Climate change is happening twice as fast in the mountains as anywhere else, to devastating effects. Peaks are cracking. Landslides are more frequent. Ecosystems are disrupted. In a 950-mile journey from France to Slovenia (through Germany, Austria, Italy, and Switzerland), Nicolas Crunchant, a mountain guide with 30 years' experience, witnesses and heeds the mountains' lament, interviewing park rangers, scientists, and nature lovers. His book tackles the issue of climate change in the Alps from various perspectives, warning readers about the disaster looming even as we remain frozen in inaction.
