The findings are based on a new digital elevation model called CoastalDEM which shows that many of the world's coastlines are far lower than has been generally known and that sea level rise could affect hundreds of millions of more people in the coming decades. Pixabay

A rise in the sea level may put some of India’s greatest cities, including Mumbai, in the flood-risk zone, affecting a total of 36 million people in the country by 2050 – about 31 million more than previously thought, warns a study.

Worldwide, rising sea levels could within three decades push chronic floods to affect 300 million people, according to research by the New Jersey-based science organisation Climate Central.


The researchers found that West Bengal and coastal Odisha are projected to be particularly vulnerable to floods by 2050, as is the city of Kolkata.

The findings are based on a new digital elevation model called CoastalDEM which shows that many of the world’s coastlines are far lower than has been generally known and that sea level rise could affect hundreds of millions of more people in the coming decades than previously understood. Climate Central produced the model using machine learning.

The threat is concentrated in coastal Asia and could have profound economic and political consequences within the lifetimes of people alive today, showed the findings of the study published in the journal Nature Communications.

As a result of heat-trapping pollution from human activities, rising sea levels could within three decades push chronic floods to affect 300 million people

China, Bangladesh, India, Vietnam, Indonesia and Thailand are home to the most people on land projected to be below average annual coastal flood levels by 2050.

Together, those six nations account for roughly 75 per cent of the 300 million people on land facing the same vulnerability at mid-century.

Over the course of the twenty first century, global sea levels are projected to rise between about 2 and 7 feet, and possibly more.

“Based on sea level projections for 2050, land currently home to 300 million people will fall below the elevation of an average annual coastal flood. By 2100, land now home to 200 million people could sit permanently below the high tide line,” Climate Central said.

Adaptive measures such as construction of levees and other defences or relocation to higher ground could lessen these threats.

In the decades ahead, sea level rise could disrupt economies and trigger humanitarian crises around the world, said the study.

Estimates of future economic losses from sea level rise vary depending on the amount of climate pollution and subsequent rise projected, as well as other factors, such as whether future population growth, innovation or migration are considered.

Some projections indicate that flooding could cause tens of trillions of dollars in losses each year by the end of the century — or trillions per year, if extensive adaptation measures are implemented. (IANS)

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday with a focus on vaccines delivery initially. "This is going to be a pilot project for the area. The drone is developed and manufactured entirely by our scientists," Union Minister for Science & Technology, Dr Jitendra Singh told mediapersons. Singh said he himself will be launching the project at Jammu.

The drone is developed by the scientists at Bengaluru's National Aerospace Laboratories (NAL), a constituent of Council of Scientific and Industrial Research (CSIR), an autonomous Society that is headed by the Prime Minister. For now, the delivery would be limited to Covid vaccines and once successful, it would be expanded to be used for regular delivery of medicines in the remote, hilly areas.

According to him Amitabh Bachchan is a great actor in the industry.

Bollywood actor Abhishek Bachchan shares how he feels when people compare him with his father Amitabh Bachchan on the singing reality show 'Sa Re Ga Ma Pa'. He also requests contestant Rajshree Bag to sing a track 'Bahon Mein Chale Aao' featuring his mother Jaya Bachchan.

Abhishek said after looking at the performance of Rajshree, who is often compared with Lata Mangeshkar on the show, that she reminds him of being compared with his father. "Rajshree, whenever I have got the chance to watch the show, I've seen people compare you to Lata didi. It actually reminded me about how people compare me with my father and ask me how I feel about it."

According to him Amitabh Bachchan is a great actor in the industry and this is what he says to everyone making these comparisons. "My answer to them is that there's no greater actor in this film industry than Amitabh Bachchan and if I'm being compared to him, I am sure I must have done something good."

"Similarly, your voice has a different kind of magic like Lata ji and that's why people are comparing your voice with her. I feel you should always take this as a compliment," he concluded. 'Sa Re Ga Ma Pa' airs on Saturday and Sunday on Zee TV. (IANS/ MBI)

Winters in India have always beckoned for that hot, steaming bowl of tomato and pepper rasam or the mellow, millet based Raab. Certain dishes like sarson ka saag, undhiyu, nimona pulao are winter specialites in the country. Seasonal food has always been an Indian speciality -- we switch our choice in fruits, vegetables, sometimes even grains with the onset of different season. The preference of using specific ingredients during certain climates is visible in our sweets as well. It's common to find local and traditional delicacies made of jaggery, instead of sugar during the winters. Case in point -- the Nolen Gur Rasgulla, a speciality made in Odisha and West Bengal between November to February.
