This summer was hot. It was wet. It was deadly. For most of us, it was a preview of the rest of our lives.
So here we are: Another summer in the books.
After Labor Day, whites go back in the closet; kids go back to school. Astronomically speaking, there are still technically 20 days left of summer, and climatologically speaking, we may have even longer to go than that — summers are getting longer as autumns contract. But culturally, anyway, we’re now headed into fall, an incongruous transition epitomized by the bastardized existence of the iced pumpkin spice latte. You know you’re living in the age of climate change when ...
It’s a good time, though, for taking stock. An astonishing 96% of Americans have faced at least one extreme weather alert from the National Weather Service since May 1, the Union of Concerned Scientists’ Danger Season tracker reports. Further, only seven counties out of 3,224 in the whole country and its territories had no heat, flood, fire, or storm warnings between May 1 and August 29 of this year, according to additional numbers supplied to Heatmap by the UCS — including, surprisingly, San Fransisco County in California, home of what has been called the single-most economically vulnerable major city to climate change in the U.S.
These were the others that dodged extreme weather alerts: Aleutians East Borough (Alaska); Aleutians West Census Area (Alaska); Ketchikan Gateway Borough (Alaska); Kodiak Island Borough (Alaska); and Norton City (Virginia). Together, they have a population of around 39,500 — just a fraction of San Francisco County’s 815,200.
But while San Francisco, some islands and bays in remote regions of Alaska, and a sliver of Virginia got lucky (this time and so far), it was a bad summer to be in Arizona, where there were more NWS extreme weather alerts issued than in any other state. Coconino County, home of the capital of Flagstaff, saw 146 alerts this summer due to a parade of heat, flood, and fire threats, followed closely by Mohave County, in the state’s northwesternmost corner, with a total of 145. New Mexico was right on Arizona’s tail with five counties in the top 10:
When it came to heat alerts specifically, Texas and Puerto Rico dominated the top of the list. In fact, Louisiana’s Sabine Parish was the highest-ranked non-Texan or Puerto Rican county for heat alerts, clocking in way down at #96.
The most flood alerts were experienced by California’s Inyo County, the home of Death Valley, which might be surprising until you remember how little rain it takes to trigger a disaster in the desert. Washington’s Yakima, Kittitas, and Skamania counties lead the list for fire weather alerts; and South Carolina’s Georgetown, Colleton, and Charleston counties lead for storm alerts. (The data was collected just before the brunt of Hurricane Idalia swept through northern Florida, Georgia, and the Carolinas). California’s Los Angeles County, the most populous in the country, faced a total of 80 extreme weather alerts this summer; the average for all counties was around 44.
The UCS Danger Season data (which will continue to be collected here through October) did not account for air quality warnings, which were the main story of the early summer in the U.S. — at times, more than a third of Americans faced degraded AQI due to smoke billowing south from the Canadian wildfires (which are themselves record-breaking). June 7 was the worst day for wildfire smoke exposure in American history “by far,” my colleague Robinson Meyer reported, and it happened not on the West Coast, where fires are routine, but in New York City, Philadelphia, Washington, D.C., and Toronto.
The next month, July, was the hottest month on Earth in probably 120,000 years (so you have that bragging right on about 4,000 or so generations of your ancestors). Some 40,000 different locations around the world recorded their hottest days ever in 2023, with nearly 20,000 of those in the United States, according to NOAA’s records. Though we didn’t break the global heat record this year (Death Valley only reached 128 degrees Fahrenheit, short of the 130 it needed to beat), the planet recorded its warmest day ever a few different times. Meanwhile, Vermont saw catastrophic summer flooding.
Then, in August, a grass fire fueled by hurricane winds ripped through Maui. Even three weeks later, we still don’t know how many people were killed. Undoubtedly, though, it is the deadliest wildfire in modern U.S. history — and all the more shocking for the fact that it burned through a former wetland, a grim testament to the effects of colonialism. America might not be through reckoning with massive fires, either; the peak of fire season is known as “Snaptember” among hot shot crews for a reason.
And summer wasn’t through with us yet. Hilary became the first tropical storm to hit Southern California in 84 years, and while the damage wasn’t too bad, the Los Angeles Times credits the urgency of the early warnings for saving lives. Subsequently, Hurricane Idalia became the first hurricane to make U.S. landfall in what is predicted to be an “above normal” season, strengthening from a Category 1 to a Category 4 storm in 24 hours thanks to record-warm waters in the Gulf of Mexico. Reports of the damage are still trickling in, but it can’t be good news for insurers in Florida and the Southeast.
