Indian ocean warming at faster pace, India to witness increased heat waves, flooding: Report

New Delhi: The Indian Ocean is warming at a higher rate than other oceans, the latest report by the Intergovernmental Panel on Climate Change said on Monday, with scientists warning that India will witness increased heatwaves and flooding, which will be the irreversible effects of climate change.
The authors of the Intergovernmental Panel on Climate Change’s (IPCC) Sixth Assessment Report (AR6), “Climate Change 2021: The Physical Science Basis”, said the warming of the ocean will lead to a rise in sea levels, which will contribute to more frequent and severe coastal flooding in low-level areas.
“For a country like India, some of the increase in heat waves is masked by aerosol emissions, and reducing that is important for air quality. We will also see an increase in the heatwaves, heavy rainfall events, and the further melting of glaciers, which will impact a country like India, more compound events from sea-level rise, which could mean flooding when tropical cyclones hit. These are some of the impacts which will not go away,” Friederike Otto, one of the authors of the report, said.
Another author, Swapna Panickal, who is a scientist at the Indian Institute of Tropical Meteorology, said about 50 per cent of the sea level rise is due to thermal expansion.
“The Indian Ocean region is warming at a higher rate, which means the relative sea-level can also increase over the regions. Hence, the coastal regions will see the sea-level rise through the 21st century and it will contribute to more frequent and severe coastal flooding in low-level areas and coastal erosion. Along with this, extreme sea-level events that were previously seen once in a hundred years, could also happen every year by the end of the century,” she said. —PTI
