   Dear Phil



   This old and very dated chestnut. You were going to find out more if you could. You know my
   part of the story - it goes back to a Defra (then DOE) publication (which it would be nice
   to identify) and was requested in the Govt review by David Warrilow. )Likely based in part
   on Lambs CET work with some subjective alterations?).



   Any further insights would be helpful.



   Cheers



   Chris

   Subject: IPCC report

   Dear Professor Folland



   Sir John Houghton suggested that I should contact you. I have been having an exchange of
   e-mail messages with Martin Durkin, who produced the programme 'The Great Global Warming
   Swindle' that was screened on Channel 4 in March. In particular, I have been challenging
   him about his use of a figure that he attributed to the IPCC First Assessment Report in
   1990. It appears as Figure 7.1c on page 202 of the IPCC report, and shows global
   temperatures were higher during the Medieval Warm Period. I would be interested in finding
   out where this figure was obtained from - it closely resembles some of the figures
   published by Hubert Lamb, except that he was concerned with the temperature in Central
   England. Any light that you may be able to cast on this issue would be greatly appreciated.
   I should stress that I am primarily concerned about the extent to which Durkin has
   misrepresented the scientific evidence and the work of researchers - I have complained to
   Ofcom about the programme and I organised a joint letter to him from researchers in April
   asking him not to distribute it on DVD without correcting the substantial errors in it:
