Factual data are crucial in real science. Einstein himself urged that his own theory of relativity not be accepted until it could be empirically verified. This verification came when scientists around the world observed an eclipse of the sun and discovered that light behaved as Einstein's theory said it would behave, however implausible that might have seemed beforehand.
Today, politicized "science" has too big a stake in the global warming hysteria to let the facts speak for themselves and let the chips fall where they may. Too many people-- in politics and in the media, as well as among those climate scientists who are promoting global warming hysteria-- let the raw data on which their calculations have been based fall into the "wrong hands."
People who talk about the corrupting influence of money seem to automatically assume that it is only private money that is corrupting. But, when governments have billions of dollars invested in the global warming crusade, massive programs underway and whole political careers at risk if that crusade gets undermined, do not expect the disinterested search for truth.
Among the intelligentsia, there have always been many who are ready to jump on virtually any bandwagon that will take them to the promised land, where the wise and noble few-- like themselves-- can take the rest of us poor dummies in hand and tell us how we had better change the way we live our lives.
No doubt some climate scientists honestly believe that global warming poses a threat. But other climate scientists honestly believe the opposite. That is why the raw data have had to be destroyed before the latter get their hands on it.
This is tragically the case as regards many other issues, besides global warming, where data are made available only to the true believers and kept out of the hands of those who think otherwise.
