William Happer writes in the Wall Street Journal, Global Warming Models Are Wrong Again, 3/26/12
It is easy to be confused about climate, because we are constantly being warned about the horrible things that will happen or are already happening as a result of mankind’s use of fossil fuels. But these ominous predictions are based on computer models. It is important to distinguish between what the climate is actually doing and what computer models predict. The observed response of the climate to more CO2 is not in good agreement with model predictions.
We need high-quality climate science because of the importance of climate to mankind. But we should also remember the description of how science works by the late, great physicist, Richard Feynman:
“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.”
At the risk of repeating what has been often written in this blog, the tone of the debate too often takes on the language of religious fanaticism rather than science. When a theory conflicts with facts the scientists adjust the theory, the ideologue tries to adjust reality. That is the cause of much of the tyranny caused by moral supremacists.
I am no scientists but there is a debate on this issue. Perhaps there is global warming, but it sure was a pretty weekend.
