The video, which attracted condemnation around the world this week, shows a teacher encouraging her young charges to follow the 10:10 campaign's plan to reduce carbon emissions. When she asks for a show of hands from those who want to join the campaign, all but two of the children thrust their hands in the air. "That's absolutely fine, your own choice," the teacher says, smiling. Then she presses a red button and the two little holdouts explode, their blood and gore spraying all over their classmates. The same scenario is repeated in a workplace and on a soccer ground where those reluctant to join the campaign are messily vaporised. This nasty ad wasn't the work of Chaser-style fringe comedians. This was a serious product of the environmental establishment, an organisation sponsored by Sony - until the company pulled out this week - and in partnership with the Guardian newspaper. Politicians, schools, and celebrities all over the world have joined 10:10. Even our very own Hugh Jackman has been photographed wearing a 10:10 promotional necklace. The video was scripted by Richard Curtis of Four Weddings and a Funeral fame, and was the brainchild of the UK's version of Michael Moore, Frannie Armstrong, director of The Age of Stupid. It was the considered message from the very heart of the green movement - stand in the way of our plans and we will eliminate you. It's green Darwinism, known in earlier times as The Final Solution. Frannie and friends removed the video from the 10:10 website when complaints started, but it was too late. She has let the cat out of the bag. Now we have the evidence that during the long silence after the twin blows last year of the Copenhagen climate summit and Climategate, green zealots had been busy plotting revenge. They flipped the switch in their brains that takes them down the blood-spattered path of totalitarian death so well-worn in the 20th century. Now we know - climate change alarmism is a death cult. We heard the message in its starkest form last month from the US Discovery Channel's suicide bomber James Lee, whose eco-manifesto demanded no more "filthy human children", before he was shot dead by police. And we heard it in the subtle endorsement by Father Frank Brennan when he defended a vote for the Greens during the last election. "On some policy issues, I daresay the Greens have a more Christian message than the major parties," Brennan wrote in rebuttal of Cardinal George Pell's rather better description of the Greens as "sweet camouflaged poison". But, whatever way you dress it up, the climate alarmist message ultimately can be boiled down to death. No surprise that the first big issue in the kinder, gentler new parliament for Brennan's pet Greens was euthanasia. It's where their heads are at. Killing people. And if you're not dead then they'll make you suffer. Already this winter we have had stories of people forced to huddle over hot water bottles and even sleep with cats to keep warm because they can't afford to keep paying soaring electricity bills. The pain inflicted is deliberate. You are intended to suffer. In this land blessed with abundant reserves of cheap coal-fired energy, your suffering is what environmentalists and policy makers call reducing demand. You are being forced to turn off the heater, pull out your electric plugs and bathe in lukewarm water in order to - ahem - stop climate change. Electricity consumers are being hit twice - first with doubled prices to pay for inefficient green power such as wind and solar and then to catch up on infrastructure investment neglected by sloppy state governments. Then there is Julia Gillard's looming unpromised carbon tax. If it is priced at between $20 and $50 a tonne, as the Energy Supply Association of Australia told the Business Spectator's Robert Gottliebsen, then power bills will double again. In other words, over the next four to five years your electricity bill will quadruple. Suck it up, because your pain is the aim of the new green paradigm. Yet the greater aim is not to change the planet's temperature because no one knows how to do that. For one thing, evidence used by alarmists to justify killing people and by the Government to justify a carbon tax is looking increasingly flimsy. As the brilliant Perth-based mathematician David Evans, who wrote the Government's carbon accounting program when he worked at the Australian Greenhouse Office (now the Department of Climate Change) told a climate seminar last week, the temperature record is based in part on suspect readings. At a seminar by the American climate sceptic think tank the Heartland Institute in Sydney on Friday, Evans displayed images of temperature measuring stations around the world, including in Melbourne and Sydney, which stand next to heat-generating air-conditioners, freeways and asphalt runways. Thermometers that might once have stood in paddocks are registering higher temperatures due to what's been built next to them, whether that's a brick building, wastewater reservoir, carpark or incinerator. These humble bits of technology in prosaic locations across the planet determine surface temperature trends, yet their readings have been influenced by the so-called urban heat island effect. Since the whistle was blown by American sceptic Anthony Watts, some have been eliminated. But, as Evans pointed out, their results remain in the temperature record. That is the record which has so alarmed climate zealots they think nothing of advocating the murder of people who don't agree with them. Eco-fanatics are no different to totalitarian ideologues through the ages. Evils such as Nazism don't arrive with devil's horns; they come in disguise - "sweet camouflaged poison". So we should thank Frannie and her 10:10 comrades for their vile ad. They naively removed the camouflage too soon.
