Prof Jerome Ravetz of Oxford University has written a very well written piece over here which discusses Climategate with particular reference to his concept of Post Normal Science.
I enjoyed the read, but these are my comments that I posted on WUWT:

This is a well written piece, but it is easy to be seduced by the language. Personally, I find the concepts of “post normal science” quite disturbing. I have worked as a scientist and as a software developer for some 30 years. I have also undertaken a lot of endevours such as climbing in the Himalaya, paragliding, and kayaking. In all of these activities, there are often times when the “stakes are high” In these situations, we do not throw out our preconceived ideas. In all this areas, we develop processes where we can react to the high pressure demands of the task in hand with a clear and reasoned approach. When facing an impending storm at 6000m in the Gangotri mountains, believe me the last thing you need is a paradigm shift. In this sense, I do not understand why climate change “science” needs a paradigm shift, especially as there is no immediate signal that any drastic action is required
