Once used by conservative media to promote climate skepticism, America’s favorite purveyors of pseudoscience are pivoting for the warming era.

Last week, the 2024 edition of The Old Farmer’s Almanac became the ninth bestselling nonfiction paperback in America. “Sales on Amazon … have never been so strong, and copies are also selling briskly at bookstore chains and indie bookstores,” The Washington Post’s book critic Ron Charles reported, going on to admit he is among the millions who are “hooked” on the almanac’s folksy advice, remedies, and, of course, its long-range forecasts.
This winter, The Old Farmer’s Almanac has told its readers to expect “a whole lot of cold” as well as “oodles of fluffy white throughout the season!” The Farmers’ Almanac — the primary competitor of Old Farmer’s, which postdates its founding by a quarter century — has a similar outlook. “The brrr is back!” it predicted, much like it did in the winter before this one (“shake, shiver, and shovel!) and the winter before that (“snowy comeback!).
In fact, for years now, conservative media has used The Old Farmer’s Almanac and The Farmers’ Almanac to promote climate skepticism, leveraging the periodicals’ reliable predictions of the “return” of winter and a “cooling” planet as a kind of gotcha against established science. And for years, the almanacs have played right into that agenda, conspicuously avoiding mention of the one long-range forecast we can accurately make: that the world is getting warmer due to the burning of fossil fuels.
But this is not a story of unrepentant climate deniers. Despite the right-on-cue predictions of a “freezing” winter, there are also encouraging signs the almanacs are starting to clean up their acts.
There is something both laudatory and a bit absurd about this, like if Punxsutawney Phil were suddenly to start consulting greenhouse gas emissions scenarios in addition to his shadow. When The Old Farmer’s Almanac debuted in 1793, the first accurate weather forecast was still 68 years away; almanacs at the time made their forecasts using a combination of folklore, weather proverbs, astronomy, and random guesswork.
Surprisingly, the two surviving Colonial almanacs largely use these same methods today. While The Old Farmer’s Almanac says it considers “all of the latest satellite data for making forecasts,” it also claims to incorporate a secret formula devised by its founder (a contemporary of George Washington) that is kept in a locked black box in the publication’s offices. The Farmers’ Almanac “firmly [denies] using any type of computer satellite tracking equipment” and instead makes its forecasts using its own proprietary formula, supposedly known only to the pseudonymous “Caleb Weatherbee.”
By modern weather modeling standards, such approaches amount to “astrology for weather,” Brian McNoldy, a senior research assistant at the University of Miami’s Rosenstiel School of Marine, Atmospheric, and Earth Science, told me. As he elaborated, “there is no real skill” on the part of the almanacs; needless to say, their secret formulas have not been peer-reviewed.
Indeed, actual farmers long ago abandoned almanacs in favor of agricultural weather stations, and the meteorological community generally agrees that long-term forecasts aren’t accurate more than 10 days out. The almanacs’ dubious claims of 80% accuracy are often chalked up to the same confirmation bias that is at play when you read your horoscope.
If the almanacs were solely in the business of telling you the most auspicious day to color your hair based on the moon’s sign, that would be harmless enough. But it’s the alarmist “brr is back!” headlines, not the eventual, weirder winter results, that get coverage this time of year — including, historically, in conservative media, which has used the almanacs’ predictions to drum up the cold spell fallacy that snowy winters supposedly disprove the world is warming.
“The famous Farmers’ Almanac is going to damper the mood of many man-made global warming alarmists,” Breitbart wrote, for example, in its coverage of the publication’s 2013 winter predictions. The same year, Townhall crowed that “The Farmers’ Almanac … is predicting a horribly cold winter as the Obama administration prepares to run around Congress to combat global warming.” Fox News ran a similarly celebratory segment and The Daily Caller recycled the whole argument in 2015.
