>> Switzerland's Chocolate Box Mountains are losing their snow at an alarming rate. A Swiss study of satellite images over 22 years has found areas of permanent snow have shrunk by about 5%. That's a loss of about 2,000 square kilometers, probably because of global warming. The red areas on this map show snowless areas growing, at the expense of the blue areas of permanent or plentiful snow.
>> Areas with almost no snow have seen an 8% increase of their surface area. Which is a very significant increase, representing a bit more then 5,000 square kilometers of Swiss territory. What we have shown is the evolution of the snow cover in Switzerland over the last two decades.
And what we have observed is that the snow is gradually disappearing.>> Switzerland's majestic glaciers are also melting. This photos show how far the Rhone Glacier has receded over 11 years. The Swiss scientists behind the study are now teaming up with climate change experts to confirm whether global warming has, as they expect, caused the changes.
Climate change is a growing fear for Switzerland's winter sports industry. Warmer, shorter winters have already forced many European ski resorts to rely on artificial snow.
