Rational argument, rhetorical argument, argument from fear and then millenarianism

Independent of the the underlying truth about anthropogenic global warming, a separate debate, it is yet another example of some human fundamental tendency towards millenarianism.

If you cannot convince people through evidence of some need to do something, if you cannot persuade them to voluntarily do something, if you cannot scare people into doing something, then perhaps millenarianism is the last resort. Rational argument, rhetorical argument, argument from fear and then millenarianism.

The bigger the change, the more the risks, the smaller the anticipated benefit from the change, the more likely millenarianism, a quasi religious belief, is likely to dominate the argument.

Brought to mind by Wrong Again: 50 Years of Failed Eco-pocalyptic Predictions by Myron Ebell and Steven J. Milloy. The article is actually a compilation of the work of Tony Heller where he has collected and documented the ebbing and flowing of apocalyptic climate forecasts over the past fifty years, the anticipated ice ages, global desiccations, the acidification of oceans, the loss of atmosphere.

The Sagan Standard requires that
Extraordinary claims require extraordinary evidence.
It is not a particularly compelling standard. Proof is proof whether deemed extraordinary or not. But it does capture a folk wisdom that acknowledges proof is rarely self-evident and the greater the deviation from orthodox knowledge, the more compelling needs to be the evidence. That in an epistemic world where knowledge is accumulated over time, it should be anticipated that the unsetting of precedent knowledge will only occur with increasing rarity. It can occur, and does occur but the Sagan Standard cautions against wild oscillations and faddishness.

Again, the point is not that there is debate about AGW. The point is that we are accustomed to millenarian arguments which do not pan out. If you are going to rely on millenarian arguments, that is the hurdle you have to overcome.
