Just Wrap It Up in Some Tin Foil
They may not be able to do much about global warming, but the owners of a Swiss ski resort are saving their glacier the way you might save some old food: They're wrapping it in foil. Temperatures have been climbing, and the local glacier has been melting, endangering the resort's business. So the operators have unrolled a highly reflective type of foil over part of the ice formation. They're hoping to keep sunshine away from the ice.
