Don’t let the political process intimidate you.
Driving less has a lot of benefits. You’ll be healthier than your vehicle-bound peers, about a third of whom don’t walk for more than 10 minutes a week. You’ll cut carbon dioxide, nitrous oxide, and methane emissions. In the process, you’ll probably realize how awful America’s public and active transportation infrastructure is — and may want to do something about it.
The same goes for just about any action you’ll find in Heatmap’s guide to decarbonizing your life. Should it be easier to get a permit to install rooftop solar panels? For sure. Should there be more public chargers to support EV adoption in your community? Without a doubt.
It can be especially overwhelming to think about getting involved in your local political processes when it comes to mobility because the cards are stacked so heavily in drivers’ favor. But it’s far from impossible. Here’s Heatmap’s guide to advocating for better transportation options and infrastructure in your community.
This might be the hardest step of all. To take transportation as an example, most American cities and towns were literally constructed to get drivers from point A to point B as fast as possible — meaning that their design is often actively hostile to anyone who wants to walk, bike, or take mass transit instead. If you put your mind to it, you could probably devise a dozen ways to make your immediate neighborhood friendlier to carless commuters.
Transportation for America’s transit advocate guide has several suggested starting places, including advocating for additional late-night service on a particular bus route, improving access to transit stations or stops (known as first- or last-mile connectivity), and pushing for shuttle services to connect riders with jobs. Petitioning for something like a bike lane, new sidewalk, safer intersections, or a missing crosswalk is another good place to start.
“Focus on one individual project,” Alexa Sledge, the communications director at Transportation Alternatives, a New York City nonprofit promoting non-polluting, safe, and quiet travel, told me. Being clear and focused on what you want — and, importantly, not getting overwhelmed or pulled in multiple directions — will help you achieve your goal. Strong Towns, a nonprofit that supports transportation advocates, calls this step the “humble observation:” identifying where people are struggling in your community and zeroing in on the smallest first possible step to help.
Here’s the excellent news: You aren’t in this fight alone.
Pretty much every major city and metropolitan region in the U.S. has its own transportation advocacy group these days, and you’re potentially just a Google search away from locating yours. (If you can’t find a transportation-specific group, look into local climate or pedestrian organizations, which frequently have overlapping objectives.)
It’s important to link up with others not just because they might already have identified priority projects in your area. Advocating for structural change requires, by definition, allies — and unfortunately, car-centricity is so dominant that transit advocates are often forced to prove the obvious community benefits of things like better bus routes or protected bike lanes.
If you don’t live in an area with an active transit group, nationwide organizations like Transportation for America and Strong Towns can connect with to get the tools, resources, training, and advice you need to start gathering allies.
How do I change a zoning law? Or weigh in on a renewable energy project near me?
Maybe you’re reading this guide because you’re interested in advocating climate-conscious zoning reform or want to weigh in on a wind farm nearby. There is a “profound diversity” of processes to do so from municipality to municipality, and no one-size-fits-all approach. That’s why it’s extra important to get involved with a local advocacy group; veteran organizers in your area can help you navigate the labyrinthine processes of your specific local government.
That said, here are a few things to keep your eyes peeled for:
There is an old urban planning joke about how traffic woes could be fixed by adding just one more lane. (They can’t be). Alas, this is also something of a federal policy; even though the 2021 Bipartisan Infrastructure Law set aside $36 billion to “transform our transportation system,” many states used their flexible funds for things like widening roads. Mass and active transit are often only an afterthought when it comes to funding: the Capital Investment Grants Program, one of the most significant federal programs for transit, is on the chopping block every budget-writing session, and programs like the Highway Trust Fund puts as little as 13% toward mass transit.
It’s our elected officials who make these decisions, though — and it’s their job to listen to their constituents. Here’s a handy page for determining the relevant senators and representatives to contact about federal funding for transit and active mobility policies; for local projects, you’ll want to reach out to your city council members, whose names and email addresses or phone numbers you should be able to find on your city website. And if you feel you’re getting brushed off by city staff when you reach out, focus on the smallest possible steps forward and be persistent (you can learn more strategies here).
