With the emerging growth in population and increasing urbanisation characterised by growing number of vehicles in mega cities has led to a detrimental impact on environment and climate across all mega cities in India. This excessive urbanisation has overloaded the limited scarce resources and deteriorated the environmental quality, affecting natural resources and environment. This paper overviews the trend of urbanisation captured by increasing population and variations in temperature from period 1951 to 2001 for the four mega cities in India The paper also examines the trends observed in various indicators of climate change like temperature , rainfall four mega cities of India namely Delhi, Kolkata , Chennai and Mumbai for the period 2001 to 2009.The paper clearly exhibits the impact on climate change by observing the trends in temperature and precipitation .This impact is captured by computing the correlations between the urbanisation and climate change variables measured as temperature signifying that population holds a very strong significant correlation with temperature variation in all the three mega cities ruling out Delhi. Further the correlation between population, vehicles, temperature humidity and rainfall is computed for Delhi and it is concluded that the rise in population and urbanisation captured by number of vehicles have a positive and high correlation on percentage of humidity as an indicator of climate.
