Well, Toddler, you are certainly one brain dead ass.
Simply put, every Scientific Society, every National Academy of Science, and every major University states that AGW is real, and a clear and present danger.
Of course, an ignoramous of a message board poster that presents zero evidence for his statements is supposed to convince us otherwise. LOL
And you're a brainless fool. Answer his question silly person. Why did they have to "hide the decline" then. C'mon MENSA BOY! Tell us!
