A conversation with Manjula Martin about her new book The Last Fire Season.

When Manjula Martin was growing up in Northern California in the 1980s, wildfires weren’t something she thought about much. She knew about disaster — the magnitude 6.9 Loma Prieta earthquake of 1989, which killed 63 people and injured thousands, hit when she was a teenager — but fire, she thought, was just something that happened up in the mountains in the summer.
Things are different now. In 2017, Martin left the high prices of San Francisco for the redwoods of Sonoma County. The night of their housewarming party, a firestorm swept through Santa Rosa and Sonoma and Napa counties. The next year — 5 years ago this week — the Camp Fire, the deadliest and most destructive fire in the state’s history, destroyed the town of Paradise and killed 85 people.
In her new book, The Last Fire Season (out on January 16 next year), Martin writes about the fires that swept through California in 2020, weaving her personal story with that of fire in California writ large. It’s a beautiful book, and I called her up to talk about her relationship with fire and how we can learn to live with the changing world. Our conversation has been edited for length and clarity.
The book opens in 2020, which was a year of multiple fire complexes. Was that the first time fire made itself known in the immediate vicinity of your home?
No, it wasn’t. But it was the first time that I realized that it wasn’t an anomaly.
We had horrible fires near my area in 2017. In 2018, the Camp Fire happened in Northern California, which was like a four-hour drive away, but the smoke from that fire lingered in the Bay Area for weeks. And then in 2019, the Kincade fire was a huge fire up here in Sonoma, and the entire west of the county was evacuated in basically the course of a night, including ourselves.
Then in 2020, the Lightning Complex fires happened in late August, which is what the book starts with. And that was the moment where I personally was like, “oh, this is going to keep happening.”
Before that a natural disaster to me felt like a thing that happened once and then that’s it, right? It wasn’t connected to larger things for me. But the fact is that the new wildfires that we’re having are bigger and hotter and far more destructive than the previous wildfires we’ve had, and 2020, which is probably far too late, was the year that I personally put that all together under the name of climate change. It wasn’t the first year I knew about fire, but it was the moment I realized that I was going to be living with fire for the rest of my life.
I was struck by your description of the 2020 fires and the ways that COVID complicated your experience of them. It reminded me of the concept of cascading events; it was striking to read about how your go bag was filled with these N95 masks that were there for the sake of the fires, but also, of course, turned out to have utility for this other thing that you’re dealing with at the same time.
That was one of the reasons why I chose to center the book around 2020. I think that was a moment where it became clear for a lot of people that disasters don’t take their turn. When it was happening, I felt it was a historic moment.
You named your book The Last Fire Season. But, of course, it wasn’t the last.
Unfortunately not. The book began as an essay, and since I was writing it in 2021 I thought I was writing about the last fire season I had experienced. But then I realized that it was actually a really great title for a book. It’s pretty commonly acknowledged now that in the North American West, fire season isn’t really a thing anymore. Now fire authorities talk about having a fire year.
That is directly linked to the changing of the weather and the climate. But for me, the deeper meaning of it is this idea that fire being seasonal also sort of implies that it’s temporary, and that it’s going to go away. But really it’s not seasonal, it’s part of this land. And we’re going to be living with it forever.
There’s a point in your book where you write that the California ecosystem was fire-adapted, but also that fire is changing. What do you mean by that?
Since time immemorial, California’s ecosystems — from oak woodlands to redwood forests to grasslands and chaparral — evolved with fire as part of their natural cycle. Fire is actually something that helps the cycle of the landscape reset and continue.
And this was something that Indigenous people knew and really sort of harnessed and used in the way that they tended the lands. But the genocide of Indigenous people in California really sort of stopped that cycle, as is the case with colonialism in most places.
Right, you have a chapter about the Indigenous history of fire in California and the suppression of fire both through violence against Indigenous communities and also a long history of policies against fire.
Yeah, the colonial policies of managing the land in California had been what they call ”total fire exclusion,” which is basically the idea that all fire is bad and we need to extinguish fires right away. There was a policy in place called the 10 AM policy that actually said every new forest fire needs to be extinguished by 10 AM the next morning. And, you know, there are a lot of reasons why that happened, including profits and fear and prioritizing human habitat and recreation over the landscape. But the result is that the landscapes here are actually neglected at this point, 150 years after colonization.
