“ Although the world’s climate is on a warming trend, there is zero evidence that the rise in carbon dioxide levels has anthropogenic origins. For daring to say this I have been treated as if I have committed intellectual blasphemy. In magazine articles and essays I have described in fairly considerable detail, with input from the scientist Martin Hertzberg, that you can account for the current warming by a number of well-known factors having to do with the elliptical course of the Earth in its relationship to the sun, the axis of the Earth in the current period, and possibly the influence of solar flares. There have been similar warming cycles in the past, such as the Medieval Warming Period, when the warming levels were considerably higher than they are now. Yet from left to right, the warming that is occurring today is taken as man-made, and many have made this opinion the central plank of their political campaigns. For reasons I find very hard to fathom, the environmental left movement has bought very heavily into the fantasy about anthropogenic global warming and the fantasy that humans can prevent or turn back the warming cycle. ”
