A Science view


But why are we embroiled in the business of the frantic installation of renewable energy generators? HMG have, together with many Governments around the world, accepted enthusiastically the principle that carbon dioxide, adsorbs solar energy of certain wavelengths, and thus heats the air around it. Quite true, it does; indeed measuring the amount of heat adsorbed is a way of measuring the concentration of the gas.

However CO2 is not alone in being a heat adsorbing gas, the others which do the same thing are water vapour, methane, nitrous oxide, and the chloro-fluro-carbons, (which also are destructive of the ozone layer which protects us from much harmful ultra violet light).

Dr. S. Fred Singer, atmospheric physicist, Professor Emeritus of Environmental Sciences at the University of Virginia, and former director of the US Weather Satellite Service; has calculated the actual heating effect of each of these gasses. Some heat the air more than others, but the warming effect of the water vapour overwhelms the others. And the amount of man-made CO2 in the atmosphere is only part of it all. The resulting contribution of man-made CO2 to global warming is only about 0.3% of the total, when that total includes water vapour. It is insignificant.

What, however, is extremely significant, is the establishment's excuse for excluding water vapour. It is that although it might be "a little misleading" to leave water vapor out of the calculation, it is, never-the-less, "customary" to do so!"

That such excuses should so long have gone unrefuted, does, at fist sight, beggar the imagination, but two powerful influences are at work.

The first of these is the fertile ground provided by the political decision makers who, most unhappily, from Parties of all colours, do not have the technical knowledge to make to make rational judgments.

Secondly there are the business lobbyists who persuade the gullible politicians that those policies (which will enable business to make huge profits), are the ones to pursue.

A powerful cocktail resulting in policies wrong in two respects; the technology of renewable generation is fatally flawed for the reasons described earlier, and these are in pursuit of reducing a green house gas which has only the tiniest of effects on the climate.

The great shame in these matters is that though the policy makers believe that their work is soundly founded, they refuse every opportunity pressed upon them to listen to adverse advice based on the physical sciences.
