AB  - In recent decades, the frequency and intensity of extreme climatic events have escalated, with global warming playing a critical role. The Intergovernmental Panel on Cilmate Change Assessment Report Sixth report confirms that hot extremes, including heatwaves, have increased globally since 1950 and will continue to intensify, leading to severe socio-economic and environmental consequences. This study examines the temporal and spatial variability of temperature extremities under current and future climate scenarios across all Indian states using the Expert Team on Climate Change Detection Indices (ETCCDI). A multi-model ensemble from the Coupled Model Inter-comparison Project Phase 6 (CMIP6) is employed under various Shared Socioeconomic Pathways (SSPs) to project climate trends for 2041–2070. ETCCDI indices such as TX10p, TX90p, TN10p, TN90p, SU25, TR25, WSDI and CSDI are applied to analyse present (1994–2023) and future (2041–2070) climate scenarios (SSP2-4.5 and SSP5-8.5) using daily maximum and minimum temperature. The projections are validated against India Meteorological Department (IMD) gridded data from 1994 to 2023. The results show that warm period duration has significantly increased, with near-year-round hot days and tropical nights predicted under SSP5-8.5 in states like Andhra Pradesh, Telangana, and Odisha. It is predicted that cool extremes will almost completely disappear at the same time, with Tx10p and TN10p falling below 5% and 4%, respectively. According to the analysis, the most trustworthy CMIP6 models for regional forecasts are CanESM5 and INM-ESM1-2-LR. These patterns highlight the critical need for early warning systems for heatwaves, localized adaptation plans, and the incorporation of climate resilience into state-level policy frameworks.
