Future of Winter Olympics and snow sports on thin ice, climate change report warns

Climate change is threatening the future of the Winter Olympics and snow sports by eroding the season and forcing more dangerous, artificial conditions, experts have warned in a report published a week before the 2022 Games.
The Beijing Olympics, which start on 4 February, will be the first Winter Games to use almost 100% artificial snow, relying on more than 100 snow generators and 300 snow-cannons working flat-out to cover the ski slopes.

“This is not only energy and water intensive, frequently using chemicals to slow melt, but also delivers a surface that many competitors say is unpredictable and potentially dangerous,” said the Slippery Slopes report, produced by researchers at Loughborough University and the Protect Our Winters environment group.

New climate findings ‘a stark reminder’
‘This is dangerous’


Scottish freestyle skier Laura Donaldson warned that if “freestyle super pipes are formed from snow-making machines in a poor [natural snow] season, the walls of the pipe are solid, vertical ice and the pipe floor is solid ice”.

“This is dangerous for athletes,” she added.

The fears about conditions echo those expressed during last summer’s Tokyo Olympics, when athletes fainted and collapsed due to heat in a city that is on average 2.86C hotter than in 1900.

‘Unfortunate truth’
“The risk is clear: manmade warming is threatening the long-term future of winter sports,” the report warned, citing further studies. It added that global heating is also “reducing the number of climatically suitable host venues for the Winter Olympiad”.
It said the snowy slopes outside Beijing mask “an unfortunate truth: they will be the result of an estimated 49 million gallons of chemically-treated water frozen through snow machines”.
The Beijing organising committee has issued a sustainability report saying the Games’ “smart snowmaking system” could use 20% less water than traditional methods.

Earlier this week Beijing said Chinese authorities would tackle polluters to ensure the Games would be held in a “good environment”, as particularly heavy smog clogged up the capital.
Of the 21 venues used for the Winter Games since the French resort of Chamonix hosted the first in 1924, researchers estimate that, by 2050, only 10 will have the “climate suitability” and natural snowfall levels to host an event.
Chamonix is now rated “high risk” along with venues in Norway, France and Austria, while Vancouver in Canada, Sochi in Russia and Squaw Valley in the United States are deemed “unreliable”.
