Vanishing Ice

Outfitted for a day of ice climbing, students test

their skills on a glacier named the Mer de Glace,

or Sea of Ice—one of the largest glaciers in the

Alps. It extends eight miles (12 kilometers) on the

northern side of Mont Blanc near Chamonix,

France. Like other glaciers throughout the Alps,

this one is receding. If current trends hold,

scientists predict that 50 to 80 percent of

remaining Alpine glaciers could vanish by 2100.
