To what extenet is Kenner the mouthpeice of Crichton?

In the book "State of Fear" the author uses a writing style where he expresses all the different opinions through different characters. Since Michael Crichton does not believe in global warming, it is safe to say that he is using Kenner to be his mouthpeice in the book. Crichton seems to express all of his opinions and supports them with facts through Kenner, and to make this book not completely dull he adds an opposing viewpoint from the character of Evan. I do believe that there is way too much talking from Kenner and not enough action. He has plenty of facts to support his theory and expresses them to try and get his point across but in reality he hasn't done much of anything but talk.
