Extreme heat is the deadliest weather phenomenon in the United States. It's also one of the easiest to underestimate: We feel it on our skin, or perhaps see it shimmering in the air around us, but it doesn't announce itself with the destructive aplomb of a hurricane or wildfire. Still, heat waves are becoming practically synonymous with summer.
Climate change is only making heat waves worse. They're getting more frequent, up from an average of two per year in the United States in the 1960s to six per year in the 2010s and '20s. They're also about a day longer than they were in the ‘60s, and they're more intense; those two factors combined, in particular, make them more deadly. This year's expected El Niño will bring even more heat with it: NOAA's summer outlook for the United States, shown below, paints a swath of above-average temperatures across much of the country.
NOAA's seasonal temperature outlook for the summer of 2023.National Oceanic and Atmospheric Administration
I’ve spent a lot of time thinking about how to cover heat waves. Each is unique — suffering of any kind is always unique, even if the broad strokes are not — yet the things one can say about them are, for the most part, largely the same. Records will break, power grids will strain, and people will be hurt: This is the reality of climate change.
So this year, we are trying an experiment: We will document particularly notable heat waves around the world as they happen, but rather than devote separate stories to them, each heat wave will get a short entry within this larger page. We will call out especially vivid details or statistics and include links to local outlets that can provide more information to anyone looking for it.
The goal here is to create a record of the very real impact of climate change today. By the end of the summer, this page will likely be filled with entry after entry showcasing the ways heat affected people around the world over the course of a few months. This is, I am aware, potentially fertile ground for climate anxiety, but our hope is that the project can help us recognize how our lives are changing and allow us to refocus on what we can do to adapt to our new reality.
Each entry has its own URL. If you wish to share details of any particular heat wave, simply scroll to that entry and hit the share button on your phone or copy the link in your browser. If you'd like to share this tracker as a whole, scroll back up to this introduction. This timeline will be in reverse chronological order, or in other words the newest events will appear at the top of the page.
This project is publishing in the midst of a heat wave hitting multiple Asian countries, and we’ve also included a couple of heat waves that have already come and gone; as the summer progresses, you'll see updates from the entire Heatmap staff and the gradual shaping of a larger story of heat. Again, this is an experiment, and we'd love to hear what you think about it — if you have strong thoughts one way or another, please send them to neel [at] heatmap [dot] news. —Neel Dhanesha
September 6: As we near the end of the summer — though ambient temperatures this week may suggest otherwise — the World Meteorological Organization (WMO) has announced that Earth just had its hottest three-month period on record, and the year so far is the second-warmest after 2016, which saw an extreme El Niño.
“Climate breakdown has begun,” said UN Secretary-General António Guterres in a statement. “Leaders must turn up the heat now for climate solutions. We can still avoid the worst of climate chaos — and we don’t have a moment to lose.”
According to the Copernicus Climate Change Service, August is estimated to have been around 1.5°C warmer than the preindustrial average. Last month saw the highest global average sea surface temperatures on record, at 20.98°C, and Antarctic sea ice was at a record low for that point in the year. Those sea surface temperatures will have a significant impact on hurricane season; as we saw with Idalia, extremely high ocean temperatures can supercharge tropical storms.
These numbers are no surprise — scientists have, of course, been warning of these catastrophic impacts for years — and this report is just the latest in a long line of UN reports that catalog the ways our planet is changing. The question, as always, is if this report will spur any more action than the previous ones did, or whether it will amount to yet another howl lost in the wind. —Neel Dhanesha
August 23-28: On Thursday, record-breaking heat tied the hottest temperature ever recorded in Houston at 109 degrees. In Dallas on Friday, highs climbed into the high 100s. And in Austin on Sunday, the temperature climbed up to 109 degrees. From Thursday to Sunday, the Electricity Reliability Council of Texas issued a conservation request every day — asking Texans to lower their energy use as air conditioners blasted.
Texans will get a relative reprieve from the heat over the coming days: Dallas won’t cross back over the triple-digit mark until Saturday, while Houston won’t get hotter than 100 degrees this week. Still, temperatures remain high — a reminder that just because summer break is over in many places, summer weather isn’t, making air conditioning in schools and on buses more critical than ever. —Will Kubzansky
August 22: The Midwest joins the South and Southwest this week in pulling the short straw of weather forecasts. The National Weather Service projects a large heat dome will “persist in at least 22 states until the end of the week,” Axios reports, affecting 143 million Americans. Numerous cities are experiencing heat indexes between 110 and 115 degrees Fahrenheit; Lawrence, Kansas, even reached a “feels-like” temperature of 134 on Sunday.
Not only will the extreme highs endanger lives, the heat waves might threaten “a bumper U.S. harvest that’s key to keeping global inflation in check,” Bloomberg reports. The United States expects to reap its second largest corn harvest on record this year, but the upcoming heat might dry out fields that are already showing signs of being parched.
Over the weekend, relief for the Midwest will come from cooler winds flowing down from Canada, AccuWeather reports. Unfortunately, the welcome breeze might also come along with “bouts of poor air quality” and smoke from Canadian wildfires. —Annie Xia
August 16: With triple-digit highs, the Pacific Northwest has joined the ranks of states breaking heat records this summer. Portland, Oregon, hit 108 degrees Fahrenheit on Monday, a record for the month of August. Seattle, Washington, also set a new daily record on Monday when it reached 96 degrees.
Combined with strong winds and moderate to severe drought levels, high temperatures in the region also mean heightened wildfire risk. Almost 3,000 firefighters are already “battling the seven large fires burning across Oregon and Washington,” CNN reports.
The sweltering temperatures continue a streak of oppressive summers in the Pacific Northwest. Dr. Steven Mitchell, medical director of a Seattle hospital’s emergency department, told The New York Times that “he couldn’t remember treating a single case of severe heat illness or heat stroke” before 2021, when a deadly heat wave struck the region. —Annie Xia
August 9-11: Florida is often synonymous with heat, but the heat index in Tampa Bay climbed up to 112 degrees on Wednesday — flirting with 113, the mark at which an excessive heat warning is issued. The Tampa Bay Times reported that the warning issued Wednesday was possibly the area’s first excessive heat warning ever, with the caveat that records might be faulty.
