Greenhouse gas emissions - Wikipedia

SourcesRegional and National Attribution of EmissionsEffect of PolicyProjectionsBibliographyExternal LinksSince about 1750 human activity has increased the concentration of carbon dioxide and other greenhouse gases. As of 2001, measured atmospheric concentrations of carbon dioxide were 100 ppm higher than pre-industrial levels. Natural sources of carbon dioxide are more than 20 times greater than sources due to human activity,but over periods longer than a few years natural sources are closely balanced by natural sinks, mainly photosynthesis of carbon compounds by plants and marine plankton. As a result of this balance, the atmospheric mole fraction of carbon dioxide remained between 260 and 280 parts per million for the 10,000 years between the end of the last glacial maximum and the start of the industrial era. It is likely that anthropogenic (i.e., human-induced) warming, such as that due to elevated greenhouse gas levels, has had a discernible influence on many physical and biological systems. Future warming is projected to have a range of impacts, including sea level rise, increase...Get price
