Climate change is meant by any change in the normal meteorological conditions (e.g. temperature, rainfall, humidity, pressure conditions etc.) of a particular area over a prolonged period. These changes significantly affect the water resources and hydrological conditions of various regions, particularly the river basins. The changes in precipitation, its intensity and frequency, can be detrimental, both on surplus or deficit side. The climate variability is mainly responsible for the arising of drought and flood conditions across various parts of the globe. Particularly, this is of a crucial issue in a country of agro-based economy like India. Also, the gradual increase in temperature caused by greenhouse effect affects the socio-economic life of people. Moreover, the water scarcity has been arising as one of the major problems and some countries have already been in a water stressed condition. Numerous attempts have already been made to analyse the effects of climate variability on the country. In this paper, some of the remarkable research works of the past in this field is being reviewed. Also, the varying precipitation across the whole country for 1901-2012 is presented. Using the available data and analysing the results of the prior researches, a detailed analysis and future prediction for Mahanadi river basin is being made. Further, trend of temperature and precipitation in some areas of Odisha and Chhattisgarh are also shown through graphs. The possible adaptation issues and the limitations of this analysis are also presented.
