Riders in Chicago, Philadelphia, and the San Francisco Bay Area are staring down budget crises, with deep service cuts not far behind.

Three of the country’s largest public transportation systems are facing severe budget shortfalls that have left them near a breaking point. Transit riders in Chicago, Philadelphia, and the Bay Area of California could see severe service cuts as soon as next year if their representatives don’t secure funding to fill significant gaps in their operations budgets, the result of dwindling ridership and federal aid.
Should these lawmakers fail or fall short, they could kick off what transit advocates refer to as a “death spiral,” where higher fares and worse service leads to lower ridership, which leads to more cuts, etc., until there’s effectively no service left.
“I think that in a lot of cases, the public, legislators, governors are maybe not aware of just how high the stakes are right now,” David Weiskopf, the senior policy director for Climate Cabinet, a nonprofit that helps to elect climate-minded politicians, told me.
Public transit is a uniquely tricky, political issue, as it requires convincing elected officials from across a given state to address an issue that primarily affects people in one concentrated region — even if that region happens to be one of the main economic engines of the entire state economy. And yet transportation is the No. 1 way Americans contribute to climate change. While electric vehicles get a lot more attention as a climate solution, expanding public transit can also reduce emissions with the added benefits of minimizing the raw materials extraction and electricity demand that come along with EVs.
But that’s just a part of what Weiskopf is talking about in terms of the stakes. Millions of people rely on public transit to get themselves to work and their kids to school. Public transit also reduces local air pollution and traffic. Losing the services that already exist would surrender all of those benefits — worsening affordability and quality of life just as they have become top-tier political issues.
There’s a clear chain of events that led so many major transit systems to the brink of collapse this year. In the late 1990s, Congress eliminated federal funding for public transit operations in major cities, instead allocating all of its financial assistance to capital transit projects, such as new or improved infrastructure. Buses and metros began to rely more heavily on revenue from fares to cover operating expenses like staff and fuel. That became disastrous when the COVID-19 pandemic hit and cut ridership dramatically.
Congress passed a series of pandemic relief laws that provided substantial funding for transit operations, keeping them afloat to shuttle essential workers. But that money dried up, and in many places, ridership has remained stubbornly below pre-pandemic levels for reasons including the rise in remote work. Meanwhile, transit systems continued to age, and the cost of labor and materials rose.
State lawmakers have been slow to act, allowing their biggest cities’ transit systems to inch dangerously close to the edge of a fiscal cliff. In Illinois, the legislature has just a few days left in its session to find the money to prevent layoffs and service cuts across Chicago’s three transit systems next year. In California, the state is hammering out a stopgap loan to keep Bay Area operators funded through 2026, while betting the longer-term health of the system on a ballot measure next fall. The split Pennsylvania legislature is at a total impasse on the issue. Governor Josh Shapiro recently authorized transit agencies to dip into their capital budgets to prevent immediate service cuts, but there’s no longer-term solution in sight.
These three states are not entirely unique — almost every public transit system in the country is dealing with the same challenges. But they’re useful case studies to illustrate just how high the stakes are, and what kinds of solutions are on the table.
Prior to the pandemic, two of San Francisco’s regional rail systems — Bay Area Rapid Transit, or BART, and Cal Train — were covering upwards of 70% of their operating costs with fares, Sebastian Petty, the senior transportation policy director at the San Francisco Bay Area Planning and Urban Research Association, or SPUR, told me. In 2024, however, fare revenue was roughly half of what it was in 2019, covering just under a third of the cost of running the system, with the rest filled in by emergency federal assistance. “There’s no real, obvious path to financial sustainability that doesn't involve some longer source of sustained new public funding,” Petty said.
BART now projects that its COVID relief funding will be gone by spring of next year, after which it will face a deficit of $350 million to $400 million per year. The implications are catastrophic. The fixed costs of operating the system are so high that service cuts alone can’t make up the shortfall. BART estimates that even if it cut service by 90% — including closing at 9 p.m., cutting frequency from every 20 minutes to once an hour, shutting down two full train lines, laying off more than 1,000 workers — that would not be enough to close the gap.
