A sea-level rise of 30 to 45 centimeters (about 1 to 1.5 feet) would displace more than 35 million people along the Bangladesh coast, according to the IPCC. The World Bank expects this much rise to occur sometime between 2050 and 2100.
Oceans around Bangladesh are projected to rise 1 meter (3.2 feet) by 2100, swallowing 17.5% of the country's land mass, according to the World Bank. The country will also see increasing rainfall, flooding, drought, and 35.8 more days above 35 degrees Celsius (95 degrees Fahrenheit) on average annually.
That means Bangladesh could lose 32% of its wheat and 9% of rice production by 2050. One analysis estimated the country could suffer over 13,000 deaths due to climate-related food insecurity. Already, about one quarter of Bangladesh's population is food insecure.
