Stunning images from high in the Himalayas – showing the extent by which many glaciers have shrunk in the past 80 years or so – have gone on display at the Royal Geographical Society in central London. Between 2007 and 2010, David Breashears retraced the steps of early photographic pioneers such as Major E O Wheeler, George Mallory and Vittorio Sella – to try to re-take their views of breathtaking glacial vistas. The mountaineer and photographer is the founder of GlacierWorks, a non-profit organisation that uses art, science and adventure to raise public awareness about the consequences of climate change in the Himalayas.
