Can not quickly overcome the hole of Ozone layer

Scientists recently announced that: The hole in the Ozone layer to protect the earth will not restore itself as expected within the next two decades.

The earth's ozone layer is against 90% of the sun's ultraviolet radiation, making it possible for us to survive and live on the earth's surface. For many decades, the ozone layer was weakened by chlorine gas and Brom gas in the air - the result of man-made industrial gases. The ozone layer has formed above the southern hemisphere.

In the last few years, trying to limit this hole is wider, scientists have used chemical methods and bring hope that ozone will be restored.

Modern electronic devices that predict a breach will disappear by 2050.

A newly improved electronic device by NASA scientists and the National Meteorological Research Center recently predicted that the recovery will not happen before 2068. With this new device, it is whether clean materials for artificial satellites and airplanes will be re-examined, whether or not it is actually reproducing ozone above the Antarctic stratosphere 27 years ago.

Ozone holes are not only available in Antarctica as we often assume, but they are much wider than that in the atmospheres with less ozone than normal natural conditions.

The head of the new study, Paul Newman, a scientific researcher at Nasa's Goddard Space Flight explains: " Above the surface of the farther places further poles like in Africa or the US, the level Ozone is only 3-6% lower than the natural level Above the Antarctic, the ozone level is lower than 70% in the spring, this new research method allows us to more properly evaluate the decline. of ozone gas above the Antarctic and how they reduce the time to shrink ozone holes "

In addition, Newman and his colleagues found that the ozone hole will not begin to shrink as we know it. They show that it will not happen most until 2018, after which time the ozone layer will recover and will begin to recover faster. The new study also confirms the work Newman and his team did last year, saying that the ozone hole would not be restored before 2065.
