Guinness record – the world's largest postcard against climate change

A powerful statement against climate change: 125,000 postcards with messages from young people worldwide come together on world’s biggest postcard.

At over 3,400m altitude, the Aletsch glacier was chosen as the location for the Guinness world record because it is a powerful image of the strong impact of climate change on high mountain regions. Many of the world’s glaciers are shrinking rapidly and will disappear completely in the near future. Disappearing glaciers are a sight that can be observed all over the world and Switzerland, with its many glaciers, is particularly affected.
