In a post-truth world, the fight against climate change is still winnable

Jan 6, 2017

The Aletsch Glacier is pictured from the Eggishorn summit in Fiesch, Switzerland, August 22, 2015. One of Europe's biggest glaciers, the Great Aletsch coils 23 km (14 miles) through the Swiss Alps - and yet this mighty river of ice could almost vanish in the lifetimes of people born today because of climate change. The glacier, 900 metres (2,950 feet) thick at one point, has retreated about 3 km (1.9 miles) since 1870 and that pace is quickening.
