Kolkata, Sep 6 - India has launched a comprehensive scientific assessment study to keep an eye on various changes in the climate in different parts of the country.

According to Ministry of Environment and Forests officials, 127 research organisations and 220 scientists are being involved in extensive research activity on the issue. Their report will be released in November next year.

Climate change in India has led to a rise in sea level while storm surge has also become a major worry for the authorities, say experts.

'We've seen that the shoreline across the country is getting affected due to the sea-level rise. Erosion is going to take place and it will cause a major damage and human displacement in the coastal parts of the Bay of Bengal,' said Indian National Centre for Ocean Information Services director S.S.C. Shenoi.

'In Cuddalore (Tamil Nadu) also a large portion of land is likely to go under water in next 50-100 years,' he said.

Despite only about six percent of the global tropical cyclones affecting the coastal areas along the Bay of Bengal and the Arabian Sea, intensity of cyclonic storms has gone up, said S.K. Dube, professor at the Centre for Atmospheric Sciences of the Indian Institute of Technology - Delhi (IIT-Delhi).

'Storm surge has also become a major cause for concern in several coastal areas along the Bay of Bengal and the Arabian Sea. We have noticed that the intensity of cyclonic storms has increased though only 5-6 percent of global tropical cyclones affect these two areas.
