Temperatures have increased twice as much as the global temperature since the 19th century. Each year, 3 % of glacial ice is lost, and if this continues, there won’t be any more glaciers left on the Alps by 2050 (in 2006 it was estimated to last until 2100). Not only will the loss of the Alps hurt the European ski industry, but it will also change the supply of drinking and irrigation water and lead to more falling rocks.
