Available in PDF, EPUB and Kindle. Book excerpt: #1 NEW YORK TIMES BEST SELLER • In this urgent, authoritative book, Bill Gates sets out a wide-ranging, practical—and accessible—plan for how the world can get to zero greenhouse gas emissions in time to avoid a climate catastrophe. Bill Gates has spent a decade investigating the causes and effects of climate change. With the help of experts in the fields of physics, chemistry, biology, engineering, political science, and finance, he has focused on what must be done in order to stop the planet's slide to certain environmental disaster. In this book, he not only explains why we need to work toward net-zero emissions of greenhouse gases, but also details what we need to do to achieve this profoundly important goal. He gives us a clear-eyed description of the challenges we face. Drawing on his understanding of innovation and what it takes to get new ideas into the market, he describes the areas in which technology is already helping to reduce emissions, where and how the current technology can be made to function more effectively, where breakthrough technologies are needed, and who is working on these essential innovations. Finally, he lays out a concrete, practical plan for achieving the goal of zero emissions—suggesting not only policies that governments should adopt, but what we as individuals can do to keep our government, our employers, and ourselves accountable in this crucial enterprise. As Bill Gates makes clear, achieving zero emissions will not be simple or easy to do, but if we follow the plan he sets out here, it is a goal firmly within our reach.

Download or read book Ozone Discourses written by Karen Litfin and published by Columbia University Press. This book was released on 1994 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can scientific knowledge be translated into political change? Ozone Discourse examines the first global environment treaty, the Montreal Protocol and its subsequent revisions, which was a highly effective collaboration among scientists, policymakers and activists. The treaties were the work of a small group of experts who, without conventional political or economic resources, were able to persuade most of the world's nations to agree to reduce and then eliminate chlorofluorocarbons. These experts used their understanding of atmospheric science to supplement the policymakers' short-term perspective with a wider, intergenerational timeframe characteristic of global environmental problems. Litfin argues that the discipline of international relations requires a broader conception of power in order to accomodate the knowledge-based problems such as environmental degradation.

Download or read book Protecting the Ozone Layer written by Stephen O Andersen and published by Routledge. This book was released on 2012-05-23 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970s the world became aware of a huge danger: the destruction of the stratospheric ozone layer by CFCs escaping into the atmosphere, and the damage this could do to human health and the food chain. So great was the threat that by 1987 the UN had succeeded in coordinating an international treaty to phase out emissions; which, over the following 15 years has been implemented. It has been hailed as an outstanding success. It needed the participation of all the parties: governments, industry, scientists, campaigners, NGOs and the media, and is a model for future treaties. This volume provides the authoritative and comprehensive history of the whole process from the earliest warning signs to the present. It is an invaluable record for all those involved and a necessary reference for future negotiations to a wide range of scholars, students and professionals.

Download or read book Climate Variability and Sunspot Activity written by Indrani Roy and published by Springer. This book was released on 2018-06-25 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book promotes a better understanding of the role of the sun on natural climate variability. It is a comprehensive reference book that appeals to an academic audience at the graduate, post-graduate and PhD level and can be used for lectures in climatology, environmental studies and geography. This work is the collection of lecture notes as well as synthesized analyses of published papers on the described subjects. It comprises 18 chapters and is divided into three parts: Part I discusses general circulation, climate variability, stratosphere-troposphere coupling and various teleconnections. Part II mainly explores the area of different solar influences on climate. It also discusses various oceanic features and describes ocean-atmosphere coupling. But, without prior knowledge of other important influences on the earth’s climate, the understanding of the actual role of the sun remains incomplete. Hence, Part III covers burning issues such as greenhouse gas warming, volcanic influences, ozone depletion in the stratosphere, Arctic and Antarctic sea ice, etc. At the end of the book, there are few questions and exercises for students. This book is based on the lecture series that was delivered at the University of Oulu, Finland as part of M.Sc./ PhD module.

Download or read book Atoms Molecules and Light written by National Research Council and published by National Academies Press. This book was released on 2002-10-01 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the publication in 1994 of Atomic, Molecular, and Optical Science: An Investment in the Future (the FAMOS report), the National Research Council launched the series Physics in a New Era, its latest survey of physics. Each of the six area volumes in the survey focuses on a different subfield of physics, describing advances since the last decadal survey and suggesting future opportunities and directions. This survey culminated in 2001 with the publication of the seventh and final volume, Physics in a New Era: An Overview. Since the publication of the FAMOS report, the developments in atomic, molecular, and optical (AMO) science have been amazing. Significant advances in areas such as cooling and trapping, atom and quantum optics, single-atom and single-molecule detection, and ultrafast and ultra intense phenomena, along with the emergence of new applications, made it clear that an update of the FAMOS report was needed. With support from the National Science Foundation and the Department of Energy, the Committee for an Updated Assessment of Atomic, Molecular, and Optical Science was formed. The committee's statement of task reads as follows: The committee will prepare a narrative document that portrays the advances in AMO science and its impact on society. This report highlights selected forefront areas of AMO science, emphasizing recent accomplishments and new opportunities, identifies connections between AMO science and other scientific fields, emerging technologies, and national needs, describes career opportunities for AMO scientists. To accomplish its task and at the same time reach a broad audience, the committee decided to present its report in the form of a brochure highlighting selected advances, connections, and impacts on national needs. An exhaustive assessment of the field, which will fall within the purview of the next decadal survey, was not the goal of the update. The committee would like to express its gratitude for the informative interactions it had with many scientists and policy makers. Many colleagues completed a questionnaire and suggested topics to be included in this report. The final selection of topics was made in accordance with the criteria set forth in the statement of task. While this report was still being written, the tragic events of September 11, 2001, occurred. AMO science and its applications have already played and will continue to play a central role in our nation's response to terrorist threats from conventional as well as chemical or biological weapons. Some of the technology discussed in this report in the chapter "AMO Science Enhancing National Defense" was used successfully for the U.S. military response in Afghanistan-the Global Positioning System (GPS) and laser-guided munitions are just two examples. AMO science will also enable the development of early detection techniques that will help to neutralize the threat from biological and chemical agents.
