    A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect on planets. The primary greenhouse gases in Earth's atmosphere are water vapor (H 2O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2O), and ozone (O3). Without greenhouse gases, the average temperature of Earth's surfacewould be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F). The atmospher
