New research published today in Nature shocked even the study’s own authors.
Hurricane Helene is, by conventional measures, the deadliest hurricane to strike the continental United States since Katrina. At least 182 people have been confirmed killed by the storm, with hundreds of people still unaccounted for. Although all hurricanes are deadly, only a handful of storms have killed more than 100 people since 1950. Or at least that is what we have long thought. New research suggests that these conventional tallies may be a vast undercount.
Several years ago, two economists and public policy researchers — Rachel Young and Solomon Hsiang, now of Princeton and Stanford — began to study a seemingly simple question: How many Americans do hurricanes kill each year? According to the federal government, the average hurricane kills 24 people after making landfall. That seemed likely to be a modest underestimate. Economists know that natural disasters can have a long tail of suffering; Hsiang expected the real number to be a “single digit multiple” of that figure — perhaps 50 or 100 people per storm.
Yet when they ran the numbers and looked at mortality in places affected by storms, they were initially perplexed by the results, Hsiang told me earlier this week. The numbers they came up with didn’t even make sense at first.
“It was months of us trying to understand what we were looking at,” Hsiang said. “And then once we realized what we were seeing, it was years of us checking our work to find what we missed.” Only when it was clear that their work resembled other American public health statistics — specifically, that the white-Black mortality mirrored what has been found in other studies — that the horrifying truth sunk in.
The finding: Hurricanes are hundreds of times deadlier than anyone has realized.
Their study, which was published on Wednesday in Nature, finds that the average hurricane kills 7,000 to 11,000 people after making landfall in the United States. These previously uncounted deaths happened not during a storm or in its immediate aftermath, but as a long, slow trickle of mortality that plagues a region long after the clouds have cleared and floods have abated.
In any one year, the number of storm-related deaths is not very high. And yet a wave of excess deaths is visible in population data for at least 15 years after a storm hits an area, they found.
“It lasts for so many years, and because there’s so many storms hitting so many states, once you add up, it becomes this enormous number,” Hsiang told me. When added together, hurricanes’ long-term death toll exceeds American combat deaths in all wars, combined. The number so dwarfs previous estimates that it suggests tropical cyclones alone are a major determinant of public health across the United States.
Kerry Emanuel, an MIT meteorology professor who studies climate change and hurricanes, told me that the results were “truly astounding” and “persuasive,” although he noted that he is not an expert in the statistical approach used in the paper.
“Summed over all hurricanes, this amounts to three to five percent of all deaths near the Atlantic coast,” he said. “I expect this result will prove controversial and will be followed up by many other studies of long-term mortality from natural disasters.”
The paper fits into a growing body of research on what others have called the hidden or invisible public health threat of environmental threats. For years, researchers have known that air pollution and heat waves, seemingly silent hazards, can in fact kill tens of thousands of people. Lately they have begun to apply the same techniques to other hazards, with outsized results.
Officially, Hurricane Maria killed 64 people when it struck Puerto Rico in 2017. But when researchers surveyed households across the island months after the storm, they found the death toll was closer to 4,600. (The territory’s government later revised the official figure to 2,975.) These deaths were caused not by the cyclone’s high winds or torrential floods, but rather by secondary effects of the storm’s destruction. Maria took out the island’s power grid and road networks, for instance, and preventing people with heart attacks and strokes from reaching the hospital in time.
That paper was written six months after Maria struck the island; this new hurricane paper considers a wider time horizon, finding that more than 80,000 Americans die each year as a result of a hurricane, whenever it occurred. Black people were disproportionately killed by the aftermath of hurricanes, at least partly because a larger share of the country’s Black population lives in storm-afflicted areas. About 37,000 white deaths each year are due to a prior tropical cyclone.
How could such storms cause such a long tail of deaths, affecting areas 10 or 15 years after they come ashore? The paper cannot answer those questions today. But Hsiang and Young hypothesize that hurricanes cause extreme economic distress, which can resonate for years or decades afterward. “If someone suffers a loss and can’t invest in their business, then it will have ramifications for their income long into the future,” Hsiang told me. “If someone is on a fixed income and their garage is destroyed, and they pull from their retirement funds to fix the garage, then eight years later when they face a big medical decision, they might choose” a cheaper or less effective form of treatment.
“When you talk to people, you hear stories like this,” Hsiang added. The time and money invested in dealing with the storm is often a “pure loss,” even if some of the damage ultimately gets reimbursed. “Even if you have insurance, that just means you already paid for it in some way,” he said.
Storms cause disruption in other ways. They can break up communities and social networks. (If children move away, for instance, their parent can face higher medical bills.) Hurricanes can also impose high costs on states, towns, and cities, which may then have to reduce or restrict other services as a result.
