Engagements

  • Interviewed by Anil Ananthaswamy in July 2010 for New Scientist Article on the challenges of climate modelling. In particular what are the major sources of uncertainty. The article appeared in the January 2011 New Scientist, June 2010
  • Interviewed in January 2011 by Richard Alleyne of the Daily Telegraph to comment on Manoj Joshi's article on El Nino and the Ashes following England's win in Australia. Article appeared in the Telegraph on Saturday 8th January., January 2011
  • Interviewed by Alex Gore from the Reading Chronicle on El Nino and the Ashes as a follow up to a Daily Telegraph article, although this was not carried by the paper in the end. We also spoke about the flooding in Queensland at the time, the Chronicle followed this up by interviewing a colleague (Nick Klingaman) which resulted in extensive media coverage., January 2011
