Top Alpine skiers say shrinking glaciers are threatening the future of their sport and the wider planet.
Lindsey Vonn, Mikaela Shiffrin and Federica Brignone highlighted the issue during the Winter Games in Cortina.
Glaciers once visible from the host town have largely disappeared.
Major ice fields now lie far away, including the rapidly melting Marmolada.
Scientists say Italy has lost more than 200 square kilometres of glacier area since the late 1950s.
Athletes train on glaciers for reliable snow, making the changes impossible for them to ignore.
Vonn said many slopes she used as a child have already vanished.
Shiffrin called the crisis central to the future of skiing.
Research shows glacier loss has accelerated in the past two decades.
Smaller glaciers near Cortina have shrunk by about one-third since the early 1960s.
Some are now too small to qualify for global monitoring projects.
The melting ice also increases natural hazards and threatens water supplies.
A collapse on the Marmolada in 2022 killed 11 hikers.
If global warming reaches 2.7°C, the glacier could largely disappear by 2034.
Limiting warming to 1.5°C could preserve around 100 Alpine glaciers.
Scientists say decisions taken this decade will determine how much ice survives.
Skiers across nations report less snow, exposed rock and growing crevasses on training routes.
Many are now calling for stronger climate action and an end to fossil-fuel sponsorship in winter sports.