“When you think about how communities rebuild — local municipalities and states — they also play a lot of games with their budget” in the aftermath of a storm, Hsiang said. “If they spend a lot of money to rebuild a bridge or boardwalk somewhere, does that come out of some social program 10 years later? Or building a new NICU hospital?” That could explain why an infant — even one born 15 years after a storm struck a given area — could face a higher chance of death.
Young and Hsiang think that these economic drivers are most likely to be the big reason for the excess deaths — the effect is just too big and drawn out to make any other cause likely — but other possibilities exist, they recognize. Hurricanes could be deadly simply because they are highly stressful events. “We see an effect on cancer rates and also cardiovascular illness. Stress matters a lot to those,” Hsiang said. It’s also possible that hurricanes unleash contamination into the environment that then makes people sick. A flooded basement can become a breeding ground for mold. “There’s gas stations in every town. What chemicals come out when there’s flooding?” Hsiang wondered.
The paper may also help resolve a riddle in American public health. On average, Americans die earlier in the eastern half of the continental United States than in the western half. This effect is worst in the Gulf Coast and Southeast but persists to some degree in the Mid-Atlantic and Northeast.
The paper suggests that hurricanes may have something to do with this geographic phenomenon. For infants, people below the age of 44, and Black people of all ages, hurricanes may explain a large share but not all of the mortality gap.

It’s already conquered solar, batteries, and EVs. With a $2 billion new turbine factory in Scotland, it may have set its next target.
Batteries, solar panels, electric vehicles. The story of renewable energy deployment globally is increasingly one of China’s fiercely competitive domestic industries and deep supply chains exporting their immense capacity globally. Now, it may be wind’s turn.
The Chinese turbine manufacturer Ming Yang announced last week that it plans to invest $2 billion in a factory in Scotland. The facility is scheduled to start production in late 2028, churning out offshore wind equipment for use in the United Kingdom, which has over 15 gigawatts of offshore wind capacity, as well as for export, likely in Europe.
The deal comes as China finds itself at a kind of domestic clean energy crossroads, in terms of both supply and demand. On the former, the country has launched a campaign aimed at softening the cutthroat domestic competition, overproduction, and price wars that have defined many of its green industries, especially electric vehicles.
At the same time, China is setting out to alter its electricity markets to put renewable energy on a more market-based footing, while also paying coal-fired power plants to stay on the grid, as University of California, San Diego researcher Michael Davidson explained on a recent episode of Shift Key. These changes in electricity markets will reduce payments to solar and wind producers, making foreign markets potentially more attractive.
“We anticipate Chinese original equipment manufacturers will intensify their push toward international expansion, with Mingyang’s planned investment a signal of this trend,” Morningstar analyst Tancrede Fulop wrote in a note to clients. “This poses a challenge for Western incumbents, as Chinese players can capitalize on their cost advantages in a market driven by price.”
Ironically, Fulop said, the market changes will make the Chinese market more like Europe’s, which has become more price conscious as the market has matured and reductions in cost have slowed or outright stopped. “The transition is expected to make renewable developers increasingly price-sensitive as they seek to preserve project returns, ultimately weighing on wind turbine manufacturers’ profitability,” he wrote.
There’s a “cliff” coming in Chinese renewable energy deployment, Kyle Chan, a postdoctoral researcher at Princeton University, told me. “Overall, the net effect is expected to be a pretty sharp drop, and we’re already starting to see some of the effects of that.”
And turbine manufacturers would not be the first Chinese renewable industry to show up in Europe.
“There’s already an existing model” for Chinese manufacturers to set up shop in Western countries, Chan said. Chinese companies are already planning to manufacture solar modules in France, while Chinese EV maker BYD’s is planning factories in Hungary, Turkey, and potentially Spain.
China as a whole is responsible for over half of all new offshore wind capacity added in 2024, according to Global Energy Monitor, and has been growing at a 41% annual rate for the past five years. The energy intelligence firm Rystad estimates that China will make up 45% of all offshore wind capacity by 2030. Ming Yang itself claims to be behind almost a third of new offshore wind capacity built last year.
Meanwhile, offshore wind projects in the West — especially the United States — have faced the omnicrisis of high interest rates, backed-up supply chains, and Donald Trump. News of Ming Yang’s Scotland factory sent yet another shock through the ailing Western offshore wind market, with shares in the Danish company Vestas down 4% when the market opened Monday.
But with Chinese products and Chinese investment comes controversy and nerves among European political leaders. “There’re questions about tech transfer and job creation,” Chan said. “They also face some security issues and potential political backlash.”
