Global Warming Potential
The ozone layer not only protects the earth from ultraviolet rays, it also acts as a natural greenhouse gas, but a study by the European Union entitled “Tropospheric Ozone in EU - The consolidated report” found that the production of ground level ozone has risen dramatically since the industrial revolution. This ozone is formed by the action of sunlight on hydrocarbons and nitrous oxide from the burning of fossil fuels. This ozone eventually finds its way to the troposphere and helps increase the greenhouse effect.

The IPCC report estimates that water vapor is responsible for 60% to 80% of the world’s greenhouse effect. This is termed the “natural greenhouse effect” since without it the Earth would be too cold to support life. The problem with this natural greenhouse gas is that the warmer the atmosphere gets due to rising CO2 levels, the more water vapor it can hold, thus compounding global warming.
Although the ozone depleting chlorofluorocarbons (CFC) were phased out under the “Montreal Protocol&rdq
Nitrous oxide is another powerful greenhouse gas, with a GWP of 296 over a hundred year period and a lifetime of 114 years, according to the IPCC report. It is a major component of fossil fuel burning and is also emitted during agricultural and industrial activities.
Carbon dioxide is not the only greenhouse gas contributing to global warming. There are other gases, both natural and man-made [link widoczny dla zalogowanych], that also add to the greenhouse effect. Some of these gases even have a greater global warming potential than carbon dioxide but because of their lower atmospheric volume their effect would not be in the same league as carbon dioxide. Non carbon dioxide greenhouse gases include water vapor, methane, nitrous oxide, ozone and fluorocarbons.
In the ongoing debate on global warming and climate change one greenhouse gas, carbon dioxide has emerged as the chief culprit. This is so since CO2 makes up the largest percentage of man made greenhouse gas emissions. In the Energy Information Administration (EIA) “Emissions of Greenhouse Gases in the United States, 2001” report, man made carbon dioxide made up 84% of total greenhouse gas emissions.
Methane is emitted from livestock, agricultural processes, and organic waste decay. It is also created during the production and transport of coal, natural gas and oil. The IPCC report gives methane a GWP of 62 over a 20 year period and its average atmospheric lifetime is 12 years. From these figures it can be seen that methane is a powerful greenhouse gas, but according to the US EPA “Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2003” [link widoczny dla zalogowanych], man made emissions of methane have decreased by 20%.
Gases contribute to global warming by both their ability to trap heat and their mean atmospheric lifetime. According to the Intergovernmental Panel on Climate Change (IPCC) report “Climate Change 2001: The Scientific Basis” the Global Warming Potential (GWP) of a greenhouse gas is measured against that of carbon dioxide which is given a GWP of 1. The report also gives figures for the mean atmospheric lifetimes of greenhouse gases [link widoczny dla zalogowanych], with the exception of CO2, which due to the complexity of the Carbon Life cycle, is not possible to measure accurately.
