Feynman: The Key to Science (1964)

“Now I’m going to discuss how we would look for a new law. In general, we look for a new law by the following process.

“First, we guess it (audience laughter), no, don’t laugh, that’s the truth. Then we compute the consequences of the guess, to see if this law we guess is right, to see what it would imply.

“Then we compare the computation results to nature, or we say compare to experiment or experience, compare it directly with observations to see if it works.

If it disagrees with experiment, it’s WRONG. In that simple statement is the key to science.

“It doesn’t make any difference how beautiful your guess is, it doesn’t matter how smart you are, or who made the guess, or what his name is…

“If it disagrees with experiment, it’s WRONG. That’s all there is to it.”

Climate models disagree with experiment, therefore they are wrong. Therefore, the hypothesis that our CO2 emissions cause significant global warming is wrong.

John Christy presented his data plots in his written testimony to the U.S. House Committee on Science, Space & Technology, on 2 Feb 2016. Some blogs that discuss his testimony are here and here.
