In Mumbai on Thursday, heavy rains and high tides caused seawater to seep into the city and fish were seen floating on the railway tracks of local trains. The incident has raised the threat posed to cities like Mumbai by rising water levels along India's coastline.

According to a report, the sea level in India has risen by about 6.5 cm in the last 40-50 years. As much as has increased. During this time the sea level rises by 1.3 mm each year. Increased. Rising sea levels could increase the risk in coastal areas, including cities like Mumbai, Chennai and Kolkata.

An Earthquake Ministry official said rising sea levels could slowly damage coastal areas and increase the risk of storms, tsunamis, coastal floods, high tide damage and coastal erosion and erosion. The ministry analyzed long-term data on sea level changes and monthly average sea level at 11 major ports, noting that sea levels along the Indian coast are changing differently.

According to this study, the sea level on the Indian coast has increased by 1.3 mm annually during the last 40-50 years. Thus, the sea level on the Indian coast has risen by 6.5 cm in the last five decades. Has increased.

According to a United Nations report, rising coastal water levels will affect many areas of the world's 10 countries by 2050, including India. In November last year, Union Minister Babul Supriyo told the Rajya Sabha that the sea level on Indian shores had risen to 8.5 cm in five decades. Has increased.

Of the 11 major ports included in the study, West Bengal's Damand Harbor is experiencing the fastest rising sea level. Figures from 1948 to 2005 were used for Diamond Harbor and the sea level rose by 5.16 mm annually.

The sea level for Kandla port has increased by 3.18 mm per annum from 1950 to 2005. Figures from 1964 to 1991 were used for Okha port of Gujarat and the rate of change in sea level was 1.50 mm. Was delivered. For Mumbai, the sea level rose by 0.74 mm from 1878 to 2005.

Floods will cost the world 14 14.2 trillion

If nothing is done about the rising sea level in the world, by the year 2100, sea floods could cost the global economy 14 14.2 trillion, which is about 20 percent of the world's GDP.

According to a report published in the journal Science Reports, rising sea levels by the end of this century, 2100, will inundate the homes of millions of people living along the coast. Concerns about rising sea levels are similar to climate change, said Ibur Kirezky of the University of Melbourne.

As a result, by the year 2100, an estimated 290 million homes could be flooded. Rising sea levels will have a serious impact on countries bordering the Bay of Bengal, including the United States, northwestern Europe and India, Indonesia, China and northern Australia.
