The research was conducted to determine the extent of climate change in Sambalpur district, Odisha from the year 1990 to 2019. The climate change was studied for rainfall and temperature by running Mann-Kendall test at 5% significance level on time series data for each of the 9 blocks for the time period 1990 to 2019. The resultant Mann-Kendall test statistics indicated how strong the trend in rainfall and temperature was and whether it was increasing or decreasing. For seasonal rainfall six of the nine blocks showed increasing trend but only 3 blocks showed significant increasing trend. Similarly, for maximum temperature six of the nine blocks showed increasing trend and of these six blocks five blocks showed significant increasing trend. For temperature extreme ≥ 40oC, the trend was increasing but insignificant. For temperature extreme ≥ 45oC, the trend was decreasing but insignificant. For temperature extreme ≤10oC, a significant decreasing trend was observed.