While the heat has let up slightly, a heat advisory remains in effect from Fort Myers up to Chiefland, and the area has exceeded its electricity demand records twice this week. On Friday, the heat index at Tampa International Airport reached 110 degrees, and values are expected to climb up to 108 on Saturday, according to the National Weather Service. —Will Kubzansky
August 7: In places like New Orleans, the old adage applies: It’s not just the heat, it’s the humidity. The high is set to hover between 100 and 97 through Friday, but the heat index will sit between 116 and 111. Louisiana, like much of the country, is seeing an unusually hot summer: Baton Rouge experienced its warmest month on record in July. All the while, central Mississippi is experiencing highs between the high 90s and low 100s, with heat indices reaching 120 degrees, according to the National Weather Service’s outpost in Jackson.
The heat killed 16 Louisianans in June and July. And given that extreme heat causes the worst impacts for people experiencing poverty and creates particularly devastating effects for Black Americans, it’s worth noting that Mississippi and Louisiana have the two highest poverty rates in the country as well as the highest proportion of Black residents of any two states. —Will Kubzansky
August 2: Iran is shutting down. The New York Times reports that government agencies, banks, schools, soccer leagues are all closed Wednesday and Thursday, allegedly due to the heat, which is expected to reach 104 degrees Fahrenheit in Tehran. In Ahvaz, a southwestern city, the high on Wednesday is a blistering 123 degrees.
Per the Times, some Iranians have expressed doubts about the alleged reason for the shutdown — instead claiming that the country’s electric grid can’t meet demand. All the while, Iran faces extensive water shortages across the country, largely due to mismanagement of its resources. —Will Kubzansky
August 2: A deadly heat wave is striking both sides of the Sea of Japan.
In South Korea, two deaths were reported on Tuesday due to high heat — they were senior citizens working outside — bringing the death toll from the heat wave to 12. With temperatures above 100 degrees Fahrenheit in Yeoju, a city south of Seoul, the country has raised its warning system for heat to the highest level, the first instance since 2019.
And in Japan, a 13-year-old girl and an elderly couple died due to heat-related causes on Friday. Temperatures have climbed above 103 degrees this week in parts of the country, and 32 prefectures are under the government’s “special heatstroke alert,” according to The Washington Post.
Japan is coming off a brutal month of July, which included the longest run of 95 degree temperatures in Tokyo since records began in 1875. Heat waves are especially devastating for Japan, which has one of the world’s oldest populations. —Will Kubzansky
July 28: No American city has been more emblematic of this summer’s relentless heat than Phoenix, where the temperature has climbed above 110 degrees Fahrenheit for 29 consecutive days. That streak looks like it might finally come to a close, with highs ranging from 106 to 109 from Monday to Wednesday next week as the forecast calls for rain over the weekend. But by Thursday, the mercury will climb above 110 yet again.
With the heat showing no signs of truly relenting, Arizona Democrats have proposed a novel solution — calling on President Joe Biden to issue a presidential disaster declaration for extreme heat, unlocking the Federal Emergency Management Agency’s response capabilities. And all the while, more than 30 wildfires are blazing across the state of Arizona. —Will Kubzansky
July 26: For most of the summer, stories about extreme heat in the U.S. have been limited to the South and Southwest. That’s changed in the last few days, as heat is forecast to scorch the Midwest and Northeast this week. On Thursday, New York will see highs in the mid-90s and D.C. up to 99 — both with heat indexes in the mid-100s. In Kansas City, highs will sit in the 100s through Friday and climb back up into the triple digits again on Monday; Indianapolis will reach 99 degrees Friday.
Late July is an appropriate time for heat waves — and this burst does not look like a lengthy one, with the 10-day forecast dipping back into the 80s — but it’s also worth noting that cities like D.C. are less prepared for extreme heat than Miami or Phoenix. D.C. has entered a hot weather emergency, but in New York, some advocates have cautioned that the city is not ready for the challenges ahead. —Will Kubzansky
July 26: Devastating consequences of the climate crisis are playing out in Algeria, Greece, Italy, and Tunisia, as wildfires spread and take dozens of lives — more than 40 in total and 34 in Algeria alone. The wildfires are being driven in part by intense heat, up to 119.7 degrees Fahrenheit in Algeria and 120 degrees in Tunisia. While those temperatures have cooled slightly, they will reach up to 111 degrees in Tunis come Friday and already climbed into the triple digits in Greece on Wednesday. Meanwhile, Greek authorities have evacuated more than 20,000 people from Rhodes, a popular vacation spot. —Will Kubzansky
July 25: The summer has offered a deluge of heat headlines — scrolling through this page is the proof. But zooming out, the context matters: Has this summer’s heat been uniquely driven by climate change? The answer is almost certainly yes, according to a study from researchers at Imperial College London, the Royal Netherlands Meteorological Institute, and the Red Cross Red Crescent Climate Centre.
The flash study is not peer-reviewed — it moved too quickly to go through that process — but it notes that “without human-induced climate change these heat events would … have been extremely rare.” The high temperatures in North America and Europe, it adds, would have been “virtually impossible” without climate change. Heat waves may have still occurred, but the key is the intensity: In the U.S., Europe, and China, climate change accounted for between 1 to 2.5 degrees Celsius (1.8 to 4.5 degrees Fahrenheit) of additional heat. —Will Kubzansky
July 17: Records are falling left and right in the Southwest. At 118 degrees Fahrenheit, Phoenix broke its all time high temperature record on Saturday. The city is also approaching breaking its record for the most 110 degree days in a row. In El Paso, the temperature at the airport has hit 100 degrees for 32 consecutive days, the longest streak ever. And according to The New York Times, the National Weather Service called for 45 record highs across the U.S. last weekend.
