The president isn’t trying to cut emissions as fast possible. He’s doing something else.

Here’s the problem with President Joe Biden’s climate policy: From a certain point of view, it makes no sense.
Take his electricity policy. At the top level, Biden has committed to eliminating greenhouse-gas pollution from the power sector by 2035. He wants to accomplish this largely by making clean energy cheaper — that’s the goal of the Inflation Reduction Act, of course — and he has also changed federal rules so it’s slightly easier to build power lines and large-scale renewable projects. He has also added teeth to that goal in the form of new Environmental Protection Agency rules cracking down on coal and natural gas.
Yet at the same time, Biden has seemingly also made it more difficult to decarbonize. Last week, he raised tariffs on cheap solar panels and grid-scale batteries made in China. And he ended the two-year “solar bridge,” a tariff exemption for some Chinese-based solar manufacturers that operated in other countries. That means that as soon as next month, some eye-watering tariffs — possibly as high as 254% — could apply to many U.S. solar imports.
Then there’s Biden’s policy on electric cars. The president wants 50% of all new vehicles sold in the U.S. to be EVs or plug-in hybrids by 2030, and he has overseen billions of dollars of spending aimed at building a national charging network. His climate law discounts the price of many EVs by $7,500 and directly subsidizes virtually every battery and vehicle made in America. Yet he recently put 100% tariffs on EV imports from China, the country that makes some of the world’s cheapest and best electric cars.
This combination is, frankly, a little confusing. And it has confounded critics around the world: It can sometimes seem like the president is cutting the cost of clean energy with one hand while raising it with another. “The Biden effect will be to raise the U.S. domestic price of EVs, solar panels and other green inputs and delay America’s energy transition,” writes Edward Luce of the Financial Times. The Economist, in high dudgeon, lectured Biden for forgetting his David Ricardo.
There is certainly much to criticize about Biden’s climate policy, but reading coverage of it, I’m often struck by how little the commentator seems to understand what the policy is trying to do. There is, as Noah Smith and Matt Yglesias have written, a strong national-security component to the tariffs announced last week. But there’s more to these policies than national security alone. Although the president’s actions can sometimes seem contradictory, there is in fact a logic to what Biden is trying to do on climate change. And without defending the policy, I think it is important to describe it accurately.
Let’s back up. For the past 30 years, climate advocates tried to raise the cost of fossil fuels in America by imposing a carbon price. Taxing carbon pollution is the most elegant and economically efficient way to solve climate change, and — at least in theory — it doesn’t require the kind of fine-tuned economic tampering that the Biden administration is engaged in. Or at least that’s what the economists say — I remain skeptical that a carbon tax alone would have succeeded in decarbonizing the economy without additional policy.
And in any case, the point is moot: Climate advocates never succeeded in passing such a price. Voters were understandably resistant to raising the cost of energy, especially gasoline, and no coalition emerged to persuade politicians that the political costs of a carbon tax would be worth bearing. During many of those years, too, the American economy was so understimulated that passing a revenue-raising tax made little political sense: There was effectively no public constituency for deficit reduction.
By 2020, Democrats had largely given up on this approach. Although many still believe that a carbon tax could be an effective decarbonization tool, they instead adopted a new political economic philosophy. Simplified somewhat, it goes something like:
1. The biggest obstacle to passing American climate policy is the lack of a domestic coalition that supports the deep and continued decarbonization of the domestic economy.
2. Passing climate policy has been so hard historically because a powerful and geographically diverse set of companies, unions, state, and local officials, and political donors — largely but not entirely in the fossil fuel industry — don’t want to see the U.S. move away from oil and natural gas. They’re backed up by status-quo-favoring consumers.
3. The central aim of near-term climate policy, then, should be to create an enduring coalition to support the continued decarbonization of the U.S. economy.
This is the guiding logic of Biden’s climate policy: that American politics must have a powerful, durable, and flexible pro-decarbonization coalition if the U.S. is to succeed in reaching net zero. Achieving this coalition is the underlying aim of the IRA, the EPA rules, and — yes — the recent tariffs.
This is what I wish critics understood about the president’s climate strategy: Biden’s strategy won’t have succeeded if the U.S. makes some headway on emissions but imports all of its decarbonization tech from China. The U.S. actually has to develop its own supply chain and manufacturing base to build the kind of deep economic coalition that can sustain long-term decarbonization. This is why trade restrictions have become so central to the administration’s world view.
I should add that for all that the administration emphasizes “good-paying union jobs” in its messaging around climate policy, jobs alone aren’t necessarily the goal of this strategy. Critics of American industrial policy sometimes point out that, even in China, the labor share of manufacturing is falling; indeed, one of China’s great manufacturing advantages is the extent to which it has automated its assembly lines. But that may not necessarily matter to coalition politics: As the political scientist Nina Kelsey has shown in her research on the Montreal Protocol, companies tend to support environmental policy when doing so will help their large-scale, fixed investments — essentially, their factories — not their labor force.
There are big risks to Biden’s strategy. The next administration — which in this moment looks likely to be helmed by Donald Trump — could repeal the production and installation subsidies for renewables but leave the tariffs in place. That would devastate the finances of domestic solar manufacturers and significantly slow down the decarbonization of America’s grid, and it would mean that Americans who want to import cheap solar panels wouldn’t be able to. That would essentially freeze America’s decarbonization effort while the rest of the world races ahead.
Even if Biden wins, the kind of economic management that he’s trying to do may simply not be possible in the federal system — or, for that matter, with the existing Democratic coalition. There may be too many interest groups to placate or too many obstacles to building. California offers a warning about how well-intentioned liberal policy can prevent enough new infrastructure from getting built.
Still a third risk is that the American solar manufacturing industry meets domestic demand but doesn’t become very competitive, so it doesn’t reduce costs aggressively. A relatively small number of firms actually make solar panels in the United States, and they have to compete for engineering talent with more established industries like software. What has brought down the cost of solar in China isn’t subsidies per se, but an intensely competitive and very large domestic market. It isn’t clear that the American market for solar power will attain such scale or efficiency.
These would, obviously, be lasting setbacks for American decarbonization. But even in critiquing this set of policies, I hope the world notes what a different problem America faces when taking on climate change as compared to the rest of the world. Most countries import more oil than they produce, meaning their fossil-fuel addiction shackles their currencies and economies to a volatile global commodity. They are only too happy to move away from fossil fuels, and especially oil, provided that a cheap and acceptable alternative is available. In the United Kingdom, for instance, cross-partisan support for decarbonization policy has existed since the era of Margaret Thatcher.
In the United States, with our oil-drenched politics, the task is different. Only a sufficiently powerful pro-climate coalition will be able to unseat the fossil fuels enthroned atop our economy. Forging this coalition — even if it slows down decarbonization for a few years — is Biden’s true goal. Whether that’s worth it is another story.

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.”
