Download or read book Climate, Fire and Human Evolution written by Andrew Y. Glikson and published by Springer. This book was released on 2015-11-04 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book outlines principal milestones in the evolution of the atmosphere, oceans and biosphere during the last 4 million years in relation with the evolution from primates to the genus Homo – which uniquely mastered the ignition and transfer of fire. The advent of land plants since about 420 million years ago ensued in flammable carbon-rich biosphere interfaced with an oxygen-rich atmosphere. Born on a flammable Earth surface, under increasingly unstable climates descending from the warmer Pliocene into the deepest ice ages of the Pleistocene, human survival depended on both—biological adaptations and cultural evolution, mastering fire as a necessity. This allowed the genus to increase entropy in nature by orders of magnitude. Gathered around camp fires during long nights for hundreds of thousandth of years, captivated by the flickering life-like dance of the flames, humans developed imagination, insights, cravings, fears, premonitions of death and thereby aspiration for immortality, omniscience, omnipotence and the concept of god. Inherent in pantheism was the reverence of the Earth, its rocks and its living creatures, contrasted by the subsequent rise of monotheistic sky-god creeds which regard Earth as but a corridor to heaven. Once the climate stabilized in the early Holocene, since about ~7000 years-ago production of excess food by Neolithic civilization along the Great River Valleys has allowed human imagination and dreams to express themselves through the construction of monuments to immortality. Further to burning large part of the forests, the discovery of combustion and exhumation of carbon from the Earth’s hundreds of millions of years-old fossil biospheres set the stage for an anthropogenic oxidation event, affecting an abrupt shift in state of the atmosphere-ocean-cryosphere system. The consequent ongoing extinction equals the past five great mass extinctions of species—constituting a geological event horizon in the history of planet Earth.

Book Synopsis Evolution of the Atmosphere, Fire and the Anthropocene Climate Event Horizon by : Andrew Y. Glikson
Download or read book Evolution of the Atmosphere, Fire and the Anthropocene Climate Event Horizon written by Andrew Y. Glikson and published by Springer Science & Business Media. This book was released on 2013-10-08 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unique among all creatures, further to the increase in its cranial volume from Australopithecus to Homo sapiens, the use of tools and cultural and scientific creativity, the genus Homo is distinguished by the mastery of fire, which since about two million years ago has become its blueprint. Through the Holocene and culminating in the Anthropocene, the burning of much of the terrestrial vegetation, excavation and combustion of fossil carbon from up to 420 million years-old biospheres, are leading to a global oxidation event on a geological scale, a rise in entropy in nature and the sixth mass extinction of species.
Book Synopsis The Plutocene: Blueprints for a Post-Anthropocene Greenhouse Earth by : Andrew Yoram Glikson
Download or read book The Plutocene: Blueprints for a Post-Anthropocene Greenhouse Earth written by Andrew Yoram Glikson and published by Springer. This book was released on 2017-07-10 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents projections and blueprints of the future geologic period, climate and biosphere, based on our current understanding of the Earth’s history and recent developments in the atmosphere-ocean-cryosphere system. By the second decade of the 21st century it has become clear that, rather than channel its efforts into protecting its planetary biosphere and living species, Homo sapiens continues to sink its remaining resources into weapons, including nuclear missiles – thus increasing the risk of intentional or accidental spread of radioactive nuclides on land, oceans and atmosphere. With time, possibility becomes probability, and probability becomes certainty ‒ heralding a transition from the Anthropocene to a new geological period, named here as Plutocene after the element Plutonium. During the Plutocene the biosphere is dominated by elevated temperatures, analogous to the Pliocene (2.6 – 5.3 Ma ago) or the Miocene (5.3 - 23 Ma ago) when mean global temperatures were 2 to 4 degrees Celsius warmer and sea levels 20 to 40 meters higher than pre-industrial levels. High levels of radioactivity will persist for at least 20,000 years and acid oceans will severely limit biological activity to the hardiest species. Atmospheric CO2 higher than 500 ppm with residence time on the order of thousands of years will delay the subsequent glacial cycle. These factors restrict comparisons of the Plutocene with biosphere conditions during the Miocene and Pliocene periods, partly because the flora and fauna evolved more gradually during these periods, unlike the abrupt climate shift of state during the second half of the 20th century and first part of the 21st century. Following a long lull in biological activity dominated by radiation-resistant organisms, especially Arthropods, a resumption of glacial cycles and decline in radioactivity will lead to the re-emergence of descendants of burrowing mammals and other genera. Depending on the intensity of radioactive pollution, hunter-gatherer humans may survive in northern latitudes, relatively cold high-altitude mountain valleys and elevated volcanic islands. In some areas subsistence farming may be possible. A new cycle will commence.
