The ozone is finally healing and could be completely repaired by 2060

Scientists at NASA said they have located the largest ozone hole ever recorded in a report released

"It's really good news", Paul Newman, chief Earth scientist at NASA's Goddard Space Flight Center and the report's co-author, said.

The UN estimates that Northern Hemisphere and mid-latitude ozone should heal completely by the mid-2030s, followed by the Southern Hemisphere in the 2050s and the polar regions by 2060. The fact that the ozone layer plays a decisive role in countering excessive amount of solar radiation and ultraviolet rays, so that the task of saving and restoring a place of honor is not the first decade.

It shows that the concentration of ozone-depleting substances continues to decrease, leading to an improvement in the layer since the previous assessment carried out in 2014.

In his opinion, the global success of the world initiative lies in the commitment by the 197 countries that gathered on Tuesday in Quito to define mechanisms to end the use of substances that deplete the ozone layer. It's a big deal since 10 percent of the upper ozone layer was gone in the 1990s, Newman told CNBC. This year, the ozone hole over the South Pole peaked at about 9.6 million square miles.

The ozone layer starts at about 6 miles (10 kilometers) above Earth and stretches for almost 25 miles (40 kilometers); ozone is a colorless combination of three oxygen atoms. Newman added that if we hadn't made these changes, two-thirds of the ozone layer would have been destroyed by 2065.

"We are only at a point where recovery may have started", Toon said, pointing to some ozone measurements that haven't increased yet.

Scientists say the Antarctic ozone hole is expected to gradually close, and that the entire ozone layer will return by the 2060s to levels last seen in the 1980s.

Another problem is that new technology has found an increase in emissions of a banned CFC out of East Asia, the report noted.

Earth's protective ozone layer suffered the consequences of man-made climate change, but it is finally recovering. Global implementation of the Kigali Amendment, which should enter into force on 1 January 2019, would prevent up to 80 billion tonnes Carbon dioxide equivalent of emissions by 2050, or the equivalent of 0.4% of global warming, by the end of the century.

The replacements that are now being used to cool cars and refrigerators have to be replaced themselves with some chemicals that will not be worsening the global warming.

In the meeting, which will last until this Friday, the results of the four-yearly report carried out by the Scientific Evaluation Panel of the worldwide agreement were presented, which leaves the experts in a mood of optimism and hope. "That will be for our grandchildren to do".
