Here's an interesting interview with British documentary maker Martin Durkin. He can't seem to find much evidence to support man-made global warming.

The climate has always changed. Climate change is nothing new. The question of whether we are having anything to do about it, of course, rests on the CO2 question. [...]

Temperature has risen, slightly, falteringly and gradually for about 150 years or so (even ‘warmer’ scientists can’t claim that this started because of us). The period before this rise has long been known as a ‘Little Ice Age’, from which we are evidently making a welcome recovery. We only started pumping out CO2 properly in the postwar boom, but what did temperatures do? In the postwar period they fell, till about the mid-70s. Then they went up again (just like they did at the beginning of the 20th Century, and then for the past ten years they’ve more or less flat-lined, decreasing slightly. Where is the evidence that humans are changing the climate? This is nothing but prejudice. It is not serious science.

Doesn't Durkin know Al Gore "settled" this science long ago? Durkin also has some ideas as to what motivates many in the "green community"

It is transparently obvious that the greens sit squarely in the tradition of Romanticism. Like the romantics, they hate industry, love nature, idealise peasant life, they think capitalism is wicked, they think people in modern society lead depraved shallow lives and have forgotten the true value of things, they don’t like cars or supermarkets or lots of proles taking cheap long-haul holidays, etc, etc. [...]

Romanticism is in essence anti-Capitalist. Not in the sense of traditional Marxism. The Marxists wanted to go forwards not backwards. They wanted to build bigger factories than the capitalists, not folksy medieval craft workshops. No. Romanticism was a kind of reactionary anti-capitalism. And it was the ideology and aesthetic worldview of those people who lost most, or gained least from capitalism. I think it’s the same today. In Europe, the toffs (Prince Charles and his gang) are green because they have lost their position in society. The intellectuals – teachers, lecturers, scientists are green because they don’t have the status they used to. (Not long ago, a professor would have been someone important, had a big house, maids etc). These days, plumbers make more money.


It’s not easy to explain this properly in a few lines, but this I think is the real basis for all those anti-modern green prejudices.

I had always equated the green movement with Marxism, but Durkin's analysis makes some sense. Read the whole interview, it's very compelling.
