英文摘要	In this study changes in the heatwave characteristics and associated population exposure for the five months (March-July) of the year is examined over India. The study considered 1.5 degrees C, 2 degrees C, and 3 degrees C global warming levels (GWL) and for two time periods, i.e., the near future (T1; 2021-2050) and the distant future (T2; 2071-2100) using the Coupled Model Intercomparison Phase 6 (CMIP6) framework. This study identifies the heatwave using the extreme heatwave factor (EHF). The findings demonstrate a significant rise in mean summer heatwave frequency, duration, and severity with increasing GWLs. With the increase in GWLs, most of the regions of India would face severe heatwave but the Himalayan, Coastal, and Northeast regions are the most vulnerable to heat waves and associated severity. The March (18-fold) and April (9-fold) months show the maximum increase in severity compared to the months of May, June, and July from the current world (1991-2020). The population exposure showed significant regional variations, with the Coastal and Northeast regions seeing the highest exposure for all SSPs and warming periods, and the Himalayan region experiencing the lowest exposure. Comparing the population under all SSP, climate change contributes more to total exposure. The total exposure increases 1.4-1.6 folds from 1.5 to 2 degrees C GWL under all SSPs over India.
