Greenland losing tonnes of ice every year


In a recent study carried out by Gravity Recovery and Climate Exchange (GRACE) it has been concluded that Greenland is losing about 200 tonnes of ice every year since 2003 which could have impact on sea levels. The latest analysis by scientists studying the changing mass of the island using satellite date backs the previously reported trend without including the last two years.
GRACE retrieves the changes in mass on the surface of the Earth by detecting subtle increases and decrease in gravity, which is directly related to the mass below the two orbiting GRACE satellites. Roughly, 200 million tonnes of ice is the amount needed to fill enough rail road coal cars to as encircle the earth. The study was carried out by Princeton University’s researcher Chris Harig and Frederik Simons. They applied a new method to analyze the GRACE data. They found that during 2003 and 2004, mass loss was centered along the eastern coast of Greenland. From 2005 and 2006, mass loss dropped in the north east but rose in the south east. Meanwhile, more mass was lost along the north east coast, especially from 2007 to 2010. The authors have used new decomposition but the sources of error and corrections are essentially the same as for other studies.
The study confirms what we already know. The data shows that global warming is increasing by the year and is a big concern for all nations around the world. It is now time for everyone to unite and find ways to reduce global warming in whatever way they can in their countries. It also calls for the increasing use of renewable energy that will help in straining the environment. Looking on the positive side, who knows, it might be a blessing in disguise. As the old saying goes “Necessity is the Mother of all Inventions”.

At your own pace

As a typical person who travels by local train in mumbai to work daily, people would be knowing the frentic pace at which the things move on stations and in train. At the epicentre is the dadar station which is the heart of local trains in mumbai which acts as crossover between western and central mumbai. It attracts about a million people daily including the people travelling in long distance trains. People have no time to halt as they are busy looking to catch another train. Stopping and waiting for 5 minutes looks like an hour with things happening in fast forward. Any outsider from any other part of the world would be awestruck by the sheer pace of the city. And the trains give the perfect example of pace  where people are fighting for every inch of space in local trains to go to their respective destination. Once you start the journey you just want to get off to your station quickly as possible during the peak hours as for once you may lose your patience to stay in the train the

FDI in Retail: Boon or Bane

As Indian Parliament has passed its verdict for FDI in Rajya Sabha and Lok Sabha, the Indian people are left amazed at how political parties that were opposing FDI have either not voted or have voted for the government. The popular opinion among the Indian public was against the FDI as government could not solve doubts relating to FDI of common people. There are also doubts that this will lead to foreign control of our economy. The government has defended its move by stating that it will help India as there will be investment from foreign retail chains. But, if that is the case then why has there been no real attempt to bring back black money, since they also have names of people that have their money stashed outside India. Also, the fact that these retail chains will generate jobs is also flawed as it will be market based and if there is a case of recession, they might as well cut jobs. They are not non-profit organization that will make investment and not make profit. They will o
