A greenhouse gas is a gas that both absorbs and emits radiation in the infrared range, commonly called thermal radiation or heat.
The presence of four major greenhouse gases, carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) and water vapor (H₂O) in the Earth's atmosphere leads to an increase in temperature of earth's surface. These gases trap radiation in the form of heat, causing a warming process called the greenhouse effect.
