Naturally occurring gases and tropospheric pollutants that absorb, reflect,
and refract the earth's infrared radiation and prevent it from escaping the
lower atmosphere are called *
ozone - depleting substance
O greenhouse gases
carbon dioxide
chlorofluorocarbons
hydrochlorofluorcarbons
O hydrofluorocarbons
O refrigerant blends
