A fascinating and authoritative overview of some of the world's cold non-glacial environments, with an emphasis on the North American and Eurasian polar, and mid-latitude lowlands. It describes the landforms and geomorphic processes which typify these environments. Divided into four parts, the book summarises the range and variability of periglacial climates, the main elements of periglacial landscape evolution, evidence for the existence of Pleistocene periglacial conditions in mid-latitudes and the current impact of human activity, including global warming.
