Does (climate) science need to be consensual to be authoritative?

(27 February)  “Does (climate) science need to be consensual to be authoritative?”   You can view my talk here which was given on Wednesday 6 February 2013 at the STEPS Centre Conference on ‘Credibility across cultures‘.  A longer version of this is being prepared for a book, but I have posted here a summary of my argument.  It has also been picked up by UK Research Fortnight publication.
