Climate shouldn’t be only a story for documentaries.

Paranormal: Caught on Camera is not the kind of television show you’d typically expect to read about in a research paper. Recent episodes include “Haunted Doll Bites Child” and “UFO Takes Off in Argentina”; a critic once described it as unsuitable for viewers who have developed “some powers of critical thought.” But credit where credit is due: Caught on Camera cites “climate change” as a possible cause of increased sightings of the Loch Ness monster.
This, alas, is the kind of meager victory the climate movement is often forced to celebrate.
According to research by USC Annenberg’s Norman Lear Center, there were just 1,228 mentions of “climate change” in the nearly 200,000 hours of unscripted TV that aired in the U.S. in the six months between September 2022 and February 2023. (Fifty-eight of those mentions were on “paranormal/mystery” programs, including Caught on Camera.) The situation is even worse for scripted film and TV: Between 2016 and 2020, just 0.6% of 37,453 scripts used the words “climate change” during their runtime. While there are notable exceptions — An Inconvenient Truth won the 2007 documentary Oscar, and The Day After Tomorrow and Don’t Look Up were mainstream hits — climate mostly remains off-screen even as nearly half the population says it has affected their lives.
Starting a Climate Film Festival, then, might seem foolish — because what would you even program? But New Yorkers are about to find out: The inaugural CFF will open Friday with a sold-out screening of the documentary Searching for Amani at the Explorer’s Club in Manhattan, with the festival’s 58 other films to be screened primarily at the Firehouse Cinema over Saturday and Sunday in a de facto kick-off to Climate Week. “Once we started digging, we found that there were an incredible number of these stories being told, but no one was really bringing them together under this rubric,” Alec Turnbull, who co-founded CFF with his wife, J. English Cook, told me.
The supply, however, is noticeably lopsided. CFF received “well over 300 submissions” during its open call for movies this past spring, according to Turnbull — enough that he and the volunteer screeners were able to winnow their broad interpretation of a “climate movie” from anything with “an environmental lens that didn’t have explicit climate themes” to movies specifically about climate.
In the end, though, unscripted documentary-style films and shorts came to dominate roughly 63% of the CFF slate. Only two of the program’s full-length features — the found-footage film Earth II and DreamWorks’ animated movie The Wild Robot — are fictional climate narratives.
This disparity might lead to the impression that there are too many climate documentaries in the world. (Seriously, how many more movies and shows can be made about regenerative farming?) While that isn’t the case — at least compared to something like the oversaturated true crime genre — documentary filmmaker might have more access to the subject than their peers in Hollywood because the medium has a “long history of addressing social issues,” Erica Lynn Rosenthal, the director of research at USC Annenberg’s Norman Lear Center, told me.
At least some mismatch is also likely due to “self-selection bias,” according to Turnbull. He told me that narrative filmmakers might not have submitted to something called the “Climate Film Festival” simply because they “don’t think about the work they’re doing as a climate story.” Another reason might just be endemic to film festivals. “Documentaries are really great for the festival circuit, for impact screenings, and for coupling with resources and workshops,” which boost their visibility even if they “don’t always make it to a broader audience” afterward, Tehya Jennett, whose short scripted horror film “Out of Plastic” is playing at CFF, told me.
According to the Norman Lear Center, however, nearly half of mainstream audiences said they want to see fictional stories that “include climate-related storylines” on screen. That’s far from trivial. “We know from decades of research that stories have the power to shift people’s hearts and minds and move them to action on a variety of topics, whether it’s health behavior or social issues,” Rosenthal said.
Sam Read, a CFF jury member and the executive director of the Sustainable Entertainment Alliance, an advocacy consortium that works to reduce the entertainment industry’s environmental impact, confirmed that the demand for climate narratives “currently outstrips the supply.” But he stressed to me that what makes a climate moment in a script doesn’t have to be something preachy, moralistic, alarmist, or even terribly overt, pointing to examples like the most recent season of Hacks, which included a bottle episode about climate change, and True Detective: Night Country, with its environmental and Indigenous plotlines.
“If you’re writing a sitcom and the mom is an office worker, could you make the mom a solar panel technician?” he asked, adding: “There are ways to both help people see what a clean energy future can look like while also exploring how this is affecting communities and how people are responding to it.”
Scripted examples, though, remain relatively rare. In the Norman Lear Center’s research, just 10% of the thousands of mentions of extreme weather in film and TV shows actually made any sort of link to global warming, perhaps because producers or executives worry that referencing climate change is political and might estrange half their audience. “The idea that [climate change] is going to alienate or turn off audiences is really an outdated perception,” Rosenthal said. Still, it’s even harder to push for experimentation and risk-taking when the film industry at large is struggling. And despite how it might look at CFF, it’s the documentarians who have been hit extra hard by the post-COVID turbulence in the movie world.
Of course, none of this is to say that documentaries are any less creative, ambitious, or worthy of being in a festival slate than their scripted counterparts. In fact, the Climate Film Festival’s centerpiece, The Here Now Project, is a documentary entirely composed of found footage of real people filming weather disasters during 2021. “Two people in the film actually say, ‘This is a horror movie,’” Greg Jacobs, who co-directed the documentary with Jon Siskel, told me.
Maybe it doesn’t really matter, then, in what exact form these stories are getting told: in a world with a changing climate, truth and fiction are equally strange.

The spinoff of Lawrence Livermore National Lab has a new 10-point plan to get onto the grid by the 2030s.