Sometimes, the almanacs seemed to play along. In 2008, The Old Farmer’s Almanac published an article by Joseph D’Aleo, a “well-known climate change skeptic,” which proposed “another possible explanation for …. climate change” beyond human responsibility: sunspots. Once a common weather forecasting technique, the sunspot theory has since been seized by climate deniers to allege solar activity, not human emissions, is responsible for global temperature fluctuations.
“Studying these and other factors suggests that a cold, not warm, climate may be in our future,” D’Aleo went on under a headline that wondered, “Is Global Warming on the Wane?” The article was eventually even cited by Republican Senator James Inhofe in Congress against bills that would have addressed global warming, according to DeSmog.
When I asked for comment about this episode, though, The Old Farmer’s Almanac surprised me by seeming, well, embarrassed. “While it is true that The 2009 Old Farmer’s Almanac featured a story by Mr. D’Aleo, the Almanac’s editors do not agree with his opinions on climate change,” a spokesperson told me on behalf of the publication, adding that “many articles from previous editions of the Almanac make their way to our website; the fact that his article remained was an oversight. We have removed it.”
Sure enough, recent editions of The Old Farmer’s Almanac haven’t shied away from putting a name to warming trends. “Climate change is happening,” one orchardist is quoted as saying in an article from the 2023 Almanac, while a separate write-up on millet in the same issue states plainly that we’re living in “an era of climate change.” An item in the 2024 edition further frets that “climate change and rising temperatures” could imperil the diet of the Loch Ness Monster. (Before that disspirits you too much, the 2024 edition also explains that “average global temperatures [are steadily increasing] due to greenhouse gas emissions”).
The Farmers’ Almanac is more proudly anti-science than The Old Farmer’s Almanac — dismissing, as it does, that newfangled “computer satellite tracking equipment” — and its editor, Peter Geiger, declined to comment for this article. Previously, though, Geiger told Topic in 2018 that “I won’t get into the battle about global warming because I think it becomes a political debate,” though, of course, the omission is its own kind of commentary.
But if there was a time The Farmers’ Almanac could be evasive, it’s passed. Evidence of climate change has become so omnipresent and urgent that even the Fox News moderators at the Republican presidential debate have to ask about it. Sure enough, one of The Farmers’ Almanac’s 2022 articles notes that “climate change has made nature’s documented cycles unreliable,” although it avoids explaining why that change is happening. A 2023 piece online also quotes the United Nation’s definition of climate change while calling the topic “highly politicized” and therefore outside of the Almanac’s purview. But then, buried in an article published this spring, The Farmer’s Almanac admits that “when excess [greenhouse] gases are released through the burning of oil, coal, gas, and other fuels, the climate warms significantly.” Ah-ha.
Call it adaption: If either The Old Farmer’s Almanac or The Farmers’ Almanac plans to stick around for another century (at which point heat waves in California alone could be 10 to 14 degrees higher than they are now), the publications need to at least have some grounding in the warmer reality their readers will occupy. Ancient formulas will need to be dusted off, perennially “cold” winter forecasts quietly tweaked.
Doing so, in some ways, is anathema to such reluctant-to-change publications (even The Old Farmer’s Almanac’s cover has barely been altered since 1851). But if farmers’ almanacs have a central guiding tenet, it’s that there is a best time for everything.
And for talking frankly about climate change, it seems, they’ve finally realized such a time is now.

Tales from a day of “thoughtful dialogues on energy, climate change, and human lives” on Day 3 of New York Climate Week.
“I’m here because I love thoughtful dialogues on energy, climate change, and human lives,” Energy Secretary Chris Wright told my colleague Robinson Meyer this afternoon. “That’s been a passion my whole life, and nothing will change that.”
It’s our passion too — and was a defining theme of Heatmap House on Wednesday at New York Climate Week, with 27 sessions across topics including clean energy development, U.S. climate policy, the future of mobility, climate tech, and reindustrialization. From Wright backpedaling on President Trump’s embrace of a diesel export ban to former Vice President Al Gore asserting that 2026 might mark “the positive tipping point on climate,” it was a full day of news, contrarian opinions, juicy predictions, and lots and lots of coffee (consumed by yours truly).
