Kamala Harris quickly rang up endorsements from Democratic elected officials and convention delegates Sunday afternoon after President Joe Biden ended his re-election campaign, making Vice President Harris the likeliest Democratic nominee for the presidency of the United States. Many of these plaudits came from figures in the climate policy space, but few were quite as vociferous as the one from Gina McCarthy, a director of the Environmental Protection Agency under President Obama and White House climate advisor under Biden.
“Vice President Harris would kick ass against Trump,” she said in a statement. “She has spent her whole life committed to justice, fighting for the underdog, and making sure that no one is above the law. She will fight every day for all Americans to have access to clean air, clean water, and a healthy environment.”
When Harris has had the chance to formulate climate action on her own — as the attorney general of California, as a U.S. senator, as a candidate for the Democratic presidential nomination in 2020 — it has tended to be aggressive in its timelines for decarbonization and heavily focused on the harms that fossil fuel extraction and processing inflict on marginalized communities.
As vice president, however, she has been subsumed into the rollout of both the Inflation Reduction Act and the Infrastructure Investment and Jobs Act. In some cases, the programs she’s pitched and praised have an organic connection to her own personal policy work — a grant program for electric school buses, for instance, the launch of which was the source of one of her more enduring Kamala-isms: “Who doesn’t love a yellow school bus?”
Assuming she wins the party’s nomination and then, finally, the White House, a Kamala Harris climate agenda would no doubt look much like Biden’s. To people who’ve been paying attention all along, however, there’s no reason to think she couldn’t push the country even more zealously toward decarbonizing.
For one, there’s the historical record. Harris not only endorsed Green New Deal legislation in 2019, she also put out a climate plan during her campaign that included $10 trillion of public and private spending and called for reaching net-zero by 2045, achieving a carbon neutral electric grid by 2030, no new fossil fuel leasing on public lands, and a carbon pollution fee. While expansive, Harris’s plan was not the work of someone like Jay Inslee, who has legislated on climate for years, or Bernie Sanders, who was willing to simply outbid his fellow candidates on progressive policy, but her climate policy was the process of consulting with climate activists. In fact, her team had reached out to Inslee’s after he dropped out for advice on climate, Jamal Raad, Inslee’s campaign communications director, told me.
“If we jump in the Wayback Machine, [Harris] was one of the most ambitious presidential candidates in the 2020 primary cycle,” Justin Guay, program director at Quadrature Climate Foundation, told me. “She had the largest proposed spending plan of any candidate not named Bernie. She promised a sum 10 times that of the greatest climate president we’ve ever had, Joe Biden.” Importantly, he added, she focused on “sticks, not just carrots,” including investigating and bringing lawsuits against fossil fuel companies, as she’d done in California. This, he said, is “red meat for the climate base.”
Where she did stand out in the Senate, on the campaign trail, and in the Biden administration was in her focus on environmental justice, an issue combining green politics and racial justice that she used to reach out to the party’s left wing. By the time the she was picked to be President Biden’s vice presidential nominee, she had won the praise of both the youth-led Sunrise Movement (which has since protested outside her Southern California home and notably withheld its support from Biden during his reelection campaign) and Evergreen Action, a climate policy group built by former Inslee staffers. “She made environmental justice central to her climate plans on the presidential campaign,” said Raad, an Evergreen Action cofounder.
In the summer of 2019, she joined up with Alexandria Ocasio-Cortez on a bill that would have required all climate-related legislation to undergo a review of its effect on “frontline communities,” those living adjacent to energy-related facilities, which tend to be disproportionately populated by poor people of color, and created offices of climate equity within the Congressional Budget Office and the Office of Management and Budget.
While this particular piece of legislation went nowhere, the motivating ideas have been all over the Biden-Harris White House’s policy agenda — in tax benefits directed toward projects in “energy communities;” in the Justice40 Initiative, which aims to direct 40% of climate and related spending to flow toward disadvantaged communities; and in the Greenhouse Gas Reduction Fund, a.k.a. “green banks,” aimed at making climate-friendly investing more affordable.
That’s all great, Raad told me. But he also added, “What’s more relevant has been how central she’s made climate in her vice presidency as one of her top priorities.” Harris reached out to Raad and others in the run-up to the IRA’s passage, he said. “She held a town hall. She barnstormed the country. As far as folks wanting further momentum in the next presidency, that’s the more relevant development — that she wanted to be associated with climate action.”
