Rockglaciers are the visible expression of the creep of mountain permafrost. They are indicative of special geo-ecologic and geomorphic conditions regarding thermal situation, talus production, hydrology, and hazards in high mountain environments of all major mountain systems on earth. As relict features, they are of great paleoclimatic value. This book presents a systematic treatment of this landform in its environmental context.
An international team of over 150 experts provide up-to-date satellite imaging and quantitative analysis of the state and dynamics of the glaciers around the world, and they provide an in-depth review of analysis methodologies. Includes an e-published supplement. Global Land Ice Measurements from Space - Satellite Multispectral Imaging of Glaciers (GLIMS book for short) is the leading state-of-the-art technical and interpretive presentation of satellite image data and analysis of the changing state of the world's glaciers. The book is the most definitive, comprehensive product of a global glacier remote sensing consortium, Global Land Ice Measurements from Space (GLIMS, http://www.glims.org). With 33 chapters and a companion e-supplement, the world's foremost experts in satellite image analysis of glaciers analyze the current state and recent and possible future changes of glaciers across the globe and interpret these findings for policy planners. Climate change is with us for some time to come, and its impacts are being felt by the world's population. The GLIMS Book, to be released about the same time as the IPCC's 5th Assessment report on global climate warming, buttresses and adds rich details and authority to the global change community's understanding of climate change impacts on the cryosphere. This will be a definitive and technically complete reference for experts and students examining the responses of glaciers to climate change. World experts demonstrate that glaciers are changing in response to the ongoing climatic upheaval in addition to other factors that pertain to the circumstances of individual glaciers. The global mosaic of glacier changes is documented by quantitative analyses and are placed into a perspective of causative factors. Starting with a Foreword, Preface, and Introduction, the GLIMS book gives the rationale for and history of glacier monitoring and satellite data analysis. It includes a comprehensive set of six "how-to" methodology chapters, twenty-five chapters detailing regional glacier state and dynamical changes, and an in-depth summary and interpretation chapter placing the observed glacier changes into a global context of the coupled atmosphere-land-ocean system. An accompanying e-supplement will include oversize imagery and other other highly visual renderings of scientific data.
Though not traditionally thought of as strategic natural resources, glaciers are a crucial part of our global ecosystem playing a fundamental role in the sustaining of life around the world. Comprising three quarters of the world's freshwater, they freeze in the winter and melt in the summer, supplying a steady flow of water for agriculture, livestock, industry and human consumption. The white of glacier surfaces reflect sunrays which otherwise warm our planet. Without them, many of the planet's rivers would run dry shortly after the winter snow-melt. A single mid-sized glacier in high mountain environments of places like California, Argentina, India, Kyrgyzstan, or Chile can provide an entire community with a sustained flow of drinking water for generations. On the other hand, when global temperatures rise, not only does glacier ice wither away into the oceans and cease to act as water reservoirs, but these massive ice bodies can become highly unstable and collapse into downstream environments, resulting in severe natural events like glacier tsunamis and other deadly environmental catastrophes. But despite their critical role in environmental sustainability, glaciers often exist well outside our environmental consciousness, and they are mostly unprotected from atmospheric impacts of global warming or from soot deriving from transportation emissions, or from certain types of industrial activity such as mining, which has been shown to have devastating consequences for glacier survival. Glaciers: The Politics of Ice is a scientific, cultural, and political examination of the cryosphere -- the earth's ice -- and the environmental policies that are slowly emerging to protect it. Jorge Daniel Taillant discusses the debates and negotiations behind the passage of the world's first glacier-protection law in the mid-2000s, and reveals the tension that quickly arose between industry, politicians, and environmentalists when an international mining company proposed dynamiting three glaciers to get at gold deposits underneath. The book is a quest to educate general society about the basic science behind glaciers, outlines current and future risks to their preservation, and reveals the intriguing politics behind glacier melting debates over policies and laws to protect the resource. Taillant also makes suggestions on what can be done to preserve these crucial sources of fresh water, from both a scientific and policymaking standpoint. Glaciers is a new window into one of the earth's most crucial and yet most ignored natural resources, and a call to reawaken our interest in the world's changing climate.
