Changing Planet: Melting Glaciers

As the Earth system warms due to rising levels of greenhouse gases in the atmosphere, observations show that land-based glaciers are melting fast in many places around the world - in the United States, Europe, South America, and Asia.  Because of ice-albedo feedback, as ice melts, albedo rises, producing further warming and faster melting.  Model predictions indicate that the remaining large glaciers in Glacier National Park will be gone by 2030.
