We chatted a lot, since we stayed in a place without good Internet connection, and we didn't have other things to worry about during those few days.

Naturally we talked about AGW, since he is an ecologist.

What surprised me was that, in general, he agreed with the claims of AGW.

However, when I asked him several key aspects in details, his answers actually led to the opposite conclusions.

I didn't point out such inconsistency to him. But I felt that it's really not easy to keep one's mind clear and alert--even if he's a recognized scientist.
