Book excerpt: A brief investigation is presented of long-term variability of the tropical heat supply of the Pacific Ocean and its influence on the atmospheric circulation. From the record of monthly sea and air temperature at Canton Island, 2 deg 48 min S, 171 deg 43 min W, November 1964 is selected as typifying the arid conditions associated with anomalously cold equatorial water, and as representing a contrast to November 1965 with its near-maximum water temperature and abundant rainfall. Air circulation also differs significantly here. The large-scale effect on the atmosphere from November 1964 to November 1965 is described as a general warming of the complete belt of the tropical troposphere with inherent strengthening of the upper tropospheric westerlies in both hemispheres.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change can reasonably be expected to increase the frequency and intensity of a variety of potentially disruptive environmental events-slowly at first, but then more quickly. It is prudent to expect to be surprised by the way in which these events may cascade, or have far-reaching effects. During the coming decade, certain climate-related events will produce consequences that exceed the capacity of the affected societies or global systems to manage; these may have global security implications. Although focused on events outside the United States, Climate and Social Stress: Implications for Security Analysis recommends a range of research and policy actions to create a whole-of-government approach to increasing understanding of complex and contingent connections between climate and security, and to inform choices about adapting to and reducing vulnerability to climate change.

Book excerpt: Economic development, population growth and poor resource management have combined to alter the planet's natural environment in dramatic and alarming ways. The field of environmental security has matured in response to improved scientific understanding of the causes and trends of global environmental change. Research conducted in the past two decades has grappled with this core set of questions in a variety of ways, generating findings and hypotheses that have stimulated considerable intellectual and policy activity. This volume takes stock of the research, and organizes it into a framework, described in the first chapter of the volume, that clarifies its achievements as well as identifies its weaknesses and gaps. This is followed by seven chapters representing the various ways in which environmental change and security have been linked, and including the principal critiques of this linkage. A third section explores six key issue areas: water, population, development, food, energy and climate change. The book concludes with a chapter on the future of environmental security.

Book excerpt: The paper presents a numerical investigation of a bounded ocean basin on the spherical earth, with particular attention directed to the role of planetary circulations. The time-dependent primitive equations are solved for a shallow, wind-driven, homogeneous ocean in a basin of uniform depth on the sphere. In a series of comparative numerical solutions, it is shown that at least a 2-degree resolution is needed to resolve the western boundary currents adequately and to avoid undue distortion of the transient Rossby waves. Although the transient Rossby waves systematically produce a momentum flux convergence at the latitude of the maximum eastward current, this is only a relatively small contribution to the zonal oceanic momentum balance; the bulk of the mean zonal stress is balanced by a nearly stationary net pressure torque exerted against the meridional boundaries by the wind-raised water.

Book excerpt: The report contains sections on scaling and calibration, variation of the wind stress parameter to check the calibrated model, and variation of the vertical thermal diffusion parameter. Results are discussed in terms of heat balance components. The temperature distributions calculated are in qualitative agreement with the more detailed numerical model of Bryan and Cox. An increasingly pronounced subtropical high temperature pattern with an increasing wind stress parameter is a feature common to both models. A new result is the lack of appreciable differences in temperature distributions with or without vertical thermal diffusion. (Author).

Book excerpt: Severe droughts, damaging floods and mass migration: Climate change is becoming a focal point for security and conflict research and a challenge for the world’s governance structures. But how severe are the security risks and conflict potentials of climate change? Could global warming trigger a sequence of events leading to economic decline, social unrest and political instability? What are the causal relationships between resource scarcity and violent conflict? This book brings together international experts to explore these questions using in-depth case studies from around the world. Furthermore, the authors discuss strategies, institutions and cooperative approaches to stabilize the climate-society interaction.

