Prince Charles on Global Warming

Prince Charles, who is heir to the British throne, has called people who deny human-made climate change a "headless chicken brigade" who are ignoring overwhelming scientific evidence.
Prince Charles may be a good figure of royalty, but he apparently does not understand detail and logic.
The detail starts with the fact that many persons, including scientists, have espoused that the burning of carbon containing fuels, such as coal oil and natural gas, increase the concentration of carbon dioxide in the atmosphere, which causes a radical climate change.
Note that few persons deny climate change. Historical records show that this is so. Questions then boil down to the following: Does an increase in atmospheric carbon dioxide affect climate? If it does, how much?
Before we answer these questions, we need to go a little deeper into the theory, which is simply that the sun's radiation hits the earth surface and generates heat. That heat would normally radiate back to the stratosphere, except that is inhibited by greenhouse gases, which act as insulation to that passage of heat, much like fiberglass insulation is used in housing to slow down interior heat gain in the summer, and heat loss in the winter.
If we measure insulation properties of gases in the laboratory, we see that carbon dioxide is almost twice is good an insulator as the major components of the atmosphere, which are nitrogen and oxygen.
However, the amount of insulation is important. One thousandth of an inch of fiberglass insulation in a house can be expected to do little or nothing compared to the usual use of 4 to 6 inches. Similarly, the concentration of carbon dioxide in the atmosphere is only 0.05%, compared to 78% nitrogen and 21% oxygen.
We can now answer the two previous questions.
Does an increase in atmospheric carbon dioxide affect climate? Yes. An increase in carbon dioxide atmospheric concentration increases the total resistance of the atmosphere to the loss of heat from the earth surface. That would tend to increase earth surface temperature, which we call global warming.
How much? Essentially none. Remember that while carbon dioxide is a better heat insulator than the other natural gases of the atmosphere, it's concentration is only 0.05%. An analogy would be that if you reduce the federal debt of $17 trillion by a few thousand dollars, you still have made essentially no dent in the debt.
