Science is not a set of dogmas, and it is not a pronouncement by a committee. It is a method. Richard Feynman, perhaps the world’s most eminent physicist, put it this way:
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 the experiment, it is wrong. In that simple statement 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.The catastrophic anthropogenic global warming theory is based entirely on models, which are programmed by their creators to predict disaster. But we know for a fact that the models are wrong, because they disagree with reality. When the facts collide with a theory, the facts win.
At Watts Up With That?, Don Easterbrook applies the scientific method to the recently-produced National Climate Assessment (NCA). The NCA predicts all kinds of awful consequences from a hypothetical rise in temperature that is based exclusively on models, not on observation. Easterbrook finds that the NCA fails the test of reality. Here are a few examples. ......."
