What? No, I demonstrated that the way you're evaluating this is flawed. "They can't tell me exactly what the temperature will be tomorrow within a tenth of a degree so all of their evidence is useless." See, I would give you hard data but you'd just stick your head in the sand and claim that mathematics is voodoo.
