There is a really good piece up at the Yale Forum on Climate Change & The Media that looks at the top five most prominent issues raised in "ClimateGate", analyzes the relevant emails in context, and finds some concerns but not much wrong--with the notable exception of the suggestion that emails subject to a Freedom of Information request be deleted. The article's author, Zeke Hausfather, concludes:
It is unfortunate, if perhaps not surprising, that the quotes from the e-mails that have gotten the most publicity from skeptics and in some media strongly distort the views and actions of the scientists in question, contributing to a perception of collusion to manipulate the climate data itself.
Nothing contained in the e-mails, however, suggests that global temperature records are particularly inaccurate or, worse, that they have been manipulated to show greater warming. The certainly troubling conduct exposed in some of the e-mails has little bearing on the fundamental science that strongly indicates that the world is warming and that anthropogenic emissions of greenhouse gases are the primary cause.
You should read the whole piece
, for it clearly and soberly shows just how much this has been blown out of proportion.
