Longyearbyen Airport Faces Arctic Aviation Emergency as Permafrost Thaws
Longyearbyen Airport, also known as Svalbard Airport (LYR), is now at the center of a growing crisis in the Arctic. As of June 2025, the airport’s single runway is “disintegrating” because the permafrost beneath it is melting faster than ever before. This situation is now being called an “Arctic aviation emergency” by experts, and it threatens the only year-round air link for Svalbard—a remote Norwegian archipelago deep in the Arctic Circle.
What’s Happening at Longyearbyen Airport?
The main problem is the permafrost, which is a layer of frozen ground that has stayed solid for thousands of years. The airport’s runway was built on this permafrost in the 1970s, when it was thought to be stable and strong enough to hold heavy planes. But now, because of the climate crisis, the permafrost is thawing. This causes the ground to sink and crack, making the runway unstable and dangerous for planes to land and take off.
As of June 2025:
– Longyearbyen Airport remains open but is under strict watch. Every day, airport staff check the runway for cracks and sinking ground, especially during the warmer summer months.
– Two airlines—SAS and Norwegian Air Shuttle—still operate flights to Tromsø and Oslo. There are no flights within Svalbard itself; all scheduled flights go to mainland Norway.
– Norwegian authorities have increased monitoring and repairs to keep the airport running, but the situation is getting worse as the climate warms.
Why Is This an Emergency?
The airport is Svalbard’s only year-round air connection to the outside world. If Longyearbyen Airport becomes unusable, the community would have to rely on ships for supplies and travel. But ships can take up to two days each way, and sea routes are not always open, especially in winter. This would make it much harder to get food, medicine, and other essentials to the people living in Svalbard.
Key Facts and Figures
- Runway: 2,300 meters long, built on permafrost in the 1970s.
- Passenger Volume: Over 180,000 passengers in 2019, with numbers rising again in 2025 due to a boom in Arctic tourism.
- Temperature Rise: Svalbard’s average temperature has gone up by about 7.2°F (4°C) over the last 100 years. The Arctic is warming up to four times faster than the rest of the world.
- Flight Operations: SAS and Norwegian Air Shuttle fly to Tromsø and Oslo, with SAS handling about two-thirds of all departures.
Voices from the Frontline
Ragnhild Kommisrud, the airport manager, explained, “During the summer months, we check the runway meticulously every day, as the soil must subside. This is a challenge that we only expect to get worse with time. The melting of permafrost in Svalbard is not caused by local emissions or activity alone but is a direct result of global climate change.”
Jon-Ivar Nygård, Norway’s Minister of Transport, said, “The government’s goal in the National Aviation Strategy and the National Transport Plan 2025–2036 is to accelerate the transition to zero- and low-emission aviation. One billion kroner has been allocated for this purpose.”
How Is the Crisis Being Managed?
Airport staff and Norwegian authorities are working hard to keep Longyearbyen Airport open and safe. Here’s what they are doing:
- Daily Inspections: Every day, especially in summer, staff check the runway for cracks, sinking, and other signs of damage.
- Constant Repairs: Maintenance crews patch and reinforce the runway as soon as problems appear.
- Flight Restrictions: If the runway becomes too unstable, there may be limits on the size and number of planes allowed to land.
- Engineering Solutions: Authorities are looking at ways to insulate the runway or even move key infrastructure, but these fixes are expensive and difficult to carry out in the Arctic.
- Transition to Low-Emission Aviation: Norway is investing in new types of planes that produce less pollution, with test flights planned for late 2025.
What Is Permafrost and Why Does It Matter?
Permafrost is ground that stays frozen for at least two years in a row. In places like Svalbard, it has been frozen for thousands of years. When permafrost thaws, the ground can sink, shift, or even collapse. This is a big problem for buildings, roads, and runways built on top of it.
At Longyearbyen Airport, the thawing permafrost is causing the runway to crack and sink. This makes it unsafe for planes, especially larger ones that need a strong, flat surface to land and take off.
Why Is the Permafrost Thawing So Fast?
The main reason is the climate crisis. Svalbard has warmed by about 4°C (7.2°F) in the last century, which is much faster than most other places on Earth. Scientists say the Arctic is warming up to four times faster than the global average. This rapid warming is melting the permafrost, which used to be a solid foundation for the airport and other buildings.
Who Is Affected by the Crisis?
