Snow cover and glaciers in most of the Alps have declined dramatically
over the past 20 years, particularly at elevations below 6,500 feet.
The loss is already hurting tourism and eventually may disrupt hydropower—
the predominant source of energy in the Alps.

stitched together and laid

from melting. But they’re
complicated to install and
can freeze into the ice.
