We have been through all this before, and Soren is absolutely correct in his assertion that we all believe what we are told about AGW, as a matter of trust, he would probably call that faith, but it is most definitely trust.
I am not a climate scientist, in fact I am not a scientist of any kind, and I cannot independently check any of the more pertinent facts in any concrete fashion, so I have to choose who is most likely to be giving me correct information, pretty much on trust.
I simply determine that choosing reputable expert scientists that work in reputable universities etc. may be a more credible source than the experts that denialists choose, from these "institutes" that pop up every two minutes in an old tractor shed, or disused office block, and peddle denialism, evangelism, and republicanism, all from the same desk.
If you go the tractor shed experts, you can buy nukeyullar falledout sheltas for yer backyard at da same time, and theys can include comforting bible verses to go with it.
Just a matter of who to believe.
Here is a link to source watch, and what they think of the oregon institute of science and medicine.
This very place has been cited by every denialist here as a credible source of information, yet they have the strange idea that actual scientists working in teaching universities, not farm sheds whose primary purpose seems to be to print misleading pamphlets.