The legislature decided on a regional sales tax as the best way to fund the system, but has left the final say in the matter up to voters. In September, lawmakers passed a bill that authorized a ballot measure in five Bay Area counties next year. Voters will be asked to approve a sales tax increase of half a cent — or a full cent, in the case of San Francisco — for a period of 14 years.
Regardless of whether the ballot measure is successful, however, the transit system still faces a fiscal cliff next year without some kind of bridge funding. A separate bill requires the state Department of Finance to propose a solution for short-term financial assistance for Bay Area transit agencies to bridge the roughly $750 million budget gap for the next year to prevent immediate service cuts. The department has a deadline of January 10, after which the legislature will have to vote on the proposal.
“To be frank, this is not a great position to be in,” Petty said. “People are really, really worried.” But he said this still seems like the best path forward given how large the scale of money needed is. “I say this as someone who’s worked in transit for a while,” Petty told me. “Transit seems to be in some degree of perpetual funding challenge, but this one really is different.”
Chicago’s Regional Transportation Authority, which governs the area’s three transit companies, says that it faces a $230 million budget shortfall next year, which could increase nearly fourfold in 2027 without new funding. The agency has warned that it will begin cutting paratransit service for people with disabilities as soon as April, which will expand to main line service and layoffs over the summer if the legislature can’t agree on a new revenue source this month.
Amy Rynell, executive director of the Active Transportation Alliance, a Chicago-based nonprofit, told me the uncertainty alone has hurt the transit operators’ ability to plan. “The agencies are having to spend a lot of time putting forth multiple budgets to figure out what to do in this moment,” she said. “That’s detracting from the ability to build for the future and develop new projects. People are having to look at keeping the doors open versus making transit better.”
Lawmakers in Illinois spent much of the first half of the year trying to nail down a deal, but they prioritized working on reforms to the regional transit system before figuring out how to fund it. On May 31, during the final hours of the regular legislative session, the state Senate passed a bill that would create several revenue raisers for public transit, such as a statewide $1.50 “Climate Impact Fee” on retail deliveries, a statewide electric vehicle charging fee, a real estate transfer tax, and a tax on rideshare services like Uber and Lyft. But lawmakers in the House claimed they didn’t have enough time to review the implications of such measures. An earlier idea to increase tolls died in the face of opposition from lawmakers representing the suburbs as well as labor groups.
The legislature has just three days left — October 28 through 30 — in a special veto session to reach an agreement on transit funding. Rynell was optimistic that it would get there. “It remains a priority of the House, Senate, and governor’s team,” she said. “People have put a lot of time and effort into getting a good package because the legislative leaders don’t want to be back in the same place in five or 10 years.”
For two years in a row, the Southeast Pennsylvania Transportation Authority, or SEPTA, has narrowly avoided a fiscal crisis with stopgap solutions from the governor’s office after the legislature failed to secure any transit funding. In November 2024, Governor Shapiro got approval from the Biden administration to transfer $153 million in federal capital highway funds to SEPTA, preventing immediate service cuts and postponing a 21% fare hike. But the agency still anticipated a $213 million gap, and said it would have to implement both the rate hike and service cuts this fall unless it secured additional funding.
The funding never came. The Pennsylvania legislature, paralyzed by a one-seat Democratic majority in the House and a Republican Senate, let a June 30 state budget deadline come and go. “Five of these funding bills, sort of different permutations, passed the State House that would have given sustainable revenue for transit,” Stephen Bronskill, the coalition manager at Transit Forward Philadelphia, told me. “All these bills were bipartisan. They failed in the State Senate.”
Weeks of uncertainty and chaos followed. In late August, SEPTA followed through with raising fares and began cutting service. Just two weeks later, however, a court sided with consumer rights advocates who argued that the cuts disproportionately impacted people of color and low-income riders, and ordered SEPTA to restore service.
During those two weeks, residents got a taste of what the future could hold: workers late to work, students late to class, overcrowded buses and trolleys, confusion about which routes were still operating. After the court order, SEPTA turned to a desperate measure — a request to use up to $394 million of state funds designated for capital expenditures on its operations, instead. The move would preserve full service for two years, but at the expense of infrastructure repairs and upgrades. Governor Shapiro approved the request.
