Cities in India willbe submerged by 2100



Several Indian coastal cities will be submerged by up to 2.7 feet by the end of the century, the National Aeronautics and Space Administration (NASA) of the US has predicted.

The Intergovernmental Panel on Climate Change (IPCC) report was utilised by NASA toanalyse changes in sea levels throughout the world.

NASA has predicted that many Indian coastal cities will be submerged up to 2.7 feet by the end of the century.

The Intergovernmental Panel on Climate Change (IPCC) report was used by NASA to analyze sea level changes around the world. 

These cities and towns are Kandla,Okha, Bhavnagar Mumbai, Mormugao, Mangalore, Cochin, Paradip, Khidirpur,Visakhapatnam, Chennai, etc.

NASA's Sea Level Change Team has created a sea-level projection tool that makes extensive data on future sea-level rise from the IPCC easily accessible to the public – and to everyone with a stake in planning for the changes to come.  As per the report by IPCC and NASA scientists focusing on the state of climate science, society's continued reliance on fossil fuels is warming the planet at a rate that is unprecedented in the past 2,000 years. The effects of the increase in melting of ice sheets and glaciers, large coastal population, greenhouse-gas-emissions, and others have already resulted in a visible record of droughts, wildfires, and floods devastating communities and ecosystems in different parts of the planet. 

The report suggests the common global surface temperature has risen by over 1.1 degrees Celsius between the year 1850 to 1900, a level that has not been witnessed since 125,000 years ago, before the most recent ice age.

Several Indian cities and towns that come under the scanner of sea level forecasts are Kandla, Okha, Bhavnagar, Mumbai, Mormugao, Mangalore, Cochin, Paradip, Khidirpur, Visakhapatnam, Chennai, and Tuticorin. 

 

Which coastal cities are vulnerable in India?

Here are the Indian cities that will face the brunt of climate change as they fear rising sea levels. While these are initial projections at the current rate, if the trends continue by the end of the century these coastal cities will go under as much as three feet of water.

 

  • Kandla: 1.87 feet
  • Okha: 1.96 feet
  • Bhaunagar: 2.70 feet
  • Mumbai: 1.90 feet
  • Mormugao: 2.06 feet
  • Mangalore: 1.87 feet
  • Cochin: 2.32 feet
  • Paradip: 1.93 feet
  • Khidirpur: 0.49 feet
  • Visakhapatnam: 1.77 feet
  • Chennai: 1.87 feet
  • Tuticorin: 1.9 feet

While the sea levels rise, the continuous melting of glaciers in the Himalayas is likely to affect over a billion people, who are directly or indirectly dependent on these resources. An earlier report by the Indian Institute of Technology (IIT) Indore on the glacial hydrology of rivers in the Himalayan Karakoram region had shown that glaciers and snowmelt are important components of the Himalayan Karakoram rivers with greater importance for the Indus than the Ganga and Brahmaputra basins. The team projects that the total river runoff, glacier melt, and seasonality of flow are set to increase until the 2050s, and then decrease.