These proceedings contain two hundred and eighteen papers representing the work of authors from countries across the world. They cover a wide range of research and applications in safety and reliability issues that concern all types of systems, processes and structures.
During the past few decades climatic geomorphology has been substantially enlarged in knowledge, thanks to numerous detailed investigations, the application of a large number of techniques, and the acquisition of abundant absolute dates. The challenge of predicting the effects of the prophesied future global warming on morphogenetic processes and landforms has encouraged geomorphologists to study the Late Pleistocene and Holocene climatic changes from the geomorphological and geological record. The advances achieved in the field of climatic geomorphology during the past years are reflected by the publication of several specific monographs about the different morphoclimatic zones. The aim of this book is to provide an up-to-date general view of this branch of geomorphology. It includes a chapter on applied geomorphology for each morphoclimatic zone providing an approximation of the main environmental problems. Geoscientists, geomorphologists
The Karakoram contains the greatest concentration of glaciers and most of the largest ice masses outside high latitudes. They comprise major stores and sources of fresh water in an otherwise extreme, continental, dry region. As many as 200 million people living downstream, in the valleys of the Indus and Yarkand Rivers, depend on melt waters from snow and ice. They are at risk from climate-change impacts on glaciers and water supply, and from hazards such as glacial lake outburst floods. Useful research initiatives go back to the nineteenth century, but coverage has generally been limited geographically and has not been continuous over time. It is almost 80 years since a monograph was devoted to the Karakoram glaciers. The book presents a comprehensive overview, including statistics for the ice cover, glacier mass balance and dynamics, glacierized landscapes, rock glaciers, water resources and environmental hazards. Published glaciological and related research is surveyed along with expedition reports and archival materials in several languages. The expanding potential of satellite coverage is exploited, but conditions and processes reported from field investigations are the main focus. Previously unpublished observations by the author are presented, based on some 45 years of work in the region. Broad understanding of the glacial environment is used to address emerging concerns about the High Asian cryosphere and the fate of its glaciers. These are discussed in relation to the pressing issues of water supply, environmental risk and sustainability. Questions of what is not known help identify much needed monitoring and research. The book is of interest to researchers, professionals, and those studying glaciers, mountain environments, water resources and environmental hazards. The topics discussed should be of concern for anyone involved in regional development and global change in South and Inner Asia.
This book, first published in 1992, contains the proceedings of the 22nd Binghamton Geomorphology Symposium, and highlights the quantity and diversity of periglacial geomorphic research being undertaken in Arctic and alpine environments. The articles explore a variety of geomorphic processes and examine the potential impacts of global change on the nature and extent of permafrost and seasonal ice phenomena.
European Glacial Landscapes: The Holocene presents the current state of knowledge on glacial landscapes of Europe and nearby areas over the Holocene to deduce the influence of atmospheric and oceanic currents and the insolation forcing variability and volcanic activity on Holocene paleoclimates, the existence of asynchronies in the timing of occurrence of glacier expansion and shrinkage during the Holocene, time lags between the identification of oceanic and atmospheric changes and those occurring in glacial extension during the Holocene, the role of Holocene glaciers on the climate of Europe, and on sea level variability, and the delimitation of landscapes that need special protection. Students, academics and researchers in Geography, Geology, Environmental Sciences, Physics and Earth Science departments will find this book provides novel findings of all the major European Regions in a single publication, with updated information about Holocene glacial geomorphology and paleo-climatology and clear figures that model the landscapes covered. - Provides a synthesis and summary of glacial processes in Europe over the Holocene period - Features research from experts in palaeo-climatology, palaeo-oceanography and palaeo-glaciology - Includes access to a companion website with an interactive map, photos of glacial features, and geospatial data related to European Glacial Landscapes
