(No don't bother with the Wiki. I doubt that will take us any further)
Agreed, it won't. Quoting Wiki is useful when arguing with a fugghead-- which you, sir, are not-- who doesn't know what the hell he's talking about but thinks he does. But generally, I think if someone has to resort to quoting the dictionary or a Wiki definition, then it's a pretty good indication the conversation/debate has ceased to be meaningful.
However, I think you're being disingenuous when you claim that the letter in question has no import because it's signed by "only" 16 scientists and top engineers. Scientists are generally a pretty contentious lot, and it's my impression that it's rather unusual to see that many experts in any field of science sign such a lengthy statement.
Now, if you could demonstrate that all or nearly all of the other 99+% climatologists in the entire world signed a letter stating "These guys are stuffed full of wild blueberry muffins!", then I'd be more impressed.
We are the 99%. A better world is possible.
