The present paper is an attempt to assess seasonal spatio-temporal variability of temperature in order to get an insight into nature of climate variability and its effects on various ecosystem services offered by the region. Mann-Kendall and Sen Slope statistic is a simple but a robust method of detecting trends in time series data. The rising temperature has affected the discharge pattern of the catchments. Moreover, the winter-time warming of the region leaves little scope for snow accumulation consequently, affecting the extent and distribution of snow/glacial cover. The temperature trends seem altitude dependent as is the case with eastern part of the North Kashmir Himalayas. The winter time warming has negatively affected the snow/glacier mass balance which in turn, has reduced the availability of water for rest of the seasons particularly, in the last couple of decades. The region shows some increasing trend in average temperature for all the four seasons from 1996 to 2015 against the average temperature calculated from 1977 to 1995. The highest maximum temperature has revealed an increasing trend at all the stations for almost, all the seasons.
