On GM eating the tariffs, California’s utility bills, and open-sourcing climate models

Current conditions: U.S. government forecasters are projecting hurricane season to ramp up in the coming weeks, with as many as nine tropical storms forming in the Caribbean by November • Southern Arizona is facing temperatures of up to 114 degrees Fahrenheit • Northeast India is experiencing extremely heavy rainfall of more than 8 inches in 24 hours.
Secretary of Energy Chris Wright said his agency is preparing to rewrite previously published National Climate Assessments, which have already been removed from government websites. In an interview with CNN’s Kaitlan Collins, Wright said the analyses “weren’t fair in broad-based assessments of climate change.” He added: “We’re reviewing them, and we will come out with updated reports on those and with comments on those reports.”
The former chief executive of the fracking company Liberty Energy, Wright once eschewed the outright rejection of climate science that other Trump administration officials espouse. But as the Environmental Protection Agency works to withdraw the legal finding that gave the federal government the right to regulate planet-heating emissions under the Clean Air Act, Wright has ratcheted up his rhetoric. Earlier this week, he claimed that “ceaseless repeating from the media, politicians and activists claiming that climate change is making weather more dangerous and severe is just nonsense.” In response, my colleague Robinson Meyer noted on X: “This is a new and big turn from Secretary Wright. I’ve been pretty careful to never call him a climate change denier because while his claims about the science have been incredibly opinionated, I could see the ‘true’ thing he was trying to say. But this is just brazenly wrong.”
Days after the Department of the Interior revoked a designation opening millions of acres off the United States’ shores to offshore wind, the agency on Thursday launched “a full review of offshore wind energy regulations to ensure alignment” with “America’s energy priorities under President Donald J. Trump.” The review aims to examine “financial assurance requirements and decommissioning cost estimates for offshore wind projects, to ensure federal regulations do not provide preferential treatment to unreliable, foreign-controlled energy sources over dependable, American-made energy,” according to the press release announcing the move.
This is just the latest in a series of actions the administration has taken targeting renewables, particularly wind. For more on Trump’s all-out war against America's biggest source of non-emitting energy, here’s my colleague Jael Holzman.

General Motors is preparing to import batteries from Chinese giant CATL despite steep tariffs imposed by Trump. The automaker is buying the batteries to power the second-generation Chevrolet Bolt electric vehicle, in what The Wall Street Journal described as “a supply-chain Band-Aid for a company that touts extensive investments in U.S. battery manufacturing.”
The imports are meant to hold GM over for two years until the Detroit giant and its Korean partner LG Energy Solution can complete work on U.S. manufacturing sites to provide a domestic source of lower-cost batteries, according to Journal reporter Christopher Otts. GM’s EV sales surged in July following the introduction of the electric version of the popular Chevrolet Equinox SUV, in one of the brightest spots for the American EV market this summer.
California lawmakers are proposing a radical solution to curb rising electricity rates. Bills moving through the state’s legislature would use money raised from state bonds to help pay for the hugely expensive process of expanding the power grid and upgrading its equipment to better withstand wildfires, Canary Media’s Jeff St. John reported. The legislation would force the state’s big three utilities to accept public financing for a portion of the tens of billions of dollars they plan to spend on the power lines. The proposals come as steep rate hikes across the country become a political hot button ahead of next year’s midterm elections. As Robinson put it, “when you look across the power system, virtually every trend is setting us up for electricity price spikes.”
The sustainability data company Watershed announced a new partnership this morning with the Stanford Sustainable Solutions Lab to preserve the EPA’s model for carbon accounting. Dubbed “Cornerstone,” the project “will be a hub for open access” to software designed to assess Scope 3 emissions, the planet-heating pollution that comes from indirect downstream activities in a supply chain. “By combining the most trusted environmental data models and keeping them open to the world, we hope to help companies and organizations build and maintain momentum on sustainability,” Watershed’s co-founder Christian Anderson said in a statement. Wesley Ingwersen, the former EPA lead and architect behind the federal model, will serve as the initiative’s technical director.
The British government’s decision in May to hand back sovereignty over the Chagos Island to Mauritius more than two centuries after seizing the Indian Ocean archipelago and forcing out its residents to make way for a military base created a political uproar in the United Kingdom earlier this year. But British rule over the island chain yielded at least one major benefit beyond military defense. A new study found that the supersized Marine Protected Area the U.K. established in 2010 protected large ocean animals throughout much of their lifecycle. Scientists tracked sea turtles, manta rays and seabirds in the nearly 250,000-square-mile sanctuary. In total, 95% of tracking locations showed the area “is large enough to protect these wandering animals” which travel far to forage, breed and migrate. By contrast, the study from Exeter and Heriot-Watt universities found that seabirds in marine areas with smaller than 40,000 square miles “would be less well protected.”

