Book excerpt: The multi downscaled-scenario products allow us to better assess the uncertainty of the variations of precipitation and temperature in the current and future periods. Joint Probability distribution functions (PDFs), of both the climatic variables, might help better understand the interdependence of the two, and thus in-turn help in accessing the future with confidence. In the present study, we have used multi-modelled statistically downscaled ensemble of precipitation and temperature variables. The dataset used is multi-model ensemble of 10 Global Climate Models (GCMs) downscaled product from CMIP5 daily dataset, using the Bias Correction and Spatial Downscaling (BCSD) technique, generated at Portland State University. The multi-model ensemble PDFs of both precipitation and temperature is evaluated for summer (dry) and winter (wet) periods for 10 sub-basins across Columbia River Basin (CRB). Eventually, Copula is applied to establish the joint distribution of two variables on multi-model ensemble data. Results have indicated that the probabilistic distribution helps remove the limitations on marginal distributions of variables in question and helps in better prediction. The joint distribution is then used to estimate the change in trends of said variables in future, along with estimation of the probabilities of the given change. The joint distribution trends are varied, but certainly positive, for summer and winter time scales based on sub-basins. Dry season, generally, is indicating towards higher positive changes in precipitation than temperature (as compared to historical) across sub-basins with wet season inferring otherwise. Probabilities of changes in future, as estimated by the joint precipitation and temperature, also indicates varied degree and forms during dry season whereas the wet season is rather constant across all the sub-basins.

Book excerpt: Excerpt from A Climate-Change Scenario for the Columbia River Basin: Interior Columbia Basin Ecosystem Management Project: Scientific Assessment This work describes the method used to generate a climate-change scenario for the Columbia River Basin Ecosystem Management Project, which began in 1993. The project required an estimate of potential climate change to complement various scenarios of management alternatives. The scenario considers climate patterns that may change if the atmospheric concentration of carbon dioxide (co2), or its greenhouse gas equivalent, were to double over pre-industrial Revolution values. Given the current rate of increase in atmospheric C02 concentration, doubling could occur within the next 50 to 100 years. The Columbia River basin is in a transition climate zone between predominating maritime to the west, arctic to the north, and continental to the east. Consequently, it is difficult to characterize through means and averages. Therefore, many of the current stochastic methods for developing climate-change scenarios cannot directly apply to the basin. To circumvent this problem, a composite approach was taken to generate a climate scenario that considers knowledge of current regional climate controls, available output from general circulation and regional climate models, and observed changes in climate. The resulting climate-change scenario suggests that precipitation could increase substantially during winter to +50 percent) and moderately during spring and autumn to +35 percent). A slight decrease (o to -5 percent) in summer precipitation is possible, except for the southeastern portions of the basin that may experience an increase in convective precipitation percent). Low-elevation kilometer) temperatures throughout the year may increase 1 to 3 °c, with greatest increases during winter. This amount of temperature change is possible because of an expected loss of low-elevation snow cover. Warm temperatures and lack of low-elevation snow could reduce the magnitude of rain-on-snow floods. Wildfire potential could increase, however, as spring runoff from snowmelt is reduced. At high elevations, increased cloud cover could cause average temperatures to decrease during winter but be synchronized with possible warming at low elevations during summer. The diurnal range of temperature could decrease, especially in summer and autumn. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Aspects of climate that influence air quality in the Columbia River basin of the Northwestern United States are described. A few, relatively simple, analytical tools were developed to show the spatial and temporal patterns of mean-monthly mixing heights, precipitation scavenging, upper level and surface trajectory winds, and drought that inhibit pollution uptake. Also, potential changes in air quality from the effects of increasing greenhouse gases are discussed.

Book excerpt: We have found that the multi-model ensemble shows a consistent and significant increase in the extreme precipitation events in the west of the Cascades Range, Coastal Ranges of Oregon and Washington State, the Canadian portion of the basin and over the Rocky Mountains. However, the mean precipitation is projected to decrease in both winter and summer seasons in the future period.

Available in PDF, EPUB and Kindle. Book excerpt: Drought. Wildfire. Extreme flooding. How does climate change affect the daily work of scientists? Ecological restoration is often premised on the idea of returning a region to an earlier, healthier state. Yet the effects of climate change undercut that premise and challenge the ways scientists can work, destabilizing the idea of “normalcy” and revealing the politics that shape what scientists can do. How can the practice of ecological restoration shift to anticipate an increasingly dynamic future? And how does a scientific field itself adapt to climate change? Restoration efforts in the Columbia River Basin—a vast and diverse landscape experiencing warming waters, less snowpack, and greater fluctuations in precipitation—may offer answers to some of these questions. Shana Hirsch tells the story of restoration science in the basin, surveying its past and detailing the work of today’s salmon habitat restoration efforts. Her analysis offers critical insight into scientific practices, emerging approaches and ways of thinking, the incorporation of future climate change scenarios into planning, and the ultimate transformation—or adaptation—of the science of ecological restoration. For scientists and environmental managers around the globe, Anticipating Future Environments will shed light on how to more effectively cope with climate change.

This book was released on 2024-08-29 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change not only involves rising temperatures but it can also alter the hydro-meteorological parameters of a region and the corresponding changes emerging in the various biotic or abiotic environmental features. One of the results of climate change has been the impact on the sediment yield and its transport. These changes have implications for various other environmental components, particularly soils, water bodies, water quality, land productivity, sedimentation processes, glacier dynamics, and risk management strategies to name a few. This volume provides an overview of the fundamental processes and impacts of climate change on river basin management and examines issues related to soil erosion, sedimentation, and contaminants, as well as rainfall-runoff modeling and flood mitigation strategies. It also includes coverage of climate change fundamentals as well as chapters on related global treaties and policies.
