Rising sea levels threaten to engulf 12 Indian coastal cities by the end of the century.
By 2050, Mumbai, Chennai, Kochi, and Visakhapatnam may be nearly three feet below sea level. Nasa has identified 12 cities in India that are likely to be hit hard by climate change.
India has received grim warnings from the Intergovernmental Panel on Climate Change (IPCC).
According to the analysis, rising sea levels might submerge 12 coastal cities by the end of the century. The cities of Mumbai, Chennai, Kochi, and Visakhapatnam are among the most vulnerable.
The IPCC has come out with a new report that has grim warnings for India, which is already experiencing unpredictably changing weather patterns and environmental elements.
Rising sea levels are the most significant risk factor, with 12 coastal cities in the country facing submersion by the end of the century.
According to the climate change assessment, cities might be nearly three feet submerged by the end of the century.
Mumbai, Chennai, Kochi, and Visakhapatnam are among the cities on the list.
Nasa conducted the research after consulting the IPCC report to estimate increases in sea levels around the world.
Climate change and rising sea levels are expected to wreak havoc on 12 Indian cities if the situation goes out of control, Nasa says.
Since 1988, the IPCC has published global climate assessments every five to seven years, concentrating on changes in temperature and ice cover, greenhouse gas emissions, and sea levels around the world. Data from satellites and ground devices, as well as analysis and computer simulations, are used to make their sea-level estimates.
According to the IPCC report, sea levels surrounding Asia have been rising at a quicker rate than the global average. According to the analysis, dramatic shifts in sea levels, which occurred once every 100 years earlier, could occur once every six to nine years by 2050.
According to the IPCC Working Group I report, “coastal areas will see continued sea-level rise throughout the 21st century, contributing to more frequent and severe coastal flooding in low-lying areas and coastal erosion with extreme sea-level events that previously occurred once in 100 years could happen every year by the end of this century.”
According to the report, climate change is causing a variety of effects in various locations, many of which will worsen as the world warms.
Changes in wetness and dryness, winds, snow and ice, coastal places, and oceans are all examples. According to estimations published between 2006 and 2018, the global mean sea level is rising at a pace of roughly 3.7 mm per year.
Meanwhile, the Hindu Kush Himalayan (HKH) region’s glaciers will continue to decline, and snow cover will retreat to higher altitudes.
According to Krishna Achuta Rao, one of the report’s authors, the snow cover in the HKH region has decreased since the early twenty-first century, and glaciers have thinned, retreated, and lost mass since the 1970s.
The following Indian cities will face the brunt of climate change as they fear rising sea levels.
Mumbai: 1.90 feet
Kandla: 1.87 feet
Okha: 1.96 feet
Paradip: 1.93 feet
Khidirpur: 0.49 feet
Visakhapatnam: 1.77 feet
Chennai: 1.87 feet
Tuticorin: 1.9 feet
Bhaunagar: 2.70 feet
Mormugao: 2.06 feet
Mangalore: 1.87 feet
Cochin: 2.32 feet
While these are preliminary estimates, if current trends continue, these coastal communities might be submerged by three feet by the end of the century.
While sea levels rise, the Himalayan glaciers continue to melt, affecting over a billion people who are either directly or indirectly reliant on these resources.
Glaciers and snowmelt are important components of the Himalayan Karakoram rivers, with the Indus basin having greater importance than the Ganga and Brahmaputra basins, according to an earlier report by the Indian Institute of Technology (IIT) Indore on the glacial hydrology of rivers in the Himalayan Karakoram region.
Total river runoff, glacier melt, and seasonality of flow are expected to grow until the 2050s, then decline, according to the researchers.
