As a part of the United Nations Framework Conventions on Climate Change (UNFCCC) negotiation, all countries were asked to provide a global commitment to reduce carbon emission while the world search and reach an agreement on mitigation and adaptation measures. As a result countries have pledged to reduce their own carbon emission in order to contribute towards meeting the global targets to arrest the process of global warming in future and in particular keeping an average rise of the global temperature within +2°C by 2100. While many would argue that the announced carbon reductions pledged by the countries of the world fell short of its targets, it is still an important first step towards a goal on combating global warming. The South Asian Countries (Bangladesh, India, Maldives, Nepal, Pakistan and Sri Lanka) are among the countries, which have also agreed to reduce their carbon emission voluntarily. This, by itself, is a new dimension in the world.
Already the world has crossed the 400ppm threshold level of carbon emissions and researchers have predicted that it is unlikely that we will be able to bring it down below 400ppm level in our lifetime (Richard A. Betts, Chris D. Jones, Knight, Keeling, & Kennedy, 2016). Their study shows that for the first time in human history, atmospheric carbon level has remained above 400ppm throughout the year. The study, therefore, prints a dim picture of the future world where rising temperature may become too costly for the survival of human race.
