The consequences of global warming are:
(i) Increase in atmospheric temperature: From the pre-industrial revolution era, average surface temperature has increased by 0.76°C and has been estimated to increase by 5.8°C in future.
(ii) Melting of snow in the polar areas: Increase in temperature by 2-3°C will cause melting of snow in the north and south polar areas.
(iii) Rise of sea level: Melting of snowcaps will lead to rise in sea level. Rise in sea level by one meter will submerge 5 million sq. km. of coastal areas, many populated islands, deltas and coral islands.
(iv) Change in growth and distribution of plants and animals.
(v) Decrease in crop output.
(vi) Expansion of desertification.
