Available in PDF, EPUB and Kindle. Book excerpt: In 2001 a panel representing virtually all the world's governments and climate scientists announced that they had reached a consensus: the world was warming at a rate without precedent during at least the last ten millennia, and that warming was caused by the buildup of greenhouse gases from human activity. The consensus itself was at least a century in the making. The story of how scientists reached their conclusion--by way of unexpected twists and turns and in the face of formidable intellectual, financial, and political obstacles--is told for the first time in The Discovery of Global Warming. Spencer R. Weart lucidly explains the emerging science, introduces us to the major players, and shows us how the Earth's irreducibly complicated climate system was mirrored by the global scientific community that studied it. Unlike familiar tales of Science Triumphant, this book portrays scientists working on bits and pieces of a topic so complex that they could never achieve full certainty--yet so important to human survival that provisional answers were essential. Weart unsparingly depicts the conflicts and mistakes, and how they sometimes led to fruitful results. His book reminds us that scientists do not work in isolation, but interact in crucial ways with the political system and with the general public. The book not only reveals the history of global warming, but also analyzes the nature of modern scientific work as it confronts the most difficult questions about the Earth's future. Table of Contents: Preface 1. How Could Climate Change? 2. Discovering a Possibility 3. A Delicate System 4. A Visible Threat 5. Public Warnings 6. The Erratic Beast 7. Breaking into Politics 8. The Discovery Confirmed Reflections Milestones Notes Further Reading Index Reviews of this book: A soberly written synthesis of science and politics. --Gilbert Taylor, Booklist Reviews of this book: Charting the evolution and confirmation of the theory [of global warming], Spencer R. Weart, director of the Center for the History of Physics of the American Institute of Physics, dissects the interwoven threads of research and reveals the political and societal subtexts that colored scientists' views and the public reception their work received. --Andrew C. Revkin, New York Times Book Review Reviews of this book: It took a century for scientists to agree that gases produced by human activity were causing the world to warm up. Now, in an engaging book that reads like a detective story, physicist Weart reports the history of global warming theory, including the internal conflicts plaguing the research community and the role government has had in promoting climate studies. --Publishers Weekly Reviews of this book: It is almost two centuries since the French mathematician Jean Baptiste Fourier discovered that the Earth was far warmer than it had any right to be, given its distance from the Sun...Spencer Weart's book about how Fourier's initially inconsequential discovery finally triggered urgent debate about the future habitability of the Earth is lucid, painstaking and commendably brief, packing everything into 200 pages. --Fred Pearce, The Independent Reviews of this book: [The Discovery of Global Warming] is a well-written, well-researched and well-balanced account of the issues involved...This is not a sermon for the faithful, or verses from Revelation for the evangelicals, but a serious summary for those who like reasoned argument. Read it--and be converted. --John Emsley, Times Literary Supplement Reviews of this book: This is a terrific book...Perhaps the finest compliment I could give this book is to report that I intend to use it instead of my own book...for my climate class. The Discovery of Global Warming is more up-to-date, better balanced historically, beautifully written and, not least important, short and to the point. I think the [Intergovernmental Panel on Climate Change] needs to enlist a few good historians like Weart for its next assessment. --Stephen H. Schneider, Nature Reviews of this book: This short, well-written book by a science historian at the American Institute of Physics adds a serious voice to the overheated debate about global warming and would serve as a great starting point for anyone who wants to better understand the issue. --Maureen Christie, American Scientist Reviews of this book: I was very pleasantly surprised to find that Spencer Weart's account provides much valuable and interesting material about how the discipline developed--not just from the perspective of climate science but also within the context of the field's relation to other scientific disciplines, the media, political trends, and even 20th-century history (particularly the Cold War). In addition, Weart has done a valuable service by recording for posterity background information on some of the key discoveries and historical figures who contributed to our present understanding of the global warming problem. --Thomas J. Crowley, Science Reviews of this book: Weart has done us all a service by bringing the discovery of global warming into a short, compendious and persuasive book for a general readership. He is especially strong on the early days and the scientific background. --Crispin Tickell, Times Higher Education Supplement A Capricious Beast Ever since the days when he had trudged around fossil lake basins in Nevada for his doctoral thesis, Wally Broecker had been interested in sudden climate shifts. The reported sudden jumps of CO2 in Greenland ice cores stimulated him to put this interest into conjunction with his oceanographic interests. The result was a surprising and important calculation. The key was what Broecker later described as a "great conveyor belt'"of seawater carrying heat northward. . . . The energy carried to the neighborhood of Iceland was "staggering," Broecker realized, nearly a third as much as the Sun sheds upon the entire North Atlantic. If something were to shut down the conveyor, climate would change across much of the Northern Hemisphere' There was reason to believe a shutdown could happen swiftly. In many regions the consequences for climate would be spectacular. Broecker was foremost in taking this disagreeable news to the public. In 1987 he wrote that we had been treating the greenhouse effect as a 'cocktail hour curiosity,' but now 'we must view it as a threat to human beings and wildlife.' The climate system was a capricious beast, he said, and we were poking it with a sharp stick. I found the book enjoyable, thoughtful, and an excellent introduction to the history of what may be one of the most important subjects of the next one hundred years. --Clark Miller, University of Wisconsin The Discovery of Global Warming raises important scientific issues and topics and includes essential detail. Readers should be able to follow the discussion and emerge at the end with a good understanding of how scientists have developed a consensus on global warming, what it is, and what issues now face human society. --Thomas R. Dunlap, Texas A&M University

