Traditionally, national security has been analyzed through the lenses of physical threats from invaders, extremist groups, whether within or outside of the country, and social or political unrest which may lead to destabilization. Historical evidences confirm this argument through a chain of events right from the beginning of civilization. A number of examples can be quoted on this front and the most recent are the terrorist attacks on United States of America (USA), the wave of terrorism in Pakistan and the Naxil movement in India, so on and so forth. For traditional threats, traditional mechanisms were and are used to tackle the issue.
Now, in addition to the above mentioned threats, the world is witnessing a new threat to global and national security in the form of climate change. Climate change is currently a much debated phenomena at all levels. The global community is working on different aspects of climate change. In 1992, United Nations Framework Convention on Climate Change (UNFCCC) was created to look after the climate change debate and to devise the policy to combat it. Unfortunately, UNFCCC could not produce any substantial results and extremely vulnerable countries and communities are still waiting for right interventions.
