Document Summary
The atmosphere insulates the earth"s surface from the loss of heat to space through a process popularly known as the greenhouse effect. When solar radiation from the sun reaches the earth"s surface, it degrades into infrared radiation and then interacts with greenhouse gases in the troposphere. Then even longer wave-length infrared radiation that results from this interaction interacts with the air molecules and increases their kinetic energy, warming both the troposphere and the surface of the earth. When all factors remain constant, when greenhouse gas concentrations change, temperatures at. Primary sources of carbon dioxide include the combustion of fossil fuels for energy and the clearing of forests for agriculture and other uses. Sources of methane and nitrous oxide include biological processes associated with agriculture and various industrial sources. Major source of the increased concentration of carbon dioxide was growth in fossil fuel use as well as land use changes.
