Sounds like you have little or no faith in humanity. I won't even attempt to argue that point. Without believing there are some devoted humanitarians, nothing said will ever be believable. As for me, I do know a number of true scientists who have sacrificed much in an attempt to prove their points to the world. They will never be rich for doing it but their integrity has prevented them from being bought out by the corporations and politicians. They sincerely believe in the facts that have proved to them that global warming is being effected by man's actions and are continually striving to prove those beliefs.