Whatever her policy priorities as president, they would have to fit between the lines of what would be, at best, narrow majorities in both chambers of Congress, limited by the filibuster and reconciliation process, along with large policy shifts that any new administration will have to deal with, such as the expiration of key portions of the 2017 Tax Cuts and Jobs Act in 2025. It will be a far distance from the heady days of the 2020 Democratic primary campaign, when Harris eagerly participated in a bidding war between the candidates for the most aggressive and expansive climate program — less Frank Capra, more Alan J. Pakula.
“The reality is that the climate movement should focus as much, if not more, on creating the conditions that force politicians to act on climate as we do pushing for candidates with a hawkish climate policy platform to begin with,” Guay told me. “That was the greatest lesson from the Joe Biden era. He was no climate hawk when he entered the 2020 primaries,” but thanks to decades of unrelenting pressure and calls for more policy ambition, “he emerged the most powerful climate president we’ve ever had.”
Raad, too, emphasized the importance of realpolitik at this point in history. Having a president willing to put herself on the line for climate policy is important — “even if we don’t get major legislation done,” he told me. “We need to make sure the IRA is implemented effectively in the fullest way possible. We need a very careful eye towards writing regulations that are as effective as possible so they’re not getting overturned by Federalist Society judges.” Getting money out the door will be key, he said, “and that’s why we need an advocate in the White House.”

There‘s a striking amount of agreement across the political system about what the big issues are.
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.
The country's fastest-growing market for data centers is, for now, frozen. Governor Greg Abbott of Texas announced on Monday that the state’s grid authority should not allow any more data centers to hook up until state regulatory agencies complete an audit of existing projects.
As part of this audit, data center developers will have to disclose the following, according to the governor:
“Any data center project that fails to comply” with the audit “must be denied,” Abbott wrote in a letter to the agencies.
Abbott's freeze isn't quite broad enough to be called a full-on moratorium. As The Texas Tribune noted, data centers that aren’t asking to connect to Texas’ power grid can proceed as planned. But the announcement does mean New York is no longer the only state where the governor is trying to slow down data center development. As my colleague Alexander Kaufman wrote today in Heatmap AM, Texas’s governor has more than a little in common with New York’s chief executive, Kathy Hochul — above all, they’re both running for re-election in November.
Now, as far as data center regulation goes, Abbott's disclosure requirements are pretty weak tea. That’s chiefly because they are, well, disclosure requirements — they don't require that any developer actually changes their behavior, just that they publish data saying what they were going to do in the first place.
Yet his announcement put me in mind of something I've been thinking about for a while: There might be more agreement about data center regulation than we think.
Take Michigan, for instance. The progressive Senate candidate in that state, Abdul El-Sayed (who could very likely win the Democratic primary tonight), has become prominent partly by speaking out about data centers. He was early to the topic, publishing mandatory “terms of engagement” for data center developers back in January, and his own rise has tracked the issue’s rising salience in American politics.
Some of El-Sayed’s recent remarks about data centers have an undertone of surprise, as if he is a little astounded by how prominent the issue has become. “There’s literally not a conversation that I have, not a stop that I make, where data centers and AI don’t come up,” he said last month. As he recently marveled on a campaign stop last week: “People really effing hate data centers.”
He hasn't called for a national data center moratorium, though, as his allies and endorsers Senator Bernie Sanders or Representative Alexandria Ocasio-Cortez have. Instead, his blessedly short document says Michiganders should have a few “rights” when a data center wants to build in their community:
He’s also called for an end to tax breaks for data centers.
El-Sayed is on the Democratic Party's left. Earlier today, a candidate seen as in the party’s center — Iowa gubernatorial candidate Rob Sand — released his own data center plan. It demands the following, at somewhat greater length:
Look — it’s pretty similar to El-Sayed’s list! Sand might be a moderate, and El-Sayed might be a progressive, but it’s hard to see too much daylight between their data center policies.
What’s notable about these policies is what’s not in them. Neither El-Sayed nor Sand would require that data centers be powered by clean energy, as, say, the Wisconsin DSA gubernatorial candidate Francesca Hong has proposed. Neither El-Sayed nor Sand moots a statewide moratorium on data centers, either. And while their proposals would have more teeth, in theory, than Abbott’s audit, the three proposals are interested in the same questions — energy use, water use, physical footprint, and tax incentives.
As we’ve frequently noted at Heatmap, the data center backlash is strikingly bipartisan. Americans of many backgrounds, belief systems, and byways of life agree that the data center boom is becoming a problem. I wonder if there’s more agreement about the solution, too, than we might think.
The state’s crystal clear lakes are turning into the Reflecting Pool.
