Who lives there
Millions of people across eight countries, most of them in the Russian Arctic and northern Scandinavia, the rest scattered across Alaska, Canada, Greenland and Iceland. Indigenous peoples throughout: Inuit across Greenland, Canada, Alaska and Chukotka; Sámi across northern Norway, Sweden, Finland and the Kola Peninsula; Nenets, Evenki, Chukchi, Yupik and many others across Siberia; Gwich'in and other Athabaskan peoples inland in Alaska and Yukon.
Cities. Murmansk, the largest, ice-free thanks to the tail of the Gulf Stream. Tromsø and Norilsk, Nuuk and Iqaluit, Utqiaġvik on Alaska's north coast, Longyearbyen on Svalbard. Then hundreds of villages of a few hundred people, reached by air, sea or winter road, with a school, a store, a clinic, and a runway.
The coast in retreat
Sea ice used to arrive in autumn and lock the shore before the storm season. Now storms come first and find open water and thawing bluffs. Villages built on barrier islands and spits along the Alaskan coast are the sharpest cases. Shishmaref and Kivalina have voted on relocation and wait on funding and a site. Newtok, on the Bering Sea side, has begun moving residents across the river to Mertarvik, a rare example of a full village relocation actually underway.
The costs are not only in buildings. Cemeteries erode. Ice cellars that kept whale and walrus meat frozen through the summer fill with water as the ground warms. Sea ice that served as a highway between settlements and to hunting grounds is thinner and less predictable, and travel over it more dangerous. Rivers used as winter roads freeze late and break up early.
Food and animals
Subsistence still matters. Bowhead whale in Alaskan coastal communities under a quota system. Seal, walrus, fish, caribou, berries, birds' eggs. Reindeer herding across Sápmi and Siberia. Each depends on conditions that are shifting.
Rain-on-snow. Warm spells in winter bring rain that freezes into a crust over the lichen, and reindeer and caribou cannot dig through it. Whole herds starve in bad years. Caribou migration timing drifts out of step with plant growth. Shrubs replace lichen on the tundra.
Polar bears hunt seals from sea ice. Less ice, less hunting, longer fasts on land, more bears near villages looking for food. Walrus that would rest on ice between dives now haul out on beaches in huge crowds, and stampedes kill the young. Fish move north as the water warms: Atlantic species into the Barents Sea, Pacific species through the Bering Strait, upending who catches what.
Fire. Boreal forest and tundra burn more, and the smoke reaches communities that never had a fire season. Burned ground thaws faster, as the permafrost note sets out.
Who decides
Arctic Council. The eight Arctic states: Canada, the Kingdom of Denmark, Finland, Iceland, Norway, Russia, Sweden and the United States. Six Indigenous organisations sit as Permanent Participants, among them the Inuit Circumpolar Council, the Saami Council and the Gwich'in Council International. Working groups on the marine environment, pollutants, flora and fauna, emergency response. Consensus, no binding powers, a chair rotating between states. Military security is outside its remit by design.
Law of the sea. The United Nations Convention on the Law of the Sea governs zones, shelves and navigation, and its Article 234 gives coastal states extra room to regulate ice-covered waters. Details in the shipping note. A separate agreement among the coastal states and major fishing nations bars commercial fishing in the high seas of the central Arctic Ocean while science catches up.
Svalbard Treaty. Gives Norway sovereignty over the archipelago while allowing nationals of the signatory states equal access to economic activity there. The reason Longyearbyen has residents of many nationalities and a Russian mining settlement at Barentsburg.
Self-government. Greenland governs its own domestic affairs within the Kingdom of Denmark, including its minerals. Nunavut in Canada was created out of a land claims agreement with the Inuit. Sámi parliaments in Norway, Sweden and Finland advise on matters affecting Sámi, with limited powers. Alaska Native corporations own land and run businesses under a settlement act. Each arrangement shapes who has standing when the ground shifts.
| Body | Type | Scope | Binding force |
|---|---|---|---|
| Arctic Council | Intergovernmental forum | Environment, sustainable development | Consensus recommendations; a few agreements negotiated under its auspices |
| Law of the Sea Convention | Global treaty | Maritime zones, navigation, seabed | Binding on parties |
| Svalbard Treaty | Regional treaty | Sovereignty and access on Svalbard | Binding on parties |
| National and regional governments | Domestic law | Land, permits, relocation funding | Binding within territory |
What changes for towns
Longer open-water seasons mean longer resupply windows and more cruise ships, welcome in some harbours and resented in others. Warmer winters mean rain, ice on roads, slush where there was snow, and avalanche and landslide risk on slopes above settlements such as Longyearbyen. Mines and gas fields bring wages and roads and also trucks, dust, and outside workers. Tourism sells the very thing that is disappearing.
The recurring question is who pays when the ground fails: the household, the municipality, the state, the companies whose emissions warmed it. The recurring answer so far is nobody in particular, and slowly.