In August, the German asset manager Luxcara announced that it would use Siemens Gamesa turbines for a planned offshore wind project instead of Ming Yang ones after backlash from German defense officials. “We see this as further evidence that a Chinese entry into the European wind market remains challenging,” analysts at Jefferies wrote to clients in August.
They were right to be skeptical — Chinese turbines’ entry into the European market has been long predicted and yet remains unrealized. “China’s increasingly cheap wind turbines could open new markets,” S&P Global Insights wrote in 2022, citing the same cost advantages as Morningstar did in reference to the Ming Yang factory announcement.
“China was already trying to angle into the European market,” Chan told me, seeing it as comparable to the U.S. in size and potentially more open to Chinese investment. “If they were kind of thinking about it before, now it’s gotten a greater sense of commercial urgency because I think the expectation is that their profit margins are really going to get squeezed.”
While China leads the world in building out renewable energy capacity domestically and exporting technology abroad, it has “decided not to decide” on pursuing a rapid, near-term decarbonization, Johns Hopkins University China scholar Jeremy Wallace recently argued in Heatmap.
While that means that the Paris Agreement goals are even farther out of reach, it may be fine for Chinese industries, including wind, as they look to sell abroad.
“Chinese firms have lots of reasons to want to build things abroad: Diversification away from the Chinese market, the zero or negative profits from selling domestically, and geopolitical balancing,” Wallace told me.
“If Brits want to have their citizens making the turbines that will power the country,” Wallace said, “this seems like a reasonable opportunity.”

The Department of Energy notified workers in multiple offices Friday that they were likely to be fired or reassigned to another part of the agency, E&E News reported Tuesday. Staffers at the Office of Clean Energy Demonstrations and the Office of State and Community Energy Programs received notices stating that the offices would “be undergoing a major reorganization and your position may be reassigned to another organization, transferred to another function or abolished.” Still, the notice said “no determination has been made concerning your specific position” just yet.
At least five offices received “general reduction in force notices,” as opposed to official notification of a reduction in force, according to a Latitude Media report. These included the Office of Clean Energy Demonstrations, the Office of Energy Efficiency and Renewable Energy, the Office of State and Community Energy Plans, and the Office of Fossil Energy. Nearly 200 Energy Department employees received direct layoff notices.
Catastrophic floods brought on by the remnants of a typhoon devastated the Alaska Native village of Kipnuk on Sunday. Five months ago, the Trump administration canceled a $20 million grant intended to protect the community against exactly this kind of extreme flooding, The New York Times reported Tuesday. The grant from the Environmental Protection Agency was meant to stabilize the riverbank on which Kipnuk is built. But in May, the agency yanked back the Biden-era grant, which EPA Administrator Lee Zeldin said was “no longer consistent” with the government’s priorities. In a post on X, Zeldin said the award was part of "wasteful DEI and Environmental Justice grants,” suggesting the funding was part of an ideological push for diversity, equity, and inclusion rather than a practical infrastructure boost to an Indigenous community facing serious challenges.
Zealan Hoover, a Biden-era senior adviser at the EPA, accused Zeldin of using “inflammatory rhetoric” that misrepresented the efforts in places like Kipnuk. “For decades, E.P.A. has been a partner to local communities,” Hoover said. “For the first time under this administration, E.P.A. has taken an aggressively adversarial posture toward the very people and communities that it is intended to protect.”

Late last Thursday, Heatmap’s Jael Holzman observed that the status of the 6.2-gigawatt Esmeralda 7, the nation’s largest solar project, had changed on the Bureau of Land Management’s website to “canceled.” The news sent shockwaves nationwide and drew blowback even from Republicans, including Utah Governor Spencer Cox, as I reported in this newsletter. Now, however, the bureau’s parent agency is denying that it made the call to cancel the project. “During routine discussions prior to the lapse in appropriations, the proponents and BLM agreed to change their approach for the Esmeralda 7 Solar Project in Nevada,” a spokesperson for the Department of the Interior told Utility Dive. “Instead of pursuing a programmatic level environmental analysis, the applicants will now have the option to submit individual project proposals to the BLM to more effectively analyze potential impacts.”
That means the project could still move forward with a piecemeal approach to permitting rather than one overarching approval, which aligns with what one of the developers involved told Jael last week. A representative for NextEra said that it is “in the early stage of development” with its portion of the Esmeralda 7 mega-project, and that the company is “committed to pursuing our project’s comprehensive environmental analysis by working closely with the Bureau of Land Management.” Still, the move represents a devastating setback for the solar installation, which may never fully materialize.
