The Impact of Alpine Tourism on Glacial Landscape Degradation

Quick fact

Soot from ski resorts and hiking traffic can darken glacier surfaces, reducing their reflectivity (albedo) by up to 10%, which can increase melt rates by as much as 30% in heavily visited areas.

Why this is interesting

You’re standing on a glacier that has been here for thousands of years, but your footprints might be changing it more than you think. How can a holiday activity permanently scar a landscape that has endured ice ages?