It is difficult to tie any one weather-related disaster to climate change, but as Michael Wehner, a senior staff scientist at the Lawrence Berkeley National Laboratory, once succinctly put it to Mother Jones: “It’s not: Climate change flooded my house. It’s: Climate change changed the chances of flooding my house.” So, let’s look at the chances.
A recent study found that the prime wildfire conditions in Canada this year, which caused the choking smoke on the East Coast, were “at least twice as likely to occur there as they would be in a world that humans hadn’t warmed by burning fossil fuels,” The New York Times reports. The July heat dome that baked the South was “at least five times more likely due to human-caused climate change,” an analysis by Climate Central and The Guardian found. The odds of Vermont’s supposedly once-a-century flooding happening within 12 years of another 100-year storm in the state, Hurricane Irene, was just 0.6 percent. The fires in Maui were caused by compounding climate problems, The Washington Post reports, such as higher average temperatures and more intense hurricanes — both of which also have links to emissions-fueled warming. And Hurricane Idalia’s rapid intensification is what we’d expect to see from human-fueled ocean warming, too. Then there’s El Niño, which plays a part in all this chaos as well; it’s why scientists expect next year to be an even bumpier ride for earthly life than this summer has been.
That might not be very heartening to hear but consider this: If you’re a resident of anywhere other than San Francisco and a few odd places like Alaska’s Bristol Bay Borough (population: 838), then this summer was your dry run. You’ve learned more than you ever expected you’d need to know about indoor air purification; you spent 90 minutes prepping for wildfire season; you’ve checked in on elderly neighbors; you’ve even brushed up on your gin rummy skills so you can stay off your phone when the power goes out during the next (or same?!) hurricane. Look at you go. You’re adaptable. Heck, even iced pumpkin spice lattes are starting to grow on you now.

Current conditions: The remnants of Tropical Storm Chantal will bring heavy rain and potential flash floods to the Carolinas, southeastern Virginia, and southern Delaware through Monday night • Two people are dead and 300 injured after Typhoon Danas hit Taiwan • Life-threatening rainfall is expected to last through Monday in Central Texas.

The flash floods in Central Texas are expected to become one of the deadliest such events in the past 100 years, with authorities updating the death toll to 82 people on Sunday night. Another 41 people are still missing after the storms, which began Thursday night and raised the Guadalupe River some 26 feet in less than an hour, providing little chance for holiday weekend campers and RVers to escape.
Although it’s far too soon to definitively attribute the disaster to climate change, a warmer atmosphere is capable of holding more moisture and producing heavy bursts of life-threatening rainfall. Disasters like the one in Texas are one of the “hardest things to predict that’s becoming worse faster than almost anything else in a warming climate, and it’s at a moment where we’re defunding the ability of meteorologists and emergency managers to coordinate,” Daniel Swain of the University of California Agriculture and Natural Resources told the Los Angeles Times. Meteorologists who spoke to Wired argued that the National Weather Service “accurately predicted the risk of flooding in Texas and could not have foreseen the extreme severity of the storm” ahead of the event, while The New York Times noted that staffing shortages at the agency following President Trump’s layoffs potentially resulted in “the loss of experienced people who would typically have helped communicate with local authorities in the hours after flash flood warnings were issued overnight.”
President Trump announced this weekend that his administration plans to send up to 15 letters on Monday to important trade partners detailing their tariff rates. Though Trump didn’t specify which countries would receive such letters or what the rates could be, he said the tariffs would go into effect on August 1 — an extension from the administration’s 90-day pause through July 9 — and range “from maybe 60% or 70% tariffs to 10% and 20% tariffs.” Treasury Secretary Scott Bessent added on CNN on Sunday that the administration would subsequently send an additional round of letters to 100 less significant trade partners, warning them that “if you don’t move things along” with trade negotiations, “then on August 1, you will boomerang back to your April 2 tariff level.” Trump’s proposed tariffs have already rattled industries as diverse as steel and aluminum, oil, plastics, agriculture, and bicycles, as we’ve covered extensively here at Heatmap. Trump’s weekend announcement also sent jitters through global markets on Monday morning.
