Professor Rajaraman, the Chief Guest of the event in his address revealed that Global Warming can lead to melting of Glaciers to result in the rise water level in the sea. If we cannot control, even if a minimum rise of 1 meter increase in water level in the sea may destroy the civilization. To overcome this problem, we need to control the carbon dioxide in the atmosphere. Making use of solar energy and nuclear energy in our day-to-day life can help us in this direction.
