One of the arguments made by global-warming deniers is that, yes, maybe atmospheric CO2 concentrations are rising, and yes, maybe those concentrations are contributing to warming of the planet, but there are many other possible sources of the additional CO2 and therefore there is much uncertainty about how much burning of fossil fuels (coal, oil, natural gas) has contributed to the increases. Not true. Scientists have, in fact, developed a means to discriminate CO2 sources using carbon isotopes ...