And as wildfires burn in Southern California, the heat wave is showing no signs of letting up. Phoenix will see highs in the 110s through Monday, as will Las Vegas. At this point, the heat wave has been classified as another heat dome, and Texas is feeling the brunt of it too, with San Antonio and Austin under excessive heat warnings. The heat wave is most dangerous for vulnerable members of society, especially people who are homeless and seniors — placing an outsized and crucial burden on cooling centers in the Southwest. —Will Kubzansky
July 14: A year after Europe saw 60,000 excess deaths due to heat waves, according to a study published by the scientific journal Nature Medicine, Southern Europe is scorching again. In Greece, the Acropolis closed midday Friday to tourists with high temperatures in Athens expected to reach 104 degrees. Parts of Spain saw temperatures going up to 113 degrees Monday, and another heat wave is expected to arrive Sunday. Italy, in the meantime, is expecting that next week could break the record for the highest temperatures ever recorded on the continent.
Europe has taken a new approach to heat waves — giving them names like hurricanes in an effort to raise awareness about their severity, an idea my colleague Neel Dhanesha wrote about last year. The first round of heat this week was dubbed Cerberus; the second round set to arrive this weekend is named Charon. —Will Kubzansky

July 12: In a summer full of record-breaking heat, the fact that it’s hot in Death Valley is almost comforting. On Sunday, the national park in the Mojave Desert, known for being the hottest place on Earth, is projected by the National Weather Service to reach 130 degrees Fahrenheit, which would probably tie the record for the world’s highest temperature. The uncertainty stems from some controversy surrounding the record: While the valley was said to have reached temperatures of 134 degrees in 1913, experts have questioned the legitimacy of that reading. That leaves 130 degree days in 2020 and 2021 as the hottest temperatures on record — in Death Valley or anywhere.
While Death Valley’s heat is something of a novelty, it has catastrophic impacts elsewhere. Las Vegas’s high will only be 12 degrees cooler (118 degrees), and temperatures will reach 106 degrees on the same day in San Bernardino. —Will Kubzansky
July 10: After 10 days with high temperatures above 110 degrees, the highs in Phoenix are forecasted to eclipse that mark for at least the next nine days. According to the National Weather Service’s Phoenix office, the record for consecutive 110-degree days is 18; the office is placing the probability that the record gets shattered at 50%. And like Texas’ heat dome earlier this summer, evening temperatures aren’t declining as substantially as they usually do, leaving Arizonans without relief.
In New Mexico, the National Weather Service office out of Albuquerque is describing the week ahead as “near-record heat.” And temperatures in Las Vegas, Nevada, are set to get even more brutal over the course of the week, with the high going from 107 degrees on Monday to a forecasted high of 117 on Sunday. The heat will also lead to brutal temperatures in Death Valley — potentially up to 127 degrees on Sunday — according to the The Washington Post. —Will Kubzansky
July 10: Texas can’t catch a break this summer — and the South is catching yet another heat wave as well. Heat indexes in Dallas, Houston, New Orleans, and Miami are set to reach 107 to 108 degrees this week. Water temperatures around South Florida are well above average, and the chance that rain breaks the heat in the area is limited over the next few days. This year is already the hottest on record in Miami, according to WLRN. —Will Kubzansky
July 7: Phoenix and Tuscon are under excessive heat warnings for at least the next six days. Afternoon highs are projected to reach between 105 and 115 degrees Fahrenheit — Friday will get up to 112 degrees in Phoenix — bringing temperatures above average for early July, according to AZCentral.
It might last well into the month. According to the National Weather System’s warning: “We are still anticipating this current heat wave to continue through next week and likely beyond with it rivaling some of the worst heat waves this area has ever seen.” A big heat wave also brings pressure to the electric grid, particularly in heavily populated areas like Phoenix, as residents crank up their ACs. One study from earlier this year showed that a five-day heat wave and blackout would combine to send more than 50% of the city’s population to the emergency room.
It’s also not just Arizona that will catch the worst of this wave: New Mexico, Las Vegas and Death Valley all have scorching temperatures in store over the next week, The Washington Post notes. —Will Kubzansky
.
July 6: Outdoor work came to a halt in Beijing as temperatures reached 104 degrees Thursday in the Chinese capital. A heat wave is gripping parts of China, including the capital and the nearby Henan province. Before 2023, Beijing had experienced temperatures above 104 degrees six times, CNN reported. This year alone, the temperature has eclipsed that mark on five days. In Taiwan, temperatures are set to reach 104 degrees Saturday, according to the country’s Central Weather Bureau. All the while, flooding has also led to devastation in China, causing 15 deaths in Chongqing, Hunan province, and elsewhere. —Will Kubzansky
June 30 - July 5: In the Antelope Valley and Santa Clarita Valley, temperatures reached 105 and 101 degrees respectively Monday, the Los Angeles Times reported. David Gomberg, an NWS forecaster, told the Times that high heat is to be expected in Southern California around now — to some extent, the weather is “routine,” he said.
Still, temperatures climbed rapidly in the Los Angeles area beginning Friday, especially inland and in the desert. And because the rise came so suddenly following a temperate period, it may have posed an unusually high risk to Californians who hadn’t yet acclimated to the season’s hotter temperatures. Extreme heat can also create arid conditions begetting wildfires, though no reports of serious fires in California have emerged following July 4 fireworks displays. —Will Kubzansky
July 5: This year’s Fourth of July was the world’s hottest day on record, and that record will likely be broken again this summer. In Texas, the heat was nothing new: The last day El Paso recorded a high temperature under 100 degrees was June 15. Since then, every day has gotten up to the triple digits — with the heat reaching 108 degrees on June 26 and 27.
In other words, it’s still really, really hot in Texas as a heat dome remains firmly planted over the state. Some parts of Texas have seen a handful of cooler days — July 4 wasn’t quite as brutal in Houston, for instance, and San Antonio’s temperatures have largely fallen back into the ‘90s. But the southern part of the state is in what the San Antonio Express-News describes as a “rut”: Heat is giving way to marginally cooler temperatures but the weather is expected to get hotter and more humid again.
