The photo is of the Palisades Tahoe ski resort in California—the site of the 1960 Winter Olympics before the name was changed from Squaw Valley Alpine Meadows. The Olympics are unlikely to be held there again: According to a 2014 study, led by Daniel Scott of the University of Waterloo, conditions there will soon be “marginal high risk” and more likely to be “non-reliable.”
It’s actually hard to figure out where to hold the Olympics. As Katherine Martinko, Treehugger senior editor, reported in her post about the Beijing Winter Olympics, they are being held entirely on artificial snow, requiring an estimated 49 million gallons of chemically treated water.
Martinko concluded:
So where could the Olympics go that actually makes sense in the 21st century? A new report, Slippery Slopes, uses Scott’s 2014 data and concludes that toward the end of the century, under a high-emissions scenario—not a bad bet considering the way things are going—there will only be six sites with reliable conditions. The authors conclude:
More recently, a new study led by Scott is even more depressing. It looked at various emission pathways in the Intergovernmental Panel on Climate Change (IPCC) reports and concludes that if nations all meet the targets agreed to in the Paris Agreement, there may still be some choice. But under a high-emissions scenario, we are down to one: Sapporo, Japan.
The recent study interviewed athletes, who risk serious injury in the Winter Olympics “as they race 160 km per hour down a steep slope, throw tomahawks in a superpipe or complete complex aerials 20 metres in the air.” The athletes worry about thin snow, fog, narrow coverage, and rain. Athletes noted warm temperatures make the course “super slushy, the speed slows down, and you get a bunch on bomb holes in the landings which are unsafe!”
The ideal temperature is between 10 degrees Celsius below zero (14 degrees Fahrenheit) and 1 degree Celsius below zero (30 degrees Fahrenheit). Scott and his team conclude in the second study:
But there is another problem with the Olympics ending up in a place like Sapporo, Japan. Unlike ski jumper Felix Gottwald, almost everyone else flies in commercial airliners. One of the serious changes in the world required for a low-emission scenario is to stop doing that. In a study of the 2010 Vancouver Olympics, fully 87% of the 277,677 tonnes of carbon dioxide produced came from delivering the athletes, media, and tourists to the site. Given that Canada and the U.S. are two of the biggest teams, it is likely that the Olympics in Sapporo would generate much higher emissions.
Scott and his team note that we need rapid decarbonization of the global economy. Flying in half a million people from all over the world is not exactly consistent with that. The very act of attending the Winter Olympics is contributing to their demise. Perhaps it is time to consider whether we should be doing this at all.
