Greenhouse gases atmospheric levels

Stabilization at the current level of emissions, also referred to as the 550-policy scenario (550 parts per million (ppm) is the atmospheric greenhouse gas (GHG) level). 

Because Article 2 of UNFCCC states as its objective the stabilisation of greenhouse-gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system , a commonly used target has been the stabilisation of the atmospheric C02 concentration. Even though it is very... 

Given this state of iron limitation, inputs of iron to the open ocean could result in enough new primary production to lower atmospheric carbon dioxide levels. Because CO2 is a greenhouse gas, cooling of the global atmosphere could result. This potential... 

Description It is a nontoxic gas and the final product of complete combustion. Actually, it is the desirable and inevitable product of combustion. However, it is recognized as the main greenhouse gas, whose increased levels in the atmosphere play a large role in global wanning. 

Since TO is a greenhouse gas, emissions of it can indirectly affect the formation of atmospheric greenhouse effect by influencing the TO concentration field. Moreover, MGC/TO precursors change the hydroxyl concentration field and, hence, the oxidation power of the troposphere. In its turn, the distribution of hydroxyl concentration in the troposphere controls the lifetime and, thus, the level of concentration of methane at the global scale.