For older people or people who work outdoors, the sustained heat has proven especially deadly. The vast majority of Texas’s prisoners, meanwhile, are without air conditioning. —Will Kubzansky
The North Atlantic Ocean is in the middle of a startling heat wave that could have far-reaching repercussions.
The weeks-long marine heat wave broke records for the months of May and is expected to do the same in June. Sea surface temperatures around the U.K. and northern Europe are an astonishing 9 degrees Fahrenheit above average in places, The Washington Post reports.
“Totally unprecedented,” Richard Unsworth, a biosciences professor at the U.K.’s Swansea University, told CNN. It’s “way beyond the worst-case predictions for the changing climate of the region.” Scientists say the warming oceans could have significant consequences, from harming marine life to decreasing the sea’s capacity to absorb pollution.
Above-average heat has also hit the U.K. Temperatures are expected to hit 89 degrees Fahrenheit in southeast England over the weekend.
As a flotilla in the Atlantic searched for the missing Titan submersible, the prominent environmental writer Bill McKibben tweeted, “The truly terrifying news this week is not what happened deep beneath the sea, it’s what’s going on at the surface.” —Annie Xia
June 22: Texans will only get a brief reprieve from the most extreme highs of their heat wave before temperatures pick back up early next week. Notably, temperatures aren’t falling considerably at night, making the heat even more dangerous. North Texas will see the mercury rise up to 104 degrees through Thursday, with the small caveat that humidity will decline into a more comfortable range as the week goes on. In parts of Southwest Texas, the heat won’t let up at all: the high temperatures in Del Rio will hover between 107 and 110 through next Wednesday.
The Electric Reliability Council of Texas issued its first voluntary conservation notice of the heat wave this past Tuesday. While the utility was able to meet demand, it requested that all Texans, especially government agencies, reduce their electricity use.
Mexico is similarly seeing scorching temperatures, which have led to eight deaths already. And high heat in the Rio Grande Valley means that migrants who traverse the border in Southwest Texas could be left exposed to the same high heat, which can have deadly consequences. —Will Kubzansky
Week of June 19: Temperatures in the northern Indian states of Uttar Pradesh and Bihar, two of the most populous in the country, reached as high as 115 degrees Fahrenheit (46 degrees Celsius), CNN reports. The extreme heat triggered power cuts, leaving people without running water, fans, or air conditioners.
The Associated Press reports nearly 170 people had died as of June 20, overwhelming hospitals, morgues, and crematoria — although state officials dispute the connection to the heat wave. Nearly half of the deaths came from a single district, Ballia, in Uttar Pradesh; officials say they have opened an investigation into the cause, which they say could be linked to contaminated water. Members of opposition parties blame the state government and its chief minister, Yogi Adityanath, for not investing enough in medical facilities or warning residents about the heat wave ahead of time. —Neel Dhanesha
June 19: The numbers from Texas’ heat wave are already striking: Dallas tied a humidity record on Thursday, and tens of millions of Texans woke up Friday to heat advisories or warnings. Temperatures will approach — and possibly break — records in Austin early next week, with highs between 104 and 106 through Wednesday. In the area, the heat indices will be highest over the Rio Grande plains and coastal plains, according to the National Weather Service’s Austin/San Antonio office.
Houston, in the meantime, saw its first excessive heat warning since 2016, with heat indices potentially breaking 115 degrees Friday and Saturday. Texas’ grid has held up (so far) — though the Electric Reliability Council of Texas has projected that next week will shatter the record levels of electricity demand that were just set this week, thanks to the number of air conditioners expected to be on full blast. —Will Kubzansky
June 14: Triple-digit heat has arrived early in Texas. Large parts of central and southeast Texas saw the heat index climb into the 100s Wednesday, topping out in McAllen at a searing 118. The heat wave is expected to spread and last through the week, hitting San Antonio, Dallas, Houston, and Austin, where it will feel like 112 degrees Thursday.
But while meteorologists watch for record heat and humidity, others will keep their eye on the state’s isolated electricity grid. Its operators, the Electric Reliability Council of Texas, warned of record-breaking electricity use Friday, an ominous signal for a state that has struggled with deadly blackouts in recent years. But this is just Texas’s first test of the summer: The grid operators noted that the record-breaking demand will likely be surpassed later in the summer. —Will Kubzansky
June 7-11: As skies over New York and Washington, D.C., turned orange from wildfire smoke, Puerto Rico and nearby Caribbean nations sweltered under a heat dome. The Heat Index, which takes into account both heat and humidity, went as high as 125 degrees in parts of Puerto Rico — a number that Jeff Berardelli, chief meteorologist at Tampa Bay’s WFLA-TV, said was astonishing. Temperature records broke across the island.
The Puerto Rican power grid still hasn’t recovered after Hurricane Maria hit the island in 2017, and over 100,000 Puerto Ricans reportedly lost power (though, as Pearl Marvell pointed out in Yale Climate Connections, the exact number cannot be verified because the island’s power company asked PowerOutage.us, which tracks outages, to stop collecting data on Puerto Rico until it can “replace their technology and provide more accurate data”). As I wrote in May, the combination of extreme heat and blackouts has the potential to be incredibly deadly, though no deaths were reported from this heat dome as of publication. —Neel Dhanesha
June 5: Large parts of China have seen record-breaking heat over the past month, one year after the worst heat wave and drought in decades hit the country. This year, Yunnan and Sichuan provinces saw temperatures exceed 40° C (104° F); according to CNN, heat in some parts of the country was so bad that pigs and rabbits died on farms and carp being raised in rice fields "burned to death" as water temperatures rose. Henan province had the opposite problem; extreme rain flooded wheat fields there, ruining crops in the country's largest wheat-growing region.
Meanwhile, a prolonged heat wave in Vietnam is keeping temperatures between 26 and 38 degrees Celsius (78.8 and 100.4° F), prompting officials to turn off street lights and ask citizens to cut down on their power consumption to avoid blackouts. VNExpress reports that many Vietnamese citizens who can't afford air conditioners are seeking respite in public spaces like libraries, buses, department stores, and cafes. —Neel Dhanesha
May 12: Some 12 million people in Washington and Oregon were under a heat advisory for four days starting May 12 as temperatures in the region topped out at more than 20 degrees above the normal high at that time of year, which should have been in the mid-60s.
