Download or read book The Climate of Past Interglacials written by F. Sirocko and published by Elsevier. This book was released on 2006-12-08 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, climate fluctuations, such as the Little Ice Age, show that interglacial climate chage in not entirely stable, but responds to even subtle changes in radiative forcing. Through research, it has been made clear that even an abrupt change of climate within years is not just a theoretical possibility but has in fact happened in the prehistoric past. It is therefore clear that in principal it could happen again. Human civilaization has exploded under the mild and relatively stable climatic conditions that have prevailed over the last 11,000 years. This book focuses on revisiting the past and to study climate and environment in a suite of experiments where boundary conditions are similar but not identical to today so we can learn about the climate-environment system, its sensitivity, thresholds and feedback. The palaeoclimate community holds an important key to scientific information on climate change that provides a basis for appropriate adaptation and mitigation strategies. The authors of this book have taken up this challenge and summarize their results in this special volume. It presents state-of-the-art science on new reconstructions from all spheres of the Earth System and on their synthesis, on methodological advances, and on the current ability of numerical models to simulate low and high frequency changes of climate, environment, and chemical cycling related to interglacials. * Summarizes important information on climate change, providing a basis for appropriate adaptation and mitigation strategies for human civilization * Reports on new reconstuctions on methodological advances, numerical models simulating low and high frequence changes, and chemical cycling related to interglacials * Incorporates palaeovegetaion and numerical modeling of climate and environmental and geochemical parameters to address regional feedback to global change with successful data-models

Book excerpt: Originally published by the Australian Institute of Aboriginal Studies, this facsimile edition of Professor Sylvia J. Hallam's classic 1975 work, Fire and Hearth, includes a substantial Afterword by the author, and a Preface by Emeritus Professor John Mulvaney. The book has been produced in light of the considerable new interest in the subject of Aboriginal land management before European settlement in Australia. *** "The land the English settled was not as God made it. It was as the Aborigines made it." Such is the challenging claim which opens Sylvia Hallam's majestic pioneer memoir on the interconnections between Aboriginal society, Country and the varied applications of deliberate firing. -- from the Preface by Professor John Mulvaney [Subject: History, Anthropology, Ethnography, Australian Studies, Aboriginal Studies, Land Conservation]
Download or read book Fynbos written by Nicky Allsopp and published by OUP Oxford. This book was released on 2014-09-18 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: South Africa's fynbos region has intrigued biologists for centuries. It has achieved iconic status as a locus of megadiversity and therefore a place to study the ecological underpinnings of massive evolutionary radiations. Researchers have made great advances over the past two decades in unravelling the complexities of fynbos ecology and evolution, and the region has contributed significant insights into the adaptive radiations of large lineages, conservation science, pollination biology, invasive plant biology, and palaeoanthropology. Lessons from the fynbos offer much of value for understanding the origin, maintenance, and conservation of diversity anywhere in the world. This book provides the first synthesis of the field for 20 years, bringing together the latest ecological and evolutionary research on the South African global biodiversity hotspots of the Greater Cape Floristic Region - the iconic fynbos and succulent karoo. It explores the historical and modern physical and biological environment of this region, the circumstances and processes which have fostered its remarkable biodiversity, and the role this diversity has played in the emergence of modern humans. It also discusses the challenges of contemporary management and conservation of the region's biodiversity in the face of accelerating global change.

Available in PDF, EPUB and Kindle. Book excerpt: "The study of climate today seems to be dominated by global warming, but these predictions of climatic models must be placed in their geological, paleo-climatic, and astronomical context to create a complete picture of the Earth's future climate. The Future of the World's Climate presents that perspective with data and projections that have emerged from more technologically advanced and accurate climate modeling"--Publisher's website.

Download or read book Climate Changes in the Holocene written by Eustathios Chiotis and published by CRC Press. This book was released on 2018-11-15 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights climate as a complex physical, chemical, biological, and geological system, in perpetual change, under astronomical, predominantly, solar control. It has been shaped to some degree through the past glaciation cycles repeated in the last three million years. The Holocene, the current interglacial epoch which started ca. 11,700 years ago, marks the transition from the Stone Age to the unprecedented cultural evolution of our civilization. Significant climate changes have been recorded in natural archives during the Holocene, including the rapid waning of ice sheets, millennial shifting of the monsoonal fringe in the northern hemisphere, and abrupt centennial events. A typical case of severe environmental change is the greening of Sahara in the Early Holocene and the gradual desertification again since the fifth millennium before present. Climate Changes in the Holocene: Impact, Adaptation, and Resilience investigates the impact of natural climate changes on humans and civilization through case studies from various places, periods, and climates. Earth and human society are approached as a complex system, thereby emphasizing the necessity to improve adaptive capacity in view of the anthropogenic global warming and ecosystem degradation. Features: Written by distinguished experts, the book presents the fundamentals of the climate system, the unparalleled progress achieved in the last decade in the fields of intensified research for improved understanding of the carbon cycle, climate components, and their interaction. Presents the application of paleoclimatology and modeling in climate reconstruction. Examines the new era of satellite-based climate monitoring and the prospects of reduced carbon dioxide emissions.

