The Arctic as Geopolitical Frontier

The Thawing Frontier

For most of modern history, the Arctic was too frozen, too remote, and too harsh to matter much in geopolitics. That era is ending. The Arctic is warming at roughly four times the global average, and summer sea ice extent has declined by over 40% since satellite records began in 1979. What was once an impenetrable ice sheet is becoming a navigable ocean — and with navigation comes competition.

The stakes are enormous. The US Geological Survey estimates that the Arctic holds roughly 13% of the world's undiscovered oil reserves, 30% of its undiscovered natural gas, and significant deposits of rare earth minerals. New shipping routes through Arctic waters could cut transit times between Europe and Asia by up to 40%. And the region's strategic geography — sitting atop North America, Europe, and Russia, with the shortest ballistic-missile trajectories between the United States and Russia arcing over the pole — makes it a potential theater for military competition between great powers.

Who Owns the Arctic?

The short answer is: it depends on where you draw the lines. Under the UN Convention on the Law of the Sea (UNCLOS, adopted 1982, in force 1994), coastal states control a 200-nautical-mile Exclusive Economic Zone (EEZ). But states can claim sovereign rights over the continental shelf beyond the EEZ if they prove the seabed is a natural geological extension of their landmass. Russia, Canada, Denmark, and Norway have all filed submissions with the UN Commission on the Limits of the Continental Shelf (CLCS), and several of these claims overlap.

Russia's claim is the most ambitious. In 2007, a Russian submersible planted a titanium flag on the seabed beneath the North Pole — a symbolic gesture that rattled other Arctic states. Russia argues that the Lomonosov Ridge, an underwater mountain range, connects to the Siberian continental shelf, giving it rights to roughly half the Arctic Ocean floor. Denmark, via Greenland, argues the same ridge extends from its territory — so the claims directly collide.

The United States has not ratified UNCLOS, which limits its ability to file formal continental-shelf claims — a fact that frustrates US Arctic strategists and military planners who see ratification as essential to securing American interests in the region.

Why It Matters Now

Three forces are converging. First, climate change is making the Arctic physically accessible in ways never before possible. Second, global demand for energy, minerals, and shorter trade routes gives states powerful economic incentives to stake claims. Third, the deterioration of relations between Russia and the West since 2014 has transformed the Arctic from a zone of scientific cooperation into a potential theater of strategic rivalry.

The Arctic Council, created in 1996 as a forum for peaceful cooperation, paused most activities with Russia after the 2022 invasion of Ukraine. The institution that was supposed to manage Arctic governance is now partly frozen — ironically, even as the ice that defined the region is not.

The eight Arctic states approach the region with distinct priorities:

Note that three of the five Arctic coastal states are NATO members, and with Finland and Sweden's accession, seven of the eight Arctic Council states now belong to the alliance — leaving Russia diplomatically isolated in the forum it helped build.