"It’s harder for people in the Pacific Northwest to cool down when it’s 90 out than for people in, say, Phoenix or Las Vegas — cities that were constructed with heat in mind," wrote Heatmap Founding Staff Writer and Washington native Jeva Lange in her larger story about this heat wave. "Seattle, for example, is the second-least-air-conditioned metro area in the country (behind only “the coldest winter I ever spent was a summer in” San Francisco). Just over half of the homes in the area have a/c, and many of them are new buildings." —Neel Dhanesha and Jeva Lange
April: A large, deadly heat wave baked much of Asia for two weeks in April, Axios reported. Parts of India saw temperatures beyond 40°C (104°F), while temperatures in Thailand reached their highest levels ever, breaking past 45°C (113°F) for the first time in that country's history. Thirteen people died in Mumbai, and hundreds of people across the Asian continent were hospitalized. —Neel Dhanesha

The new climate politics are all about affordability.
During the August recess, while members of Congress were back home facing their constituents, climate and environmental groups went on the offensive, sending a blitz of ads targeting vulnerable Republicans in their districts. The message was specific, straightforward, and had nothing to do with the warming planet.
“Check your electric bill lately? Rep. Mark Amodei just voted for it to go up,” declared a billboard in Reno, Nevada, sponsored by the advocacy group Climate Power.
“They promised to bring down prices, but instead our congressman, Derrick Van Orden, just voted to make our monthly bills go up,” a YouTube ad told viewers in Wisconsin’s 3rd district. “It removes clean energy from the electric grid, creating a massive rate hike on electricity,” the voiceover says, while the words “VAN ORDEN’S PLAN: ELECTRICITY RATE HIKE” flash on screen. The ad, paid for by Climate Power, the League of Conservation Voters, and House Majority Forward, a progressive campaign group, was shown more than a million times from August 13 to 27, according to Google’s ad transparency center.
Both were part of a larger, $12 million campaign the groups launched over the recess in collaboration with organizations including EDF Action and Climate Emergency Advocates. Similar billboards and digital ads targeted Republicans in more than a dozen other districts in Arizona, California, Colorado, Iowa, Michigan, New York, Ohio, Pennsylvania, and Texas. There were also TV spots, partnerships with Instagram influencers, bus stop posters, and in-person rallies outside district offices — all blaming Republicans in Congress for the increasing cost of food, healthcare, and energy.

As others have observed, including Heatmap’s Matthew Zeitlin back in March, rising utility rates and the broader cost of living crisis are becoming a political liability for Republicans and President Trump. Clean energy advocates are attempting to capitalize on that, trying to get Americans to connect the dots between their mounting electricity bills and their representatives in Congress who voted to cut support for renewable energy.
Some of this is run-of-the-mill politicking, but it’s not only that. It also represents a strategic shift in how the climate movement talks about the energy transition.
It’s not new for green groups to make the argument that renewable energy can save people money. Relying on “free” wind and sun rather than fuels that are subject to price volatility has always been part of the sell, and the plummeting cost of solar panels and wind turbines have only made that pitch more compelling.
But it is new for the affordability argument to come first — above job creation, economic development, reducing pollution, and, of course, tackling climate change.
For most of the past four years, the climate movement has gone all in on trying to build an association in the American mind between the transition to clean energy and jobs. “When I think of climate change, I think of jobs,” then-candidate Joe Biden said during one of his 2020 campaign speeches.
It made sense at the time, Daniel Aldana Cohen, a sociologist at the University of California, Berkeley, told me. Just two years earlier, the Sunrise Movement had emerged as a political force with a headline-grabbing rally in Nancy Pelosi’s office demanding “green jobs for all.” The group was joined by then-newly elected Representative Alexandria Ocasio-Cortez, who soon introduced her framework for a Green New Deal that would offer a “just transition” for fossil fuel workers, ensuring them a place in the new clean energy economy.
The fossil fuel industry had seeded divisions between labor and environmental groups for decades by arguing that regulations kill jobs, and Democrats would have to upend that narrative if they wanted to make progress on climate. But the rationale was also more pressing: Unemployment was skyrocketing due to the COVID-19 pandemic, and whoever won the presidency would be responsible for rebuilding the U.S. workforce.
Fast forward to the end of Biden’s first year in office, however, and the unemployment rate had snapped back to pre-pandemic levels. Meanwhile, inflation was rising fast. Even though the Democrats managed to name their climate bill the “Inflation Reduction Act,” the administration and the climate movement continued talking about it in terms of jobs, jobs, jobs.
Cohen co-directs the Climate and Community Institute, a progressive think-tank founded in 2020, and admitted that “from the very start, we would just model every policy with jobs numbers,” partly because modeling the effects of policies on cost of living was a lot more complicated. Now he sees two issues with that approach. For one, it was always going to take time for new manufacturing jobs to materialize — much longer than an election cycle. For another, when unemployment is low, “everybody experiences inflation, but extremely few people experience a good new green job,” Cohen said.
During a recent panel hosted by the Institute for Policy Studies, Ben Beachy, who was a special assistant to Biden for climate policy, expressed some regret about the jobs push. “It wasn't addressing one of the biggest economic concerns of most people at that point, which was the rent is too damn high,” he said. But Beachy also defended the strategy, noting that all of the policies addressing cost of living in Biden’s big climate bill, like money for housing, public transit, and childcare, had been stripped out to appease West Virginia Democrat Joe Manchin. “So we were left without a strong policy leg to stand on to say, this is going to lower your costs.”
When the moderator asked what message Beachy thinks climate candidates should run on today, Beachy replied, “affordability, affordability, affordability.”
