Giant postcard captured in Switzerland, wishing to fight climate change

A photo taken on Nov. 16, 2018 by a drone shows an approximately 27,000-square-foot giant postcard made from contributions of over 125,000 individual postcards containing messages aiming to fight climate change and global warming in Switzerland. Each individual postcard includes climate change promises and messages from children and youth from 35 countries and regions worldwide and aims to establish the Guinness world record of the largest composed postcard with the most overall contributors. The 1.5 degrees Celsius written in the center of the postcard refers to the target for limiting global warming. [Photo: IC/Valentin Flauraud]
