A grab-bag of replies before I get back to work. (Yes, on a Sunday; sigh.) - The notion that science can be "proved" is a mistaken one. - I don't think there's much question by anyone that there has been measurable warming this century; so that part of your question is answered. ;) - How much of the data is really "hidden"? There certainly hasn't been a effort to widely distribute it from a central source (until lately: http://www.realclimate.org/index.php/data-sources/ http://www.realclimate.org/index.php/data-sources/), but that doesn't mean it was under lock and key either. Personally, I am biased in the other direction: I feel that it is likely that the extreme pressure and politics involved are forcing climate scientists to be over-conservative in their conclusions.
