The World's Largest Cross-Country Skirace is Cancelled...Forever

The skirace started in 1922 and the arranger say that they are pleased that they have been able to keep the tradition alive for more than a century. More than 600,000 people have during the years been skiing from Sälen to Mora, the same route that the Swedish king-to-be, Gustav Vasa made in 1521 on his way escaping from Danish soldiers to Norway (although he went the other way, from Mora to Sälen).
Argument: According to Swedish meteorologist Pär Holmgren, the global warming will increase the temperature so it will be impossible to continue with Vasaloppet. The race was cancelled in 1990, and in 2005 the cost for providing the track with enough snow was US$ 1.6 million, or a loss of about US$ 40 per participant. It will not be possible to maintain the contest as it is today, so if there are no revolutionary inventions to provide that much snow, they will either have to quit, or move to a more northern location.
Questions: Apart from the general problem with global warming, will it affect any other similar events? When a city is chosen to host the Winter Olympics, will the availability of snow be an issue that narrows down the candidates? Will the demand for snow increase in the next 20 years due to all established events that will be affected?
