The Earth's climate is dependent upon the radiative balance of the atmosphere, which in turn depends upon the input of solar radiation and the atmospheric abundances ot ladiatively active trace gases (1 e , greenhouse gases), clouds and aerosols Since the industrial revolution the atmospheric concentrations of several greenhouse gases, i e , carbon dioxide (CO2) methane (CH4), chlorofluorocarbons (CFCs), nitrous oxide (N2O), and tropospheric ozone (O3), have been increasing primarily due to human activities Several ol these gieenhouse gases have long atmospheric lifetimes, decades to centuries, which means that their atmospheric concentrations respond slowly to changes in emission rates In addition theie is evidence that the concentrations of troposphenc aerosols have increased at least regionally.