Jesse Lee, a senior advisor at Climate Power who also worked as a senior communications advisor in the Biden White House, echoed Beachy’s account of what went wrong post-IRA. The cost of living crisis makes it almost impossible to talk about anything else now, he told me. “If you don't start off talking about that, you’ve lost people before you’ve even begun,” he said.
Average U.S. electricity rates jumped 10% in just the year from 2021 to 2022, and have continued to rise faster than inflation. All evidence suggests the trend will continue. Utilities have already requested or received approval for approximately $29 billion in rate increases this year, according to the nonprofit PowerLines, compared to roughly $12 billion by this time last year. And these increases likely don’t reflect the expected costs associated with ending tax credits for wind and solar, hobbling wind and solar development, and keeping aging, expensive coal plants online.
In mid-July, Climate Power issued a strategy document advising state and local elected officials how to talk about clean energy based on the group’s polling. A post-election poll found that “more than half of Americans (51%) say the main goal of US energy policies should be to lower energy prices,” and that 85% “believe policymakers should do more to lower energy costs.” A more recent poll found that telling voters that “cutting clean energy means America produces less energy overall, and that means families will pay even more to keep the lights on,” was the most persuasive among a variety of arguments for clean energy.
This tracks with our own Heatmap Pro opinion polling, which found that the top perceived benefit of renewables in the U.S. is “lower utility bills” — though while 75% of Democrats believe that argument, only 56% of Republicans do. An affordability frame also aligns with academic research on clean energy communication strategies, which has found that emphasizing cost savings is a more effective and enduring message than job creation, economic development, or climate change mitigation.
The pivot to affordability isn’t just apparent in district-level campaigns to hold Republicans accountable. Almost every press release I’ve received from the climate group Evergreen Action this month has mentioned “soaring power bills” or “Trump’s energy price hike” in reference to various actions the administration has taken to hamstring renewables. Even clean energy groups, which at first attempted to co-opt Trump’s “energy dominance” frame, can no longer parrot it with a straight face. After Trump issued a stop work order on Orsted’s offshore Revolution Wind project, which is 80% built, the American Clean Power Association accused the administration of “raising alarms about rising energy prices while blocking new supply from reaching the grid.”
Several people I spoke to for this story pointed to the example of Mikie Sherill, the Democrat running for governor in New Jersey, who last week vowed to freeze utility rates for a year if elected. She immediately followed that statement with a promise to “massively expand cheaper, cleaner power generation,” including solar and batteries.
Dan Crawford, the senior vice president of Echo Communications Advisors, a climate-focused strategy firm, declared in a recent newsletter that Democrats should “become the party of cheap electricity.” He mused that we may be at an inflection point “where the old politics of clean-vs.-polluting makes way for a new debate of cheap-vs.-expensive.”
Debate is probably too tame a term — the claim to affordability is becoming a full-on messaging war. Last week, President Trump took to social media to declare that states that get power from wind and solar “are seeing RECORD BREAKING INCREASES IN ELECTRICITY AND ENERGY COSTS,” — a claim that has no basis in reality. The Trump administration is leaning heavily on affordability arguments to justify keeping coal plants open. In defense of canceling Revolution Wind, Interior Secretary Doug Burgum told Fox News that “this is part of our drive to make sure we’ve got affordable, reliable energy for every American … These are the highest electric prices in the country coming off of these projects.” On Thursday, Energy Secretary Chris Wright posted a news story about his agency rescinding a loan for an offshore wind transmission project, writing that “taxpayers will no longer foot the bill for projects that raise electricity prices and ultimately don't work.”
Clean energy proponents aren’t just going up against Trump — the fossil fuel industry has leaned on affordability as a rhetorical strategy for a long time, Joshua Lappen, a postdoctoral fellow at the University of Notre Dame studying the energy transition, told me. Lappen, who lives in California, said cost has been at the forefront of conflicts over climate policy in the state for a while. At the moment, it’s driving a fight over oil refinery closures that threaten to drive up gas prices even more. “I took a trip over the weekend and drove through the Central Valley,” Lappen told me, “and there are placards zip-tied to every gas pump at Chevron stations that are highlighting that state climate policy is increasing the cost of gas.”
I asked Lee, of Climate Power, how the climate movement could make a convincing case when clean energy has become so politically charged. He’s not worried about that right now. “I don’t think we necessarily need to win a debate about what’s cheaper,” he said. “All we have to do is say, Hey, we're in favor of more energy, including wind and solar, and it's nuts, nuts to be taking wind and solar and batteries off the table when we have an energy crisis and when utility rates have gone up 10%.”
That may work for now, at least at the national level. Americans tend to blame whoever is in office for the economic pains of the moment, even though presidents have little influence on prices at the pump and it can take years for policy changes to make their way into utility rates.
But there’s a difference between defensively blaming rising energy costs on the administration’s efforts to block renewables, and making a positive case for the energy transition on the same grounds. While there is an argument for the latter, it’s a lot harder to convey.
The factors pushing up energy prices, such as necessary grid modernization and disaster-related costs, likely aren’t going away, whether or not we build offshore wind farms. Meanwhile, the savings that large-scale wind and solar projects offer won’t be experienced as a reduction in rates — they won’t be experienced at all because they’re measured against a counterfactual world where renewables don’t get built. That’s a lot trickier to communicate in a pithy campaign. People may end up blaming the wind farms either way.
This dilemma is a hallmark of the so-called “mid-transition,” Lappen told me. The term was coined by his advisor, the energy engineer and sociologist Emily Grubert, and Sara Hastings-Simon, a public policy professor at the University of Calgary. The two argue that the mid-transition is a period where fossil fuel systems persist alongside the growing clean energy sector.
“Comparisons of the new system to the old system are likely to rest on experience of a world less affected by climate change, such that concerns about lower reliability, higher costs, and other challenges might be perceived as inherent to zero-carbon systems, versus energy systems facing consequences of climate change and long-term underinvestment,” they write.