Book Synopsis Encyclopedia of the Anthropocene by :
Download or read book Encyclopedia of the Anthropocene written by and published by Elsevier. This book was released on 2017-11-27 with total page 2280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Encyclopedia of the Anthropocene presents a currency-based, global synthesis cataloguing the impact of humanity’s global ecological footprint. Covering a multitude of aspects related to Climate Change, Biodiversity, Contaminants, Geological, Energy and Ethics, leading scientists provide foundational essays that enable researchers to define and scrutinize information, ideas, relationships, meanings and ideas within the Anthropocene concept. Questions widely debated among scientists, humanists, conservationists, politicians and others are included, providing discussion on when the Anthropocene began, what to call it, whether it should be considered an official geological epoch, whether it can be contained in time, and how it will affect future generations. Although the idea that humanity has driven the planet into a new geological epoch has been around since the dawn of the 20th century, the term ‘Anthropocene’ was only first used by ecologist Eugene Stoermer in the 1980s, and hence popularized in its current meaning by atmospheric chemist Paul Crutzen in 2000. Presents comprehensive and systematic coverage of topics related to the Anthropocene, with a focus on the Geosciences and Environmental science Includes point-counterpoint articles debating key aspects of the Anthropocene, giving users an even-handed navigation of this complex area Provides historic, seminal papers and essays from leading scientists and philosophers who demonstrate changes in the Anthropocene concept over time
Book Synopsis The Arctic in the Anthropocene by : National Research Council
Download or read book The Arctic in the Anthropocene written by National Research Council and published by National Academies Press. This book was released on 2014-07-31 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.
Book Synopsis The Evolution of Human Settlements by : William M. Bowen
Download or read book The Evolution of Human Settlements written by William M. Bowen and published by Palgrave Macmillan. This book was released on 2018-08-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the history and development of settlements—from the earliest periods in human history to the present day—from a Darwinian evolutionary perspective. At the foundation of the evolutionary model is the argument that the human capacity for complex communication and unique problem-solving ability have led to the formation and reality of the modern city and its scaled-up megacity status. While evolutionary theory forms the platform for the book’s argument, general systems theory provides the operational framework for the organization and interpretations of each chapter. Throughout the book, the authors tackle various issues, questions, and possibilities regarding the future development and evolution of human settlements.

Book Synopsis Climate Change and the Health of Nations by : Anthony J. McMichael
Download or read book Climate Change and the Health of Nations written by Anthony J. McMichael and published by Oxford University Press. This book was released on 2017 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: When we think of "climate change," we think of man-made global warming, caused by greenhouse gas emissions. But natural climate change has occurred throughout human history, and populations have had to adapt to the climate's vicissitudes. Anthony J. McMichael, a renowned epidemiologist and a pioneer in the field of how human health relates to climate change, is the ideal person to tell this story. Climate Change and the Health of Nations shows how the natural environment has vast direct and indirect repercussions for human health and welfare. McMichael takes us on a tour of human history through the lens of major transformations in climate. From the very beginning of our species some five million years ago, human biology has evolved in response to cooling temperatures, new food sources, and changing geography. As societies began to form, they too adapted in relation to their environments, most notably with the development of agriculture eleven thousand years ago. Agricultural civilization was a Faustian bargain, however: the prosperity and comfort that an agrarian society provides relies on the assumption that the environment will largely remain stable. Indeed, for agriculture to succeed, environmental conditions must be just right, which McMichael refers to as the "Goldilocks phenomenon." Global warming is disrupting this balance, just as other climate-related upheavals have tested human societies throughout history. As McMichael shows, the break-up of the Roman Empire, the bubonic Plague of Justinian, and the mysterious collapse of Mayan civilization all have roots in climate change. Why devote so much analysis to the past, when the daunting future of climate change is already here? Because the story of mankind�s previous survival in the face of an unpredictable and unstable climate, and of the terrible toll that climate change can take, could not be more important as we face the realities of a warming planet. This sweeping magnum opus is not only a rigorous, innovative, and fascinating exploration of how the climate affects the human condition, but also an urgent call to recognize our species' utter reliance on the earth as it is.
