Discussing the ways that scientists have observed and modeled glaciers, this volume tells how climate change is altering their size and distribution, and looks closely at their effect on human life. Glaciers are important water and energy sources for those living in mountains and adjacent lowlands, as well as increase the hazards of flooding and landslides. In addition to investigating these issues and considering an array of possible responses, the contributors assess the cultural and spiritual impact of glacier retreat in this timely, comprehensive work on one of the most urgent and conspicuous consequences of global warming.
