Iceland’s Glaciers Are Shrinking. Iceland is losing its glaciers. Since 1900, the country has warmed by about 1.5 °C. This warming makes snow melt faster. Glaciers cannot keep up. By the late 19th century, glaciers covered their largest area. They have shrunk by about 19 % in area since then Between 2000 and 2017, they lost around 700 km²—about 43 km² per year. That is roughly 7 % of their ice volume.

Why Are They Melting So Fast?
- Rising Temperatures.
Iceland’s average temperature has gone up about 0.47 °C every decade in the last 30 years. - Less Snow, More Rain.
Warmer winters mean less snowfall. Summer melts more ice. - Volcanic Ash.
Active volcanoes drop ash on ice. This makes glaciers darker. Dark ice melts faster. - Calving into Water.
Glaciers like Breiðamerkurjökull break off into lakes or the sea. This makes them shrink faster, about one-third of the mass loss.
Risks and New Hazards
Rising Sea Levels
All Iceland’s glaciers hold about 3,500 km³ of ice, including 3,000 km³ in Vatnajökull alone. If they all melted, global sea levels would rise by about 1 cm.
Rock and Land Instability
Glacier retreat makes nearby land unstable. This can lead to rockfalls, avalanches, and floods.
Changing Rivers and Lakes
Meltwater creates new lakes and shifts river paths. Trails and bridges may disappear or become dangerous.
Tourism Risks
Glaciers are key attractions in Iceland. They boost local jobs and income. In 2019, tourism made up about 33 % of Iceland’s GDP. Most tourists (97 %) visit for nature, including glaciers.
Last-Chance Tourism
Many people hurry to see melting glaciers now, in case they vanish later. This “last-chance tourism” brings more visitors now.
Safety Hazards
Melting ice and unstable terrain make tours riskier. An ice cave collapse in 2024 killed one tourist and injured another. Parks now inspect caves weekly .
Tour Changes
Tour groups must adapt. On Solheimajökull, guides now drop tourists by boat into the lagoon. They avoid long, dangerous hikes.
Visitor Demand Studies
Research in Vatnajökull National Park asked 565 tourists about glacier tourism.
Results show:
- Some will still go even as glaciers shrink.
- Others may stop if safety, beauty, or access decline.
- Tourists differ in what affects their visit.
Tour guides and park managers must tailor trips. They need to match safety, education, and experience goals to different visitor types .
Economic Stakes
Tourism is Iceland’s top export. In 2017, tourism brought 42 % of export income. Seafood was just 17 % .
About 26,800 people worked directly in tourism out of 187,000 total in 2017.
If glacier tourism drops, jobs could suffer. Glacier-related tours include ice walks, visits to ice caves, boat trips, and lagoon sightseeing. Many towns rely on glacier tourists.
What Can Be Done?
Better Safety Rules
Parks now require weekly cave checks. They license only safe tour operators .
Smarter Tours
Guides use boats to reach glaciers. This cuts risks and travel time.
Tourist Education
Guides and parks should explain risks and climate change. They can prepare visitors for unstable terrain.
Diversify Attractions
Tourism should not rely only on glaciers. Iceland has volcanoes, hot springs, forests, and culture to offer.
Climate Action
To save remaining ice, countries must limit warming. A global study shows nearly 40 % of glaciers worldwide are doomed if warming continues. Keeping warming below 1.5 °C can save half of that ice .
A Deep Study: Communication & Risk
The case of the Svínafellsheiði fracture shows how to manage risk.
The tool? Participatory risk communication.
It means local people, guides, scientists, and managers talk and plan together. This improves safety. Tourists then trust the info. Tour guides know what is safe or dangerous. They can properly alert visitors .
Foreign staff especially need clear guidance. Most tourism workers speak English, not always Icelandic .
Conclusion
- Iceland’s glaciers are melting fast.
- This affects nature, safety, and tourism.
- Glacier tourism supports many jobs.
- But shrinkage brings new risks and fewer visitors.
- Smart planning and tools can help.
- Still, global action on climate change is most vital.
Iceland must balance caring for glaciers with welcoming tourists.
It needs safety, diverse travel options, and climate solutions—so future generations can still marvel at ice, not just remember it.