France’s deadliest heat wave since 2003 killed more than 2,700 people — and possibly as many as 5,700.
More than 5,700 excess deaths were recorded in France during this summer’s record-breaking heat wave, the country’s health agency announced today. That makes the event — which ran, by the official reckoning, from June 17 to July 2 — the country’s deadliest heat wave in more than 20 years.
That’s in line with other estimates we’ve heard. EuroMOMO, a network of European public health agencies that track excess mortality, found that the continent saw more than 10,000 excess deaths during the same period. Roughly 90% of those victims were older than 65, it said. (France’s cohort seems similar: Adults older than 75 made up about two-thirds of the victims, the government said.)
These numbers are staggering — and much larger than some astute Heatmap readers might anticipate. If you read my colleague Jeva Lange’s piece on why it’s so hard to estimate heat deaths last week, she cited a much smaller estimate: Roughly 2,700 died in France during the most recent heat wave. That tally came from Christopher Callahan, an Indiana University scientist who studies climate change’s economic and social costs.
Why is there such a gap between the figures? I emailed Callahan to find out. He shared a few thoughts. First, he uses a different (and theoretically more rigorous) method than the French government: “Our approach uses a statistical relationship between temperature and mortality to explicitly quantify how many additional deaths are associated with a given day’s temperature,” he wrote. “France’s report of excess deaths is just based on how many more people died in late June compared to previous Junes - but we don’t know if those people died because of the heat or some other factor.” (Carbon Brief recently published a Q&A on these varying approaches.)
That might mean his estimate is right, in which case France has misidentified roughly nearly 3,000 deaths. But it could also mean his model, which is trained on data from 2004 to 2019, is “missing something,” he said, like a post-Covid change to public health risk. Last year, Callahan and his colleagues used a similar model to estimate deaths from France’s worst-ever heatwave, a 2003 episode that overwhelmed morgues and killed about 16,000 people. Even 23 years ago, global warming helped make that disaster larger than it needed to be: Some 6,000 of those deaths were due to climate change, their paper found.
Either estimate of the 2026 heat wave, of course, is shattering. As Jeva wrote, even the lower figure would mean the 2026 heat wave killed as many people as died in three years of French homicides. But the divergence in estimates tells us something else too: Even as climate change breaks records and alters our world, we’re never going to quite agree on where it ends and normal randomness begins.
The AI data center boom does not seem close to ending. Google’s parent company, Alphabet, announced its second quarter results this evening, and it beat Wall Street’s expectations, nearly quadrupling its profit on a year-over-year basis. Among the drivers: Its cloud business grew 82% compared to the same quarter last year. (As I’ve written, that rapid growth is helping to turn Alphabet and other hyperscalers into light industrial firms.)
The company’s AI bets seem to be paying off so far — so Google is now planning on spending even more on data centers, energy infrastructure and AI development this year than it once anticipated. It raised its estimates of 2026 capital expenditure to $195 billion to $205 billion, which is above earlier projections and twice as much as it spent in the same category last year. 2027 could be even bigger, it signaled. The company’s shares fell slightly on the news in after-hours trading, but from an energy and climate wonk perspective, the message is clear: For now, the AI demand surge transforming the power sector — and the real economy — continues to chug along.
