At a New York Mets game this weekend, I saw something I’m not used to seeing until late summer. No, not the inexplicable late-season implosion of a beloved local franchise — a neon-red setting sun.
West Coasters know this sun well. I call it the “Eye of Sauron” sun; others say it’s “blood-red.” In reality, the color is harder to describe, more like the red-orange-pink insides of a halved grapefruit. It feels unnatural and eerie, and is the effect of shorter wavelengths of light being filtered out of a sunrise or sunset by particles in the air caused by pollution, including wildfire smoke.
I immediately grabbed my phone to find the source of the haze, but a quick Google search of “Where is this smoke coming from?” didn’t turn up any immediate results. In fact, it can be frustratingly difficult to figure out the origin of wildfire smoke when you see or smell it. This only gets more difficult as fire season wears on; is the smoke you’re inhaling from a small nearby fire, or part of a bigger burn blowing in from somewhere else?
Unfortunately, there isn’t a handy app yet that will simply tell you “the smoke overhead is from the Canadian fires” — which, in the case of the pollution I was experiencing in Flushing Meadows, it actually was. But you can cobble together an answer about where smoke is coming from by using a few different methods.
When you climb a mountain, an inaccurate forecast can be the difference between life and death. I learned about the MyRadar app from an experienced mountaineering guide who swears it is the most accurate weather app on the market. It’s also become my go-to app for figuring out where the wildfire smoke I’m inhaling is coming from.
The app pulls data from the United States Geological Survey, InciWeb, and the United States Forest Service’s Risk Incident Information Management System to build its smoke and fire maps (it also received a wildfire detection grant from the National Oceanic and Atmospheric Administration last year). Hovering over my house at around 2 p.m. on Monday, the app clearly told me I was experiencing “moderate air quality” and “heavy smoke hazard.” Zooming out, it’s easy to guess based on the shape of the “heavy smoke hazard” cloud that the pollution is wrapping down from the massive fires burning in Alberta, Saskatchewan, and British Columbia. You can also overlay wind patterns on the app for further confirmation.

MyRadar’s visuals can get a little cluttered, though, and parsing this information still leaves you with an informed guess. But it’s one that can be easily cross-checked against the EPA’s AirNow app.
The EPA app is a little more straightforward: It gives users an upfront measurement of their air quality index, or AQI, which, with a click, can be broken down into “primary pollutants.” In the case of New York City on Monday, it was PM2.5, the expected particle from wildfire smoke (and also “the bad one” when it comes to your health). The app also shows a “forecast” of how the AQI is expected to develop over the coming hours; in New York’s case, it was going to get worse before it got better.
The AirNow app additionally has a “smoke” tab that shows a similar smoke plume overlay as MyRadar’s. By clicking on the globe in the upper left-hand corner, you can view additional fire information, including how far away the nearest burn is, and confirm if you’re under a smoke plume. Using these two pieces of information together, you can further deduce if the smoke you’re experiencing is blowing in from somewhere far away or nearby (some of New York’s smoke may be from the Cannon Ball 2 Fire to our northwest, in Passaic County, New Jersey, but the app shows me that fire is fairly small — 107 total acres — and so in this case, it is not the main culprit).

The BlueSky Canada Smoke Forecasting System (FireSmoke Canada) is run by the University of British Columbia, and while it has an emphasis on Canadian air quality, it is run in partnership with the United States Forest Service and includes U.S. data too. The FireSmoke Canada website specifically tracks PM2.5 smoke particles at ground level from wildfires across North America (“ground level” is an important distinction because sometimes smoke plumes will be too high in the atmosphere to actually affect your health). The FireSmoke Canada map throws in a time-lapse animation and for my purposes, it clearly showed that the smoke in New York was coming down from the Canadian fires.
The FireSmoke Canada map is also a great way to figure out the origin of local fire smoke too since it often shows plumes from even small blazes (though it has technical limitations too, which it details in its FAQ). Unfortunately, the service doesn’t allow users to click on a fire to learn more information about it, which means toggling back and forth between the AirNow or MyRadar app, or the FIRMS U.S./Canada website, to get a fuller picture of what is going on.

Other discrepancies between the apps can be frustrating; AirNow, for example, still shows the Great Lakes Wildfire as burning in North Carolina, though it’s not appearing on FireSmoke Canada’s tracker; MyRadar provides the most context, showing the containment at 90% and labeling its status as “minimal.” On the other hand, MyRadar and AirNow don’t show a fire near Hanford, Washington, while MySmoke Canada does.
Short of doing your own detective work with various wildfire tracking services, local media otherwise remain the best option for figuring out where smoke is coming from. The Hanford blaze that eluded MyRadar and AirNow, for example, is easily confirmed by the regional press; started by lightning, the fire reportedly burned around 1,000 acres and is now 100% contained.
Turns out, Googling “Why is it smoky outside” — while it might feel archaic — still might be one of the best options.

