Karen, these comments by Sowell are right in line with the parody I made (see the picture) of that particular method of “argument”:

The political Left?s favorite argument is that there is no argument. Their current crusade is to turn ?global warming? into one of those things that supposedly no honest and decent person can disagree about, as they have already done with ?diversity? and ?open space.? …

In short, there has been a full court press to convince the public that ?everybody knows? that a catastrophic global warming looms over us, that human beings are the cause of it, and that the only solution is to turn more money and power over to the government to stop us from our dangerous ways of living.
