Climate change scenario in Bangladesh: historical data analysis and future projection based on CMIP6 model

During the last two decade, Bangladesh has been experienced a critical climatic anomalies which lead to an increment in enormity and repeat of diverse climate relate extraordinary events. Climate analysts substantiate that around the world temperature and precipitation plan is expected to change, which may result in significant influence on cultivation, work, and organic framework. Bangladesh is subsequently likely to confront critical challenges within the coming decades. In orchestrate to sufficient get it this complex, lively wonders, Analyzing chronicled Climate modify scenarios as well as anticipating its future designs may be a exceptional concern for examiner. This consider focuses to analyzes irrefutable climatic data from (1901-2020), and expect future temperature and precipitation plans in Bangladesh utilizing CMIP6 data. The data utilized in this think-around (Observed data is from CRU TS 4.05 and future data is from CMIP6) have been obtained from WorldClim v2.1. Distinctive techniques tallying relationship, relapse, standard deviation, relationship system, percentiles, cell bits of knowledge, and IDW presentation were performed to analyze the designs, changeability and spatial plans of temperature and precipitation. This think around revealed that Over the irrefutable consider period (1901-2020) Bangladesh has been experienced a vital warming drift with an normal increase in temperature 2 °C and with annually decay of the in general precipitation 607.26 mm adjacent to a move towards drier conditions in show disdain toward of frail relationship with more smoking a long time. Projected climate models talks to that Bangladesh slightest temperature is expected to expand from 1 °C to 4.4 °C as well as most extreme temperatures from 1 °C to 4.1 °C by 2100. In expansion, anticipated precipitation is expected to amplify by 480.38 mm, with the most prominent rises amid storm months. Regional assortments in temperature and precipitation are once more expected, with the Southeast (SE) likely experiencing the first vital warming and the Northeast (NE) seeing the preeminent critical increase in precipitation. In this study highlights the significant impacts of climate change on vulnerable communities in Bangladesh's southwestern coastal region, emphasizing the need for targeted adaptation strategies, local knowledge integration, and proactive national and global level policies to address and manage climate-related challenges.
