The Growth of Knowledge

By John Ray (M.A.; Ph.D.), writing from Brisbane, Australia.

The growth of knowledge depends entirely on disagreement -- Karl Popper

This appeared on Dr. Ray's blog linked below.   I would like to thank him for giving me permission to reproduce his works.  RK

GREENIE WATCH is in favor of things that ARE good for the environment. That the usual Greenie causes are good for the environment is however disputed. During my research career as a social scientist, I was appalled at how much writing in my field was scientifically lacking -- and I often said so in detail in the many academic journal articles I had published in that field. I eventually gave up social science research, however, because no data ever seemed to change the views of its practitioners. I hoped that such obtuseness was confined to the social scientists but now that I have shifted my attention to health related science and climate related science, I find the same impermeability to facts and logic, hence GREENIE WATCH. I may add that I did not come to either health or environmental research entirely without credentials. I had several academic papers published in both fields during my social science research career.

Since my academic background is in the social sciences, it is reasonable to ask what a social scientist is doing talking about global warming. My view is that my expertise is the most relevant of all. It seems clear to me from what you will see on this blog that belief in global warming is very poorly explained by history, chemistry, physics or statistics.

Warmism is prophecy, not science. Science cannot foretell the future. Science can make very accurate predictions based on known regularities in nature (e.g. predicting the orbits of the inner planets) but Warmism is the exact opposite of that. It predicts a DEPARTURE from the known regularities of nature. If we go by the regularities of nature, we are on the brink of an ice age.

And from a philosophy of science viewpoint, far from being "the science", Warmism is not even an attempt at a factual statement, let alone being science. It is not a meaningful statement about the world. Why? Because it is unfalsifiable -- making it a religious, not a scientific statement. To be a scientific statement, there would have to be some conceivable event that disproved it -- but there appears to be none. ANY event is hailed by Warmists as proving their contentions. Only if Warmists were able to specify some fact or event that would disprove their theory would it have any claim to being a scientific statement. So the explanation for Warmist beliefs has to be primarily a psychological and political one -- which makes it my field

And, after all, Al Gore's academic qualifications are in social science also -- albeit very pissant qualifications.

Climate is the sum of weather. So if you cannot forecast the weather a month in advance, you will not be able to forecast the climate 50 years in advance. And official meteorologists such as Britain's Met Office and Australia's BOM, are very poor forecasters of weather. The Met office has in fact given up on making seasonal forecasts because they have so often got such forecasts embarrassingly wrong. Their global-warming-powered "models" just did not deliver

A strange Green/Left conceit: They seem to think that no-one should spend money opposing them and that conservative donors must not support the election campaigns of Congressmen they agree with. 

After three exceptionally cold winters in the Northern hemisphere, the Warmists are chanting: "Warming causes cold". Even if we give that a pass for logic, it still inspires the question: "Well, what are we worried about"? Cold is not going to melt the icecaps is it?"

It's a central (but unproven) assumption of the Warmist "models" that clouds cause warming. Odd that it seems to cool the temperature down when clouds pass overhead!

To make out that the essentially trivial warming of the last 150 years poses some sort of threat, Warmists postulate positive feedbacks that might cut in to make the warming accelerate in the near future. Amid their theories about feedbacks, however, they ignore the one feedback that is no theory: The reaction of plants to CO2. Plants gobble up CO2 and the more CO2 there is the more plants will flourish and hence gobble up yet more CO2. And the increasing crop yields of recent years show that plant life is already flourishing more. The recent rise in CO2 will therefore soon be gobbled up and will no longer be around to bother anyone. Plants provide a huge NEGATIVE feedback in response to increases in atmospheric CO2.
