Greenhouse effects and global warming are an uprising environmental issue. The greenhouse effect is the process by which absorption and emission of infrared radiation by gases are released in the atmosphere. The major greenhouse gases are water vapor (36 -70%)‚ carbon dioxide CO2 (9-26%)‚ methane CH4 (4-9%)‚ and ozone O3 (3-7%). Since the industrial revolution‚ human activity has increased the amount of greenhouse gases‚ leading to increased levels of CO2‚ methane and troposphere ozone. Fossil fuels
