Only thing I would comment on is why would I want to listen to a geologist? It is almost like going to a car mechanic for medical advice...

Now granted he may know a bit about warming trends in the past from geology (not much though, those trends tend not to show up very well unless they change the geology in an area (like a glacier for example), most of what we know comes from the fossil record instead which is pretty separate from geology). But he is way outside his field of expertise when it comes to current environmental patterns and changes, and determining the causes of those changes.

That he has papers and books out on the subject doesn't matter, like most books and papers out there, they probably are not worth the paper they are printed on.

So why should I listen to him?
