A great deal of focus is given to CO2 emissions and their role in the greenhouse effect, however the public is less aware of other powerful greenhouse gases.  Atmospheric nitrous oxide (N2O) concentrations have been rising since the Industrial Revolution due to anthropogenic activities. It is estimated that N2O accounts for 6% of anthropogenic greenhouse gas emissions. Due to its atmospheric lifetime of approximately 120 years combined with its heat-trapping effects,  N2O has approximately 310 times more warming power than CO2 on a per molecule basis.
