Bottom line: the โno upward trendโ has to continue for a total of 15 years before we get worried.
Phil JonesI've just completed Mike's [Mann] Nature trick of adding in the real temps to each series for the last 20 years (i.e. from 1981 onwards) and from 1961 for Keith's [Briffa] to hide the decline.
Phil JonesMike [Mann], can you delete an e-mails you may have had with Keith [Trenberth] re AR4? Keith will do likewise...Can you also e-mail Gene and get him to do the same? I don't have his e-mail address...We will be getting Caspar to do likewise.
Phil JonesYou might want to check with the IPCC Bureau. I've been told that IPCC is above national FOI Acts. One way to cover yourself and all those working in AR5 [the upcoming IPCC Fifth Assessment Report] would be to delete all e-mails at the end of the process. Hard to do, as not everybody will remember it.