Book excerpt: The report describes results of a simulation of a wind-driven homogeneous ocean and its characteristic circulation. From time-dependent numerical solutions of the model, a negative lateral eddy viscosity is estimated in the basin interior, where flow is dominated by transient Rossby waves. These waves produce a systematic meridional convergence of eddy momentum into the latitudes of mean eastward current and are analogous to the Rossby waves in the general circulation of the atmosphere. This regime exists in spite of the formally prescribed lateral viscosity in the model's equations; the required viscous dissipation apparently occurs in the standing waves of the western boundary current system. Results suggest that a strong gradient of the effective eddy viscosity may be characteristic of an ocean with meridional boundaries. This investigation was begun as part of an effort to evaluate the effects of environmental perturbations that could be detrimental to the security and welfare of our nation.

Download or read book Climate Security in the Anthropocene written by Judith Nora Hardt and published by Springer Nature. This book was released on 2023-05-20 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The speed and scale of climate change presents unique and potentially monumental security implications for individuals, future generations, international institutions and states. Long-dominant security paradigms and policies may no longer be appropriate for dealing with these new security risks of the Anthropocene. In response to this phenomenon, this book investigates how states have reacted to these new challenges and how their different understandings of the climate-security nexus might shape global actions on climate change. It focuses on the perceptions, framings, and policies of climate security by members of the United Nations Security Council (UNSC), the world's highest ranking multilateral security forum. Empirically, the book presents detailed, bottom-up case studies from local authors of every UNSC member state in 2020. It combines this with an innovative theoretical approach spanning national, human and ecological security that helps to capture the complex dynamics of state-led approaches to dealing with security in the Anthropocene. This book therefore offers readers a compelling picture of climate-security politics in the UNSC, beyond Council debates and resolutions. By comparing and contrasting how different framings of climate security impact various policy sectors of members states, the authors are able to assess the barriers and opportunities for addressing climate security locally and globally. “This timely contribution to the literature on climate security examines the under-analysed relationship between the policy approaches of key countries at the national, and at the international level. Policy alignment at multiple levels of governance will be critical if we are to respond adequately to the ubiquitous challenges posed by climate change and variability.” Shirley Scott, Head of School and Professor, School of Humanities and Social Sciences, UNSW Canberra at the Australian Defence Force Academy (Australia). "Climate change is increasingly considered a problem of 'security', yet what that means remains deeply contested. Behind the rhetoric of 'climate crisis’, threats and 'emergencies’, UN Security Council members offer profoundly different ideas about what climate change – and security – mean, and what should be done about it. This book brilliantly lays out the hidden or overlooked divergences of interests and perspectives on 'climate security' that are playing out in the world's most central security institution, as it grapples with securing a climate unstable world." Olaf Corry, Professor of Global Security Challenges, Faculty of Social Sciences, School of Politics and International Studies, University of Leeds (United Kingdom). "Security is a contested concept, whose scope and direction are subject to change. The prime value of this volume is the systematic documentation of the dynamics in defining what security is about in reaction to ever dramatic climate change. The book's focus on a somewhat representative sample of states – the members of the Security Council – provides robust evidence that even though many governments remain reluctant to retreat from traditional perceptions of security, there is a large and growing acceptance of the need to adjust priorities in providing security in response to climate change and its consequences." Michael Brzoska, Professor and Senior Research Fellow, IFSH Institute for Peace Research and Security Policy, Universität Hamburg (Germany). "The climate security literature has often been labelled as West-centric with little recognition of knowledge production processes, and different historical, socio-economic, and political experiences of various societies in the Global South. This book goes beyond the conventional approaches to provide a whole range of perspectives on climate security reflective of diverse contextual realities – covering factors such as development imperatives, conflict dynamics, postcolonial legacies, institutional/actor complexities, and geopolitical contestations, among others. By focusing on the climate security approaches of various countries (case studies) at the domestic and international levels, the applicability of existing climate security frameworks (or lack thereof) in the context of these case studies is brilliantly brought out by the chapters. This book weaves together these diverse perspectives by providing a comprehensive overview of climate security-related policies of countries from both Global South and Global North; and their positions on climate change and security in the UNSC. They reflect the varying norms, interests, priorities, and challenges that continue to shape the climate security agenda within the UNSC as well as non-UNSC platforms. This book is a must read for anyone interested in gaining an in-depth and invigorating understanding of the evolution of distinct climate security discourses and practices in varying contexts." Dhanasree Jayaram, Assistant Professor, Department of Geopolitics and International Relations, Manipal Academy of Higher Education (MAHE) (India), Research Fellow. Centre Marc Bloch. "Climate Security in the Anthropocene provides a timely and compelling account of the conceptualizations of the climate security nexus and their implications. By considering climate security through the lenses of national, human and ecological security it provides a sophisticated account of the different dimensions involved in the UNSC debates and beyond. The collection of chapters illustrating the positions of the members of the UN Security Council in 2020, not only provide an informative account but also sheds light on the challenges that the UNSC faces in dealing with climate change." Maria Julia Trombetta, Associate Professor in Politics and Environment, School of International Studies, Institute of Asia and Pacific Studies, University of Nottingham Ningbo China (China). "The book “Climate Security in the Anthropocene” is the first systematic assessment of climate security decision-making and governance of the UN Security Council. It is groundbreaking as it combines empirical bottom-up case studies of perceptions and policies of different ministries and governmental agencies of UNSC member states with a novel theoretical framework contrasting different security framings and conceptions in the Anthropocene. Discussing various policy sectors, the study assesses barriers and opportunities and provides novel insights on multi-scale responses and interactions in the climate-security nexus from local to global levels, connecting individuals, future generations, international institutions and states. The book is highly recommendable for everyone interested in the emerging field of policy-oriented climate-security research." Jürgen Scheffran, Professor for Integrative Geography, Head of the Research Group, “Climate Change and Security” (CLISEC), Center for Earth System Research and Sustainability, Universität Hamburg (Germany). "This volume provides multifocal insights into the climate/security nexus, combining critical security studies and international relations theories in the age of the Anthropocene. Analyzing the perceptions, policies, and positions of 15 UN Security Council member states, this thought-provoking piece demonstrates how national security, human security, and ecological security have advanced as conceptual innovations. Offering a rich and diverse range of empirical case studies, this piece is a strong contribution to academic discourse and teaching alike." Franziska MüllerJunior Professor for Political Science, Faculty of Business, Economics and Social Sciences, Universität Hamburg (Germany).

