_mjv]oIcWw refers to the emission of infrared radiation from objects due to their temperature. Infrared radiation is emitted by objects as they absorb energy from surrounding molecules. The amount of infrared radiation emitted by an object increases with its temperature. Some key points about infrared radiation from the passage: - The main source of infrared radiation from the atmosphere is carbon dioxide. - Infrared radiation is measured in terms of the percentage of radiation emitted from an object at 1000°C. Carbon dioxide emits 35% of radiation at this temperature. - Other greenhouse gases that absorb infrared radiation include water vapor, methane, nitrous oxide, and ozone. - Infrared emissions
