Download or read book Quaternary Glaciations Extent and Chronology written by J. Ehlers and published by Elsevier. This book was released on 2004-10-02 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the last of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial community, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimate modelling. In order to provide the information for the widest-possible range of users in the most accessible form, a series of digital maps was prepared. The glacial limits were mapped in ArcView, the Geographical Information System (GIS) used by the work group. Included with the publication is a CD with digital maps, showing glacial limits, end moraines, ice-dammed lakes, glacier-induced drainage diversions and the locations of key sections through which the glacial limits are defined and dated. Where controversial interpretations are possible, such as for High Asia, they are indicated. All information on Quaternary glaciations worldwide is presented for the first time in a uniform format, including the mountain glaciations of regions such as Costa Rica, Ethiopia or Taiwan. The digital maps in this volume cover Latin America, Asia, Africa, Australasia, Antarctica. Both overview maps and more detailed maps at a scale 1: 1,000,000 are provided.

Download or read book Water Environment and Society in Times of Climatic Change written by Arie S. Issar and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the greenhouse effect emerged as a predictable threat, necessitating the evalu ation of its future impact on the environment in the various parts of the globe, interest in the climate changes during the Holocene has gained momentum. The background can be summarized by the sentence: The past is a key to the future. As a matter of fact, this sentence is in the opposite direction, on the dimension of time, to the principle adopted by the founders of the science of geology. They proposed that geological processes in the present should be used as a key for understanding the past. Another reason for the interest in the history of the climate of the Holocene can be described as the renaissance of a modified deterministic approach to the inter relation between physical and human geography. This relates in the first place to the fact that various investigations, especially as carried out by Hubert Lamb, showed that the sequence of climate changes previously suggested by Blytt and Sernander for Europe and adopted by most Holocene climatologists was far too general, and that there were more climate changes during recent history than previously taken account of. In the second place it was found out that these changes had had an impact on the history of human communities. Thus, one can conclude that once the taboo on geographical determinism (i. e.
Download or read book Northern Forested Wetlands Ecology and Management written by Carl C. Trettin and published by Routledge. This book was released on 2018-12-19 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forested wetlands are a major component of northern landscapes, important both for their ecological functions and their socioeconomic values. Historically, these lands have been used for timber and fiber products, hunting, fishing, trapping, food gathering, and recreation. There are many questions about the use and management of these lands in the future, particularly with respect to forest products, hydrology and water quality, plant and wildlife ecology, landscape dynamics, and wetland restoration. Northern Forested Wetlands: Ecology and Management provides a synthesis of current research and literature. It examines the status, distribution, and use of these wetland resources. The book focuses on understanding the role of wetlands in the landscape and on how to manage these wetlands and sustain their important functions. This is a primary reference text for the study and management of northern forested wetlands, providing a forum for information discovered by researchers and managers from many nations.
Download or read book Sediment Records of Biomass Burning and Global Change written by James S. Clark and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass burning profoundly affects atmospheric chemistry, the carbon cycle, and climate and may have done so for millions of years. Bringing together renowned experts from paleoecology, fire ecology, atmospheric chemistry, and organic chemistry, the volume elucidates the role of fire during global changes of the past and future. Topics covered include: the characterization of combustion products that occur in sediments, including char, soot/fly ash, and polycyclic aromatic hydrocarbons; the calibration of these constituents against atmospheric measurements from wildland and prescribed fire emissions; spatial and temporal patterns in combustion emissions at scales of individual burns to the globe.

Download or read book Maize written by Duccio Bonavia and published by Cambridge University Press. This book was released on 2013-05-13 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines one of the thorniest problems of ancient American archaeology: the origins and domestication of maize. Using a variety of scientific techniques, Duccio Bonavia explores the development of maize, its adaptation to varying climates and its fundamental role in ancient American cultures. An appendix (by Alexander Grobman) provides the first-ever comprehensive compilation of maize genetic data, correlating this data with the archaeological evidence presented throughout the book. This book provides a unique interpretation of questions of dating and evolution, supported by extensive data, following the spread of maize from South to North America and eventually to Europe and beyond.

Download or read book Interhemispheric Climate Linkages written by Vera Markgraf and published by Elsevier. This book was released on 2001-01-25 with total page 484 pages. 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
