(21 May)  Two new pre-publication manuscripts:  a review article for Progress in Physical Geography on ‘Climate engineering through stratospheric aerosol injection‘ and a chapter ‘How climate models gain and exercise authority‘ for a forthcoming Routledge book edited by Kirsten Hastrup and Martin Skrydstrup   ‘The social life of climate change models: anticipating nature’.  This latter is a written-up version of my talk in September 2010 to the Cambridge CASSH meeting ‘Challenging models in the face of uncertainty’.
