The ministry also talks of adverse impact of the climate change on India's water resources, agriculture and people's health.
A projection that direct concerns everybody in India is that by 2050 the fresh water availability in Central, South, West and southeast Asia, particularly in large river basis, will decrease while the Asian coastal areas, specially heavily populated mega-delta regions in South, East and Southeast will have the risk of increased flooding from the sea.
The ministry says an accelerated melting of the Himalayan Glaciers due to the earth's warming will have a profound effect on future water availability as these glaciers feed important rivers like the Ganges, Indus and Brahmputra.
"Gangotri glacier, one of the largest in the Himalayas has been retreating since long and more rapidly in recent decades. As the glaciers retreat, they become more fragmented and the smaller glaciers are more sensitive to global warming."
