Climate change is an established fact and its impacts on water, agriculture, health, biodiversity, forest and socio-economic sectors are quite visible around the globe. According to IPCC (2007), developing and the least developed countries are expected to suffer more due to climate change as compared to the developed countries. This is true if we scale down this fact to the community level; in case of any climatic anomaly the poor people face the consequences due to lack of resources and access to information. Anthropogenic activities are mainly blamed to be responsible for the surging trend of climate related disasters occurring in different parts of the world and marginal income people are the major sufferers. After industrial revolution, emission of Green House Gases (GHGs) to the atmosphere increased drastically from industry and vehicular fossil fuel burning. Such gases have large warming potential and long life time to sustain warming process for decades to centuries. During 20th century, the increase in the global temperature was recorded as 0.76°C but in the first decade of this century 0.6°C rise has been noticed. Among 16 warmest years recorded over the globe, 9 top most were from the first decade of 21st century with ranks in decreasing order; 2010, 1998, 2005, 2003, 2002, 2009, 2004, 2006, 2007, 2001, 1997, 2008, 1995, 1999, 1990, 2000.