The problems at Longyearbyen Airport affect many different groups:
- Local Residents: People living in Svalbard depend on the airport for food, medicine, and other supplies. If the airport closes, they would have to wait days for ships to bring what they need.
- Tourists: Svalbard is a popular place for adventure and eco-tourism. If flights are canceled or delayed, it could hurt the local economy and people who work in tourism.
- Scientists: Many researchers travel to Svalbard to study the Arctic. The airport is their main way in and out.
- Emergency Services: The airport is used for medical evacuations and bringing in help during emergencies. If it closes, it could put lives at risk.
What Are the Wider Implications?
The crisis at Longyearbyen Airport is not just a local problem. It shows how climate change is already affecting infrastructure in the Arctic and could soon impact other places built on permafrost. Climate scientists warn that Svalbard is a “canary in the coal mine”—an early warning sign of what could happen elsewhere as the planet warms.
Aviation authorities say that new ways of building and maintaining airports in cold regions are needed. They also stress the importance of working together internationally to find solutions.
Impact on Supply Chains and the Economy
Svalbard’s community and economy rely heavily on air travel. The airport is the main way to bring in:
- Food and Supplies: Most goods arrive by air, especially in winter when sea routes are blocked by ice.
- Medical Evacuations: The airport is used to fly patients to hospitals on the mainland.
- Tourists: The region’s booming adventure tourism industry depends on regular flights.
If the airport becomes unusable, supplies would have to come by ship. This journey can take up to two days each way and is not always possible in bad weather or during the long Arctic winter. This would make life much harder for everyone in Svalbard.
Tourism at Risk
Tourism is a big part of Svalbard’s economy. In 2019, over 180,000 passengers used the airport, and numbers are rising again in 2025. Many visitors come for adventure trips, wildlife watching, and to see the northern lights. If flights are disrupted, it could mean fewer tourists and lost income for local businesses.
Emergency Preparedness
The thawing permafrost not only affects the runway but also increases the risk of avalanches, landslides, and sudden ground collapse. This makes it harder to keep people safe and respond quickly to emergencies.
What Is Being Done to Fix the Problem?
Norwegian authorities are taking several steps to try to keep Longyearbyen Airport open and safe:
- Daily Runway Inspections: Staff check for cracks and sinking every day, especially during the summer thaw.
- Ongoing Repairs: Maintenance crews patch and reinforce the runway as soon as they find problems.
- Flight Restrictions: There may be limits on the size and number of planes allowed to land during periods of severe instability.
- Long-Term Solutions: Authorities are looking at ways to insulate the runway or even move key infrastructure. These fixes are expensive and technically challenging.
- Transition to Low-Emission Aviation: Norway is investing in new types of planes that produce less pollution, with demonstration flights planned for late 2025.
Official Response and Policy Changes
The Norwegian government has made the crisis at Longyearbyen Airport a top priority. In the National Transport Plan 2025–2036, one billion kroner has been set aside to help speed up the move to zero- and low-emission aviation. Avinor, the state-owned airport operator, and the Civil Aviation Authority are working together to make Norway a leader in Arctic aviation adaptation.
Expert Opinions
- Climate Scientists: Warn that thawing permafrost is a threat to all infrastructure in the Arctic, not just airports.
- Aviation Authorities: Stress the need for new building methods and international cooperation.
- Local Community: Worry about the future of their supply chains, economy, and safety.
- Tourism Industry: Fears big losses if flights are disrupted.
Background: How Did We Get Here?
Longyearbyen Airport was built in the 1970s, when permafrost was seen as a solid foundation. At that time, Svalbard’s economy was based on coal mining, but this has declined in recent years. The coal-fired power station was replaced with diesel in 2023, and the region now depends more on tourism and research.
Over the last 20 years, Svalbard has warmed faster than almost anywhere else on Earth. This rapid warming is now threatening all infrastructure built on permafrost, including homes, roads, and the airport.
What’s Next for Longyearbyen Airport?
- Short-Term: Daily monitoring and emergency repairs will continue. There may be flight restrictions during periods of instability.
- Medium-Term: Authorities are looking at engineering solutions to stabilize the runway, but these may only delay the need for major reconstruction or even moving the airport.
- Long-Term: Norway is investing in zero- and low-emission aviation, hoping to lead the way in adapting to Arctic conditions.
- Uncertainty: If the permafrost keeps thawing, the airport’s long-term future is in doubt. This could have serious consequences for Svalbard’s connection to the outside world and its survival as a community.