“It’s a Band-Aid solution, and no new money for transit has been allocated,” Bronskill said. It’s also a particularly terrible time to deplete SEPTA’s capital budget, as its aging railcars are becoming dangerous to operate. There have been five fires on SEPTA railcars in 2025 alone. A recent report from the National Transportation Safety Board found that the Authority’s 1970s-era “silverliner” cars, which make up about 60% of the fleet, predate federal fire safety hazards and require either extensive retrofits or replacement.
The money will also only benefit transit systems in Philadelphia and Pittsburgh, Bronskill noted. “Every other transit agency across the state faces the same cliff of having to cut service in the face of the deficits. So we are continuing this fight.”
Pennsylvania lawmakers have proposed some of the same ideas that have been floated in Illinois to raise money for transit. They’ve also considered a car rental and lease tax, diverting funding from the state sales tax, taxing so-called “skill games” common at bars and convenience stores, and legalizing recreational marijuana.
To Justin Balik, the state program director for the climate advocacy group Evergreen Action, the challenge is not so much about coming up with revenue options as mustering “political will and urgency and prioritization.”
But more than anything, Pennsylvania suffers partisan politics and total paralysis due to its split legislature, which is now more than 100 days past the deadline to set even a basic state budget for next year. “I think once that is done, we all have our work cut out for us to tell the story in a compelling way of why the problem isn't solved and why we need faster action on this,” Balik said.
Evergreen is part of a new coalition of environmental and transit advocacy groups and think tanks called the Clean RIDES Network, which stands for Responsible Investments to Decrease Emissions in States, that’s trying to engender the political will for and prioritization of clean transportation solutions in statehouses around the country. The group is advocating for “a more holistic plan for transportation advocacy” that brings together ideas like avoiding highway expansions, improving transit access and efficiencies, and investing in vehicle electrification. Over 100 organizations are involved, including national groups like RMI, Sierra Club, and the NRDC, as well as state advocacy outfits like the Clean Air Council in Pennsylvania and Active Transportation Alliance in Illinois.
Advocates like Balik and Weiskopf, of Climate Cabinet, argued that it’s the right time to put transportation at the front and center of the climate fight. While there’s little state leaders can do to counter President Trump’s actions to weaken U.S. climate policy, public transit is one of the few areas they control. “This is a place that all of these lawmakers have the opportunity to do something meaningful and effective,” Weiskopf said, “even if it is just to prevent another thing from becoming much worse.”

We didn’t know days like this could happen. Then we learned how bad they really are.
When I woke up this morning in Chicago, the Air Quality Index was in the 300s, and I could barely see the top of the skyscraper across the street. The weather app on my phone featured a little image of a man wearing a World War I-style full-face gas mask. That’s fun, I thought. I didn’t know it could do that.
I went downstairs. Old photographs of the city were hanging in the hotel lobby — girls playing in bathing suits next to the lake — and I realized that the haze shrouding the old Lakeshore Drive condos was in fact haze, smoke, particulate matter, and not a lens artifact. It really used to be that smoky all the time, back before the Clean Air Act. Then I glanced up and saw that the haze out the window was far worse than the century-old pollution in the picture.
It’s significant, I think, that a mass smoke-out like this has now happened to the eastern U.S. for a second time. Second times matter. When exhaust from Canadian wildfires blanketed the Northeast and parts of the Midwest in June 2023, exposing more Americans to wildfire smoke than on any previous day in history, one could almost write it off as a freak occurrence. It was upsetting, sure, and reminiscent of California’s climate-addled amber skies. But didn’t wildfire smoke also descend on New England once in the 1780s? Even on a warmer planet, couldn’t this remain a once-in-a-century blip?
