This is the latest announcement by scientists from the US Oceanic and Atmospheric Administration (NOAA) and the US Aerospace Agency (NASA) on October 24 on the results of the study of the above holes " shield " protects the Earth.

Scientists from the two agencies said the hole in the ozone layer in Antarctica formed in September and October, has size of 21.32 million square kilometers, nearly the same size as the three US countries, Mexico and Canada.
