- According to data by the Ministry of Earth Sciences,Diamond Harbour in West Bengal has recorded the maximum sea level increase out of the major ports in India.
- The data says that sea level rise in the country has been estimated to be 1.3 mm/year along India’s coasts during the last 40-50 years.On the other hand, Diamond Harbour rise was almost five times higher at 5.16 mm per year.
- The data also says that the four ports in India namely (a)Diamond Harbour, (b)Kandla port (c)Haldia port and (d)Port Blair Port has recorded a higher sea level rise than the global average of 1.8 mm per year during the last 40-50 years.
- Further,the experts have said that the sea-level rise is higher in West Bengal particularly in the Sunderbans delta because of the deltaic sediment deposition as a result of the mixing of freshwater and saline water.
- According to the fifth assessment report of the International Panel on Climate Change(IPCC),the reason for sea level rise is said to be linked with global warming.
- The studies over Indian region have also shown a warming trend of 0.6°C on all India average basis mainly contributed by maximum temperatures.
