【 摘 要 】

ABSTRACT: Bangladesh is likely to be one of the most vulnerable countries in the world to climate change. This paper discusses the possible impacts of climate change in Bangladesh through tropical cyclones, storm surges, coastal erosion and back watereffect. The possible increase in cyclone frequency in the Bay of Bengal, lying south of Bangladesh, due to climate change is looked at by analyzing the cyclone data for 119 yr. Both qualitative and quantitative discussions are made on cyclone intensityincrease for a sea surface temperature rise of 2 and 4°C. Different scenarios of storm surges under different climate change conditions are developed by using a numerical model of storm surges for the Bay of Bengal. Possible loss of land through beacherosion due to sea level rise on the eastern coast of Bangladesh is examined. Some discussions are also made on the impacts of back water effect due to sea level rise on flood situations in the country. Finally, a few remarks are made on the adaptationoptions for Bangladesh in the event of climate change.
