Earth’s Ozone Layer shows early signs of thickening after years of depletion
Researchers from the World Meteorological Organization (WMO) and the UN Environment Programme (UNEP) have shared good news that the ozone hole that appears annually over Antarctica is no more getting bigger, as per the data collected for past few years.
The study gives a respite by revealing that the ozone layer is showing early signs of thickening. The recovery process has started after years of depletion. But it will take 10 years before the ozone hole starts reducing in size significantly.
Researchers have given credit for this recovery to political determination to completely eliminate the man-made chlorofluorocarbons. The CFCs are the main source of destruction of ozone layer.
"International action on the ozone layer is a major environmental success story... This should encourage us to display the same level of urgency and unity to tackle the even greater challenge of tackling climate change", stated WMO Secretary-General Michel Jarraud.
Researchers do not exactly know when the hole will heal itself. The WMO shared that ozone should be at its 1980 level by mid-century or little later than that. More improvements can be made if ozone-depletion substances are completely eradicated.
Prof. David Vaughan from the British Antarctic Survey (BAS) stated that his organization is carrying out a detailed research. Once the data from the Antarctic comes, they will be able to throw light on the WMO's findings. If the findings turn out to be true, then it definitely underlines the potential power of international agreement.
Dr. Ken Jucks from NASA said that finally, humans have started moving on the right path from where atmosphere can be converted back to the level where it was before the industrial revolution started.
The good news came along with a bad one that atmospheric green house gases are increasing climate change. The WMO affirmed that these gases have reached a record high. Researchers said that it is not easy to handle a gas like carbon dioxide as it is involved in many activities carried out by humans.
