The hiking community is usually the biggest supporter of conservation efforts. But sometimes the animal you’re conserving is scary.

Before I learned his name, I knew Joe Scott only as the Bear Guy.
“Oh, and he is an archetypal Bear Guy,” Andrea Wolf-Buck, the communications director of Conservation Northwest, a Washington state conservation nonprofit, wrote me in a follow-up email after the initial oblique introduction. “Joe does not disappoint!”
I was speaking with Wolf-Buck in the first place because, unlike Conservation Northwest, I am not someone who has a Bear Guy on speed dial. To be honest, all I knew about bears at that point boiled down to three things: 1) that I really do not want to get eaten by one, 2) something something something play dead?, and 3) that they brought out extremely strong opinions in the ever-lively Washington Hikers and Climbers Facebook group, a 263,000-member-strong private community prone to long debates over the ethics of geotagging photos, the progeny of large animal tracks, and, evidently, the proposed restoration of grizzly bears in North Cascades National Park on the Canadian border.
A typical comment thread on a post about the latter in recent years has looked something like this:
Stupid idea. Let them roam where they roam. If they end up migrating down here, then so be it.
We do not want grizzly bears in the North Cascades. Keep them where they are. This is a terrible idea.
I think Mother Earth approves. I’m excited about this!
I am a hiker and climber and would prefer not to be killed by a bear.
This is amazing conservation news and a project long in the making to bring them back to their habitat!
I love the N Cascades the way they are.
NO.
I, like many members of the overwhelmingly liberal, animal-loving, granola-munching hiking community in Washington state, am predisposed to anything and everything that has a conservation angle. The fisher restoration? Bring ‘em back! Gray wolves? A majestic animal and a beautiful success story! But guiltily, I’d felt a niggling sense of, well, understanding when fellow outdoor enthusiasts expressed nervousness about the grizzly proposal.
“[T]he thought of grizzlies in the North Cascades sends shivers down many a Northwest hiker’s spine,” Craig Romano, a local guidebook author in favor of the restoration project, has written. “And I know that many of my fellow hikers have no desire to hike in grizzly country — even less so to encourage these bears to return to some of their favorite hiking grounds.”

Though grizzlies (also called brown bears) once numbered in the thousands in the Pacific Northwest, their population was decimated by the Hudson Bay Company's fur operation in the mid 1800s. While hikers send pictures of cinnamon-colored (and deceptively named) black bears to the North Cascades park stewards in excitement every season, the last credible grizzly sighting in the area was in 1996. The grizzly bear — one of the most iconic symbols of the mountain west — is now believed to be functionally extirpated in the North Cascades.
Despite being a conservation horror story, this history has made modern Washington something of an arkoudaphobic hiker’s paradise. The state has all the rugged, breathtaking alpine beauty of places like Glacier National Park, Yellowstone, or British Columbia, but without the accompanying media reports of grizzly attacks. While Washington does have plenty of smaller black bears, they’re skittish and not considered to be much of a threat; precautions like bear spray and bear bells, all necessary in grizz’ country, are frequently dismissed by longtime locals as paranoid out-of-towner behavior. As Conservation Northwest’s Wolf-Buck sympathized with me on a call, “No Washingtonian who goes into the woods is really afraid of a black bear. We know what we’re supposed to do. Grizzly is a different story.”
The latest iteration of the on-again-off-again Washington state grizzly reintroduction process began in 2015 and found an unexpected bipartisan ally in President Donald Trump’s then-secretary of the Interior, Ryan Zinke. Opposition by the local ranching communities, taken up by Rep. Dan Newhouse (R-Wash.), sent Zinke backpedaling, and his successor, David Bernhardt, shut down the plan for good. Then last November, the National Park Service and U.S. Fish and Wildlife Service revived the effort to reintroduce the bears using the Endangered Species Act provision 10(j), intended to “relieve landowner concerns” by giving potential newcomer bears an experimental status of “threatened,” allowing for more management options and relaxing regulations. The public comment period ended in December; now everyone is waiting for the environmental impact statement, which is the next bureaucratic hurdle to clear.
In the meantime, you can count on a Bear Guy to tell it to you straight. “I think the number of human deaths at the claws of grizzly bears [in Yellowstone National Park] totals 11 since 1872,” Scott said. “So there’s your perspective.”
