re: layers of wrong, dated from years ago
"The panel published its report in 2006.[28] The report agreed that there were statistical shortcomings in the MBH analysis, but concluded that they were small in effect."
Nice they admitted errors, but how could they possible conclude they were small in effect.
Name me one person who claims to have thoroughly review all the data. And more importantly where is this work published so that other people can examine it?
Trust me, lot's of people would want to see it.
And I have no doubt Steve McIntyre would be extremely happy to see it.
It shouldn't be necessary to prove that Mann made errors, in order to review his work, but since we have this established, let's look for other possible errors.
