Periglacial and paraglacial environments, located outside ice sheet margins but responding to similar climate forcings, are key to identifying climate change effects upon the Earth system. These environments are relicts of cold Earth processes and so are most sensitive to global warming. Changes in the distribution and thickness of permafrost in continental interiors have implications for ecosystem and landscape stability. Periglacial Alpine environments are experiencing increased rockfall and mass movement, leading to rock glacier instability and sediment release to downstream rivers. In turn, these landscape effects impact on natural hazards and human activities in these sensitive and geologically transient environments.

The Periglacial Environment, Fourth Edition, is an authoritative overview of the world’s cold, non-glacial environments. First published in 1976 and subsequently revised in 1996 and 2007, the text has been the international standard for nearly 40 years. The Fourth Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes and landforms that characterize periglacial environments. Part One discusses the periglacial concept and describes the typical climates and ecosystems that are involved. Part Two describes the geocryology (permafrost science) associated with frozen ground. Part Three outlines the weathering and geomorphic processes associated with cold-climate conditions. Part Four provides insight into the periglacial environments of the Quaternary, especially the Late Pleistocene. Part Five describes some of the problems associated with human occupancy in regions that experience frozen ground and cold-climate conditions. Extensively revised and updated Written by an expert with over 50 years of field research Draws upon the author’s personal experience from Northern Canada, Alaska, Siberia, Tibet, Antarctica, Svalbard, Scandinavia, southern South America, Western Europe and eastern North America This book is an invaluable reference for advanced undergraduates in geography, geology, earth sciences and environmental sciences programs, and to resource managers and geotechnical engineers interested in cold regions.

This book, originally published in 1980, provides a comprehensive overview of frost-action and mass-wasting processes and their effects, present and past. As warming of permafrost is becoming an increasingly important component of global climate change research, this text is also of increasing relevance. Geocryology is included in the title to emphasize the pervasive influence of ice and its phase changes in these processes. This book is neither a formal text nor a reference manual but something of both and a guide to the enormous literature. The text is illustrated with over 200 photographs and diagrams. The following topics are covered: Environmental factors, frozen ground, general frost-action processes, some periglacial forms, mass-wasting processes and forms, nivation, slopewash, fluvial action, lacrustine and marine action, wind action, thermokarst, environmental overview and environmental reconstructions. L. Washburn was the first executive director of the Arctic Institute of North America. He dedicated his life to fieldwork and the intensive study of the Arctic and Polar Regions in general, focusing on glacial and periglacial environments and Quaternary history of the earth. Dr. Washburn was Professor Emeritus in the department of Geological Sciences and the Quaternary Research Center at the University of Washington, and former Director of its Quaternary Research Center. He was deeply involved in the establishment of the journal Arctic and was founder and former Editor of Quaternary Research.

Understanding the sediments deposited by glaciers or other cold-climate processes assumes enhanced significance in the context of current global warming and the predicted melt and retreat of glaciers and ice sheets. This volume analyses glacial, proglacial and periglacial settings. Papers include topics such as sedimentation at termini of tidewater glaciers, poorly understood high-mountain features, and slope and aeolian deposits that have been sourced in glacial and periglacial regions and subsequently transported and deposited by azonal processes. Difficulties encountered in inferring Pleistocene and pre-Pleistocene cold-climate conditions when the sedimentary record lacks specific diagnostic indicators are discussed. The main objective of this volume is to establish the validity and limitations of the evidence that is used to achieve reliable palaeogeographic and palaeoclimatic reconstructions. On the much longer geological timescale, an understanding of ice-marginal and periglacial environments may better prepare us for the unavoidable reversal towards cooler and perhaps even glacial times in the future.

This book comprehensively presents the geography of landforms linked to periglacial processes across Europe. The landscape of the European cold climate regions, both at high latitudes and in mountainous environments, represent the lingering, minimal expression of the glaciers. In addition, periglacial elements can be found in temperate regions, where temperatures no longer favor periglacial processes, so landforms are therefore inherited from previous cold phases. The book is divided into five parts: an introductory section on climate variability responsible for periglacial dynamics across Europe; a second part including 3 blocks on periglacial landforms in southern, central and northern Europe; and a final chapter providing a more general perspective on the impact of periglacial processes on the landscape of Europe. The book offers a valuable reference guide for scientists from all disciplines interested in cold climate processes, as well as readers outside academia (territorial managers, environmentalists, mountaineers, politicians, engineers, etc.).

This 1987 book examines the intimate link between periglacial geomorphology and the fluctuating climates of the Quaternary Period in the British Isles. In the last two million years, ice sheets have covered northern Britain several times. In the south, at the limit of the glaciation, intense frost action and the formation of permafrost have influenced past and present landscapes. The first part of the book looks at areas of the world that have climates similar to periglacial Britain: Scandinavia, the Canadian Arctic, and alpine regions. Contributors then present data on periglacial landforms in the British Isles. Topics discussed include the periglaciation of upland Britain, ground ice depressions, and pingo remnants. The regions surveyed stretch from northern Scotland to the Isles of Scilly. The contributions are based on a conference held in late 1985 under the sponsorship of the International Geographical Union and the Quaternary Research Association of the United Kingdom.

Few subjects have caught the attention of the entire world as much as those dealing with natural hazards. The first decade of this new millennium provides a litany of tragic examples of various hazards that turned into disasters affecting millions of individuals around the globe. The human losses (some 225,000 people) associated with the 2004 Indian Ocean earthquake and tsunami, the economic costs (approximately 200 billion USD) of the 2011 Tohoku Japan earthquake, tsunami and reactor event, and the collective social impacts of human tragedies experienced during Hurricane Katrina in 2005 all provide repetitive reminders that we humans are temporary guests occupying a very active and angry planet. Any examples may have been cited here to stress the point that natural events on Earth may, and often do, lead to disasters and catastrophes when humans place themselves into situations of high risk. Few subjects share the true interdisciplinary dependency that characterizes the field of natural hazards. From geology and geophysics to engineering and emergency response to social psychology and economics, the study of natural hazards draws input from an impressive suite of unique and previously independent specializations. Natural hazards provide a common platform to reduce disciplinary boundaries and facilitate a beneficial synergy in the provision of timely and useful information and action on this critical subject matter. As social norms change regarding the concept of acceptable risk and human migration leads to an explosion in the number of megacities, coastal over-crowding and unmanaged habitation in precarious environments such as mountainous slopes, the vulnerability of people and their susceptibility to natural hazards increases dramatically. Coupled with the concerns of changing climates, escalating recovery costs, a growing divergence between more developed and less developed countries, the subject of natural hazards remains on the forefront of issues that affect all people, nations, and environments all the time. This treatise provides a compendium of critical, timely and very detailed information and essential facts regarding the basic attributes of natural hazards and concomitant disasters. The Encyclopedia of Natural Hazards effectively captures and integrates contributions from an international portfolio of almost 300 specialists whose range of expertise addresses over 330 topics pertinent to the field of natural hazards. Disciplinary barriers are overcome in this comprehensive treatment of the subject matter. Clear illustrations and numerous color images enhance the primary aim to communicate and educate. The inclusion of a series of unique “classic case study” events interspersed throughout the volume provides tangible examples linking concepts, issues, outcomes and solutions. These case studies illustrate different but notable recent, historic and prehistoric events that have shaped the world as we now know it. They provide excellent focal points linking the remaining terms in the volume to the primary field of study. This Encyclopedia of Natural Hazards will remain a standard reference of choice for many years.
