For the past 8 years, residents of the Swiss Alps have been wrapping glaciers in white blankets in order to reflect sunlight and reduce seasonal melting. David Volken, a Swiss glaciologist, told Agence France-Press that this method is probably working and may reduce melting by as much as 70%. This approach of covering glaciers with reflective material has also been in used in Italy and Germany, and some glaciologists started advocating for covering sections of the Greenland ice sheet in 2009.
