Sorry to jump in on this thread have been meaning to poke my head in here for some time but never get around to it. Also please note have not looked at the rest of this thread even, if I get a chance I will this weekend! (Honest)
What would convince me is absolute scientific data mapping the temp changes right from the industrial revolution. An explanation of why there has always been temp changes through out our planets life, and why this temp cycle/rise is any different from previous ones that humankind had no ability to effect or contribute to it.
I am not blinkered, and if I am wrong I have no qualms about admitting that. I don't dismiss anything out of hand no matter what I believe. Unfortunately I have come across absolutely no data yet to prove this theory is anything other than just that.
Yes the media have done this with GW, why try to report on a subject they have absolutely no understanding of? I am sorry but it really irritates me. For me its not about refusing to believe, you show my sufficient evidence then fine, its about being almost hoodwinked by the media with dodgy science!
Ps- the flat Earth society, you have to love them
