Throughout time and history, urbanization has proven itself to be a significant impact on climate in urban areas. In this study, we investigate urbanization effect on temperature trends in several regions across Vietnam based on statistical relationship between these trends and local population growth as well as the change in the annual mean temperature in the past decade by applying statistical analysis to the results. Population data from 2008-2018 and the temperature data from 1988-2018 were obtained from the Annual Abstracts of Statistics and the Institute of Hydrology and Meteorology Science and Climate Change, respectively. Although most of our findings indicate a very small correlation between temperature rise and local population growth, there were exceptions with reasonable values. The results suggest that urbanization contributes to the change in temperature trend of different regions. The type of region (based on its population) also determines if the change in temperature is positively or negatively correlated with the population growth. Furthermore, by using ArcMap, we also constructed several surface temperature maps in the past few decades in order to gain further insights into how temperature changed with time.
