If there is no greenhouse effect , then the average temperature of the earth will be (a) -18^@C (b) 0^@C (c) -10^@C (d) 15^@C

CO_2 and H_2 O absorbs strongly in the infrared region and its presence in the atmosphere decreases the loss of heat from the earth by radiation . This global warming is called the greenhouse effect (other gases , including the oxides of nitrogen from car exhaust freons from aerosols and refrigerators and methane from bacteria in the soil and in the rumen cows , also add to the greenhouse effect ). The concentration of atmospheric CO_2 has increased by 10% . The is resulting in the increase in the mean temperature of the earth by 2. 5^@ C , varying form 2^@ C the equator to 4^@ C at the poles . This could have dramatic effects on the climate. Which of the following is growing at a faster rate than CO_2 and thus responsible for the greenhouse effect ?
