| feedback loop definition environmental science: Policy Implications of Greenhouse Warming National Academy of Engineering, National Academy of Sciences, Policy and Global Affairs, Institute of Medicine, Committee on Science, Engineering, and Public Policy, Panel on Policy Implications of Greenhouse Warming, 1992-02-01 Global warming continues to gain importance on the international agenda and calls for action are heightening. Yet, there is still controversy over what must be done and what is needed to proceed. Policy Implications of Greenhouse Warming describes the information necessary to make decisions about global warming resulting from atmospheric releases of radiatively active trace gases. The conclusions and recommendations include some unexpected results. The distinguished authoring committee provides specific advice for U.S. policy and addresses the need for an international response to potential greenhouse warming. It offers a realistic view of gaps in the scientific understanding of greenhouse warming and how much effort and expense might be required to produce definitive answers. The book presents methods for assessing options to reduce emissions of greenhouse gases into the atmosphere, offset emissions, and assist humans and unmanaged systems of plants and animals to adjust to the consequences of global warming. |

| feedback loop definition environmental science: Earth System Science: A Very Short Introduction Tim Lenton, 2016-02-25 When humanity first glimpsed planet Earth from space, the unity of the system that supports humankind entered the popular consciousness. The concept of the Earth's atmosphere, biosphere, oceans, soil, and rocks operating as a closely interacting system has rapidly gained ground in science. This new field, involving geographers, geologists, biologists, oceanographers, and atmospheric physicists, is known as Earth System Science. In this Very Short Introduction, Tim Lenton considers how a world in which humans could evolve was created; how, as a species, we are now reshaping that world; and what a sustainable future for humanity within the Earth System might look like. Drawing on elements of geology, biology, chemistry, physics, and mathematics, Lenton asks whether Earth System Science can help guide us onto a sustainable course before we alter the Earth system to the point where we destroy ourselves and our current civilisation. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable. |

| feedback loop definition environmental science: Thinking in Systems Donella Meadows, 2008-12-03 The classic book on systems thinking—with more than half a million copies sold worldwide! This is a fabulous book... This book opened my mind and reshaped the way I think about investing.—Forbes Thinking in Systems is required reading for anyone hoping to run a successful company, community, or country. Learning how to think in systems is now part of change-agent literacy. And this is the best book of its kind.—Hunter Lovins In the years following her role as the lead author of the international bestseller, Limits to Growth—the first book to show the consequences of unchecked growth on a finite planet—Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Thinking in Systems is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life. Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking. While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner. In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions. |
| feedback loop definition environmental science: Paleoclimatology Gilles Ramstein, Amaëlle Landais, Nathaelle Bouttes, Pierre Sepulchre, Aline Govin, 2020-11-09 This two-volume book provides a comprehensive, detailed understanding of paleoclimatology beginning by describing the “proxy data” from which quantitative climate parameters are reconstructed and finally by developing a comprehensive Earth system model able to simulate past climates of the Earth. It compiles contributions from specialists in each field who each have an in-depth knowledge of their particular area of expertise. The first volume is devoted to “Finding, dating and interpreting the evidence”. It describes the different geo-chronological technical methods used in paleoclimatology. Different fields of geosciences such as: stratigraphy, magnetism, dendrochronology, sedimentology, are drawn from and proxy reconstructions from ice sheets, terrestrial (speleothems, lakes, and vegetation) and oceanic data, are used to reconstruct the ancient climates of the Earth. The second volume, entitled “Investigation into ancient climates,” focuses on building comprehensive models of past climate evolution. The chapters are based on understanding the processes driving the evolution of each component of the Earth system (atmosphere, ocean, ice). This volume provides both an analytical understanding of each component using a hierarchy of models (from conceptual to very sophisticated 3D general circulation models) and a synthetic approach incorporating all of these components to explore the evolution of the Earth as a global system. As a whole this book provides the reader with a complete view of data reconstruction and modeling of the climate of the Earth from deep time to present day with even an excursion to include impacts on future climate. |

