The Rules of Science

Nobel physicist Richard Feynman describes the rules of science:

“In general, we look for a new law by the following process. First, we guess it. Then we compute the consequences of the guess to see what would be implied if this law that we guessed is right. Then we compare the result of the computation to nature, with experiment or experience; compare it directly with observation to see if it works. If it disagrees with experiment it is wrong. It’s that simple statement that is the key to science. It does not make any difference how beautiful your guess is. It does not make any difference how smart you are, who made the guess, or what his name is---if it disagrees with experiment it is wrong.” Dr. Richard Feynman, “The Character of Natural Law”, The MIT Press, 1965, p. 156.

The heart of science then is to propose and test hypotheses by explaining observations, evidence, and data from the real world. Any hypothesis which can’t explain the observations, evidence, and data must be revised or dropped. Please note that this process doesn't involve creation of a consensus.

So, given that the AGW believers do not follow this process, then they must be using something other than science for their process.
