This book was released on 2014-11-25 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study brings together decades of research on the modern natural environment of Washington's Olympic Peninsula, reviews past research on paleoenvironmental change since the Late Pleistocene, and finally presents paleoecological records of changing forest composition and fire over the last 14,000 years. The focus of this study is on the authors’ studies of five pollen records from the Olympic Peninsula. Maps and other data graphics are used extensively. Paleoecology can effectively address some of these challenges we face in understanding the biotic response to climate change and other agents of change in ecosystems. First, species responses to climate change are mediated by changing disturbance regimes. Second, biotic hotspots today suggest a long-term maintenance of diversity in an area, and researchers approach the maintenance of diversity from a wide range and angles (CITE). Mountain regions may maintain biodiversity through significant climate change in ‘refugia’: locations where components of diversity retreat to and expand from during periods of unfavorable climate (Keppel et al., 2012). Paleoecological studies can describe the context for which biodiversity persisted through time climate refugia. Third, the paleoecological approach is especially suited for long-lived organisms. For example, a tree species that may typically reach reproductive sizes only after 50 years and remain fertile for 300 years, will experience only 30 to 200 generations since colonizing a location after Holocene warming about 11,000 years ago. Thus, by summarizing community change through multiple generations and natural disturbance events, paleoecological studies can examine the resilience of ecosystems to disturbances in the past, showing how many ecosystems recover quickly while others may not (Willis et al., 2010).

Download or read book Review of the Draft Fourth National Climate Assessment written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-06-18 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

Download or read book Saving Forest Ecosystems written by Robert L. Edmonds and published by Archway Publishing. This book was released on 2021-02-02 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the first Euro-American settlers arrived in Seattle in the 1850s, the surrounding old-growth forests were rapidly harvested for lumber, causing environmental degradation and displacing native peoples. Conflicts about the future of Pacific Northwest forests have continued since then. Only recently have academics, government agencies, industry, small private landowners, tribes, and environmental organizations come together to develop plans to protect the remaining old-growth forests, wildlife, streams, and fish, as well as providing environmentally friendly forest products. Practicing sustainable forestry, maintaining healthy forests that are less susceptible to fire, insects and diseases; and fostering public enjoyment are now the main goals of forest management. However, conflicts still exist—and with climate change a looming threat, it is important to realize that forests give us much more than lumber. Robert L. Edmonds, professor emeritus at the School of Environmental and Forest Sciences, University of Washington (UW), wrote this book to bring attention to the sustainability of natural resources. He describes how Washington State’s forests and the practice of forestry have changed through time and how these changes relate to the long history of research and teaching at the UW. Its scope extends beyond Washington—many of the principles of sustainable forestry developed by faculty have been adopted worldwide.
Download or read book North Pacific Environment and Paleoclimate from the Late Pleistocene to Present written by Miriam Jones and published by Frontiers Media SA. This book was released on 2020-01-13 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast area of the North Pacific, spanning ~55˚ longitude, represents a challenge for documenting and understanding the geologic history of ocean, atmosphere, and terrestrial environmental change. Nevertheless, its importance for many issues, including our fundamental understanding of ocean and atmospheric circulation patterns and teleconnections with natural modes of climate variability through time, has led to a steady rise in the numbers of study sites and proxy types. By bringing together a wide range of proxies and timescales that examine the impacts of paleoclimate on ecosystems, water, carbon, and humans, and interactions between marine and terrestrial processes, this Research Topic contributes to an improved understanding of the region’s significance at global, hemispheric, and regional scales.