You wrote at one point about going to prescribed burns and there was a section that really stood out to me:
Fire is exuberant. It’s joyous. It dances. I can see why people joke that all firefighters are secret pyros. It’s so much fun.
I fully relate to this feeling. Has going to prescribed burns changed your own relationship with fire?
Good fire and cultural fire, which is generally the term we use when we’re talking about Indigenous use of fire, have radically changed my feelings about fire. Humans have evolved with fire, and the more I engage with fire, the more I learn about it, the more I understand its role in both the land and the history of this place, the less afraid I feel.
You write about your own experience with getting a hysterectomy and how that affected your life afterwards, and I thought that was an interesting choice. You could have written a book that was just about fire, and we could have never learned about your hysterectomy. But you chose to include it. Can you tell me a little bit about how that came to happen?
I could have written a straight journalistic look at wildfire right now or at the 2020 fire season specifically. And that was something I toyed with. But I ultimately realized, in thinking about this idea of cascading disasters, that they’re all happening while people are living their lives. Climate change, wars, economic ruin are all happening on top of whatever else is going on in your life. So I thought this part of my life was worth including.
The hysterectomy, and many associated health crises, led me to having chronic pain. And one of the only things that helped me with that was gardening. For me, the physical act of literally touching the land, being in this dialogue with the environment and the ecosystem around me, was the thing that helped me recover from this health crisis. I wasn’t quite well. And more importantly, nature wasn’t quite well. And gardening in this environment is what really made it click for me that this environment is going through a crisis as well.
That garden was partly how you knew about the oncoming fires in 2020, right?
Yeah, when the Lightning Complex fires started, I was out in my garden watering the roses. I saw this little black object on the ground, and when I leaned down and picked it up I saw it was a leaf of a California bay laurel tree. And it was burned black, but it was still whole. It had been blown on the wind and landed in my garden. It was sort of like a messenger, telling me that a few miles away these trees were burning.
Bay trees are a natural part of the forest understory here, but they are highly flammable. They’re basically made of oil, and they serve as what’s called a ladder fuel; if fire gets in that tree, it will shoot up it and then can get into the crowns of taller trees like redwoods or oaks that would normally be more fire resistant. It’s literally a fire spreader. Anyone who lives in the area will tell you that when there’s a fire nearby it rains burnt leaves.
Parts of the book are unexpectedly written in the past tense. You write, for example, that “Northern California was a very large place,” but the depictions of events in the past or future are written in the present tense. Was that intentional? Did you mean to contract the idea of Northern California?
I absolutely did. The convention in nonfiction is to write events in the past tense, but to phrase facts, or things that are still true, in the present tense. I felt like it was important to acknowledge that the things we take as granted, these truths about the way the environment works, might not always remain that way. It was also partly a pragmatic decision, because I didn’t know what would happen before the book came out. What if my house burned down before that, or if I have to move? Things are just so chaotic right now.
The other time I break with convention is when I write about Indigenous nations and Indigenous management practices. I intentionally used the present tense there as a way to push back against the trope of a lot of non-Indigenous writers portraying Indigenous people and worldviews as extinct when in fact they’re very, very alive.
Throughout the book you’re constantly talking to your partner about whether to stay in your home or move away to a “safer” area. I think it can be really hard for people who don’t live in areas under threat to grasp just how hard the concept of migrating really is.
Right, that’s such a common binary: to stay or go. And the reality is actually a lot messier. I’m fortunate to even have the choice of whether to stay or go; I am a person who has a lot of different privileges. I have resources, I have friends, I’m educated, I’m white.
Most people don’t willingly leave their homes unless things are really bad. But it’s never really all bad: Sometimes there’s extreme weather and disasters, and then there isn’t. It’s up and down. There’s a lot of talk around what the perfect solution is, where the safe places are. And the truth is that nowhere is safe because of climate change.
For me, the point of living at this moment on this planet is that it’s messy. It’s full of grief, it’s full of joy and beauty, and it’s also dangerous. There may be a time when I leave this place, for a variety of reasons. But I think the idea that you can run away from climate change is false.
Something I’ve learned a lot from talking with people who are deeply connected to the land here and who work with fire is that you have a responsibility to the place where you live. If I love this place so much, what do I owe it? The idea of tending a place for its overall health, not just for my personal survival, is very powerful.
Right, at one point you write about you and your partner thinking about doing prescribed burns in the woods near you to help reduce the risk of more fires.
