Abstract

According to the global climate change index, Bangladesh has been identified as one of the countries facing the most vulnerability from climate change. In this proposed research, a comparative climate change trend analysis was done on various temperature and rainfall criteria for three climatic zones of Bangladesh (i.e., Comilla, Ishwardi, and Cox’s Bazar). The weather data was collected from the Bangladesh Meteorological Department (BMD), which covers the years 1950–2020 except Ishwardi station starts from the year 1961. The linear trend analysis revealed that the temperature was increased in all study stations, but Comilla station showed less increment in maximum 0.511°C and in minimum 0.546°C temperature compared to the other station. On the other hand, the Mann-Kendall trend analysis test found that the amount of rainfall that fell each year in Ishwardi, and Comilla was going down but is increasing in Cox's Bazar in Mk test 0.735. So far, the magnitude of change assessed by Sen’s Slope estimates also indicated the same trend direction for rainfall analysis with -1.67, 2.28,  -7.00 Ishwardi, Cox’s Bazar and Comilla respectively. Overall, the study found that the climate pattern of the Comilla district is much better for people and farming activities than the other two regions of Bangladesh. It never falls into an extreme situation in temperature, neither during summer nor in winter. It is also neither wet nor dry.
