State of fear

In the book Is Kenner character fleshed out to where he's an actual character (i.e. physical, mutual description, nearly life like) or is he more like the voice of Micheal Crichton? What is the signifinance of you response?
In the book he is given physical characteristics: horned glasses, middle aged, and balding hair.
I am not sure if he represents the voice of Micheal Crichton because I do not know enough about Micheal to say one way or the other. Unless at the end of the book Micheal gives a impression on his feelings, I have around 50 more pages to read. The book gives Kenner a since of importance and being a very intillegent. He always has an answer for the so called fears or concerns people are campaigning about. He is not convinced that global warming is a issue that warrants so much concern. He feel that it is just used as a tool to make people scared and give lots of money. He seems to be connected just about everywhere. He also knows what the opponents are up to, like bombs in the snow, creating lightening storms. Now they are flying to where they are creating a hurricane.
