This paper seeks to correct prevailing assumptions about Bangladesh’s susceptibility to floods, tropical cyclones and drought, and the extent to which global warming has already affected the country’s climate. Analysis of 50 years of the country’s climate and hydrological data showed no evidence that rainfall amounts have changed or that floods, tropical cyclones and droughts have increased in frequency or severity. The extent to which global warming might have affected temperatures is made uncertain by the probably greater impact on temperatures at recording stations of widespread changes in land use and the heat-island effect resulting from urban expansion around the stations. The paper reviews both the diversity of environments in Bangladesh’s coastal area exposed to sea-level rise and the possible mitigation methods. Two major conclusions are drawn: that population increase and rapid urbanisation pose more serious immediate problems for development planning in Bangladesh than climate change; and that education at all levels needs to include practical field studies that could provide all students with a better understanding of the country’s diverse and locally complex environments.