Download or read book First Peoples in a New World written by David J. Meltzer and published by Cambridge University Press. This book was released on 2021-10-07 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 15,000 years ago, a band of hunter-gatherers became the first people to set foot in the Americas. They soon found themselves in a world rich in plants and animals, but also a world still shivering itself out of the coldest depths of the Ice Age. The movement of those first Americans was one of the greatest journeys undertaken by ancient peoples. In this book, David Meltzer explores the world of Ice Age Americans, highlighting genetic, archaeological, and geological evidence that has revolutionized our understanding of their origins, antiquity, and adaptation to climate and environmental change. This fully updated edition integrates the most recent scientific discoveries, including the ancient genome revolution and human evolutionary and population history. Written for a broad audience, the book can serve as the primary text in courses on North American Archaeology, Ice Age Environments, and Human evolution and prehistory.
Download or read book Tectonics Climate and Landscape Evolution written by Sean D. Willett and published by Geological Society of America. This book was released on 2006-01-01 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Liwu River runs a short course; its channel head at the water divide in Taiwan's Central Range is a mere 35 km from its outflow into the Pacific Ocean. But in those short 35 km, the Liwu has carved one of the world's geographic wonders: the spectacular Taroko Gorge with marble and granite walls soaring nearly 1000 m above the river channel. Taroko Gorge was a fitting venue for a 2003 Penrose Conference that addressed the coupled processes of tectonics, climate, and landscape evolution. The young mountains, extreme weather, and dramatic landforms provided an appropriate backdrop to wide-ranging discussions of geomorphic processes, climate and meteorology, sediment generation and transport, the effects of erosion on tectonics, and new analytical and modeling tools used to address these processes and problems. This volume's papers extend that discussion, reaching across fields that have experienced rapid advances in the past decade."--Publisher's website.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a novel approach in the field of global change by presenting a comprehensive analysis of interhemispheric linkages of climate, present and past, and their effects on human societies. The ultimate goal of this interhemispheric integration is to improve our understanding of causes and mechanisms of climate change to enhance our capability in predicting future changes. Given the societal interest in global change issues this book offers a new approach for the integration of global information. It will provide a reference for professional scientists, researchers and graduate students in the fields of climatology, and the earth and environmental sciences. Chapters analyse instrumental atmospheric and oceanic data to address such phenomena as El Nino/Southern Oscillation variability and other climate anomalies such as the Pacific and North Atlantic Oscillation and polar air outbreaks A new systematic methodology is presented that allows objective and verifiable reconstruction of climate fields from sparse data Especially valuable in the context of climate proxy data
Download or read book Climate Change at the Pleistocene Holocene Boundary in the Pacific Northwest written by Tiffany J. Fulkerson and published by . This book was released on 2012 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The relationship between climate change at the Pleistocene-Holocene Boundary (ca. 12,600-10,200 cal B.P.) and cultural responses to attendant shifts in the environment remains a vexing issue for archaeologists. This study compiles and analyzes glacial, palynological, faunal, and stratigraphic/geomorphological proxy datasets for climate change in the Pacific Northwest of North America and compares them to the coeval archaeological record. The primary purpose of this exercise is to consider the potential ways in which climate change at the Pleistocene-Holocene Boundary affected cultural development for Late Paleoindian-Early Archaic peoples in the Pacific Northwest. Results indicate that climatic and environmental change at this interval was rapid or abrupt, and of a magnitude that likely produced varying adaptational responses by peoples of different cultural traditions who appear across the region at this period. Transformations in tools and technology, shifts in dietary habits, migration and regionalization, and trade intensification are all elements of Late Paleoindian-Early Archaic cultural responses to rapid climate change"--Document.
Download or read book Trekking the Shore written by Nuno F. Bicho and published by Springer Science & Business Media. This book was released on 2011-05-19 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human settlement has often centered around coastal areas and waterways. Until recently, however, archaeologists believed that marine economies did not develop until the end of the Pleistocene, when the archaeological record begins to have evidence of marine life as part of the human diet. This has long been interpreted as a postglacial adaptation, due to the rise in sea level and subsequent decrease in terrestrial resources. Coastal resources, particularly mollusks, were viewed as fallback resources, which people resorted to only when terrestrial resources were scarce, included only as part of a more complex diet. Recent research has significantly altered this understanding, known as the Broad Spectrum Revolution (BSR) model. The contributions to this volume revise the BSR model, with evidence that coastal resources were an important part of human economies and subsistence much earlier than previously thought, and even the main focus of diets for some Pleistocene and early Holocene hunter-gatherer societies. With evidence from North and South America, Europe, Africa, Asia, and Australia, this volume comprehensively lends a new understanding to coastal settlement from the Middle Paleolithic to the Middle Holocene.
