This book was released on 1996 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The magnitude and causes of decadal to century-scale changes in climate are major issues of global concern. The separation of anthropogenically driven change from natural 'baseline' variability within the atmosphere/ocean system is a prerequisite to identifying human impact on global climate. An understanding of past climate variability is therefore a key to predicting future climate change. The sedimentary record of the oceans, seas and lakes is produced by a series of depositional events that occur on seasonal timescales but can rarely be resolved due to mixing of the sediment by bottomdwelling organisms. Where they are preserved, laminated sediments act like tree rings to record these seasonal-scale processes, such as plankton blooms and floods, and provide a uniquely high-resolution record of environmental change. In addition, annually laminated or 'varved' sediment sequences act as geochronometers against which other timescales can be tested. Laminated sediments may therefore be used to develop records of interannual and decadal-scale variability which serve to test models of climate change. The authors cover a range of topics that include strategies for study and techniques of analysis. A series of case studies, dealing with a variety of lacustrine and marine records, illustrates the wide potential of laminated sediments as palaeoclimatic and palaeoceanographic indicators.

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.

Download or read book Reconstructing Human-Landscape Interactions written by Pam Dickinson and published by Cambridge Scholars Publishing. This book was released on 2009-03-26 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reconstructing Human-Landscape Interactions demonstrates the high quality of work presented at the first Developing International Geoarchaeology conference (DIG 2005), held in Saint John, New Brunswick, Canada, and exemplifies the over-riding theme of this discipline. People have always used the landscape in many ways: as a place to live, as a place to grow crops, as a source of natural resources. Those actions leave their traces. The characteristics of the landscape constrain which activities are possible, just as social and cultural habits condition people’s connection with the environment. Geoarchaeology is about finding the traces of these interactions, and using them to reconstruct how people in the past behaved in their environmental context. The material covered in the proceedings ranges from broad themes of climate change and landscape use, to more specific subjects such as river avulsion and the use of tidal ponds. The papers move us from the land to the coastal margin and back onto land to examine particular techniques. The final paper leads us beyond archaeology and points out that geoarchaeological data must contribute to the debate about the sustainability of present-day land-use practices: a fitting challenge to take us into the future.

This book was released on 2013-06-29 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous experts including ecologists, geneticists, paleontologists and climatologists, investigate the response of terrestrial organisms to changes in their environment. The volume comprises an introductory and a final chapter by the editors as well as another 35 contributions. These are divided into six sections: 1. past environmental changes - the late-Quaternary; 2. spatial responses to past changes; 3. mechanisms enabling spatial responses; 4. evolutionary responses to past changes; 5. mechanisms enabling evolutionary responses; 6. predicted future environmental changes and simulated responses. The overwhelming and unanimous conclusion of all contributors is that forecasted global environmental changes pose a severe threat to the integrity of ecosystems worldwide and to the survival of at least some species.

Download or read book Global Change in the Holocene written by John Birks and published by Routledge. This book was released on 2014-02-24 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Holocene spans the 11,500 years since the end of the last Ice Age and has been a period of major global environmental change. However the rate of change has accelerated during the last hundred years, due largely to human impacts and this has led to a growing concern for the future of our environmental resources. Global Change in the Holocene demonstrates how reconstructing the record of past environmental change can provide us with essential knowledge about how our environment works and presents the reader with an informed viewpoint from which to project realistic future scenarios. The book brings together key techniques that are widely used in Holocene research, such as radiocarbon dating, dendrochronology and sediment analysis and offers a comprehensive analysis of various archives of environmental change including instrumental and documentary records, corals, lake sediments, glaciers and ice cores. This reference will be an informative and cutting-edge resource for all researchers in the fields of climate change, environmental science, geography, palaeoecology and archaeology.

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 454 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

Download or read book Climate Change in North America written by George Ohring and published by Springer Science & Business Media. This book was released on 2014-02-12 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes thoroughly the North American Climate of the past 65 million years, with special emphasis on the last 21,000 years, as revealed by paleoclimatic observations and climate models. It analyzes weather observations over the past century and satellite measurements of the last few decades to develop a picture of more recent climatic trends. It explains how global climate models are used to simulate and project climate, and presents the application of these models to reproduce recent climate variations and predict future North American climate. It answers the critical question of whether observed climate change is due to natural variations or human activity.