Life is a constant process of dying — even for lakes. For Lake Kanasatka, a 350-acre body of water born when the glaciers raked their retreat into the bedrock of what is now New Hampshire, everything nearly came to an end in 2023.
The first sign that something was wrong appeared in 2009. That November, the state’s Department of Environmental Services noticed a “green scum” in the water near Camp Quinebarge Beach. Over the next few years, the DES continued to dutifully report the emergence of “greenish slime” along the shoreline until, in August 2020, the concentration reached a level that prompted the lake’s first warning of a toxic algae bloom.
In recent years, many lake-loving Americans have added that term — “toxic algae bloom” — to their summer lexicon. It’s also a bit of a misnomer: the culprit, cyanobacteria, are not technically algae but ubiquitous single-celled microorganisms, their photosynthetic chlorophyll and an additional pigment giving them the blue-green appearance suggested by their name. “They’ve been around forever,” Amanda McQuaid, a water quality ecotoxicologist at the University of New Hampshire and director of the school’s citizen-science lake monitoring program, told me. “I personally think they’re probably on Mars. I think they’re everywhere. They’re indestructible.”
Cyanobacteria are present across habitats, from the Sahara dust in Africa to the shelves of our grocery stores to the Lincoln Memorial Reflecting Pool in Washington, D.C. (The Trump Administration can attest firsthand to their indestructibility.) What transforms a healthy concentration of cyanobacteria in a lake into a bloom is access to nutrients — specifically phosphorus, which enters lakes via runoff from fertilized lawns or farms, leaky septic tanks, pet waste, and eroding shorelines. As lakeside living has increased in desirability and housing development has encroached on natural bodies of water, blooms have consequently followed.
Though the Centers for Disease Control and Prevention does not keep an official count of cyanobacterial blooms, a conservative estimate puts the number of advisories issued nationally in the hundreds, and more likely in the thousands, every year. Cyanobacteria are a class of organisms with thousands of species, like plants, but many produce toxins as part of their metabolic processes. These toxins are numerous and include microcystin, which affects the liver and can cause skin irritation and gastrointestinal problems upon contact with swimmers and waders, as well as anatoxin, a neurotoxin that can kill a dog within minutes of it lapping up contaminated lake water on a hot summer day.
Most alarming, though, is that many cyanobacteria also produce the neurotoxin BMAA, which can become airborne and which researchers have connected to neurodegenerative diseases in humans. According to another study by Dartmouth-Hitchcock Medical Center neurologist Elijah Stommel, people living within a half-mile radius of cyanobacterially contaminated lakes had a 2.3-times greater risk of developing the devastating and terminal nervous system disease ALS compared to the rest of the population. In the case of one contaminated lake near Enfield, New Hampshire, the incidence of sporadic ALS was 10 to 25 times above what was to be expected. And in a state like New Hampshire, which was gouged by the glacial retreat at the end of the last ice age, nearly 80% of residents live within half a mile of some body of water.
Scuzzy green water occurs in every state in the country. Nationally, the Environmental Protection Agency detected the telltale microcystin toxin in 39% of U.S. lakes in a 2012 survey; by the EPA’s most recent survey, in 2022, that number had risen to 50%. Still, in places like New Hampshire, cyanobacterial blooms are a relatively new phenomenon, having recently intensified due to increased development and climate change. “People are not used to going to a lake in New Hampshire and not being able to see through the water,” McQuaid said. “So if things are green or scummy or turbid, they’re like, ‘What is happening?’”
Between 2001 and 2008, Andrea LaMoreaux worked for the state’s Department of Environmental Services, running a water-quality testing program. She told me that during that time, she saw only one lake with a cyanobacterial bloom. But by 2015, blooms had become a topic of conversation in the state, and by 2023, just three years after its first toxic algae advisory, Lake Kanasatka was in a full-blown crisis.
“This is a lake that had a reputation for always being pristine — a very quiet lake,” state Representative Rosemarie Rung, who represents nearby Merrimack and owns a seasonal cottage on Kanasatka, told me. But 2023 was markedly different: the bloom was bad enough to dissuade recreation for weeks on end — in the “Live Free or Die” state, the DES doesn’t close beaches, even due to blooms. One woman described the feeling of her lips going numb while kayaking.
Kanasatka had crossed a tipping point. As part of a lake’s natural aging process, organic debris settles on its floor and decomposes, eventually consuming all the oxygen in the water. When that happens, phosphorus normally bound to iron in the sediment is released into the water — where it in turn provides extra nutrients for cyanobacteria. While human-caused inputs like runoff might previously have limited the cyanobacteria, lake anoxia offers them a firehose of nutrients to feast upon.
