Wrap thawing glaciers in football-field-size synthetic blankets that keep the cold in and the heat out. At least that's what ski resorts in the Swiss Alps are doing. Tired of risking the fate of their industry on the global community's ability to get a grip on rapid climate change, more than a dozen resorts turned to local textile company Fritz Landolt to stop the melting. Called the Ice Protector, Landolt's material is a tough but lightweight dual-layer composite. On top is polyester to reflect ultraviolet light, and on the bottom is polypropylene, a polymer used in military clothing and auto parts, to block heat. When wrapped around a glacier, it prevents the top snow layer-and, it's hoped, the permanent ice underneath-from melting in the summer sun.
