Climate change has become most critical issue at the global, regional and local level to such an extent that climate change is considered as a gravest challenge for the mankind in the 21st century. No person, no country or no region of the world is immune to climatic changes. Past global efforts at dealing with the problem of global warming (which is most evident form of climate change) concentrated on mitigation, with the aim of reducing and possibly stabilizing greenhouse gas (GHG) concentrations in the atmosphere. The stabilization of GHG’s primarily depends upon changes in technology, discovery of new and less polluting fuels and with awareness in human behaviour towards mother earth. Further all these changes are slow in nature, that’s why tactic is seen as viable option in reducing the vulnerability to anticipated negative impacts of global warming.
