Download or read book Ice Ages Climate Dynamics and Biotic Events The Late Pennsylvanian World written by S.G. Lucas and published by Geological Society of London Special Publications. This book was released on 2023-06-19 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Late Pennsylvanian was a time of ice ages and associated climate dynamics. A major reduction in Gondwana ice-volume was followed by a prolonged period of relative global warmth, culminating in the last great ice age of the late Paleozoic. It also was a major turning point in the evolution of life on land, when the coal forests of the Middle Pennsylvanian gave way to new kinds of Late Pennsylvanian wetland vegetation, and new kinds of animals appeared. Changes in the terrestrial biota began during the Middle Pennsylvanian, accelerating and proceeding in a spatially complex manner throughout the Late Pennsylvanian. The Late Pennsylvanian is thus a laboratory for studying environmental changes in a glacial world, and for assessing coeval biotic changes, in part to establish the possible links between the two. No book has been dedicated to this time interval, so this volume fills a gap in our understanding of a dynamic Late Pennsylvanian world that is much like the late Cenozoic world.

Available in PDF, EPUB and Kindle. Book excerpt: There is little dispute within the scientific community that humans are changing Earth's climate on a decadal to century time-scale. By the end of this century, without a reduction in emissions, atmospheric CO2 is projected to increase to levels that Earth has not experienced for more than 30 million years. As greenhouse gas emissions propel Earth toward a warmer climate state, an improved understanding of climate dynamics in warm environments is needed to inform public policy decisions. In Understanding Earth's Deep Past, the National Research Council reports that rocks and sediments that are millions of years old hold clues to how the Earth's future climate would respond in an environment with high levels of atmospheric greenhouse gases. Understanding Earth's Deep Past provides an assessment of both the demonstrated and underdeveloped potential of the deep-time geologic record to inform us about the dynamics of the global climate system. The report describes past climate changes, and discusses potential impacts of high levels of atmospheric greenhouse gases on regional climates, water resources, marine and terrestrial ecosystems, and the cycling of life-sustaining elements. While revealing gaps in scientific knowledge of past climate states, the report highlights a range of high priority research issues with potential for major advances in the scientific understanding of climate processes. This proposed integrated, deep-time climate research program would study how climate responded over Earth's different climate states, examine how climate responds to increased atmospheric carbon dioxide and other greenhouse gases, and clarify the processes that lead to anomalously warm polar and tropical regions and the impact on marine and terrestrial life. In addition to outlining a research agenda, Understanding Earth's Deep Past proposes an implementation strategy that will be an invaluable resource to decision-makers in the field, as well as the research community, advocacy organizations, government agencies, and college professors and students.
Download or read book Discovering the Causes of the Ice Ages and Human Caused Climate Change a History of the Late Nineteenth and Early Twentieth Century written by Thomas Norris and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Human-caused climate change is a contentious issue today among some non-scientific communities who argue that scientists support climate change because of their political beliefs. In contrast, some historians today argue that the carbon dioxide hypothesis, which says that increased carbon dioxide in the air increases global temperatures and that much of the increase in carbon dioxide is due to human causes, was not taken seriously during the early twentieth century. These contradictory views led to my investigation of the history of human-caused climate change, which originally evolved out of the search in the late nineteenth and early twentieth century to find a cause(s) of the ice ages. This thesis investigates early research into the origin of the ice ages, which generated fourteen hypotheses, including the carbon dioxide hypothesis. Historically, climate change research included contributions from many scientific disciplines: astronomy, chemistry, geology, meteorology, and others.

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 Secrets of the Ice Ages written by Robert G. Johnson and published by Glenjay Pub. This book was released on 2002 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theme of the book is the connection between the cyclic ice ages shown by the marine geological records and the variations of received solar energy (insolation) due to changes in the earth's orbit and the earth's distance from the sun. The insolation variations modulate the African monsoons and storm activity, which alter Mediterranean salinity and outflow. The outflow modulates the oceanic conveyor belt which decisively influences the paths of storms bringing moisture to the ice-sheet areas. It is the moisture supply that governs the fate of the ice sheets rather than warmer or cooler climate, and the next ice age may be started in a few decades by a sharp increase in moisture delivered to the Canadian ice-sheet regions by storms. This narrative-style book is an easy read for anyone with a strong interest in climate change, and is a must for students and professionals in the earth-science fields.

This book was released on 1995-02-01 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: What can we expect as global change progresses? Will there be thresholds that trigger sudden shifts in environmental conditionsâ€"or that cause catastrophic destruction of life? Effects of Past Global Change on Life explores what earth scientists are learning about the impact of large-scale environmental changes on ancient lifeâ€"and how these findings may help us resolve today's environmental controversies. Leading authorities discuss historical climate trends and what can be learned from the mass extinctions and other critical periods about the rise and fall of plant and animal species in response to global change. The volume develops a picture of how environmental change has closed some evolutionary doors while opening othersâ€"including profound effects on the early members of the human family. An expert panel offers specific recommendations on expanding research and improving investigative toolsâ€"and targets historical periods and geological and biological patterns with the most promise of shedding light on future developments. This readable and informative book will be of special interest to professionals in the earth sciences and the environmental community as well as concerned policymakers.

This book was released on 2008-01-01 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This volume summarizes new developments in understanding the longest-lived icehouse period in Phanerozoic Earth history, the late Paleozoic ice age. Resolving the Late Paleozoic Ice Age in Time and Space provides summaries of existing and new data from the various Gondwanan continental relics, and also reviews stratigraphic successions from the paleotropical and temperate regions of Laurussia that preserve an indirect record of glaciation. It addresses the extent to which records of glaciation indicate protracted, long-term climatic austerity, as opposed to fluctuating, more dynamic climate, and provides new constraints on the timing of glaciation. Additionally, it tackles questions of synchroneity of glaciation across the various Gondwanan continental relics, and timing relationships between near-field and far-field records at greater levels of resolution than has been possible previously. Results point toward a dynamic icehouse regime that is comparable to the Cenozoic icehouse, and away from traditional interpretations of the late Paleozoic ice age as a single, protracted event that involved stable, long-lived ice centers."--Publisher's website.
