It is already known that climate engineering raises numerous troubling ethical issues. The pertinent question yet to be addressed is how the issues of potential injustice raised by climate engineering compare to those raised by alternative proposals for tackling climate change. This volume is the first to put the issues raised by climate engineering into a comprehensive, comparative context so that the key ethical issues associated with climate engineering can be better measured against the ethics of alternative proposals for tackling climate change. Addressing the topic specifically in the frame of justice, the book represents both advocates of climate intervention research and its sceptics. The volume includes a helpful blend of the theoretical and the practical, with issues of morality are at its heart, and contributions from authors in philosophy, communications studies, engineering, public policy, sustainable development studies, economics, and climate studies. This cross-disciplinary collection provides an important start on the difficult public policy decisions that lie ahead.
