On environmental science, violent tornadoes, and more bad news for Tesla

Current conditions: Flash flooding in southern Spain forced evacuations • Tropical Storm Jude displaced thousands of people in Madagascar, Malawi, and Mozambique • Huge swathes of Texas, Oklahoma, Kansas, and Missouri are under red flag warnings today as strong winds bring another day of extreme fire weather to the region.
The Environmental Protection Agency reportedly plans to eliminate a department that conducts essential research and informs environmental policy. The Office of Research and Development is the agency’s largest department and has studied everything from fine particle pollution in the air to the health risks of fracking and forever chemicals. Its closure would cut up to 1,155 research jobs and “serve the Trump administration’s dual goals of reducing the size of government while potentially easing the regulation of the chemical and fossil fuel industries,” as The New York Times put it.
The move may also face legal hurdles. Rep. Zoe Lofgren of California, the top Democrat on the House science committee, said the office was created by congressional statute and cannot just be dissolved. She added that gutting the department would prevent the EPA from fulfilling its legal responsibilities to use cutting-edge science to shape policy. “Every decision EPA makes must be in furtherance of protecting human health and the environment, and that just can’t happen if you gut EPA science,” Lofgren said in a statement.
In other EPA news, the agency failed to meet a judge’s Monday deadline to provide clear and direct evidence of waste, fraud, or abuse by nonprofit groups approved for $20 billion in climate grants under the Inflation Reduction Act’s Greenhouse Gas Reduction Fund, which Administrator Lee Zeldin has been attempting to terminate. Instead, the agency pointed to “unidentified media reports” and an undercover video of an EPA staffer discussing the Biden administration’s rush to get federal grants out the door before the Trump administration took over. Zeldin first froze the funds and then canceled the loans entirely, prompting lawsuits from several of the grantees.
The Department of Energy yesterday released $57 million to Holtec to help restore and restart carbon-free power generation at the Palisades Nuclear Plant in Michigan, which shuttered in 2022. This is the second disbursement, following the January release of $38 million (the total loan guarantee is for up to $1.52 billion). The loan was approved during the Biden administration under the Inflation Reduction Act’s Energy Infrastructure Reinvestment program, though the Trump administration was quick to take credit. “Today’s action is yet another step toward advancing President Trump’s commitment to increase domestic energy production, bolster our security, and lower costs for the American people,” Energy Secretary Chris Wright said in a release that avoids any mention of the words “clean” or “carbon” or “emissions.” So long as Holtec can get the necessary permits, the Palisades facility will be the first commercial nuclear reactor in the U.S. to restart, and will “support or retain” 600 jobs and provide 800 megawatts of power in Michigan.
The deadly storm system that ripped across the South and Midwest over the weekend spawned at least two EF4 tornadoes in Arkansas, according to the National Weather Service. These are some of the most violent tornadoes, representing the second-highest level on the Enhanced Fujita scale used to rate tornado strength, with wind speeds from 166 to 200 miles per hour EF4s are also the rarest tornadoes, accounting for just 0.5% of all tornadoes in the U.S. between 2000 and 2022. Early damage surveys indicate one tornado ran for an hour, crossing 46 miles through two counties, with winds up to 170 miles per hour; another tornado had a path of 14.5 miles, a max width of one mile, and wind speeds reaching 190 miles per hour. Luckily no one seems to have been killed in these two twisters, though there were several injuries. But the larger tornado outbreak left at least 24 people dead and destroyed hundreds of homes across 12 states.
Trade tensions between Canada and the U.S. have prompted Toronto’s mayor to stop offering drivers financial incentives to buy Tesla vehicles for ride shares or taxis. “There are other electric cars they could purchase,” said Mayor Olivia Chow. “If you want to buy a Tesla, go ahead, but don’t count on taxpayer money to subsidize it.” She told Reuters the move was a direct response to Tesla CEO Elon Musk’s involvement with the Trump administration.
Meanwhile, insurance experts warn that an increase in acts of vandalism targeting Teslas may prompt insurers to hike rates for the vehicles. “Tesla owners better buckle up,” wrote Rob Stumpf at InsideEVs. “Things could get worse before they get better — at least while Musk lives a double-life as part-time CEO and part-time head of state.”
And finally, car listings data suggests prices for used Teslas are falling three times faster than the used car market overall. “So much for Tesla vehicles becoming ‘appreciating assets,’” wrote Fred Lambert at Electrek.
