Olympic skiers Vonn, Shiffrin and Brignone voice concern over melting glaciers
Several Olympic skiers including Lindsey Vonn, Mikaela Shiffrin and Federica Brignone said nearby glaciers have dramatically shrunk; Italian researchers report more than 200 square kilometres of glacier loss since the late 1950s and projects indicate some glaciers could largely disappear within years under high-warming scenarios.
