Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes research and results that pertain to AFOSR agreement no. F49620-96-C-0024. The aim of this research program has been to improve prediction of aircraft contrail and cirrus cloud formation, and to improve understanding of their optical and physical properties. Toward this end, the investigators have used analysis of data from research aircraft, balloon-borne ice crystal replicator sondes, and radiosonde relative humidity measurements, as well as theoretical and numerical modeling techniques. The five categories of research covered in this report are: (1) Improving Vaisala RS80-A radiosonde relative humidity measurements; (2) Vertical distribution of cirrus microphysical and optical properties; (3) Relative humidity conditions for the formation of cirrus and contrails; (4) Variability of cirrus microphysical properties; and (5) Improved theory of contrail formation Research findings in each of these five categories resulted in at least one publication whose full or partial sponsorship by the AFOSR was acknowledged. The journal publications provide an in-depth discussion of the research conducted; this final report summarizes the findings.

Download or read book Escaping the Rabbit Hole written by West Mick and published by Simon and Schuster. This book was released on 2018-09-18 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth is flat, the World Trade Center collapse was a controlled demolition, planes are spraying poison to control the weather, and actors faked the Sandy Hook massacre…. All these claims are bunk: falsehoods, mistakes, and in some cases, outright lies. But many people passionately believe one or more of these conspiracy theories. They consume countless books and videos, join like-minded online communities, try to convert those around them, and even, on occasion, alienate their own friends and family. Why is this, and how can you help people, especially those closest to you, break free from the downward spiral of conspiracy thinking? In Escaping the Rabbit Hole, author Mick West shares over a decade’s worth of knowledge and experience investigating and debunking false conspiracy theories through his forum, MetaBunk.org, and sets forth a practical guide to helping friends and loved ones recognize these theories for what they really are. Perhaps counter-intuitively, the most successful approaches to helping individuals escape a rabbit hole aren’t comprised of simply explaining why they are wrong; rather, West’s tried-and-tested approach emphasizes clear communication based on mutual respect, honesty, openness, and patience. West puts his debunking techniques and best practices to the test with four of the most popular false conspiracy theories today (Chemtrails, 9/11 Controlled Demolition, False Flags, and Flat Earth) — providing road maps to help you to understand your friend and help them escape the rabbit hole. These are accompanied by real-life case studies of individuals who, with help, were able to break free from conspiracism. With sections on: the wide spectrum of conspiracy theories avoiding the “shill” label psychological factors and other complications (and concluding with) a look at the future of debunking Mick West has put forth a conclusive, well-researched, practical reference on why people fall down the conspiracy theory rabbit hole and how you can help them escape.

