Description: The climate of an area is usually described as average weather condition experienced over a long period of time. Climate change is the change in climatic elements over the time period that ranges from decade to centuries. This change can be measured by changes of temperature, precipitation, and ext reme weather events. This paper aims to assess climate change and its affect on Myanmar and to evaluate the climate o f Yangon City in context with g lobal warming. Climate change, in this study is variation in normal condition of majo r climatic elements of temperature and precipitation. A mount of rainfall, rainy days, and onset and withdrawal of monsoon system are considered in this study because they can highlight the affect of climate change over Myanmar. Observed climat ic data mainly fro m Depart ment of Hydrology and Meteorology and other departments concerned are used in this research. Time-series analysis, statistical co mputation, trend line analysis, and graphical analysis are applied to understand changing climat ic elements. The research reveals that climate of Myanmar is changing in line with global warming. The analysis point ou t the gradual change has pronounced since 1979. In Yangon, slight increase rainfall is found at central part of the City than surrounding area. Peak monsoon rainfall is increasing but early and late monsoon rainfall is decreasing in Yangon City. The noteworthy fact is found that the average maximu m temperature of Yangon City is increasing with a something rate wh ile the average minimu m temperature is significantly decreasing over a period of 60 years. This case leads to the increasing trend in DTR. And also contribute to decrease daily mean temperature. The decrease in daily mean temperatures per decade by decade is experience in this study. This factor opposes to global warming that is both maximu m and minimu m temperatures are increased. Therefore understanding on localized variat ion and microclimate condition are important to conduct more convenience adaptation and planning for local inhabitant. Key words; climate change, global warming,, maximu m and minimum temperature, d iurnal range of temperature (DTR), and rainfall ano malies..."