We have thought a lot about the idea of reintroducing good fire where we live. Our neighborhood has been getting together and doing work days where we clear fuels from the forest floor together. And it’s really proof of how much work is needed, because you can clear brush and cut dead limbs off trees for a day with a group of 15 people, and then you look at this tiny quarter acre that you’ve worked on, and it still needs so much more work.
Stewardship is a constant act.
Absolutely. And it might not be perfect, and honestly it might not make a difference. These woods might still burn. But if and when they do burn, they are going to be healthier afterwards because the fire is going to be healthier.

On Massachusetts’ offshore headwinds, Biden’s gas rules, and Australia’s free power
Current conditions: The Pacific Northwest is getting blasted with winds of up to 70 miles per hour • Heavy snow is coming this week for the higher elevations in New England and upstate New York • San Cristóbal de La Laguna in the Canary Islands saw temperatures surge to 95 degrees Fahrenheit.

Democratic candidates swept to victory in key races with implications for climate change on Tuesday night. In Virginia, Democrat Abigail Spanberger — who vowed to push forward with offshore wind, new nuclear reactors, and fusion energy — seized the governor’s mansion in the first major race to be called after polls closed. In New Jersey, Democrat Mikie Sherrill, who campaigned on building new nuclear plants and pressing the state’s grid operator, PJM Interconnection, to cut electricity prices, trounced her Republican opponent. In New York City, Democrat Zohran Mamdani, who said little about energy during his campaign but came out in the last debate in favor of nuclear power, easily beat back his two rivals for Gracie Mansion. Yet the Georgia Public Service Commission's incumbent Republican Tim Echols lost his race against Democrat Alicia Johnson, a defeat for a conservative who championed construction of the only two nuclear reactors built from scratch in modern U.S. history. In what one expert called a sign of a “seismic shift” on the commission, Peter Hubbard, another Democrat running to flip a seat on the commission, also won.
At a moment when the Trump administration is “disassembling climate policy across the federal government,” Heatmap’s Emily Pontecorvo wrote, “state elections are arguably more important to climate action than ever.”
A federal judge in Washington ruled Tuesday that the Trump administration can reconsider the Biden-era approval of SouthCoast Wind off the coast of Nantucket, Massachusetts. The decision, reported in The New York Times, is a setback for the joint venture between EDP Renewables and Engie, and handed the White House a victory in what we’ve called here the administration’s “total war on wind.” Judge Tanya S. Chutkan of the U.S. District Court for the District of Columbia ruled that the project developers would not “suffer immediate and significant hardship” if the Department of the Interior’s Bureau of Ocean Energy Management were allowed to reevaluate the project’s construction and operation permits.

Meanwhile, the U.S. Court of Appeals for the D.C. Circuit upheld Biden-era Department of Energy efficiency rules for gas-fired residential furnaces and commercial water heaters in a ruling that rejected the gas industry’s challenge on Tuesday. “Overall, we find that DOE’s economic justification analysis and conclusions were robust,” the panel ruled, according to Bloomberg Law. The decision will maintain the status quo of how the agency enforces energy efficiency rules for the appliances. Under standards updated in 2021 and 2023, the Biden-era bureaucrats proposed raising efficiency levels to 95% for furnaces and using condensing model designs to heat water.
White House budget officials pressed the Environmental Protection Agency to expand its rollback of tailpipe regulations this summer as the agency sought to repeal the foundational policy that undergirds federal climate rules, E&E News reported. Documents the green newswire service obtained showed the White House Office of Management and Budget pushed the environmental regulator to weaken limits on vehicular pollution, including soot and smog-forming compounds in addition to planet-heating carbon. The EPA initially pushed back, but the documents revealed the staffers at OMB demanded the agency pursue a more aggressive rollback.
Australia launched a new plan to force energy companies to offer free electricity to households during the day to use excess solar power and push the grid away from coal and gas. The policy, called the “Solar Sharer” plan, aims to take advantage of the country’s vast rooftop solar panels. More than 4 million of Australia’s 10.9 million households have panels, and the capacity has overtaken the nation’s remaining coal-fired power stations. The proposal, the Financial Times reported, would also extend the benefits of distributed solar resources to the country’s renters and apartment dwellers.
