In the ever evolving scam of anthropogenic global warming (now called "climate change" due to an absence of global warming), alarmists attack the opinions of any scientist who is not specifically a "climatologist." This is a recurrent theme in alarmist propaganda as to why any dissenting scientist has no credibility.
So the Petition Project, which documents the dissent of over 30,000 scientists (over 9,000 of whom are PhD's), is meaningless...because physics, biology, chemistry, and even meteorology are not "climate change science" and therefore these scientists' opinions hold no weight.
This is undoubtedly the chief logical fallacy pushed by the warmists, i.e. an appeal to authority. If some guy with a degree in "climatology" says man made global warming is happening on a large scale, than by god, it is and you can't possibly disagree. Here's why that is B.S.: if someone has a higher degree in math, and they say "2 + 2 = 5", you must accept what they say, because they have the degree and you don't. This is especially true where the mathematician's conclusions are "peer reviewed." That means another mathematician, who is also receiving big bucks from the government to arrive at the desired conclusion, has reviewed your work. Bingo! 2 + 2 = 5.
A climatologist is basically anyone with a degree in any number of sciences, who has used computer modeling to predict the weather or who has studied past weather patterns. Big whoopee. Here is an article from the Examiner. Note: it is four years old and since it was published, a number of "climatology" degree programs have been cobbled together by various universities. However, it is still of value in spiking the warmist logical fallacy of "appeal to authority."