One of fusion energy’s newest startups, Inertia Enterprises, is betting that the fastest route to commercial fusion runs through one of the field’s oldest ideas. The company, which raised a $450 million Series A earlier this year, plans to build a power plant based on the laser-driven fusion system pioneered at Lawrence Livermore National Laboratory’s — the only tech yet to have produced more energy from a fusion reaction than it took to initiate it. Now, Inertia has shared its commercialization roadmap exclusively with Heatmap, detailing the 10 near-term capabilities it must demonstrate before this landmark experiment can become a grid-scale power plant by the mid-2030s.
The roadmap offers a route from the national lab’s impressive but commercially impractical fusion demonstrations to an economical power plant capable of producing electricity for the grid. At its core are a set of milestones — mostly aimed at developing cheap, mass-manufacturable components — that Inertia says it must clear before those individual systems can be integrated into a working plant. This road is not necessarily linear, however, as various teams will likely be working on many of these goals simultaneously.
At least the physics of Inertia’s approach are already proven, the startup’s CEO Jeff Lawson told me, pointing to the fusion experiments at Lawrence Livermore’s National Ignition Facility as a proof-of-concept. The lab’s demonstration of net energy gain caps more than six decades and $30 billion (in 2026 dollars) of U.S. fusion research. The remaining challenges, he argued, are all engineering-related, requiring “elbow grease, hard work, and smart people” rather than breakthroughs in fusion science.
"It seems to us like a startup or a commercial company of any variety should be focused on commercializing a proven scientific result, as opposed to actually trying to demonstrate the basic science to begin with," Lawson told me. Basic science, he argues, is better left to national labs and universities, where researchers can pursue "unbounded problems" that don’t align with the expectations and timelines of venture-backed startups.
Indeed, no fusion startup has yet achieved scientific breakeven, the milestone Lawrence Livermore first hit in 2022, and has since repeated numerous times. But leading players such as Commonwealth Fusion Systems and Helion Energy maintain that it’s only a matter of time before they validate the physics behind their own reactor designs, which they claim will be highly cost-competitive.
Lawson, on the other hand, readily acknowledged that Lawrence Livermore’s tech is uneconomical in its current form. His bet is simply that the more predictable path to a commercial reactor is to drive down the cost of the lab’s validated fusion approach, known as inertial confinement. This system relies on high-powered lasers firing at a millimeter-scale pellet of fusion fuel, compressing it to extreme temperatures and pressures until the atoms fuse. Today, the National Ignition Facility makes each individual fusion target by hand, a workable solution given that it only uses about a dozen per year.
That production model, however, isn’t remotely plausible for a grid-scale power plant. Because each fusion reaction lasts just a fraction of a billionth of a second, a commercial facility must fire its lasers at a fresh target about 10 times per second to generate continuous electricity — requiring the production of hundreds of millions of targets each year.
Scaling production to roughly a million pellets per day and making them inexpensive enough for commercial operation without compromising the strength or precision required for fusion ignition is central to Inertia’s roadmap. That includes goals five, seven, eight and nine — industrializing the manufacturing of the carbon shells that hold the fusion fuel, making the thin films that hold those carbon shells both durable and cheap, scaling up and automating fusion target assembly, and speeding up how fast targets are filled with the requisite deuterium-tritium fuel.
The other central focus of the roadmap is the laser system, which will ultimately consist of 1,000 individual units operating in concert to compress and heat the fusion fuel. Key priorities include reducing the system’s cost (goal two), dramatically increasing its firing cadence (goal three), and bolstering its durability to withstand high-intensity operations (goal four). Goal six also complements these efforts, calling for the development of a control system capable of tracking moving fusion targets to precisely align each laser shot.
Goals one and 10 bookend the journey with some broader milestones. The first focuses on increasing the fusion target’s energy gain — the ratio of fusion energy produced to laser energy delivered — to more than 25 times ignition. Today, the National Ignition Facility’s best-performing laser shot has yielded a gain of just over four times what it took to start the reaction. Goal 10 then zooms out to the ultimate objective: integrating all these technologies into a commercially viable power plant that can deliver either electricity or industrial heat to end customers.
To reach that point, Inertia has embarked on an industrial engineering hiring spree, recruiting folks with experience taking complex hardware systems from prototype to mass production, “not unlike the processes that are used in the semiconductor or consumer electronics world,” Lawson explained. The company has been making progress on its component development goals since the beginning of the year, he told me, and expects to announce the successful demonstration of a few of these milestones in the coming months. Lawson ultimately expects Inertia to complete the core components of its laser and target manufacturing systems by the middle of next year.
The team will spend the next two to three years integrating these individual pieces into two fully operational subsystems, a prototype laser system and a target manufacturing line. Around 2030, the company will begin combining those subsystems into a first-of-a-kind fusion power plant, which will also serve as the proving ground for the target chamber, tritium fuel breeding system, and power conversion system that turns fusion heat into electricity. By the middle of the next decade, Inertia aims to be generating power from this first plant, setting the stage for the company to build and connect additional grid-scale commercial power plants.
There are plenty of engineering trade-offs that the company will have to solve for. Take the decision around how to size the target chamber, for example. “If you make it bigger, your walls have an easier time and survive longer, but it’s more expensive. If you make it smaller, your walls have a tougher time because they’re closer to all the heat and energy that the fusion reaction is creating, but now your power plant costs less to build.”
But to Lawson, this represents exactly the type of problem Inertia was built to solve: complex engineering issues that come to the fore once scientists have demonstrated the fundamental physics are sound. He thinks other fusion companies may someday reach this stage, as well — though he’s unwilling to hazard a guess on exactly what approach or startup is best positioned to do so.
“There have been generations of scientists who’ve made their predictions about fusion energy and gotten it wrong,” he told me. “I’m not going to pretend to be smarter than them. All I’m here to say is, just knowing that one did work, we can commercialize it.”
