My guest IN THE STUDIO today is John Cook, astrophyscist, web developer, and founder of Skeptical Science, an absolutely brilliant resource for anyone needing to refute the common climate change denialist.

We talk about what motivates climat change denialists (and the difference between being a SKEPTIC and a DENIALIST) and some of the refutations of their most common arguments.
