“This is Sky Valley Fire. Evacuation alert for Bolt Creek Fire. GO! No time for delay. Load up your family and pets and LEAVE NOW.”
Imagine getting an alert like this on your phone. Your heart immediately starts pounding; your hands shake. Is it real? Could this actually be happening? All the while, as your head spins, you’re losing precious minutes of time.
Luckily for many of the people who received this actual message last year in the Seattle suburbs, the “go now” alert was a mistake. But if you live in an area with anything greater than a “low” risk of wildfire, you should have a plan in place for what to do if that alert does come. It’s far better to “overreact” and leave immediately than to risk your life — and the lives of first responders.
The good news is, wildfire evacuation plans can begin long before your phone ever buzzes with that dreaded alert. Preparing for fire season ahead of time takes, cumulatively, as little as 90 minutes — but when a fire is encroaching, the math becomes far more urgent.
Importantly: Do not wait for an evacuation notice if you feel like a fire is approaching or like you could be in danger. Trust your gut and leave immediately. Though agencies do their best to protect people with advanced notices, fire is fast and unpredictable. In fact, many survivors of the deadly fire in Lahaina, Hawaii, say they did not receive evacuation orders before the flames had closed in on them.
Here’s what to do if there’s a fire in your area:
If you are experiencing smoke from a wildfire at your home, you should be paying attention to its development — the hazards of wildfires, after all, start with the smoke. If the fire is within 20 miles of you, you should definitely start paying attention; and if it is within 10 miles of you, it’s a threat. This threat increases if you are downwind or uphill.
Do not underestimate how fast a fire can move: 6 miles per hour in forests and up to 14 miles per hour in grasslands, depending on conditions. Embers, which can ignite homes, can also travel several miles, and wind direction can also quickly shift. If a nearby wildfire is approaching the 10-mile range of your home but you haven’t received a voluntary evacuation notice or don’t feel directly endangered yet, still review this evacuation checklist from the U.S. Forest Service. If you do receive a pre-evacuation alert or notice of some kind or want to take further steps to prepare, also:
Make sure you are signed up for emergency alerts or have another way of receiving updates, such as an agency website or Twitter account or a radio tuned into the correct station. Turn the sound on and up on your phone so you’ll hear the alarm or it will wake you up if you’re asleep.
Keep your car charged or filled to half a tank of gas or more. Scope out potential evacuation routes ahead of time, planning alternative routes in case roads are blocked or closed. Authorities say you should memorize at least two ways out of your neighborhood and avoid sketchy shortcuts that might be dangerous or blocked. Otherwise, take the quickest route to the main road, highway, or freeway out of the area.
Make a plan of where you’ll go if you need to leave your home for an extended period of time. A family or friend’s house? A hotel? A community emergency shelter? Open Red Cross shelters can be found here.
Open your garage door so you’re easily able to leave if you lose power.
Round up pets and secure them so they’re easy to put into carriers and transport to the car if you need to evacuate, and so you don’t waste precious time trying to chase them down when they’re scared. As the U.S. Forest Service notes, “this is especially important with cats.”
Prepare livestock and horses, if applicable, by reviewing this checklist.
Load up your car so you are prepared to leave on short notice. Remember to pack your go-bag (here is a version of the list in Spanish); suitcases of clothes and medicine (enough for at least a few days); pet supplies like collars, food, and water bowls; important files and back-up disks; insurance and bank papers; special or sentimental items; valuable jewelry or heirlooms (or store them in a fireproof safe); photo albums; and household items like keys and purses.
Too much to remember? Washington State suggests running through the Five P’s of evacuation: People, Prescriptions, Papers, Personal Needs, and Priceless Items.
Strongly consider leaving immediately. Roads can get congested after a mandatory evacuation order is issued, potentially creating dangerous situations where you’re trapped in your car near the fire. It will also get more difficult to see as the fire gets closer and the smoke gets thicker (always evacuate with your headlights turned on). Evacuating early also gives you time to calmly prepare a plan and collect essential items. If you’re on the fence, keep in mind it’s always better to leave too early than too late.
If you have time to prepare your house ahead of your evacuation, here is a checklist from the Western Fire Chiefs Association that you can use to get ready. Keep in mind that “the accepted sequence for safe evacuation is people first, then pets, livestock, and finally property,” Idaho Firewise writes. Major steps include:
Close all windows and interior doors to prevent the spread of fire indoors if the flames reach your home, and remove any curtains from windows. Close shutters and blinds. Leave your exterior doors unlocked so firefighters can get inside if need be.
Turn on all the main lights in your house as well as outdoor lights. This will allow firefighters to be able to see and navigate around your home in smoky conditions.
Push flammable furniture away from walls and windows and to the center of the room.
Shut off gas and turn off pilot lights. Don’t forget about pilot lights in gas fireplaces.
Attach hoses to outdoor water sources — firefighters will potentially use these to defend your home. The Western Fire Chiefs Association also recommends turning the nozzle to “spray” and propping a non-flammable ladder against your house to provide roof access. Fill buckets or garbage cans with water and leave them around your property if you’re able. However, you should not leave any water running, KQED notes, since that decreases the flow available to firefighters.
Prepare yourself for evacuation. California’s ReadyForWildfire.org recommends wearing “long pants, [a] long sleeve shirt, heavy shoes/boots, [a] cap, [a] dry bandanna for face cover [or a leftover COVID mask], goggles, or glasses,” and notes that “100% cotton is preferable.”
Finally, check on, text, or call neighbors and make sure they’re aware of the fire and also prepared to leave. Let them know you are choosing to evacuate. Also email, text, or call family who live outside the area and might be worried about you to let them know of your plans.
There is only one thing to do: Leave as fast as you can.
If you get an evacuation notice (or hear the high-low siren that also signals an evacuation order in California), do not waste time checking to see if the alert is real, gathering up items around your house, or making efforts to prepare your home. Your only focus at this point should be on getting to safety as quickly as you can.
Grab your go-bag and pets and get in your car; drive with the headlights on and follow the directions of any fire or emergency officials. If you need to evacuate on foot, quickly change into long pants, a long shirt, a cap, and heavy boots, and take essential items in a backpack or easily carried duffel bag. Know what to do if you get trapped near a wildfire. Be careful of downed powerlines or other hazards. And stay out of the area until officials say it is safe to return.

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.
