Man-made CO2 does little to increase earth’s temperature

In response to my July 9 letter, online commenter — (7/10/14, 3:14 P.M.), quotes .”When CO2 is added to the atmosphere, as a greenhouse gas it has a warming effect. This causes more water to evaporate and warm the air to a higher, stabilized level. So the warming from CO2 has an amplified effect.”

So what part does man-made CO2 play in increasing the earth’s temperature? Practically nothing. Consider that the sun is pushing about 1400 watts per sq. meter onto the upper atmosphere, when you discount absorption losses, cloud cover and other factors, you might end up with about 150 w/m2 at the surface. Consider that the heat capacity of CO2 near the surface is about 23 times less than sun’s 150w/m2 heat energy. Now consider that about 97% of all CO2 in the atmosphere is made by nature, and 3 percent is man-made. That leaves man with a puny 0.195 watts/m2 of input to heat us up for the scare mongers “Thermaggedon”

Consider also that Mother Nature has a CO2 ‘recycling capacity’ that is about 33 times greater than all the CO2 man pumps out.

Ma Nature’s CO2 reservoirs located in the oceans and land areas can hold about 80 times more CO2 than what is in the atmosphere. These reservoirs are in a constant state of flux, they absorb or emit CO2, depending on cloud cover, ocean currents, etc. So it would seem reasonable that one little burp or hiccup from her massive CO2 reservoir, and/or any variation in solar energy via sun-spot activity, will probably push man’s puny 3% atmospheric CO2 contribution into the realm of insignificance in regard to any effect on global temperatures.
