In his recent lecture before The Global Warming Foundation in London, former Australian Prime Minister John Howard addresses the "sanctimonious tone" of many to whom global warming has become a "substitute religion." An overriding feature of the debate, he notes, is the constant attempt to intimidate policy makers into following the party line that "the science is settled," when it is not. Rather than try to limit growth, Howard said, economists need to recognize that the world will have up to 2.2 billion new middle class consumers by 2030, and we need to provide goods and services for this emergent class.