A German court will hear testimony this week in a longstanding climate lawsuit that could hold major greenhouse gas polluters financially responsible for their contributions to climate change. The case was filed in 2015 by a Peruvian farmer named Saúl Luciano Lliuya, who argues that German multinational energy giant RWE is partly to blame for rising flood risks in his village of Huaraz due to a melting glacier. He wants the company to pay for flood prevention measures. In 2022, court judges flew from Germany to the Peruvian Andes to observe the melting glacier and collect evidence for the case, “a global first for any climate case,” The Washington Post reported at the time. The report also noted that if the lawsuit succeeded, “major polluters anywhere may be liable for the increasingly disastrous consequences of greenhouse gas emissions.”
A new study finds that beef from grass-fed cattle does not have a lower carbon footprint than beef from cattle fed grains and corn. “I have a hard time imagining … a situation in which it will prove environmentally, genuinely wise, genuinely beneficial, to raise beef,” said study author Gidon Eshel, a research professor of environmental physics at Bard College.

The data center boom is everywhere you look in U.S. economic and emissions data.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
It isn’t exactly a new thought, but I’ve been struck recently by how many trends in America’s economic and environmental data are fundamentally about the data center boom and the return of electricity demand:
First, the Energy Information Administration reported this week that U.S. emissions grew by more than 2% last year, driven by surging electricity demand and an increase in coal-fired generation. What caused that higher power demand? New factories and data centers — as well as record summertime cooling demand.
Second, many of the new factories driving that higher power demand are themselves producing goods that are … let’s say … data center-adjacent. There are the enormous new semiconductor fabs, of course. But Ford and General Motors have also set up new production lines (or repurposed old ones) to manufacture grid-scale batteries to meet power demand.
Third, take a look at the recent U.S. spending on private non-residential construction — in other words, everything American companies are building that is not houses, condos, or apartments.
The construction industry’s spent almost $60 billion on data centers over the past year, which is more than it spent on all other office buildings combined (and more than it spent building warehouses, too). Just a handful of categories — data centers, power plants, electricity infrastructure, and certain kinds of electronics manufacturing — now make up a third of all U.S. private non-residential construction investment. They’ve never made up such a large share of construction spending since data collection began in 2014.
As The New York Times recently noted, the American economy is unusually dependent on the American stock market right now — and the stock market is unusually dependent on artificial intelligence. This week, investors started to balk at the enormous spending hyperscalers are planning to keep building out the AI boom; Alphabet’s shares dropped 8% this week after it boosted its planned 2026 capital expenditure and signaled 2027 will be even bigger. If the data center boom started to slow down in earnest, then more than just that budget will change.
Speaking of which, my colleague Emily Pontecorvo wrote earlier this week about how many businesses are struggling to even estimate their carbon emissions from artificial intelligence. The carbon accounting startup Watershed recently unveiled a new formula to help companies get a sense of their AI-related emissions.
But even that formula is still limited by the amount of data hyperscalers publish — and they don’t publish that much. Google, for instance, is the only AI company that has (laudably) provided estimates of its emissions on a per-prompt basis. Yet no company has published its per-token emissions, or how emissions sync up with particular models or regions.
So Emily asked Google: Why aren’t you — or any other model provider — disclosing this kind of data yet?
The tech company didn’t get back to us until after we’d published Emily’s story. But its response was interesting enough that I wanted to quote some of it here.
The problem is “industry consensus,” Cooper Elsworth, a Google spokesperson, told us. “There is currently very little consensus on how to comprehensively and fairly measure the serving environmental impact of generative AI (such as text generation),” he wrote. “Without standardized, ‘apples-to-apples’ frameworks, it is difficult to compare different providers accurately.”
That’s partly because energy use — and emissions data — can vary from site to site and depend on “custom-built hardware, software compilers, and advanced inference techniques.” And he claimed Google doesn’t always have the measurement hardware in place to provide such specific estimates: “Providing precise, repeatable data requires highly advanced measurement infrastructure,” he said. “For example, software-based energy monitoring tools often suffer from sampling biases. For our study, we had to step away from top-down averages and directly measure actual energy at the physical power supply unit (PSU) level across our deployed fleet. Not all providers have the telemetry or data sets required to benchmark their operations at this level of granularity.”
Read Emily’s story to understand the other reasons why estimating — or even “guesstimating” — AI-related carbon emissions is so challenging.
A conversation with Emma Uridge of the Kansas Health Institute.
