Mike’s Nature trick

So far one of the most circulated e-mails from the CRU hack is the following from Phil Jones to the original hockey stick authors - Michael Mann, Raymond Bradley, and Malcolm Hughes.

"Dear Ray, Mike and Malcolm,

Once Tim’s got a diagram here we’ll send that either later today or

first thing tomorrow.

I’ve just completed Mike’s Nature trick of adding in the real temps

to each series for the last 20 years (ie from 1981 onwards) amd from

1961 for Keith’s to hide the decline. [emphasis added] Mike’s series got the annual

land and marine values while the other two got April-Sept for NH land

N of 20N. The latter two are real for 1999, while the estimate for 1999

for NH combined is +0.44C wrt 61-90. The Global estimate for 1999 with

data through Oct is +0.35C cf. 0.57 for 1998.

Thanks for the comments, Ray.

Cheers

Phil"
