The last time I did this, R was a brand new language to me. After 6 months messing around in my free time I speak rudimentary R with a C accent. R is a totally free language that anyone can download and learn. This post is a demonstration of the methods behind the Mann08 CPS hockey stick reconstruction. The difference between this and the numerous posts I did before is better R programming and a lot more comments in the code. If youre serious about understanding vs advocating, you can figure this out. There is not one person I can think of who has ever commented here, incapable of figuring this out.
CPS is composite plus scale, which is an invented method for calibrating proxies to measured temperatures in paleoclimatology reconstructions. In paleoclimatology methods are too often invented to find the signal in the noise this is not a new problem and it stems from the large signal to noise ration of paleo-data. If you happen to be a paleoclimatologist who does temperature reconstructions, please try your methods on ARIMA data with a known signal before employing it on whatever your proxy is.
I have hundreds of new readers, who didnt get the day by day experience of my discovery of climatology math. Well some of my early work was a little rough, however it was correct and the specifics still stand uncriticized.
This post was prompted by some people in blogland (despite the complete lack of rational criticism) claiming that my demonstrations of the CPS hockey stick math is faulty rather than the actual hockey stick itself. An oddly reversed situation which could only exist in the new progressive anti-world.

NOTE that it was posted in June 2009, before the Hadley CRU leak.
(Mann is an American AGW proponent, famous for the Hockey-stick graph, currently at Penn State. It seems his name has come up in connection with the Hadley CRU emails as well.)
Cheers!
"Hadley CRU has apparently been hacked [epic fraud?]"

--Open this chart in another window
--On the "x-axis" find "MAY"
--Follow "May" up to the color for 2009
Now, did you notice? Good for you, that's right! May 2009 had the most square kilometers of ice in the past 8 years.
Now tell your friends, and show them how to read a cartesian chart.
Nicely Done.
