Thomas Sowell usually writes a well-reasoned article, but his recent piece on climate change never mentions carbon dioxide, which is probably the most contentious element of the climate-change debate.
Most climate scientists agree that we are in a warming period. The key questions are how much warming and what is the cause. Climate scientists, sponsored by the United Nations, believe that man-made carbon dioxide is the cause of warming and claim to have proven it in their reports. Other climate scientists disagree and believe that carbon dioxide is partially responsible for climate warming but that nature is the primary cause.
The Sowell article refers to a 2007 book by Singer and Avery on climate warming. One of the authors is probably S. Fred Singer, who edited a 2008 report entitled "Nature, Not Human Activity Rules the Climate."
It does an excellent job of refuting the claims made by the United Nations' sponsored scientists. Why hasn't this report and its conclusions received more attention in the press?
