An excellent piece by Graham Strouts, looking at scepticism in general but with particular reference to Lomborg and Gore and the Horizon programme.
It seems to me that at some point the science ends and there is a cross-over into politics and ideology, and this is why Lomborg is important because he takes the conversation away from the purely technical issues of CO2 and emissions into what is the most cost-effective response. He could be wrong in his conclusions- I dont know. Pigliucci clearly thinks he is wrong, but his own ideology comes through most strikingly when he defends Gore against the charge of hypocrisy for his high-energy lifestyle while telling the rest of us we must cut back on everything to save the planet: “Gore pays for offsets to his travels in order to achieve a zero-carbon balance, just as he encourages the readers of An Inconvenient Truth to do.”
