उत्तर
Some components of the atmosphere such as water vapour, carbon dioxide, nitrous oxide and methane absorb heat energy reflected by the earth's surface and hence increase the average atmospheric temperature. These gases are called greenhouse gases.
Methane contributes to the greenhouse effect to an extent of 19%, and the concentration of methane has been increasing at the rate of 1.5% per year.
