The reason is simple: the negative feedback in the economic and political systems will prevent truly drastic measures from going into effect, or lasting. Furthermore, the free-riders (like China) will destroy any remaining political argument.

Climate alarmism is a luxury of those who can afford luxuries. It is death to the poorest of the poor, and not very interesting to most people on earth, who have more direct threats to deal with.

Unfortunately, as the DDT ban shows, if only poor people are dying for the cause of environmental correctness, it doesn’t matter to the alarmists – they don’t have to worry about Malaria in San Francisco or New York City.

The computer models cranked out by the stats geeks and their computer code will have caused the public to lose respect for the scientists who actually do real science.

If the “true believers” of this hysteria achieve their goal of reducing economic growth in this so-called greedy selfish evil empire of ours to “save the planet,” we will have significant increased poverty in the U.S. which will then increase calls for the strong central state, i.e. socialism… the excuse being: “capitalism has failed.” In other words, the politicians will theoretically correct with their right hand, problems caused by their left hand. The trick in doing this is to make sure somebody else gets the blame.

It has always been so.

Though it seems far unlikelier that Point 4 is true if Point 3 isn’t.
