I followed every link you sent to me. I posted the very discussion about the paper you cited in the second link (wich left all the questions I listed in
http://www.internationalskeptics.com/forums/showpost.php?p=1463131&postcount=241 open) and I told you that that was the subject of discussion in Tim Lambert's site (since I didn't want to send you to climate-audit, wich has all the points raised in the refutation covered. I tought you won't go there. You even don't want to go to Lambert's site to read the discussion about the paper you sent me).
The main point is that, despite MBH claims , there was a Medioeval GW, wich almost trashes the idea of AGW.
I'm now in refutation phase. I made my mind about GW, and now I think that is not Anthropogenic. So I'll dedicate my efforts to read any other materials outside M&M and MBH wich try to demostrate that there is AGW. I guess we will find an answer pretty soon , because the contribution of Metane due to tropical forrest is starting to be investigated. It would completely change the way we understand the greenhouse effect if the findings are confirmed.
About the other links you sent to me, most of then talk about GW and how fast is that happening. Since I don't argue against GW, wich I think is real, you have no comment from me for most of your links.
You seem to think that the climate issue is easy to study. Is not. Scientists are divided about what is causing the current GW and the arguments are hard to find and harder to follow. There are tons of variables that should be taken into account in models and lots of considerations.
But there is a fact that has been ovelooked AFAICT: Many sources you cite says that GW is increasing a lot faster than the models predicted. The conclussion is, of course, that the models are WRONG wich is my main contention about the issue. A model which takes into account the effects of the principal greenhouse gas (H2) and the contribution of metane is yet to be developed.
Enought rant. If you have more material supporting AGW other than Mann's (and better, taking another variables into consideration) please post it here.
