CO2 Acidification in Aquatic Ecosystems: An Integrative Approach to Risk Assessment focuses on the characterization of different aspects of ecosystem science to describe the situation of CO2 acidification in aquatic ecosystems. This extensive coverage looks at the effects of CO2 acidification throughout all oceans and coastal areas. In addition, the book describes integrative approaches based on global case studies to determine the effects associated with this kind of acidification. It allows the reader to understand the different sources of CO2 in the aquatic ecosystems and the different approaches and lines of evidence available to characterize the impact of this acidification. This book provides researchers, professors and post graduate students in oceanography and aquatic ecology with a new and complete tool set to address and understand the potential impacts of CO2 acidification in aquatic ecosystems. Presents case studies and new data related to CO2 acidification in aquatic ecosystems Includes new approaches for understanding the behavior of organisms in aquatic ecosystems that are suffering stress from different sources of contamination at acidification conditions Provides an integrated approach to address the environmental quality in areas affected by acidification and contamination by other stressors

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.

Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

With increasing concentrations of carbon dioxide (CO2) in the atmosphere, the extent of effects on the ocean and marine resources is an increasing concern. One aspect of this issue is the ongoing process (known as ocean acidification) whereby seawater becomes less alkaline as more CO2 dissolves in it, causing hydrogen ion concentration in seawater to increase. Scientists are concerned that increasing hydrogen ion concentration could reduce growth or even cause the death of shell-forming animals (eg: corals, molluscs, and certain planktonic organisms) as well as disrupt marine food webs and the reproductive physiology of certain species. While not yet fully understood, the ecological and economic consequences of ocean acidification could be substantial. Scientists are concerned that increasing hydrogen ion concentration in seawater could alter biogeochemical cycles, disrupt physiological processes of marine organisms, and damage marine ecosystems. This book examines potential legislative action by Congress relating to authorising, funding, and co-ordinating research to increase knowledge about ocean acidification and its potential effects on marine ecosystems.

Over recent years, human activities such as the burning of fossil fuels have increased the amount of carbon dioxide gas emitted to the atmosphere--and the amount that dissolves into the ocean. Now, so much carbon dioxide has been absorbed by the ocean that the chemistry of seawater is changing, causing the ocean to become more acidic. Based on a National Research Council report, this booklet describes the well-understood chemistry of ocean acidification and explores the many questions that remain: How will ocean acidification impact marine life such as fish, corals, and shellfish? How will the effects on individual species scale up to whole ecosystems? What will ocean acidification mean for aquaculture, the fishing industry, and coastal tourism?

Global climate change affects productivity and species composition of freshwater and marine aquatic ecosystems by raising temperatures, ocean acidification, excessive solar UV and visible radiation. Effects on bacterioplankton and viruses, phytoplankton and macroalgae have farreaching consequences for primary consumers such as zooplankton, invertebrates and vertebrates, as well as on human consumption of fish, crustaceans and mollusks. It has affected the habitation of the Arctic and Antarctic oceans the most so far. Increasing pollution from terrestrial runoff, industrial, municipal and household wastes as well as marine transportation and plastic debris also affect aquatic ecosystems.
