- According to a study by Geology department of Anna University, 1.5 sq. km of land along the Chennai coastline will be submerged by 2100.
- The sea would be moving closer to the land by 0.5 metres every year because of the increase in sea level.
- For the past 50 years, a 3.6mm rise in sea level a year has been reported in the Bay of Bengal.
- The rise in the Bay of Bengal appears to be higher than in other Asian regions.
- The increasing sea level would also force the water table along the coastline to move upwards.
- Sea water intrusion would replace the freshwater at the bottom of the aquifer.
