The World Meteorological Organization has also warned about India in its report. The report said that India is also at great risk due to rising sea levels. According to the report, India’s Mumbai city is most at risk.

Rising sea level A major threat to many small islands and many countries. A recent NASA assessment shows that sea levels have risen by more than 9 cm in the last 30 years. 9 cm sounds like a small number, but sea level rise like this is really bad news. Although this seems like a very small change in comparison, it cannot be ignored.

Major cities of the world are under threat

A recent report by the World Meteorological Organization (WMO) has also warned of rising sea levels. It states that major cities in the world such as Mumbai, Shanghai, Dhaka, Bangkok, Jakarta, Maputo, New York, Los Angeles, Buenos Aires, Santiago, Cairo, London and Copenhagen are at risk.

La Niña is a natural effect that periodically cools the oceans. But, even if we look at the changes it causes, sea levels are still rising. According to projections, by 2050, sea level will begin to rise at a rate of 0.66 cm per year.

How India is affected by rising water levels

The World Meteorological Organization has also warned about India in its report. The report said that India is also at great risk due to rising sea levels. According to the report, India’s Mumbai city is most at risk. In the year 2021, the Intergovernmental Panel on Climate Change (IPCC) presented its report.

Based on the report, RMSI has estimated that by the year 2050 many cities including Mumbai, Chennai, Visakhapatnam, Thiruvananthapuram, Kochi and Mangalore could be submerged due to sea level rise. However, cities were not said to be completely submerged, but it could affect villages located in low-lying coastal areas.

Surrounded by sea on three sides, India has a coastline of 7,500 km. People live in dense populations around it, so sea level rise cannot be taken lightly. NASA’s tweet of 10 August 2021 is also being posted along with this, which also talks about this reference.

According to a NASA analysis, 12 Indian cities – Kandla, Okha, Bhavnagar, Mumbai, Mormugao, Mangalore, Cochin, Paradip, Khidirpur, Visakhapatnam, Chennai and Tuticorin – are projected to experience sea level rise that has shown signs of inundation of low-lying areas.

“It is not clear that human influence has warmed the atmosphere, oceans and land,” wrote the authors of the IPCC’s Sixth Global Science Assessment. The IPCC authors concluded that the critical warming threshold of 2°C would be exceeded “during the 21st century” without deep reductions in emissions in the coming decades. The assessment, released Monday, is the collective work report of more than 200 scientists that has been endorsed by representatives from 195 countries.
