The South Asian Brown Clouds are
gigantic clouds of dust, smoke,
soot, and other pollutants that
stretch over much of South Asia.
One is visible here over eastern
China.

Acid rain can eat through stone and metal. It has accelerated
the natural weathering process of this scarred stone angel's face.

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.
