We should not be surprised that it is conservatives who have their heads down in the sand refusing to believe that the earth is gradually warming due to the carbon dioxide and other greenhouse gases we continue to pump into the atmosphere. As I wrote in a blog post I called "Global Warming Deniers" (http://www.cajunscomments.com/global-warming-deniers/), conservatives have a record throughout history of disputing new scientific discoveries which threatened their belief systems and/or their grips on power.
