Available in PDF, EPUB and Kindle. Book excerpt: Climate change is producing profound changes globally. Yet we still know little about how it affects real people in real places on a daily basis because most of our knowledge comes from scientific studies that try to estimate impacts and project future climate scenarios. This book is different, illustrating in vivid detail how people in the Andes have grappled with the effects of climate change and ensuing natural disasters for more than half a century. In Peru's Cordillera Blanca mountain range, global climate change has generated the world's most deadly glacial lake outburst floods and glacier avalanches, killing 25,000 people since 1941. As survivors grieved, they formed community organizations to learn about precarious glacial lakes while they sent priests to the mountains, hoping that God could calm the increasingly hostile landscape. Meanwhile, Peruvian engineers working with miniscule budgets invented innovative strategies to drain dozens of the most unstable lakes that continue forming in the twenty first century. But adaptation to global climate change was never simply about engineering the Andes to eliminate environmental hazards. Local urban and rural populations, engineers, hydroelectric developers, irrigators, mountaineers, and policymakers all perceived and responded to glacier melting differently-based on their own view of an ideal Andean world. Disaster prevention projects involved debates about economic development, state authority, race relations, class divisions, cultural values, the evolution of science and technology, and shifting views of nature. Over time, the influx of new groups to manage the Andes helped transform glaciated mountains into commodities to consume. Locals lost power in the process and today comprise just one among many stakeholders in the high Andes-and perhaps the least powerful. Climate change transformed a region, triggering catastrophes while simultaneously jumpstarting modernization processes. This book's historical perspective illuminates these trends that would be ignored in any scientific projections about future climate scenarios.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The Himalayas of South Asia are home to many glaciers, which are retreating because of climate change and leaving in their wakes large lakes. These lakes are held in place by naturally deposited and inherently unstable moraine dams, which are at risk of overtop by impulse waves, commonly generated when avalanches or landslides enter the lake. When an overtopping event causes catastrophic failure, a glacial lake outburst flood (GLOF) occurs. The Imja glacier is experiencing the highest mass loss rate in the Mount Everest region, contributing to the expansion of Imja Tsho, a lake with several villages downstream. A GLOF from the lake can bring catastrophic damage to these villages, threatening both property and human life and creating a need to understand the processes that trigger these floods. The process chain for an avalanche-induced GLOF was modeled numerically, using the output of one subprocess as input into the next. First, the volume and momentum of various avalanches entering the lake were calculated using RAMMS. Next, the subsequent waves were simulated using BASEMENT software and validated with empirical equations to ensure the proper transfer of momentum from the avalanche to the lake. BASEMENT was then used to model moraine erosion and downstream flooding, which yielded a map of risk areas downstream. Moraine erosion was calculated for two geomorphologic scenarios: a site-specific scenario using field data, and a worst-case scenario based on past literature and applicable to lakes in the entire region. Neither case resulted in flooding outside the river channel at downstream villages. The worst-case scenario resulted in some moraine erosion and increased channelization of the lake outlet, which yielded greater discharge downstream but no catastrophic collapse. The site-specific scenario generated similar results, but with very little erosion and a smaller downstream discharge. Results indicated that Imja Tsho is unlikely to produce a catastrophic GLOF in the near future; however, some risk exists within the river channel, necessitating continued monitoring of the lake. Furthermore, these models were designed for ease and flexibility so that they can be adopted by a wide range of stakeholders and appropriated for other lakes in the region.

Download or read book Encyclopedia of Snow Ice and Glaciers written by Vijay P. Singh and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 1301 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. The Hindu Kush Himalayan region is the location of several of Asia's great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. Recent studies show that at lower elevations, glacial retreat is unlikely to cause significant changes in water availability over the next several decades, but other factors, including groundwater depletion and increasing human water use, could have a greater impact. Higher elevation areas could experience altered water flow in some river basins if current rates of glacial retreat continue, but shifts in the location, intensity, and variability of rain and snow due to climate change will likely have a greater impact on regional water supplies. Himalayan Glaciers: Climate Change, Water Resources, and Water Security makes recommendations and sets guidelines for the future of climate change and water security in the Himalayan Region. This report emphasizes that social changes, such as changing patterns of water use and water management decisions, are likely to have at least as much of an impact on water demand as environmental factors do on water supply. Water scarcity will likely affect the rural and urban poor most severely, as these groups have the least capacity to move to new locations as needed. It is predicted that the region will become increasingly urbanized as cities expand to absorb migrants in search of economic opportunities. As living standards and populations rise, water use will likely increase-for example, as more people have diets rich in meat, more water will be needed for agricultural use. The effects of future climate change could further exacerbate water stress. Himalayan Glaciers: Climate Change, Water Resources, and Water Security explains that changes in the availability of water resources could play an increasing role in political tensions, especially if existing water management institutions do not better account for the social, economic, and ecological complexities of the region. To effectively respond to the effects of climate change, water management systems will need to take into account the social, economic, and ecological complexities of the region. This means it will be important to expand research and monitoring programs to gather more detailed, consistent, and accurate data on demographics, water supply, demand, and scarcity.

Available in PDF, EPUB and Kindle. Book excerpt: The Himalaya mountains contain not only one of the largest concentrations of ice outside the polar regions, but contribute to the hydrological requirements of large populations spread over seven nations. The exceptionally high elevations of this low-latitude cryosphere presents a natural laboratory and archives to study climate–tectonics interactions as well as regional v. global climate influences. The existing base-level data on the Himalayan cryosphere are highly variable. Several climate fluctuations occurred during the late Quaternary (MIS1–MIS5, especially the last c. 100 ka), which led to the evolution of the Himalayan landscape. Detailed studies of these archives, along with those of the present cryosphere and related hydrosphere, are essential for understanding the controls on present and future hydrology of the glacial-fed mountain rivers. This volume, a follow-up of the XII International Symposium on Antarctic Earth Science, Goa (A SCAR symposium), provides new data from locales spread over the entire Himalaya region and from Tibet. It provides a glimpse of the late Quaternary cryosphere, as well as a discussion in the last section on sustainability in the context of geohazard mitigations as well as the hydrological budget.
