I refuse to assume (contrary to the modern practice) that someone who disagrees with me is either stupid or ill-intentioned or both [OK, I did call people idiots here -- sorry, I was ranting]. Intelligent people of goodwill can disagree with each other, and the world would be a better place if more people embraced that simple notion.
Anyway, I won't blame lack of intelligence or bad motivations for the following statement from Bill Maher. He seems to be a smart guy who is honestly motivated by what he says motivates him. But this statement is just so ignorant and provably false that it must be the result of living in a very powerful echo chamber where no voices other than ones that agree with him are allowed.
HBO’s Bill Maher complained that comparing climate change skepticism to vaccine skepticism was unfair to vaccine skeptics before attacking GMOs on Friday’s “Real Time.”
“The analogy that I see all the time is that if you ask any questions [about vaccines], you are the same thing as a global warming denier. I think this is a very bad analogy, because I don’t think all science is alike. I think climate science is rather straightforward because you’re dealing with the earth, it’s a rock…climate scientists, from the very beginning, have pretty much said the same thing, and their predictions have pretty much come true. It’s atmospherics, and it’s geology, and chemistry. That’s not true of the medical industry. I mean, they’ve had to retract a million things because the human body is infinitely more mysterious” he stated.
Climate science is astoundingly complex with thousands or millions of variables interacting chaotically. Separating cause and effect is a nightmare, because controlled experiments are impossible. It is stupendously laughable that he could think this task somehow straightforward, or easier than running a double-blind medical study (By the way, this is one reason for the retractions in medicine vs. climate -- medical studies are straightforward enough they can be easily replicated... or not, and thus retracted. Proving cause and effect in climate is so hard that studies may be of low quality, but they are also hard to absolutely disprove).
It is funny of course that he would also say that all of climate scientists predictions have come true. Pretty much none have come true. They expected rapidly rising temperatures and they have in fact risen only modestly, if at all, over the last 20 years or so. They expected more hurricanes and there have been fewer. They called for more tornadoes and there have been fewer. The only reason any have been right at all is that climate scientists have separately forecasts opposite occurrences (e.g. more snow / less snow) so someone has to be right, though this state of affairs hardly argues for the certainty of climate predictions.
By the way, the assumption that Bill Maher is an intelligent person of goodwill who simply disagrees with me on things like climate and vaccines and GMO's is apparently not one he is willing to make himself about his critics. e.g.:
Weekly Standard Senior Writer John McCormack then pointed out that there are legitimate scientists, such as Dr. Richard Lindzen, who are skeptical of man-made climate change theories, but that there were no serious vaccine-skeptic professors, to which Maher rebutted “the ones who are skeptics [on climate change], usually are paid off by the oil industry.”
I will point out to you that the Left's positions on climate, vaccines, and GMO's have many things in common, as I wrote in a long article on evaluating risks here.
