Over at “The End of Physics” we find a gem of a piece from this academic who says:
This one is particularly irritating because it’s essentially a silly circular argument. “Yes, we’ve warmed. However, we can’t tell, using a statistical model, if that warming was natural or not. Also, the only way we can tell if it is statistically significant is using a statistical model. Therefore we don’t know if it is natural or not.”
You’d like to think that people might eventually be embarrassed to have made such an argument.
On the positive side, he seems to have grasped the basic theory that one requires a model of “what is normal” in order to tell what is “abnormal”, but on the negative side, instead of admitting this means we do not have any certainty of human causation, he instead cannot bring himself to accept this, so turns the argument on its head to claim: “because we must be able to know it’s caused by mankind … it’s silly for skeptics to demand that we know what is normal …” before he jumps in like the big twit he is to say “of course global temperature is abnormal … I know because I’m a omnipotent academic and therefore the basic laws of physics and statistics must be wrong.
It’s a basic requirement that in order to know what is abnormal, we must first know what is normal.
