Abstract

Bangladesh is going to be the worst-hit country from the climate change. The impacts of climate change at specific warming levels (SWLs) of 1.5°C, 2°C, and 4°C upon the natural and social systems of Bangladesh are assessed. Eleven regional climate models' findings show that the average Bangladesh summer temperature is likely to rise from 3.24°C to 5.77°C while the mean annual precipitation is likely to increase up to 25% by the end of the century. The yield trends of Bangladesh in terms of Boro and Aman rice are projected to gradually decrease from 2-15% at a specific warming level of 1.5°C, 5-20% at a specific warming level of 2°C, and 5-25% at a specific warming level of 4°C. A few adaptation options are proposed for different SWLs and sea-level rise. Managing climate for SWLs could be for ‘short term' up to 2020, ‘medium term' up to 2050, and ‘long term' up to 2080. The end goal is a sustainable, resilient, and transformed Bangladesh, where additional policy documents, strategies, and action plans to mainstream adaptation to combat climate change are necessary.
