CARGO CULT SCIENCE, by Richard Feynman, was presented at Caltech commencement in 1974. In it he defined Cargo Cult Sciences as theories that don't work, and science that isn't science.
What are Cargo Cult Sciences missing? Scientific integrity, a principle of scientific thought that corresponds to utter honesty; leaning over backwards. For example, in an experiment you should report everything that you think might make it invalid; not only what you think is right about it: other causes that could possibly explain your results; and things you thought of that you've eliminated by some other experiment, and how they worked--to make sure the other fellow can tell they have been eliminated.
AGW has become – probably always has been – a Cargo Cult Science. Examples of past warmer periods have been ignored or dismissed. Recent periods of cooling during heightened levels of atmospheric CO2 have been mated to strained explanations involving aerosols, etc. Recent low levels of Arctic ice create panic even though lower Arctic ice was previously reported – 1922 for just one example. AGW links were forged to Katrina, Midwestern tornados, Himalayan glaciers, Amazon rain forests, African agriculture, Mount Kilimanjaro ice cap, Bangladesh sea level, without mention that there were sounder scientific explanations for these anomalies.
And these are anomalies only in light of ignorance of climate history.
Like the true Cargo Cult believers, the AGW true believers gather in worshipful expectancy of catastrophes that will never come, while practicing rituals that do nothing to alter the direction of natural climate change.
