I originally posted this in 2014. But, with Killington recently hosting a World Cup race in November, and given how much they relied on artificial snow, it seemed appropriate to bubble it back up. Snowmaking can be an extremely energy-intensive activity. With fewer solidly snowy winters, can skiing be sustainable [PDF]?
The 2014 Winter Olympics being held in Sochi, Russia are located at one of the warmest locations in the history of the games. Setting aside for now the slow creep of a warming climate, Sochi, located at the eastern shores of the Black Sea, is a humid subtropical climate with an average winter temperature of around 50F during the day and still above freezing at night. In the higher elevations in the nearby Caucasus Mountains, where the events are taking place, daytime temperatures still average above freezing during the day. So, while it is a far better location for the actual “winter” portion of the games than the palm-tree-lined streets of the city of Sochi proper, it still is not the ideal location to host the Winter Games.
