Stabilizing the world’s climates means cutting carbon dioxide pollution. There’s no way around it. But what if that’s not enough? What if it’s too difficult to accomplish in the time allotted or, worse, what if it’s so late in the game that even cutting carbon emissions to zero, tomorrow, wouldn’t do? Enter solar geoengineering. The principle is simple: attempt to cool Earth by reflecting more sunlight back into space. The primary mechanism, shooting particles into the upper atmosphere, implies more pollution, not less. If that doesn’t sound scary, it should. There are lots of risks, unknowns, and unknowables. In Geoengineering: The Gamble, climate economist Gernot Wagner provides a balanced take on the possible benefits and all-too-real risks, especially the so-called “moral hazard” that researching or even just discussing (solar) geoengineering would undermine the push to cut carbon emissions in the first place. Despite those risks, he argues, solar geoengineering may only be a matter of time. Not if, but when. As the founding executive director of Harvard’s Solar Geoengineering Research Program, Wagner explores scenarios of a geoengineered future, offering an inside-view of the research already under way and the actions the world must take to guide it in a productive direction.

Climate engineering is a dystopian project. But as the human species hurtles ever faster towards its own extinction, geoengineering as a temporary fix, to buy time for carbon removal, is a seductive idea. We are right to fear that geoengineering will be used to maintain the status quo, but is there another possible future after geoengineering? Can these technologies and practices be used to bring carbon levels back down to pre-industrial levels? Are there possibilities for massive intentional intervention in the climate that are democratic, decentralised, or participatory? These questions are provocative, because they go against a binary that has become common sense: geoengineering is assumed to be on the side of industrial agriculture, inequality and ecomodernism, in opposition to degrowth, renewable energy, sustainable agriculture and climate justice. After Geoengineering rejects this binary, to ask: what if the people seized the means of climate production? Both critical and utopian, the book examines the possible futures after geoengineering. Rejecting the idea that geoengineering is some kind of easy work-around, Holly Buck outlines the kind of social transformation that would be necessary to enact a programme of geoengineering in the first place.

Solar geoengineering could reduce climate change, but poses risks. This volume explores how it is, could, and should be governed.

The sobering reality of the disconnect between the resolve of the world community to effectively address climate change, and what actually needs to be done, has led to increasing impetus for consideration of a suite of approaches collectively known as “climate geoengineering,” or “climate engineering.” Indeed, the feckless response of the world community to climate change has transformed climate geoengineering from a fringe concept to a potentially mainstream policy option within the past decade. This volume will explore scientific, political and legal issues associated with the emerging field of climate geoengineering. The volume encompasses perspectives on both of the major categories of climate geoengineering approaches, carbon dioxide removal and solar radiation management.

The first book to focus on the legal aspects of climate engineering, making recommendations for future laws and governance.

This book takes a critical look at solar geoengineering as an acceptable means for addressing climate change. Baskin explores the assumptions and imaginaries which animate ‘engineering the climate’ and discusses why this climate solution is so controversial. The book explains geoengineering’s past, its revival in the mid-2000s, and its future prospects including its shadow presence in the Paris climate accord. The main focus however is on dissecting solar geoengineering today – its rationales, underpinning knowledge, relationship to power, and the stance towards nature which accompanies it. Baskin explores three competing imaginaries associated with geoengineering: an Imperial imaginary, an oppositional Un-Natural imaginary, and a conspiratorial Chemtrail imaginary. He seeks to explain why solar geoengineering has struggled to gain approval and why resistance to it persists, despite the support of several powerful actors. He provocatively suggests that reconceptualising our present as the Anthropocene might unwittingly facilitate the normalisation of geoengineering by providing a sustaining socio-technical imaginary. This book is essential reading for those interested in climate policy, political ecology, and science & technology studies.

Experiments in geoengineering – intentionally manipulating the Earth’s climate to reduce global warming – have become the focus of a vital debate about responsible science and innovation. Drawing on three years of sociological research working with scientists on one of the world’s first major geoengineering projects, this book examines the politics of experimentation. Geoengineering provides a test case for rethinking the responsibilities of scientists and asking how science can take better care of the futures that it helps bring about. This book gives students, researchers and the general reader interested in the place of science in contemporary society a compelling framework for future thinking and discussion.

In this book, eleven prominent authorities on climate change consider the legal, policy, and philosophical issues presented by geoengineering. The book asks: When, if ever, are decisions to embark on potentially risky climate modification projects justified? If such decisions can be justified, in a world without a central governing authority, who should authorize such projects and by what moral and legal right?

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.
