resource classes, like wind, solar, and battery storage,” Caitlin Marquis, the managing director at Advanced Energy United, said, per Axios.
On Monday, the Trump administration sent letters to 14 countries warning them they’ll face tariffs of up to 40% if they don’t reach a trade deal with the U.S. by an August 1 deadline. Significantly, automaking giants Japan and South Korea — which each account for about 4% of U.S. imports, per The New York Times — were among the recipients, and face 25% tariffs according to the letters. As my colleague Jael Holzman previously reported, Japan in particular had been “positioned to be an ally in U.S. efforts to wean off China-linked minerals and signed a minerals trade agreement under Biden,” with the imposition of such tariffs potentially threatening to tank America’s own “mineral supply chain renaissance.”

The Seine River opened for swimming last weekend for the first time since 1923, following an extensive effort to upgrade the city’s sewer systems and water treatment facilities. “I never imagined being in the water close to the Eiffel Tower,” one swimmer told Reuters.

The flash floods in Central Texas are expected to become one of the deadliest such events in the past 100 years, with authorities updating the death toll to 82 people on Sunday night. Another 41 people are still missing after the storms, which began Thursday night and raised the Guadalupe River some 26 feet in less than an hour, providing little chance for holiday weekend campers and RVers to escape.
Although it’s far too soon to definitively attribute the disaster to climate change, a warmer atmosphere is capable of holding more moisture and producing heavy bursts of life-threatening rainfall. Disasters like the one in Texas are one of the “hardest things to predict that’s becoming worse faster than almost anything else in a warming climate, and it’s at a moment where we’re defunding the ability of meteorologists and emergency managers to coordinate,” Daniel Swain of the University of California Agriculture and Natural Resources told the Los Angeles Times. Meteorologists who spoke to Wired argued that the National Weather Service “accurately predicted the risk of flooding in Texas and could not have foreseen the extreme severity of the storm” ahead of the event, while The New York Times noted that staffing shortages at the agency following President Trump’s layoffs potentially resulted in “the loss of experienced people who would typically have helped communicate with local authorities in the hours after flash flood warnings were issued overnight.”
President Trump announced this weekend that his administration plans to send up to 15 letters on Monday to important trade partners detailing their tariff rates. Though Trump didn’t specify which countries would receive such letters or what the rates could be, he said the tariffs would go into effect on August 1 — an extension from the administration’s 90-day pause through July 9 — and range “from maybe 60% or 70% tariffs to 10% and 20% tariffs.” Treasury Secretary Scott Bessent added on CNN on Sunday that the administration would subsequently send an additional round of letters to 100 less significant trade partners, warning them that “if you don’t move things along” with trade negotiations, “then on August 1, you will boomerang back to your April 2 tariff level.” Trump’s proposed tariffs have already rattled industries as diverse as steel and aluminum, oil, plastics, agriculture, and bicycles, as we’ve covered extensively here at Heatmap. Trump’s weekend announcement also sent jitters through global markets on Monday morning.
President Trump’s gutting of the Inflation Reduction Act with the signing of the budget reconciliation bill last week will add an extra 7 billion tons of emissions to the atmosphere by 2030, a new analysis by Climate Brief has found. The rollback on renewable energy credits and policy means that “U.S. emissions are now set to drop to just 3% below current levels by 2030 — effectively flatlining — rather than falling 40% as required to hit the now-defunct [Paris Agreement] target,” Carbon Brief notes. As a result, the U.S. will be about 2 billion tons short of its emissions goal by 2030, adding an emissions equivalent of “roughly the annual output of Indonesia, the world’s sixth-largest emitter.”
To reach its conclusions, Carbon Brief utilized modeling by Princeton University’s REPEAT Project, which examined how the current obstacles facing U.S. wind and solar energy will impact U.S. emissions targets, as well as the likely slowdown in electric vehicle sales and energy efficiency upgrades due to the removal of subsidies. “Under this new set of U.S. policies, emissions are only expected to be 20% lower than 2005 levels by 2030,” Carbon Brief writes.
Engineering giant SKF announced late last week that it had set a new world record for tidal turbine reliability, with its systems in northern Scotland having operated continuously for over six years at 1.5 megawatts “without the need for unplanned or disruptive maintenance.” The news represents a significant milestone for the technology since “harsh conditions, high maintenance, and technical challenges” have traditionally made tidal systems difficult to implement in the real world, Interesting Engineering notes. The pilot program, MayGen, is operated by SAE Renewables and aims, as its next step, to begin deploying 3-megawatt powertrains for 30 turbines across Scotland, France, and Japan starting next year.
Satellites monitoring the Southern Ocean have detected for the first time a collapse and reversal of a major current in the Atlantic Meridional Overturning Circulation. “This is an unprecedented observation and a potential game-changer,” said physicist Marilena Oltmanns, the lead author of a paper on the finding, adding that the changes could “alter the Southern Ocean’s capacity to sequester heat and carbon.”
A breakthrough in satellite ocean observation technology enabled scientists to recognize that, since 2016, the Southern Ocean has become saltier, even as Antarctic sea ice has melted at a rate comparable to the loss of Greenland’s ice. The two factors have altered the Southern Ocean’s properties like “we’ve never seen before,” Antonio Turiel, a co-author of the study, explained. “While the world is debating the potential collapse of the AMOC in the North Atlantic, we’re seeing that the Southern Ocean is drastically changing, as sea ice coverage declines and the upper ocean is becoming saltier,” he went on. “This could have unprecedented global climate impacts.” Read more about the oceanic feedback loop and its potential global consequences at Science Daily, here.
The French public research university Sciences Po will open the Paris Climate School in September 2026, making it the first school in Europe to offer a “degree in humanities and social sciences dedicated to ecological transition.” The first cohort will comprise 100 master’s students in an English-language program. “Faced with the ecological emergency, it is essential to train a new generation of leaders who can think and act differently,” said Laurence Tubiana, the dean of the Paris Climate School.
