Belgian biathlete Maya Cloetens can’t help but think about the future of winter sports as she trains for next month’s Olympic Games in Milan and Cortina, Italy.

Evidence of climate change is all around her in the mountains above Grenoble, France, where the 24-year-old fell in love with the sport that combines cross-country skiing and shooting.

Grenoble hosted the 1968 Winter Olympics, but its winters are shorter and milder nowadays, and with less consistent heavy snowfall. When the games return to the French Alps in 2030, Grenoble won’t be the focal point.
