Climate change was a major topic.
If we learned anything new from the first Republican presidential debate in Milwaukee on Wednesday night, it was not what anyone planned to do about climate change. The candidates failed to expand on their already scant or nonexistent platforms. Almost all of them failed to acknowledge that climate change was caused by humans.
But what was notable was the fact that the issue has finally earned a more prominent spot on the debate stage. Four years ago, activists railed against Democratic primary debate moderators for not asking any questions about climate change until the second hour of the program. The Fox News hosts got to the issue in about 20 minutes.
Below we’ve recapped what happened next, and the other most remarkable moments of the night for global warming, decarbonization, and energy.

North Dakota Governor Doug Burgum, making his first comments in the debate, used a prompt to discuss the economy as a chance to rail against President Biden's historic climate law, the Inflation Reduction Act.
“The economy, energy, and national security are all tied together. We’ve got a plan, the $1.2 trillion of Green New Deal spending in the ‘Inflation Creation Act,’ that’s subsidizing China,” Burgum said. His primarily claim: That IRA subsidies will benefit Chinese battery and renewable manufacturers.
“If we’re going to stop buying oil from the Middle East and start buying batteries from China, we’re going to trade OPEC for Sinopec.”

It only took 20 minutes for the Republican debate’s big climate change question to be asked.
Moderator Bret Baier chronicled the summer’s disasters, mentioning missing people in Maui, the rarity of a tropical storm in California, and the overheated ocean in Florida. Then Fox News played a clip from a young conservative.
Alexander Diaz, a student at the Catholic University of America on behalf of the conservative group Young America’s Foundation, noted the importance of climate change to young voters, teeing up Fox News’ Martha MacCallum to ask a simple question: “We want to start on this with a show of hands. Do you believe … human behavior is causing climate change? Raise your hand if you do.”

Vivek Ramaswamy initially introduced himself to the American people on Wednesday night as a “skinny guy with a funny last name” — but perhaps his name was more aptly made, at least with many young conservatives, by calling “the climate change agenda … a hoax.”
Ramaswamy, a biotech entrepreneur running for his first political office, has previously claimed he’s not a “climate denier,” but also played coy, saying global warming will not be “entirely bad.” It was also not the first time he’s attacked what he calls “the climate cult in America.” In a video shared by his Twitter account this spring, Ramaswamy slammed climate activists for allegedly saying “that you have to abandon carbon emissions at all costs if you live in the United States.” He added, “It’s a cult that says … ‘We’re against nuclear energy’ … because nuclear energy might be too good at solving the alleged clean energy problem, which means they couldn’t use the climate as an excuse to advance a very different agenda.” Nuclear energy has historically been something of a bogeyman for environmentalists, who fear waste and meltdowns, but the nuclear power industry is also receiving billions of dollars from Biden’s two biggest pieces of legislation, the Inflation Reduction Act and the Bipartisan Infrastructure Law.
Wednesday’s “hoax” comment specifically came in reaction to the Fox News moderators trying to push the candidates into a yes-or-no answer about whether humans are responsible for climate change. Notably, no one immediately raised their hand. An overwhelming consensus of scientists — 99.9% of them, The Guardian found — say climate change is caused by mankind.
Ramaswamy’s answer was clearly an attempt to align his candidacy with former President Trump, who has called climate change "a hoax," “a total hoax,” “an expensive hoax,” and “a total, and very expensive, hoax.” Somewhat surprisingly, Ramaswamy's quip was met by audience boos — as well as interruptions from other candidates, who took issue with him calling himself the “only person on the stage who wasn’t bought and paid for.”
Earlier in the debate, a number of candidates had tip-toed around the possibility of “open[ing] up … energy production,” though Ramaswamy — who’s been said to be gunning to be “Republicans’ next Trump” — was characteristically blunt on that point, as well. “This isn’t that complicated, guys,” the 38-year-old chided his peers. “Unlock American energy. Drill. Frack. Burn coal. Embrace nuclear.” —Jeva Lange

When moderator Martha MacCallum asked the candidates to raise their hand if they believe that human behavior is causing climate change, Florida Governor Ron DeSantis took issue with the question.