For years, nuclear scientists have dreamed of harnessing atomic energy from thorium, potentially shrinking radioactive waste and reducing the risk of weapons proliferation compared to uranium. In the West, that has remained largely a dream. In China, however, researchers are vaulting ahead. This week, Chinese scientists announced a major breakthrough in converting thorium to uranium in a reactor. “This marks the first time international experimental data has been obtained after thorium was introduced into a molten salt reactor, making it the only operational molten salt reactor in the world to have successfully incorporated thorium fuel,” Shanghai Institute of Applied Physics of the Chinese Academy of Sciences said in a statement.
Rob and Jesse touch base with WeaveGrid CEO Apoorv Bhargava.
Data centers aren’t the only driver of rising power use. The inexorable shift to electric vehicles — which has been slowed, but not stopped, by Donald Trump’s policies — is also pushing up electricity use across the country. That puts a strain on the grid — but EVs could also be a strength.
On this week’s episode of Shift Key, Rob and Jesse talk to Apoorv Bhargava, the CEO and cofounder of WeaveGrid, a startup that helps people charge their vehicles in a way that’s better and cleaner for the grid. They chat about why EV charging remains way too complicated, why it should be more like paying a cellphone bill than filling up at a gas station, and how the AI boom has already changed the utility sector.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:
Robinson Meyer: In your experience, are consumers willing to make this deal, where they get some money off on their power bill in order to change how their car works? Because it does seem to include a mindset change for people, where they’re going from thinking of their car as a machine — I mean, this is part of the broader transition to EVs. But there’s an even further mindset shift that seems to me like it would be required here, where you go from thinking about your car as a machine that you wholly own — that enables your freedom, that is ready to drive a certain amount of miles at any time — to a machine that enables you to have transportation services but also is one instantiation of the great big cloud of services and digital technologies and commodity energy products that surround us at any time.
Apoorv Bhargava: Yeah, I mean, look, I think we have seen faster adoption rates than any other consumer-side resource participating in energy has. So I feel very good about that. But ultimately, I think of this as a transition to the normal experience for folks who are going through what is a new experience altogether.
Again, similar to my cell phone plan, if this was just offered to me as a standard offering — you buy an EV, your utility offers you a plan, it’s called the EV plan — in the same way that we have EV time-of-use rates, quote-unquote. If you’re just offered an EV plan where it’s exactly the same thing — I’m going to make sure you’re fully charged every night in the way you want it to be charged, with the cleanest, cheapest, most reliable charging possible, and it’s just being taken care of.
I think what’s so hard for most folks to grok, is that the way this experience works is it’s supposed to be completely frictionless, right? You’re really supposed to not think about it. It’s actually only in the few moments where you need to change your 99% behavior to the 1% behavior — where you’re like, Oh, I need to go to the airport, or, Oh, I need to go on a road trip. That’s where you need to think about it. It’s flipped from thermostat management programs where you actually need to think about it actively in the moments where the grid is really strained.
Where we’ve overinvested, in my view —and this is a controversial view — we’ve overinvested in trying to make EVs be like gas stations or like the gas station model. We keep talking about it all the time. We’ve over-talked about range anxiety. The fact of the matter is 80% of charging still happens at home. Even in the long run, 30% of charging will happen in the workplace. 50- plus-percent will happen at home. It’s very little charging that’s gonna happen on fast charging. But we’ve talked so much, ad nauseam, about fast charging that we’ve actually forgotten that underpinning the iceberg of the electrification cost is the grid itself. And never before has the grid been so strained.

The self-described “ecosocialist” ran an ultra-disciplined campaign for New York City mayor. Once he’s in office, the climate issue could become unavoidable.
Zohran Mamdani, the New York state assemblyman, democratic socialist, and Democratic nominee, was elected mayor of New York City on Tuesday night.
Many factors fueled his longshot rise to Gracie Mansion — a congested primary field, a gleam-in-his-eyes approach to new media, and an optimistic left-wing worldview rendered newly credible by global tumult — but perhaps above all was a nonstop, months-long performance of bravura message discipline. Since the Democratic primary began in earnest earlier this year, Mamdani has harped in virtually every public appearance on what he has described as New York’s “affordability crisis,” promising to lower the city’s cost of living for working-class residents.
