Climate change is threatening the town of Aspen, Colorado, who's ski season is a month shorter than it was 50 years ago. It will be an estimated two weeks short by 2030 and will continue to shrink. But Aspen isn't the only struggling operation in the world. Here are how five other ski resorts are fighting the loss of snow.
In 70 years, holding the Winter Games in Sochi would be entirely impossible, according to a recent study looking at climate change's impact on the current and former Olympic sites. Even now, Sochi, which is technically a subtropical region, has struggled with keeping enough snowpack for the Games.
What they've done: Sochi is a small winter resort that had to scale-up big this year – costing an estimated $51 billion, thanks in large part to the biggest artificial snow-making system in the world. To get snow to the slopes, Russians have had to move water up the mountain with some 400 generators, tapping into two new reservoirs, a move that environmentalists argue may cause ecological damage to the regions for decades to come.
