Christopher Preston has emerged as a leading philosopher of the ethics of climate engineering. In this new collection of essays, he has brought together a diverse group of thinkers and analysts from across three continents who wrestle with the complex question, ‘In what ways might it be just to deliberately engineer the world’s climate?’ Preston’s Climate Justice and Geoengineering shows that in the Anthropocene the human ability to transform nature will always likely exceed our confidence in whether it is morally right to do so.

It is likely that we will all have to grapple with the political and ethical implications of climate engineering as calls for an aerosol sunscreen to coat the Earth become louder. Christopher Preston has brought together an impressive group of thinkers to reflect on the knottiest problem of geoengineering: can it be done justly and, if not, must we do it anyway?

Responding to the risks of climate change management requires attention to coupled scientific and ethical concerns. Nowhere is this more obvious than proposals to engineer the climate through measures like cooling the planet through deployment of stratospheric aerosols. Climate Justice and Geoengineering makes an important contribution to this complex and controversial approach to climate risk management, one that promises to responsibly inform both practices and policy.

This important collection situates its thoughtful contributions on climate justice and geoengineering within the context of real-world climate policy choices. It thereby provides a much-needed reflection on the implications of considering geoengineering as a potential policy option amongst others, and is excellent reading for anyone interested in the difficult choices that contemporary climate policy must face.