Current conditions: Temperatures as low as 30 degrees Fahrenheit below average are expected to persist for at least another week throughout the Northeast, including in New York City • Midsummer heat is driving temperatures up near 100 degrees in Paraguay • Antarctica is facing intense katabatic winds that pull cold air from high altitudes to lower ones.

The United States has, once again, exited the Paris Agreement, the first global carbon-cutting pact to include the world’s two top emitters. President Donald Trump initiated the withdrawal on his first day back in office last year — unlike the last time Trump quit the Paris accords, after a prolonged will-he-won’t-he game in 2017. That process took three years to complete, allowing newly installed President Joe Biden to rejoin in 2021 after just a brief lapse. This time, the process took only a year to wrap up, meaning the U.S. will remain outside the pact for years at least. “Trump is making unilateral decisions to remove the United States from any meaningful global climate action,” Katie Harris, the vice president of federal affairs at the union-affiliated BlueGreen Alliance, said in a statement. “His personal vendetta against clean energy and climate action will hurt workers and our environment.” Now, as Heatmap’s Katie Brigham wrote last year, at “all Paris-related meetings (which comprise much of the conference), the U.S. would have to attend as an ‘observer’ with no decision-making power, the same category as lobbyists.”
America has not yet completed its withdrawal from the United Nations Framework Convention on Climate Change, the overarching group through which the Paris Agreement was negotiated, which Trump initiated this month. That won’t be final until next year. That Trump is even planning to quit the body shows how much more aggressive the administration’s approach to climate policy is this time around. Trump remained within the UNFCCC during his first term, preferring to stay engaged in negotiations even after quitting the Paris Agreement.
Just weeks after a federal judge struck down the Trump administration’s stop work order on the Revolution Wind project off Rhode Island’s shores, another federal judge has overturned the order halting construction on the Vineyard Wind project off Massachusetts. That, as Heatmap’s Emily Pontecorvo wrote last night, “makes four offshore wind farms that have now won preliminary injunctions against Trump’s freeze on the industry.” Besides Revolution Wind, Dominion Energy’s Coastal Virginia offshore wind project and Equinor’s Empire Wind plant off Long Island have each prevailed in their challenges to the administration’s blanket order to abandon construction on dubious national security grounds.
Meanwhile, the White House is potentially starving another major infrastructure project of funding. The Gateway rail project to build a new tunnel under the Hudson River between New Jersey and New York City could run out of money and halt construction by the end of next week, the project manager warned Tuesday. Washington had promised billions to get the project done, but the money stopped flowing in October during the government shutdown. Officials at the Department of Transportation said the funding would remain suspended until, as The New York Times reported, the project’s contracts could be reviewed for compliance with new rules about businesses owned by women and minorities.

A new transmission line connecting New England’s power-starved and gas-addicted grid to Quebec’s carbon-free hydroelectric system just came online this month. But electricity abruptly stopped flowing onto the New England Clean Energy Connect as the Canadian province’s state-owned utility, Hydro-Quebec, withheld power to meet skyrocketing demand at home amid the Arctic chill. Power plant owners in New England and New York, where Hydro-Quebec is building another line down the Hudson River to connect to New York City, complained that deals with the utility focused on maintaining supplies during the summer, when air conditioning traditionally surges power to peak demand. Hydro-Quebec restored power to the line on Monday.
The storm represented a force majeure event. If it hadn’t, the utility would have needed to pay penalties. But the incident is sure to fuel more criticism from power plant owners, most of which are fossil fueled, who oppose increased competition from the Quebecois. “I hate to say it, but a lot of the issues and concerns that we have been talking about for years have played out this weekend,” Dan Dolan — who leads the New England Power Generators Association, a trade group representing power plant owners — told E&E News. “This is a very expensive contract for a product that predominantly comes in non-stressed periods in the winter,” he said.
Europe has signed what the European Commission president Urusula von der Leyen called “the mother of all deals” with India, “a free trade zone of 2 billion people.” As part of the deal, the world’s second-largest market and the most populous nation plan to ramp up exports of steel, plastics, chemicals, and pharmaceuticals. But don’t expect Brussels to give New Delhi a break on its growing share of the global emissions. The EU’s carbon border adjustment mechanism — the first major tariff in the world based on the carbon intensity of imports — just took effect this month, and will remain intact for Indian goods, Reuters reported.
The Department of the Interior has ordered staff at the National Park Service to remove or edit signs and other informational materials in at least 17 parks out West to scrub mentions of climate change or hardship inflicted by settlers on Native Americans. The effort comes as part of what The Washington Post called a renewed push to implement Trump’s executive order on “restoring truth and sanity to American history.” Park staff have interpreted those orders, the newspaper reported, to mean eliminating any reference to historic racism, sexism, LGBTQ rights, and climate change. Just last week, officials removed an exhibit at Independence National Historical Park on George Washington’s ownership of slaves.
Tesla is going trucking. The electric automaker inked a deal Tuesday with Pilot Travel Centers, the nation’s largest operator of highway pit stops, to install Tesla’s Semi Chargers for heavy-duty electric vehicle charging. The stations are set to be built at select Pilot locations along Interstate 5, Interstate 10, and several other major corridors where heavy-duty charging is highest. The first sites are scheduled to open this summer.
Rob talks with McMaster University engineering professor Greig Mordue, then checks in with Heatmap contributor Andrew Moseman on the EVs to watch out for.
It’s been a huge few weeks for the electric vehicle industry — at least in North America.
After a major trade deal, Canada is set to import tens of thousands of new electric vehicles from China every year, and it could soon invite a Chinese automaker to build a domestic factory. General Motors has also already killed the Chevrolet Bolt, one of the most anticipated EV releases of 2026.
How big a deal is the China-Canada EV trade deal, really? Will we see BYD and Xiaomi cars in Toronto and Vancouver (and Detroit and Seattle) any time soon — or is the trade deal better for Western brands like Volkswagen or Tesla which have Chinese factories but a Canadian presence? On this week’s Shift Key, Rob talks to Greig Mordue, a former Toyota executive who is now an engineering professor at McMaster University in Hamilton, Ontario, about how the deal could shake out. Then he chats with Heatmap contributor Andrew Moseman about why the Bolt died — and the most exciting EVs we could see in 2026 anyway.
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. Jesse is off this week.

