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.
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.

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).

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.
Download or read book Methane and Climate Change written by Peter Smith and published by Earthscan. This book was released on 2010 with total page 273 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."--Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: While a number of gases are implicated in global warming, carbon dioxide is the most important contributor, and in one sense the entire phenomena can be seen as a human-induced perturbation of the carbon cycle. The Global Carbon Cycle offers a scientific assessment of the state of current knowledge of the carbon cycle by the world's leading scientists sponsored by SCOPE and the Global Carbon Project, and other international partners. It gives an introductory over-view of the carbon cycle, with multidisciplinary contributions covering biological, physical, and social science aspects. Included are 29 chapters covering topics including: an assessment of carbon-climate-human interactions; a portfolio of carbon management options; spatial and temporal distribution of sources and sinks of carbon dioxide; socio-economic driving forces of emissions scenarios. Throughout, contributors emphasize that all parts of the carbon cycle are interrelated, and only by developing a framework that considers the full set of feedbacks will we be able to achieve a thorough understanding and develop effective management strategies. The Global Carbon Cycle edited by Christopher B. Field and Michael R. Raupach is part of the Rapid Assessment Publication series produced by the Scientific Committee on Problems of the Environment (SCOPE), in an effort to quickly disseminate the collective knowledge of the world's leading experts on topics of pressing environmental concern.
Download or read book The Changing Atmosphere written by F. S. Rowland and published by . This book was released on 1988-12-12 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Changing Atmosphere F. S. Rowland I. S. A. Isaksen Editors The global distribution of a large number of trace gases and aerosol particles is changing. Many of these species are of importance for the Earth’s climate and the oxidation capacity of the atmosphere. Changes may therefore be important in the future for a wide range of environmental problems such as global temperature changes, the oxidation of acidic species, formation of photochemical oxidants, and depletion of the stratospheric ozone layer. In this volume four specific areas directly related to these problems are discussed: (a) how the atmosphere has already changed, (b) the oxidizing capacity of the atmosphere, (c) changes in the Antarctic ozone, and (d) trace substances and radiation balance of the Earth. The authors of the background papers and the group reports discuss the state of knowledge in these four areas, with special emphasis on possible changes that have occurred in the global distribution of trace gases and aerosol particles as a result of human activities. This volume should appeal, in particular, to scientists working in the fields of atmospheric chemistry and physics, meteorology, and those interested in environmental issues such as climate change, ozone depletion, and tropospheric pollution.

Download or read book Greenhouse Gases Sources Sinks and Mitigation written by Saurabh Sonwani and published by Springer Nature. This book was released on 2022-01-21 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book begins with a brief background on greenhouse gases sources and sinks and continues with a discussion in different sectors including forest fluxes to human health and modeling techniques to policy measures. The chapters explore in detail about the GHG emission budgets, mitigation strategies, technical advancement and input-output analysis. Greenhouse gases (GHGs) occur naturally in our atmosphere and are essential to the survival of most of the organisms on the planet earth. GHGs such as such as carbon dioxide, methane, nitrous oxide, and ozone etc. play a major role in balancing the radiative budget, by absorbing or emitting some of the infrared rays reflecting from the earth’s surface. But unfortunately, anthropogenic activities like use of fossil fuel, intensive agriculture and livestock farming, use of synthetic fertilizers, deforestation, and industrial processes etc. have drastically interfered in the natural air composition, by releasing excess greenhouse gases into the atmosphere. This has led to the increase in the ability of the atmosphere to absorb more infrared energy. This book is a complete information set covering all aspects of GHGs, sources, sinks and control/mitigation strategies. This book is also written in simple language with helpful photographs, diagrams and flowcharts which will make the reader comfortable in understanding the concepts a more relatively easier way. The book is a valuable tool for students in Environmental Science, Ecology, Biological Science, Economics and Agriculture. It is unique to environmental consultants, researchers and other professionals involved in climate change studies, Non-governmental organizations (NGO’s).

This book was released on 2005-07-20 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. PURPOSE OF PRESENT BOOK During the period May 19-26, 2003 the NATO Advanced Research Workshop (ARW) “Mud volcanism, Geodynamics and Seismicity” was held in Baku. Participants coming from USA, Germany, France, Italy, Portugal, Russian Federation, Ukraine, Romania, Georgia, UK, Israel, Azerbaijan, Tunisia have discussed about different geodynamic features of mud volcanism and participated to field trips oriented to a better knowledge of mud volcanic features. The Meeting focused on many features of mud volcanism occurrence and related geodynamic topics. The purpose of present book is to collect contributions discussed during the Meeting and to fill a marked editorial gap on mud volcanism. Mud volcanism was to date described by local monographies or by articles published by scientific journals. In particular no books were published on topics able to highlight the link among mud volcanism, geodynamics and seismicity. Mud volcano of Nirano (Northern Italy). Engraving from Stoppani A. (1871), Corso di Geologia, Milan, Bernardoni G. and Brigola G. Publishers. 2. WHY MUD VOLCANOES ARE GEOLOGICALLY IMPORTANT ? Mud volcanoes have attracted the attention of earth scientists for many years. Due to their importance in hydrocarbon research, a consistent progress in the knowledge of mud volcanism took place in the past twenty years. Mud extrusion is a well-known phenomenon occurring in geological environments where fluid-rich, fine grained sediments ascend within a lithologic succession due to their buoyancy.
Download or read book Plows Plagues and Petroleum written by William F. Ruddiman and published by Princeton University Press. This book was released on 2010-03-22 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.

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.
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.
