Ice melt is creating many geopolitical dangers, thanks largely to a familiar foe.

The Arctic is becoming dangerously destabilized.
This is true in a literal sense. The north’s precipitous loss in glacial ice sheets, permafrost, and sea ice will have global ripple effects. Should the “Earth’s air conditioner” become perennially iceless, as scientists fear could happen as early as 2050, the fallout has the power to trigger worst-case scenarios around the world: Sea levels could rise in New York City, monsoon rains could swamp Lagos, Nigeria, and precious forest cover in Puerto Maldonado, Peru, could dwindle to nubs. Each glacier that collapses is another tick of the time-bomb.
But it’s also true in a more metaphorical sense: Arctic ice melt is creating many geopolitical dangers, thanks largely to a familiar foe: Russia.
The Kremlin controls 50 percent of the Arctic coastline. But isolated from the other countries encircling the North Pole due to its war of aggression in Ukraine, Russia has retreated from any sort of Arctic cooperation. That has left experts fearful not only of scientists’ ability to stay on top of the impacts of climate change, but also that the warming region might give Russian President Vladimir Putin a pretext to break more international rules.
For the last 15 years, Russia has jockeyed for Arctic control — from aggressively building its military capabilities, to scaling up its shipping capacity, to even unlawfully planting a flag along the North Pole seabed and claiming the land as its own. But it was still hemmed in by the Arctic’s web of laws and accords.
These laws, unfortunately, are quite vulnerable to ice melt.
Maritime claims, upheld by entities like the International Maritime Organization, for example, are one way for states to protest rule-breaking in the region. But melting sea ice has opened up previously frozen zones, threatening to undermine laws like Article 234 of the United Nations Convention on the Law of the Sea, which gives coastal states special rights to ice covered areas. “If the ice melts, do you still have that legal basis?” said Rebecca Pincus, the director of the Polar Institute at the Wilson Center.
Valuable shipping lanes are also emerging in the north, encouraging Russia to further engage in a two-fold strategy: mass resource extraction to underpin its national wealth and taking “the most extreme position possible on its right to control all foreign navigation through the internal waters of the [Northern Sea Route],” as Cornell Overfield wrote recently in Foreign Policy. However, this state of affairs might not last long. “As sea ice continues to retreat in the Arctic, it will become possible for ships to navigate outside of the Russian zone through the central Arctic Ocean and bypass the Russian coastline entirely,” Pincus said. “That will shift the balance of the, I guess you could say, ‘power’ to a certain extent.”
These central Arctic Ocean shipping routes will not be open for decades and pose a number of operational challenges along the way, she explained. But when they do, it would allow ships to navigate outside Russian waters, reducing the potency of Russia’s de facto control along the Northern Sea Route, further isolating a country that sees the icy region as a part of its power projection.
Meanwhile, Russia is essentially alone among its neighbors.
Mathieu Boulègue, a consulting fellow in the Russia and Eurasia Programme at Chatham House, told me a bifurcation is emerging in the north, where a singled-out Russia has recused itself from the Nordic-North American camp — a once-staid Arctic 8 now made into an awkward, asterisked Arctic 7. With Finland having joined NATO this month, and Sweden close behind, Russia might see itself as not just alone, but surrounded. Experts fear that spells trouble.
“More human activity and more military activity will lead to more accidents, more incidents, more miscalculation, and therefore more tension,” said Boulègue. “Now that the signs are on the wall, we can't really ignore them anymore.”
The United States and other countries rimming the Arctic are carefully initiating exploratory military exercises in the region to see how they can navigate safely and effectively in newly-melted territories. Because of how remote the Arctic is, accidents and emergencies are exponentially harder and more expensive to triage. The latest U.S. Arctic strategy promises to increase its military presence there, too, in order to keep pace with the Russian military presence. But experts warn that neither technology nor policy in a territorially hostile area could keep up with the speed of these melting passages. Indeed, they say it would take the West at least 10 years to catch up with Russia’s military in the region. This opens up dangers for Russia to do just about anything it’d like to, including seizing new territory and setting up military bases in contested areas.
“We're seeing some pretty aggressive, unprofessional, and unsafe behavior by the Russian military in regards to American military assets [in the Arctic],” said the Wilson Center’s Pincus. “Think about that level of risk-taking and aggression on the part of the Russian military and now extrapolate that to, for example, a naval exercise that is contesting Russian claims to waters in the Arctic. That gives me pause and argues for great care.”
Beyond the threat of Russia’s mounting military capabilities in the region, Arctic cooperation has also suffered more generally from Russia’s absence. The Arctic Council is a Nobel Prize-nominated diplomatic forum that convenes the Arctic 8, six non-Arctic states, and a cadre of non-governmental observers which include Arctic Indigenous communities. This preeminent intergovernmental venue had to suspend all of its programming after the start of the war in Ukraine. It has only picked up projects since June of last year that do not require cooperation with Russia. Norway is set to assume the chair of this forum come May, but will have to tread delicately if it means to keep Russia within the Council’s orbit.
“The accession by Finland and Sweden to NATO will strengthen security and stability in Northern Europe, including in the Arctic. While security related aspects will understandably become more important, we must ensure that we do not lose sight of the broader issues in Arctic cooperation,” said Finnish Ambassadors Petteri Vuorimäki and Anne Mutanen in a statement to Heatmap.
These so-called broader issues not only impact high-level powers in the Arctic, but also those who are native to the region. Today, six Arctic Indigenous NGOs hold a non-voting status in the Arctic Council, making it one of the world’s only multilateral forums where national government officials sit at the same table as Native leaders.
Many of the six Arctic Indigenous communities who participate in the Arctic Council have ancestral lands that extend into Russia. Leaders among the Indigenous Saami people, for instance, fear that while Arctic states are busy ironing out tension spurred by Russia and its war, their priorities — from phasing out ecologically harmful heavy fuel oil, to prioritizing climate-resilient infrastructure, to recognizing land rights agreements which enable important climate science research, to triaging the potential displacement of Indigenous communities amid coastal erosion and sea ice melt — may take a back seat. “It's not said straight; it's a feeling underlying there that they have more important things to deal with,” said Gunn Britt-Retter, head of the Arctic Environment Unit of the Saami Council, which represents the Saami people spread across Norway, Sweden, Finland, and parts of Russia.
And then there’s another way Russian isolation is punishing the world: science. The world’s leading scientists desperately need access to this corner of the world to establish what they call a “ground truthing,” — basically an up-close understanding of what they’re only seeing now via satellites.
As Tim Lydon warned in The Atlantic last April, “cooperation with Russian scientists has ground to a halt.” Things haven’t improved over the past year. In February, French scientist Jérôme Chappellaz told the Arctic Institute that Russia’s absence from the international scientific community has led to an “environmental emergency.” Field sites have been cut off, data can’t be shared among climate experts based elsewhere, and scientific endeavors have been significantly scaled down.
Russian isolation is being felt everywhere in the Arctic. With global shipping, climate science, international cooperation, and adversarial militaries involved, the rest of the world might also feel the repercussions if something doesn’t change soon.

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.”
