Scientists are natural sceptics-and we're also sceptical about debunking. Almost all of us on this blog, following Graham and others, believe in some form of catastrophism, but very few were worried on December 12. There are those on this board that are regarded as "truthers (911)," "birthers (Obama's birthplace)," or "deniers (global warming)," and some are all three. You would seem to believe that the first two have been debunked, but global warming denial is correct--with McKibben, Gore, Hansen, and others as doomsdayers or (false) alarmists.
There are also those on this board who believe in spirits, aliens from outer space, and unidentified flying objects. There are many who are discouraged with American political parties and Obama, some believeing that all governments are controlled by a few wealthy kingmakers--and I haven't even yet gotten to Giza and the pyramids. I'd urge a dose of caution in using debunking as an infallible tool for determining the "truth" of such claims.
A scientist looks at these issues from a probabalistic perspective, if studies can be carried out--or as unknowable The more evidence, the more something is true--but we can never say that anything is absolutely true--or false. I might not believe in alien encounters--until a little green man walks through the door. That wouldn't convicne you, tohough, would it? I may not be a truther, but I can still refuse to accept conventional explanations of 911--and see weaknesses in efforts to debunk. The world may not end tomorrow, but there are earthquakes, volcanoes, and weather pattern changes.
Some "doomsdayers" may be trying to sell something. Some may be mentally ill--like Vincent van Gogh.
Lurker does not participate in normal forum discourse, but he's out there...watching, reading every message. He is usually quite harmless, and more often than not his silence reflects a natural reticence rather than sinister motives. If a fight breaks out he will quietly observe to avoid revealing his position. Occasionally, however, some mysterious impulse drives him to de-lurk and attack. This totally unexpected assault is universally regarded as an ambush, and other Warriors will turn on him savagely. Lurker seldom sticks around to fight it out, however, and after a brief exchange, he once again slips out of sight. . . .
