Global warming is likely to have the greatest impact at high latitudes, making the Arctic an important region both for detecting global climate change and for studying its effects on terrestrial ecosystems. The chapters in this volume address current and anticipated impacts of global climate change on Arctic organisms, populations, ecosystem structure and function, biological diversity, and the atmosphere.
