It’s official: Minnesota Governor Tim Walz got the rose.
On Tuesday morning, after days of frenzied speculation that floated names including Governor Josh Shapiro of Pennsylvania, Arizona Senator Mark Kelly, and Governor Andy Beshear of Kentucky, Kamala Harris announced that Walz’s name will be the one to underline hers on the presumptive Democratic presidential ticket.
Many on the climate left will likely be thrilled by the pick: Of all the finalists reportedly in contention for VP, Walz had the most impressive clean energy and environmental accomplishments. An Army veteran and former congressman of a rural, otherwise conservative Minnesota district, Walz has a record of working across party lines to get things accomplished. In 2009, he memorably voted for the doomed cap-and-trade bill and defended his position to tough crowds of Midwestern farmers and ranchers.
Within months of being sworn in as Governor of Minnesota in 2019, Walz set a goal for his state to get its electricity from 100% carbon-free sources by 2050. At the time, only a few other states had similar goals. “Climate change is an existential threat. We must take immediate action,” Walz argued at the time. “If Washington is not going to lead, Minnesota will lead.”
By the time Walz signed actual emissions legislation into law last year, he’d set an even more ambitious timeline — carbon-free electricity by 2040. The bill also streamlined permitting, set a minimum wage for employees constructing large-scale utility projects, and included an environmental justice provision to keep energy from waste incineration plants in frontline communities from counting toward the 2040 goal. Minnesota continued “crushing it on climate action” in the months that followed, with Walz securing a $2 billion budget package that included grid improvements, solar panels on state-owned buildings, an electric-vehicle rebate program, heat pump grants and rebates, a green bank, and more. He also signed a transportation bill to overhaul transit hubs, expand passenger rail service, improve infrastructure, and offer electric bike credits.
And he hasn’t stopped. Earlier this summer, Walz announced a $200 million grant to reduce food-related pollution, including protecting and restoring carbon-absorbing peatlands, improving food waste programs, and replacing gas-powered agricultural machinery with trucks that run on electricity or clean fuel. The state is also considering bills that would reform building codes to improve access to affordable housing — an issue Walz has taken a personal interest in. Walz is also, apparently, a YIMBY on energy permitting.
YIMBYs to the white house!
"We have permitting that takes too long...and prohibits or makes more expensive doing renewable energy projects. I think that same thing applies to housing. We put up barriers to making it more affordable." - Democratic VP Candidate Tim Walz https://t.co/MAiy3Ct5B5 pic.twitter.com/EnswfMw67g

Walz’s canny communication skills have already been much remarked upon, and he’s openly recognized that many on the left struggle with a messaging problem regarding climate change. “The surest way to get people to buy in is to create a job that pays well in their community,” the governor told Time’s Justin Worland. “All of us are going to have to be better about our smart politics, about bringing people in.”
Walz’s record isn’t spotless, though. During his congressional career, he earned a score of just 75% from the League of Conservation Voters. Earlier this summer, a coalition of 16 environmental groups, including the local Sierra Club chapter, called out Walz and his administration for being too soft on regulation, including state agencies’ reliance on farmers voluntarily complying with nitrate pollution limits, the Minnesota Pollution Control Agency’s failure to adequately police air quality violations from a foundry in a low-income neighborhood, and what the group argued was a flawed permitting process for a crude oil pipeline built through wetlands. North Dakota Republicans — including Governor Doug Burgum, who’s been floated for a potential Trump cabinet — have pressured Walz to include carbon capture as a carbon-free energy technology under the state’s emissions law (currently, decisions over CCS and hydrogen are under the purview of Minnesota’s Public Utilities Commission).
There’s also the small matter that Harris and Walz have to actually win to be able to enact any of their climate goals. At least on paper, the math had looked slightly better for Pennsylvania Governor Shapiro, who is an incredibly popular governor in a must-win state. “Minnesota is very unlikely to be the tipping point state — less than a 1% chance,” Nate Silver wrote Tuesday morning, arguing that Shapiro would have been a better pick despite mounting criticism from progressives.
Within hours of the news, though, the climate left had already enthusiastically circled around Walz. In a statement, Evergreen Action Executive Director Lena Moffitt applauded Walz’s “masterclass in how to govern in a way that meaningfully improves people’s lives and sets the state up for a thriving future.” Cassidy DiPaola, the communications director at Fossil Free Media and a spokesperson for the Make Polluters Pay campaign, likewise acknowledged Walz’s progress on green issues, nodding to his “evolution into a climate champion.” She added that Walz has more than proven himself at the state level and that “his ability to connect climate policy to the everyday concerns of Midwestern and rural voters could prove invaluable in building broader support for climate action.”
That, after all, will be the big question. Early voting for the next president of the United States begins in 41 days.

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.