Twice in just over three years, though — that‘s more than a hiccup. That’s almost a trend. To get smoked out once may be regarded as a misfortune; for it to recur again, without any plan to respond, starts to look like carelessness. The federal government is doing roughly diddly squat about adaptation — President Trump can build a fan on the border and make Canada pay for it — but state and local governments across the eastern U.S. will now need to reckon with a new form of extreme weather. You grew up with snow days, but now we’ll have smoke days — and schools and sports leagues and concert venues will need rules about how to deal with them. When should games be canceled, tickets refunded? Is smoke more like a heat wave or a hurricane? Hotels and office buildings will need to review their ventilation policies and possibly upgrade their equipment; municipal emergency response plans will be revised and printed in triplicate.
All this will happen because the smoke has invaded a second time — and arguably a third, if you count last year’s minor episode — and that means it could come back again. For that reason, this event strikes me as a much bigger deal than what happened in 2023. The smoke is now a fact of life; institutions will need a policy about it. The tortious creep of litigation risk will enforce that outcome, even if no federal official enforces it.
So it goes. But to be clear, this new inconvenience is not what worries me most about today’s events. No, what frightens me instead is that today’s airborne toxic event is not something that was supposed to happen. Until a few years ago, we had not thought too hard about whether a major smoke exposure event like this could happen on the East Coast at all. It had not seemed possible.
For years, economists and climate scientists have simulated how global warming might affect the U.S. and global economies. They poured years of careful work into this modeling, and they simulated — with ever-increasing levels of statistical persnicketiness — what extreme heat and sea-level rise might do to agricultural yield, labor productivity, energy demand, heat mortality, and real estate values, among other potential sources of damage. This work was useful; it improved our practical understanding of coastal flooding, to name one example. It also helped calibrate U.S. regulatory policy, even if it never achieved the crowning heights of helping to set a national carbon tax.
Yet these careful models almost never accounted for mass smoke exposure days. Indeed, the kind of thing that happened this week — when heavy haze blows down from Canada and exposes more than 100 million people to hazardous air — was not countenanced by the simulations at all. Only in recent years did economists begin to study events like these, and only because mass exposure events like 2023’s happened first.
We’ve long known that the tiny shreds of particulate matter in wildfire smoke dance across the body’s barriers and penetrate its deep places, etching their way into lung, heart, and brain tissue. Inflammation follows. What makes days like today unique is the scale: Tens of millions of Americans inhaling wildfire smoke at the same time. As we’ve started studying this phenomenon, it’s become clear that the mortality effects of days like today, the deaths elevated above what you’d otherwise expect, can persist for years. That becomes extraordinarily expensive for society.
How costly? “When monetized,” a group of Stanford and Princeton economists wrote in Nature last year, in the first major study on the topic, “the climate-driven smoke deaths result in economic damages that exceed existing estimates of climate-driven damages from all other causes combined in the U.S.A.”
You read that right: The cost of climate-worsened wildfire smoke alone is larger than what earlier studies said every other estimated cost of climate change would be, combined.
To summarize, wildfire smoke did not appear in our economic simulations of climate change. As recently as a few years ago, we did not really know that days like today — or June 7, 2023; or September 15, 2020; or September 9, 2020 — could occur. Then they happened. And happened again. And then we studied them and discovered that, in fact, they may be more expensive for the U.S. economy than we once thought climate change itself would be.
That worries me. Now we know these smoke-out days can happen; now they are fast becoming a rare but predictable feature of summer life. But until recently they were unimaginable. What other ignominies, what other tail risks and airborne surprises, are lurking in the uncontrolled experiment we’re running on the biosphere? What else — unforecast, unmodeled, unstudied, unthought of — lies ahead? After 10 years of covering the climate system, I am not someone who lies sleepless fretting about atmospheric CO2. But I do wonder what else we don’t know enough about to ask.
“Microsoft, you can’t hide, we can see your dirty side!”
Protestors interrupted one of the final sessions of PNW Climate Week — a conference that brings together climate leaders across Washington, Oregon, and British Columbia — objecting to Microsoft’s rising carbon emissions from data centers and partnerships with oil and gas companies. The company’s Chief Sustainability Officer Melanie Nakagawa was having a one on one conversation with GeekWire climate reporter Lisa Stiffler at Seattle’s City Hall when protestors carrying signs reading “Microsoft’s AI pollutes” and other slogans began shouting from the audience.
