This book was released on 2011-01-10 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.

This book was released on 2019-06-18 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.

Download or read book Managing Water Resources in a Time of Global Change written by Alberto Garrido and published by Routledge. This book was released on 2009-01-13 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global change possesses serious challenges for water managers and scientists. In mountain areas, where water supplies for half of the world population originate, climate and hydrologic models are still subject to considerable uncertainty. And yet, critical decisions have to be taken to ensure adequate and safe water supplies to billions of people, millions of farmers and industries, without further deteriorating rivers and water bodies. While global warming is known to cause glaciers’ retreat and reduced snow packs around the world, it is not clear that mountain discharge will be lower. What is widely recognised is that water management must be adapted to accommodate significant regime changes. However, this inevitably involves managing transboundary rivers, adding further complexity to putting principles in practice. This book takes global warming and the importance of mountain areas in world water resources as the starting point. First, it provides detailed reviews of the processes going on in several rivers systems and world regions in Europe (Rhône and Ebro), North America (Canadian Rockies, Western US and Mexico), the Middle East (Jordan), Africa (Tunisia, Kenya and South Africa). These contexts provide case studies and examples that show the difficulties and potential for adaptation to global change. Land-use, economics, numerous modeling approaches are some of the cross-cutting issues covered in the chapters. The volume also includes the views of water practitioners, with two chapters authored by members of the US-Canada International Joint Commission, an industrialist from Western Canada and an environmental leader in Spain. By combining a rich set of contexts and approaches, the volume succeeds in offering a view of the global challenges faced by water agencies, international donors and researchers around the world. A case is made in some chapters to seek adaptive strategies rather than trying to reduce or control resources variability. This requires factoring in land-use, social and economic aspects, especially in developing countries. Another conclusion is that complex problems can and must be posed and negotiated with the help of models, mapping techniques and science-based facts. However complex these may be, there are ways to translate them to easily interpretable and visualisations of alternative scenarios and courses of action. This book provides numerous examples of the potential of such approaches to draft environmental programmes solve transboundary disputes and reduce the economic consequences of droughts and climate instability.

Download or read book Climate Change Effects on Groundwater Resources written by Holger Treidel and published by CRC Press. This book was released on 2011-12-02 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is expected to modify the hydrological cycle and affect freshwater resources. Groundwater is a critical source of fresh drinking water for almost half of the world’s population and it also supplies irrigated agriculture. Groundwater is also important in sustaining streams, lakes, wetlands, and associated ecosystems. But despite this, knowledge about the impact of climate change on groundwater quantity and quality is limited. Direct impacts of climate change on natural processes (groundwater recharge, discharge, storage, saltwater intrusion, biogeochemical reactions, chemical fate and transport) may be exacerbated by human activities (indirect impacts). Increased groundwater abstraction, for example, may be needed in areas with unsustainable or contaminated surface water resources caused by droughts and floods. Climate change effects on groundwater resources are, therefore, closely linked to other global change drivers, including population growth, urbanization and land-use change, coupled with other socio-economic and political trends. Groundwater response to global changes is a complex function that depends on climate change and variability, topography, aquifer characteristics, vegetation dynamics, and human activities. This volume contains case studies from diverse aquifer systems, scientific methods, and climatic settings that have been conducted globally under the framework of the UNESCO-IHP project Groundwater Resources Assessment under the Pressures of Humanity and Climate Change (GRAPHIC). This book presents a current and global synthesis of scientific findings and policy recommendations for scientists, water managers and policy makers towards adaptive management of groundwater sustainability under future climate change and variability.
Download or read book Land Surface Evaporation written by Thomas J. Schmugge and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: General circulation model (GCM) experiments in the late 1970's indicated that the climate is sensitive to variations in evaporation at the land surface. Thus, in the context of climate modeling, it became important to develop techniques which would realistically estimate the evaporation flux on land. Land Surface Evaporation: Measurement and Parameterization discusses strategies for the use of experimental data in developing and testing parameterization schemes of the evaporation flux in GCM's. The book reviews state-of-the-art techniques, such as remote sensing, which measure evaporation fluxes over continental surfaces. It evaluates their relevance with respect to the various spatial and temporal scales of interest. This book will provide researchers in climatology, meteorology, hydrology and water management, and remote sensing with a thorough overview of current research in land surface evaporation. It will also give young scientists insight into surface processes.
Download or read book Terrestrial Water Storage Across Scales written by John Thomas Reager and published by . This book was released on 2012 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terrestrial water storage is difficult to observe over large areas, and as a result, studies of the global water cycle under changing climate tend to focus on a few key methodologies: monitoring of the large-scale fluxes of precipitation, evaporation and discharge; modeling the relationship between runoff response and precipitation forcing; or applying limited in-situ data sets to generalize and scale behavior. With NASA's Gravity Recovery And Climate Experiment (GRACE) mission, hydrologists are finally able to study terrestrial water storage for large river basins (>200,000 km2) with monthly time resolution, opening what was previously an unobservable 'black box' in land-surface water dynamics. GRACE data are ideally suited for monitoring global water storage variability and classifying differences in basin water storage behavior that are relevant for global climate studies. In this research we explore global to regional scale applications of GRACE data that highlight the novelty, functionality and importance of these groundbreaking observations. First, we present a new metric for the monitoring of global water cycle health and energy expenditure - the time-series of Total Global Ocean Mass Anomaly and Total Global Land Mass Anomaly from NASA's Gravity Recovery and Climate Experiment - and show that this metric is heavily influenced by highly variable regional water cycle dynamics in a few global "wet spots". Second, we provide results of a statistical model of basin-averaged GRACE terrestrial water storage anomaly and Global Precipitation Climatology Project (GPCP) precipitation for the world's largest basins. Third, we combine new 1-degree GRACE storage observations with state-of-the-art global land-surface model representations of surface, canopy and snow water, to derive a 1-degree spatially variable sub-surface water storage anomaly time series with error estimates. We convolve this result with global estimates of porosity from FAO Harmonized Soil Database to estimate an effective global active soil depth range and changes during the GRACE record. Finally, terrestrial water storage anomaly from the Gravity Recovery and Climate Experiment (GRACE) and precipitation observations from the Global Precipitation Climatology Project (GPCP) are applied at the regional scale to show the usefulness of a remotely sensed, storage-based flood potential method.
