Book Synopsis Atmospheric Methane by : Mohammad Aslam Khan Khalil
Download or read book Atmospheric Methane written by Mohammad Aslam Khan Khalil and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane is an important greenhouse gas that can cause global warming. The present concentrations of methane are nearly three times higher than several hundred years ago. Today, more than 60% of the atmospheric methane comes from human activities, including rice agriculture, coal mining, natural gas usage, biomass burning, and raising of cattle. Methane affects the stratospheric ozone layer and the oxidizing capacity of the atmosphere, which in turn control the concentrations of many man-made and natural gases in the atmosphere. This book brings together our knowledge of the trends and the causes behind the increased levels of methane. Based on the scientific information on the sources and sinks, and the role of methane in global warming, strategies to limit emissions can be designed as part of a program to control future global warming.

Book Synopsis Improving Characterization of Anthropogenic Methane Emissions in the United States by : National Academies of Sciences, Engineering, and Medicine
Download or read book Improving Characterization of Anthropogenic Methane Emissions in the United States written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-08-25 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding, quantifying, and tracking atmospheric methane and emissions is essential for addressing concerns and informing decisions that affect the climate, economy, and human health and safety. Atmospheric methane is a potent greenhouse gas (GHG) that contributes to global warming. While carbon dioxide is by far the dominant cause of the rise in global average temperatures, methane also plays a significant role because it absorbs more energy per unit mass than carbon dioxide does, giving it a disproportionately large effect on global radiative forcing. In addition to contributing to climate change, methane also affects human health as a precursor to ozone pollution in the lower atmosphere. Improving Characterization of Anthropogenic Methane Emissions in the United States summarizes the current state of understanding of methane emissions sources and the measurement approaches and evaluates opportunities for methodological and inventory development improvements. This report will inform future research agendas of various U.S. agencies, including NOAA, the EPA, the DOE, NASA, the U.S. Department of Agriculture (USDA), and the National Science Foundation (NSF).
Book Synopsis Methane and Climate Change by : Dave Reay
Download or read book Methane and Climate Change written by Dave Reay and published by Routledge. This book was released on 2010-08-12 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane is a powerful greenhouse gas and is estimated to be responsible for approximately one-fifth of man-made global warming. Per kilogram, it is 25 times more powerful than carbon dioxide over a 100-year time horizon -- and global warming is likely to enhance methane release from a number of sources. Current natural and man-made sources include many where methane-producing micro-organisms can thrive in anaerobic conditions, particularly ruminant livestock, rice cultivation, landfill, wastewater, wetlands and marine sediments. This timely and authoritative book provides the only comprehensive and balanced overview of our current knowledge of sources of methane and how these might be controlled to limit future climate change. It describes how methane is derived from the anaerobic metabolism of micro-organisms, whether in wetlands or rice fields, manure, landfill or wastewater, or the digestive systems of cattle and other ruminant animals. It highlights how sources of methane might themselves be affected by climate change. It is shown how numerous point sources of methane have the potential to be more easily addressed than sources of carbon dioxide and therefore contribute significantly to climate change mitigation in the 21st century.
Book Synopsis Atmospheric Methane: Sources, Sinks, and Role in Global Change by : M.A.K. Khalil
Download or read book Atmospheric Methane: Sources, Sinks, and Role in Global Change written by M.A.K. Khalil and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methane plays many important roles in the earth's environment. It is a potent "greenhouse gas" that warms the earth; controls the oxidizing capacity of the atmosphere (OH) indirectly affecting the cycles and abundances of many atmospheric trace gases; provides water vapor to the stratosphere; scavenges chlorine atoms from the stratosphere, terminating the catalytic ozone destruction by chlorine atoms, including the chlorine released from the man-made chlorofluorocarbons; produces ozone, CO, and CO2 in the troposphere; and it is an index of life on earth and so is present in greater quantities during warm interglacial epochs and dwindles to low levels during the cold of ice ages. By all measures, methane is the second only to CO2 in causing future global warming. The book presents a comprehensive account of the current understanding of atmospheric methane, and it is an end point for summarizing more than a decade of intensive research on the global sources, sinks, concentrations, and environmental role of methane.

