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.

In the atmosphere, a portion of the nitrogen winds up as nitrous oxide — laughing gas — which is not only a greenhouse gas that is 300 times more potent that carbon dioxide, but also destroys ozone, the gas that keeps us from getting more of a dose of UV radiation.

This proven technology has helped shift more electricity generation to natural gas, which emits less nitrogen oxides, sulfur dioxide, mercury and more than 50 percent less carbon dioxide than coal.

Some regions may even shift from being a carbon sink to being an atmospheric carbon dioxide source, 50,51,52 though large uncertainties exist, such as whether projected disturbances to forests will be chronic or episodic.31 Midwest forests are more resilient to forest carbon losses than most western forests because of relatively high moisture availability, greater nitrogen deposition (which tends to act as a fertilizer), and lower wildfire risk.50, 51,53

Reducing carbon emissions will also cut particle pollution, nitrogen oxides and sulfur dioxide by more than 25 percent.

But it's also the by - product of fossil fuel combustion, and when a refinery or power plant reduces its greenhouse gas emissions (by becoming more energy - efficient, for example), it also releases fewer smog - forming chemicals like nitrogen oxides, less of the sulfur dioxide and soot that can irritate lungs and cause respiratory disease, and fewer toxic emissions linked to cancer and neurological disorders.

The fees were raised more than tenfold on major pollutants such as sulfur dioxide, nitrogen oxide, chemical oxygen demand and ammonia nitrogen.

Warmer temperatures, added nitrogen, and the presence of basidiomycetes all worked to increase fungal biomass — and, more importantly, wood - decomposing fungi that contribute to carbon dioxide emissions.
