CRU emails no 13 - not sure what to make of this

A few interesting statements in here, but I would really like to understand what they are talking about when they say "So the verification RE for the "censored" NH mean reconstruction? -6.64 The verification RE for the original MBH98 NH mean reconstruction: 0.42 I think the case is really strong now!"

From: "Michael E. Mann"

Hi Keith,

sorry--yes, I think the Nature idea would be great. Definitely give it a try!

Things obviously moving over there - this result looks good.Just thought I'd send this first bit (up to dotted line) of edited version , to illustrate possible toning down? Have to go now and feed daughter . Will wait til see your joint version first thingtomorrow - rest assured, that am entirely with you on this and still appalled by the MM stuff - but keeping your distance and calm stance is still urged. all the best to all any objections if I talk to Nature tomorrow?

What if were to eliminate the discussion of all the other technical details (and just say they exist), and state more nicely that these series were effectively censored by their substitutions, and that by removing those series which they censored, I get a similar result, with a dismal RE.

And most people would keep the RE of 0.42 over the RE of -6, right? So this would make that point. I think we also need to say something about the process, etc. (the intro was based on something that Malcolm/Ray had originally crafted).

Thoughts, comments? Thanks,


I'm thinking of a note saying basically this, and attaching this figure. Could everybody sign on to something like this?

Thanks for all your help,

Ray et al

I agree with this idea in principle . Whatever scientific differences and fascination with the nuances of techniques we may /may not share, this whole process represents the most despicable example of slander and down right deliberate perversion of the scientific process , and bias (unverified) work being used to influence public perception and due political process. It is , however, essential that you (we) do not get caught up in the frenzy that these people are trying to generate, and that will more than likely lead to error on our part or some premature remarks that we might regret. I do think the statement re Mike's results needs making , but only after it can be based on repeated work and in full collaboration of us all. I am happy to push Tim to take the lead and collaborate in this - and I feel we could get sanction very quickly from the DEFRA if needed. BUT this must be done calmly , and in the meantime a restrained statement but out saying we have full confidence in Mike's objectivity and independence - which we can not say of the sceptics. In fact I am moved tomorrow to contact Nature and urge them to do an editorial on this . The political machinations in Washington should NOT dictate the agenda or scheduling of the work - but some cool statement can be made saying we believe the "prats have really fucked up someway" - and that the premature publication of their paper is reprehensible . Much of the detail in Mikes response though is not sensible (sorry Mike) and is rising to their bate.

Tim, Phil, Keef:

I suggest a way out of this mess. Because of the complexity of the arguments involved, to an uniformed observer it all might be viewed as just scientific nit-picking by "for" and "against" global warming proponents. However, if an "independent group" such as you guys at CRU could make a statement as to whether the M&M effort is truly an "audit", and if they did it right, I think that would go a long way to defusing the issue.

It's clear from the figure that Reno Knuti sent yesterday that something pretty whacky happened in their analysis prior to ~AD1600, and this led Mike to figure out the problem. See: [1]file:///c:/eudora/attach/nh_temp_rec.jpg

If you are willing, a quick and forceful statement from The Distinguished CRU Boys would help quash further arguments, although here, at least, it is already quite out of control.....yesterday in the US Senate the debate opened on the McCain-Lieberman bill to control CO2 emissions from power plants. Sen Inhofe stood up & showed the M & M figure and stated that Mann et al--& the IPCC assessment --was now disproven and so there was no reason to control CO2 emissions.....I wonder how many times a "scientific" paper gets reported on in the Senate 3 days after it is published....


Interesting that the yanks view the CRU as an "independent group", and want their help in squashing Steve McIntyre.

Also interesting that the seek sanction from DEFRA, when according to an answer to a question in parliament, they responded that they got no money from DEFRA. Why seek sanction from DEFRA then?
