Chennai: Entire Mumbai, parts of Chennai and Odisha might be no more on Earth’s face after a century due to drastic climate change. A major study by J S Mani - a professor of Ocean Department, IIT Madras has revealed that these cities may be at the forefront of climate change impact.

India is one of those 27 countries which are supposed to be the most affected by the rise in sea levels due to melting glaciers. The suspicions of submergence of considerable chunks of lands are not new, but this report about the complete submergence of B-town has definitely sent chilling waves throughout the country.

Professor Mani has advocated the use of mangroves, casuarinas or coconut groves to prevent disaster.

Not only that, the study has found that the moths of rivers may be pushed inland. He has warned that unless government takes some serious studies, millions of people could lose their lives.

The "Climate Change and India: A 4x4 assessment" report has already predicted 1.7-2.0 degrees Celsius increase in the annual mean surface air temperature.

Prepared by India`s Network for Climate Change Assessment (INCCA), the report also says that the coastal areas are likely to witness the maximum increase in temperature.

“Sea level along the Indian coast has been rising at the rate of 1.3mm/year and is likely to rise in consonance with global sea level rise in future”, says the report.

It is projected that by 2050, there will be a whopping 38 cm hike in sea level, which directly translates to displacement threat to approx. 25 % Indian population living along the 7517 km long coastline. It is alarming to imagine where will this enormous pool of so called ‘climate refugees’ will be accommodated in a country like India which is already facing housing crisis in main cities.

UN Report has pegged the present number of climate refugees in the world at 2.4 Crore.
Rise in the mean temperature consistently contributes to the surging sea level, which is further enhanced by the melting glaciers.

Siachen glacier, which has been reduced to a dimension of mere 76 km from the original 150 km , is enough to give you an assumption of the major threat , melting glaciers add to the rising sea level.
