Beijing’s bid for the 2022 Winter Olympics relied solely on covering their cold-but-dry mountain venues, Yangqing and Zhangjiakou, with 100% artificial snow.

For every cubic meter of snow produced, half a cubic meter of water was required, raising concerns about Beijing’s bid.
Clean water is a scarcity in the northern region around Beijing and within the city itself. The region pumps in 70% of its water from southern China.
In their bid, Beijing estimated 49 million gallons of water would be needed to maintain the slopes, but, in reality, 343 million gallons were turned into snow.
Snow machines mix and cool compressed air and water, releasing tiny balls of ice onto the slopes and compacting four times denser than natural snow.
The presence of artificial snow has increased in the Winter Olympics. Artificial snow made up 80% of Sochi’s snow, 90% of Pyeongchang’s snow, and 100% of Beijing’s snow.

In 1980, Lake Placid was the first Olympic venue to use artificial snow, but troubles with lack of snowfall are a recurring theme. In 1964, Austrian soldiers hauled 20,000 blocks of ice to prevent cancellation of the winter games. Vancouver, in addition to snow machines, transported snow with semi-trucks from higher to lower elevations of Cypress mountain.

Skiers expressed concerns over artificial snow courses. The snow’s closer packing allows faster ski times but increases the likelihood of collisions. Athletes crash on snow that “feels like concrete”. In turn, the density allows for easy construction of ski and snowboard ramps.
A study found that, with global temperatures rising, only one of the past 21 Winter Olympic venues, would be able to provide natural snow by the 2080 games.
To keep the global athletic competition alive, fake snow will be the way to go.

I found this topic really interesting! I didn’t know fake snow was used in high quantities for the Olympics… let alone 100% of the snow for the recent Beijing Winter Olympics. I can tell that the audience is piece is pretty general as very minimal amounts if jargon was used. I believe this is written in a journalistic style as the paragraphs are quite short and follows the inverted pyramid structure.
Solid post! I had no idea fake snow is produced in su h large quantities and requires that much water. That’s pretty crazy Beijing Winter Olympics used 100% fake snow.
I wonder if there’s a chemical alternative that’s cheaper than water and readily available that could be a substitute. (maybe something that doesn’t even melt!)
Nice graphic, everything was clear and easy to interpret, same for the journalistic style.
