But at lower elevations, where cross-country and other events are held, athletes and organizers have been contending with rain; thin, sometimes slushy snow; and icy, machine-made surfaces.

“Most of our races are on machine-made snow,” 2026 U.S. Olympic team cross-country skier Rosie Brennan told us ahead of the Games. “TV production is great at making it look like we are in wintry, snowy places, but this year has been particularly bad.”

As scientists who study mountain snow, water resources and the human impact of warming winters, we see winter’s changes through data: rising temperatures, shrinking snowpack, shorter snow seasons. ......................(more)
