Risk Assessment of Global Warming in Asia in the period of 1949 to 2014

Global warming is considered as one of the important environmental problem for the earth. The aim of this study is to investigate the changes of temperature in Asia. For this purpose, the monthly temperature data of 66 points were studied in all over Asia from 1949 to 2014. In this study, the changes of temperature were investigated in terms of increase, decrease and the level of significance. According to nearest points to considered urban points from NOAA site, annual average of temperature during 1949 to 2014 was calculated for each point. Also temperature change graph for each point in the period was prepared and trend of it based on regression linear equation was investigated. Different interpolation methods in GIS were used to determine the changes of temperature. According to the results obtained, 99% of Asia shows increasing and in 1% of the area doesn’t show any significant changes in 5% level. In total, amount of temperature in Asia has been increased by 0.94◦C during the study period. In a developed hazard classification for global warming, 34.7% shows slight hazard, 29.1% in moderate hazard, 33.8% in severe hazard and 2.4% in very severe hazard. According to prepared maps northern parts of the continent showed more increasing in temperature and more severe hazard.
