This month marks the 15th anniversary of "Climategate" -- the release of thousands of emails among climate scientists showing them behaving very badly. The scientists colluded, and still are colluding, to create the perception of a manmade climate crisis, based on their preconceptions about the way the world works, backed by computer model projections -- computer models they helped build, inputting their assumptions about what affects global temperatures, an instance of confirmation bias, circular reasoning, or both. By contrast, real-world experience, demonstrated in measured data and trends, shows no crisis has occurred, despite repeated predictions of tipping points and specific terrible events made by climate scolds, none of which have come to pass.
