Cloak protects glacier from sun

BBC News: "Workers at a Swiss ski resort have wrapped part of a retreating glacier in reflective sheeting to protect it, they say, from global warming. The Gurschen glacier, nearly 3,000m (10,000ft) above sea level, is melting like many others worldwide, with the worst damage done in summer. The thin protective layer of foil covers an area of 3-4,000 sq m (about 43,000 sq ft)."
