... A number of scientific studies indicate that most global warming in recent decades is due to the great concentration of greenhouse gases (carbon dioxide, methane, nitrogen oxides and others) released mainly as a result of human activity... Doomsday predictions can no longer be met with irony or disdain.

Methane also remains in the atmosphere for 9 to 15 years; nitrous oxide remains in the atmosphere for 114 years, on average, and is 296 times more potent than CO2 — the gases released today will continue to be active in degrading the climate decades from now.

In a paper released for discussion in the journal Atmospheric Chemistry and Physics, Crutzen calculated that 3 to 5 percent of the nitrogen in the fertilizers used to raise crops for biofuels could end up in the atmosphere as nitrous oxide, a potent, long - lived greenhouse gas.

And a Nobel - prize winning chemist has publicized his findings that biofuels made from nitrogen - thirsty plants (like corn and canola) actually produce a net increase in greenhouse gas emissions, because they release nitrous oxide during their production.

Warming of arctic soils and thawing of permafrost thus can have substantial consequences for the global climate, as the large C and N stores could be released to the atmosphere as the greenhouse gases carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).

«Indirect» emissions often refer to gases released far from the source, like nitrous oxide that is emitted downstream from the fertilizer from which it originates.

Food production accounts for a third of all greenhouse gas emissions when one tallies those from fossil fuels used in growing, preparing and transporting food; the carbon dioxide released by clearing land for farming and pastures; the methane from rice paddies and ruminant livestock; and the nitrous oxide from fertilizer use.

Neuroscientists now know, however, that it is common for neurons to release a classical transmitter with another type of messenger, such as a gas (nitric oxide, for instance) or a neuropeptide (a small protein that can act as a transmitter).

Moreover, if the new rice supplies less carbon and other nutrients to the soil, farmers might eventually want to use more nitrogen - based fertilizers, resulting in the release of nitrous oxide, another strong greenhouse gas.

Greenhouse gases released by farming, such as methane from livestock and rice paddies, and nitrous oxides from fertilizers and other soil treatments rose 13 percent after 1990, the study concluded.

Potent greenhouse gases, such as nitrogen oxides produced by denitrifying bacteria in overfertilized Chinese farming lands or methane released by archaea in the millions of ruminant animals in Australia and New Zealand, may have contributed substantially to global warming.

It also can trigger the release of dangerous chemicals such as nitrous oxide, a greenhouse gas up to 300 times more powerful than carbon dioxide, and toxic hydrogen sulfide.

Fertilizers also release nitrous oxide, a greenhouse gas with 300 times the heat - trapping capacity of carbon dioxide.

Manure stored in lagoons releases methane and nitrous oxide, global warming gases more powerful than carbon dioxide.

Then large volumes of nitrogen will be released in to atmosphere, where natrual processes such as ligtening will convert nitrogen in to nitogen oxide gases, an almost 200 + times more poten greenhouse gas than CO2.

One should also pay attention to other greenhouse gases, particularly methane (from rice paddies, ruminant animal digestive processes, industrial processes, and distributed natural sources, some of which could be triggered to large releases by warming) and nitrous oxide (from the nitrogen cycle linking the atmosphere, plants, and bacteria, now exacerbated by extremely heavy use of nitrogenous fertilizers in agriculture; note, as does Vaclav Smil from the University of Manitoba, that fertilizer use is required to feed half the world's current population.

This overdependence causes the release of greenhouse gases such as carbon dioxide, methane and nitrous oxide, all of which contribute to decreasing the health of our atmosphere.

Agriculture is among the greatest contributors to global warming, emitting more greenhouse gases than all our cars, trucks, trains, and airplanes combined - largely from methane released by cattle and rice farms, nitrous oxide from fertilized fields and carbon dioxide from the cutting of rain forests to grow crops or raise livestock.

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.

Bullet point # 1 reads: «Global mean temperatures are increasing at rates unprecedented in human history, with human activity a major contributory factor through release of «greenhouse gases» such as carbon dioxide, methane and nitrous oxide.

Nitrous oxide, a potent greenhouse gas also known as N2O, is released as a byproduct of the bacterial conversion of nitrogen in agricultural soils, the so - called nitrification and denitrification processes.

Not only are such fires more likely as the climate changes but they also release vast quantities of carbon dioxide and other greenhouse gases such as nitrous oxide, contributing to climate change themselves.

Automobile exhaust and industrial emissions release a family of nitrogen oxide gases (NOx) and volatile organic compounds (VOC), by - products of burning gasoline and coal.

Ozone is an odorless gas that is not directly emitted into the air but is created by chemical reactions between nitrogen oxides (NOx) and volatile organic compounds (VOC)-- which occur naturally but are also produced from the burning of fossil fuels and are released in the process of drilling for oil and natural gas.

We also release other greenhouse gases, such as CFCs, methane, and nitrous oxide, in significant amounts.

Fortunately, as depicted in Figure 2 (orange «thermal down surface» arrow), some of this energy does stay in the atmosphere, where it is sent back toward Earth by clouds, released by clouds as they condense to form rain or snow, or absorbed by atmospheric gases composed of three or more atoms, such as water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4).

In addition to greenhouse gases, tar sands operations release large volumes of acid rain - causing sulphur dioxide and nitrogen oxides into the environment.
