The results of research on the greenhouse effect have shown, among other things, that the concentration of trace gases occurring in the atmosphere such as carbon dioxide, methane, nitrous oxide, ozone and halocarbons have grown significantly since the ore-industrial times. During this period, the CO{sub 2} level has risen 30% to nearly 360 ppm from a pre-industrial era level of 280 ppm. On the basis of a variety of evidence a consensus is emerging among researchers that humans beings, primarily through their burning of fossil fuels, are already perturbing Earth`s climate. All specialists agree that without drastic steps to curb greenhouse gas emissions, the average global temperature will increase 1 to 3.5{degrees}C during the next century because effective level of carbon dioxide are expected to double sometime between the years 2050 to 2100. It may be that human-generated emissions of carbon dioxide will have to be reduced by as much as 50-80% to avoid major climate changes. Such a reduction in the CO{sub 2} emissions rate probably cannot be accomplished without a massive switch to non-fossil energy sources. However, it has been proposed that emissions from fossil fuels can be moderated by three strategies: exploiting the fuels more efficiently, replacing coal by natural gas and by recovering and sequestering CO{sub 2} emissions. A rough analysis, based on the use of currently accepted values, shows that natural gas is preferable to other fossil fuels in consideration of the greenhouse effect and improvements can be obtained if natural gas is upgrading by scrubbing the carbon dioxide out of it.
