To try to prevent financial meltdown resorts are increasingly having to rely on making their own snow.
In Switzerland, for example, prior to 1990 the making of artificial snow was unheard of.
As millions of us prepare to jet off to the slopes, many resorts are finally taking responsibility for the fragile ecosystems they depend on.
But, as Simon Birch reports, it may be too little too late With the Turin Winter Olympics kicking off on Friday, the world's media will be focussing on the events and drama unfolding on the icy slopes of the Italian Alps.
Run jointly by the National Ski Areas Association and the Natural Resources Defense Council, Keep Winter Cool is supported by more than 300 ski resorts across the US.
"Global warming is a key environmental issue and a bottom line issue for the $3bn ski industry and its employees," says NSAA president Michael Berry.
In the face of this avalanche of dire warnings, the good news is that despite the fact that climate change has more to do with humanity's global activities than the impact of skiers and boarders whizzing down the slopes, an increasing number of ski resorts, tour operators and other members of the winter sports industry are looking at ways to minimise the impact of skiing on the mountain environment.
