Is there any literature on N2O geoengineering? I've not seen any, despite searching.
It's highly persistent (~century) and has a high GWP (~300). It seems that the principal sink is soil bacteria, which relies on (very slow) gas exchange through the soil surface layer. AFAIK, total mitigation is very difficult (as 3/4 is from agriculture) - although partial mitigation can be achieved by better fertiliser practice, etc. (cross posting due to expertise in soil on the carbon list) Sources https://www.epa.gov/ghgemissions/overview-greenhouse-gases https://www.tandfonline.com/doi/abs/10.1080/00380768.2012.733869 Andrew -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