Available in PDF, EPUB and Kindle. Book excerpt: Analysis of climate change policy innovations across North America at transnational, federal, state, and local levels, involving public, private, and civic actors. North American policy responses to global climate change are complex and sometimes contradictory and reach across multiple levels of government. For example, the U.S. federal government rejected the Kyoto Protocol and mandatory greenhouse gas (GHG) restrictions, but California developed some of the world's most comprehensive climate change law and regulation; Canada's federal government ratified the Kyoto Protocol, but Canadian GHG emissions increased even faster than those of the United States; and Mexico's state-owned oil company addressed climate change issues in the 1990s, in stark contrast to leading U.S. and Canadian energy firms. This book is the first to examine and compare political action for climate change across North America, at levels ranging from continental to municipal, in locations ranging from Mexico to Toronto to Portland, Maine. Changing Climates in North American Politics investigates new or emerging institutions, policies, and practices in North American climate governance; the roles played by public, private, and civil society actors; the diffusion of policy across different jurisdictions; and the effectiveness of multilevel North American climate change governance. It finds that although national climate policies vary widely, the complexities and divergences are even greater at the subnational level. Policy initiatives are developed separately in states, provinces, cities, large corporations, NAFTA bodies, universities, NGOs, and private firms, and this lack of coordination limits the effectiveness of multilevel climate change governance. In North America, unlike much of Europe, climate change governance has been largely bottom-up rather than top-down.

Book excerpt: The International Year of Planet Earth (IYPE) was established as a means of raising worldwide public and political awareness of the vast, though frequently under-used, potential the Earth Sciences possess for improving the quality of life of the peoples of the world and safeguarding Earth’s rich and diverse environments. The International Year project was jointly initiated in 2000 by the International Union of Geological Sciences (IUGS) and the Earth Science Division of the United Nations Educational, Scienti?c and Cultural Organisation (UNESCO). IUGS, which is a Non-Governmental Organisation, and UNESCO, an Inter-Governmental Organisation, already shared a long record of productive cooperation in the na- ral sciences and their application to societal problems, including the International Geoscience Programme (IGCP) now in its fourth decade. With its main goals of raising public awareness of, and enhancing research in the Earth sciences on a global scale in both the developed and less-developed countries of the world, two operational programmes were demanded. In 2002 and 2003, the Series Editors together with Dr. Ted Nield and Dr. Henk Schalke (all four being core members of the Management Team at that time) drew up outlines of a Science and an Outreach Programme. In 2005, following the UN proclamation of 2008 as the United Nations International Year of Planet Earth, the “Year” grew into a triennium (2007–2009).

Book excerpt: This study examines how the idea of having to adapt to a changing climate influences recent Rwandan environmental politics and the relations with international organizations and NGOs. By conceptualizing adaptation as matter of translation, processes of resignification and network building are highlighted, taking broader social developments, historical trajectories and the makeup of Rwandan international relations into consideration. Based on analyses of a variety of primary and secondary data, the main findings add to a more detailed understanding of rationalizing, planning, and implementing climate change adaptation.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change is a critical issue for heritage studies. Sites, objects and ways of life all are coming under threat, requiring alternative management, or requiring specific climate change adaptation. Heritage is key to interpreting the societal significance of climate change; notions (and images) of the past are crucial to our understanding of the present, and are used to prompt actions that help society define and achieve a specific and desired future. Relatively little attention has been paid to the critical intersections between heritage and climate change. The Future of Heritage as Climates Change frames the intellectual context within which heritage and climate change can be examined, presenting cases and sub-fields in which the heritage-climate change nexus is being examined and provides synthetic analyses through five overarching themes: The heritage of change among coastal communities: liminality and the politics of engagement Dwelling materials: processes and possibilities; Environmental heritage: meanings of the past – prospects for the future; Blurring the boundaries of nature and culture: the politics of anticipation; Climate change and heritage practice: adaptation and resilience. The Future of Heritage as Climates Change provides scholars, managers, policy makers and students with a much needed examination of heritage and climate change to help make critical decisions in the next several decades.

Book excerpt: Many of us have concerns about the effects of climate change on Earth, but we often overlook the essential issue of human health. This book addresses that oversight and enlightens readers about the most important aspect of one of the greatest challenges of our time. The global environment is under massive stress from centuries of human industrialization. The projections regarding climate change for the next century and beyond are grim. The impact this will have on human health is tremendous, and we are only just now discovering what the long-term outcomes may be. By weighing in from a physician’s perspective, Jay Lemery and Paul Auerbach clarify the science, dispel the myths, and help readers understand the threats of climate change to human health. No better argument exists for persuading people to care about climate change than a close look at its impacts on our physical and emotional well-being. The need has never been greater for a grounded, informative, and accessible discussion about this topic. In this groundbreaking book, the authors not only sound the alarm but address the health issues likely to arise in the coming years.

Available in PDF, EPUB and Kindle. Book excerpt: The climate record for the past 100,000 years clearly indicates that the climate system has undergone periodic-and often extreme-shifts, sometimes in as little as a decade or less. The causes of abrupt climate changes have not been clearly established, but the triggering of events is likely to be the result of multiple natural processes. Abrupt climate changes of the magnitude seen in the past would have far-reaching implications for human society and ecosystems, including major impacts on energy consumption and water supply demands. Could such a change happen again? Are human activities exacerbating the likelihood of abrupt climate change? What are the potential societal consequences of such a change? Abrupt Climate Change: Inevitable Surprises looks at the current scientific evidence and theoretical understanding to describe what is currently known about abrupt climate change, including patterns and magnitudes, mechanisms, and probability of occurrence. It identifies critical knowledge gaps concerning the potential for future abrupt changes, including those aspects of change most important to society and economies, and outlines a research strategy to close those gaps. Based on the best and most current research available, this book surveys the history of climate change and makes a series of specific recommendations for the future.

This book was released on 2018-06-18 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
