Participants: Prof David Keith (Harvard) and Prof Mike Hulme (King's College London). The debate will focus on solar geoengineering - proposed techniques to reflect a proportion of the sun's radiation back into space to counteract some of the effects of climate change. Professor Keith has recently published a book entitled "The Case for Climate Engineering", while Professor Hulme will be publishing a book on climate engineering with a contrasting viewpoint, in April next year. The event is being organised by the Oxford Geoengineering Programme, an initiative of the Oxford Martin School, at the University of Oxford.
