Also in discussion of the biased AP report, Michael R. Fox, a retired nuclear scientist and chemistry professor from the University of Idaho says, "There is little evidence to believe that man-made carbon dioxide is causing temperature fluctuation. Other factors, including sun spots, solar winds, variations in the solar magnetic field and solar irradiation, could all be affecting temperature changes."

However, Ruddiman states that sun-spot activity could only explain one tenth to half of the temperature increase observed over the past century. <ref> Ruddiman (2000) Earth's Climate: Past and Future. W.H. Freeman and Company, New York</ref>

The natural orbital cycles which affect the amount of solar radiation reaching the earth's surface occur in cycles that at their shortest are at least 10,000 years long. As such these cycles alone are far too slow-acting to explain the temperature change observed in the past century and at best could explain only a tiny fraction of it. In fact, some of the cycles are at such a stage presently that they should be reducing the level of solar radiation reaching the earth and as such would be lowering temperatures.
