Global Warming: Science And Politics Work In Different Ways.





4/27/07
In science, there is a scientific method that requires a survey of what has been learned before and the need for data and a supporting theory or hypothesis to advance. If there are no data or an insufficient set of observations or measurements to support a strong theory then the guess [elegantly known as a hypothesis for lack of something more formal] remains what might be accepted by some or all. The hypothesis is open to criticism, comment and other views in science until a law is found—that settles the matter. Those who question laws are not scientists unless they can show exceptions to laws then they really have a breakthrough to present and scrutinize. There were many ‘accepted’ theories on most aspects of science that were found to be worthless in the last few centuries. We still have a flat earth society. Check out this interesting link: http://www.alaska.net/~clund/e_djublonskopf/Flatearthsociety.htm

Two-time Nobel Prize winner (Chemistry and Peace) Linus Pauling advocated consuming mega doses of ascorbic acid (vitamin C) to solve some medical problems and avoid disease, which was widely accepted and then shown to be ineffective.http://en.wikipedia.org/wiki/Linus_Pauling. Who knows what data he was looking at. He had tremendous influence stemming from his work in chemistry and had a strong consensus following his views.

There were numerous ‘studies’ on silicone breast implants that were ‘accepted’ by the ‘scientific community’ despite experiments to the contrary. These devices caused several systemic diseases it was 
shown: http://en.wikipedia.org/wiki/Breast_implant#Systemic_illness_and_disease. If we squabble over data and studies with ‘experts’ divided in opposing camps with conflicting opinions then what can we say?? We can state that the ‘opinions of experts’ and the ‘scientific conclusions” are faulty. Perhaps both views are incorrect. Several studies have shown that the augmentations are not associated with disease although the lawyers might take exception to this. Then, there was the battles of asbestos.

Any particular segment of science becomes satisfied to all scientists, except heretics, certain politicians, witches, hired lawyers and the mentally ill, when firm laws are found, discovered, guessed or derived and shown to predict and describe observations. The transmutation of lead into gold was once “accepted” by kings and paupers alike. They were shown the process and did believe. Once the scientist can calculate the outcome then there is no ‘consensus’ about what is going on in that particular area. Newton’s laws of motion were originally guesses [no proof exists even today for f =ma] and he happened to guess correctly except for the singular case of the atomic scale, which was beyond his reach. We can now calculate the outcome of any kinetics or kinematics experiment at any time and get a precise answer. We can circumnavigate the moon thanks to Newton, who guessed correctly but gave no mathematical proof. No proof has been found.
The issue of global warming is political in nature and has little scientific basis. In global warming measurements, we have to look at the data set and the time scale, some history and some short term measurements to decide if we can predict the change in global temperatures. Since a reasonable time span to look for relevant data to predict future weather spans is 10,000 years or more (which is not much out of 4-5 billion years and perhaps this ought to be extended to 500,000 years) we need some data points throughout that span along with the uncertainty of the measurement. What was the mean surface and upper atmosphere temperatures every century for 10,000 years? That requires some precise measurements and some agreement on how this might be done on a whirling earth with cyclic weather seasons. What we actually have is a limited set of data of temp measurements in limited places on the globe We have a scant 30 years of precise satellite data to go on that shows essentially no change within the noise level. That does not cover a significant range. With poor certainty, how can we influence public policy when the key numbers of global temperature measurements might be found to be 1 degree +/- 5 or ten degrees. 

One has to have a confidence limit to numbers and it takes many numbers from several sources on the planet to come to some ‘average’ or mean surface temp.
A potential danger in any scientific prediction usually lies in a faulty extrapolation from an existing data set. Given the short length of time of precise measurements in our weather history we can fall into several traps. How do you extrapolate? It matters not if your data set is ultra precise if indeed the data period is small compared to the outer boundaries of the system. Is there a trend or a cyclic phenomenon present? Is this a second or third order system? We could, for example, take precise daily measurements in, say August, of any year and use those data to predict what might happen in December or June of the same or any other year. This process is folly because the extrapolationist’s ignorance of the cyclic nature of the process defeats the validity of the process. The precision of the August data, even say down to 0.00000001 % error) has nothing to do with the temperatures in February of any future or past year. That ought to be obvious all but single-issue political activists, lawyers and the ignorant. The use of tree rings to ‘correct’ data in the global warming debate when there is a need to get temperature averages to within 0.1 deg C is folly. http://unisci.com/stories/20011/0208013.htm. Read this for a good laugh. The same goes for reported ocean temperatures taken in the 19th and 20th centuries with a thermometer and wood bucket on sailing ships. How accurate can they be given the currents and changes in weather. What happens when a storm comes up? Skip the measurement? What about cloudy days?

We don’t have enough data to show that mean surface temperatures, that, according to history, have varied significantly in the last 10,000 years, are cyclic or not or controlled by sun energy, which could be cyclic or not. We think sun spots are cyclic but have little data on that one. It is very difficult to come up with a mean surface temperature given the several thousand sections of the planet as defined by one area proscribed by a single degree of latitude and a single degree longitude.

Thus, the current scientific product of this political adventure rests in the crude guessing stage and can (and has) produce several either meaningful or fanciful predictions. We were warned of some 14 major hurricanes last year and got zero as a result. A 0/14 is a very poor result from ‘experts’ using highly sensitive measuring devices and super computers to make predictions. They just look like fools. Their work on predicting earthquake is just as dismal. Nevertheless, many people believed this prediction and formed a ‘consensus’ as to the validity of this guess. Politicians need for people to believe in their causes and the truth is not necessary. In ancient Arabia there was the custom of the clergy publishing the weather forecast. It seems some scientist made the measurements and published the correlation between what they predicted and what actually happened. That did not change either the weather or the predictions. So much for the truth.

Politics need not be based on truth to be successful and, as such, needs only persuade people to believe in some outcome whether it may be verified or not. Fear or demagoguery are political factors that surpass the truth in power. That is what we see in Global Warming. There is no way to tell if the process is cyclic or undulating or not and the data set is too small to define and shape of any global temperature curve. The presumption that the temperature rises with carbon dioxide concentrations is not established. A few decades ago the scientists warmed us of Global Cooling. Oh?? Which way are we going and how do we know? We do know the glaciers melted in Kansas about 8000 years ago and that the settlements on Greenland iced over about 1000 years ago. We know the Vandals got their only chance to cross the Rhine about the 5th century A.D. when it froze over, a rare occurrence that defeated the Roman military control of that part of Gaul. We also know that the Thames River was the site of numerous consecutive decades of winter parties on the solid ice and such until 1814 when it ceased to freeze. No such parties have been held since Napoleon. Did his cannons heat up England? Did Josephine hex the Thames?

There are insufficient scientific data sets and prediction algorithms to predict just which way the global surface temperatures will go. To say that there is a consensus is to assert that Aristotle was correct about his description of science given the huge, nearly 100%, consensus in his day and for several centuries after he made his errant guesses based on no data. The effect of the sun’s radiation might well be ten times the effect of any change in atmospheric carbon dioxide gas concentrations. How can we know?
Global warming is a simple political exercise devoid of any science and it fits in well with the concepts of the Tooth Fairy, the Tarot and reading tea leaves. The politicians and activists want us to make severe changes in our use of energy, directed mostly at the United States giving India and China a pass.

That is just politics, as usual. Kids can believe in the Tooth Fairy because there is proof the next morning. Money!! Or, we can just believe in Rosie O’Donnell.
