Looking up at mountains, people now see bare, dark rock where white snow and ice once stood—dramatic evidence of the accelerating pace of glacier retreat due to climate change. This groundbreaking work is the first to provide an integrated, multidisciplinary, global exploration of the scientific, social, and economic dimensions of this phenomenon. Bringing together contributors from five continents, Darkening Peaks discusses the ways that scientists have observed and modeled glaciers, tells how climate change is altering their size and distribution, and looks closely at their effect on human life.
