Here is a great explanation of Climategate for non-scientists.
I agree with the conclusion. This scandal, as big as it is, does not pertain to the science regarding CO2 in the atmosphere. While I disagree in important ways with the IPCC in that regard (I believe their estimates of the rate of warming associated with CO2 are overstated by a factor of 3 or 4), it is important to separate what is, and is not, touched by Climategate.
The people implicated in this scandal were involved in reconstructing past climate conditions, specifically The Hockey Stick which played a part in Al Gore’s movie, “An Inconvenient Truth.”
