re-radiation of I.R. rays by CO₂ and H₂O

The major greenhouse gases responsible for greenhouse effect are carbon dioxide, ozone, methane and water vapour. These gases acts like a thick warm blanket outside that surrounds this planet and regulates climate control. Water vapour causes about 36-70% of the greenhouse effect on earth, carbon dioxide CO2, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%.