I was there, having just moderated the prior panel on how to finance Washington’s clean energy ambitions. Early on there were some rumblings in the crowd from up front. “Climate leaders don’t build gas pipelines in Moses Lake,” was the first objection I heard clearly. It came shortly after Nakagawa kicked off the conversation by highlighting Microsoft’s partnership with sustainable aviation fuel startup Twelve, which recently opened its first commercial-scale SAF plant in Moses Lake, Washington. The tech giant has supported the project through a strategic investment from its Climate Innovation Fund, as well as an offtake agreement for the fuel that will help offset its emissions from employee travel.
Whether Microsoft is building a gas pipeline in this particular community I haven’t been able to determine, though it seems irrelevant to Twelve’s SAF facility, which doesn’t rely on natural gas. But it is true that Microsoft is one of the largest power consumers in Grant County, Washington, home to Moses Lake, where a natural gas pipeline operator is looking to expand its network to accommodate data center load growth.
Another audience interruption was more pointed. “How does signing a 20-year deal with Chevron help you reach your clean energy goals?,” one protestor asked, referring to Microsoft's recently announced power purchase agreement with Chevron for nearly 2.7 gigawatts of natural gas-fired power to supply a West Texas data center. The project represents one of the largest gas-powered artificial intelligence developments in the U.S., and Stiffler acknowledged that she had been planning to ask about it, herself.
Nakagawa answered the question. at least in part, saying “that project with Chevron is initially using natural gas and it’s a natural gas contract,” before emphasizing that the company has built “over 4.5 gigawatts of clean energy already today,” and remains committed to balancing speed-to-power with its clean energy goals. She added that, “with this deal in particular, we’re looking at a range of tools in our toolbox to ensure that we can continue to grow our power, but also do so in a way that is responsible and sustainable.” She stopped short, however, of making any commitments to transitioning the project to renewable energy over time.
The session became more chaotic from there. Another protestor stood up, shouting that “Microsoft is enabling genocide in Palestine.” Other activists joined in, while still other audience members shouted back. As Nakagawa recovered and resumed answering a question from Stiffler about Microsoft’s recent decision to pause its carbon removal purchases after years of dominating the nascent industry, protestors throughout the crowd began a chant of “Microsoft, you can’t hide, we can see your dirty side.” Security eventually shepherded many of them out.
Stiffler continued speaking with Nakawaga about the company’s clean energy efforts, touching on many of the protestors’ concerns as she asked about community opposition to data centers, the role of large corporations in the clean energy transition, and whether Microsoft can realistically achieve its goal of becoming carbon negative by 2030.
Nakawaga emphasized that the company must, “first and foremost, listen to where the communities are and what they are calling for.” Regarding the concerns she hears most often, she explained that “first has been transparency. Second has been around resource uses and what are we doing about those resource uses. We’re hearing about jobs and employment and investments in education, investments in housing.”
If this session was any indication, those concerns won’t go away anytime soon.
Heat kills more Americans than any other extreme weather event in the United States. But wildfire smoke — while not strictly “weather” — appears to kill even more. Current excess death estimates put American heat mortality at about 10,000 people per year, or possibly as high as 12,000. Recent studies on wildfire PM 2.5 exposure suggest a mortality of double that: 24,000 all-cause deaths every year.
Needless to say, wildfire smoke is definitely not something you want to inhale if you can avoid it. (And really, you should try to.) But for the 115 million Americans in the Great Lakes and Northeast regions of the country who’ve been exposed to hazardous air from the fires in Ontario and Minnesota this week, there’s a chance that the damage is already done. According to a wildfire smoke mortality estimation tool from Cornell University’s School of Public Health and the Northeast Regional Climate Center, the total mortality for this smoke event could already be as high as 424 people so far, including nearly 100 in Michigan and more than 50 in both New York and Wisconsin.
Alistair Hayden, an assistant professor of practice in Cornell’s Department of Public and Ecosystem Health, stressed to me that the tool is a “first draft,” and that his team is still working on getting it peer-reviewed. “We intend it as a hypothesis that people can test in the coming weeks or months to confirm our numbers,” Hayden told me. “I’m really hoping to be proven wrong.”
