According to the recent study led by scientists from Columbia University, the Antarctic Ozone hole is shrinking in the second half of India and it will be a great trouble for the rest of the whole world. Countries like India are expected to be the prime target of its effect.

The study published on June 13 reveals that; the closing of the Ozone hole will result in a drastic climate change near the equator. The Ozone layer saves the earth by absorbs harmful ultraviolet rays of the sun. It is in the lower stratosphere, which is just above the troposphere (from the planet’s surface to a height of about 12-km). This significant ozone depletion is caused by excessive use of household and commercial aerosols that contains chlorofluorocarbons (CFC); it has a severe negetive effect on the public health like cancer and many other skin disease. However the production of CFC has been controlled across the world in accordance with the Montreal Protocol, signed by 191 countries.

Now a completely reverse situation is expected as a consequence of the closing of Ozone hole. According to which the region in the Southern Hemisphere is in great danger. Lorenzo M. Polvani, a professor of Physics and Mathematics, who is the major investigator in this research, expressed his surprise over this finding. He said that it was indeed unexpected that the closing of Ozone hole, which is supposed to occur in the next 50 years, is going to harm the climate to such a great extent. The tropospheric winds in the Southern Hemisphere have been accelerating closer to the planet’s pole in the last few decades. This is largely due to the increase in greenhouse gases and decreasing of ozone. This part is completely overlooked by the IPCC models, which says that the effect is in a very slow continuation. But the present finding is a sharp contrast to this, visualizing an utter change in the world. Because India is one among the countries situated very close to the equator, it can not escape from this atmospheric change.

What a sudden twist of natural forces! Few years earlier Ozone hole was a trouble, now we read that closing of that hole is a trouble.
