Neither Tyler nor Robin think that Climategate tells us much about climate science.  Robin says that “it’s news about academia, not climate”:

[T]this behavior has long been typical when academics form competing
groups, whether the public hears about such groups or not.  If you knew
how academia worked, this news would not surprise you nor change your
opinions on global warming.

I say it’s news about both.  If you previously thought that climate science was not very politicized, you should change your mind – and discount mainstream research accordingly.

P.S. Contrary to Steve the comments, “consensus science” is perfectly reasonable as a presumption.  It simply isn’t feasible for laymen to personally evaluate scientific research, and it isn’t reasonable to ignore evidence that you haven’t or can’t personally evaluate.
