From Peter Russell
The free iPhone /iPad application Skeptical Science contains a comprehensive set of counter-arguments to climate-deniers, one of the groups mentioned in your special on denial (15 May, p 35). The app gives detailed rebuttals to more than 100 different arguments a denier may use – very useful in the pub when you don’t have the scientific evidence to hand. It is unlikely to convert an obstinate denier, but may at least sow a seed of doubt, leaning them towards scepticism.