Scott’s real title is international program director of Conservation Northwest; in addition to working on the grizzly program in the North Cascades, he partners with teams in British Colombia on similar grizzly revitalization projects. The programs in B.C. are often led by First Nations groups, who are spiritually, culturally, and even geographically linked to the grizzly; on the southern side of the border, the Upper Skagit Indian Tribe has voiced support for the restoration efforts but did not reply to a request for comment by press time.
Scott had actually overestimated the fatalities he quoted to me: Since Yellowstone was founded, just eight people have been killed by grizzlies inside the park boundary (a ninth unsubstantiated fatality may have occurred in 1907 after someone supposedly poked a bear cub with an umbrella). The home of Old Faithful gets 4.8 million visitors a year; North Cascades, by contrast, is one of the least-visited National Parks, with just 30,154 visitors in 2022. Yellowstone estimates the odds of being injured by a grizzly within its borders are around 1 in 2.7 million visits; in theory, if that ratio held in Washington, it could take almost 90 years before there was even an injury.
Grizzlies are “not like little Tasmanian devils spinning around the landscape, striking hapless humans at random, or some nonsense like that,” Tom Smith, a bear biologist specializing in human-bear conflict, and who is not involved in the North Cascades restoration effort, told me. “There is always some predisposing factor, and the vast majority of those [attacks] … if the persons had done something proactive or differently, they wouldn’t have happened.”

The problem is, there is a lot of bad information out there about grizzlies, which is why people like me — outdoorsy, environmentally minded, sympathetic to conservation efforts — can get caught up in the what-ifs. Many such fallacies are repeated and amplified in those Facebook posts: that the translocation candidates would be other place’s “problem bears” (they wouldn’t be); that we don’t need more meat-eating carnivores roaming the mountains (Cascade grizzlies are heavy plant-eaters); and that we should wait for the bears to come back on their own (cut off from the North Cascades by roads and cities in B.C., they won’t). Even concerns about climate change’s impact on future bears can be assuaged; research shows habitats favorable to grizzlies are only likely to expand as the region warms, in part because bears eat many of the plants that are the first to spring up after wildfires.
Then there is the fact that we’re still years and years away from grizzlies being more than a few needles in a vast 9,800-square-mile haystack. The proposal on the table is to move just 25 bears into the mountains over a 10-year period, with the dream goal of the population reaching perhaps 200 after a century. “I will probably never see a grizzly in the wild in my lifetime in Washington state,” Wolf-Buck told me.
Despite the anxiety on social media, most people are also supportive of the proposal. A May 2016 poll commissioned by Defenders of Wildlife, another conservation nonprofit supporting the bear project, and conducted by Tulchin Research, found 79% of hikers, campers, hunters, and fishers in the state supported the effort. Among all voters, approval was one percentage point better.
Support dips to a still-strong 66% in the eastern, agricultural, and red parts of the state, including Okanogan County, which lies directly to the proposed reintroduction area’s east. “In the community that I am a part of, and in the circles that I typically spend my time in, people are staunchly opposed to having another predator to deal with,” Pam Lewison, a rancher and the director of the Center for Agriculture at the conservative Washington Policy Center think tank, told me, adding that “ultimately, the thought that these are majestic creatures who are more afraid of you than you are them is just not true.”
But grizzlies are “odds assessors,” according to Smith, the bear biologist, and there are simple ways for hikers to tilt the math in their favor. In addition to precautions recreationists should already be taking in black bear country — storing food in bear canisters and never in a tent — the “one thing I don’t see blazoned across every pamphlet that should be there is, you have no business going into bear country without a deterrent,” Smith told me. “I mean, you have no business.” For most people, that just means getting in the habit of carrying bear spray. And hike with friends: “The simplest thing that a person can do, that shows consistent positive results, is hike with two or more people,” Smith added. “I don’t have a single incident in North America where two people calmly stood their ground and the bear touched them.” (Oh, and all that stuff about playing dead? Don’t do that.)

Will there be a learning curve? Of course. But “just like the bears, we’re a highly adaptable species,” Scott told me, pointing out that “people will get used to it: They get used to carrying bear spray, they get used to storing their food in bins, they get used to making noise on a trail, and they get used to leashing their dogs. None of this is all that big of a deal.”
