A clash of epistemologies: why the debate on climate change is going nowhere.
A few weeks ago, someone barreled into the comment section of a post on climate change on the blog of the Italian Society of Chemistry (SCI) with a series of attacks against climate science and climate scientists. The ensuing clash was all in Italian but, if you follow the debate on climate, you know very well how these things go. The newcomer monopolized the discussion by repeating the usual legends; climate has always been changed, there has been no temperature increase during the past 15 years, there is no proof of the human effect on climate, and so on. And you can imagine how the scientists following the blog reacted. The discussion rapidly degenerated into assorted insults and personal smears, until the moderator closed the comments. That was way too late: the climate science denier emerged as the winner; while the scientists managed to give the impression of being both narrow-minded and sectarian.
It was a classic case of climate trolling, but with one difference. This time, the troll didn’t try to hide his identity (as trolls usually do); rather, he came with a name, an address, and a CV. He was Mr. Rinaldo Sorgenti, vice-president of the Italian Coal Industry Association (“Assocarboni“). Mr. Sorgenti’s exploits on the SCI blog give us a chance to understand what generates the kind of behavior that we define as “trolling.” So, I am willing to bet that Mr. Sorgenti is NOT a paid disinformer – as he was accused to be in the debate. In other words, he doesn’t deny climate science becausehe is on the payroll of Assocarboni (actually, he maintains that he gets no money for his position of vice-president, but I figure he gets at least a few perks from it). I would also say that not even the opposite holds true: Mr. Sorgenti is not the president of Assocarboni because he is a climate science denier. No, I would bet that denying climate science and being involved in the coal industry are two non-separate and non-separable elements of Mr. Sorgenti’s worldview. And this worldview has little or nothing to do with what we call science. Mr. Sorgenti is not a scientist, he doesn’t know how the scientific method works or, if he knows, he doesn’t believe it works or it is useful for anything. He uses the methods of debate commonly used in the political debate; a method of discussion that we can define as “rhetoric.”
