New Delhi. A new study shows that two Indian cities, Chennai, the capital of Tamil Nadu and Kolkata, the capital of West Bengal, are at risk from sea level rise. The study says that sea level rise this century may affect some of the major cities of Asia as well as the islands of the western Pacific and the western Indian Ocean.
The researchers further stated that if society continues to emit high levels of greenhouse gas emissions, many major Asian cities may face serious risks by 2100. Apart from Chennai and Kolkata, other Asian cities such as Yangon, Bangkok, Ho Chi Minh City and Manila are also at risk. The study was published in the journal Nature Climate Change. A study in April last year also revealed that many Indian cities located near the sea are vulnerable to flooding. 28 years due to rising water. According to the analysis, some important infrastructure and road links in Mumbai Kochi, Mangalore, Chennai, Visakhapatnam and Thiruvananthapuram will collapse in 2050 due to sea level rise.
In December last year, Union Minister Jitendra Singh said that the average sea level rise has increased from 1.3 mm/year between 1901-1971 to 3.7 mm / year between 2006-2018. Recent studies show that climate change can cause sea levels to rise by 20-30 percent in some areas, with the acceleration of major floods. In Manila), for example, coastal flooding is predicted to be 18 times greater in 2100 than in 2006, based only on climate change, the study said. But, in the worst case, it can reach 96 times more, depending on the combination of climate change and internal climate change.
