1.	(a) Rearrange the following greenhouse gases in increasing order of their relative contribution to the total global warming : N2O, CFC; CO2; C2H4, (b) What is the effect of global warming on polar icecaps ? Comment on its possible ecological impact.
Answer» (a) C₂H₄ →N₂O → CFC → CO₂ / N₂O → CFC → C₂H₄ → CO₂ (Highest) (b) (Global warming) → Rise in Atmospheric temperature → polar ice melts → increase in sea level → coastal land mass submerge.

(a) Rearrange the following greenhouse gases in increasing order of their relative contribution to the total global warming : N2O, CFC; CO2; C2H4, (b) What is the effect of global warming on polar icecaps ? Comment on its possible ecological impact.
