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: 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 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Review of the Columbia River Treaty between the United States and Canada presents an opportunity to consider how governance might be made more adaptive in the face of climate change while maintaining an appropriate level of stability. Climate change scenarios applied to the Columbia River Basin predict an increasing water deficit due primarily to change in timing of runoff and increased demand as the result of warming. Current uses that will suffer the most from change in timing of runoff are those dependent on late summer flow - fish and farmers. The intersection of climate change with normal climate variability also suggests greater extremes that will require planning for both drought and flood beyond the historic recurrence and magnitude. A problem-solving approach to bridge the gap between the status quo and a modernized system must be combined with new approaches to governance that are both more flexible and more responsive to change if the basin is to navigate the future. This challenges not only the conventional wisdom that regulatory stability is essential to economic stability and achievement of societal goals, but the existing distribution of benefits among powerful players in the basin. Yet the goals of even the current recipients of benefits will not be met if a rigid approach is maintained as climate change unfolds. Adaptive water governance requires attention to institutional structure, introduction of adaptive authority and local participatory capacity including knowledge building, and process design that balances stability with flexibility. Models for implementation of these factors are found in international law and provide a pathway to adaptation to climate change through a modernized transboundary water agreement on the Columbia River.

This book was released on 2015 with total page 84 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Flows of the Columbia River, although modified substantially during the twentieth century, still vary considerably between seasons and between years. Lowest flows tend to occur during summer months when demand for irrigation water is at its highest and when water temperatures are greatest. These periods of low flows, high demand, and high temperature are critical periods for juvenile salmon migrating downstream through the Columbia River hydropower system. Although impacts on salmon of any individual water withdrawal may be small, the cumulative effects of numerous withdrawals will affect Columbia River flows and would pose increased risks to salmon survival. The body of scientific knowledge explaining salmon migratory behavior and physiology is substantial, but imperfect, and decision makers should acknowledge this and be willing to take action in the face of uncertainties. In order to provide a more comprehensive water permitting process, the State of Washington, Canada, other basin states, and tribal groups should establish a basin-wide forum to consider future water withdrawal application permits. If the State of Washington issues additional permits for water withdrawals from the Columbia River, those permits should contain provisions that allow withdrawals to be curtailed during critical high-demand periods.

Available in PDF, EPUB and Kindle. Book excerpt: The Columbia River Treaty: A Primer is a vital work that clearly explains the nature of this complex water agreement between Canada and the United States and how its impending update will impact communities, landscapes, industry and water supplies between the two countries for many years to come. The Columbia River Treaty ratification in 1964 created the largest hydropower project in North America, with additional emphasis on flood protection for the USA. As the Treaty approaches its 60th anniversary, and the first opportunity for modification, its signatories are preparing proposals for new ways forward, and stakeholders on both sides of the border are speaking up. This primer explores the initial intent of the Treaty and its success to date, its costs to Columbia Basin residents and ecosystems, and new influences the signatories must now consider. Shifts in social norms related to the environment, equity and social justice, new views on the relevance of Indigenous traditional and local knowledge, and the economic and physical effects of a changing climate—are all considered as factors in future Treaty governance. The primer concludes with a summary of the perspectives that currently exist between and within each country with respect to Treaty benefits and outlines the next steps that will take place in the negotiation process. The authors conclude with a call to action, in the hope that a renewed Columbia River Treaty might prove a model for outstanding transboundary water agreements around the world as they strive to meet not only the challenges of the present day but also the needs of future generations.
