The European Space Agency (ESA) has announced a positive news regarding the evolution of the dangerous hole in the ozone layer over the Antarctic, which has been spotted for the first time in the 1980s and which kept the international community in a state of alert, for the effects it could have on the planet.
According to the badysis of images taken by the Copernicus Sentinel-5P satellite in November 2017, ESA researchers concluded that the impending threat was left behind, because of the closure of the hole.
"The first copper recoveries of Copernicus Sentinel-5P show the closure of the ozone hole on the South Pole in November 2017", published on its website
"With a bandwidth of 2,600 km, the Tropomi Sentinel-5P instrument maps daily ozone worldwide and contributes to the atmosphere of the Copernicus monitoring service to support public policy. They added: [19659002] This is not the first time that positive news has been published about it, because a few years ago, scientists had identified the first signs of the disease.Healing of the ozone layer in Antarctica
Reproduction ESA On this occasion, they claimed that the hole had decreased by more than 4 million square kilometers, compared with the causes of closure , specialists have indicated that this can to be linked to the implementation of the Montreal Protocol, signed by all countries of the world in 1987, in which the use of chlorofluorocarbons is prohibited, which destroys the ozone layer.
However, despite the good news, the scientists said that they could not make sure the hole did not reappear.

This information, a few days ago, finally made it possible to detect the source which, for the past few months, has generated polluting gas emissions that have intrigued scientists.
A few months ago the alert on this topic had been raised the United Kingdom's Environmental Investigation Agency (EIA) detected the presence of CFC-11 or chlorofluorocarbons-11 in homes in construction in China
The dangerous element is used in the construction industry of the Asian giant. The very harmful gas is used as a foaming agent for the manufacture of insulating panels of houses.
Although it offers economic benefits during construction, the consequences of its use end up being worse.
