Didn’t someone say “You can’t make a cherry pie without using cherries”
That was Rosanne D’Arrigo. I also liked Esper et al 2003:
Do I understand this?
Mann claims to have hundreds of proxies but in the recent period he has only 55 with values. These are chosen with an unknown criteria. The remaining proxies are given values that are just weighted values of the chosen 55. So in reality, his hickey stick is the outcome of a specifically chosen set of 55 proxies.
The hockey stick is not the result of a measurement but of a method of construction.
Is this correct?
As I understand it, all of the above are true. In addition, he splices the temperature record on, and then uses non-published statistical methods to process them.
Mann-made global warming … de-dum.
Mann made warming!… I like that. I it a lot. That has set me chuckling for the rest of the day. 🙂
A good piece of work from Jeff Id.
If his analysis stands up, not only are the wheels off the wagon, but the horses are dead.
This is too unbelievable to believe and that’s probably also what those who get lost at the word statistics are thinking.
This is kind of amusing. Jeff Id’s work is on icecap.us mislabelled as Ian Jolliffe’s.

#(. I’ve sent a message to them urging them to correct this right away. I try to maintain a tone of irony rather than accusation and not to speculate on motives. Whether something was done intentionally or just because of goofiness is immaterial to the existence of an error. No one is ever going to be able to find out whether something was done intentionally or not. So it is a waste of breath and energy making such accusations. All that is relevant is whether the method is erroneous. People can draw their own conclusions. I’ve emailed them, suggesting that they restrain their language.
Re: Steve McIntyre (#10),
It looks like Joe changed the title, too, Steve.
==========================
They’ve already fixed it. Maybe we’ll get the rain in Maine fixed some day.

Is the internet not beautiful? No excuse whatosever these days for footdragging, non-compliance.
