Reiterating an important law of most academic studies
From an extensive statistical study published by Earth System Dynamics:
our rejection of AGW is not absolute; it might be a false positive, and we cannot rule out the possibility that recent global warming has an anthropogenic footprint. However, this possibility is very small, and is not statistically significant at conventional levels
If an academic study offends common sense, in all likelihood it is wrong. HT’s: WUWT, PL

From a referee:
Boldface mine.
My (lack of an) opinion doesn’t change: just because there might be nothing to worry about, I’m not willing to bet the biosphere; just because there might be a problem, I’m not willing to stifle the world economy and condemn billions of people to poverty.
I support continuing research, not just on the underlying facts but also on potential mitigation technologies.

Oops, somehow the blockquote feature bolded the whole passage quoted in my previous post. I meant to bold only “This is not the same as showing evidence against AGW”. Since a preview feature is not available at Dinocrat, I tested my comment in Blogger; it worked fine there.