He hammered that message even as the election required him to play a shifting set of roles. During the primary, he set himself apart from a field overflowing with progressives by showcasing his differences with the Democratic Party. During the general election, he became the consummate Democrat, earning the votes of the party’s most loyal voters even as the former governor and one-time old-guard Democrat Andrew Cuomo ran an independent bid. Fittingly, Mamdani’s victory speech Tuesday night alluded to and remixed lines from socialists and liberal Democrats alike — including Cuomo’s father, New York’s former governor Mario Cuomo.
“A great New Yorker once said that while you campaign in poetry, you govern in prose,” Mamdani said, paraphrasing the elder Cuomo. “If that must be true, let the prose we write still rhyme, and let us build a shining city for all.”
So given all the notes he struck during the campaign, it is revealing to consider those Mamdani left unplayed. One in particular stands out: Throughout the long mayoral campaign, Mamdani rarely spoke about climate change — often doing so only when directly asked.
This might not seem meaningful on its face. Mamdani had a lot of issues he could focus on, after all. (He also spoke intermittently about, say, K-12 education, even though as mayor he will oversee the nation’s largest school district.)
But in light of his biography, Mamdani’s relative reticence on climate change stands out. During his early career in the state legislature, Mamdani defined himself in part through his climate activism, and by his view that New York should be “leading the country in our fight against the climate crisis,” as he said in a 2022 press release. He helmed some of the most aggressive recent activist efforts to shut down, block, and replace fossil fuel infrastructure in Gotham. They provide a window into where his mayoralty could go — and also illustrate the fraught politics of climate change in Year 1 of Trump 2.0.
From his first days in the New York State Assembly in 2021, Mamdani placed himself at the forefront of the debate over the future of fossil fuels in New York’s energy system. “When I ran for this office, it was on a platform of housing, justice, and energy for all,” he said in a statement soon after his election.
Many of his biggest policy proposals as a legislator focused on climate change. He backed the Build Public Renewables Act, a bill that empowers New York’s state power agency to develop wind and solar projects in order to meet the state’s climate goals. He resisted NRG Energy’s push to replace an aging natural gas peaker plant in Astoria, Queens, with a newer power plant that would still burn gas. And he opposed the expansion of natural gas pipelines into the state while cosponsoring the Clean Futures Act, which would, he said, ban all new natural gas power plants across New York.
Climate change was the issue, he said, at the very heart of his political identity. In July 2022, after the state assembly expired without a vote on the Build Public Renewables Act and amid a heat wave in New York, he called for a special session to pass the bill, deeming climate change a “human catastrophe.”
“There are a number of bills that I would love to pass tomorrow. I’m not calling for a special session for all of them,” he told Spectrum News. “The reason we have to call for this one is because climate change is not waiting.”
In its fight against the Queens power plant, his legislative office — working alongside the Stop NRG Coalition, an alliance of local residents, the Democratic Socialists of America, and traditional environmentalists such as Earthjustice and the Sierra Club — called 36,000 households and sent more than 7,800 postcards asking residents to reject the plant, Mamdani later said. Ultimately, locals filed more than 6,000 comments to oppose the proposed plant; when the New York Department of Environmental Conservation ultimately denied a key permit in October 2022, Mamdani claimed victory.
He was also clear about who had lost that fight: big corporations and fossil fuel-aligned capitalism. “This shows when we organize against corporations that put capital over the collective, we can win a world where we all live with dignity,” he said. “Stopping the Astoria power plant is an amazing victory towards a habitable planet and the clean future we all deserve.”
Many of Mamdani’s other climate efforts were ultimately successful. The Build Public Renewables Act passed in April 2023 as part of the state budget and was signed into law by Governor Kathy Hochul. The state has not passed the Clean Futures Act, although regulators have rejected other proposed fossil-fuel power plants across the state, citing its 2019 climate leadership law.
In a little-watched May 2021 video that gives a concentrated dose of Mamdani’s political vision at the time, he described himself not as a socialist, but as a “proud ecosocialist” who believed that electricity should be treated as a “public good.”
“Did you ever wonder why New York state only gets 5% of its energy from wind and solar?” he asked in the video. “It’s because of one word: capitalism.” The way to fight that capitalistic hold on energy production, he said, was with public power — government ownership and development of zero-carbon generation.