Book Synopsis Plows, Plagues, and Petroleum by : William F. Ruddiman
Download or read book Plows, Plagues, and Petroleum written by William F. Ruddiman and published by Princeton University Press. This book was released on 2016-10-04 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact on climate from 200 years of industrial development is an everyday fact of life, but did humankind's active involvement in climate change really begin with the industrial revolution, as commonly believed? Plows, Plagues, and Petroleum has sparked lively scientific debate since it was first published--arguing that humans have actually been changing the climate for some 8,000 years--as a result of the earlier discovery of agriculture. The "Ruddiman Hypothesis" will spark intense debate. We learn that the impact of farming on greenhouse-gas levels, thousands of years before the industrial revolution, kept our planet notably warmer than if natural climate cycles had prevailed--quite possibly forestalling a new ice age. Plows, Plagues, and Petroleum is the first book to trace the full historical sweep of human interaction with Earth's climate. Ruddiman takes us through three broad stages of human history: when nature was in control; when humans began to take control, discovering agriculture and affecting climate through carbon dioxide and methane emissions; and, finally, the more recent human impact on climate change. Along the way he raises the fascinating possibility that plagues, by depleting human populations, also affected reforestation and thus climate--as suggested by dips in greenhouse gases when major pandemics have occurred. While our massive usage of fossil fuels has certainly contributed to modern climate change, Ruddiman shows that industrial growth is only part of the picture. The book concludes by looking to the future and critiquing the impact of special interest money on the global warming debate. In the afterword, Ruddiman explores the main challenges posed to his hypothesis, and shows how recent investigations and findings ultimately strengthen the book's original claims.

Book Synopsis Methane Hydrates in Quaternary Climate Change by : James P. Kennett
Download or read book Methane Hydrates in Quaternary Climate Change written by James P. Kennett and published by American Geophysical Union. This book was released on 2003-01-10 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent discoveries from ice-core and marine sediments suggest that global climate systems can change from glacial to near-interglacial temperatures within decades. In order to explain this phenomenon, the authors (all affiliated with the Department of Geological Sciences, U. of California) advance a hypothesis that suggests that the massive energy needed for these changes came for the release of "frozen" methane hydrates (clathrates) stored in marine sediments on continental margins. They argue that the release of the methane caused feedback processes that would explain the surprisingly rapid changes. Annotation copyrighted by Book News, Inc., Portland, OR.

Book Synopsis Climate Stabilization Targets by : National Research Council
Download or read book Climate Stabilization Targets written by National Research Council and published by National Academies Press. This book was released on 2011-02-11 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch where human activities will largely determine the evolution of Earth's climate. Because carbon dioxide in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe. Emissions reductions decisions made today matter in determining impacts experienced not just over the next few decades, but in the coming centuries and millennia. According to Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia, important policy decisions can be informed by recent advances in climate science that quantify the relationships between increases in carbon dioxide and global warming, related climate changes, and resulting impacts, such as changes in streamflow, wildfires, crop productivity, extreme hot summers, and sea level rise. One way to inform these choices is to consider the projected climate changes and impacts that would occur if greenhouse gases in the atmosphere were stabilized at a particular concentration level. The book quantifies the outcomes of different stabilization targets for greenhouse gas concentrations using analyses and information drawn from the scientific literature. Although it does not recommend or justify any particular stabilization target, it does provide important scientific insights about the relationships among emissions, greenhouse gas concentrations, temperatures, and impacts. Climate Stabilization Targets emphasizes the importance of 21st century choices regarding long-term climate stabilization. It is a useful resource for scientists, educators and policy makers, among others.
