We present a comprehensive analysis of temperature-related extreme events in Ny-Alesund (78.9 degrees N, 11.9 degrees E) using data from three meteorological stations. The results show that annual mean temperatures in Ny-Alesund increase at a rate that is four times faster than the global mean from 1975 to 2014 with no 'hiatus' in recent decades. The annual diurnal temperature range shows a negative trend as minimum daily temperature increases at a faster rate than maximum daily temperature. A negative trend in cold extremes and a positive trend in warm extremes are observed. This asymmetry hints at potential changes in the probability distribution of temperatures in Ny-Alesund.