Available in PDF, EPUB and Kindle. Book excerpt: This book assesses the construction of security in the context of climate change, with a focus on the Arctic region. It examines and discusses changes in the security premises of the Arctic states, from traditional security to environmental and human security. In particular, the book explores how climate change impacts security discourses and premises as well as theoretically discussing the possibility for another change, from circumpolar stability into peaceful change. Chapters cover topics such as the ethics of climate change in the arctic, China’s emerging power and influence on arctic climate security, the discursive transformation of the definition of security and the intersection between urban, climate and Arctic studies. The book concludes with the question of whether a paradigm shift in our understanding of traditional security is possible, and whether it is already occurring in the Arctic.

This book was released on 2009 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Climate change, in which man-made global warming is a major factor, will likely have dramatic and long lasting consequences with profound security implications, making it a challenge the United States must urgently take up. The security implications will be most pronounced in places where the effects of climate change are greatest, particularly affecting weak states already especially vulnerable to environmental destabilization. Two things are vitally important: stemming the tide of climate change and adapting to its far-reaching consequences. This project examines the destabilizing effects of climate change and how the military could be used to mitigate global warming and to assist at-risk peoples and states to adapt to climate change, thereby promoting stability and sustainable security. Recommendations are made on the importance of U.S. leadership on the critical issue of global warming, on defining and dealing with the strategic dimensions of climate change, and, as a case in point, on how Sino-American cooperation in Africa would not only benefit areas where climate change effects are already pronounced, but also strengthen a crucial bilateral relationship."--Abstract.

