The other day, as a favor, I posted a scientific article from a friend of mine, Dr H. Harrister, PhD, who conclusively showed that fitter people have larger carbon footprints…

I had the knife at my throat after reading a paper by Preti, Lentini, and Maugeri in the Journal of Affective Disorders (2007 (102), pp 19-25; thanks to Marc Morano for the link to World Climate Report where this work was originally reported). The study had me so depressed that I seriously thought of ending it all.

Before I tell you what the title of their paper is, take a look at these two pictures:

The first is the yearly mean temperature from 1974 to 2003 in Italy: perhaps a slight decrease to 1980-ish, increasing after that. The second pictures are the suicide rates for men (top) and women (bottom) over the same time period. Ignore the solid line on the suicide plots for a moment and answer this question: what do these two sets of numbers, temperature and suicide, have to do with one another?

If you answered “nothing,” then you are not qualified to be a peer-reviewed researcher in the all-important field of global warming risk research. By failing to see any correlation, you have proven yourself unimaginative and politically naive.

Crack researchers Preti and his pals, on the other hand, were able to look at this same data and proclaim nothing less than “Global warming possibly liked to an enhanced risk of suicide.” (Thanks to BufordP at FreeRepublic for the link to the on-line version of the paper.)

How did they do it, you ask? How, when the data look absolutely unrelated, were they able to show a concatenation? Simple: by cheating. I’m going to tell you how they did it later, but how—and why—they got away with it is another matter. It is the fact that they didn’t get caught which fills me with despair and gives rise to my suicidal thoughts.

Why were they allowed to publish? People—and journal editors are in that class—are evidently so hungry for a fright, so eager to learn that their worst fears of global warming are being realized, that they will accept nearly any evidence which corroborates this desire, even if this evidence is transparently ridiculous, as it is here. Every generation has its fads and fallacies, and the evil supposed to be caused by global warming is our fixation.

Below, is how they cheated. The subject is somewhat technical, so don’t bother unless you want particulars. I will go into some detail because it is important to understand just how bad something can be but still pass for “peer-reviewed scientific research.” Let me say first that if one of my students tried handing in a paper like Preti et alia’s, I’d gently ask, “Weren’t you listening to anything I said the entire semester!”
