Greenhouse Gas Induced Climatic Change

Climate Change: Evidence and Causes is a jointly produced publication of The US National Academy of Sciences and The Royal Society. Written by a UK-US team of leading climate scientists and reviewed by climate scientists and others, the publication is intended as a brief, readable reference document for decision makers, policy makers, educators, and other individuals seeking authoritative information on the some of the questions that continue to be asked. Climate Change makes clear what is well-established and where understanding is still developing. It echoes and builds upon the long history of climate-related work from both national academies, as well as on the newest climate-change assessment from the United Nations' Intergovernmental Panel on Climate Change. It touches on current areas of active debate and ongoing research, such as the link between ocean heat content and the rate of warming.

The proceedings of this workshop provide a valuable review of the methodologies of climate observations during the past 150 years, together with a summary of their findings, and a description of the difficulties inherent in their interpretation. In addition the volume reviews the use of climate model simulations of greenhouse-gas-induced equilibrium and nonequilibrium change. Finally, the contributed papers consider the methodologies of climate change detection by comparison of model simulations and climate observations, a summary of findings, and a description of what should be done to detect GHG-induced climate change. The volume will be of particular interest to researchers and students in the fields of meteorology, atmospheric science, oceanography, global change and climate impact assessement. Scientists in related fields will find much of value also.

The warming of the Earth has been the subject of intense debate and concern for many scientists, policy-makers, and citizens for at least the past decade. Climate Change Science: An Analysis of Some Key Questions, a new report by a committee of the National Research Council, characterizes the global warming trend over the last 100 years, and examines what may be in store for the 21st century and the extent to which warming may be attributable to human activity.

It is the greatest environmental challenge of the 21st Century. But what do we truly know about global climate change? And what can we do about it? Most of the world's top scientists agree that emissions of carbon dioxide and other greenhouse gases from human activities such as industrial processes, fossil fuel combustion, and land-use changes are causing the earth to get warmer. Impacts of this warming may include damage to our coastal areas, accelerated rates of species loss, altered agricultural patterns, and increased incidences of infectious diseases. The effects of climate change - and efforts to mitigate climate change - could also have substantial economic ramifications. The book presents the latest research and analysis from prominent scientists, economists, academics, and policy-makers, including: "Tom Wigley" and "Joel Smith," who, along with other authors of the Science and Impacts chapter, explain the basic science of climate change, the growing evidence that human activities are changing our climate, and the impacts of these changes; "Eileen Claussen," "John Gummer," "Henry Lee," and other authors of the Global Strategies chapter, who describe what nations are or are not doing to address climate change, and the state of international climate talks; "Robert Stavins," "John Weyant," "Ev Ehrlich," and other economists, who explain why economic analyses of climate policy are conducted, why the projected costs of addressing climate change vary so widely among economic models, and how changes driven by today's economy can influence climate policy; "Gov. Jean Shaheen" and other authors of the Innovative Solutions chapter, who describe what state and local governments in theUnited States and multinational companies are doing to monitor and curb greenhouse gas emissions; and "Forest Reinhardt," who offers business leaders advice on steering their companies on a path that is healthy for business as well as the global climate.

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.

It is widely accepted in the scientific community that climate change is a reality, and that changes are happening with increasing rapidity. In this second edition, leading climate researcher Barrie Pittock revisits the effects that global warming is having on our planet, in light of ever-evolving scientific research. Presenting all sides of the arguments about the science and possible remedies, Pittock examines the latest analyses of climate change, such as new and alarming observations regarding Arctic sea ice, the recently published IPCC Fourth Assessment Report, and the policies of the new Australian Government and how they affect the implementation of climate change initiatives. New material focuses on massive investments in large-scale renewables, such as the kind being taken up in California, as well as many smaller-scale activities in individual homes and businesses which are being driven by both regulatory and market mechanisms. The book includes extensive endnotes with links to ongoing and updated information, as well as some new illustrations. While the message is clear that climate change is here (and in some areas, might already be having disastrous effects), there is still hope for the future, and the ideas presented here will inspire people to take action. Climate Change: The Science, Impacts and Solutions is an important reference for students in environmental or social sciences, policy makers, and people who are genuinely concerned about the future of our environment.

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.

At the recent UN Climate Change Conferences in Copenhagen, Cancun and Durban, the developed nations promised hundreds of billions of dollars in financial aid to help developing countries overcome global climate change dangers. The developed nations will need to spend many more billions to limit their own greenhouse gas pollution, the main cause of global warming and climate change. Will all this money and effort be wasted? This book argues that nearly all of the world's climate policy makers and expert advisors have been making tragic mistakes that ensure the failures of climate change mitigation attempts.The great majority of climate change programs, from American congressional bills to cap-and-trade economic incentive schemes to the Kyoto Protocol and other international treaties, rely on greenhouse gas emissions-reduction targets that will prove “too little, too late” by deferring strict pollution controls too far into the future. The inadequate emissions-reduction measures also will not be able to bridge the gap between the highest priorities of developed and developing nations. Vast discharges of greenhouse gases authorized by weak emissions-reduction programs in the next several decades virtually guarantee that the cumulative concentration of greenhouse gases in the atmosphere will keep increasing while climate change continues to grow worse.Rather than adopting ineffectual emissions-reduction programs that cannot limit the cumulative concentration of greenhouse gases in the air, this book proposes a shift to a “clean” technology-replacement strategy that could support current lifestyles and expanding economic development without further damaging our climate. The only way to reduce the greenhouse gas levels in the atmosphere enough to decrease climate change hazards is to replace large pollution sources as rapidly as feasible in as many industrial sectors and geographic regions as possible with “clean” alternative technologies, processes, and methods.
