Paul Johnson, ex editor of The New Statesman...

...and author of the magnificent "Modern Times - A History of the World..." has this to say about the greens and climate change...
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...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 Greens' 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.
