Its all them atom bombs whats doing it. That is what the old dears used to say in the event of unusual weather when I was growing up in the back streets of Tottenham in north London. There is something deep in the human psyche that requires a cause to be identified for every effect. Presumably this has an evolutionary advantage: man the toolmaker was able to turn abstract concepts, such as consequence and purpose, to his benefit. Mind you, even in those far off innocent days they did not fly into a panic, as we did in 2006, over a mild October. They just enjoyed it. They even have a term for itIndian Summer. What a fine example of ratchet reporting we saw in 2006, with almost every British newspaper showing horror pictures of late flowering gardens. Yet they studiously ignored the fact that 2006 was a year without a spring, when the tree blossom was a month late. That instinct has been a gift for the shamans of each age, ours no less than those that went before. Now carbon, the very stuff of life, has been cast in the role of original sin and its dioxideabsolutely essential to the existence of life on Earthcondemned as a pollutant. Just as deviation from the strictures of the gods resulted in calamities such as floods and earthquakes in the past, so our new godless religion decrees that every disaster and minor discomfort arises from our engagement in industry, progress and the pursuit of well-being... From allergies to maple syrup shortages to yellow fever: apparently every contemporary ill is caused by climate change... What is it about humanity that provokes this addiction to scaremongering? In the seventies, when the scare was global cooling, there was still a residue of that scepticism that was the legacy of British philosophers. From the Bacons, through the likes of Locke, Hume and Russell, to the magnificent climax of Poppers statement of the principle of falsifiability, the scientific method was painfully established, only to be abandoned in a few short decades. The method was essentially sceptical, as Thomas Huxley put it: The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, scepticism is the highest of duties; blind faith the one unpardonable sin.