Then the Bear Guy said something that surprised me: that maybe we should be a little bit nervous outdoors. Maybe Washingtonians’ laxity is what is unnatural, the wildlife population long ago brought to a bloody heel by us. But is that actually what we want our state’s remaining wild lands to be — human playgrounds? “Some people want it, but I think most people don’t,” Scott said. “All the marketing for the outdoor crap and all this stuff — it’s all about adventure. Well, you want adventure? Here you go. Guaranteeing your safety is not adventure.”
There is still much work ahead: more studies; more research; more proposals; more letters to Congress; more outreach to the state’s ranchers, who are concerned about their livelihoods and the stresses on animals they care about; and, especially, more education of those who want to enjoy the beauty of Washington state but are a little bit uneasy about sharing that space with newcomers.
Which, to an extent, maybe we ought to be. As a wise Bear Guy once told me, “we might not necessarily be the boss out there, and that’s a good thing.”

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.
Noon Energy just completed a successful demonstration of its reversible solid-oxide fuel cell.
Whatever you think of as the most important topic in energy right now — whether it’s electricity affordability, grid resilience, or deep decarbonization — long-duration energy storage will be essential to achieving it. While standard lithium-ion batteries are great for smoothing out the ups and downs of wind and solar generation over shorter periods, we’ll systems that can store energy for days or even weeks to bridge prolonged shifts and fluctuations in weather patterns.
That’s why Form Energy made such a big splash. In 2021, the startup announced its plans to commercialize a 100-plus-hour iron-air battery that charges and discharges by converting iron into rust and back again The company’s CEO, Mateo Jaramillo, told The Wall Street Journal at the time that this was the “kind of battery you need to fully retire thermal assets like coal and natural gas power plants.” Form went on to raise a $240 million Series D that same year, and is now deploying its very first commercial batteries in Minnesota.
But it’s not the only player in the rarified space of ultra-long-duration energy storage. While so far competitor Noon Energy has gotten less attention and less funding, it was also raising money four years ago — a more humble $3 million seed round, followed by a $28 million Series A in early 2023. Like Form, it’s targeting a price of $20 per kilowatt-hour for its electricity, often considered the threshold at which this type of storage becomes economically viable and materially valuable for the grid.
Last week, Noon announced that it had completed a successful demonstration of its 100-plus-hour carbon-oxygen battery, partially funded with a grant from the California Energy Commission, which charges by breaking down CO2 and discharges by recombining it using a technology known as a reversible solid-oxide fuel cell. The system has three main components: a power block that contains the fuel cell stack, a charge tank, and a discharge tank. During charging, clean electricity flows through the power block, converting carbon dioxide from the discharge tank into solid carbon that gets stored in the charge tank. During discharge, the system recombines stored carbon with oxygen from the air to generate electricity and reform carbon dioxide.
Importantly, Noon’s system is designed to scale up cost-effectively. That’s baked into its architecture, which separates the energy storage tanks from the power generating unit. That makes it simple to increase the total amount of electricity stored independent of the power output, i.e. the rate at which that energy is delivered.
Most other batteries, including lithium-ion and Form’s iron-air system, store energy inside the battery cells themselves. Those same cells also deliver power; thus, increasing the energy capacity of the system requires adding more battery cells, which increases power whether it’s needed or not. Because lithium-ion cells are costly, this makes scaling these systems for multi-day energy storage completely uneconomical.
In concept, Noon’s ability to independently scale energy capacity is “similar to pumped hydro storage or a flow battery,” Chris Graves, the startup’s CEO, told me. “But in our case, many times higher energy density than those — 50 times higher than a flow battery, even more so than pumped hydro.” It’s also significantly more energy dense than Form’s battery, he said, likely making it cheaper to ship and install (although the dirt cheap cost of Form’s materials could offset this advantage.)
Noon’s system would be the first grid-scale deployment of reversible solid-oxide fuel cells specifically for long-duration energy storage. While the technology is well understood, historically reversible fuel cells have struggled to operate consistently and reliably, suffering from low round trip efficiency — meaning that much of the energy used to charge the battery is lost before it’s used — and high overall costs. Graves conceded Noon has implemented a “really unique twist” on this tech that’s allowed it to overcome these barriers and move toward commercialization, but that was as much as he would reveal.
Last week’s demonstration, however, is a big step toward validating this approach. “They’re one of the first ones to get to this stage,” Alexander Hogeveen Rutter, a manager at the climate tech accelerator Third Derivative, told me. “There’s certainly many other companies that are working on a variance of this,” he said, referring to reversible fuel cell systems overall. But none have done this much to show that the technology can be viable for long-duration storage.
