I'm going through some of the email excerpts from this site and as a general thought I think a lot of it is taken out of context, and some of the lines just seem like the scientists are joking with each other. That said some of the emails are a bit more alarming.
1st email - youve all already mentioned. the fact that he wants to spread the code amongst trusted colleagues first, like poxpower, i think is a perfectly reasonable and acceptable thing to do. Its not like he's going to hide it from critics forever and leave them guessing as to how he got his results. Hes obviously going to have to empty his pockets at some point and show how he got there, as he himself says he is expecting loads of criticism in the future. He just cleaned up the code so he gets less shit criticisms
The 2nd email down in the link seems to be trying to take one line out of context from the rest of the lines in the actual e-mail.
"The Korttajarvi record was oriented in the reconstruction in the way that McIntyre said. I took a look at the original reference - the temperature proxy we looked at is x-ray density, which the author interprets to be inversely related to temperature. We had higher values as warmer in the reconstruction, so it looks to me like we got it wrong, unless we decided to reinterpret the record which I don't remember. Darrell, does this sound right to you?"
The argument in that link is that they are modifying data, which from reading it I disagree with completely. They state the author interpreted the 'temperature proxy' one way, and they may have interpreted another way. That certainly doesn't sound like modifying data to me but them choosing a different way of understanding it.
The 3rd one the excerpt only highlights a couple sentences that are apparently an acknowledgement of urban effect (even though the preceding line makes it sound like they have a different explanation "we probably need to say more on this"). It sounds like a lot has been cut out from the email before this excerpt to support the author's point.
The 4th one - you guys are having a field day already. This seems to be the biggest issue not just fo this thread but across the board. I think there have been reasonable explanations made which answer this issue by people who actually have a clue
The 5th email is quite worrying but the idea that their observing equipment is inadequate could potentially play against both sides of the global warming argument, especially if they anti GW are using the argument the data from 'mikes nature trick' shows cooling.
The 6th one, from reading the email the highlighted line "As we all know, this isn't about truth at all, its about plausibly deniable accusations." sounds to me like a throwaway sarcastic comment. It seems the robustness of something has come into question and they've already emphasised the point and already answered these issues from nay sayers and are getting annoyed. For that comment to be genuine makes no sense, to me anyway.
The 7th one has my favourite argument. The first highlighted line "Leave it to you to delete as appropriate!" does sound worrying but we don't really have a way of knowing what they're talking about. But "Don't any of you three tell anybody that the UK has a Freedom of Information Act ! " is obviously a joke but is being used as serious and as proof of withholding data.
The 8th email shows that they do have the ability to censor on the site, but is not proof that it is happening. It sounds like a logical thing to do to screen posts before posting them so that valid points don't get lost in a sea of piss. A person from the website has addressed this issue in a reply to a comment.
The 9th one I don't understand how it shows there is data being withheld.
The 10th one certainly is suspicious. but we don't really know what is being deleted because the excerpt doesn't include the whole email which would certainly give us a better idea.
To me the 11th email sounds the worst. It does actually look like the guy wants to change some data to suit an explanation. Granted he hasn't done it and is in the process of talking it through with the receiver, but to me that sounds sketchy cos the explanation should suit the data not the other way round.
The 12th email is another example of emphasising a line even when there is a perfectly reasonable solution in the same bloody email. The claim of withholding data is false as it says in the very sentence after the highlighted one. He's just making this mcintyre guy work to try and disprove him. And even if you still think the claim of withholding data is true, at least think about the reason behind it. Its not to hide anything, its to piss off mcintyre, as he is seemingly doing through constant hounding.
The 13th emails sounds all above board.
14th - date changing sounds dodgy and should be followed up.
15th - The 'withholding of data' claim is either false or out of their control. 1st point has no issues. 2nd point sounds like an issue similar to data protection or something. They've obviously had to pay for data for from some sources and possibly cannot send it on as it would be in breach of contract. 3rd point - Sounds like a solution to number 2, and sounds like the correct data would be getting sent in whole (just apparently it would annoy them).
16th - does sound like a genuine not telling the whole truth scenario.
All in all there are some questionable instances, and although I still side on the fact these are out of context and these people certainly haven't just made global warming up. Im going to keep an open eye for further developments
