The May 12, “Proposed changes ill conceived” author refutes “global warming” by noting that the “greenhouse effect” is supposed to provide a kind of blanket up in the sky which sends heat from a colder position on down to the earth’s surface. He says this notion violates the Second Law of Thermodynamics which tells us that heat moves toward cold, like outer space, making the greenhouse effect unlikely. Sure makes sense to me.
But for now, let’s just say “Greenhouse Effect” is legitimate. From what I gather, about 95 percent of the greenhouse gas effect comes from water vapor. Only 0.117 percent of the greenhouse effect is due to man-made atmospheric carbon dioxide,(CO2) (these figures take into account the heat retention capabilities of the gases). If we assume 50 percent of this man-made CO2 is coming from coal fired power plants, that brings the CO2 figure down to 0.0585 percent of the total greenhouse effect worldwide from coal. If we assume the U.S.A. burns about 13 percent of the total coal being burned worldwide, the figure goes to 0.0076 percent. To me, this amount seems so puny that even the natural variability of the ocean’s CO2 absorption/emission cycle rates would render the man-made CO2 figure meaningless; especially when you consider that the oceans hold 60 times more CO2 than the atmosphere, and act as a giant heat-sink storage reservoir, releasing and absorbing CO2 from the atmosphere depending on temperature differentials at the air-sea interface. As sea temperatures go up, more CO2 is released, and vice versa.
Shut down every coal fired plant in the U.S.A. and you’ll accomplish nothing (except destroy thousands of coal related jobs in mining, railroading and power generation).
In summary, it’s the sun and ocean, and sometimes volcanoes that change climate; not man’s puny efforts.
