As glaciers melt and permafrost thaws, Longyearbyen, on the remote Arctic islands of Svalbard, faces climate-induced problems from tap water to housebuilding to landslides

• Heavy metals make Norwegian village’s tap water toxic

On a rugged mountain plateau of snow-dusted rocks, in the remote archipelago of Svalbard, a glaciologist, Andy Hodson, points out the “ears” of ice, white against the rock, that gave Foxfonna glacier its name, after the arctic fox.

The small glacier, on a mountain 8 miles (15km) outside the Norwegian village of Longyearbyen, is a popular summer hike for tourists who come here seeking the Arctic experience.

Peak of French mountain now 4,807 metres high and fluctuates year by year due to changes in Alpine climate

Western Europe’s highest mountain shrank by more than a metre last year. The peak of Mont Blanc in France now stands 4,807.47 metres above sea level, a team of surveyors said on Wednesday, putting “the roof of Europe” 1.29 metres lower than in 2025.

The mountain is about 4,792 metres tall but the summit constantly shifts as heat, wind and precipitation change the thickness of snow and ice on top. The height scientists recorded during an expedition last month was 1.88 metres greater than it was in 2023, when it reached the lowest levels in recent memory.
