Read here (scroll down to "Nitrous Oxide From Rivers & Streams"). Over the last year, it has become painfully obvious that the IPCC "climate science" has been terribly flawed due to political agendas, resulting in the bogus and inaccurate IPCC climate model simulations. Part of the IPCC agenda is to downplay other contributors to global warming that would detract from the favored, politically correct human CO2 emissions.
As another example of the IPCC's scientific fraud incompetence, a recent peer-reviewed study reveals the IPCC's gross underestimation of another potent greenhouse gas: nitrous oxide (N2O).
"Nitrous oxide (N2O) is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. There are many sources for oxides of nitrogen: the ocean, peat bogs, microbial denitrification in soils, etc. One source that has been mostly overlooked is how much N2O is produced by flowing waters: the world's rivers and streams"..."This is yet another example of the IPCC getting its greenhouse gas sums wrong. In this case they underestimated the emission of N2O from river systems by three fold. One more reason to discount the blame CO2 first dogma put forth by warmist climate science"....."In our study [Beaulieua et al.], most streams were sources of N2O to the atmosphere and the highest emission rates were observed in streams draining urban basins...his estimate of stream and river N2O emissions is three times greater than estimated by the Intergovernmental Panel on Climate Change."
