It’s been since the climategate emails came out that I read any of them and I didn’t read all of them at that time either, but, one thing I remember being kind of surprised about was the seeming almost complete lack of control over data integrity.

They were basically just emailing zip files back and forth to each other was what I remember. No central repository. No software enforced versioning system. No checksums. No software source control.

I think if Mann went to a court of law to prove AGW it’d be thrown out due to improper handling of the evidence - ie. the data.

Please note I’m only commenting on the apparent lack of rudimentary controls that programmers and others use to ensure and verify data integrity, not on anything else.
