In a May issue of Nature, evidence about falling global temperatures forced German climatologists to conclude that the transformation of our planet into a permanent sauna is taking a decade-long hiatus, at least. Then this month came former greenhouse gas alarmist David Evans's article in The Australian, stating that since 1999 evidence has been accumulating that man-made carbon emissions can't be the cause of global warming. By now that evidence, Evans said, has become pretty conclusive.
Yet believers in man-made global warming demand more and more money to combat climate change and still more drastic changes in our economic output and lifestyle.
The reason is that precisely that they are believers, not scientists. No amount of empirical evidence will overturn what has become not a scientific theory but a form of religion.
But what kind of religion? More than 200 years ago, Scottish Enlightenment philosopher David Hume put his finger on the process. His essay, Of Superstition and Enthusiasm, describes how even in civilised societies the mind of man is subject to certain unaccountable terrors and apprehensions when real worries are missing.