| feedback loop definition environmental science: Closing the Feedback Loop Björn-Sören Gigler, Savita Bailur, 2014-05-22 Enhanced transparency, accountability, and government or donor responsiveness to people needs are imperative to achieve better and more sustainable development results on the ground. The rapid spread of new technologies is transforming the daily lives of millions of poor people around the world and has the potential to be a real game changer for development. Improved accountability and responsiveness are critical for reaching the goals of eliminating extreme poverty and promoting shared prosperity with a focus on improving the well-being of the most vulnerable and marginalized groups in society. Within the broader political economy context, many questions remain unanswered about the role that new technologies can play to act as an accelerator for closing the accountability gap. Within this context, this report brings together new evidence from leading academics and practitioners on the effects of technology-enabled citizen engagement. The report aims to address the following four main questions: how do new technologies empower communities through participation, transparency, and accountability?; are technologies an accelerator for closing the accountability gap - the space between supply (governments, service providers) and demand (citizens, communities,civil society organizations) that must be bridged for open and collaborative governance?; under what conditions does this occur?; and what are the experiences and lessons learned from existing grassroots innovators and donor-supported citizen engagement and crowdsourcing programs, and how can these programs be replicated or scaled up?. The report presents a theoretical framework about the linkages between new technologies, participation, empowerment, and the improvement of poor people's human well-being based on Amartya Sen's capability approach. The book provides rich case studies about the different factors that influence whether or not information and communication technology (ICT)-enabled citizen engagement programs can improve the delivery and quality of public services to poor communities. The report analyzes in depth both the factors and process of using new technologies to enhance the delivery of primary health services to pregnant women in Karnataka, India, and of several community mapping and crowdsourcing programs in Guinea, Haiti, Kenya, Libya, Sudan, and other countries. |
| feedback loop definition environmental science: Clouds and Climate A. Pier Siebesma, Sandrine Bony, Christian Jakob, Bjorn Stevens, 2020 Clouds have always fascinated humans, but never has the need to understand them been so vital. As global surface temperature increases, human activities influence particulate matter in the atmosphere, and the properties of the land surface, clouds are expected to change, with manifold consequences for the climate. Clouds influence climate through their regulation of radiant energy transfer, through their role in convective energy transport, and in mediating the water cycle. Cloud research has never been so exciting. It is a topic with many new opportunities. New satellite observations from space with active instruments such as lidar and radar allow for the first time to reconstruct the three-dimensional distribution of clouds across Earth. Likewise, numerical simulations are beginning to globally resolve the three spatial dimensions of clouds as well as their dynamic evolution. This is enabling researchers, for the first time, to link the smallscale cloud processes and the basic laws that govern them to the general circulation of the atmosphere. These new types of observations, and simulation, are enabling researchers to distinguish how different cloud types influence the climate, and are guiding conceptual representations of their collective behaviour-- |
| feedback loop definition environmental science: A Framework for K-12 Science Education National Research Council, Division of Behavioral and Social Sciences and Education, Board on Science Education, Committee on a Conceptual Framework for New K-12 Science Education Standards, 2012-02-28 Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments. |

| feedback loop definition environmental science: The Uninhabitable Earth David Wallace-Wells, 2019-02-19 #1 NEW YORK TIMES BESTSELLER • “The Uninhabitable Earth hits you like a comet, with an overflow of insanely lyrical prose about our pending Armageddon.”—Andrew Solomon, author of The Noonday Demon NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The New Yorker • The New York Times Book Review • Time • NPR • The Economist • The Paris Review • Toronto Star • GQ • The Times Literary Supplement • The New York Public Library • Kirkus Reviews It is worse, much worse, than you think. If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible—food shortages, refugee emergencies, climate wars and economic devastation. An “epoch-defining book” (The Guardian) and “this generation’s Silent Spring” (The Washington Post), The Uninhabitable Earth is both a travelogue of the near future and a meditation on how that future will look to those living through it—the ways that warming promises to transform global politics, the meaning of technology and nature in the modern world, the sustainability of capitalism and the trajectory of human progress. The Uninhabitable Earth is also an impassioned call to action. For just as the world was brought to the brink of catastrophe within the span of a lifetime, the responsibility to avoid it now belongs to a single generation—today’s. LONGLISTED FOR THE PEN/E.O. WILSON LITERARY SCIENCE WRITING AWARD “The Uninhabitable Earth is the most terrifying book I have ever read. Its subject is climate change, and its method is scientific, but its mode is Old Testament. The book is a meticulously documented, white-knuckled tour through the cascading catastrophes that will soon engulf our warming planet.”—Farhad Manjoo, The New York Times “Riveting. . . . Some readers will find Mr. Wallace-Wells’s outline of possible futures alarmist. He is indeed alarmed. You should be, too.”—The Economist “Potent and evocative. . . . Wallace-Wells has resolved to offer something other than the standard narrative of climate change. . . . He avoids the ‘eerily banal language of climatology’ in favor of lush, rolling prose.”—Jennifer Szalai, The New York Times “The book has potential to be this generation’s Silent Spring.”—The Washington Post “The Uninhabitable Earth, which has become a best seller, taps into the underlying emotion of the day: fear. . . . I encourage people to read this book.”—Alan Weisman, The New York Review of Books |

