Evidence of sunspot involvement in climate change compelling

Over the last few years, the evidence that sunspots on our sun are directly related to climate change on earth has been steadily increasing.
I explained the exact proposed mechanism in some detail previously. Great work in this field is being carried out by Dr Henrik Svensmark and coworkers in Denmark and elsewhere.
Briefly, the mechanism is that cosmic rays impact on the earth from deep space. These cosmic rays penetrate our atmosphere and lead to the formation of cloud cover. The cosmic rays nucleate sites in the atmosphere, from which clouds form from the natural water vapour.

If one puts a spoonful of coffee powder into a cup of microwaved water, the water forms bubbles of foam on the coffee grains. This is basically the same principle as the cosmic rays forming clouds in the atmosphere.
The earth’s magnetic field, which acts as a shielding, is altered by the sun’s activity, which, in turn, is indicated by means of the number of sunspots. As the earth’s magnetic shield varies, so the cloud cover varies. Few sunspots mean a weaker earth shield, which means more cosmic rays, which mean more clouds, which mean a cooling earth.
The correlation for this effect, going back thousands of years, is good, remarkably so. Scientifically, this looks believable, and it is consistent with the theory and observation.
In contrast, the argument that man-made carbon dioxide (CO2) is causing warming does not fit the facts at all. Firstly, there was no indus- trial CO2 produced in vast quanti- ties when the Roman Warming period occurred, or when the Medieval Warming period occurred. Both are well documented in various archives, such as the historical and archaeological.
But there is more – global warming is extremely complex, and it is really naïve to believe that a relatively simple theory will explain it satisfactorily. It is far too simple just to say: CO2 traps heat and, therefore, more CO2 means more heat, and so we have global warming.
As the makers of heat-seeking missiles know very well, the CO2 in the atmosphere has ‘windows’ in it. This means that certain ‘heat frequencies’ pass through the atmosphere easily but other frequencies are trapped. It is these windows that the missile uses to hunt its prey. As a consequence, there are ‘frequency bands’ related to the CO2 cover of the earth. In various ‘bands’, the infrared passes through easily, or not so easily.
Further, CO2 can trap incoming heat from space and outgoing heat being radiated from the earth. The frequency bands linked to the CO2 also become saturated – they cannot just keep sucking up more and more heat. Essentially, this CO2 argument is very complex.
