Possible Climatic Changes from Carbon Dioxide Increase in the Atmosphere,mely low, and heating due to ultraviolet radiation absorption by ozone and cooling due to infrared emission by ozone and carbon dioxide become predominant. In the mesosphere, above 50 km, the cooling effect of carbon dioxide is the most important.
