Unusual weather patterns in the lower layers of the atmosphere over Antarctica, have led to a dramatic reduction in the depletion of the ozone layer, to the left of the ozone, the smallest gap since the time of its discovery in 1982, according to NASA and the National Oceanic and Atmospheric Administration.
The government said that the gap had shrunk to 3.9 million square miles) for the rest of September and October, according to satellite data. The spike in the hole, it was a 6.3-million-square-miles, measured on Sept. 8. During normal operating conditions, the gap is usually around the 8-million-square-mile-at this time of the year.
“This is great news for the ozone in the Southern Hemisphere,” said Paul Newman, chief scientist for Earth Sciences at NASA’s Goddard Space Flight Center, in a statement on NASA’s website. “However, it is important to recognize that what we’re seeing this year is as a result of the warmer stratospheric temperature. It is not a sign that the atmospheric ozone is all of a sudden have a quick recovery.”

A video has been posted on the NASA Goddard YouTube page, and the satellite data are described in more detail.
The ozone layer is between approximately 7 and 25 miles above the Earth’s surface and acts as a “sunscreen” for the planet, NASA added. It keeps the harmful ultra violet rays of the Sun, which has been linked to skin cancer, cataracts, immune system suppression, and can also result in damage to the plant.
The hole above Antarctica during the Southern Hemisphere’s late winter, when the Sun’s rays begin to cause the ozone-depleting reactions. This includes chlorine and bromine from man-made objects, it is released into the atmosphere, which then destroys the molecule in the ozone layer.
Although the measurements at the south pole in some parts of the atmosphere where the ozone layer is completely depleted,” the atmospheric scientist Bryan Johnson at NOAA’s Earth System Research Laboratory, said, ” it’s not all good news.
This is only the third time in the last 40 years (as of September 1998, and 2002 were the others), where the depletion of the ozone layer has been limited due to the unusual weather systems, a phenomenon that researchers are still trying to figure out.

“It’s a rare occasion that we are still trying to understand it,” said Susan Strahan, an atmospheric scientist in. “If the global warming hadn’t happened, we’d probably be looking at a lot more of the typical hole in the ozone layer.”
The Montreal Protocol of 1987 was adopted after the expiry of the scientists, a disturbing thought to be a hole in the ozone layer over Antarctica, and Australia in 1985. It was adopted by the United Nations Environment Programme. The former U. N. Secretary-General Kofi Annan has said that “[p]perhaps the most successful international agreement to date”, and it is widely regarded as a successful one, with the ozone to continue to be to recover each and every year.

A total of 197 countries, including the united states, under former President Ronald Reagan, have been the co-signers of the Montreal Protocol.
Experts believe that in the Antarctic ozone layer will recover back to levels seen in 1980 to around 2070.