Ethane exports are rising as export capacity soars.EIA
U.S. exports of ethane, a key petrochemical feedstock extracted from raw natural gas during processing, are on track for “significant growth” through 2026, according to new analysis from the Energy Information Administration. Overseas sales are projected to grow 14% this year compared to the previous year, and another 16% next year. Ethane is mostly used as a feedstock for ethylene, a key ingredient in plastics, resins, and synthetic rubber. China has been the fastest growing source of demand for American ethane in recent years, rising to the largest single destination with 47% of exports last year.
Spain’s electricity-grid operator shrugged off concerns of another major blackout after detecting two sharp voltage variations in recent weeks. Red Electrica, which operates Spain’s grid, said that what The Wall Street Journal described as “recent voltage swings” didn’t threaten to knock out the grid because they stayed within acceptable limits. But the operator warned that variations could jeopardize the electricity supply if the grid didn’t overhaul its approach to managing a system that increasingly relies on intermittent, inverter-based generating sources such as solar panels. Red, which is 20% owned by the Spanish government, acknowledged that the high penetration of renewables was responsible for the recent fluctuations. Among the changes needed to improve the grid: real-time monitoring, which Heatmap’s Matthew Zeitlin noted in April “is necessary because traditionally, grid inertia is just thought of as an inherent quality of the system, not something that has to be actively ensured and bolstered.”
It’s not just Spain facing blackouts. New York City will have a power deficiency equivalent to the energy needed to power between 410,000 and 650,000 homes next summer — and that number could double by 2050, the state’s grid operator warned this week in its latest five-year report. “The grid is at a significant inflection point,” Zach Smith, senior vice president of system and resource planning for NYISO, said in a statement to Gothamist. “Depending on future demand growth and generator retirements, the system may need several thousand megawatts of new dispatchable generation within the next 10 years.”
Sodium-ion batteries are all the rage, as Heatmap’s Katie Brigham reported yesterday about the commercial breakthrough by the startup Alsym. But a major challenge facing sodium-ion batteries compared to lithium-ion rivals is the stability of the cathode material in air and water, which can degrade the battery’s performance and lifespan. A new study by researchers at Tokyo University of Science found that one ingredient can solve the problem: Calcium. By discovering the protective effects of calcium doping in the batteries, “this study could pave the way for the widespread adoption” of sodium-ion batteries.
Rob talks with the author and activist about his new book, We Survived the Night.
Julian Brave NoiseCat is a writer, Oscar-nominated filmmaker, champion powwow dancer, and student of Salish art and history. His first book, We Survived the Night, was released this week — it uses memoir, reporting, and literary anthology to tell the story of Native families across North America, including his own.
NoiseCat was previously an environmental and climate activist at groups including 350.org and Data for Progress. On this week’s episode of Shift Key, Rob talks with Julian about Native American nations and politics, the complexity and reality of Native life in 2025, and the “trickster” as a recurring political archetype.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is off this week.

Here is an excerpt from our conversation:
Robinson Meyer: What were lessons that you took away from the writing of the book, or from the reporting of the book, that changed how you thought about climate or the environment in some way that maybe wasn’t the case when you were working on these issues full time?
Julian Brave NoiseCat: I would say that while I was working on climate issues, I was actually, myself, really changing a lot in terms of my thoughts on how politics worked and did not work. I think I came into my period of my life as a climate activist really believing in the power of direct action, and protest, and, you know, if you get enough people in the streets and you get enough politicians on your side, you eventually can change the laws. And I think that there is some truth to that view.
But I think being in DC for four years, being really involved in this movement, conversation — however you want to put that — around the Green New Deal, around eventually a Biden administration and how that would be shaped around how they might go about actually taking on climate change for the first time in U.S. history in a significant way, really transformed my understanding of how change happens. I got a greater appreciation, for example, for the importance of persuading people to your view, particularly elites in decision-making positions. And I also started to understand a little bit more of the true gamesmanship of politics — that there is a bit of tricks and trickery, and all kinds of other things that are going on in our political system that are really fundamental to how it all works.
And I bring that last piece up because while I was writing the book, I was also thinking really purposefully about my own people’s narrative traditions, and how they get at transformations and how they happen in the world. And it just so happens that probably the most significant oral historical tradition of my own people is a story called a coyote story, which is about a trickster figure who makes change in the world through cunning and subterfuge and tricks, and also who gets tricked himself a fair amount.
And I think that in that worldview, I actually found a lot of resonance with my own observations on how political change happened when I was in Washington, D.C., and so that insight did really deeply shape the book.
