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.

Just look at Heatmap’s latest poll results.
A few times a year, Heatmap News surveys a few thousand Americans on the biggest questions driving the world of energy, environment, and climate change. We’ve spent the past few days writing up the results of our latest poll, which was in the field in late May and which I thought was particularly striking.
It’s worth taking a step back to look at the biggest results together, because the American view of data centers is essentially in free fall:
The upshot of these findings: The public‘s turn against artificial intelligence and AI infrastructure is real, widespread, and cross-partisan. It doesn't matter whether Americans started out tolerating data centers or having no opinion about them; they now seem to resent them en masse.

These results also suggest Americans see little distinction between data centers as energy users and data centers as the physical embodiment of AI and Big Tech. At Heatmap, we can be a wonky and energy-focused bunch, and so we tend to think about data centers primarily as large-scale electricity users. I think most approaches to come up with “data center policy” do the same. We know data centers are distinctive in some ways, of course — an AI data center might require more on-site batteries or power generation than, say, an EV factory — but fundamentally it is just another air polluter, large-scale power user, and light-industrial land user.
But the public does not see things this way. Americans understand data centers in the context of the much broader AI policy conversation about jobs, growth, alignment, and even human extinction. And so, I should add, do politicians: Senator Bernie Sanders has framed his data center moratorium proposal as a response to rapid AI development as much as anything having to do with energy affordability. For that reason, I wonder how long the distinction between these two policy conversations — data centers here, and AI policy over there — can persist.
One last thought on this topic: Is the public’s resentment starting to affect the AI boom overall? I think it might be. It was hard for me not to think of our polling results — or our analysis of canceled data center projects — as I read about a recent JPMorgan analysis that found America’s data center boom is “falling way behind schedule,” in the words of The Wall Street Journal. More than 60% of the data center capacity that is supposed to come online next year has yet to break ground, according to the bank; another 7% is “delayed.”
That’s partially due to equipment and labor shortages, but it also might be what a siting-and-permitting bottleneck would look like. Much like renewable developers or venture capitalists, data center developers work by picking a number of sites and trying to develop on all of them. If only a few sites work out, they’re still in the money. But if a falling share of projects are working out — if building anything, anywhere, is getting harder, everywhere — then it might materialize as delays.
Plus more of the week’s big money moves in critical minerals and electric vehicle charging.
Two of climate tech’s hottest sectors — fusion and critical minerals — dominated this week’s funding headlines. Helion led the pack with its $465 million Series G, helping to push the startup with the sector’s most aggressive commercialization timeline one step closer to putting power on the grid. The round follows last week’s news that German fusion startup Focused Energy secured a $240 million Series A, making it Europe’s most valuable fusion company.
Then there’s the critical minerals. Shortly after venture firm Gigascale Capital announced the close of its $250 million fund targeting the physical clean energy economy, it announced one of its first investments: Red Metals, a startup working to bring copper refining back to the U.S. Terra AI, which is using artificial intelligence to identify promising sites for mineral extraction, also landed fresh funding. Rounding out the week’s deals, EV charging and energy services company InCharge also raised a new round as it looks to expand into a broader suite of energy services.
Leading fusion startup Helion has nearly tripled its valuation with its latest $465 million Series G round, which aims to help the company deliver commercial fusion power this decade — the most ambitious timeline in the industry. Per the terms of the power purchase agreement Helion signed with Microsoft in 2023, the startup plans to turn on its first commercial reactor just two years from now. That’s far sooner than even its most precocious competitors, who aim to put fusion power on the grid by the 2030s at the earliest.
Joshua Kushner’s venture firm Thrive Capital led the round, which also included participation from new investors including Lux Capital and Alta Park Capital. Thrive now values the company at $15.5 billion.
“The investors that have joined this round, it’s institutional capital, some very marquee investors,” Helion’s CEO David Kirtley told me, explaining they were willing to back an unproven technology thanks to a series of recent milestones that Helion’s latest prototype reactor, Polaris, achieved. “Polaris earlier this year set records for temperature and fuel. We’ve also reduced a lot of the business risk on the regulatory front, the commercial front, and the actual supply chain, too.” In February, Polaris became the first reactor developed by a private fusion company to operate on deuterium-tritium fuel — the most common fuel in the industry — and to achieve a plasma temperature of 150 million degrees Celsius.
Helion differs from many of its peers pursuing more established reactor concepts such as tokamaks, stellarators, or laser-driven inertial confinement. Instead, Helion’s tech uses powerful magnets to collide and compress two fusion plasmas together, generating temperatures over 100 million degrees Celsius and triggering a fusion reaction. It then seeks to capture the electricity this reaction generates via electromagnetic induction — no steam turbine required — similar to the way regenerative braking works in an electric vehicle. If successful, the approach could enable smaller, more modular fusion reactors than conventional designs would.
