A number of us on this forum are physicians or scientists. I spent 10 years in academic medicine and have published my share of articles in the scientific literature. While my area of expertise did not concern global warming, I am concerned about what I see as a loss of "objectivity" among the scientific community. Of course, the scientific community has never been as objective as the lay public would like to believe. One must remember that entire careers are riding on the concept of "global warming"...and scientists can become very protective of their turf. Furthermore, scientists are well aware of who funds their research and the specific biases of journal editors. It bothers me that some journals have actually taken a position on global warming...shouldn't they instead take a position on objective and quality research? Whether the government or private industry funds a research program, there is always an "expected" outcome. If you think otherwise, I have some beach front property in Tucson! No, I don't claim to be an expert, but we should be able to have an educated discussion on global warming without labeling people as ignorant or stupid. After all, I also welcomed (and still do) challenges to my scientific opinions and proposals.
There is a lot of data available to those who want to review it. Unfortunately, a lot is based on computer models and projections, sometimes not that apparent until you have read the entire article. And I tend to have less confidence in such results. I have seen Al Gore's film. I have also read Michael Crichton's book, State of Fear, which as a scientist I found far more informative and supported than Al Gore's film. For sure, Crichton has an opinion, but his book is well referenced, researched, and sourced. I found it very easy to find the articles he references and the graphs he illustrates. Some of this data is available on the NASA website.
From my take, it appears that we are experiencing an increase in global temperature, but no one really knows how much is natural or man-made. And we need more information...objective, critical research, subject to scrutiny by scientists in their fields of expertise. I fear that this will not happen, as it has become a political (don't question it!) hot potato.
Oh well, on to cars!
