cc: "Sear, Chris (CEOSA)" , "Warrilow, David (CEOSA)" , "Munro, Paul (CEOSA)" date: Thu, 25 Sep 2008 13:35:43 +0100 from: "Thorpe, Jo (CEOSA)" subject: CONFIDENTIAL: Response to David Holland to: "Phil Jones" , "Mitchell, John FB (Chief Scientist)" Dear John and Phil, Defra has received a letter from David Holland regarding the `hockey stick' graph and its handling by the IPCC. We have drafted a short response, and would be grateful if you could read it and send us any comments you have. In particular, we would like to know whether you are happy with the penultimate paragraph (thereby justifying the final comment about advice from Met Office/CRU). Please also let me know if you feel that we should include any more information in defence of the hockey stick, including a more comprehensive discussion of the latest paper by Mann et al. (my instinct is that it would be best to avoid this in order to discourage further communication, but let me know if you feel otherwise). I have attached the letter from David Holland for your information - please treat this as strictly confidential. It would be very helpful if you could provide comments by Wednesday next week so that we can respond before the deadline. Many thanks for your help, Jo Thorpe <<20080925_Letter to Holland.doc>> <> ______________________ Joanna Thorpe Climate Science and Stratospheric Ozone Team Climate, Energy and Ozone: Science and Analysis (CEOSA) Division Department for Environment, Food and Rural Affairs Zone 3E, Ergon House, Horseferry Road, London, SW1P 2AL Tel: 0207 238 3384 Department for Environment, Food and Rural Affairs (Defra) This email and any attachments is intended for the named recipient only.
