Geographically Bangladesh situated in the tropical region where natural disaster is a common incident and still now Bangladesh is facing a plethora of natural disasters. Climate change is the main reason behind it as the emissions of different greenhouse gases like CO2, N2O, and CH4 are increasing. Bangladesh is one of the most vulnerable countries to climate change and hunger and according to Global Hunger Index- 2020, it’s under serious condition. In this study, climatic parameters (maximum temperature and minimum temperature) variations were studied for the last 31years (1988-2018) and variations of maximum rainfall and humidity were studied for the last 10 years of Dhaka city, Bangladesh. Global emission of CO2, N2O, and CH4 was calculated to find the effect on climate change of Dhaka city. From the study it is found that global emission of CO2, N2O, and CH4 gas are affecting the climatic parameters of Dhaka city. To predict future maximum and minimum temperature, maximum rainfall and maximum humidity four regression models have been established.
