Alternative solution to global warming arising from CO2 emissions -: partial neutralization of tropospheric H2CO3 with NH3

The impact of anthropogenic CO2 emissions to global warming arising from the greenhouse effect is presented, and atmospheric fate of NH3 summarized. It is proposed that if the near-future attempts of the United Nations to restrict the emissions of CO2 from fossil fuels end up with failure, it would be a rational alternative to increase the contribution of anthropogenic NH3, the only alkaline gaseous molecule in the troposphere, so as to partly neutralize atmospheric carbonic acid in aerosols in the form of ammonium bicarbonate, which would be eventually swept away by precipitation to the oceans where the HCO3- species is stable. Thus, addition of ammonium N-compounds to infertile nonurban land, especially in the form of urea, is recommended to enable volatilization losses of NH3 to the atmosphere.