| feedback loop definition environmental science: Business Models for Sustainability Peter E. Wells, 2013-10-01 Business Models for Sustainability breaks new ground by combining three important insights. First, achieving sustainability requires socio-technical transitions that entail new technologies, production processes, lifestyles, and consumption patterns. Second, firms play crucial roles in mediating between sustainable production and consumption. Third, radical innovations require organizational innovations and new business models. Peter Wells successfully combines these big picture ideas with rich in-depth case studies drawing on years of accumulated expertise. Highly recommended. Frank W. Geels, University of Manchester, UK and Chairman of the Sustainability Transitions Research Network With increasing awareness that innovative technology alone is insufficient to make sustainable lifestyles a reality, this book brings into sharp focus the need to create radical new business models. This insightful book provides a theoretically grounded but also realistic account of how the design of business models can be a critical component in the overall transition to sustainability, and one that transcends the usual focus on innovative technology. Weaving together key principles and components for business sustainability, the book highlights five very different pathways to the future for sectors ranging from microbreweries and printing through to clothing, mobility and plastics. Business has only just started the first few tentative steps towards a very different approach to creating and sustaining value, but this book concludes that enormous opportunities will emerge alongside new ways of creating and capturing value. Academics and postgraduate students in the fields of sustainable business, business organisations and industrial ecology will find this book brings a greater understanding of business strategy and structure to the discipline. While traditionally referenced and structured, this academic book is accessibly written with key principles that may also appeal to the consultant community. |

| feedback loop definition environmental science: From Molecules to Minds Institute of Medicine, Board on Health Sciences Policy, Forum on Neuroscience and Nervous System Disorders, 2008-12-07 Neuroscience has made phenomenal advances over the past 50 years and the pace of discovery continues to accelerate. On June 25, 2008, the Institute of Medicine (IOM) Forum on Neuroscience and Nervous System Disorders hosted more than 70 of the leading neuroscientists in the world, for a workshop titled From Molecules to Minds: Challenges for the 21st Century. The objective of the workshop was to explore a set of common goals or Grand Challenges posed by participants that could inspire and rally both the scientific community and the public to consider the possibilities for neuroscience in the 21st century. The progress of the past in combination with new tools and techniques, such as neuroimaging and molecular biology, has positioned neuroscience on the cusp of even greater transformational progress in our understanding of the brain and how its inner workings result in mental activity. This workshop summary highlights the important issues and challenges facing the field of neuroscience as presented to those in attendance at the workshop, as well as the subsequent discussion that resulted. As a result, three overarching Grand Challenges emerged: How does the brain work and produce mental activity? How does physical activity in the brain give rise to thought, emotion, and behavior? How does the interplay of biology and experience shape our brains and make us who we are today? How do we keep our brains healthy? How do we protect, restore, or enhance the functioning of our brains as we age? |

