The globe faces significant issues due to climate change caused by human activity, including global warming. Bangladesh's physical and socioeconomic characteristics make it highly vulnerable to the impacts of global warming. The legal framework in Bangladesh will significantly influence the potential responses to climate change. The Bangladeshi legal system is well-versed in addressing climate change-related issues such as flooding, inundation, and population relocation. However, global warming will probably worsen these issues in terms of scope. Therefore, it is essential to look for ways to improve legal institutions so that Bangladesh can help address both present and possible future issues. Bangladesh is located at the confluence of the Ganges, Brahmaputra, and Meghna (GBM) rivers, along with the hydro-meteorological and topographical features of the basins, making it particularly vulnerable to flooding, according to an Assessment on Community Flood Resilience in Jamuna Floodplain, an extreme flood event can liquidate up to 70% of the country, with an average annual flood covering 20.5% of the land. Bangladesh's economy suffers greatly from floods because of its low per capita income. The hydrology and water supplies of the GBM basins are expected to be significantly impacted by global warming brought by the amplified greenhouse effect, which potentially leads to more severe floods in Bangladesh. So, this research shall explore the legal ramifications of climate change in Bangladesh, highlighting the necessity of all-encompassing legal structures to tackle the complex issues brought about by temperature increases, sea level rise, and extreme weather phenomena.
