"Information about ongoing glacier changes was already being collected internationally as early as 1894. In the beginning, the focus was on compiling and publishing findings relating to glacier front variations, in the hope that long-term glacier monitoring would give insight into processes affecting the formation of the Ice Ages. Since then, the datasets and goals of international glacier monitoring have evolved and multiplied. Glaciers have become the icon of global warming, which has resulted in an increasing demand for data and information about their global and regional distribution and changes. Modern monitoring strategies have been designed to provide quantitative and understandable information in connection with questions about process understanding, change detection, model calibration and validation, as well as environmental impacts. As such, monitoring can be regarded as the data backbone for scientific research. However, in spite of the early start of internationally coordinated glacier monitoring and its contemporaneous evolution within the glaciological sciences, the relevance of long-term glacier monitoring has not yet been fully acknowledged by the scientific community and funding agencies. It is to fill this gap in understanding that the present work undertakes to demonstrate the relevance of glacier monitoring, and its ability to complement scientific studies, on a local, mountain, and global scale. Based on 14 publications with essential contributions by this author, this work provides an overview of the historical background and present context of glacier monitoring, and the relevant organizations, strategies, and datasets. In the thematic main part, the methodological implementation of these concepts is presented, including exemplary results at different spatio-temporal scales integrating in-situ and remote sensing measurements, and numerical modeling. This is followed by a first effort to measure the relevance of internationally coordinated glacier monitoring. In this way, the present work provides a comprehensive summary of monitoring concepts, the results from recent distribution and glacier change studies, and an outlook on the corresponding key tasks for the coming decade(s). The internationally coordinated monitoring efforts over more than a century have resulted in an unprecedented dataset of information about spatial glacier distribution and changes over time. These datasets are readily available and include reconstructed glacier changes extending back into the Little Ice Age and the Holocene, direct observations of annual front variation dating back to the late 19th century, six decades of annual and seasonal mass balance measurements, and a preliminary world glacier inventory for the 1970s, based mainly on aerial photographs and maps, with detailed information on more than 100,000 glaciers. This latter inventory task continues through the present day, now based mainly on satellite images. These datasets document that the retreat from the Little Ice Age moraines is a worldwide and centennial trend showing increasing ice loss since the mid 1980s, with intermittent periods of glacier re-advances at regional and decadal scale. When looking at individual fluctuation series, one finds a high rate of variability and sometimes widely contrasting behavior of neighboring ice bodies. Reviewing the extensive literature available on process understanding and numerical modeling of glaciers, it becomes evident that, given current climate change scenarios, the ongoing trend of worldwide and rapid ice loss may lead to the deglaciation of large sectors of many mountain ranges during the present century. This will most probably trigger secondary impacts on global sea level rise, regional hydrologic regimes and landscape evolution, and local hazard situations beyond known historic and Holocene experience. Such rapid environmental changes require that the international glacier monitoring efforts make use of swiftly developing new technologies, such as remote sensing and geo-informatics, and relate them to the more traditional field observations, in order to tackle the challenges of the 21st century in a more effective way."

Provocative, passionate and populist, RMB Manifestos are short and concise non-fiction books of literary, critical, and cultural studies. Becoming Water takes the reader on a tour of Canada’s glaciers, describing the stories they tell and educating the reader about how glaciers came to be, how they work and what their future holds in our warming world. By visiting Canada’s high and low Arctic, and the mountain West, the reader will learn how varied and complex our glaciers really are, how they are measured and how they figure into the national and global story of inevitable change. The reader will learn to think like a scientist, in particular how to look at climate-related data that contains cycles, trends and shifts, and then ponder what questions to ask in the face of our dramatically changing environment. This book encourages Canadians to explore upstream from ourselves, learning about our origins and how climate change and encroaching human settlement are drastically impacting our glaciers and therefore the natural and human landscapes that lie below—and are dependent upon—them.

The earth’s cryosphere, which includes snow, glaciers, ice caps, ice sheets, ice shelves, sea ice, river and lake ice, and permafrost, contains about 75% of the earth’s fresh water. It exists at almost all latitudes, from the tropics to the poles, and plays a vital role in controlling the global climate system. It also provides direct visible evidence of the effect of climate change, and, therefore, requires proper understanding of its complex dynamics. This encyclopedia mainly focuses on the various aspects of snow, ice and glaciers, but also covers other cryospheric branches, and provides up-to-date information and basic concepts on relevant topics. It includes alphabetically arranged and professionally written, comprehensive and authoritative academic articles by well-known international experts in individual fields. The encyclopedia contains a broad spectrum of topics, ranging from the atmospheric processes responsible for snow formation; transformation of snow to ice and changes in their properties; classification of ice and glaciers and their worldwide distribution; glaciation and ice ages; glacier dynamics; glacier surface and subsurface characteristics; geomorphic processes and landscape formation; hydrology and sedimentary systems; permafrost degradation; hazards caused by cryospheric changes; and trends of glacier retreat on the global scale along with the impact of climate change. This book can serve as a source of reference at the undergraduate and graduate level and help to better understand snow, ice and glaciers. It will also be an indispensable tool containing specialized literature for geologists, geographers, climatologists, hydrologists, and water resources engineers; as well as for those who are engaged in the practice of agricultural and civil engineering, earth sciences, environmental sciences and engineering, ecosystem management, and other relevant subjects.

"Geologic Monitoring is a practical, nontechnical guide for land managers, educators, and the public that synthesizes representative methods for monitoring short-term and long-term change in geologic features and landscapes. A prestigious group of subject-matter experts has carefully selected methods for monitoring sand dunes, caves and karst, rivers, geothermal features, glaciers, nearshore marine features, beaches and marshes, paleontological resources, permafrost, seismic activity, slope movements, and volcanic features and processes. Each chapter has an overview of the resource; summarizes features that could be monitored; describes methods for monitoring each feature ranging from low-cost, low-technology methods (that could be used for school groups) to higher cost, detailed monitoring methods requiring a high level of expertise; and presents one or more targeted case studies."--Publisher's description.

This book comprises the main results of the Scenario (Support on Common European Strategy for sustainable natural and induced technological hazards mitigation) project, funded as a Specific Support Action under the VI FP. This book addresses three main needs: first, it constitutes an assessment of the situation of Europe as far as natural na-tech risks are considered; second, it suggests future research themes to be opened of widened so as to tackle new and emerging threats as well as changes in the potential response to risk governance, in order to improve the way scientific and technical expertise informs decision making regarding all fields of mitigation, ranging from structural to non structural measures, such as training, education and land use planning.
