More on Climate Change

The British newspaper Express has an article on climate change. It refers to a report from the UK Energy Research Centre, which shows the number of those who resolutely do not believe in climate change has more than quadrupled since 2005. The report comes as climate change scientists working on a landmark UN report on climate change are struggling to explain why global warming appears to have slowed down in the past 15 years even though greenhouse gas emissions keep rising.
The question of whether climate change is real or unreal is deceptive in the context of the real question, which is whether the activities of mankind are increasing global temperatures.
As a straight factual question of whether the climate of the earth is variable, the answer is obviously "yes". We have good historical records to show that Earth's temperature has varied from year to year, sometimes to the extent that it has affected life conditions of living species.
Another misunderstanding involves the term "greenhouse gases". Those who propose that greenhouse gases generated by mankind are responsible for climate change ignore the fact that at a more basic level, greenhouse gases are good. Without an atmosphere composed of greenhouse gases, such as nitrogen and oxygen, daytime/nighttime variations in temperature would be so great as to not allow Earth habitation.
The climate change fear mongers claim that increases in carbon dioxide concentration through mankind's burning of fossil fuels radically increases earth temperature, because it is a greenhouse gas. While carbon dioxide is a greenhouse gas, it is not significantly different from nitrogen and oxygen, it now exists in the atmosphere at a concentration of 0.05%. At such a low concentration, it has an insignificant effect on climate compared to the major constituents of the atmosphere. If the concentration were even doubled to 0.1%, its effect would still be insignificant.
Advocates of the theory that carbon dioxide increases in the atmosphere cause an increase in global temperatures must be called to task. To merely note an increase in global temperatures or an increase in violent storms, while simultaneously noting an increase in atmospheric carbon dioxide concentrations is irrelevant. Using that sort of argument, one could say that global temperature increase is caused by an increase in the number of home runs accomplished each year in professional baseball. An obviously ridiculous assertion!
The only way that atmospheric carbon dioxide could affect Earth temperature is for it to have extremely unusual heat insulation properties, such that during nighttime, heat cannot escape from the Earth to interstellar space. If this is actually the case, I would like to be shown laboratory data demonstrating such unusual property of carbon dioxide.
