Drag the appropriate items into their respective bins. each item may be used only once. the radiative potential of greenhouse gasesthe relative role of each greenhouse gas towards the total greenhouse effect depends upon the concentration of the greenhouse gas, its rate of increase, its potential to absorb radiation, and how long it persists in the atmosphere (i. e., its residence time). the figures below show the relative importance for greenhouse gases with regard to both the natural and anthropogenic greenhouse effects, and the rate of increase for anthropogenic greenhouse gases. using figures c1 and c2 below, match each greenhouse gas to the most appropriate description. the following are the chemical formulas for some common greenhouse gases: co2 is carbon dioxide; ch4 is methane; n2o is nitrous oxide; o3 is ozone; cfc is chlorofluorocarbons; and hcf is hydrofluorocarbons. rate of increase and relative contribution of several gases to the anthropogenic greenhouse effect water vaporcarbon dioxide ozone other trace gases rate of increase (% per year) relative contribution (%) 6% 0.5 60 co ch4 n20 os cfc-11b cfc-12b 8% 15 0.2 0.5 26% 60% in the troposphere cfc-chlorofluorocarbon (human made chemical) source: data from rodhe, h. 1990. a comparison of the contribu- tion of various gases to the greenhouse effect. science 248: 1218, table 2. copyright 1990 by the aaas. © 2013 pearson education, inc. © 2012 pearson education, inc. figure c1: the relative contributions of water vapor, carbon dioxide, ozone, and other trace gases to the natural greenhouse effect of a clear sky figure c2: rate of increase and relative contribution of several gases to the anthropogenic greenhouse effect
