It would be wonderful if atmospheric carbon dioxide in its present quantity could warm the Earth. All the Eliza Doolittle's in the world yearn only for a room somewhere far away from the cold night air. Alas, carbon dioxide is not the answer for a warmer world. Any middle-school science student can demonstrate the old carbon-dioxide-in-a-bottle trick. An atmosphere of 100% carbon dioxide does absorb more solar energy than nitrogen, but the effect is slight and fleeting and can only be observed in mid-summer when the sun is high in a cloudless sky.
I suspect that global warming might be occurring because the polar regions appear to be getting warmer. The geological history of Earth indicates that either global warming or global cooling is happening at any particular instant. The overall climate has never been unchanging for perhaps more than one microsecond or less. Highly educated people who claim that carbon dioxide is causing global warming are the same ones who said that moving through the air in a motorized vehicle travelling faster than 35 mph will cause the air to be sucked out of our lungs. They also said that detonating a hydrogen bomb would trigger a worldwide hydrogen fusion reaction.
Since some people fear big numbers, let me express the power plant emissions in a different way. At the present time, power companies are dumping 10 billion tons of carbon dioxide into the atmosphere every year. We can say instead that 10 billion tons equals one piddle. Earth's atmosphere has a mass of about five quadrillion tons. We can say instead that five quadrillion tons equals one ocean. Therefore, power companies dump every year one piddle of carbon dioxide into one ocean of atmosphere. In the next year or so it might be two piddles in the ocean. Now it doesn't sound so fearsome.
Nevertheless, we can pretend that carbon dioxide is causing global warming. Those who propose to remove carbon dioxide from the atmosphere have no intention of doing that because it isn't easy. Instead they will be manufacturing carbon dioxide from raw materials in a form that can be easily handled and stored. They will mask their activities behind the finest obfuscatory esotericisms conceived by man. They will claim that preventing additional carbon dioxide from getting into the atmosphere is as good as removing it from the atmosphere. The global cartel controlling this process will collect billions of dollars as a result of manufacturing CO2, and they will collect addional billions for storing the product underground. Since the determination of the percentage of carbon dioxide in the atmosphere depends on whether the measurement is made immediately downwind from a power plant or from a mountaintop, the cartel will tell us what that percentage is. Their economist advisors will tell them what number will yield the most profits. Nobody, not even me, can prove them wrong.
