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."

The name of "science" is invoked by the left today, as it has been for more than two centuries. After all, Karl Marx's ideology was called "scientific socialism" in the 19th century. In the 18th century, Condorcet analogized his blueprint for a better society to engineering, and social engineering has been the agenda ever since.

Not all the advocates of "global warming" are on the left, of course. Crusades are not just for crusaders. There are always hangers-on who can turn the true believers' crusades into votes or money or at least notoriety.

Whether the globe really is warming is a question about facts -- and about where those facts are measured: on land, in the air or under the sea. There is no question that there is a "greenhouse" effect. Otherwise, half the planet would freeze every night when there is no sunlight falling on it.

There is also no question that the earth can warm or cool. It has done both at one time or another for thousands of years, even before there were SUVs. If there had never been any global warming before, we wouldn't be able to enjoy Yosemite Valley today for it was once buried under thousands of feet of ice.

Back in the 1970s, the environmental hysteria was about the dangers of a new ice age. This hysteria was spread by many of the same individuals and groups who are promoting today's hysteria about global warming.

It is not just the sky that is falling. Government money is falling on those who seek grants to study global warming and produce "solutions" for it. But that money is not as likely to fall on those skeptics in the scientific community who refuse to join the stampede.

Yes, Virginia, there are skeptics about global warming among scientists who study weather and climate. There are arguments both ways -- which is why so many in politics and in the media are so busy selling the notion that there is no argument.

If you heard both arguments, you might not be so willing to go along with those who are prepared to ruin the economy, sacrificing jobs and the national standard of living on the altar to the latest in an unending series of crusades, conducted by politicians and other people seeking to tell everyone else how to live.

What about all those scientists mentioned, cited or quoted by global warming crusaders?
