Ananova:

Swiss authorities are planning to wrap mountain glaciers with tin foil this summer in an effort to stop them melting.

Carlo Danioth, head of mountain rescue services in Andermatt, said: "We will initially cover around 30,000 square feet on the upper Gurschen glacier at the beginning of May as a test."

Scientists hope that the high-tech foil will prevent the sun's rays from melting the ice in popular ski resorts during the summer months.

Glacier expert Martin Funk said: "The foil reflects almost all the sun's rays. That will sharply reduce the rate of melting."

And other resorts like Saas-Fee and Titlis and some Austrian glaciers have said that they plan to test similar schemes this summer.

Environmental groups have criticised the £45,000 plan at Andermatt as "absurd".

Raimund Rosewald, head of a landscape protection foundation, said: "We cannot stop the glaciers melting using foil."
