The climategate letters, programs, and datafiles show a systematic and repetitious pattern of hiding and falsifying inconvenient data, cherry picking, self deception, and replacing peer review with theological review of the holy synod. It is worth examining particular incidents from this sorry story in detail.
When considering one particular such incident, you should keep in mind that each such incident is not an isolated bad apple. Rather, the climate gate emails and data reveal that it is all like this, every paper, every publication, every claim. Every single climate warming paper, every single piece of climate warming evidence, every graph. Official science is not science, but theology, theology concocted to impose on us a theocratic state, which state will deny us the ability to make our living in an ‘unsustainable’ way, ‘unsustainable’, being code for impious, just as ‘legitimate peer review’ (scare quotes in original email) is code for illegitimate peer review, and ‘corrected’ data (scare quotes in original source code) is code for falsified data.