“We’re not schoolchildren,” DeSantis immediately snapped back before anyone had put a hand in the air. “Let’s have the debate.” But instead of having the debate, he pivoted to bashing President Biden and showing off his extreme weather bonafides. “Biden was on the beach while those people were suffering,” he said, referencing the president’s response to the wildfires in Maui. “As someone who’s handled disasters in Florida, you gotta be activated.”
From there, the moment descended into chaos. Vivek Ramaswamy interrupted to say the “climate change agenda” was a “hoax.” Christie jumped in to toss insults at Ramaswamy.
The only candidate who managed to get a word in about their stance on the issue was Nikki Haley. ”We care about clean air and clean water but there’s a right way to do it,“ she said. “First of all, is climate change real? Yes it is.”
Haley's sole proposal was to push China and India to cut their emissions. She accused Biden of putting money in China’s pocket by subsidizing electric vehicles, and said the subsidies are “not working.” However, car makers have responded to the Inflation Reduction Act’s subsidies by investing millions in domestic manufacturing and domestic supply chains.
At the end, President Biden chimed in on Twitter with the last word. —Emily Pontecorvo

Some of the Loan Programs Office’s signature programs are hollowed-out shells.
With a stroke of President Trump’s Sharpie, the One Big Beautiful Bill Act is now law, stripping the Department of Energy’s Loan Programs Office of much of its lending power. The law rescinds unobligated credit subsidies for a number of the office’s key programs, including portions of the $3.6 billion allocated to the Loan Guarantee Program, $5 billion for the Energy Infrastructure Reinvestment Program, $3 billion for the Advanced Technology Vehicle Manufacturing Program, and $75 million for the Tribal Energy Loan Guarantee Program.
Just three years ago, the Inflation Reduction Act supercharged LPO, originally established in 2005 to help stand up innovative new clean energy technologies that weren’t yet considered bankable for the private sector, expanding its lending authority to roughly $400 billion. While OBBBA leaves much of the office’s theoretical lending authority intact, eliminating credit subsidies means that it no longer really has the tools to make use of those dollars.
Credit subsidies represent the expected cost to the government of providing a loan or a loan guarantee — including the possibility of a default — and thus how much money Congress must set aside to cover these potential losses. So by axing these subsidies, Congress is effectively limiting the amount of lending that the LPO can undertake, given that many third-party lenders would be reluctant to finance riskier, more novel, or larger projects in the absence of federal credit support.
“The LPO is statutorily allowed to take loans on its books to finance these projects in these categories, but it has no credit subsidy by which to take the risk required to do so,” Advait Arun, senior associate of energy finance at the Center for Public Enterprise and a Heatmap contributor, told me.
The particular programs that have been eliminated support new and improved energy technologies, clean energy infrastructure, fuel efficient vehicles, and help native communities access energy project financing. The long-running Loan Guarantee Program and the advanced vehicles program in particular are behind some of the best known LPO efforts, supporting companies such as Tesla, Ford, and NextEra Energy, and projects such as Georgia’s Vogtle nuclear reactors, the Thacker Pass lithium mine, and Shepherd’s Flat, one of the world’s largest wind farms.
The Loan Guarantees Program is “the big Kahuna,” Arun told me. “This is the longest-standing program of the LPO. So to see this defunded is like, you’re decapitating the LPO’s crown jewel.”
The program only has about $11 million left over in credit subsidies, consisting of funding that it received prior to the IRA’s appropriations. That won’t be enough to make any meaningful loans, Arun said, and is more likely to be used to “keep a skeleton crew online” for any remaining administrative tasks.
Then there’s the Energy Infrastructure Reinvestment Program, which the IRA stood up with a whopping $250 billion in lending authority to transition and transform existing fossil fuel infrastructure for clean energy purposes. Now, OBBBA has axed the program’s remaining $5 billion in credit subsidies and replaced it with $1 billion in new subsidies for projects that “retool, repower, repurpose, or replace” existing energy infrastructure, with a focus on expanding capacity and output as opposed to decarbonizing the economy. It also refashioned the program as the predictably-named “Energy Dominance Financing” initiative.
The new-old program — which the law extended through 2028 — no longer requires LPO-funded infrastructure to reduce or sequester emissions, broadening the office’s lending authority to include support for fossil fuel and critical minerals projects. It also adds language encouraging the LPO to “support or enable the provision of known or forecastable electric supply,” which Arun fears is a “backend way of penalizing the addition of renewable energy” on previously developed land.