One of Noon’s initial target markets is — surprise, surprise — data centers, where Graves said its system will complement lithium-ion batteries. “Lithium ion is very good for peak hours and fast response times, and our system is complementary in that it handles the bulk of the energy capacity,” Graves explained, saying that Noon could provide up to 98% of a system’s total energy storage needs, with lithium-ion delivering shorter streams of high power.
Graves expects that initial commercial deployments — projected to come online as soon as next year — will be behind-the-meter, meaning data centers or other large loads will draw power directly from Noon’s batteries rather than the grid. That stands in contrast to Form’s approach, which is building projects in tandem with utilities such as Great River Energy in Minnesota and PG&E in California.
Hogeveen Rutter, of Third Derivative, called Noon’s strategy “super logical” given the lengthy grid interconnection queue as well as the recent order from the Federal Energy Regulatory Commission intended to make it easier for data centers to co-locate with power plants. Essentially, he told me, FERC demanded a loosening of the reins. “If you’re a data center or any large load, you can go build whatever you want, and if you just don’t connect to the grid, that’s fine,” Rutter said. “Just don’t bother us, and we won’t bother you.”
Building behind-the-meter also solves a key challenge for ultra-long-duration storage — the fact that in most regions, renewables comprise too small a share of the grid to make long-duration energy storage critical for the system’s resilience. Because fossil fuels still meet the majority of the U.S.’s electricity needs, grids can typically handle a few days without sun or wind. In a world where renewables play a larger role, long-duration storage would be critical to bridging those gaps — we’re just not there yet. But when a battery is paired with an off-grid wind or solar plant, that effectively creates a microgrid with 100% renewables penetration, providing a raison d’être for the long-duration storage system.
“Utility costs are going up often because of transmission and distribution costs — mainly distribution — and there’s a crossover point where it becomes cheaper to just tell the utility to go pound sand and build your power plant,” Richard Swanson, the founder of SunPower and an independent board observer at Noon, told me. Data centers in some geographies might have already reached that juncture. “So I think you’re simply going to see it slowly become cost effective to self generate bigger and bigger sizes in more and more applications and in more and more locations over time.”
As renewables penetration on the grid rises and long-duration storage becomes an increasing necessity, Swanson expects we’ll see more batteries like Noon’s getting grid connected, where they’ll help to increase the grid’s capacity factor without the need to build more poles and wires. “We’re really talking about something that’s going to happen over the next century,” he told me.
Noon’s initial demo has been operational for months, cycling for thousands of hours and achieving discharge durations of over 200 hours. The company is now fundraising for its Series B round, while a larger demo, already built and backed by another California Energy Commission grant, is set to come online soon.
While Graves would not reveal the size of the pilot that’s wrapping up now, this subsequent demo is set to deliver up to 100 kilowatts of power at once while storing 10 megawatt-hours of energy, enough to operate at full power for 100 hours. Noon’s full-scale commercial system is designed to deliver the same 100-hour discharge duration while increasing the power output to 300 kilowatts and the energy storage capacity to 30 megawatts.
This standard commercial-scale unit will be shipping container-sized, making it simple to add capacity by deploying additional modules. Noon says it already has a large customer pipeline, though these agreements have yet to be announced. Those deals should come to light soon though, as Swanson says this technology represents the “missing link” for achieving full decarbonization of the electricity sector.
Or as Hogeveen Rutter put it, “When people talk about, I’m gonna get rid of all my fossil fuels by 2030 or 2035 — like the United Kingdom and California — well this is what you need to do that.”
On aluminum smelting, Korean nuclear, and a geoengineering database
Current conditions: Winter Storm Fern may have caused up to $115 billion in economic losses and triggered the longest stretch of subzero temperatures in New York City’s history • Temperatures across the American South plunged up to 30 degrees Fahrenheit below historical averages • South Africa’s Northern Cape is roasting in temperatures as high as 104 degrees.

President Donald Trump has been on quite a shopping spree since taking an equity stake in MP Materials, the only active rare earths miner in the U.S., in a deal Heatmap’s Matthew Zeitlin noted made former Biden administration officials “jealous.” The latest stake the administration has taken for the American taxpayer is in USA Rare Earth, a would-be miner that has focused its attention establishing a domestic manufacturing base for the rare earth-based magnets China dominates. On Monday, the Department of Commerce announced a deal to inject $1.6 billion into the company in exchange for shares. “USA Rare Earth’s heavy critical minerals project is essential to restoring U.S. critical mineral independence,” Secretary of Commerce Howard Lutnick said in a statement. “This investment ensures our supply chains are resilient and no longer reliant on foreign nations.” In a call with analysts Monday, USA Rare Earth CEO Barbara Humpton called the deal “a watershed moment in our work to secure and grow a resilient and independent rare earth value chain based in this country.”