While the company had originally aimed for Polaris to demonstrate electricity production from fusion in 2024, that date came and went with no new goal set. Kirtley told me that Helion remains on track to meet the terms of its agreement with Microsoft, however. The startup broke ground on its commercial reactor site last year in Malaga, Washington, where it already has access to a substation and grid interconnection from a dormant aluminum smelter. In addition to building out this facility, Helion also plans to use its new funding to boost production at its electrical component manufacturing plant in nearby Everett, which Kirtley said opened earlier this year.
As investors pour billions into artificial intelligence and the infrastructure supporting it, former Meta CTO Mike Schroepfer has raised an inaugural $250 million fund for his venture firm, Gigascale Capital, which is focused on the physical clean energy economy. This represents Gigascale’s first institutional fundraise since its founding in 2023; until now, the firm’s investments have come entirely out of Schroepfer’s own pocket.
The fund will target early-stage companies working in clean energy, grid infrastructure, critical minerals, and AI-enabled design and manufacturing, while reserving capital to continue backing its portfolio companies as they scale. Gigascale has already backed a number of big names in the space, including Commonwealth Fusion System, iron-air battery developer Form Energy, solid-state transformer company Heron Power, and clean baseload power startup Arbor Energy.
It’s also already begun investing out of this new fund, announcing this week that it led a $10 million seed round for critical minerals company Red Metals, which also included participation from JB Straubel, founder and CEO of the battery recycling company Redwood Materials. The company aims to help reshore copper refining in the U.S., and will use this fresh capital to support the development of a $70 million refining facility in Charleston, South Carolina. Red Metals says its process can convert copper scrap directly into a finished copper product, bypassing several of the costly and emissions-intensive intermediate steps typical of conventional refining.
The investment offers a window into the kinds of companies Schroepfer is most interested in — businesses that might lack the glamor of an AI startup but represent bipartisan opportunities to address core industrial bottlenecks. Copper, for example, is essential to all sorts of clean energy infrastructure, including transformers, power lines, and anode battery materials, but also critical for defense technologies such as radar systems and ammunition. Yet American copper production has been on the decline, with analysts projecting that the U.S. will face a refined copper shortage of over 2.5 million metric tons annually by 2035.
Sustainability-focused firm S2G Investments has been on a roll recently, announcing a $1 billion fund last month that aims to fill climate tech’s “missing middle” and backing Goshe Energy Storage with up to $40 million in strategic financing last week. Its latest move is leading a $46 million strategic investment round for InCharge Energy, an EV charging and distributed energy management company.
InCharge got its start installing and managing electric vehicle charging stations, and is now operating more than 30,000 assets across North America. Through its software platform and network of technicians, the company handles all monitoring, diagnostics, and on-the-ground repairs, taking on a charger’s full lifecycle to minimize downtime. With this new capital, InCharge plans to expand beyond EV charging and leverage its software and field service network in adjacent industries, including electrical infrastructure work such as panel upgrades and wiring repairs, as well as distributed energy resources like rooftop solar and battery storage systems.
“EV charging was the entry point, but our customers increasingly need help operating more complex energy infrastructure,” Rich Mohr, InCharge’s CEO said in a press release. “This investment from S2G accelerates our evolution into a full energy solutions provider and allows us to advance smarter technology and strengthen our service capabilities nationwide.”
It’s a hot week — nay a hot year, for critical minerals and subsurface exploration startups, especially for those pairing geology with artificial intelligence. AI-powered mineral exploration company KoBold Metals has raised about $1.2 billion to date, while geothermal exploration startup Zanskar has brought in about $220 million.
Now, another entrant is attracting investor attention. Terra AI has raised a $20 million Series A led by Khosla Ventures to help do it all — use AI to identify prospective sites for critical minerals mining, next-generation geothermal development, and permanent carbon sequestration.
Terra’s platform integrates vast geological and geophysical datasets to generate 3D subsurface models, as well as risk assessments that allow teams to evaluate a range of potential geologic scenarios. From there, the team can identify the best sites for exploratory drilling and thus reduce risk and uncertainty much sooner in the project’s lifecycle. The company even uses what it calls “geology reasoning agents” to help operators create their exploration plans, all with the goal of drastically reducing the notoriously long timeline between discovery and production, which can stretch to nearly two decades for many subsurface projects.
“Minerals sit at the center of every major technology and infrastructure transition, but today’s exploration results are not keeping pace with demand,” Terra’s CEO John Mern posted on LinkedIn. “Our mission is to advance the frontier of AI into the geosciences and help supply the metals and resources the next generation needs.”
One of the biggest fusion funding rounds of the year landed last week, and somehow much of the media — including me — missed it. German fusion startup Focused Energy raised a whopping $240 million Series A led by RWE, one of Germany’s largest energy companies. Yet unlike most deals of this magnitude, it arrived with little fanfare: No press release in my inbox nor a flood of headlines. So in the interest of making up for lost time, here are the details.