| feedback loop definition environmental science: Environmental Literacy in Science and Society Roland W. Scholz, 2011-07-21 In an era where humans affect virtually all of the earth's processes, questions arise about whether we have sufficient knowledge of human-environment interactions. How can we sustain the Earth's ecosystems to prevent collapses and what roles should practitioners and scientists play in this process? These are the issues central to the concept of environmental literacy. This unique book provides a comprehensive review and analysis of environmental literacy within the context of environmental science and sustainable development. Approaching the topic from multiple perspectives, it explores the development of human understanding of the environment and human-environment interactions in the fields of biology, psychology, sociology, economics and industrial ecology. The discussion emphasises the importance of knowledge integration and transdisciplinary processes as key strategies for understanding complex human-environment systems (HES). In addition, the author defines the HES framework as a template for investigating sustainably coupled human-environment systems in the 21st century. |
| feedback loop definition environmental science: The Gaia Hypothesis Michael Ruse, 2013-09-25 “The book is full of empathetic, insightful, and often very funny portraits of Margulis, Lovelock, and a community of other figures associated with Gaia.” —Carla Nappi, New Books in Science, Technology, and Society In 1965 English scientist James Lovelock had a flash of insight: the Earth is not just teeming with life; the Earth, in some sense, is life. He mulled this revolutionary idea over for several years, first with his close friend the novelist William Golding, and then in an extensive collaboration with the American scientist Lynn Margulis. In the early 1970s, he finally went public with the Gaia hypothesis, the idea that everything happens for an end: the good of planet Earth. Lovelock and Margulis were scorned by professional scientists, but the general public enthusiastically embraced Lovelock and his hypothesis. In The Gaia Hypothesis, philosopher Michael Ruse, with his characteristic clarity and wit, uses Gaia and its history, its supporters and detractors, to illuminate the nature of science itself. Gaia emerged in the 1960s, a decade when authority was questioned and status and dignity stood for nothing, but its story is much older. Ruse traces Gaia’s connection to Plato and a long history of goal-directed and holistic—or organicist—thinking and explains why Lovelock and Margulis’s peers rejected it as pseudoscience. But Ruse also shows why the project was a success. He argues that Lovelock and Margulis should be commended for giving philosophy firm scientific basis and for provoking important scientific discussion about the world as a whole, its homeostasis or—in this age of global environmental uncertainty—its lack thereof. “[Ruse’s] treatment is thought-provoking and original, as you would expect from this perceptive, irrepressible philosopher of biology.” —New Scientist |
| feedback loop definition environmental science: Devolution Max Brooks, 2020-06-16 NEW YORK TIMES BESTSELLER • The #1 New York Times bestselling author of World War Z is back with “the Bigfoot thriller you didn’t know you needed in your life, and one of the greatest horror novels I’ve ever read” (Blake Crouch, author of Dark Matter and Recursion). FINALIST FOR THE LOCUS AWARD As the ash and chaos from Mount Rainier’s eruption swirled and finally settled, the story of the Greenloop massacre has passed unnoticed, unexamined . . . until now. The journals of resident Kate Holland, recovered from the town’s bloody wreckage, capture a tale too harrowing—and too earth-shattering in its implications—to be forgotten. In these pages, Max Brooks brings Kate’s extraordinary account to light for the first time, faithfully reproducing her words alongside his own extensive investigations into the massacre and the legendary beasts behind it. Kate’s is a tale of unexpected strength and resilience, of humanity’s defiance in the face of a terrible predator’s gaze, and, inevitably, of savagery and death. Yet it is also far more than that. Because if what Kate Holland saw in those days is real, then we must accept the impossible. We must accept that the creature known as Bigfoot walks among us—and that it is a beast of terrible strength and ferocity. Part survival narrative, part bloody horror tale, part scientific journey into the boundaries between truth and fiction, this is a Bigfoot story as only Max Brooks could chronicle it—and like none you’ve ever read before. Praise for Devolution “Delightful . . . [A] tale of supernatural mayhem that fans of King and Crichton alike will enjoy.”—Kirkus Reviews (starred review) “The story is told in such a compelling manner that horror fans will want to believe and, perhaps, take the warning to heart.”—Booklist (starred review) |
| feedback loop definition environmental science: Uncertainty and Feedback Glenn Vinnicombe, 2001 The principal reason for using feedback is to reduce the effect of uncertainties in the description of a system which is to be controlled. H[infinity] loop-shaping is emerging as a powerful but straightforward method for designing robust feedback controllers for complex systems. However, in order to use this, or other modern design techniques, it is first necessary to generate an accurate model of the system (thus appearing to remove the reason for needing feedback in the first place). The v-gap metric is an attempt to resolve this paradox - by indicating in what sense a model should be accurate if it is to be useful for feedback design. This book develops in detail the H[infinity] loop-shaping design method, the v-gap metric and the relationship between the two, showing how they can be used together for successful feedback design. |
| feedback loop definition environmental science: Op Amps for Everyone Ron Mancini, 2003 The operational amplifier (op amp) is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits. |
| feedback loop definition environmental science: Rangeland Systems David D. Briske, 2017-04-12 This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions. |