“Under the Trump administration’s direction, [the LPO] can use that term, ‘known and forecastable,’ to actually just say, well, guess what? Renewables are not known or forecastable because they are intermittent due to the weather,” Arun told me. So while government and private industry were once excited about, say, turning sites originally developed for coal mining or coal ash disposal into solar and battery facilities, those days are probably over.
Carbon capture in particular stands to suffer from this reprogramming, Arun said, explaining that while the Biden LPO saw potential in adding carbon capture to natural gas and coal plants, its current incarnation will no longer allocate funding in any meaningful amount “because reducing emissions is no longer part of the LPO’s mandate.” Some policymakers and clean energy developers had also hoped that excess renewable energy would make it economically feasible to power the production of hydrogen fuel with renewable energy. But with this law — and really each passing day under Trump — a mass buildout of solar and wind seems less and less likely, making it doubtful that green hydrogen will move down the cost curve.
As bleak as this looks, it’s better than it could have been. There was no guarantee that Trump would keep the LPO around at all. Even in this denuded state, the office can still fund the expansion of existing nuclear projects, and perhaps even the buildout of transmission lines or battery projects on brownfield sites, Arun said, depending on how LPO’s leadership ends up interpreting what it means to “increase the capacity output of operating infrastructure.”
But in many ways, what happened with the LPO looks like another instance of the Trump administration picking winners and losers: Yes to clean, firm energy and fossil fuels, no to solar, wind, and electric vehicles.
Take the Advanced Technology Vehicle Manufacturing Program, for example. OBBBA nixed both its credit subsidies and its tens of billions of dollars in lending authority. That’s hardly a surprise, given that the Bush administration created the program in 2007 explicitly to support the domestic development and manufacture of fuel-efficient vehicles and components. But it means that unlike the LPO programs for which lending authority still stands, even if Congress wanted to, it could not redesign the advanced vehicles program to serve a more Trump-aligned purpose. Safer, I suppose, to cut off any opening for funding EVs and hybrids.
The latest LPO rescissions add to the growing list of reasons the private sector has to be wary of the consistently inconsistent landscape for federal funding, Arun told me. He worries that slashing the LPO’s authority at the same time as there’s so much uncertainty around tax credit eligibility will lead some companies to forgo federal funding opportunities altogether.
“We’ll see if private developers even want to play around with the LPO,” Arun told me, “given the uncertainty around the rest of the federal landscape here.”
Electric vehicle batteries are more efficient at lower speeds — which, with electricity prices rising, could make us finally slow down.
The contours of a 30-year-old TV commercial linger in my head. The spot, whose production value matched that of local access programming, aired on the Armed Forces Network in the 1990s when the Air Force had stationed my father overseas. In the lo-fi video, two identical military green vehicles are given the same amount of fuel and the same course to drive. The truck traveling 10 miles per hour faster takes the lead, then sputters to a stop when it runs out of gas. The slower one eventually zips by, a mechanical tortoise triumphant over the hare. The message was clear: slow down and save energy.
That a car uses a lot more energy to go fast is nothing new. Anyone who remembers the 55 miles per hour national speed limit of the 1970s and 80s put in place to counter oil shortages knows this logic all too well. But in the time of electric vehicles, when driving too fast slashes a car’s range and burns through increasingly expensive electricity, the speed penalty is front and center again. And maybe that’s not a bad thing.
You certainly can notice the cost of lead-footedness in a gasoline-powered car. It’s simpler today, when lots of vehicles have digital displays that show the miles per gallon you’re getting, than in the old days when you had to do the math yourself. An EV puts the hard efficiency math right in front of you. Battery life is often displayed in terms of estimated miles of range remaining, and those miles evaporate before your eyes if you climb a mountain or accelerate like a drag racer.
This is no academic concern, like trying to boost one’s fuel efficiency through hypermiling techniques such as gentle acceleration, downhill coasting, and killing the AC. In six years of owning a Tesla Model 3, I’ve pushed its range limits trying to reach far-flung national parks and other destinations where fast chargers are scarce. I’ve found myself in numerous situations where I’ve set the cruise control at exactly the speed limit or slightly below to make sure the car would reach the one and only charging depot in the vicinity. For particularly close calls, I’ve puttered white-knuckled with one eye on Tesla’s in-car energy app — and felt my stomach drop when I found myself underperforming its expectations.
