In March, the Heartland Institute, which which says its "mission is to discover, develop, and promote free-market solutions to social and economic problems," will hold its second annual International Conference on Climate Change in New York. Speakers there, says the Institute’s website, will be "calling attention to new research that contradicts claims that Earth’s moderate warming during the 20th Century primarily was man-made and has reached crisis proportions."

He points out that the registration fee is $720 — but you get a 20 percent discount if you’ve signed the Oregon Institute of Science and Medicine’s Global Warming Petition, part of which reads: "There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth." "So, let me get this straight," writes Hickman. "If you say you believe in what they believe you will earn yourself a reward worth $144? Is this how climate change scepticism works? This must come as something of a let down for those that cling onto the notion that climate change scepticism offers a rare sanctuary for free thinking."
