Abstract

Climate change, as well as an increase in extreme weather, are posing a serious threat to socioeconomic and livelihood security. For this study, the Cauvery delta zone (CDZ) was chosen to examine current and anticipated climate variability and trend. The four largest districts of Tamil Nadu's Cauvery delta region are Thanjavur, Thiruvarur, Mayiladuthurai, and Nagapattinam. The Indian meteorological agency provided the baseline data sets (IMD). Using IPCC AR5 RCP4.5 and RCP8.5 scenarios, the maximum and minimum temperatures, as well as precipitation, were investigated. The maximum temperature could rise to 1.1oC to 3.6oC, while the minimum temperature could rise to 2.8 to 4.5oC, according to the findings. It was also concluded that there will be 15-16% rise in the rainfall during end of the century.

Keywords: Cauvery delta zone, climate change, RCP, Tamil Nadu