With this latest round, which also includes participation from the German Federal Agency for Breakthrough Innovation, the European Innovation Council Fund and Prime Movers Lab, Focused Energy has become Europe’s most valuable fusion company. Like several other leading players, including Inertia Enterprises and Pacific Fusion, Focused Energy relies on an approach known as inertial confinement fusion. This involves using powerful lasers to compress a tiny fuel target, creating the extreme pressures and temperatures required for a fusion reaction. To date, inertial confinement remains the only approach to have demonstrated net energy gain, with Lawrence Livermore National Lab achieving this milestone in 2022.
The startup plans to use this latest funding to build out a demonstration plant in the German state of Hesse, at a site where RWE formerly operated a nuclear fission plant. The company ultimately aims to build a commercial reactor by the mid-2030s.
Catching up with the American Council on Renewable Energy’s Ray Long.
Today’s chat is with Ray Long, CEO of the American Council on Renewable Energy. We first discussed the odds of permitting reform a year and a half ago, for one of the first Q&As in The Fight. Flash forward and we’re still in the same situation, but now also wrestling with added demand for electricity to power data centers. I wanted to talk again about whether he thought the rise of artificial intelligence would increase the odds of some federal deal happening any time soon. The result: a wide-reaching conversation about the future of the electric grid, the struggles to win community buy-in and the sclerotic nature of the U.S. Congress.
The following conversation was lightly edited for clarity.
Do you think the buildout of our energy grid is entwined with the rise of the nation’s data center buildout?
When you look at what we need over the next four years — 166 gigawatts, 15 times the peak load of New York City — that’s a lot of power to build. Roughly half of that is for data center and AI growth.
There are five things we can build in the next four years at scale to address that collective amount. First, it’s transmission — the transmission buildout will help to get a modern grid to enable power flow to where it’s needed in a much more effective way. That’s the first step because if we just build all that power, the current grid can’t handle it.
Second, there are four supply technologies that can be built: solar, batteries, wind, and natural gas. All four of those technologies, we know there’s enough equipment here in the U.S. available for purchase that we can build at volume. And I’ll say this — natural gas is only about 10% of all those gigawatts because of the availability of turbines from suppliers. You can’t get enough over the next four years. So when I talk about decarbonization, most of what is built to address this issue is zero-carbon resources, renewable energy resources.
If you were to compare the current conversation around data center development to the debate over developing renewable energy in the U.S. — or energy in general — do you see any similarities or differences?
There are always issues with permitting projects. Communities are always going to have concerns about what’s built in their backyards.
What’s new — and your polling shows this — is the level of concern communities have. But here’s the thing: Most of this can be overcome by developers going in, listening to what the needs of the communities are, then responding and through the permitting process addressing those concerns. You can’t do that 100% of the time. But my experience is, when you take that sort of approach, you can overcome a lot of it.
Most of the large data centers are actually doing the things I’m discussing — going in and saying, Look, we want to be grid interconnected because grid connection at the end of the day means the resources we’re bringing to bear are also going to make a stronger grid. Number two, it's investing in power generation sources like the ones I said — and those power sources will be on the grid, so they’ll solve for the increased power demands of a community.
Third, water. They should bring the water solutions. You’re seeing data centers coming in and saying it head on now, that they have closed-loop systems or whatever the solution is. At the end of the day, the communities they’re proposing these in have a real negotiating opportunity to make sure they’re holding the data center developers accountable to the needs of the community.
For a community to say we don’t want it here misses a real opportunity for those communities to get the power they need, the grid they need, and the ability to bring down energy costs.
How is the data center debate affecting permitting reform conversations in Washington, from your perspective?
Permitting reform in the U.S. at the state and federal level has been broken for years. The SunZia transmission project? It took 17 years to permit. Ribbon-cutting is in a week or two and there’s still litigation around it. From a business perspective, it’s just untenable, and it’s a miracle that the project is getting built. Developers need a chance to come in and have their project evaluated. Both the community and the developer should be able to get to a go or no-go in a couple of years on one of these projects.
How is data center growth affecting the permitting reform discussion? It’s a very hot issue right now. Right now I think in part because the data center issue is so huge — because we’ve only got four years to solve for the first really big tranche of power we need and prices across the board for electricity are escalating — this is coming to a head. The data center load is a part of the catalyst to get people talking about it [permitting reform].
Do you expect legislating in Congress on permitting reform this year? Anything beyond more conversation?
My hope is that we get a bill. A few weeks ago someone from the administration was quoted as saying they wanted a framework for a bill by the end of May, and it’s June now. We haven’t seen both sides or the administration coalesce around a final project yet.
We’re in a midterm election cycle. Typically it’s very difficult during these cycles to move bills like this. At the same time, with electricity prices increasing and the need to build more, to fix this, I’m very hopeful something will come together. And look at the Senate — you’ve got Republicans and the Democratic ranking members talking about this. It’s all good signs.
If everyone’s talking about energy and affordability during this election, isn’t that a good thing for action in the next Congress?
I’ll say this: You’re seeing the catalyst for it right now with prices rising, and almost every grid operator around the country has raised concerns about shortages at some point this year or next year. It’ll hopefully be enough to have policymakers do something about it this year.