Available in PDF, EPUB and Kindle. Book excerpt: The growing problem of changing environmental conditions caused by climate destabilization is well recognized as one of the defining issues of our time. The root problem is greenhouse gas emissions, and the fundamental solution is curbing those emissions. Climate geoengineering has often been considered to be a "last-ditch" response to climate change, to be used only if climate change damage should produce extreme hardship. Although the likelihood of eventually needing to resort to these efforts grows with every year of inaction on emissions control, there is a lack of information on these ways of potentially intervening in the climate system. As one of a two-book report, this volume of Climate Intervention discusses albedo modification - changing the fraction of incoming solar radiation that reaches the surface. This approach would deliberately modify the energy budget of Earth to produce a cooling designed to compensate for some of the effects of warming associated with greenhouse gas increases. The prospect of large-scale albedo modification raises political and governance issues at national and global levels, as well as ethical concerns. Climate Intervention: Reflecting Sunlight to Cool Earth discusses some of the social, political, and legal issues surrounding these proposed techniques. It is far easier to modify Earth's albedo than to determine whether it should be done or what the consequences might be of such an action. One serious concern is that such an action could be unilaterally undertaken by a small nation or smaller entity for its own benefit without international sanction and regardless of international consequences. Transparency in discussing this subject is critical. In the spirit of that transparency, Climate Intervention: Reflecting Sunlight to Cool Earth was based on peer-reviewed literature and the judgments of the authoring committee; no new research was done as part of this study and all data and information used are from entirely open sources. By helping to bring light to this topic area, this book will help leaders to be far more knowledgeable about the consequences of albedo modification approaches before they face a decision whether or not to use them.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is a collection of papers presented at the 14th International Conference on Nucleation and Atmospheric Aerosols, Helsinki, 26 - 30 August 1996. The first conference of this series took place in Dublin (1955); second, Basel and Locarno (1956); third, Cambridge (1958); fourth, Frankfurt am Main and Heidelberg (1961); fifth, Clermont-Ferrand and Tolouse (1963); sixth, Albany and University Park (1966); seventh, Prague and Vienna (1969); eighth, Leningrad (1973); ninth, Galway (1977); tenth, Hamburg (1981); eleventh Budapest (1984); twelfth, Vienna (1988); thirteenth, Salt Lake City (1992). The Atmospheric Aerosol conference has been held jointly with the Nucleation Symposium since 1988 in Vienna in order to stimulate contacts between researchers in these closely related fields. The broad nature of the meeting and the scientific program resulted in 32 countries submitting papers for presentation. Covering both experimental and theoretical studies these papers are divided amongst the chapters on Nucleation, Stratospheric Aerosols and Ice Nucleation, Tropospheric Aerosols and Aerosol-Cloud-Climate Interaction. In addition to these contributed papers invitations to present a plenary lecture on topics of particular current interest were accepted by P.J. Crutzen, J. Gras, J.L. Katz, A.A. Lushnikov, D. Oxtoby, J.E. Penner, Th. Peter, F. Raes, S.E. Schwartz, R. Strey and G. Vali. These plenary papers together with the contributed papers provide a well-balanced perspective of the current research over the entire field and highlight some important issues.
Download or read book Aircraft Design for Reduced Climate Impact written by Emily Dallara and published by Stanford University. This book was released on 2011 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft affect global climate through emissions of greenhouse gases and their precursors and by altering cirrus cloudiness. Changes in operations and design of future aircraft may be necessary to meet goals for limiting climate change. One method for reducing climate impacts involves designing aircraft to fly at altitudes where the impacts of NOx emissions are less severe and persistent contrail formation is less likely. By considering these altitude effects and additionally applying climate mitigation technologies, impacts can be reduced by 45-70% with simultaneous savings in total operating costs. Uncertainty is assessed, demonstrating that relative climate impact savings can be expected despite large scientific uncertainties. Strategies for improving climate performance of existing aircraft are also explored, revealing potential climate impact savings of 20-40%, traded for a 2% increase in total operating costs and reduced maximum range.

Download or read book Human Environment Interactions written by Mark R. Welford and published by Springer Nature. This book was released on 2020-10-06 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook explores the growing area of human-environment interaction. We live in the Anthropocene, an era dominated by humans, but also by the positive yet destructive environmental feedbacks that are poised to completely reset the relationships between nature and society. Modern and historic political, social, and cultural processes and physical landscape responses determine the intensity of these impacts. Yet different cultural groups, political and economic entities view, react to, and impact these human-environmental processes in spatially distinct and divergent ways. Providing an accessible, up-to-date, approach to human-environment interactions with balanced coverage of both social and natural science approaches to core environmental issues, this textbook is an integrative, multi-disciplinary offering that discusses environmental issues and processes within the context of human societies. The book begins by addressing the three most pressing issues of our time: climate change, threshold exceedance, and the 6th mass extinction. From there the authors identify within chapters on resources, population, agriculture and urbanization what precipitated and continues to sustain these three issues. They end with a chapter outlining some practical solutions to our human-environment crises. The book will be a valuable resource for interdisciplinary environment related courses bridging the gap between the social and natural sciences, human geographies and physical geographies.