The truth is, most people don’t go to their city council meetings. “When you really get down to the local level, there often aren’t as many people fighting, so you really can make a big difference,” Sledge said. Speaking up at hearings, town halls, public comment periods, or city council meetings can result in significant change and progress.
But let’s face it: Because most of us don’t have experience in local activism, telling someone to “go to a city council meeting” is much easier said than done. “The thing to remember is that your city council members work for you,” Sledge said. “They are elected members of your government, and you vote for them, and they are paid with taxpayer money. It’s part of their job to listen to you.”
Doug Gordon, the cohost of The War on Cars, a podcast about the fight against car culture, also suggested taking some of the pressure off yourself. “Don’t feel like you have to give the rousing patriotic speech in defense of the neighborhood bike lane,” he told me. “Just go and listen, and maybe if all that’s asked of you is to raise your hand when they ask how many people support this project, and that’s all you do, great.”
You don’t necessarily need to show up at a town council meeting or a representative’s office, either. Sledge suggested taking smaller steps like a phone call or email, or even just talking to people in your immediate community (for example, if you want a crosswalk outside your kid’s school, start by talking to the school board or other parents). When approaching someone like your city counselor, use language like: “This crosswalk is really important to me. How do I get this done?”
1. Depending on the project you’re pursuing, look up when your local transportation authority is inviting public comments ( here’s an example of what that page looks like in New York City). You can also search for when your state is holding public transportation hearings (here’s what Oklahoma’s looks like) and contact the relevant representatives to express your views. Most likely, though, you’ll be looking for your town’s public meeting schedule (here’s an example of San Jose’s) and seeking a special session related to transportation or a regular business meeting. Virtual hearings have also been common since the pandemic.
2. Research beforehand to learn how to comment publicly in your city or town. This may involve signing up on the town’s website or on a sign-in sheet when you arrive at the hearing.
3. In most cases, during the public comment portion of the city council meeting, you can address the council on any public issue (it does not have to be on the agenda). Again, check your city or town’s website to learn the specifics of procedures. Also, be aware of the time limit for your comments; generally, you’ll have about three minutes.
When you’re called on:
During your comment, you will probably see a timer somewhere in the room to help you track how long you have left to speak. The best comments are short and concise. Even if you’re frustrated with the process, be polite; remember that your comment can be seen and cited by anyone, including the media. Speak slowly. Here’s a guide for making an effective public comment from the National Resources Defense Council, with a sample script.
“If changing the system was easy,” writes Strong Towns, “we’d have done it long ago.” Many campaigns take years to come to fruition — being persistent and building a consensus, so advocates are working together toward the same cause, are two of the biggest lessons for success that Transportation for America stresses in their case studies.
It may take getting creative. Join the greater transportation advocacy community; listen to relevant podcasts, read related books, watch relevant YouTube videos, and learn from other campaigns. “You need a website, you need a public petition, and you need a T-shirt, because otherwise you’re just somebody with an opinion,” Rob Goodspeed, a founder of Trains Not Lanes, which successfully convinced Michigan’s Department of Transportation to drop highway expansion plans, told Streetsblog.
And when you do finally succeed? Celebrate. Promote it. Share your lessons with other organizers. Then identify a new project and begin again.

Half of all Americans are sweating under one right now.
Like a bomb cyclone, a polar vortex, or an atmospheric river, a heat dome is a meteorological phenomenon that feels, well, a little made up. I hadn’t heard the term before I found myself bottled beneath one in the Pacific Northwest in 2021, where I saw leaves and needles brown on living trees. Ultimately, some 1,400 people died from the extreme heat in British Columbia, Washington, and Oregon that summer weekend.
