Climate change is happening and the Alps are particularly sensitive to the changes. In the Jungfrau area the first signs are getting visible. On seven different trails in Grindelwald, Wengen and Mürren you learn interesting facts about the climate change with the multimedia guide on iPhones.
The climate change will be particularly challenging for the tourism. This trail with five stations shows also new opportunities for the region. E.g. hot summers will bring more people to the mountains to enjoy the fresh air. The wormer climate will instead create additional problems for the mountain railways. They may have to rehabilitate the buildings, because the permafrost is melting slowly, as for example on the Schilthorn.