Early in the day, Carlos Araque, the CEO and co-founder of Quaise, an advanced geothermal company, started things off by addressing the elephant in the room: potentially imminent movement on permitting reform. “It’s always easy to be picky and want for more,” he acknowledged, although he added that “my ask has always been — as far back as 2018 — if you can do for geothermal what you do for oil as in terms of regulatory permitting exclusions, then you’re moving 90% of the way to the goal. So that’s happening — that’s slowly and surely happening.”

New Jersey Governor Mikie Sherrill also spoke about permitting reform at a local scale. “You cannot simply say to people, ‘Sorry, your bills are just going to keep skyrocketing,’” she stressed. “That is not the answer, which is why we’ve acted so aggressively. I approved 18 solar and battery storage projects in the first six months [of my term]. We knew the federal credits were going to run out if we did not get that done, so that’s why we had to take on permitting reform right away to make sure we were growing that.”
And while Jane Flegal, the principal at Flegal Energy Advisors, didn’t have any secret insight into the potential deal, she broke down her predictions into three buckets: reforms to conventional environmental statutes such as the National Environmental Policy Act, the Clean Water Act, and the National Historic Preservation Act; transmission, “which, no one knows what’s in there, but we all know what was in the Manchin deal, and I think we can and should expect something at least that ambitious;” and permitting certainty, which would constrain executive power to cancel permits after they’ve been issued.
Chris Hayes, the host of All In with Chris Hayes on MS NOW and a former climate reporter, took the stage just after Gore, who marked the 20-year anniversary of his Academy Award-winning documentary An Inconvenient Truth. Like Gore, Hayes was in a reflective mood. “I think to some degree, we’re kind of moving forward in this understanding that all of us are implicated in the system that’s going to change very slowly over time,” he said, calling it one of the lessons of the past 20 years. “But I think there was a high-water mark of consumer activism that is sort of gone.”
Then, of course, there was Wright. The energy secretary — whom climate insiders have described to us as the biggest climate villain in the Trump administration after Trump himself — talked to Rob about as many fuels as they could cover. Wind: “There have been very spirited dialogues in the administration about this. I do believe a successful permitting reform thing changes the playing field for anything you want to build in this country, including wind.” Nuclear: “Our thing is just to try to get it back on its feet and get out of the way.” Natural gas: “Gas in my lifetime is going to be the American energy superpower for sure, but you never want all your eggs in one basket.” Batteries: “I’m all in.” And EVs: “Should we have the broader America subsidizing, you know, the habits of wealthy people? I don’t think we should.”
Electric vehicles also came up in our mobility session, of course, along with other forms of mobility including ferries, subways, and rail. “It’s not something we talk about very much in the U.S.,” Laura Fox, the co-founder and managing partner of Streetlife Ventures, told me, adding that “we have a really great rail freight network that is underutilized and that typically saves shippers 30% to 40% when they’re shipping goods in the current environment.” (Representative Mike Levin of California also shared that if he could only connect two places in his proposed giant high-performance rail system, “I’d like to see the line between Los Angeles and San Diego solidified.”)
The evening wrapped with a focus on reindustrialization. Tom Steyer, the co-executive chair of Galvanize Solutions, told us he’s doing fine after his unsuccessful bid for California governor. (Nothing a trip to Tahoe with the family couldn’t cure.) He also shared that the climate movement may have lessons for the modern movement opposing AI and data centers. The world’s richest companies can’t just “come in and take people’s water, especially at a time when people are so water insecure,” he stressed. “How could that possibly be right?”
AI — and water — also came up in conversation with Emilio Tenuta, the senior vice president and chief sustainability officer of Ecolab, which provides industrial and commercial water and hygiene solutions. (Ecolab also sponsored our reindustrialization section.) He argued that “what we really need to focus on is the Water Efficiency Index” when evaluating, for example, semiconductor fabrication plants, because it contextualizes water use in more absolute terms than traditional metrics.
