Global Warming a Hoax?

Yes, photographers actually do talk about something other than cameras and pixels. The UN's IPCC bureaucrats have issued a summary document that declares they're 90% certain mankind has really screwed things up, but for some strange reason, the full report that's still in the works (produced by real scientists, which, BTW, backtracks on earlier claims) must conform to the so-called summary, not the other way around. Is that legit? What do you think?
