Global warming,the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.
The temperature of the atmosphere near the earth's surface is warmed through a natural process called the greenhouse effect.Visible,shortwave light comes from the sun to the earth,passing unimpeded through a blanket of thermal,or greenhouse,gases composed largely of water vapor,carbon dioxide,methane,nitrous oxide,and ozone.Infrared radiation reflects off the planet's surface toward space but does not easily pass through the thermal blanket.
Improved automobile mileage,reforestation projects,energy efficiency in construction,and national support for mass transit are among relatively simpler adjustments that could significantly lower U.S.production of greenhouse gases.More aggressive adjustments include a gradual worldwide shift away from the use of fossil fuels,the elimination of chlorofluorocarbons,and the slowing of deforestation by restructuring the economies of developing nations.In 2002 the Bush administration proposed several voluntary measures for slowing the increase in,instead of reducing,emissions of greenhouses gases.
