Wow! It looks like there has now been a major backdown by the authors of the original "Greenhouse" article. The crooked scientists behind the Greenhouse scare (Mann, Bradley and Hughes) have at last been forced to own up to fudging their data. The very foundation of the "greenhouse" scare has been kicked away....a clear admission that the disclosure of data and methods behind MBH98 was materially inaccurate. The text acknowledges extensive errors in the description of the data set. Even more important is the new online Supplementary Information (SI) site, which concedes for the first time that key steps in the computations behind MBH98 were left out of (and indeed conflict with) the description of methods in the original paper.But the scientists behind the original study are still fighting, of course
The Corrigendum and the SI contain the gratuitous claim that the errors, omissions and misrepresentations in MBH98 do not affect their results. If this were true, then a simple constructive proof could have been provided, showing before and after calculations. This is conspicuously missing from the Corrigendum and the new SI. We have done the calculations and can assert categorically that the claim is false.But even if these guys rolled over and admitted that at best they'd goofed, don't expect greens to shut up. They'll try honesty, but if that doesn't work they'll try something else.
