Suess effect

The Suess effect is a change in the ratio of the atmospheric concentrations of heavy isotopes of carbon (C and C) by the admixture of large amounts of fossil-fuel derived CO2, which is depleted in CO2 and contains no CO2. It is named for the Austrian chemist Hans Suess, who noted the influence of this effect on the accuracy of radiocarbon dating. More recently, the Suess effect has been used in studies of climate change. The term originally referred only to dilution of atmospheric CO2. The concept was later extended to dilution of CO2 and to other reservoirs of carbon such as the oceans and soils.
