Jay Lehr has an interesting piece on global warming in the Chicago Sun-Times in which he notes the way in which science is politicized beyond all recognition in the global warming debate:
A few years ago, R.J. Braithwaite’s peer-reviewed article in Progress in Physical Geography described a “mass balance analysis” he conducted of 246 glaciers sampled all around the world between 1946 and 1995. That’s 50 years of data. Braithwaite found some glaciers were melting, while a nearly equal number were growing in size, and still others remained stable. He concluded, “There is no obvious common or global trend of increasing glacier melt in recent years.”
But if your goal is to frighten the public into thinking humans are causing global warming with potentially catastrophic consequences, there is no shortage of melting glaciers to report upon. By some estimates, 160,000 glaciers exist on Earth. Only 63,000 have been inventoried, and only a few hundred have been studied in the detail described by Braithwaite.
The partisans of global warming have done a rather good job of marginalizing the many scientists who dissent from the “majority” view on global warming. While there’s little doubt that temperatures are increasing on average, the causes, effects, and significance of those increases are very much in debate. The so-called “hockey stick” graph showing a sudden and dramatic temperature increase has beeen shown to be based on distorted evidence. Because one glacier is melting it doesn’t mean that all glaciers are. The plural of “anecdote” is not data.
The problem with the whole global warming movement is that it isn’t science – it’s ideology. The doctrine that global warming is being caused by man is a given for this movement, and evidence to the contrary is being systematically ignored or brushed aside. Recently a group of Canadian scientists have put together a documentary dissenting from the global warming line, but Canadian broadcasters won’t touch it.
Science isn’t about condemning and brushing aside dissenting opinions. Yet the scientific community’s political ideologies routinely cause them to dismiss contrary evidence on the issue of global warming. That isn’t science, it’s religion, and the cult of global warming seems to have found many disciples among those who normally pride themselves for their rationality.
