More than half the globe is covered by visible clouds. Clouds control major parts of the Earth’s energy balance, influencing both incoming shortwave solar radiation and outgoing longwave thermal radiation. Latent heating and cooling related to cloud processes modify atmospheric circulation, and, by modulating sea surface temperatures, clouds affect the oceanic circulation. They are also an essential component of the global water cycle, on which all terrestrial life depends. Yet clouds constitute the most poorly quantified, least understood, and most puzzling aspect of atmospheric science, and thus the largest source of uncertainty in the prediction of climate change. Because they are influenced by climate change, and because complex, unidentified feedback systems are involved, science is faced with many unanswered questions. This book begins by identifying and describing the baffling nature of clouds. It explores the boundaries of current knowledge on the spatial/temporal variability of clouds and cloud-related aerosols, as well as the factors that control clouds, and examines the extent and nature of anthropogenic perturbations. Particular emphasis is placed on the connections of clouds to climate through radiation, dynamics, precipitation, and chemistry, and on the difficulties in understanding the obvious but elusive fact that clouds must be affected by climate change. The book offers recommendations to improve the current state of knowledge and to direct future research in fields ranging from chemistry and theoretical physics to climate modeling and remote satellite sensing.

Debates over post-Kyoto Protocol climate change policy often take note of two issues: the feasibility and desirability of international cooperation on climate change policies, given the failure of the United States to ratify Kyoto, and the very limited involvement of developing countries; and the optimal timing of climate policies. This book offers insights into both of these concerns. It first considers the appropriate institutions for effective international cooperation on climate change, proposing an alternative to the Kyoto arrangement and a theoretical framework for such a scheme. The discussions then turn to the stability of international environmental agreements, emphasizing the logic of coalition forming (including the applicability of game-theoretical analysis). Finally, chapters address both practical and quantitative aspects of policy design, offering theoretical analyses of such specific policy issues as intertemporal aspects of carbon trade and the optimal implementation of a sequestration policy and then using formal mathematical models to examine policies related to the rate of climate change, international trade and carbon leakage, and the shortcomings of the standard Global Warming Potential index.

Predictions about global climate change have produced both stark scenarios of environmental catastrophe and purportedly pragmatic ideas about adaptation. This book takes a different perspective, exploring the idea that the challenge of adapting to global climate change is fundamentally an ethical one, that it is not simply a matter of adapting our infrastructures and economies to mitigate damage but rather of adapting ourselves to realities of a new global climate. The challenge is to restore our conception of humanity—to understand human flourishing in new ways—in an age in which humanity shapes the basic conditions of the global environment. In the face of what we have unintentionally done to Earth’s ecology, who shall we become? The contributors examine ways that new realities will require us to revisit and adjust the practice of ecological restoration; the place of ecology in our conception of justice; the form and substance of traditional virtues and vices; and the organizations, scale, and underlying metaphors of important institutions. Topics discussed include historical fidelity in ecological restoration; the application of capability theory to ecology; the questionable ethics of geoengineering; and the cognitive transformation required if we are to “think like a planet.”

Climate change will shape the political, economic, and cultural landscape as surely as it shapes the natural landscape. It challenges our existing political institutions, ethical theories, and ways of conceptualizing the human relationship to the environment, it defies current principles of distributive justice, transcends current discourses on rights, and disrupts our sense of place. This book argues that the conceptual tools of political theory can help us understand the obstacles to fair and effective global climate change policies, and offers a selection of scholarly efforts to do so. Illuminating the variety of political, economic, and social problems caused by global warming, the book applies a range of theoretical approaches and methodologies—from analytic philosophy and constitutional and legal theory to neo-Marxism and critical theory—using climate change as a case to test standard normative and empirical premises. It first looks at distributive justice concerns raised by climate change, including allocation of the global atmospheric commons and how to establish the basis for a fair and effective global climate policy regime, then examines the complex relationships between climate change and society, including the way that social institutions and practices construct, reinforce, aim to address, and are disrupted by climatic instability. Showing how political theory challenges and is challenged by global climate change, the book both demonstrates and evaluates innovative approaches in the developing field of environmental political theory.

After nearly a quarter century of international negotiations on climate change, we stand at a crossroads. A new set of agreements is likely to fail to prevent the global climate's destabilization. Islands and coastlines face inundation, and widespread drought, flooding, and famine are expected to worsen in the poorest and most vulnerable countries. How did we arrive at an entirely inequitable and scientifically inadequate international response to climate change? Combining rich empirical description with a political economic view of power relations, the chapters in this book document the struggles of states and social groups most vulnerable to a changing climate and describe the emergence of new political coalitions that take climate politics beyond a simple North–South divide. They offer six future scenarios in which power relations continue to shift as the world warms. A focus on incremental market-based reform, they argue, has proven insufficient for challenging the enduring power of fossil fuel interests, and will continue to be inadequate without a bolder, more inclusive and aggressive response.

This is a multidisciplinary reexamination of the Gaia hypothesis, which was introduced by James Lovelock and Lynn Margulis in the early 1970s. The Gaia hypothesis holds that Earth’s physical and biological processes are linked to form a complex, self-regulating system, and that life has affected this system over time. Until a few decades ago, most of the earth sciences viewed the planet through disciplinary lenses: biology, chemistry, geology, atmospheric, and ocean studies. The Gaia hypothesis, on the other hand, takes a very broad interdisciplinary approach. Its most controversial aspect suggests that life actively participates in shaping the physical and chemical environment on which it depends in a way that optimizes the conditions for life. Despite initial dismissal of the Gaian approach as New Age philosophy, it has today been incorporated into mainstream interdisciplinary scientific theory, as seen in its strong influence on the field of Earth System Science. This book provides a multi-faceted examination of Gaia as science and addresses significant criticism of, and changes in, the hypothesis since its introduction. Chapters explore the scientific, philosophical, and theoretical foundations of Gaia. They address such topics as the compatibility of natural selection and Gaian processes, Gaia and the “thermodynamics of life,” the role of computer models in Gaian science (from James Lovelock’s famous but controversial “Daisyworld” to more sophisticated models that use the techniques of artificial life), pre-Socratic precedents for the idea of a “Living Earth,” and the climate of the Amazon Basin as a Gaian system.