President Trump’s gutting of the Inflation Reduction Act with the signing of the budget reconciliation bill last week will add an extra 7 billion tons of emissions to the atmosphere by 2030, a new analysis by Climate Brief has found. The rollback on renewable energy credits and policy means that “U.S. emissions are now set to drop to just 3% below current levels by 2030 — effectively flatlining — rather than falling 40% as required to hit the now-defunct [Paris Agreement] target,” Carbon Brief notes. As a result, the U.S. will be about 2 billion tons short of its emissions goal by 2030, adding an emissions equivalent of “roughly the annual output of Indonesia, the world’s sixth-largest emitter.”
To reach its conclusions, Carbon Brief utilized modeling by Princeton University’s REPEAT Project, which examined how the current obstacles facing U.S. wind and solar energy will impact U.S. emissions targets, as well as the likely slowdown in electric vehicle sales and energy efficiency upgrades due to the removal of subsidies. “Under this new set of U.S. policies, emissions are only expected to be 20% lower than 2005 levels by 2030,” Carbon Brief writes.
Engineering giant SKF announced late last week that it had set a new world record for tidal turbine reliability, with its systems in northern Scotland having operated continuously for over six years at 1.5 megawatts “without the need for unplanned or disruptive maintenance.” The news represents a significant milestone for the technology since “harsh conditions, high maintenance, and technical challenges” have traditionally made tidal systems difficult to implement in the real world, Interesting Engineering notes. The pilot program, MayGen, is operated by SAE Renewables and aims, as its next step, to begin deploying 3-megawatt powertrains for 30 turbines across Scotland, France, and Japan starting next year.
Satellites monitoring the Southern Ocean have detected for the first time a collapse and reversal of a major current in the Atlantic Meridional Overturning Circulation. “This is an unprecedented observation and a potential game-changer,” said physicist Marilena Oltmanns, the lead author of a paper on the finding, adding that the changes could “alter the Southern Ocean’s capacity to sequester heat and carbon.”
A breakthrough in satellite ocean observation technology enabled scientists to recognize that, since 2016, the Southern Ocean has become saltier, even as Antarctic sea ice has melted at a rate comparable to the loss of Greenland’s ice. The two factors have altered the Southern Ocean’s properties like “we’ve never seen before,” Antonio Turiel, a co-author of the study, explained. “While the world is debating the potential collapse of the AMOC in the North Atlantic, we’re seeing that the Southern Ocean is drastically changing, as sea ice coverage declines and the upper ocean is becoming saltier,” he went on. “This could have unprecedented global climate impacts.” Read more about the oceanic feedback loop and its potential global consequences at Science Daily, here.
The French public research university Sciences Po will open the Paris Climate School in September 2026, making it the first school in Europe to offer a “degree in humanities and social sciences dedicated to ecological transition.” The first cohort will comprise 100 master’s students in an English-language program. “Faced with the ecological emergency, it is essential to train a new generation of leaders who can think and act differently,” said Laurence Tubiana, the dean of the Paris Climate School.
A fifth of U.S. counties now restrict renewables development, according to exclusive data gathered by Heatmap Pro.
A solar farm 40 minutes south of Columbus, Ohio.
A grid-scale battery near the coast of Nassau County, Long Island.
A sprawling wind farm — capable of generating enough electricity to power 100,000 homes — at the northern edge of Nebraska.
These projects — and hundreds of others — will never get built in the United States. They were blocked and ultimately killed by a regulatory sea-change that has reshaped how local governments consider and approve energy projects. One by one, counties and municipalities across the country are passing laws that heavily curtail the construction of new renewable power plants.
These laws are slowing the energy transition and raising costs for utility ratepayers. And the problem is getting worse.
The development of new wind and solar power plants is now heavily restricted or outright banned in about one in five counties across the country, according to a new and extensive survey of public records and local ordinances conducted by Heatmap News.
“That’s a lot,” Nicholas Bagley, a professor at the University of Michigan Law School, told us. Bagley said the “rash of new land use restrictions” owes partly to the increasing politicization of renewable energy.
Across the country, separate rules restrict renewables construction in 605 counties. In some cases, the rules greatly constrain where renewables can be built, such as by requiring that wind turbines must be placed miles from homes, or that solar farms may not take up more than 1% of a county’s agricultural land. In hundreds of other cases, the rules simply forbid new wind or solar construction at all.
Even in the liberal Northeast, where climate concern is high and municipalities broadly control the land use process, the number of restrictions is rising. At least 59 townships and municipalities have curtailed or outright banned new wind and solar farms across the Northeast, according to Heatmap’s survey.
Even though America has built new wind and solar projects for decades, the number of counties restricting renewable development has nearly doubled since 2022.
When the various state, county, and municipality-level ordinances are combined, roughly 17% of the total land mass of the continental United States has been marked as off limits to renewables construction.