Page Crahan, general manager of Tapestry, an Alphabet X moonshot project that uses AI to develop a model of the grid’s electricity network, zeroed in on how best to use artificial intelligence. “We had 10 years to build what it took us 110 years to build globally” in order to meet anticipated energy demand, she told my colleague Jael Holzman. “And that was in 2023, before data centers.” For “computationally intensive challenges, data-heavy challenges, and certainly running simulations and insights for a system this size,” AI is a good use case, she said.
Tapestry is using its models in partnership with PJM Interconnection (as we’ve covered here at Heatmap) — and speaking of PJM, its executive director of strategic policy and external affairs, Asim Haque, spoke to my colleague Matthew Zeitlin next. “If you do not bring your own new capacity, we are going to curtail you before we curtail your average residential consumer for sure,” he said, adding, “this is a concept that is pending in front of the FERC right now. We can talk about carrots. We can talk about sticks. I don’t know which one this is. I think from the data center perspective, it’s likely a stick.”
Josh Parker, the head of sustainability at Nvidia, rounded the day out on a positive note. “The good news is, we are very quickly unlocking new capacity with clean energy,” he said, including developing new clean energy technologies like advanced fission and geothermal. “All of these technologies are benefiting from AI, and so that, coupled with the fact that data center operators with AI factories generally are some of the largest consumers of clean energy and are still are looking for all the clean energy they can, leads me to believe — and I think this is the most credible forecast — that very soon we’re going to see all of that convert over to clean as soon as we can get through the supply constraints that we’re currently in.”
If you were with us in person, thank you again. You’re what made our event one to remember. And if you weren’t able to join us this year — we hope to see you in 2027.
But wait! Before I send you on your way, you can find all of our coverage of the day below along with some additional quotes from some of my favorite conversations:
The Commonwealth Fusion Systems CEO made his case at Heatmap House.
Without billions in new federal investment the United States may lose its pole position in the global race to be the first nuclear fusion superpower, Commonwealth Fusion Systems CEO Bob Mumgaard told attendees at Heatmap House in New York City.
When asked onstage whether Commonwealth Fusion could still develop its fusion aspirations at scale without U.S. government financing, Mumgaard said: “I think so – it’s a question of the timing and the place.” Then he suggested that the company — and the industry — might go elsewhere if the country doesn’t put more capital into the growing sector. “There are offers on the table to build nuclear fission power plants not in the United States, so we can do that.”
You’d be forgiven if you thought Commonwealth and nuclear fusion was already doing well. The Massachusetts-based pioneer in fusion technologies raised $1 billion in new investment just a couple months ago. Generally speaking, innovation in nuclear power is incredibly popular in Congress, which has an influential bipartisan Fusion Energy Caucus. Commonwealth has received public support from the Trump administration’s Energy Department, as has one of the Heatmap House sponsors, Inertia.
But we’re talking about nuclear fusion, a still-futuristic form of energy generation seeking to harness the power of stars exploding in contained environments. It’s an insanely promising tech moonshot.
Mumgaard said the company is aiming for its tech to provide electrons onto the grid by the 2030s. He also said a Fusion Industry Association request to Congress and the Trump administration for $10 billion of investment might be what’s needed for that power to be American first.
“We debated that [amount] with the industry association, and you have to say what gets the job done. It’s a disservice to lowball what’s needed,” he told my colleague Katie Brigham. “This is a very important thing. It’s an entirely new industry. Let’s treat it as such.”
He added his view that U.S. fusion development is essentially an energy security maneuver, and that competition with China on fusion should be seen as parallel to the race for dominance in artificial intelligence.
“Think about what it means in a technological race. Power is the thing that powers the next economy, right?” Mumgaard said. “All the geostrategic strife we have right now is about power in the form of natural resources. Who has them? What are they? What boats are they on through what body of water? Fusion takes all of that off the table.”
