Global warming usually seems to happen far away, but one catastrophic effect of climate change is underway right now in the Rocky Mountains. In "The Melting World," Chris White travels to Montana to chronicle the work of Dan Fagre, a climate scientist and ecologist, whose work shows that alpine glaciers are vanishing rapidly close to home. For years, Fagre has monitored the ice sheets in Glacier National Park proving that they and by extension all Rocky Mountain ice will melt far faster than previously imagined. How long will the ice fields survive? What are the consequences on our environment? "The Melting World" chronicles the first extinction of a mountain ecosystem in what is expected to be a series of such global calamities as humanity faces the prospect of a world without alpine ice."
