The bottom line of politically correct thought on the matter—the thought that we must collectively do something drastic now to prevent climate change in the future—is so full of holes that it brings the overall sanity of mankind into question. For what it is worth, one possible theory is that mankind, or a fraction of it has become both over-educated and more delicate as a result of a massive increase of its wealth in recent times. It has managed to remove the beliefs of existing religions from its consideration—and now it misses them. As a replacement, it has manufactured a set of beliefs about climate change that can be used to guide and ultimately to control human behaviour. The beliefs are similar to those of the established religions in that they are more or less unprovable in any strict scientific sense.
