Alaska lies squarely in the crosshairs of climate change. Glaciers are retreating. Permafrost is thawing. Coastal areas are eroding, washing away homes and history. The impact of climate change on Alaska's people, landscape, and wildlife is both dramatic and real. To understand these shifts, one must look not just at weather and nature but also at human activities. In this book, Michael Collier takes you to the far corners of Alaska to learn from scientists studying the effects of a changing climate and from people living with it day to day.
