A greenhouse gas is a gas in an atmosphere that absorbs and emits radiant energy within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. 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), rather than the present average of 15 °C (59 °F). In the Solar System, the atmospheres of Venus, Mars and Titan also contain gases that cause a greenhouse effect.
Definition of "Greenhouse Gas" by Chat GPT: Greenhouse gases are gases that trap heat in the Earth's atmosphere, leading to the greenhouse effect. This effect causes the Earth to retain heat, resulting in an increase in temperature known as global warming. Common greenhouse gases include carbon dioxide, methane, and water vapor.
