The letter itself is probably not good journalism, but together with other documents including the film, it gives the reader insight into the big arguments about global warming. Neither side can be proud of their handling of facts. Those promoting global warming are equally irresponsible to ignore the many facts that contradict their position. I'm a part of the Conservative Forum of Silicon Valley. You might be interested to know that the Conservative Forum has had several interactions with the San Jose Mercury News. Their news page editor has flatly said that the debate is over and she would not run another article that takes any exception to the global warming "facts". The editorial page editor said basically the same thing, though he would allow Letters to the Editor. (It's hard to make much of a point in 100 words.) We were able to submit and get published one article in the "other" opinion category. A week later, they had found another story (one of the authors was a biggie in the Sierra Club) to debunk ours. Nobody in the media can be very proud of their efforts to educate the population.
