New Delhi, April 29 -- A significant increase in surface temperatures within the ocean, ranging from 1.4 to 3 degrees Celsius between 2020 and 2100 is expected to have far-reaching consequences, including pushing the Indian Ocean into a state of near-permanent heatwaves.

This will intensify cyclones, affect the monsoon, and lead to a rise in sea levels, a new study led by Roxy Mathew Koll, a climate scientist at the Pune-based Indian Institute of Tropical Meteorology (IITM) has flagged concerns.

It showed that marine heatwaves (periods of abnormally high ocean temperatures) are projected to increase from 20 days per year (during 1970-2000) to 220-250 days per year, pushing the tropical Indian Ocean into a basin-wide near-permanent heatwav...
