David Ivory argues the variation in energy received from the sun has a much greater effect on global temperature balance than the effect of greenhouse gases.
The scientific and public debate on what causes global warming has been very one-sided.
The claim the so-called greenhouse gases (chiefly the natural biological products, carbon dioxide, methane and nitrous oxide) are the cause of global warming is only a theory.
It is not fact or an unequivocal truth, even though the proponents of the theory would want to claim the science behind their theory is beyond debate and supported by an overwhelming majority of scientists.
The reality is the scientists associated with climate change groupings represent only a small proportion of the total physical and biological scientists around the world, but collectively they have had an inordinately large influence on governments and policy makers.
In addition, they have adopted a condescending tactic to rebut criticism by disparaging or questioning the integrity or knowledge of those who oppose their point of view by labelling them deniers and sceptics and to claim the majority of scientists accept the so-called science of greenhouse gas-induced global warming.
