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.

The data center boom is everywhere you look in U.S. economic and emissions data.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
It isn’t exactly a new thought, but I’ve been struck recently by how many trends in America’s economic and environmental data are fundamentally about the data center boom and the return of electricity demand:
First, the Energy Information Administration reported this week that U.S. emissions grew by more than 2% last year, driven by surging electricity demand and an increase in coal-fired generation. What caused that higher power demand? New factories and data centers — as well as record summertime cooling demand.
Second, many of the new factories driving that higher power demand are themselves producing goods that are … let’s say … data center-adjacent. There are the enormous new semiconductor fabs, of course. But Ford and General Motors have also set up new production lines (or repurposed old ones) to manufacture grid-scale batteries to meet power demand.
Third, take a look at the recent U.S. spending on private non-residential construction — in other words, everything American companies are building that is not houses, condos, or apartments.
The construction industry’s spent almost $60 billion on data centers over the past year, which is more than it spent on all other office buildings combined (and more than it spent building warehouses, too). Just a handful of categories — data centers, power plants, electricity infrastructure, and certain kinds of electronics manufacturing — now make up a third of all U.S. private non-residential construction investment. They’ve never made up such a large share of construction spending since data collection began in 2014.
As The New York Times recently noted, the American economy is unusually dependent on the American stock market right now — and the stock market is unusually dependent on artificial intelligence. This week, investors started to balk at the enormous spending hyperscalers are planning to keep building out the AI boom; Alphabet’s shares dropped 8% this week after it boosted its planned 2026 capital expenditure and signaled 2027 will be even bigger. If the data center boom started to slow down in earnest, then more than just that budget will change.
Speaking of which, my colleague Emily Pontecorvo wrote earlier this week about how many businesses are struggling to even estimate their carbon emissions from artificial intelligence. The carbon accounting startup Watershed recently unveiled a new formula to help companies get a sense of their AI-related emissions.
But even that formula is still limited by the amount of data hyperscalers publish — and they don’t publish that much. Google, for instance, is the only AI company that has (laudably) provided estimates of its emissions on a per-prompt basis. Yet no company has published its per-token emissions, or how emissions sync up with particular models or regions.
So Emily asked Google: Why aren’t you — or any other model provider — disclosing this kind of data yet?
The tech company didn’t get back to us until after we’d published Emily’s story. But its response was interesting enough that I wanted to quote some of it here.
The problem is “industry consensus,” Cooper Elsworth, a Google spokesperson, told us. “There is currently very little consensus on how to comprehensively and fairly measure the serving environmental impact of generative AI (such as text generation),” he wrote. “Without standardized, ‘apples-to-apples’ frameworks, it is difficult to compare different providers accurately.”
That’s partly because energy use — and emissions data — can vary from site to site and depend on “custom-built hardware, software compilers, and advanced inference techniques.” And he claimed Google doesn’t always have the measurement hardware in place to provide such specific estimates: “Providing precise, repeatable data requires highly advanced measurement infrastructure,” he said. “For example, software-based energy monitoring tools often suffer from sampling biases. For our study, we had to step away from top-down averages and directly measure actual energy at the physical power supply unit (PSU) level across our deployed fleet. Not all providers have the telemetry or data sets required to benchmark their operations at this level of granularity.”
Read Emily’s story to understand the other reasons why estimating — or even “guesstimating” — AI-related carbon emissions is so challenging.
A conversation with Emma Uridge of the Kansas Health Institute.
This week’s conversation is with Emma Uridge, analyst with the Kansas Health Institute. Uridge spent copious hours analyzing state and local laws on data center development to best understand how policymakers are responding to the potential environmental public health impacts of large AI infrastructure, including power and water. The report, which came out this week, also goes in depth into those health impacts. I reached out to her to discuss what she sees as must-watch territory for our readers on this emerging policy arena.
Our conversation was lightly edited for clarity.
What is actually being done on policy when it comes to data centers — beyond moratoria of course?