Download or read book Rethinking Climate Change Conflict and Security written by Jan Selby and published by Routledge. This book was released on 2017-10-02 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is global climate change likely to become a significant source of violent conflict, and should it therefore be seen as a national security challenge? Most Northern governments, militaries, think tanks and NGOs believe so, as do many academic researchers, on the grounds that increased temperatures, changing precipitation patterns and rising sea levels will worsen existing social stresses, especially within poor societies and marginal communities across Africa and Asia. This book argues otherwise. The first collection of its kind, it brings together leading scholars of Anthropology, Geography, Development Studies and International Relations to provide a series of critical analyses of mainstream thinking on the climate-security nexus. It shows how policy discourse on climate conflict consistently misrepresents the causes of violence, especially by obscuring its core political dimensions. It demonstrates that quantitative research provides a flawed basis for understanding climate-conflict linkages. It argues that climate security discourse is in hoc with a range of questionable military, authoritarian and developmental agendas. And it reveals that the greening of global capitalism is already having violent consequences across the global South. Climate change, the book argues, does indeed have serious conflict and security implications – but these are quite different from how they are usually imagined. This book was published as a special issue of Geopolitics.

Available in PDF, EPUB and Kindle. Book excerpt: In the early years of the new millennium, hurricanes lashed the Caribbean and flooded New Orleans as heat waves and floods seemed to alternate in Europe. Snows were disappearing on Mount Kilimanjaro while the ice caps on both poles retreated. The resulting disruption caused to many societies and the potential for destabilizing international migration has meant that the environment has become a political priority.The scale of environmental change caused by globalization is now so large that security has to be understood as an ecological process. A new geopolitics is long overdue. In this book Simon Dalby provides an accessible and engaging account of the challenges we face in responding to security and environmental change. He traces the historical roots of current thinking about security and climate change to show the roots of the contemporary concern and goes on to outline modern thinking about securitization which uses the politics of invoking threats as a central part of the analysis. He argues that to understand climate change and the dislocations of global ecology, it is necessary to look back at how ecological change is tied to the expansion of the world economic system over the last few centuries. As the global urban system changes on a local and global scale, the world’s population becomes vulnerable in new ways. In a clear and careful analysis, Dalby shows that theories of human security now require a much more nuanced geopolitical imagination if they are to grapple with these new vulnerabilities and influence how we build more resilient societies to cope with the coming disruptions. This book will appeal to level students and scholars of geography, environmental studies, security studies and international politics, as well as to anyone concerned with contemporary globalization and its transformation of the biosphere.

Download or read book Climate Change Food Security and Natural Resource Management written by Mohamed Behnassi and published by Springer. This book was released on 2018-11-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to the on-going debates on climate change by focusing on the SDGs and exploring linkages between environmental change and food security as well as the relevance and need to consider the management of natural resources, especially water, soil and forest. Compared to relevant existing publications, this book covers case studies that capture the everyday realities of the local people and how they react and adapt to similar situations in different geographical settings. Each case study presented in this book gives a particular message. The strength of this book lies in the fact that it covers the most neglected topics in climate negotiations in spite of the fact that these decide the fate of millions of people around the world, especially the developing countries. By presenting a collection of case studies from Africa, Asia and Europe, this book encourages cross-continental knowledge sharing. The scope of the book ranges from impacts to mitigation and from in-field experiments to policy implementation. It contributes to the existing knowledge on climate-food nexus and connects climate change to sectors it could impact directly. All chapters in this book emphasise local ownership of strategy processes, effective participation from all levels, and high-level commitment. Besides being relevant for the academicians and scholars working in the field of climate change, forest and agriculture, it aims to catch interest of the policy makers and practitioners to understand ground realities for appropriate action. It is also bound to make an impact on the Non-Governmental Organizations around the world and in the three different continents that this book covers, considering the indigenous and local issues highlighted in this book.
