The Nonsense of Global Warming

"It's global warming, of course." That's the Green's [= global warming extremist's] stock response to anything weather-related. Too much sun? "Global warming." Too little sun? "Global warming." Drought? "Global warming." Floods? "Global warming." Freezing cold? "Global warming."

I wish the great philosopher Sir Karl Popper were alive to denounce the unscientific nature of global warming. He was a student when Albert Einstein's General Theory of Relativity was first published and then successfully tested. Einstein said that for his theory to be valid it would have to pass three tests. "if," Einstein wrote to British scientist Sir Arthur Eddington, "it were proved that this effect does not exist in nature, then the whole theory would have to be abandoned."

To Popper, this was a true scientific approach. "What impressed me most," he wrote, "was Einstein's own clear statement that he would regard his theory as untenable if it should fail in certain tests." In contrast, Popper pointed out, there were pseudo-scientists, such as Karl Marx and Sigmund Freud. Marx claimed to be constructing a theory of scientific materialism based on scientific history and economic science. "Science" and "scientific" were words Marx used constantly. Far from formulating his theory with a high degree of scientific content and encouraging empirical testing and refutation, Marx made it vague and general. When evidence turned up that appeared to refute his theory, the theory was modified to accommodate the new evidence [rather than abandoning it as false]. It's no wonder that when communist regimes applied Marxism it proved a costly failure.

Freud's theories were also nonspecific, and he, too, was willing to adjust them to take in new science. We now know that many of Freud's central ideas have no basis in biology. They were formulated before Mendel's Laws were widely known and accepted and before the chromosomal theory of inheritance, the recognition of inborn metabolic errors, the existence of hormones and the mechanism of nervous impulse were known. As the scientist Sir Peter Medawar put it, Freud's psychoanalysis is akin to mesmerism and phrenology; it contains isolated nuggets of truth, but the general theory as a whole is false.

The idea that human beings have changed and are changing the basic climate system of the Earth through their industrial activities and burning of fossil fuels—the essence of the Green's theory of global warming— has about as much basis in science as Marxism and Freudianism. Global warming, like Marxism, is a political theory of actions, demanding compliance with its rules.

Those who buy in to global warming wish to drastically curb human economic and industrial activities, regardless of the consequences for people, especially the poor. If the theory's conclusions are accepted and agreed upon, the destructive results will be felt most severely in those states that adhere to the rule of law and will observe restrictions most faithfully...

Thanks to heavy government subsidies, many farmers switched from growing food to biofuel crops—perhaps the most expensive form of energy ever devised. The result has been a world shortage of food, with near starvation in some places, and a rise in the cost of food for everyone...

Marxism, Freudianism, global warming. These are proof—of which history offers so many examples—that people can be suckers on a grand scale. To their fanatical followers they are a substitute for religion. Global warming, in particular, is a creed, a faith, a dogma that has little to do with science. If people are in need of religion, why don't they just turn to the genuine article?
