On the growing theme of Tory climate change denial and the various insiginificant intransigences of the climate science community, the Observer has published an exchange between its science editor, Robin McKie, and Benny Peiser, the Director of the Global Warming Policy Foundation. This organ, chaired by the loathsome Lord Lawson, is dedicated to climate change denial and the dissemination of pseudo-intellectual criticism of its social and economic consequences. The exchange is remarkable for the crushing blows landed by the Observer hack and the slippery dodging and avoidance of the denier. Its disappointing that there is no final response from Peiser as I would be interesting to know how his anti-scientific ideology survives his eminent failure to present any evidence to support his position, as requested by McKie. But then climate change denial isn't about evidence or proof or reasoned argument. It is a profoundly ideological position, as McKie observes, and not at all susceptible to enlightenment.