The tipping point is around 10 parts per billion of phosphorus in the water; in Kanasatka in 2023, there was around 200 parts per billion. “All of a sudden, [Kanasatka residents] woke up one morning and literally almost overnight, it looked like someone had dumped Mountain Dew into the lake,” LaMoreaux, the former DES employee who now serves as the president of NH Lakes, a statewide nonprofit lake conservation and advocacy group, told me.
Left untreated, Kanasatka would have slowly suffocated, with dead cyanobacteria adding to the decomposing organic matter at the bottom of the lake and blocking light to lake plants, making the anoxia worse. But there is one reliable way to treat a cyanobacteria bloom: with alum.
Phosphorus breaks apart from iron in the absence of oxygen, but it binds permanently with aluminum. An alum treatment, then, involves coating the lake bottom with an aluminum-heavy chemical concoction and is one of the only ways out of the slimy green cyanobacterial feedback loop. But so-called “biomanipulation” also has unknown downsides — including potentially spurring cyanobacteria to release more toxins as they rupture — and it isn’t cheap, either, running about $500,000 in the case of Lake Kanasatka. Rung, who helped create a $2 million cyanobacteria mitigation fund to support alum treatments across the state, told me it helped with Kanasatka’s treatment and “another alum treatment for a lake in Littleton, New Hampshire, which also had suffered very severe chronic blooms. But then the money ran out.”
But while Kanasatka today is the state’s poster child for algae blooms — it appears healthy two years out from its treatment, although alum only lasts about two or three decades — it wasn’t a one-off, either. During the COVID-19 pandemic, many people moved to New Hampshire’s lakes to work remotely, fertilizing new lawns and cutting down shoreline brush to better enjoy their views in the process. That’s sped up the encroachment of cyanobacteria across one of the country’s healthiest lake systems.
There is another powerful factor driving the blooms, and it is out of New Hampshirites’ hands alone. Climate change supercharges cyanobacteria blooms, with a strong correlation between hotter, sunnier summers and high concentrations of the warm-water-loving, photosynthetic microorganisms. Even more crucially in a state like New Hampshire, milder winters mean fewer weeks of ice cover on its lakes — cover that essentially acts as a “reset” by depriving cyanobacteria of sunlight. And heavier rains and flooding in New Hampshire, phenomena that greater water retention in a warmer atmosphere makes possible, mean greater runoff into the lakes and a firehose of food for the waiting microorganisms.
Unchecked, cyanobacteria pose a threat not just to human and animal life, but to the lives of recreation-based towns and economies. “I know anecdotally that people who have rented a lake house for a week or so, and there’s been a bloom, have been very, very angry,” Rung, the state representative, said. “They’ve tried to get out of that rental and get their money back, and there has not been guidance on what to do. Pretty much, they’re out of luck.”
But political will and funding challenges are real — Rung tried and failed to create a lake-lovers vanity plate to help pay for future mitigation treatments, and a recent deadline to create a task force to identify other funding sources expired with no progress.
“People don’t even want to say the word climate change in New Hampshire,” Rung told me in frustration. “Even the terminology triggers people, but it can’t be ignored. We’re just a small state. We don’t have a big population. We can’t do anything about it. But yet, we’re suffering the consequences.”
On Texas data centers, Microsoft’s carbon removal, and cross-border aluminum
Current conditions: Dangerous degrees of wildfire smoke swept into the Pacific Northwest, leaving air quality in fire-struck Spokane, Washington, at very unhealthy levels through midweek • Yesterday’s thunderstorms across the Northeast grounded flights and delayed thousands of passengers as key airports in New York City, New Jersey, and New England halted incoming arrivals for hours • Temperatures in Abu Dhabi are soaring to nearly 110 degrees Fahrenheit all week.

Europe’s rivers are running dry amid the prolonged drought and third major heat wave this summer. On Monday, the Rhine River’s water levels dropped to their lowest level in nearly 150 years, beaching cargo barges and jeopardizing output from the various thermal power plants that line the waterway stretching through France, Germany, and Switzerland. The water levels at Kaub, a key crossing for vessels heading to southern Germany and Switzerland, fell to 24 centimeters, the lowest level since records started in 1880, according to a Bloomberg analysis of German federal data compiled by the university ETH Zurich. In Eastern Europe, the Danube’s flow is so depleted that just one reactor at Hungary’s only nuclear station, the four-unit Paks plant, is operating — and only at 50% as cooling water dwindles, NucNet reported.
