I have always had a problem with the theory of human catalyst global warming. Not that the Earth is or is not getting hotter but that humans play a significant role in that effect. The main problem I have is that the reason that the theory is dependent on is not available for public scrutiny. Personally I never trust the comments of someone who says, “I have proved XXX, but I am only going to allow professionals to view my work; the public has no need.”
Well a couple of articles are starting to bring to light some of these kind of questions. This USAToday article points to a couple of researchers who reviewed the Global Warming data and came up with the opposite conclusion. The main difference is that they are opening their research to public review. The other article points out that the sun is actually giving off more heat in the last 20+ years or so.
Whatever the outcome of Global Warming research (or any research for that matter), its fundamentally important the public review be made available before we make public policy decisions on it. I have little problem with emission control laws; but only if its based on sound (i.e. publicly review-able) data.
