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 – 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 being man-made, and many have made it into 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.

I have a suggestion as to why large groups of people are supporting the athropogenic global warming theory, but it is one I read long ago by an author I sadly cannot remember and credit. Ask yourself where the largest environmental movements are, and where the most radical / violent environmentalists are. The answer is, roughly, the USA, Canada, England and Germany. All of these countries are, among other things, largely Protestant countries. Compare the environmental movement in these Protestant countries with the environmental movements in largely Catholic countries, such as Italy or Mexico. Compare it also with the environmental movements in Islamic countries. It seems that Christianity co-occurs with environmentalism more than with Islam, and more with Protestant Christianity than Catholicism. Protestant Christianity is heavy with stories of the original purity of humanity and our harmony with the Earth, but through our wickedness in taking on the powers of God we have brought about great suffering and destruction - including the any-day-now destruction of the entire Earth. Compare this to environmentalism, which is heavy with stories of the original purity of humanity and our harmony with the Earth, but through our wickedness in taking on the powers of God we have brought about great suffering and destruction - including the any-day-now destruction of the entire Earth. Environmentalism is in part an echo of Protestant Christianity, which was relegated to ceremonial reverence as the West adopted secular values. - Trevor Blake]