These figures have not been previously reported. Over the past 12 months, our energy intelligence platform Heatmap Pro has conducted what it believes to be the most comprehensive survey of county and municipality-level renewables restrictions in the United States. In part, that research included surveys of existing databases of local news and county laws, including those prepared by the Sabin Center for Climate Change Law at Columbia University.
But our research team has also called thousands of counties, many of whose laws were not in existing public databases, and we have updated our data in real time as counties passed ordinances and opposed projects progress (or not) through the zoning process. This data is normally available to companies and individuals who subscribe to Heatmap Pro. In this story, we are making a high-level summary of this data available to the public for the first time.
Restrictions have proliferated in all regions of the country.
Forty counties in Virginia alone now have an anti-renewable law on the books, effectively halting solar development in large portions of the state, even as the region experiences blistering electricity load growth.
These anti-solar laws have even begun to slow down energy development across the sunny Southwest. Counties in Nevada and Arizona have rejected new solar development in the same parts of the state that have already seen a high number of solar projects, our data show. Since President Trump took office in January, the effect of these local rules have become more acute — while solar developers could previously avoid the rules by proposing projects on federal land, a permitting slowdown at the Bureau of Land Management is now styming solar projects of all types in the region, as our colleague Jael Holzman has reported.
In the Northeast and on the West Coast, where Democrats control most state governments, towns and counties are still successfully fighting and cancelling dozens of new energy projects. Battery electricity storage systems, or BESS projects, now draw particular ire. The high-profile case of the battery fire in Moss Landing, California, in January has led to a surge of local opposition to BESS projects, our data shows. So far in 2025, residents have cited the Moss Landing case when fighting at least six different BESS projects nationwide.
That’s what happened with Jupiter Power, the battery project proposed in Nassau County, Long Island. The 275-megawatt project was first proposed in 2022 for the Town of Oyster Bay, New York. It would have replaced a petroleum terminal and improved the resilience of the local power grid.
But opposed residents began attending public meetings to agitate about perceived fire and environmental risks, and in spring 2024 successfully lobbied the town to pass a six-month moratorium on battery storage systems. The developer of the battery storage system, Jupiter Power, announced it would withdraw after the town passed two consecutive extensions to the moratorium and residents continued agitating for tighter restrictions.
That pattern — a town passes a temporary moratorium that it repeatedly extends — is how many projects now die in the United States.
The Nebraska wind project, North Fork Wind, was effectively shuttered when Knox County passed a permanent wind-energy ban. And the solar project south of Columbus, Ohio? It died when the Ohio Power Siting Board ruled that “that any benefits to the local community are outweighed by public opposition” to the project, which would have generated 70 megawatts, enough to power about 9,000 homes.
The developers of both of these projects are now waging lengthy and expensive legal appeals to save them; neither has won yet. Even in cases where the developer ultimately prevails against a local law, opposition can waste years and raise the final cost of a project by millions of dollars.
Our Heatmap Pro platform models opposition history alongside demographic, employment, voting, and exclusive polling data to quantify the risk a project will face in every county in the country, allowing developers to avoid places where they are likely to be unsuccessful and strategize for those where they have a chance.
Access to the full project- and county-level data and associated risk assessments is available via Heatmap Pro.
And more on the week’s biggest conflicts around renewable energy projects.
1. Jackson County, Kansas – A judge has rejected a Hail Mary lawsuit to kill a single solar farm over it benefiting from the Inflation Reduction Act, siding with arguments from a somewhat unexpected source — the Trump administration’s Justice Department — which argued that projects qualifying for tax credits do not require federal environmental reviews.
2. Portage County, Wisconsin – The largest solar project in the Badger State is now one step closer to construction after settling with environmentalists concerned about impacts to the Greater Prairie Chicken, an imperiled bird species beloved in wildlife conservation circles.
3. Imperial County, California – The board of directors for the agriculture-saturated Imperial Irrigation District in southern California has approved a resolution opposing solar projects on farmland.
4. New England – Offshore wind opponents are starting to win big in state negotiations with developers, as officials once committed to the energy sources delay final decisions on maintaining contracts.
5. Barren County, Kentucky – Remember the National Park fighting the solar farm? We may see a resolution to that conflict later this month.
6. Washington County, Arkansas – It seems that RES’ efforts to build a wind farm here are leading the county to face calls for a blanket moratorium.
7. Westchester County, New York – Yet another resort town in New York may be saying “no” to battery storage over fire risks.