Here is an excerpt from our conversation:
Robinson Meyer: Over the weekend there was a new tariff threat from President Trump — he seems to like to do this on Saturday when there are no futures markets open — a new tariff threat on Canada. It is kind of interesting because he initially said that he thought if Canada could make a deal with China, they should, and he thought that was good. Then over the weekend, he said that it was actually bad that Canada had made some free trade, quote-unquote, deal with China.
Do you think that these tariff threats will affect any Carney actions going forward? Is this already priced in, slash is this exactly why Carney has reached out to China in the first place?
Greig Mordue: I think it all comes under the headline of “deep sigh,” and we’ll see where this goes. But for the first 12 months of the U.S. administration, and the threat of tariffs, and the pullback, and the new threat, and this going forward, the public policy or industrial policy response from the government of Canada and the province of Ontario, where automobiles are built in this country, was to tread lightly. And tread lightly, generally means do nothing, and by doing nothing stop the challenges.
And so doing nothing led to Stellantis shutting down an assembly plant in Brampton, Ontario; General Motors shutting an assembly plant in Ingersoll, Ontario; General Motors reducing a three-shift operation in Oshawa, Ontario to two shifts; and Ford ragging the puck — Canadian term — on the launch of a new product in their Oakville, Ontario plant. So doing nothing didn’t really help Canada from a public policy perspective.
So they’re moving forward on two fronts: One is the resetting of relationships with China and the hope of some production from Chinese manufacturers. And two, the promise of automotive industrial policy in February, or at some point this spring. So we’ll see where that goes — and that may cause some more restless nights from the U.S. administration. We’ll see.

A federal judge in Massachusetts ruled that construction on Vineyard Wind could proceed.
The Vineyard Wind offshore wind project can continue construction while the company’s lawsuit challenging the Trump administration’s stop work order proceeds, judge Brian E. Murphy for the District of Massachusetts ruled on Tuesday.
That makes four offshore wind farms that have now won preliminary injunctions against Trump’s freeze on the industry. Dominion Energy’s Coastal Virginia offshore wind project, Orsted’s Revolution Wind off the coast of New England, and Equinor’s Empire Wind near Long Island, New York, have all been allowed to proceed with construction while their individual legal challenges to the stop work order play out.
The Department of the Interior attempted to pause all offshore wind construction in December, citing unspecified “national security risks identified by the Department of War.” The risks are apparently detailed in a classified report, and have been shared neither with the public nor with the offshore wind companies.
Vineyard Wind, a joint development between Avangrid Renewables and Copenhagen Infrastructure Partners, has been under construction since 2021, and is already 95% built. More than that, it’s sending power to Massachusetts customers, and will produce enough electricity to power up to 400,000 homes once it’s complete.
In court filings, the developer argued it was urgent the stop work order be lifted, as it would lose access to a key construction boat required to complete the project on March 31. The company is in the process of replacing defective blades on its last handful of turbines — a defect that was discovered after one of the blades broke in 2024, scattering shards of fiberglass into the ocean. Leaving those turbine towers standing without being able to install new blades created a safety hazard, the company said.
“If construction is not completed by that date, the partially completed wind turbines will be left in an unsafe condition and Vineyard Wind will incur a series of financial consequences that it likely could not survive,” the company wrote. The Trump administration submitted a reply denying there was any risk.
The only remaining wind farm still affected by the December pause on construction is Sunrise Wind, a 924-megawatt project being developed by Orsted and set to deliver power to New York State. A hearing for an injunction on that order is scheduled for February 2.
