Spencer Tunick is a New York artist famous for staging photographs of large nude gatherings in public places. His latest work of art, sponsored by Greenpeace, took place on Aletsch glacier in Switzerland last Saturday. About 600 nude volunteers formed a “living sculpture” in an effort to promote awareness of climate change. Most of Swizerland’s glaciers are expected to disappear by 2080 as a result of global warming. The temperature during Tunick’s photoshoot hovered around 50 ° F (10 ° C) – there must have been lots of shrinkage (and erect nipples).