Fortunately, slow works. Three years ago I managed a comfortable round-trip from what was then the closest Tesla Supercharger to Crater Lake National Park by driving there down a 55-mile-per-hour two-lane highway; at freeway speed, my little battery probably wouldn’t have made it. Today, my fully charged Model 3 might make it something like 130 to 140 miles at interstate speed, depending on elevation. Go a little slower and it comes close to matching the 200 miles of supposed range.
Fear is the speed-killer, sure. The chance of being stranded with a dead battery is enough for any driver to be scared straight into observing the posted limit. But having all that data at the ready had already started to affect my driving habits even when there was no danger of stranding myself. It’s hard to watch the range drop when you slam the accelerator without thinking of the Interstellar meme about how much this little maneuver is going to cost us. With the price of electricity at the fast charger rising, I’m much more conscious of wasting a few kilowatt-hours by being in a hurry.
The difference is stunningly clear in the kind of controlled range tests that car sites and EV influencers have been conducting. For example, the State of Charge YouTube channel recently drove the Cadillac Escalade IQ, the fully electric version of the status SUV that is officially rated at 465 miles of range. Driven at exactly 70 miles per hour until it ran out of juice, the big EV exceeded that estimate by traveling 481 miles. With the speedometer held at 60 miles per hour, however, the vehicle went 607 miles — more than 100 miles more.
Granted, the Caddy’s comically large 205 kilowatt-hour battery — more than three times as big as the one in my little Tesla — does the lion’s share of the work in allowing it to go so very many miles. A peek into State of Charge’s data, though, makes it clear what 10 miles per hour can do. Dropping from 70 miles per hour to 60 caused the car’s miles per kilowatt-hour figure to rise from 2.1 to 2.6 or 2.7.
That’s not to say EV ownership turns every driver into an energy-obsessed hypermiler. One blessing of the huge batteries that go into Cadillac EVs and Rivians is freeing their drivers from some of the mental burden of range calculations. With driving ranges reaching well above 300 miles, you’re going to make it to the next plug even if you drive like a maniac.
Even so, the increased awareness of the cost of electricity might make some of us reconsider the casual speeding we all do just to take a few minutes off the trip. That’s a good thing for public safety: Big EV batteries make these vehicles heavier than other cars, on average, and thus potentially more dangerous in auto accidents. And slowing down will be especially relevant as electricity prices outpace inflation. Consumer electricity prices are up nearly 5% over last year and are poised to get worse: The budget reconciliation bill signed by President Trump last week won’t help, as one projection sees it leading to an increase in annual energy bills of up to $290 by 2035.
To be honest, the biggest problem of slowing down a little isn’t really the extra time it takes to get someplace. It’s trying to conserve in a world where 5 to 10 miles per hour over the speed limit is the expectation. I once had to cross 140 miles of wind-swept New Mexico expanse from Albuquerque to Gallup on a single charge, a task that required driving 55 miles per hour in a 65 zone of the interstate, holding on tight as semi trucks flew past me in revved aggravation. We made it. But if you really want to make your electrons go farther, then be prepared to become the target of road rage by the hasty and the aggrieved.
On federal layoffs, copper tariffs, and Texas flood costs
Current conditions: Three people were killed in southern New Mexico after heavy rains on Tuesday caused flooding • Parts of the western Mediterranean Sea are 12.6 degrees Fahrenheit warmer than average • Search operations are underway for 30 people missing in India’s Himachal Pradesh state following flash floods and landslides.
The Supreme Court on Tuesday lifted a lower court ruling that had blocked mass layoffs of federal workers, clearing the way for a significant reduction in the civil service. Justice Ketanji Brown Jackson was the only dissenting vote, writing that the court had a “demonstrated enthusiasm for greenlighting this President’s legally dubious actions in an emergency posture.” Technically, SCOTUS’ ruling is only temporary, and the case could eventually return for the court to consider at a later date, with Justice Sonia Sotomayor noting, “The plans themselves are not before this Court, at this stage, and we thus have no occasion to consider whether they can and will be carried out consistent with the constraints of law.” But “in practice,” the court’s move allows President Trump to “pursue his restructuring plans, even if judges later determine that they exceed presidential power,” The New York Times writes.
