Download or read book Dendroclimatic Studies written by Rosanne D'Arrigo and published by John Wiley & Sons. This book was released on 2014-02-25 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: A top priority in climate research is obtaining broad-extent and long-term data to support analyses of historical patterns and trends, and for model development and evaluation. Along with directly measured climate data from the present and recent past, it is important to obtain estimates of long past climate variations spanning multiple centuries and millennia. Dendroclimatic Studies at the North American Tree Line presents an overview of the current state of dendroclimatology, its contributions over the past few decades, and its future potential. The material included is not useful not only to those who generate tree-ring records of past climate-dendroclimatologists, but also to users of their results-climatologists, hydrologists, ecologists and archeologists. In summary, this book: Sheds light on recent and future climate trends by assessing long term past climatic variations from tree rings Is a timely coverage of a crucial topic in climate science portraying recent warming trends which are of serious concern today Features well-reputed scientists highlighting new advanced methodologies to reconstruct past climate change Models the tree growth environmental response

Available in PDF, EPUB and Kindle. Book excerpt: A top priority in climate research is obtaining broad-extent and long-term data to support analyses of historical patterns and trends, and for model development and evaluation. Along with directly measured climate data from the present and recent past, it is important to obtain estimates of long past climate variations spanning multiple centuries and millennia. These longer time perspectives are needed for assessing the unusualness of recent climate changes, as well as for providing insight on the range, variation and overall dynamics of the climate system over time spans exceeding available records from instruments, such as rain gauges and thermometers. Tree rings have become increasingly valuable in providing this long-term information because extensive data networks have been developed in temperate and boreal zones of the Earth, and quantitative methods for analyzing these data have advanced. Tree rings are among the most useful paleoclimate information sources available because they provide a high degree of chronological accuracy, high replication, and extensive spatial coverage spanning recent centuries. With the expansion and extension of tree-ring data and analytical capacity new climatic insights from tree rings are being used in a variety of applications, including for interpretation of past changes in ecosystems and human societies. This volume presents an overview of the current state of dendroclimatology, its contributions over the last 30 years, and its future potential. The material included is useful not only to those who generate tree-ring records of past climate-dendroclimatologists, but also to users of their results-climatologists, hydrologists, ecologists and archeologists. ‘With the pressing climatic questions of the 21st century demanding a deeper understanding of the climate system and our impact upon it, this thoughtful volume comes at critical moment. It will be of fundamental importance in not only guiding researchers, but in educating scientists and the interested lay person on the both incredible power and potential pitfalls of reconstructing climate using tree-ring analysis.’, Glen M. MacDonald, UCLA Institute of the Environment, CA, USA ‘This is an up-to-date treatment of all branches of tree-ring science, by the world’s experts in the field, reminding us that tree rings are the most important source of proxy data on climate change. Should be read by all budding dendrochronology scientists.’, Alan Robock, Rutgers University, NJ, USA

Download or read book Tree rings and Climatic Changes in Western North America written by Edmund Schulman and published by . This book was released on 1953 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on about one-third million annual rings in selected, drought-sensitive trees from semi-arid sites, regional indices have been derived for the upper basins of all the major streams of the western United States. Almost all indices are statistically well-based for about 500 years; the Colorado and Missouri indices are well documented for about 800 years. Three series of maximum length are: Colorado, 2,009 years, including the extension in archaeological beams; Snake, 1494 years; Missouri, 973 years. A major element in the construction of these indices was the discovery and extensive sampling of a category of drought-recording, stunted conifers growing with extreme slowness on the most adverse sites and attaining ages twice or more the normal for the species on optimum growth sites. The oldest tree thus far discovered in each of the principal species is: limber pine, 1510 years; pinyon pine, 975 years; Rocky Mountain Douglas-fir, 880 years; ponderosa pine, 850 years. The much longer-lived Sequoia, growing in a relatively moist environment, were not sampled for this report.

Available in PDF, EPUB and Kindle. Book excerpt: The American Southwest is one of the most important archaeological regions in the world, with many of the best-studied examples of hunter-gatherer and village-based societies. Research has been carried out in the region for well over a century, and during this time the Southwest has repeatedly stood at the forefront of the development of new archaeological methods and theories. Moreover, research in the Southwest has long been a key site of collaboration between archaeologists, ethnographers, historians, linguists, biological anthropologists, and indigenous intellectuals. This volume marks the most ambitious effort to take stock of the empirical evidence, theoretical orientations, and historical reconstructions of the American Southwest. Over seventy top scholars have joined forces to produce an unparalleled survey of state of archaeological knowledge in the region. Themed chapters on particular methods and theories are accompanied by comprehensive overviews of the culture histories of particular archaeological sequences, from the initial Paleoindian occupation, to the rise of a major ritual center in Chaco Canyon, to the onset of the Spanish and American imperial projects. The result is an essential volume for any researcher working in the region as well as any archaeologist looking to take the pulse of contemporary trends in this key research tradition.

Download or read book The Natural West written by Dan Flores and published by University of Oklahoma Press. This book was released on 2003-03-30 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Natural West offers essays reflecting the natural history of the American West as written by one of its most respected environmental historians. Developing a provocative theme, Dan Flores asserts that Western environmental history cannot be explained by examining place, culture, or policy alone, but should be understood within the context of a universal human nature. The Natural West entertains the notion that we all have a biological nature that helps explain some of our attitudes towards the environment. FLores also explains the ways in which various cultures-including the Comanches, New Mexico Hispanos, Mormons, Texans, and Montanans-interact with the environment of the West. Gracefully moving between the personal and the objective, Flores intersperses his writings with literature, scientific theory, and personal reflection. The topics cover a wide range-from historical human nature regarding animals and exploration, to the environmental histories of particular Western bioregions, and finally, to Western restoration as the great environmental theme of the twenty-first century.

This book was released on 2013-06-29 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: A profound knowledge of the past climate is vital for our understanding of global warming. The past 2000 years are both the period which is of most relevance to the next century and that for which there is the most evidence. High-resolution proxy records for this period are available from a variety of sources. Five sections consider dendroclimatology, ice cores, corals, historical records, lake varves, and other indicators. The final two sections cover the histories of various forcing factors and attempt to bring together records from a variety of sources and provide explanations.

This book was released on 2005-11-10 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mesa Verde, Chaco Canyon, Canyon de Chelly, and Paquimé are well known to tourists and scholars alike as emblems of the American Southwest. This region has been the scene of intense archaeological investigations for more than a hundred years, with more research done here than in any other part of the United States. With contributions from well-known archaeologists, "Southwest Archaeology in the Twentieth Century" reviews the histories of major archaeological topics of the region during the twentieth century, giving particular attention to the vast changes in southwestern archaeology during the later decades of the century. Included are the huge influence of field schools, the rise of cultural resource management (CRM), the uses and abuses of ethnographic analogy, the intellectual contexts of archaeology in Mexico, and current debates on agriculture, sedentism, and political complexity. This book provides an authoritative retrospective of intellectual trends as well as a synthesis of current themes in the arena of the American Southwest. -- From publisher's description.
