If the Greenland ice melts, the sea will rise by 7 metres. These sketches show how the areas around the Indus and Ganges (in light blue) would be covered by sea affecting the coast lines of Bangladesh, Pakistan and India if all the Antarctic ice eventually melts. While this could take many years, the worst damage will come early on as coastal towns will be under water, there will be more hurricanes, tornados, flooding, severe storm weather, spread of deserts and widespread droughts.

Storms and flooding in July/Aug 2007 affected 8 m in Bangladesh, 11 Million in Bihar, cut off or flooded 2400 villages in Uttar Pradesh and affected 3 million in Assam, due to flooding of the Ganges.

Energy- increase solar PV and CSP, energy efficiency,tarrifs, develop supercritical coal generation.
Urban public transport.
Agriculture - develop pest resistant crops .
Forest cover to increase to one third of country area.
Water efficiency use to be increased, develop salination, wetlands conservation
Ecosystems - improve land use, development, coastal protection, mangrove restoration, monitor glaciers. (ref207)
Notes:
The potential for solar power could cover all India's needs, assuming suitable storage. Tidal turbines would be llocated in the area of the Gulfs of Kutch and Cambay in the Arabian sea.
Estimates for use of surplus from crop residues would produce 17,000 MW of power from municipal and urban wastes.
At 20% blending for diesel fuel could meet 16 million tonnes of this fuel.
SW summer monsoon starts May-June. and winter monsoon starts in October. Winds are strong between March and August.
