Will Sochi have enough snow? | Grist

Will Sochi have enough snow? | Grist: Low snowfall has become a chronic problem for skiers and snowboarders worldwide, which has turned many of them into vocal activists against climate change. President Obama even mentioned snow sports in his major global warming speech last summer, when he said that “mountain communities worry about what smaller snowpacks will mean for tourism.”



In some cases, global warming can lead to increased heavy precipitation of all kinds, and that includes snow, as anyone who lived through the recent polar vortex in the eastern U.S. can attest. But the best conditions for snow sports depend on a snow cover that lasts through the winter, not simply a couple serious blizzards. Over the course of the season, high temperatures can burn through even the heaviest snowfall, and according to Porter Fox, that’s already happening from the Rockies to Sochi.
