What gases contribute the most to increasing the Greenhouse effect? What gases are the most effective greenhouse gases? Are these the same? Why or why not?

The gases which contribute the most to the greenhouse effect are: Water vapor as consequence of evaporation, Carbon dioxide by the use of fossil fuels for industrial processes and the Metane which is found in fermentations produced by specialized anaerobic bacteria found in swampy areas, Nitrous oxide produced by massive use of nitrogen fertilizers, Chlorofluorocarbons (CFCs) which have multiple industrial uses in refrigeration systems and Tropospheric ozone cause by burning of polluting energy resources, being the most effective greenhouse gases: Carbon dioxide, Nitrous oxide and Chlorofluorocarbons.