Since that disaster, there have been a number of other high-profile heat dome events in the United States, including this week, over the Midwest and now Eastern and Southeastern parts of the country. On Monday, roughly 150 million people — about half the nation’s population — faced extreme or major heat risks.
“I think the term ‘heat dome’ was used sparingly in the weather forecasting community from 10 to 30 years ago,” AccuWeather senior meteorologist Brett Anderson told me, speaking with 36 years as a forecaster under his belt. “But over the past 10 years, with global warming becoming much more focused in the public eye, we are seeing ‘heat dome’ being used much more frequently,” he went on. “I think it is a catchy term, and it gets the public’s attention.”
Catching the public’s attention is critical. Heat is the deadliest weather hazard in the U.S., killing more people annually than hurricanes, floods, tornadoes, or extreme cold. “There is a misunderstanding of the risk,” Ashley Ward, the director of the Heat Policy Innovation Hub at Duke University, told me. “A lot of people — particularly working age or younger people — don’t feel like they’re at risk when, in fact, they are.”
While it seems likely that the current heat dome won’t be as deadly as the one in 2021 — not least because the Midwest and Southeastern regions of the country have a much higher usage of air conditioning than the Pacific Northwest — the heat in the eastern half of the country is truly extraordinary. Tampa, Florida reached 100 degrees Fahrenheit on Sunday for the first time in its recorded history. Parts of the Midwest last week, where the heat dome formed before gradually moving eastward, hit a heat index of 128 degrees.
Worst of all, though, have been the accompanying record-breaking overnight temperatures, which Ward told me were the most lethal characteristics of a heat dome. “When there are both high daytime temperatures and persistently high overnight temperatures, those are the most dangerous of circumstances,” Ward said.
Although the widespread usage of the term “heat dome” may be relatively new, the phenomenon itself is not. The phrase describes an area of “unusually strong” high pressure situated in the upper atmosphere, which pockets abnormally warm air over a particular region, Anderson, the forecaster, told me. “These heat domes can be very expansive and can linger for days, and even a full week or longer,” he said.
Anderson added that while he hasn’t seen evidence of an increase in the number of heat domes due to climate change, “we may be seeing more extreme and longer-lasting heat domes” due to the warmer atmosphere. A heat dome in Europe this summer, which closed the Eiffel Tower, tipped temperatures over 115 degrees in parts of Spain, and killed an estimated 2,300 people, has been linked to anthropogenic warming. And research has borne out that the temperatures and duration reached in the 2021 Pacific Northwest heat dome would have been “virtually impossible without human-caused climate change.”
The link between climate change and heat domes is now strong enough to form the basis for a major legal case. Multnomah County, the Oregon municipality that includes Portland, filed a lawsuit in 2023 against 24 named defendants, including oil and gas companies ExxonMobil, Shell, and BP, seeking $50 million in damages and $1.5 billion in future damages for the defendants’ alleged role in the deaths from the 2021 heat dome.
“As we learned in this country when we took on Big Tobacco, this is not an easy step or one I take lightly, but I do believe it’s our best way to fight for our community and protect our future,” Multnomah County Chair Jessica Vega Pederson said in a statement at the time. The case is now in jeopardy following moves by the Trump administration to prevent states, counties, and cities from suing fossil fuel companies for climate damages. (The estate of a 65-year-old woman who died in the heat dome filed a similar wrongful death lawsuit in Seattle’s King County Superior Court against Big Oil.)
Given the likelihood of longer and hotter heat dome events, then, it becomes imperative to educate people about how to stay safe. As Ward mentioned, many people who are at risk of extreme heat might not even know it, such as those taking commonly prescribed medications for anxiety, depression, PTSD, diabetes, and high blood pressure, which interfere with the body’s ability to thermoregulate. “Let’s just say recently you started taking high blood pressure medicine,” Ward said. “Every summer prior, you never had a problem working in your garden or doing your lawn work. You might this year.”