But Hayden also emphasized that while the West Coast might historically be where many smoke-related deaths have occurred, “this is the third out of four years [in the Northeast] that we’re having the smoke, so it seems like something we should be planning for,” he said. “It reminds me of that saying: ‘Fool me once, shame on you. Fool me twice, shame on me.’”
Admittedly, the smoke this week is a bit of a freak occurrence. A cooler-than-average sea surface pattern across the North Pacific, known as a negative phase of the Pacific Decadal Oscillation, helped produce weak low-pressure areas in the northwestern part of the United States, which in turn allowed for heat domes to develop across the Southwest and Plains. After one did just that earlier this month, the hot, high-pressure dome then shifted north, where it developed “dryness across Canada, followed by the lightning-producing thunderstorms,” Chad Merrill, a senior meteorologist at AccuWeather, told me. Then, boom: widespread fires.
“It is very unusual to have a combination of an El Niño and a negative phase of the Pacific Decadal Oscillation,” Merrill went on. “That’s one of the unusual factors this year, which contributed to the heat dome being farther north in that particular position.” The heat dome and jet stream then worked together to direct the thick smoke down into some of the most populous regions of Canada and the U.S.
That’s what makes this particular smoke event so bad. Were the smoke blowing over remote regions of Canada, as it would under more usual conditions, “then the big cities and the Great Lakes wouldn’t experience the smoke; it would have gone north toward the Hudson Bay and then Greenland,” Merrill said. In fact, the Canadian fire season is tracking below average overall; it’s the meteorological conditions that made this week’s smoke events, as one outlet put it, “the perfect storm.”
Wildfire smoke in the region is not historically anomalous, however. A 1903 article in The New York Times describes a “yellow day” similar to smoky events in 1894, 1881, and earlier. But large-scale burns in Canada’s dense, remote boreal, which produce more smoke, are increasing. Though it’s difficult to attribute any one wildfire directly to climate change because of the complex nature of such events, we do know that fire weather is becoming more common with the warming of the atmosphere from greenhouse gas emissions. As modeled by Zeke Hausfather in the Friday edition of his newsletter The Climate Brink, “hotter, drier seasons burn the most” in Canada — and “recent years cluster there” as the country has outpaced the global average in warming.
But as Hausfather also writes, “While overall area burned is the climate-linked trend, who breathes the smoke on a given week in July is mostly driven by the weather.” This is similar to the way that, though it may be a quiet year in the Atlantic, it only takes one hurricane making landfall in the right (or wrong) spot for the season to be remembered as catastrophic.
On the other hand, as foolish as it might be for the Central Plains and East Coast to still believe smoke is the exclusive domain of Westerners, it is also a mistake to assume smoke only comes from without. As I reported earlier this year, the Eastern half of the country has seen a 10-fold jump in the frequency of large burns over the last 40 years. Nowhere is safe from the smoke.
Planning and preparation, then, should be paramount. But as Grist learned last month, there are no established Air Quality Index numbers that would trigger the postponement, relocation, or cancellation of, say, a FIFA World Cup game, including the final, which is set to be played in New Jersey on Sunday. White House officials are reportedly meeting with FIFA’s president on Friday to discuss contingencies, given the unhealthy air quality in the region.
Which brings us back to Hayden’s modeling. He offered a note of optimism in that research by Stanford’s Sam Heft-Neal and his colleagues indicates that emergency room visits do not rise in tandem with increasing wildfire smoke. “As smoke gets bad, the health impacts get bigger. But then as smoke gets worse and worse, the amount of health impacts actually goes down, measured for emergency room visits,” Hayden said. “The idea is that people modify their behavior in higher smoke” — say, by staying indoors, wearing masks, or canceling outdoor events.
It’s time to treat smoke as an East Coast phenomenon, in other words. Doing so will save lives. “Will [smoke events] become more frequent in the future? Most likely we will see a recurrence,” Merrill, the meteorologist, told me. “How often they happen is yet to be determined.”
