Indian Ocean sea levels are rising unevenly and threatening the residents in some densely populated coastal areas of India and Bangladesh. A new study carried out jointly by the scientists from the University of Colorado and the National Center for Atmospheric Research in the USA say, sea-level rise is particularly high along the coastlines of the Bay of Bengal and the Arabian Sea, as well as the islands of Sri Lanka, Maldives Sumatra and Java. The rise in sea level of the Indian Ocean is at least partly a result of climate change, the study says according to a statement issued by the National Science Foundation. The rise, which may aggravate monsoon flooding in Bangladesh and India — could have future impacts on both regional and global climate. Key player in the process is the Indo-Pacific warm pool, an enormous, bathtub-shaped area spanning a huge area of the tropical oceans stretching from the east coast of Africa east to the International Date Line in the Pacific.
