Climategate's Final Days

The Bad Astronomer writes "Climategate may be on its way out. An investigatory committee at Pennsylvania State University has formally cleared climate scientist Dr. Michael Mann of any scientific misconduct. Mann was central in the so-called Climategate scandal, where illegally leaked emails were purported to indicate examples of scientists trying to cover up any lack of global warming in their data. This finding by the committee (PDF) is another in a series of independent investigations that have all concluded that no misconduct has occurred."

These 'debates' end basically when the people who are used to profiting off the old ways die, and new stakeholders have the opportunity to recast their position in a new light. For instance, cigarette smoking was known to cause cancer in the late 1800's. It was relatively well established by the 1950's. The only reason the debate went on another generation or two was to give the corporations time to restructure the business model. Now smoking is bad, and some people still choose to do it.

Go further back to the way blood circulates in the heart. In 1533 Michael Servetus published a paper saying the heart pumped the blood, as opposed to previous western belief that blood flowed like the tides, which some religious people put mythical significance to, and made part of their superstitions. If blood was pumped, then it would in some way continue to assert the superiority of science in furthering the human quality of life. By the early to mid 1600's William Harvery showed that the heart pumped blood. Here is the interesting debate. In the very early years of the Common Era, many philosophers though that the heart had an active role in pumping blood, but if you read the history, it seems like there never any consensus prior to Harvey, and that the tide theory was a valid conjecture.

The point is that as advance as we think we are, we are only a few hundred years out of the supertitious muck in which we tortured and drowned little girls to prove they were not witches. In which we would not wash our hands to save children. Some us may see it as 500 years since Galileo saved us from the myths, but in practical terms it has not been nearly that long.
