Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in atmospheric temperature because the molecules of CO2 (and other greenhouse gases) absorb the infrared radiation from the Earth's surface.

Since then, satellite reading of temperatures and the occlusion of numerous infrared bands, ground based, aircraft and balloon measurements of same, and an ever - increasing data base of the optical properties of CO2 (and other gases, like water vapour), have helped refine radiation calculations towards determining the atmospheric heat budget.
