And although recognized that there also has been an enormous increase of nitrogenous oxides (reactive nitrogen) in the atmosphere (molecules that can adsorb much more energy than carbon dioxide) their much lower concentrations is hardly getting any attention, when global warming is discussed.

Using business - as - usual scenarios for reactive nitrogen creation and CO2 emissions, several projections suggest that O3 - related human mortality and crop damage will rise sharply in the next few decades, especially in tropical and subtropical regions where rising temperatures and rising NOx concentrations will interact synergistically to produce more O3.

More nitrogen is now converted into reactive forms by industry than all by all the planet's natural processes and our industrial and agricultural processes are causing a continual build - up of long - lived greenhouse gases to levels unprecedented in at least the last 800,000 years and possibly much longer.