After two years of searching for a site to build the United States’ first new aluminum smelter in half a century, Century Aluminum has abandoned its original plan and opted instead to go into business with a Dubai-based rival developing a plant in Oklahoma. Emirates Global Aluminum announced plans last year to construct a smelter near Tulsa. Under the new plan, Century Aluminum would take a 40% stake in the venture, with Emirates Global Aluminum holding the other 60%. At peak capacity, the smelter would produce 750,000 tons of aluminum per year, a volume The Wall Street Journal noted would make it the largest smelter in the U.S. Emirates Global Aluminum has not yet announced a long-term contract to power the facility. Century Aluminum’s original plan was to use 100% of its power from renewables or nuclear, Canary Media reported, and received $500 million from the Biden administration to support the project.
The federal Mine Safety and Health Administration has stopped publishing data tied to inspections of sites with repeated violations, E&E News reported. At a hearing before the House Education & the Workforce Subcommittee on Workforce Protections last week, Wayne Palmer, the assistant secretary of labor for mine safety and health, said the data would no longer be made public. “To the best of my knowledge, we do not publish those under the current administration,” Palmer said. He said the decision to not make public results of “targeted inspections” predated his time at the agency. The move comes as the Trump administration is pushing to ramp up mining in the U.S. to compete with China’s near monopoly over key metals such as rare earths, and lithium. As Heatmap’s Katie Brigham wrote in September, “everybody wants to invest in critical minerals.”

South Korea’s center-left Democratic Party has historically been staunchly anti-nuclear. So when the country’s nuclear regulator licensed a new plant earlier this month — its first under a new Democratic president — I counted it as a win for the industry. Now President Lee Jae-myung’s administration is going all in all on atomic energy. On Monday, NucNet reported that the state-owned Korea Hydro & Nuclear Power plans to open bidding for sites for two new large reactors. The site selection is set to take up to six months. The country then plans to begin construction in the early 2030s and bring the reactors online in 2037 and 2038. Kim Sung-whan, the country’s climate minister, said the Lee administration would stick to the nuclear buildout plan authored in February 2025 under former President Yoon Suk Yeol, a right-wing leader who strongly supported the atomic power industry before being ousted from power after attempting to declare martial law.
Reflective, a nonprofit group that bills itself as “aiming to radically accelerate the pace of sunlight reflection research,” launched its Uncertainty Database on Monday, with the aim of providing scientists, funders, and policymakers with “an initial foundation to create a transparent, prioritized, stage-gated” roadmap of different technologies to spray aerosols in the atmosphere to artificially cool the planet. “SAI research is currently fragmented and underpowered, with no shared view of which uncertainties actually matter for real-world decisions,” Dakota Gruener, the chief executive of Reflective, said in a statement. “We need a shared, strategic view of what we know, what we don’t, and where research can make the biggest difference. The Uncertainty Database helps the field prioritize the uncertainties and research that matter most for informed decisions about SAI.” The database comes as the push to research geoengineering technologies goes mainstream. As Heatmap’s Robinson Meyer reported in October, Stardust Solutions, a U.S. firm run by former Israeli government physicists, has already raised $60 million in private capital to commercialize technology that many climate activists and scientists still see as taboo to even study.
Often we hear of the carbon-absorbing potential of towering forest trees or fast-growing algae. But nary a word on the humble shrub. New research out of China suggests the bush deserves another look. An experiment in planting shrubs along the edges of western China’s Taklamakan Desert over the past four decades has not only kept desertification at bay, it’s made a dent in carbon emissions from the area. “This is not a rainforest,” King-Fai Li, a physicist at the University of California at Riverside, said in a statement. “It’s a shrubland like Southern California’s chaparral. But the fact that it’s drawing down CO2 at all, and doing it consistently, is something positive we can measure and verify from space.” The study provides a rare, long-term case study of desert greening, since this effort has endured for decades whereas one launched in the Sahara Desert by the United Nations crumbled.