Even after those victories, Mamdani remained a proud champion of climate issues. As recently as a year ago, he suggested that activism and agitation around climate change was a key way that progressives could differentiate themselves from Trump in the eyes of the working class. At a rally in late November last year, shortly after a drought resulted in a rare brush fire that consumed 2 acres of the city’s beloved Prospect Park, he exhorted the New York Power Authority, or NYPA, to move faster to develop its pipeline of renewables projects — and framed credible climate action as essential to countering Trump’s rise.
“The climate crisis does not care about any of the reasons that are usually given so much weight in Albany. It doesn’t care if you want to blame the supply chain. It doesn’t care if a private company says it has reduced profitability. It cares only if you build out renewable infrastructure,” he said.
“If you want to know how to defeat the Donald Trump far-right movement, it’s by showing we actually have a workable alternative,” he continued. “Because if working class people can’t breathe the air, if they can’t afford to live in the city they call home because they can’t find a union job, and if they look around at their favorite parks being on fire, why would they trust us?”
“It is time to show them why,” he concluded. “It’s time for the Build Public Renewables Act.”
Mamdani has continued to push for NYPA to accelerate its renewables construction — he posted a video of the same rally to his Instagram feed in September, encouraging his followers to file public comments with New York state.
As recently as February 2025, he described New York City as facing an “existential moment of our climate crisis” at a candidate forum, and said that enforcing the city’s climate laws would require “taking on the real-estate industry.”
But in the months since, his earlier bold rhetoric — casting practical concerns as no object when it comes to climate action — has faded, and he has evinced more sympathy for landlords and homeowners who may bear decarbonization’s costs. He still describes climate change in existential terms, but has become far less likely to bring it up unbidden in his own speeches and media appearances.
As a major party mayoral candidate, too, Mamdani largely avoided framing climate action as a necessary antidote to Trumpism. When seeking to contrast himself with the president, he focused almost entirely on cost of living issues. In a Fox News appearance in October, Mamdani addressed Trump directly and said that he would work with him to address New Yorkers’ cost of living.
His campaign website’s only stated climate proposal is a “Green Schools” plan to renovate 500 public schools, turn 500 asphalt schoolyards into green spaces, and construct “resilience hubs” at 50 schools. Speaking with The Nation in April — in one of his few recent long-form interviews on climate policy — Mamdani set that plan within his broader campaign, saying “climate and quality of life are not two separate concerns. They are, in fact, one and the same.” Schools, he said, offer “an opportunity for comprehensive climate action.”
But his website has few other details about what climate actions he might like to pursue once he takes office as mayor. Indeed, the candidate who once blamed capitalism for New York’s failure to build renewables is now promising to establish a “Mom-and-Pop Czar” to cut fines on small businesses and speed up permitting. It also gives few clues about how Mamdani would handle decarbonization’s inevitable trade-offs. If achieving a faster renewables buildout led to higher energy prices for consumers and small businesses, what would he do?
Even in situations where his slogans could reasonably connect to some climate benefit, Mamdani did not complete the handshake. His website does not mention the pollution benefits of fast and free bus service, for instance, even though free transit in other campaigns has been described as a climate policy. His 25-minute victory speech, delivered to a jubilant crowd on Tuesday night, did not mention climate change at all.
Regardless of what he’s said, Mamdani will be required to take big actions on climate policy as mayor. The most significant will likely arise from an ordinance called Local Law 97, which requires New York City’s large buildings to reduce their greenhouse gas emissions by 2050. That law’s strict new set of pollution caps and penalties will start in 2029, and many landlords are set to pay big fines. During the second mayoral debate, Mamdani repeated that the “climate crisis is one of the most pressing issues facing this city,” and said he wants the law’s fines to be enforced. But he also added that “the city should make it easier for buildings to comply.”
Mamdani has also argued that the city and state should renew a set of tax breaks to make it cheaper for large residential buildings, like condos and co-ops, to meet the law’s targets, and has proposed creating a “one-stop shop” for Local Law 97 compliance in the city governance, according to his debate remarks and a memo about homeowner policy released by his campaign.
In replacing climate change with cost of living, Mamdani has moved closer to what appears to be an emerging consensus among his party. Recent autopsies of the 2024 election have argued that voters believed Democrats were too focused on issues like climate change and not enough on affordability or inflation. Mamdani’s relentless focus on near-term costs — and his embrace of clear, actionable, and frankly non-climate-related slogans — suggests that one young ecosocialist might now agree with them. His ultimate victory suggests that it wasn’t a bad gamble.
