I doubt if this will have any affect on the GW thing at all. I mean, facts have been on our side of the debate throughout this entire argument, but they (the GW believers) have never allowed facts to get in the way of their presentation. And they (the GW believers) have been very effective in getting others on board in spite of the lack of factual data.
I just don’t see how this admission that the few “facts” they presented were just created out of thin air will sway anyone.
One key difference is that people like us can now respond forcefully with the facts of this case. In the past the alarmists controlled all the data; that is no longer so. I think this release has severely damaged the AGW cause.