In Washington State, meanwhile, nearly 65,000 people have now been evacuated from the wildfires that incinerated almost 700 homes in the Spokane area with a “wall of flames.” As of Monday evening, the fire was still 0% contained, according to Fox 13 Seattle, a local broadcaster.
You might not think it, given the partisan politics of our age, but the governors of New York and Texas actually have a lot in common. New York Governor Kathy Hochul is a Democrat, and Texas’ Greg Abbott is a Republican. But they’re both pro-nuclear. They’re both up for reelection this year. And they’re both banning data centers, at least temporarily. Last month, New York became the first state to halt permitting on new, large data centers for a year. Now Texas has put approvals for new data centers on hold until the state’s power regulators and grid managers can audit existing facilities that are seeking to connect to the state’s grid. Until then, E&E News reported, “no more additional data centers can be approved or move forward until that process is over.” In a letter to both the Public Utility Commission of Texas and the Electric Reliability Council of Texas, Abbott wrote: “Any project that fails to comply with the requirements set forth by the PUC and ERCOT, and by state law, must be denied connection to the Texas grid. Simply put, Texans must come first.” On the local level, moratoriums on data centers blossomed in recent months, with more than 530 municipalities having slapped new restrictions on server farms, per a recent Heatmap analysis my colleague Robinson Meyer wrote.
Hochul, as our colleague Matthew Zeitlin wrote later last month, is “walking a fine line” with her moratorium, issued via executive order, especially as her administration seeks to appease renewables boosters who say she isn’t doing enough to speed up deployments of that kind of infrastructure. But blocking disfavored types of infrastructure is nothing new for the Texas GOP. Lieutenant Governor Dan Patrick is among the big names now trying to thwart a $33 billion transmission buildout in the state.
Back in April, Rob broke news that Microsoft was pausing its carbon removal purchases. The break marked a major setback for a nascent industry that had come to rely on the tech giant as its biggest and deepest-pocketed source of demand. While the company never confirmed the pause, it appears to be ending. Last night, my colleague Emily Pontecorvo passed along a big exclusive for this newsletter: Microsoft is set to announce a big carbon removal purchase. CREW Carbon, the Brooklyn-based startup that permanently traps carbon dioxide using a limestone and wastewater mix, inked an offtake agreement with Microsoft for 23,602 “durable, verified” credits. CREW “uses strategically-sourced alkaline minerals, such as calcium carbonate, to optimize key conditions, like pH and alkalinity, in each wastewater treatment plant’s specific process to minimize the carbon footprint of plant operations,” the company said in a press release shared in advance with Emily.

As my colleague Katie Brigham reported last week, Commonwealth Fusion Systems made waves in the clean energy financing world for yet again raising an eye-popping $1 billion to commercialize fusion energy, notably bringing on institutional investors for the first time. Now another fission startup is bringing in a similar chunk of coin. California-based Valar Atomics just pulled in $1 billion to help bring its next-generation high-temperature gas-cooled microreactors to market. The venture capital giant Sequoia led the round, and added the firm’s Shaun Maguire to its board.
Even with progress on nuclear, the future for gas continues to look rosy. On Monday, Utility Dive reported that American Electric Power now has 13 gigawatts of gas turbine capacity in the pipeline.
Zerluma, a Mexican aluminum recycler, has broken ground on a new $50 million facility in Mission, Texas, the San Antonio Business Journal reported. The deal in the city near Texas’ southern border, marks one of the largest private investments in the city’s history, according to the Rio Grande Valley Business Journal.
The agreement comes as the Trump administration seeks to support the opening of the first new American aluminum smelter in half a century, a project that — as you may recall — has attracted scrutiny from state Republicans in Oklahoma. The effort is facing yet more criticism. The Muscogee Nation’s National Council voted unanimously to approve a resolution opposing aluminum smelters on tribal land following the Trump-backed proposal for a $4 billion plant by Emirates Global Aluminum. Last month, city leaders in Port of Inola approved a 60-day moratorium on smelter-related construction, according to the Tulsa broadcaster News On 6.
The United Kingdom has a coke problem: The snortable white stuff is too good and too cheap. So, what is a criminal enterprise that needs something tradeable of high value to do? Well, increasingly, they’re going for gold. Illegal gold mining has replaced cocaine as organized crime’s most profitable business, according to Mining.com. That has grave implications for human rights — and for communities in places such as the Amazon.