Air conditioning, while life-saving, can also stop working for any number of reasons, from a worn out machine part to a widespread grid failure. Vulnerable community members may also face hurdles in accessing reliable AC. There’s a reason the majority of heat-related deaths happen indoors.
People who struggle to manage their energy costs should prioritize cooling a single space, such as a bedroom, and focus on maintaining a cool core temperature during overnight hours, when the body undergoes most of its recovery. Blotting yourself with a wet towel or washcloth and sitting in front of a fan can help during waking hours, as can visiting a traditional cooling center, or even a grocery store or movie theater.
Health providers also have a role to play, Ward stressed. “They know who has chronic underlying health conditions,” she said. “Normalize asking them about their situation with air conditioning. Normalize asking them, ‘Do you feel like you have a safe place to go that’s cool, that you can get out of this heat?’”
For the current heat dome, at least, the end is in sight: Incoming cool air from Canada will drop temperatures by 10 to 20 degrees in cities like Philadelphia and Washington, D.C., with lows potentially in the 30s by midweek in parts of New York. And while there are still hot days ahead for Florida and the rest of the Southeast, the cold front will reach the region by the end of the week.
But even if this ends up being the last heat dome of the summer, it certainly won’t be in our lifetimes. The heat dome has become inescapable.

In May, the Trump administration signaled its plans to gut Energy Star, the energy efficiency certification program administered by the Environmental Protection Agency. Energy Star is extremely popular — its brand is recognized by nearly 90% of Americans — and at a cost to the federal government of just $32 million per year, saves American households upward of $40 billion in energy costs per year as of 2024, for a total of more than $500 billion saved since its launch in 1992, by the EPA’s own estimate. Not only that, as one of Energy Star’s architects told Heatmap’s Jeva Lange back in May, more energy efficient appliances and buildings help reduce strain on the grid. “Think about the growing demands of data center computing and AI models,” RE Tech Advisors’ Deb Cloutier told Jeva. “We need to bring more energy onto the grid and make more space for it.”
That value has clearly resonated with lawmakers on the Hill. Legislators tasked with negotiating appropriations in both the Senate and the House of Representatives last week proposed fully funding Energy Star at $32 million for the next fiscal year. It’s unclear how the House’s decision to go into recess until September will affect the vote, but Ben Evans, the federal legislative director at the U.S. Green Building Council, said the bill is “a major step in the right direction demonstrating that ENERGY STAR has strong bipartisan support on Capitol Hill.”

The United States installed just under 11 gigawatts of solar panels in the first three months of this year, industry data show. In June alone, China installed nearly 15 gigawatts, PV Tech reported. And, in a detail that demonstrates just how many panels the People’s Republic has been deploying at home in recent years, that represented an 85% drop from the previous month and close to a 40% decline compared to June of last year.
The photovoltaic installation plunge followed Beijing’s rollout of two new policies that changed the renewables business in China. The first, called the 531 policy, undid guaranteed feed-in tariffs and required renewable projects to sell electricity on the spot market. That took effect on June 1. The other, called the 430 policy, took effect on May 1 and mandated that new distributed solar farms consume their own power first before allowing the sale of surplus electricity to the grid. As a result of the stalled installations, a top panel manufacturer warned the trade publication Opis that companies may need to raise prices by as much as 10%.
For years now, Fortescue, the world’s fourth-biggest producer of iron ore, has directed much of the earnings from its mines in northwest Australia and steel mills in China toward building out a global green hydrogen business. But changes to U.S. policy have taken a toll. Last week, Fortescue told investors it was canceling its green hydrogen project in Arizona, which had been set to come online next year. It’s also abandoning its plans for a green hydrogen plant on Australia’s northeastern coast, The Wall Street Journal reported.
“A shift in policy priorities away from green energy has changed the situation in the U.S.,” Gus Pichot, Fortescue’s chief executive of growth and energy, told analysts on a call. “The lack of certainty and a step back in green ambition has stopped the emerging green-energy markets, making it hard for previously feasible projects to proceed.” But green hydrogen isn’t dead everywhere. Just last week, the industrial gas firm Air Liquide made a final decision to invest in a 200-megawatt green hydrogen plant in the Netherlands.
