The Arabian Sea could begin entering Mumbai at least once every year by the year 2050, according to a new study.
The rise in sea level is a resultant of global warming.
The study estimates that by 2050, around 30 crore people living in the coastal areas would be affected.
The study was carried out by a US research institute Climate Central.
The estimates were also published in the journal Nature Communications.
The report says that the havoc caused by the flood shall be worse than the previous estimates.
However, the findings do mention that the estimates did not take into account the natural or man-made coastal defense that could stop the sea water from entering into the city.
It also says that a deep and detailed study is needed to find out the accurate understanding of the areas affected.
