This is one of two volumes that provide more detailed scientific and technical information on global environmental problems than could adequately be summarized in the Report of the Study of Critical Environmental Problems (SCEP), Man's Impact on the Global Environment (MIT Press, 1970). SCEP presents the results of a one-month, interdisciplinary examination of the global climatic and ecological effects of man's activities which was sponsored by the Massachusetts Institute of Technology and conducted during the month of July 1970 at Williams College, Williamstown, Massachusetts. This and the companion volume, Man's Impact on Terrestrial and Oceanic Ecosystems,reproduce, supplement, and complement material found in the SCEP report and will serve as useful reference works for researchers and students in the many disciplines involved in solving the serious problems of environmental pollution. Theories and speculations about the effects of environmental pollution warn of both imminent and potential global catastrophes from—among other things—the build up of CO 2 from fossil-fuel combustion, the accumulation of DDT in both animals and humans, and the systematic release of such toxic materials as heavy metals, oil, and radioactive substances. Man's Impact on the Climateprovides a much-needed overview of the present state of knowledge about the climate, the atmospheric processes that produce climate and climate change and the interaction of pollutants with these processes; the modeling and monitoring tools that are available for learning more about these areas; and actions that might be taken to ameliorate problems that are understood. The book contains forty-eight chapters of varying length, scope, depth, complexity, and style—compiled from background materials prepared for SCEP, working papers written during the Study, and a few selected articles that have been previously published. SCEP Work Group reports that deal with climate and with atmospheric monitoring and the summary of those reports are reproduced in Part I. Part II provides a broad semitechnical view of the factors involved in determining climate and in changing climate and outlines the ways in which man might affect these processes by introducing pollutants into the environment. Mathematical modeling and monitoring techniques that are necessary to understand the factors influencing climate conditions are introduced in Parts III and IV, respectively. The next five sections discuss specific pollutants and their effects on the climate: Carbon Dioxide and Atmospheric Heating, Particles and Turbidity, Particles and Clouds, Contaminants of the Upper Atmosphere, and A Nonproblem and a Potential Problem (oxygen depletion and clearing of the Amazon forest). Each section treats the theoretical and empirical evidence available on predicted or observed effects and indicates the monitoring and measurement methods that can be used to increase knowledge in these areas and/or alert man to his impact on the climate. Monitoring techniques that are applicable to most of these problems are covered in detail in Part X. "More research" is not the simple answer to environmental issues. A final section of the book illustrates some of the complex social, political, and technical issues that the scientists and his fellow citizens must confront together if decisions that could avert potential disasters are ever to be made and implemented.
“An excellent volume with mature, sophisticated, comprehensive research by leaders in the fields of archaeology, zooarchaeology, and paleoarchaeology that will be useful to scientists of many interests.”—David Steadman, author of Extinction and Biogeography of Tropical Pacific Birds “This volume will make a significant contribution to our understanding of ancient human impacts on marine ecosystems, which will be of interest to all researchers who are concerned about the environment. The editors and contributors are commended for their efforts on this significant research topic.”—Steven R. James, coeditor of The Archaeology of Global Change: The Impact of Humans on Their Environment
We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet presents prioritized science, applications, and observations, along with related strategic and programmatic guidance, to support the U.S. civil space Earth observation program over the coming decade.
Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.
Natural and human-induced changes in Earth's interior, land surface, biosphere, atmosphere, and oceans affect all aspects of life. Understanding these changes requires a range of observations acquired from land-, sea-, air-, and space-based platforms. To assist NASA, NOAA, and USGS in developing these tools, the NRC was asked to carry out a "decadal strategy" survey of Earth science and applications from space that would develop the key scientific questions on which to focus Earth and environmental observations in the period 2005-2015 and beyond, and present a prioritized list of space programs, missions, and supporting activities to address these questions. This report presents a vision for the Earth science program; an analysis of the existing Earth Observing System and recommendations to help restore its capabilities; an assessment of and recommendations for new observations and missions for the next decade; an examination of and recommendations for effective application of those observations; and an analysis of how best to sustain that observation and applications system.
This book offers an up-to-date review of our current understanding of climate change in the North Sea and adjacent areas, as well as its impact on ecosystems and socio-economic sectors. It provides a detailed assessment of climate change based on published scientific work compiled by independent international experts from climate-related disciplines such as oceanography, atmospheric sciences, marine and terrestrial ecology, using a regional evaluation and review process similar to that of the Intergovernmental Panel on Climate Change (IPCC). It provides a comprehensive overview of all aspects of our changing climate, discussing a wide range of topics including past, current and future climate change, and climate-related changes in marine, terrestrial and freshwater ecosystems. It also explores the impact of climate change on socio-economic sectors such as fisheries, agriculture, coastal zone management, coastal protection, urban climate, recreation/tourism, offshore activities/energy, and air pollution.
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.
​This book is an update of the first BACC assessment, published in 2008. It offers new and updated scientific findings in regional climate research for the Baltic Sea basin. These include climate changes since the last glaciation (approx. 12,000 years ago), changes in the recent past (the last 200 years), climate projections up until 2100 using state-of-the-art regional climate models and an assessment of climate-change impacts on terrestrial, freshwater and marine ecosystems. There are dedicated new chapters on sea-level rise, coastal erosion and impacts on urban areas. A new set of chapters deals with possible causes of regional climate change along with the global effects of increased greenhouse gas concentrations, namely atmospheric aerosols and land-cover change. The evidence collected and presented in this book shows that the regional climate has already started to change and this is expected to continue. Projections of potential future climates show that the region will probably become considerably warmer and wetter in some parts, but dryer in others. Terrestrial and aquatic ecosystems have already shown adjustments to increased temperatures and are expected to undergo further changes in the near future. The BACC II Author Team consists of 141 scientists from 12 countries, covering various disciplines related to climate research and related impacts. BACC II is a project of the Baltic Earth research network and contributes to the World Climate Research Programme.