The Trump administration has signaled its intention to reduce the workforce by 107,000 employees in the next fiscal year. It plans the steepest cuts for the Department of Education, the Office of Personnel Management, and the General Services Administration, but roles at the National Aeronautics and Space Administration, National Science Foundation, and Department of Energy are also up for reductions. As I’ve previously written, such cuts to the civil service will long outlast President Trump. “It will be very difficult, if not impossible, to restore the kind of institutional knowledge that’s being lost,” Jacqueline Simon, policy director of the American Federation of Government Employees, the largest union of federal government workers, told me.
President Trump announced on Tuesday that he intends to impose a 50% tariff on copper, a move that follows earlier tariffs on steel and aluminum. The process for imposing those tariffs, my colleague Matthew Zeitlin notes, involves recognizing that the product being tariffed is “essential to national security, and thus that the United States should be able to supply it on its own.” But while a steep new tariff could incentivize increased copper mining in the United States, such mines can take years to open, and copper must be smelted and refined before it can be used — an industry that is currently at capacity in the U.S. and dominated by China. Nevertheless, copper is crucial for “a broad array of electrical technologies, including transmission lines, batteries, and electric motors,” Matthew writes. “Electric vehicles contain around 180 pounds of copper on average.”

The death toll in the Texas floods rose to over 100 on Tuesday, with Governor Greg Abbott telling reporters that another 161 people remain unaccounted for in Kerr County. Already one of the deadliest floods in modern U.S. history, the disaster is also set to be one of the costliest, with AccuWeather estimating total damage and economic loss between $18 billion and $22 billion. “The damage, impacts on future tourism, cost of search and recovery efforts, extensive cleanup that will be needed, as well as insurance claims after this catastrophic flash flood, will have long-lasting economic impacts in the Hill Country region of Texas,” AccuWeather Chief Meteorologist Jonathan Porter said in a statement.
As I wrote on Tuesday, the Texas floods were a disaster despite the forecasting, not because of it. While some global weather models underestimated the storm, NOAA’s cutting-edge specialized models “got this right,” UCLA and UC Agriculture and Natural Resources climate scientist Daniel Swain told me. Funding for those models — as well as research into severe thunderstorms and rainstorms like the one in Texas — is set to be zeroed out in the Trump administration’s 2026 budget.
The Department of Energy has hired three scientists who are among the minority of experts to doubt or downplay the impacts of human activity on global warming, The New York Times has learned. The scientists include physicist Steven E. Koonin, the author of the bestselling book Unsettled: What Climate Science Tells Us, What it Doesn’t and Why it Matters, which has been criticized for “not [comporting] with the evidence”; meteorologist Roy Spencer, the author of The Great Global Warming Blunder: How Mother Nature Fooled the World’s Top Climate Scientists, which alleges IPCC researchers made a “mix-up between cause and effect when analyzing cloud and temperature variations”; and atmospheric scientist John Christy, who’s been accused of using misleading graphs to downplay the extent of human activity on climate change. The New York Times was unable to immediately learn “what the three scientists were working on or whether they were being paid,” but the hires come at a time when the federal government is also laying off long-tenured climate and atmospheric scientists as well as removing mentions of climate change from government websites.
China is constructing nearly three-quarters of all solar and wind power projects being built globally, according to a new report by the Global Energy Monitor. Of about 689 gigawatts currently under construction worldwide, 510 gigawatts of utility-scale solar and wind were within China’s borders, the report found. Additionally, China accounts for 29% of all planned wind and solar projects worldwide, followed closest by Brazil, at just over 9%.
China’s wind and solar capacity surpassed its coal and gas capacity for the first time during the first quarter of 2025, supplying 23% of the country’s electricity consumption, the report adds. Even offshore wind, a “small portion of China’s overall renewable capacity,” now contributes over 50% of the overall offshore wind capacity in construction worldwide.

Cemeteries are “a mosaic of different habitats. This means that species from forests, hedgerows, grasslands, and even fields can find substitute habitats there.” —Ingo Kowarik, an urban ecologist and retired professor at the Technische Universität Berlin, on the burgeoning field of cemetery biodiversity.
