Greenhouse gas
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range. Increasing greenhouse gas emissions cause the greenhouse effect . [1] The primary greenhouse gases in Earth's atmosphere are water vapor , carbon dioxide , methane , nitrous oxide and ozone . Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F), [2] rather than the present average of 15 °C (59 °F). [3] [4] [5] The atmospheres of Venus , Mars and Titan also contain greenhouse gases.

Greenhouse gases are components of the atmosphere that contribute to the greenhouse effect . Without the greenhouse effect the Earth would be uninhabitable; [1] in its absence, the mean temperature of the earth would be about −19 °C (−2 °F, 254 K) rather than the present mean temperature of about 15 °C (59 °F, 288 K) [2] . Greenhouse gases include in the order of relative abundance water vapor , carbon dioxide , methane , nitrous oxide , and ozone . Greenhouse gases come from natural sources and human activity. |

Greenhouse gases (GHGs) are gaseous components of the atmosphere that contribute to the greenhouse effect . Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases. [1] |

Greenhouse gases (GHG) are gaseous components of the atmosphere that contribute to the greenhouse effect . The major natural greenhouse gases are water vapor , which causes about 36-70% of the greenhouse effect on Earth ( not including clouds ); carbon dioxide , which causes between 9-26%; and ozone , which causes between 3-7% (note that it is not really possible to assert that such-and-such a gas causes a certain percentage of the GHE, because the influences of the various gases are not additive. The higher ends of the ranges quoted are for the gas alone; the lower end, for the gas counting overlaps). [1] [2] . |