The Trump administration put two high-ranking officials at the National Oceanic and Atmospheric Administration on administrative leave, CNN reported. The reasoning behind the move wasn’t clear, but both officials — Steve Volz, who leads NOAA’s satellites division, and Jeff Dillen, NOAA’s deputy general counsel — headed up the investigation into whether President Donald Trump violated NOAA’s scientific integrity policies during his so-called Sharpiegate scandal.
The incident from September 2019, during Trump’s first term, started when the president incorrectly listed Alabama among the states facing a threat from Hurricane Dorian. Throughout the following week, Trump defended the remark, insisting he had been right, and ultimately showed journalists a weather map that had been altered with a black Sharpie market to show the path of the storm striking Alabama. NOAA’s investigation into the incident concluded that Neil Jacobs, the former agency official who backed Trump at the time and is now nominated to serve as chief, succumbed to political pressure and violated scientific integrity rules.
In March, North Carolina’s Republican-controlled Senate passed a bill to repeal the state’s climate law and scrap the 2030 deadline by which the monopoly utility Duke Energy had to slash its planet-heating emissions by 70% compared to 2005 levels. Governor Josh Stein, a Democrat, vetoed the legislation. But on Tuesday, the GOP majorities in both chambers of the legislature plan to vote to override the veto.
Doing so and enacting the bill could cost North Carolina more than 50,000 jobs annually and cause tens of billions of dollars in lost investments, Canary Media’s Elizabeth Ouzts reported. That’s according to a new study from a consultancy commissioned by clean-energy advocates in the state. The analysis is based on data from the state-sanctioned consumer advocate, Public Staff.
For years, a mystery has puzzled scientists: Why did Neanderthal remains show levels of a nitrogen isotope only seen among carnivores like hyenas and wolves that eat more meat than a hominid could safely consume? New research finally points to an answer: Neanderthals were eating putrefying meat garnished with maggots, said Melanie Beasley, an anthropologist at Purdue University. “When you get the lean meat and the fatty maggot, you have a more complete nutrient that you’re consuming.”
Oregon’s Cram Fire was a warning — the Pacific Northwest is ready to ignite.
What could have been the country’s first designated megafire of 2025 spluttered to a quiet, unremarkable end this week. Even as national headlines warned over the weekend that central Oregon’s Cram Fire was approaching the 100,000-acre spread usually required to achieve that status, cooler, damper weather had already begun to move into the region. By the middle of the week, firefighters had managed to limit the Cram to 95,736 acres, and with mop-up operations well underway, crews began rotating out for rest or reassignment. The wildfire monitoring app Watch Duty issued what it said would be its final daily update on the Cram Fire on Thursday morning.
By this time in 2024, 10 megafires had already burned or ignited in the U.S., including the more-than-million-acre Smokehouse Creek fire in Texas last spring. While it may seem wrong to describe 2025 as a quieter fire season so far, given the catastrophic fires in the Los Angeles area at the start of the year, it is currently tracking below the 10-year average for acres burned at this point in the season. Even the Cram, a grassland fire that expanded rapidly due to the hot, dry conditions of central Oregon, was “not [an uncommon fire for] this time of year in the area,” Bill Queen, a public information officer with the Pacific Northwest Complex Incident Management Team 3, told me over email.
At the same time, the Cram Fire can also be read as a precursor. It was routine, maybe, but also large enough to require the deployment of nearly 900 fire personnel at a time when the National Wildland Fire Preparedness Level is set to 4, meaning national firefighting resources were already heavily committed when it broke out. (The preparedness scale, which describes how strapped federal resources are, goes up to 5.) Most ominous of all, though, is the forecast for the Pacific Northwest for “Dirty August” and “Snaptember,” historically the two worst months of the year in the region for wildfires.