To Cohen, advocates need to go a lot further than rhetoric to link clean energy with affordability. “We need to rebuild the brand and then rebuild the investment priorities of climate action so that working class communities see and literally touch direct, tangible benefits in their life,” he said. He described a “green economic populism” with much more public investment in helping renters access green technologies that will lower their bills, for example, or in fixing up homes that have deferred maintenance so that they can eventually make energy efficiency improvements.
It’s not about abandoning industrial policy or research and development, Cohen told me, but rather about a shift in emphasis. He pointed to Sherill’s approach. “She's not just saying, oh, clean energy will automatically lower bills if you just unleash it. She's like, I'm going to assertively use the government to guarantee a price freeze, and then I’m going to backfill that with clean energy policies to bring down prices over time.”
To be fair, the IRA did contain policies that would have produced more tangible benefits. The $7 billion Solar for All program would have delivered the benefits of residential solar — i.e. energy bill savings — to low-income households all over the country. The remainder of the Greenhouse Gas Reduction Fund, of which Solar for All was a part, was set to make a range of other green home upgrades more accessible to the working class, and the Green and Resilient Retrofit Program would have done the same for low-income housing developments and senior living centers. Electric school bus grants and urban tree-planting programs would have brought cleaner, cooler air to communities.
These were big, ambitious programs that were never going to produce results in the span of two years, and now the Trump administration has made every effort to ensure they never do. Whether they would have paid political dividends eventually, we’ll never know. But a successful energy transition may depend on giving it another shot.
On fusion’s big fundraise, nuclear fears, and geothermal’s generations uniting
Current conditions: New Orleans is expecting light rain with temperatures climbing near 90 degrees Fahrenheit as the city marks the 20th anniversary of Hurricane Katrina • Torrential rains could dump anywhere from 8 to 12 inches on the Mississippi Valley and the Ozarks • Japan is sweltering in temperatures as high as 104 degrees.
The Environmental Protection Agency is preparing to propose a new Clean Water Act rule that would eliminate federal protections for many U.S. waterways, according to an internal presentation leaked to E&E News. If finalized, the rule would establish a two-part test to determine whether a wetland received federal regulations: It would need to contain surface water throughout the “wet season,” and it would need to be touching a river, stream, or other body of water that flows throughout the wet season. The new language would require fewer wetland permits, a slide from the presentation showed, according to reporter Miranda Willson. Two EPA staffers briefed on the proposal confirmed the report.
The new rule follows the 2023 Supreme Court decision in Sackett v. EPA, which said that only waterways “with a ‘continuous surface connection’ to a ‘relatively permanent’ body of water” fell under the Clean Water Act’s protections, according to E&E News. What “relatively permanent” means, however, the court didn’t say, nor did Biden’s EPA. The two EPA staffers, who were granted anonymity to avoid retribution, “said they believed the proposal was not based in science and could worsen pollution if finalized,” Willson wrote.
Investors are hot on the Massachusetts Institute of Technology spinoff promising to make fusion energy a reality. Commonwealth Fusion Systems netted an eye-popping $863 million in its latest fundraising round. In a press release Thursday, the company said that its “oversubscribed round of capital is the largest amount raised among deep tech and energy companies since” its $1.8 billion financing deal in 2021. Commonwealth Fusion will use the funds to complete its demonstration project and further develop its proposed first power plant in Virginia. To date, the company said, it has raised close to $3 billion, “about one-third of the total capital invested in private fusion companies worldwide.” It’s a sign that investors recognize Commonwealth Fusion “is making fusion power a reality,” CEO Bob Mumgaard said.
The fusion industry has ballooned over the past six years. “It is finally, possibly, almost time” for the technology to arrive, Heatmap’s Katie Brigham wrote last year, noting: “For the ordinary optimist, fusion energy might invoke a cheerful Jetsons-style future of flying cars and interplanetary colonization. For the cynic, it’s a world-changing moment that’s perpetually 30 years away. But investors, nuclear engineers, and physicists see it as a technology edging ever closer to commercialization and a bipartisan pathway towards both energy security and decarbonization.”

A record 75 gigawatts of new generating capacity hooked up to the U.S. power grid last year, a 33% surge from the previous year, thanks to new federal regulations aimed at streamlining the process. That’s according to new data from the consultancy Wood Mackenzie published Thursday. The report found that the Federal Energy Regulatory Commission’s Order No. 2023, issued in July 2023, along with other reforms by independent system operators, have had a “considerable impact on processing interconnection agreements, by driving improvements through reducing speculative projects and clearing queue backlogs.” While connections increased, regional grid operators received 9% fewer new project entries and saw a 51% uptick in non-viable projects since 2022.
Solar and storage technologies made up 75% of all interconnection agreements in 2024, equaling about 58 gigawatts. Wood Mackenzie projected that the sectors will retain a similar market share in 2025. Natural gas saw an increase in interconnection requests since 2022, adding 121 gigawatts of capacity. New gas applications are already breaking annual records this year. But overall the number of gas projects that successfully hook up to the grid is down 25% since 2022.
Almost 200 people have left the Nuclear Regulatory Commission since President Donald Trump’s inauguration in January, according to new estimates published Thursday in the Financial Times. Of the 28 officials in senior leadership positions, nearly half are working in an “acting” capacity, and only three of the five NRC commissioner roles are filled. “It is an unprecedented situation with some senior leaders having been forced out and many others leaving for early retirement or worse, resignation,” Scott Morris, the former NRC deputy executive director of operations, who retired in May, told the newspaper. “This is really concerning for the staff and is one of the factors causing many key staff and leaders to leave the agency they love ... creating a huge brain drain of talent.”
The exodus comes as Trump is pressing the agency to dramatically overhaul and speed up its review and approval process for new reactors. Supporters of the president’s effort say the NRC has stymied the nuclear industry for decades, and a future buildout of new reactors requires clearing house. But skeptics of the burn-it-all-down approach warn that the atomic energy industry’s success in avoiding major accidents since the 1979 partial meltdown at Three Mile Island is owed to NRC oversight, and that the agency’s processes have actually protected nuclear developers by avoiding frivolous lawsuits and not-in-my-backyard types.
