NOx is a generic term for the mono-nitrogen oxides NO and NO 2 (nitric oxide and nitrogen dioxide). They are produced from the reaction among nitrogen, oxygen and even hydrocarbons (during combustion), especially at high temperatures.In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere as air pollution can be significant.hey are produced from the reaction among nitrogen, oxygen and even hydrocarbons (during combustion), especially at high temperatures.

The gases in the atmosphere that absorb radiation are known as greenhouse gases (sometimes abbreviated as GHG) because they are largely responsible for the greenhouse effect. The greenhouse effect, in turn, is one of the leading causes of global warming.The most significant greenhouse gases are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O), according to the Environmental Protection Agency (EPA). greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere.
The effects of increased greenhouse gas emissions include global warming, ocean acidification, smog pollution, ozone depletion and altered plant health, all contributing to global climate change. The main effect of increased greenhouse gas emissions is global warming. Carbon dioxide, methane, nitrous oxide and fluorinated gases all help trap heat in the Earth's atmosphere as a part of the greenhouse effect. The Earth's natural greenhouse effect makes life as we know it possible. However, human activities, primarily the burning of fossil fuels and deforestation, have intensified the greenhouse effect, causing global warming.1. Effects of increased greenhouse gas emissions. Increases in the different greenhouse gases have other effects apart from global warming including ocean acidification, smog pollution, ozone depletion as well as changes to plant growth and nutrition levels.
