Acid rain has changed the face of the Adirondacks, created political tensions between the Northeast and the Midwest, and served as both a harbinger of global climate change and a "fire drill" for public- and private-sector responses to environmental crises. The history of acid rain research is a striking case in which a large-scale and long-term environmental problem was addressed in part through scientifically motivated changes in public policy. In the 1970s, acid rain was viewed as a simple problem that was limited in scope and characterized by "dead," fishless lakes. Scientists now have broader insights into the processes by which acid rain sets off a cascade of adverse effects in ecosystems as its components move through air, soil, vegetation, and surface waters. Written and designed to appeal to both scientists and lay readers, this book is a landmark example of scientific communication that provides a comprehensive scientific history of the phenomenon, from its discovery to the full understanding of the scope of its effects and the ultimate responses that have mitigated some of the damage to the region's lakes and forests. This book is published in association with the Adirondack Lakes Survey Corporation with the support of the Wildlife Conservation Society, United States Environmental Protection Agency, New York State Department of Environmental Conservation, and New York State Energy Research and Development Authority.
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.
Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.
Presents an overview of the normal functioning of terrestrial ecosystems and up-to-date documentation on the effects of acid precipitation.
This book provides a unique overview of research methods over the past 25 years assessing critical loads and temporal effects of the deposition of air pollutants. It includes critical load methods and applications addressing acidification, eutrophication and heavy metal pollution of terrestrial and aquatic ecosystems. Applications include examples for each air pollution threat, both at local and regional scale, including Europe, Asia, Canada and the US. The book starts with background information on the effects of the deposition of sulphur, nitrogen and heavy metals and geochemical and biological indicators for risk assessments. The use of those indicators is then illustrated in the assessment of critical loads and their exceedances and in the temporal assessment of air pollution risks. It also includes the most recent developments of assessing critical loads and current and future risks of soil and water chemistry and biodiversity under climate change, with a special focus on nitrogen. The book thus provides a complete overview of the knowledge that is currently used for the scientific support of policies in the field of air pollution control to protect ecosystem services.