This week’s conversation is with Emma Uridge, analyst with the Kansas Health Institute. Uridge spent copious hours analyzing state and local laws on data center development to best understand how policymakers are responding to the potential environmental public health impacts of large AI infrastructure, including power and water. The report, which came out this week, also goes in depth into those health impacts. I reached out to her to discuss what she sees as must-watch territory for our readers on this emerging policy arena.
Our conversation was lightly edited for clarity.
What is actually being done on policy when it comes to data centers — beyond moratoria of course?
So first I’d like to just talk about the point of moratoria. It’s helpful to talk about how these policies emerge in the first place. One area where moratoria are helpful is when a data center is proposed but the county has no approach for how they’d like to potentially regulate them. That’s temporary, most of the time. It lets local governments conduct research on the various impacts and also negotiate community benefits, ones that can mitigate any potential negative impacts — like Lancaster Pennsylvania, which instituted a community benefit agreement that maximized the potential benefits of development while mitigating what large data centers can do. That agreement looked at capping municipal water use at 20,000 gallons per day and requiring 100% clean energy. It had financial penalties for non-compliance. The company also committed $20 million to their local economic development and clean energy fund. There are ways to negotiate with developers.
We also see amendments to existing zoning. Data center proposals are increasingly popping up in rural areas, many of which are unzoned, so there’s no way a county can negotiate unless there’s a moratorium in place.
Other policy solutions include different performance standards or requiring on-site renewable energy, like what Jefferson County, Missouri, looked at. Also setback requirements, mandatory noise buffers, ending by-right zoning.
Where are local governments getting ideas for regulating data centers?
A lot of the technical information comes from developers. That can in cases be seen as a biased source of information. I wouldn’t say there’s a dedicated group providing assistance to local governments when a project is proposed — which is a similar story to wind industry development, where we have only a handful of consultants who provide technical advice. It can be really helpful to get a multi-disciplinary approach to hearing information. It can be helpful to have the utility commission, public health folks, those in academia, as well as the developer.
As of right now, especially in rural areas, local governments have a hard task of balancing pushback while getting the most accurate, evidence-based, neutral information to make decisions. That balance can be contentious.
What is the federal government doing on data center policy? How is the Trump administration approaching it?
A few things there. In the early days, the drive was for AI expansion and to be competitive with foreign adversaries. Now due to the amount of public pushback in red and blue localities and a more cautious approach.
I’m not seeing a lot of actual policy movement at this time.
I know the EPA is looking at the chemicals used in cooling data centers because when that water is cycled through the system, some of it is discharged into the water system, so they’re looking at the Toxic Substances and Control Act for monitoring that.
How much of an impact does this minimal federal role have on industry behavior?
Y’know, this isn’t specific to data centers. This is true for all kinds of large-scale development: there’s a need to require some sort of federal monitoring and regulation.
That’s where I see an emerging role for public health. At the federal level, there could be policy movement towards requiring some sort of environmental monitoring at data centers to make sure they’re operating responsibility. Looking at specific water use relative to water availability and what happens when there’s a time of severe, persistent drought. With air quality too — we’ve seen areas where the grid isn’t as reliable so their diesel generators are kicking on more and affecting air quality for residents.
We’re just not seeing all of that right now. We need corporate disclosure.
What do you see as the most important public health impacts from data center development?
It varies by localities. The most discussed obviously is water usage. One thing I’d note about my conversations with folks enthusiastic around emerging tech is, there are still questions that need to be asked about the capacity of localities to support a data center. Like a small town in Kansas may only be using 40% of their water for their utility needs. If a data center came online, how much of that water goes to the data center?
One area underexplored within the public health discipline is energy poverty and energy security. The ability of a household to meet the needs of everything energy provides in our lives. It’s known we have an aging electric grid but we’re not talking enough about large-scale blackouts when the grid is not sufficient to support some of these new data centers.
Plus more of the week’s big development fights.
1. Laramie County, Wyoming — Meta is fighting the fine it received in the Cheyenne data center water pollution controversy, and the conflict between the tech giant and the city’s small board of public utilities is continuing to spill out into the public.
2. Niagara County, New York — This county just rejected a solar project’s highway work permits in a show of retaliation against the state’s Office of Renewable Energy Siting.
3. Barron County, Wisconsin — The anti-solar protest is the new campaign stop in deep red Wisconsin.
4. Chesapeake, Virginia — A large battery storage project on the Virginia coastline is on the rocks amidst rampant local opposition.
5. Lewis County, West Virginia — West Virginia is now a key battleground in the fight over transmission, as a line spanning all of West Virginia and Maryland — and cutting through Data Center Alley in Virginia — causes compounding consternation.
