Carbon dioxide in the atmosphere has increased from about 285 parts per million 250 years ago to about 380 ppm today. CO2 is a “greenhouse” gas -- it holds heat in the atmosphere -- so if humans are generating more, it should have a warming effect.
But probably not much of one. Greenhouse gases comprise less than 1 percent of the earth’s atmosphere; carbon dioxide is less than 4 percent of greenhouse gases; 96 percent of CO2 in the atmosphere was put there by Mother Nature.
Compared to variations in solar radiation and other natural forces, the effect of greenhouse gases on climate is trivial.
