Greenhouse gases generated from human activity absorb infrared radiation from the Earth and keep it from being dispersed outside our atmosphere. This is a major cause of global warming. Compare the path length required to absorb 99% of the Earth's radiation near a wavelength of 7?m for CH3CCl3 [?(?) = 1.8 (cm atm)-1] and the chlorofluorocarbon CFC-14 [?(?) = 4.1×103 (cm atm)-1] assuming that each of these gases has a partial pressure of 2.0×10-6 bar.
