Abstract
The present study examines the trends and variance in temperature in India for the last 12 decades. Climate change occurs due to the rise in average temperature caused by human-induced factors. The literature reviewed revealed that the impact of rising temperature has been observed in Antarctic region by melting of ice resulted rise in sea level and increase in salinity in the coastal water bodies, to Asian region by change in seasonal precipitation caused either flood or drought. This paper analysed the trends in Indiaâs rising minimum and maximum temperature for the last 12 decades. The analysis exhibits that Indiaâs minimum and maximum average temperature raised to 1.44 °C and 2.14 °C over the last 12 decades. The temperature was triggered particularly during the period 1951 to 2022, recorded an average minimum of 2 °C and average maximum of 2.60 °C which is higher than the average temperature of last 122 years. The fluctuations in temperature resulted in raising temperature in India affecting the precipitation by either heavy rainfall with flood or drought. The withdrawals of freshwater from agriculture and domestic sector and freshwater stress level in India have had significant relations with both minimum and maximum raising temperature in India.
