CORTINA D'AMPEZZO, Italy - The Milan Cortina Winter Paralympic Games are taking place amid concerns over the amount and quality of snow at venues, as global warming raises questions about holding the sporting event in March in many parts of the world.

Backdropped by the Dolomites of northern Italy, the games are being held on partly artificial snow amid unseasonably warm conditions, which some athletes say are creating slushy surfaces that are hard to compete on, with even seasoned skiers falling during events.
