For a public figure, Mr. Gore has been strangely reluctant to answer questions or debate the more controversial parts of his work. But over the weekend, he deigned to take a few questions during a meeting of the Society of Environmental Journalists in Madison, Wisconsin.
Irish documentary filmmaker Phelim McAleer was in the line. A former Financial Times journalist, his new film, "Not Evil, Just Wrong," is a direct refutation of Mr. Gore's thesis and warns that rushing to judgment in combating climate change would threaten the world's poor. When his turn came, Mr. McAleer asked Mr. Gore about a court case in Britain in which a parent had objected to "An Inconvenient Truth" being shown to British schoolchildren because it was largely propaganda, not science.
