Those are anything but stupid questions. But the answer to them can be summed up in two words, the two constants in all of human history ... Money and Power. This has nothing to do with science, the climate, or the environment. It’s money taken from the advanced and productive and sent to the pockets of third world thug chieftains, with Al Gore and his ilk managing the transfer and taking their cut. And the power to coerce and control humanity at the most basic level of survival.
Making raw data available is slowly becoming a requirement in the biological sciences, in part a response to overstatement of data, outright fraud, and over interpretation of findings. Scientists have a responsibility to question their own results, and to be committed to finding the truth - wherever it leads. One problem with this is that if the truth runs contrary to the ‘desired’ truth, it will be difficult to publish, and it could end your career.
