:I disagree with your characterization of Realclimate as "(a well respected climate blog run by scientists)." Realclimate is a PR blog, paid for by a PR organization Environmental Media Services that is run by scientists who are activists first and pseudoscientists second. They are pseudoscientists because they do not archive their data nor share data. Note the Hockey stick controversy and the fact Michael Mann knew his results were not robust without the bristlecone pine series and yet he never disclosed that fact. Steve McIntyre discovered the "BACKTO_1400-CENSORED" folder on Mann's ftp site. You can read about it here. Kyoto protocol based on flawed statistics The story is by Marcel Croc, translation by Angela den Tex, Natuurwetenschap & Techniek, February, 2005. Also, Realclimate censors questions it does not like so it can avoid questions it cannot answer. Just try to ask Michael Mann a question about his "BACKTO_1400-CENSORED" folder and see if it makes it onto the blog.   
 ::Note: The above comment was cut by Kim saying it was libelous.  I suppose he was referring to the comment about Michael Mann.  This is categorically untrue.  I provided a reliable source, the Dutch science magazine Natuurwetenschap & Techniek.  Raymond had raised the same issue on the BLP noticeboard but no one had a problem with it because this is a reliable source.
