Scientists propose dumping 7400 gigatons of artificial snow on Antarctica

Mlenny/Getty What can we do to stop Antarctica’s ice sheets from disintegrating and causing a huge rise in global sea levels? A trio of scientists have simulated a radical geoengineering project to dump 7.4 trillion tons of snow on Antarctica, suggesting it could stop runaway instability in the glaciers.Recent studies have shown warmer ocean water is being pushed toward the colossal West Antarctic ice sheet, destabilizing it and speeding up the decline of its huge glaciers. The threat of these huge ice deposits falling into the ocean is immense and the overall effect of their decline has been calculated to eventually raise sea levels by approximately 10 feet (3 meters) or more, endangering cities like New York.”The real concern is that many of these glaciers have a reverse bed slope, meaning that as they retreat it exposes deeper and thicker ice to the ocean,” explains Sue Cook, a glaciologist at the University of Tasmania. “That is a very unstable position, and causes a positive feedback effect which accelerates the retreat (and hence contribution to sea level rise).”The new study, published in the journal Science Advances on July 17, proposes a drastic, decades-long geoengineering project that would pump huge amounts of ocean water to the ice sheet, adding 7,400 gigatons (7.4 trillion tons) of “artificial snowfall” and reversing the decline. Simulating the current effects on Antarctica’s ice sheets and the changes they experience with increasing snowfall, the researchers were able to map out a process that could potentially halt the ice loss.The problem? Their suggestion would be an incredibly expensive undertaking and include immense technical challenges. The authors say it would present an “unprecedented effort for humankind.”Mostly, the problem lies in pumping the water out of the ocean, which requires an enormous amount of energy. The study suggests constructing a series of 12,000 wind turbines to enable this process to take place and then pumping artificial snow into two glaciers on the West Antarctic coast. The team suggest that activity would result in a 2 to 5 centimeter drop in sea level but the added weight of artificial snow falling on the surface would shore up the glaciers, improving their stability.And the larger effects of such a scheme are yet to be ironed out. What are the lasting effects on the Antarctic ecosystem and what kind of knock-on effects would we see in ocean currents across the world? We just don’t have answers to those questions right now.What we do know is the Earth’s current default state: Burning fossil fuels and pumping tons of carbon into the atmosphere, warming the planet and causing sweeping changes like threatening a million species with extinction or, you know, the ice sheets melting. Considering the possibility of salvation in artificial Antarctic snow might be jumping a little far ahead.”Even if a geoengineering project such as this were possible, it certainly shouldn’t detract from the other urgent action which is required to reduce greenhouse gas emissions,” Cook notes.last_img read more

Captain Michael or Clement Michael Which among the two should be the

first_imgIt may be recalled that there were rumours earlier that the flick would be titled Verithanam, but a source from the film unit had stated that there was no truth in the reports. Thalapathy 63 is a sports drama which is expected to highlight the problems faced by football sports in cricket-crazy India. How Michael (Vijay) fights all the odds to ensure his team’s victory in a tournament forms the crux of the story.G Gnanasambandam, who plays the role of Nayanthara’s father in the film, says that the craze around football among Tamil youths would increase manifold after it sees the light of the day.Indhuja, Jackie Shroff, Yogi Babu and many others are part of the cast. Vijay in Simtaangaran song from his Sarkar.PR HandoutAtlee’s previous two movies with Vijay were titled Theri and Mersal, both the names were Tamil slangs. For his third film with the actor, people have been expecting him to choose the title on similar lines, but the director seems to have chosen a simple name which is apt for the content.The latest rumours claim that the makers have zeroed in on two names – Captain Michael and Clement Michael. It will be named after Vijay’s character in the film, presently referred to as Thalapathy 63.Vijay plays the role of a football coach and shortly called as CM, say rumours. Both the names gets mentioned in the movie at different times. So, the two names have been chosen although the makers are yet to finalise one title among the two.Which of the two do you like the most?

Creating opportunities for underprivileged women

first_imgWomen have come a long way after battling against all odds but still there are women, who are yet to take their first step. Le Meridien, in association with Joining Hands (a non-profit organisation), has come up with a new initiative that will train underprivileged women from economically weaker sections in the national Capital, to become a part of hospitality sector. The women will be trained in various sections within the hospitality sector, which would enhance their chance of acquiring jobs for a better livelihood.  Also Read – ‘Playing Jojo was emotionally exhausting’The training will take place for six months where 25 women will learn the intricacies of different departments under the operational section of the hospitality sector. The sole aim is to help them transform into confident women, who can face all the challenges of life.Nidhi Bhasin, trustee of Joining Hands said: “We are very excited about this initiative- the hospitality industry offers huge opportunities for employment. The sector is manpower intensive and people also good exposure to health, hygiene and general grooming. The women participating in this initiative will inspire other women in their communities and will be drivers of change towards cleaner and healthier communities.” Also Read – Leslie doing new comedy special with NetflixShe added that these women will take back home the lessons taught in this profession and it will instill confidence in them to achieve their goals. Meneka Gandhi, Union minister for Women and Child Development was present at the launch and she emphasised on the need for encouragement.  She said: “The craftsmen of this country carry legacy of unique artworks that are very well known but they don’t know how to adapt to change. This is where we have to step in to help them improve their livelihood.” The course has been designed in such a manner that it will provide a hands-on experience to the women. The students will work in the hotel for experience and be later employed if they’re good at it. For others there will be a placement drive, which will give them opportunities to work in other hotels. When Millennium Post asked about the fee structure, Nidhi Bhasin said: “We’re charging a nominal fee of Rs 300 per month so that the women, who’ve joined the course, do not take this lightly.”Some of the students were present at the launch and they happily spoke about it. “I am excited about this course. Till now we have learnt the basics as the course started in January. We are being taught the basics of English language as well such as the usage of ‘has’ and ‘have,” said Samikhsha, a student of the pilot batch.Talking more about the potential that this sector has, Meena Bhatia, vice president, Marketing and Operations, Le Meridien New Delhi said: “There is a growing need to include women in the organised sector and the hospitality industry offers great opportunities for women to join the work force. In my experience, women do exceedingly well in the key areas of housekeeping, food and beverage service, food and beverage production and the front office.last_img read more
