Good morning, cackling fools!
Let's examine a fundamental point that is being missed by you deniers:
This guess (OP topic), wrong or right, has no real bearing on AGW theory. In a surprise to exactly nobody, you deniers don't really take the time to think through any of this and to attempt to understand what is actually being said and what it means.
To illustrate:
Evolutionary theory explains how we got the diversity of species from one common ancestor.
Now, say a biology researcher takes a guess that a certain species shared a common ancestor with another species, withwith common ancestor being constrained to a particular place and time in history. But, oopsie, upon researching his guess and gathering evidence, he discovers that these two species could not have shared a common ancestor within this particular timeframe and location.
Is this a "failure of evolutionary theory"? Does this upend evolutionary theory? Of course, the correct answer is "no" to both questions.
In fact, this is not a "failure" of science at all, but rather a victory, as the evidence wins over hopes and feelings.
So, in short, the thread title is a lie, the OP is misguided at best (and a liar, at worst), and this is thread is just one big, incestual family reunion of a bunch of happily dumb, cackling deniers.
Have a nice day!
