Let’s learn about the science of the Winter Olympics

From scientific innovations to climate change, there’s plenty of science among the sport

Snowboarders, skiers and other athletes are gearing up to compete in the 2022 Winter Olympics in Beijing, China. Scientific advances may give some competitors an edge, but climate change threatens the very future of these games.

In just a few days, athletes from around the world will compete in the Winter Olympics in Beijing, China. The Olympic games are a spectacle of speed and grace. Curlers deftly nudge stones into place. Figure skaters whip themselves into fancy twirls on the balance of a blade. Snowboarders ride rails and launch off of ramps into daring flips and twists. Every Olympian has trained for years to show off their skills on the world stage.

In contests between such elite athletes, tiny details can make the difference between silver and gold. The chemistry of ski wax, for instance, affects how well skis glide across or grip snow. The recipe can make or break a skier’s performance. In bobsledding, meanwhile, shoe stiffness is key. Just the right amount of bendiness can give athletes the boost of speed they need to take first place.

But there’s one key piece of Winter Olympic equipment no one can totally control: cold weather. Without it, athletes like skiers and snowboarders can’t compete. Unfortunately, many cities may soon be too warm to host the Winter Olympics. The reason: human-caused climate change. If it doesn’t get cold enough, snow can’t fall. In fact, this is the first Winter Olympics ever that will completely depend on artificial, rather than natural, snow. That could become the norm in the future.

Some technology does exist to coax clouds into making more snow. This weather-control technology helped create clear skies at the Beijing Summer Olympics in 2008. But tampering with the weather may have unintended consequences. And it still won’t produce enough snow to keep the slopes covered.

Climate change threatens future Winter Olympics Higher temperatures and less snow may make many former Winter Olympics sites unfit to host future games. (2/9/2018) Readability: 8.3