So first I’d like to just talk about the point of moratoria. It’s helpful to talk about how these policies emerge in the first place. One area where moratoria are helpful is when a data center is proposed but the county has no approach for how they’d like to potentially regulate them. That’s temporary, most of the time. It lets local governments conduct research on the various impacts and also negotiate community benefits, ones that can mitigate any potential negative impacts — like Lancaster Pennsylvania, which instituted a community benefit agreement that maximized the potential benefits of development while mitigating what large data centers can do. That agreement looked at capping municipal water use at 20,000 gallons per day and requiring 100% clean energy. It had financial penalties for non-compliance. The company also committed $20 million to their local economic development and clean energy fund. There are ways to negotiate with developers.
We also see amendments to existing zoning. Data center proposals are increasingly popping up in rural areas, many of which are unzoned, so there’s no way a county can negotiate unless there’s a moratorium in place.
Other policy solutions include different performance standards or requiring on-site renewable energy, like what Jefferson County, Missouri, looked at. Also setback requirements, mandatory noise buffers, ending by-right zoning.
Where are local governments getting ideas for regulating data centers?
A lot of the technical information comes from developers. That can in cases be seen as a biased source of information. I wouldn’t say there’s a dedicated group providing assistance to local governments when a project is proposed — which is a similar story to wind industry development, where we have only a handful of consultants who provide technical advice. It can be really helpful to get a multi-disciplinary approach to hearing information. It can be helpful to have the utility commission, public health folks, those in academia, as well as the developer.
As of right now, especially in rural areas, local governments have a hard task of balancing pushback while getting the most accurate, evidence-based, neutral information to make decisions. That balance can be contentious.
What is the federal government doing on data center policy? How is the Trump administration approaching it?
A few things there. In the early days, the drive was for AI expansion and to be competitive with foreign adversaries. Now due to the amount of public pushback in red and blue localities and a more cautious approach.
I’m not seeing a lot of actual policy movement at this time.
I know the EPA is looking at the chemicals used in cooling data centers because when that water is cycled through the system, some of it is discharged into the water system, so they’re looking at the Toxic Substances and Control Act for monitoring that.
How much of an impact does this minimal federal role have on industry behavior?
Y’know, this isn’t specific to data centers. This is true for all kinds of large-scale development: there’s a need to require some sort of federal monitoring and regulation.
That’s where I see an emerging role for public health. At the federal level, there could be policy movement towards requiring some sort of environmental monitoring at data centers to make sure they’re operating responsibility. Looking at specific water use relative to water availability and what happens when there’s a time of severe, persistent drought. With air quality too — we’ve seen areas where the grid isn’t as reliable so their diesel generators are kicking on more and affecting air quality for residents.
We’re just not seeing all of that right now. We need corporate disclosure.
What do you see as the most important public health impacts from data center development?
It varies by localities. The most discussed obviously is water usage. One thing I’d note about my conversations with folks enthusiastic around emerging tech is, there are still questions that need to be asked about the capacity of localities to support a data center. Like a small town in Kansas may only be using 40% of their water for their utility needs. If a data center came online, how much of that water goes to the data center?
One area underexplored within the public health discipline is energy poverty and energy security. The ability of a household to meet the needs of everything energy provides in our lives. It’s known we have an aging electric grid but we’re not talking enough about large-scale blackouts when the grid is not sufficient to support some of these new data centers.
Plus more of the week’s big development fights.
1. Laramie County, Wyoming — Meta is fighting the fine it received in the Cheyenne data center water pollution controversy, and the conflict between the tech giant and the city’s small board of public utilities is continuing to spill out into the public.
2. Niagara County, New York — This county just rejected a solar project’s highway work permits in a show of retaliation against the state’s Office of Renewable Energy Siting.
3. Barron County, Wisconsin — The anti-solar protest is the new campaign stop in deep red Wisconsin.
4. Chesapeake, Virginia — A large battery storage project on the Virginia coastline is on the rocks amidst rampant local opposition.
5. Lewis County, West Virginia — West Virginia is now a key battleground in the fight over transmission, as a line spanning all of West Virginia and Maryland — and cutting through Data Center Alley in Virginia — causes compounding consternation.
