This introduction to responsible innovation, as a new approach to governance, explains the broad sweep of technoscience that is brought under the umbrella of "geoengineering". The possibility of exerting control over the global climate introduces profound social, political and ethical questions. The book explores these issues through the lens of the research project SPICE (Stratospheric Particle Injection for Climate Engineering) one of the first major geoengineering studies worldwide. The book introduces recent 'experiments' in governance, involving new conversations with civil society and others, to explain science-in-society and suggest new ways forward. It illustrates broader dynamics that are of substantial relevance to both wider geoengineering debates and wider science and technology governance debates.
