‘Climate Modelling Nonsense’ (John Reid)

“The quasi-religious nature of AGW is evidenced by the rancour which is generated when people like me express scepticism about the theory. Scepticism is an essential part of science which has, until recently, been a “small-l liberal” pursuit in which the opinions of doubters were respected. Now we sceptics are called “deniers” and, by implication, lumped in with neo-Nazis who question the Holocaust. The accusation that we are somehow in the sway of the oil companies and similar big business interests is commonplace and indeed is the chief argument of non-scientist supporters of the AGW theory. This echoes the “work of the Devil” argument of fundamentalist Christians; it is a mental trick by which the faithful avoid facing the real issues.”

“A scientific theory is not tested merely by looking for confirmations but by conscientiously trying to “break” the theory, by trying to disprove it. The AGW theory is encapsulated in the IPCC assessment reports. The models discussed in these reports have not been tested in this way. These reports include sections on “Verification and Validation” but none on testing. “Verification” means that only data which support the theory are examined and data which do not support it are ignored. Indeed the authors of this section in the IPCC Third Assessment Report specifically dismiss the need for rigorous testing when they state:our evaluation process is not as clear cut as a simple search for ‘falsification’” (Section 8.2.2 on page 474). Effectively what they are saying is: proper scientific testing is too hard and we are not going to bother doing it.”