Representative Mike Levin, It’s Electric, Rivian, and more showed up for the mobility session at Heatmap House.
On the surface, the climate case for electric vehicles is simple: Battery-powered cars can eliminate our need to burn dirty gasoline and diesel, and as more renewables come onto the grid, they’ll only run more and more cleanly. But the benefits that can be gained from electrifying the vehicle fleet run far deeper, a case that a variety of speakers made at Heatmap House on Wednesday as part of New York Climate Week.
Andrew Peterman, director of advanced energy solutions at the EV maker Rivian, explained how electric vehicles are becoming a multi-tiered grid solution. Rivian itself is cooperating with drivers and utilities to create automatic smart charging so that EVs can charge when energy is abundant and inexpensive, saving the user money — in some cases as much as $1,000 per year — and easing strain on the grid. Doing so helps to keep electricity prices down, which is good for the country and for the bottom line of an electric vehicle maker.
“Our ability to sell and give people value out of an electric vehicle can only be enabled if we transform the grid to be able to be affordable, reliable, and cleaner for everyone,” Peterman told Heatmap deputy editor Jillian Goodman. “We need to use our role in the energy system to enable customers to get more value out of the grid. So everything we do is about grid transformation to enable electric vehicles to have an even stronger and stronger value proposition. When we bring down electricity costs, that brings down the total cost of ownership for our vehicle owners.”
Of course, energy can go in the other direction, too. Now that millions of EVs are on the road, the multitude of kilowatt-hours stored in EV batteries can be a grid asset. That goes for vehicle-to-grid integration, where EVs can discharge energy to help balance the grid when they’re not driving. But it’s an especially compelling proposition when those batteries get older and are no longer optimal for powering vehicles. Rivian is working with partners such as Redwood Materials to recycle old EV batteries and to repurpose some as grid storage. The same is true at Waymo, whose fleet of autonomous, only-electric rideshare vehicles have racked up hundreds of thousands of miles in some cases.
“Our fleets are sometimes outlasting our batteries where they still work, but they’re just not optimal for the ride-hailing fleet,” Waymo head of environment and sustainability Adam Lenz told Nico Lauricella, Heatmap’s CEO and editor in chief. “So we’re taking those batteries out, refreshing them, and then there’s still a lot of life left on this battery. We’re working with a partner that’s based out of L.A. County where we provide service and they’re deploying those batteries to support front of the meter grid storage.” (Waymo is also a sponsor of Heatmap House.)
It’s clear that the rideshare economy will be dominated by electric vehicles, and Lenz argued that this fact helps extend the climate benefits of electrification and autonomy to people who don’t want to drive or have been priced out by the upfront costs of an EV. The promise that self-driving cars will ultimately be much safer compared to those driven by fallible humans makes it safer to walk or bike, the most sustainable transportation methods. Waymo recently introduced a partnership with Visa to give San Francisco Bay Area riders a $2.85 Waymo account credit (the price of a bus ride in S.F.) when they combine a rideshare trip with a train or bus linkup to create a mulit-modal journey — a roundabout way to create “free” buses.
Across the country, EV charging could help give New York City not only cleaner skies but also improved grid management. The city’s Green Ride Initiative is meant to have New York’s taxi and rideshare trips be majority-electric by 2030, yet NYC has been a charging desert compared to other dense cities like London. Tiya Gordon, co-founder and COO of charging company it’s electric, came to Heatmap House to discuss her company’s recent win of a contract to install 700 new street chargers in New York, which has only 88 today.
It’s not just how many chargers are going in, she said, but where — the majority will go into neighborhoods in Brooklyn and Queens where rideshare drivers live and park their cars overnight. Albert Gore, executive director of the Zero Emission Transportation Association, added: “It makes a lot of sense also when you think about the impact to the grid. If you are directing a lot of that charging at night, particularly for these high mileage use cases, that actually puts downward pressure on electricity rates. EVs are a very, very flexible load.”
