Author(s): Akram A Khan, Md. Anis Anwar, Asim Hasan
Abstract: Climate change is perhaps the biggest challenge faced by the world today and the very existence of human depends on how effectively this challenge is tackled. There are explicit evidences that atmospheric temperature has been gradually increasing since the beginning of the industrial revolution in 1850’s. The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the observed temperature increases since the middle of the 20th century is caused by increasing concentrations of greenhouse gases in the atmosphere resulting from human activity such as fossil fuel burning and deforestation. It also mentioned that the impact of emissions caused by anthropogenic activities on climate is unequivocal. The world community especially developing nations like India is at high risk due to climate change. Present paper gives an overview on the global climate change, the reasons behind climate change, the relationship between CO2 emission and temperature rise and its immediate effect on Indian climatic factors (temperature and rainfall). Temperature and rainfall both play an important role in shaping the economy of an agricultural based country. The variation of these factors from normal has been discussed in this study. The role of climate change in this variation has also been tried to figure out.