Download or read book Exact Exponential Algorithms written by Fedor V. Fomin and published by Springer Science & Business Media. This book was released on 2010-10-26 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a long time computer scientists have distinguished between fast and slow algo rithms. Fast (or good) algorithms are the algorithms that run in polynomial time, which means that the number of steps required for the algorithm to solve a problem is bounded by some polynomial in the length of the input. All other algorithms are slow (or bad). The running time of slow algorithms is usually exponential. This book is about bad algorithms. There are several reasons why we are interested in exponential time algorithms. Most of us believe that there are many natural problems which cannot be solved by polynomial time algorithms. The most famous and oldest family of hard problems is the family of NP complete problems. Most likely there are no polynomial time al gorithms solving these hard problems and in the worst case scenario the exponential running time is unavoidable. Every combinatorial problem is solvable in ?nite time by enumerating all possi ble solutions, i. e. by brute force search. But is brute force search always unavoid able? De?nitely not. Already in the nineteen sixties and seventies it was known that some NP complete problems can be solved signi?cantly faster than by brute force search. Three classic examples are the following algorithms for the TRAVELLING SALESMAN problem, MAXIMUM INDEPENDENT SET, and COLORING.

Download or read book The South Atlantic in the Late Quaternary written by Gerold Wefer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: The South Atlantic plays a critical role in the couplingofoceanic processes between the Antarctic and the lower latitudes. The Antarctic Ocean, along with the adjacent southern seas, is of substantial importance for global climate and for the distributionofwater masses because itprovides large regions ofthe world ocean with intermediate and bottom waters. In contrast to the North Atlantic, the Southern Ocean acts more as an "information distributor", as opposed to an amplifier. Just as the North Atlantic is influencedby the South Atlantic through the contributionofwarm surface water,the incomingsupply ofNADW - in the area of the Southern Ocean as Circumantarctic Deep Water - influences the oceanography ofthe Antarctic. The competing influences from the northern and southern oceans on the current and mass budget systems can be best studied in the South Atlantic. Not only do changes in the current systems in the eastern Atlantic high-production regions affect the energy budget, they also influence the nutrient inventories, and therefore impact the entire productivity ofthe ocean. In addition, the broad region of the polar front is a critical area with respect to productivity-related circulation since it is the source of Antarctic Intermediate Water. Although theAntarctic Intermediate Watertoday liesdeeper than the water that rises in the upwelling regions, it is the long-term source ofnutrients that are ultimately responsible for the supply oforganic matter to the sea floor and to sediments.
Download or read book Middle and Upper Paleolithic Sites in the Eastern Hemisphere written by Yoshihiro Nishiaki and published by Springer Nature. This book was released on 2023-09-23 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the archaeological sites and cultural assemblages in the world and presents an archaeological database that has been established through two large-scale research projects conducted between 2010 and 2022. The projects were Replacement of the Neanderthals by Modern Humans (2010–2015) and The Cultural History of PaleoAsia (2016–2022), both of which were carried out with the aid of the Japanese Government. They deal with multi-disciplinary studies of the demise of more archaic hominins and the survival of anatomically modern humans. Although the database is designated PaleoAsiaDB, which may imply a focus on Asia, it incorporates the dataset collected from Africa and Europe by the Replacement of the Neanderthals by Modern Humans project. PaleoAsiaDB provides a list of more than 3,300 sites and 7,600 cultural assemblages of the Middle and Upper Paleolithic (Middle and Late Stone Age) of the Eastern Hemisphere as of 2020. This database is the first attempt of its kind to document the related sites of 200-20ka. The full version of the database is available at the University Museum on the University of Tokyo homepage.
Download or read book The Archaeology of Australia s Deserts written by Mike Smith and published by Cambridge University Press. This book was released on 2013-02-25 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book-length study of the archaeology of Australia's deserts, one of the world's major habitats and the largest block of drylands in the southern hemisphere. Over the last few decades, a wealth of new environmental and archaeological data about this fascinating region has become available. Drawing on a wide range of sources, The Archaeology of Australia's Deserts explores the late Pleistocene settlement of Australia's deserts, the formation of distinctive desert societies, and the origins and development of the hunter-gatherer societies documented in the classic nineteenth-century ethnographies of Spencer and Gillen. Written by one of Australia's leading desert archaeologists, the book interweaves a lively history of research with archaeological data in a masterly survey of the field and a profoundly interdisciplinary study that forces archaeology into conversations with history and anthropology, economy and ecology, and geography and Earth sciences.