Geothermal giant Ormat has reigned over the global industry of harvesting energy from hot underground reservoirs for the past 60 years. Now a new generation of companies is promising to tap the Earth’s heat even in places without water by using fracking technology to drill much deeper, vastly expanding the potential for geothermal. And Ormat has placed a big bet on one. On Thursday, the company inked a strategic partnership with Houston-based Sage Geosystems. As part of the deal, Sage will build its first commercial power plant at an existing Ormat facility in Nevada or Utah, significantly speeding up the timeline for the debut generating station. Sage CEO Cindy Taff told me the plant could be online by next year. “Ormat’s chosen a winner,” Yakov Feygin, a researcher at the Center for Public Enterprise who co-authored a report on next-generation geothermal, told me.
A majority of U.S. voters are still unfamiliar with geothermal power, according to a new poll from Data for Progress I reported on this week. When exposed to details about how the technology works, however, support grows among voters across the political spectrum. Republicans in particular are supportive.

The Grammy- and Oscar-award winning New Orleans jazz and funk singer Jon Batiste released a new song to mark the 20th anniversary of Hurricane Katrina, the catastrophic storm that flooded his home city. Dubbed “Petrichor,” a word that describes the scent of earth after rain, the lyrics unfold like a haunting hymn over a driving beat. “Help me, Lord / They burning the planet down / No more second linin' in the street / They burning the planet down, Lord / Help me, Lord / No more plants for you to eat.” In an interview published in The Guardian, Batiste said the song was meant to be a statement. “You got to bring people together. People power is the way that you can change things in the world,” he said. “It’s a warning, set to a dance beat.”
How the Migratory Bird Treaty Act could become the administration’s ultimate weapon against wind farms.
The Trump administration has quietly opened the door to strictly enforcing a migratory bird protection law in a way that could cast a legal cloud over wind farms across the country.
As I’ve chronicled for Heatmap, the Interior Department over the past month expanded its ongoing investigation of the wind industry’s wildlife impacts to go after turbines for killing imperiled bald and golden eagles, sending voluminous records requests to developers. We’ve discussed here how avian conservation activists and even some former government wildlife staff are reporting spikes in golden eagle mortality in areas with operating wind projects. Whether these eagle deaths were allowable under the law – the Bald and Golden Eagle Protection Act – is going to wind up being a question for regulators and courts if Interior progresses further against specific facilities. Irrespective of what one thinks about the merits of wind energy, it’s extremely likely that a federal government already hostile to wind power will use the law to apply even more pressure on developers.
What’s received less attention than the eagles is that Trump’s team signaled it could go even further by using the Migratory Bird Treaty Act, a separate statute intended to support bird species flying south through the U.S. from Canada during typical seasonal migration periods. At the bottom of an Interior press release published in late July, the department admitted it was beginning a “careful review of avian mortality rates associated with the development of wind energy projects located in migratory flight paths,” and would determine whether migratory birds dying because of wind farms qualified as “‘incidental’ takings” – harm or death – under the Migratory Bird Treaty Act.
While not stated explicitly, what this means is that the department appears to be considering whether to redefine these deaths as intentional under the Migratory Bird Treaty Act, according to Ben Cowan, a lawyer with the law firm Troutman Pepper Locke.
I reached out to Cowan after the eagle investigation began because his law firm posted a bulletin warning that developers “holding active eagle permits” might want to prepare for “subpoenas that may be forthcoming.” During our chat earlier this month, he told me that the eagle probe is likely going to strain financing for projects even on private lands that wouldn’t require any other forms of federal sign-off: “Folks don’t want to operate if they feel there’s a significant risk they might take an eagle without authorization.”
Cowan then voiced increasing concern about the migratory bird effort, however, because the law on this matter could be a quite powerful – if legally questionable – weapon against wind development.
Unlike the Endangered Species Act or the eagle protection law, there is currently no program on the books for a wind project developer to even obtain a permit for incidental impacts to a migratory bird. Part of the reason for the absence of such a program is the usual federal bureaucratic struggle that comes with implementing a complex statute, with the added effect of the ping-pong of federal control; the Biden administration started a process for permitting “incidental” impacts, but it was scrapped in April by the Trump team. Most protection of migratory birds under the law today comes from voluntary measures conducted by private companies and nonprofits in consultation with the federal government.
Hypothetically, hurting a migratory bird should be legally permissible to the federal government. That’s because the administration loosened implementation of the law earlier this year with an Interior Department legal opinion that stated the agency would only go after harm that was “intentional” – a term of art under the statute.
This is precisely why Cowan is fretting about migratory birds, however. Asked why the wind industry hasn’t publicly voiced more anxiety about this potential move, he said industry insiders genuinely hope this is “bluster” because such a selective use of this law “would be so beyond the pale.”
“It’s basically saying the purpose of a wind farm is to kill migratory birds, which is very clearly not the case – it’s to generate renewable electricity,” Cowan told me, adding that any effort by the Interior Department would inevitably result in lawsuits. “I mean, look at what this interpretation would mean: To classify it as intentional take would say the purpose of operating a wind farm would be to kill a bird. It’s obviously not. But this seems to be a way this administration is contemplating using the MBTA to block the operation of wind farms.”
It’s worth acknowledging just how bonkers this notion is on first blush. Is the federal government actually going to decide that any operating wind farm could be illegal? That would put entire states’ power supplies – including GOP-heavy states like Iowa – in total jeopardy. Not to mention it would be harmful overall to take operating capacity offline in any fashion at a moment when energy demand is spiking because of data centers and artificial intelligence. Even I, someone who has broken quite a few eye-popping stories about Trump’s war on renewables, struggle to process the idea of the government truly going there on the MBTA.
And yet, a door to this activity is now open, like a cleaver hanging over the industry’s head.
I asked the Interior Department to clarify its timeline for the MBTA review. It declined to comment on the matter. I would note that in mid-August, the Trump administration began maintenance on a federal dashboard for tracking regulations such as these and hasn’t updated it since. So we’ll have to wait for nothing less than their word to know what direction this is going in.
