Evaluation of Impacts of Climate Change on Temperature Variation: The Case Study of Amaravati City, India

Study on extremes of climate is necessary as they impact distressingly on life and economy. A necessity exists to know effect of change in climate on temperature for a proposed city. Thus, in the present study, the climate change impacts on temperature are assessed for the proposed Amaravati city, Andhra Pradesh state, India. Trends of temperature variations during the time period, 1981–2021, are found by considering temperature time series as daily data from POWER LaRC NASA portal. Mann–Kendall [M–K] test and Sen’s slope estimator are applied to perform trend analysis of temperature because of climate change. Various revised versions of Mann–Kendall (M–K) test and R are applied to analyze trend as the temperature time series is significantly autocorrelated. The trend analysis shows that the result of climate change on minimum temperature in the considered study area is about 1.12e − 02 ℃/year with increasing trend and is about 8.38e − 03 ℃/year with increasing trend for maximum temperature. The findings from the present study may aid to find temperature impacts because of climate change for any existing and/or proposed city for transforming as a smart city.
