The UN's Intergovernmental Panel on Climate Change report, released in 1990, said that if CO2 and other greenhouse gas emissions continue increasing at present rates, the costal plains of Bangladesh and the Netherlands will flood by the year 2100. The small island nation of Maldives would completely disappear. This would happen if only a two foot increase in sea level were to occur.
Other nations at risk: Egypt (Nile valley), Gambia, Pakistan, and Thailand. ***
