[ExI] climategate again

I've been wondering about that. I haven't resolved the issue to my 
satisfaction yet, but here's a different view from yours:

On top of this, I've yet to adequately verify or refute claims that 
80% of the 0.6 C rise in global temps over the last century is 
actually due to highly dubious adjustments (a la CRU) to the raw 
data. For instance: not only ignoring the urban heat island effect, 
but adjusting it the opposite way from what makes sense. (That would 
be such a serious error that I have a hard time believing even the 
global catastrophists would do it.)

I'm feeling pretty lonely on this issue. Just about everyone on all 
sides of the issue seem to be very certain of what's going on. 
Despite considerable reading of clashing sources (or because of it), 
I remain highly unsure.
