Another reason to shiver

There’s an interesting article this week entitled Global Warming: The Cold, Hard Facts? in the Canada Free Press by Dr. Timothy Bell, one of the first Canadians with a Ph.D. in Climatology (University of London), a former climatology professor at the Univesity of Winnipeg, and someone who claims an extensive background in reconstruction of past climates and the impact of climate change on human history and the human condition. Dr. Bell provides an illuminating “behind-the-scenes” look at the methods (sadly, not the Scientific one) being used to promote global warming pronouncements and suppress dissent. An excerpt (emphasis mine):



Since I obtained my doctorate in climatology from the University of London, Queen Mary College, England my career has spanned two climate cycles. Temperatures declined from 1940 to 1980 and in the early 1970’s global cooling became the consensus. This proves that consensus is not a scientific fact. By the 1990’s temperatures appeared to have reversed and Global Warming became the consensus. It appears I’ll witness another cycle before retiring, as the major mechanisms and the global temperature trends now indicate a cooling.



No doubt passive acceptance yields less stress, fewer personal attacks and makes career progress easier. What I have experienced in my personal life during the last years makes me understand why most people choose not to speak out; job security and fear of reprisals. Even in University, where free speech and challenge to prevailing wisdoms are supposedly encouraged, academics remain silent.



I once received a three page letter that my lawyer defined as libellous, from an academic colleague, saying I had no right to say what I was saying, especially in public lectures. Sadly, my experience is that universities are the most dogmatic and oppressive places in our society. This becomes progressively worse as they receive more and more funding from governments that demand a particular viewpoint.

Another cry in the wildenerness is Richard Lindzen’s. He is an atmospheric physicist and a professor of meteorology at MIT, renowned for his research in dynamic meteorology – especially atmospheric waves. He is also a member of the National Academy of Sciences and has held positions at the University of Chicago, Harvard University and MIT. Linzen frequently speaks out against the notion that significant Global Warming is caused by humans. Yet nobody seems to listen.



I think it may be because most people don’t understand the scientific method which Thomas Kuhn so skilfully and briefly set out in his book “The Structure of Scientific Revolutions.” A scientist makes certain assumptions and then produces a theory which is only as valid as the assumptions. The theory of Global Warming assumes that CO2 is an atmospheric greenhouse gas and as it increases temperatures rise. It was then theorized that since humans were producing more CO2 than before, the temperature would inevitably rise. The theory was accepted before testing had started, and effectively became a law.



As Lindzen said many years ago: “the consensus was reached before the research had even begun.” Now, any scientist who dares to question the prevailing wisdom is marginalized and called a sceptic, when in fact they are simply being good scientists.
This has reached frightening levels with these scientists now being called climate change denier with all the holocaust connotations of that word. The normal scientific method is effectively being thwarted.
