An excellent posting by Iain Murray which sums up the "Climategate" scandal. Excerpts:
Three Things You Absolutely Must Know About ClimategateMe, I'm an agnostic on this global warming thing. There's a lot of political theater going on around it, and that's unfortunate. But maybe it would be a good idea if the data used by these scientists were to be audited by an independent agency as part of "due diligence".
First, the scientists discuss manipulating data to get their preferred results.
Secondly, scientists on several occasions discussed methods of subverting the scientific peer review process to ensure that skeptical papers had no access to publication. [...] If you are saying on the one hand that you will not take notice of someone until they have been published while on the other you are working behind the scenes to stop any such publication, I would venture to suggest that you are not operating with any degree of bona fides either towards the media or the legitimate scientific process.
Finally, the scientists worked to circumvent the Freedom of Information process of the United Kingdom. [...] There appears to be a prima facie case that there was a conspiracy to prevent the release of information subject to FOI.
