In this article, is implicated another factor that greenhouse gases in global warming. Indeed, CO2 and its equivalents retain only infrared radiation of long wavelengths. These are issued naturally by the earth since always, but recently under the pretext of prestige or fashion, in hot countries is added the paintings of buildings in dark color, black in this case. These colors affect the albedo coefficient by the absorption of solar radiation and the emission of far infrared radiation that cannot cross the greenhouse gases, so partly reflected towards the earth causing global warming. Global action on reducing greenhouse gas emissions should therefore be complemented by a reduction in the dark color areas created by man.