National Interagency Coordination Center
“Right now, we’re in a little bit of a lull,” Jessica Neujahr, a public affairs officer with the Oregon Department of Forestry, acknowledged to me. “What comes with that is knowing that August and September will be difficult, so we’re now doing our best to make sure that our firefighters are taking advantage of having time to rest and get rejuvenated before the next big wave of fire comes through.”
That next big wave could happen any day. The National Interagency Fire Center’s fire potential outlook, last issued on July 1, describes “significant fire potential” for the Northwest that is “expected to remain above average areawide through September.” The reasons given include the fact that “nearly all areas” of Washington and Oregon are “abnormally dry or in drought status,” combined with a 40% to 60% probability of above-average temperatures through the start of the fall in both states. Moisture from the North American Monsoon, meanwhile, looks to be tracking “largely east of the Northwest.” At the same time, “live fuels in Oregon are green at mid to upper elevations but are drying rapidly across Washington.”
In other words, the components for a bad fire season are all there — the landscape just needs a spark. Lightning, in particular, has been top of mind for Oregon forecasters, given the tinderbox on the ground. A single storm system, such as one that rolled over southeast and east-central Oregon in June, can produce as many as 10,000 lightning strikes; over the course of just one night earlier this month, thunderstorms ignited 72 fires in two southwest Oregon counties. And the “kicker with lightning is that the fires don’t always pop up right away,” Neujahr explained. Instead, lightning strike fires can simmer for up to a week after a storm, evading the detection of firefighting crews until it’s too late. “When you have thousands of strikes in a concentrated area, it’s bound to stretch the local resources as far as they can go,” Neujahr said.
National Interagency Coordination Center
The National Interagency Fire Center has “low confidence … regarding the number of lightning ignitions” for the end of summer in the Northwest, in large part due to the incredible difficulty of forecasting convective storms. Additionally, the current neutral phase of the El Niño-Southern Oscillation means there is a “wide range of potential lightning activity” that adds extra uncertainty to any predictions. The NIFC’s higher confidence in its temperature and precipitation outlooks, in turn, “leads to a belief that the ratio of human to natural ignitions will remain high and at or above 2024 levels.” (An exploding transformer appears to have been the ignition source for the Cram Fire; approximately 88% of wildfires in the United States have human-caused origins, including arson.)
Periodic wildfires are a naturally occurring part of the Western ecosystem, and not all are attributable to climate change. But before 1995, the U.S. averaged fewer than one megafire per year; between 2005 and 2014, that average jumped to 9.8 such fires per year. Before 1970, there had been no documented megafires at all.
Above-average temperatures and drought conditions, which can make fires larger and burn hotter, are strongly associated with a warming atmosphere, however. Larger and hotter fires are also more dangerous. “Our biggest goal is always to put the fires out as fast as possible,” Neujahr told me. “There is a correlation: As fires get bigger, the cost of the fire grows, but so do the risks to the firefighters.”
In Oregon, anyway, the Cram Fire’s warning has registered. Shortly after the fire broke out, Oregon Governor Tina Kotek declared a statewide emergency with an eye toward the months ahead. “The summer is only getting hotter, drier, and more dangerous — we have to be prepared for worsening conditions,” she said in a statement at the time.
It’s improbable that there won’t be a megafire this season; the last time the U.S. had a year without a fire of 100,000 acres or more was in 2001. And if or when the megafire — or megafires — break out, all signs point to the “where” being Oregon or Washington, concentrating the area of potential destruction, exhausting local personnel, and straining federal resources. “When you have two states directly next to each other dealing with the same thing, it just makes it more difficult to get resources because of the conflicting timelines,” Neujahr said.
By October, at least, there should be relief: The national fire outlook describes “an increasing frequency of weather systems and precipitation” that should “signal an end of fire season” for the Northwest once fall arrives. But there are still a long 68 days left to go before then.
