Oh God, not the 97% thing again. 97% of climate scientists agree that there is a global warming trend and that human beings are likely the main cause? Meaning we are over 50% responsible? First, the warming is a whopping 0.8 degrees over the past 150 years, and a warming that has tapered off to essentially nothing in the last decade and a half. PRIOR to that revelation (around 50 years ago) we were in a cooling phase that was its own existential threat to humanity.
But that aside. John Cook is the driver behind that stupid statistic. But when his study was publicly challenged by economist David Friedman, one observer calculated that only 1.6 percent explicitly stated that man-made greenhouse gases caused at least 50 percent of global warming. Cook had created a category called “explicit endorsement without quantification”. That is, papers in which the author, by Cook’s own admission, did not say whether 1 percent or 50 percent or 100 percent of the warming was caused by man. He had also created a category called “implicit endorsement,” for papers that imply (but don’t say) that there is some man-made global warming and don’t quantify it. In other words, he created two categories that he labeled as endorsing a view that they most certainly didn’t.
So much more to say on this, but that’s enough.
