Global warming and climate change are currently topics of importance in environmental studies. Climate change is predominantly contributed by human activities and it presents a serious threat to nature and people. Greenhouse gasses such as carbon dioxide trap heat in the atmosphere and regulate climate. In addition, rapid urbanization and industrialization add more greenhouse gases to atmosphere and increase overall global temperature and further change the weather patterns. The unexpected weather conditions in Chennai has gained wide attention, especially after 2015 flood, Vardah and Ocki cyclones. In this study, the possible impact of climate change on rainfall over Chennai city is analysed under various Representative Concentration Pathway (RCP) scenarios. Simulations of a Coordinated Regional Climate Downscaling Experiment (CORDEX) Regional Climate Model (RCM) is downscaled using change factor method. The study results show that the intensity and frequency of extreme rainfall over Chennai is likely to increase.
