Does Ammonia contribute to Global warming?
No. Just as ammonia does not damage atmospheric ozone, ammonia, with a life cycle in the atmosphere of less than one week, does not contribute to the greenhouse effect responsible for global warming. Global warming results from the short wave, near infra-red radiation that reaches the earth from the sun. About fifty percent of the sun's radiation reaches the earth. This is absorbed by the earth's surface which re-emits the radiation in longer, far infra-red wavelengths. This re-emitted radiation is partially absorbed by gasses known as greenhouse gasses. Greenhouse gasses are either natural (CO2, water vapor, etc.) or man-made (CO2, N2O, CH4, CFC, HCFC, HFC, etc.).