Book Synopsis Realizing the Energy Potential of Methane Hydrate for the United States by : National Research Council
Download or read book Realizing the Energy Potential of Methane Hydrate for the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-30 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural gas, composed mostly of methane, is the cleanest of all the fossil fuels, emitting 25-50% less carbon dioxide than either oil or coal for each unit of energy produced. In recent years, natural gas supplied approximately 20-25% of all energy consumed in the United States. Methane hydrate is a potentially enormous and as yet untapped source of methane. The Department of Energy's Methane Hydrate Research and Development Program has been tasked since 2000 to implement and coordinate a national methane hydrate research effort to stimulate the development of knowledge and technology necessary for commercial production of methane from methane hydrate in a safe and environmentally responsible way. Realizing the Energy Potential of Methane Hydrate for the United States evaluates the program's research projects and management processes since its congressional re-authorization in 2005, and presents recommendations for its future research and development initiatives.
Book Synopsis Scientific Application of Baseline Observations of Atmospheric Composition (SABOAC) by : Dieter H. Ehhalt
Download or read book Scientific Application of Baseline Observations of Atmospheric Composition (SABOAC) written by Dieter H. Ehhalt and published by Springer Science & Business Media. This book was released on 1987 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Southern Hemisphere commands an increasing interest among atmospheric chemists. It has smaller and less industrialized continents than the Northern Hemisphere and thus enjoys lower emissions of anthropogenic and biogenic pollu tants. As a consequence, the concentrations of trace species are lower in the Sou thern Hemisphere, giving rise to significant inter-hemispheric gradients. From an observation of the climatology of the various trace gas gradients important conclu sions on the chemical lifetimes, the distribution of sources and transport of trace species can be derived. Thus it is only fitting that the CSIRO Division of Atmos pheric Research, Aspendale, Australia, hosted the Conference on the Scientific Application of Baseline Observations of Atmospheric Composition (SABOAC). It was convened by Dr Graeme Pearman of the CSIRO and sponsored by the CSIRO and the Australian Bureau of Meteorology. Graeme Pearman and Ian Galbally of the CSIRO also agreed to serve as Guest Editors. The Conference was well attended and because of its location enjoyed an un usually large number of participants from the Southern Hemisphere. About 40 papers were presented with a large share of original contributions. At this point we would like to thank the reviewers who helped to maintain strict standards. The con ference topics ranged from Nonreactive Gases, Reactive Gases, Transport, Parti culates, Precipitation Chemistry, to Radiation and Carbondioxide. The present Proceedings do not quite maintain that sequence but partly reflect the order of receipt. DIETER EHHALT 3 Journal of Atmospheric Chemistry 3 (l985), 3-27.
Book Synopsis Verifying Greenhouse Gas Emissions by : National Research Council
Download or read book Verifying Greenhouse Gas Emissions written by National Research Council and published by National Academies Press. This book was released on 2010-07-28 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's nations are moving toward agreements that will bind us together in an effort to limit future greenhouse gas emissions. With such agreements will come the need for all nations to make accurate estimates of greenhouse gas emissions and to monitor changes over time. In this context, the present book focuses on the greenhouse gases that result from human activities, have long lifetimes in the atmosphere and thus will change global climate for decades to millennia or more, and are currently included in international agreements. The book devotes considerably more space to CO2 than to the other gases because CO2 is the largest single contributor to global climate change and is thus the focus of many mitigation efforts. Only data in the public domain were considered because public access and transparency are necessary to build trust in a climate treaty. The book concludes that each country could estimate fossil-fuel CO2 emissions accurately enough to support monitoring of a climate treaty. However, current methods are not sufficiently accurate to check these self-reported estimates against independent data or to estimate other greenhouse gas emissions. Strategic investments would, within 5 years, improve reporting of emissions by countries and yield a useful capability for independent verification of greenhouse gas emissions reported by countries.
