Ozone layer or Ozone shield is the area of Earth’s stratosphere which absorbs most of the Sun’s harmful UV radiations. Since the 1970s, the Ozone layer was started depleting gradually and in the past century, it has suffered a lot of damage. The world has undergone a severe climate change since the hole in the Ozone layer.
A recent report provided by the UN says that the Ozone layer is finally healing. This is a good sign to predict a better environment for future generations. This healing started because of the cut down of the toxic chemicals and gases that were depleting the layer. A recent research predicted that the Ozone layer above the Northern Hemisphere would completely heal in the 2030s and the Antarctic Ozone hole would heal in 2060s.
The report co-chairman Paul Newman, the chief Earth scientist at NASA’s Goddard Space Flight Center said, “If ozone-depleting substances had continued to increase, we would have seen huge effects. We stopped that.”
The report provides a ray of hope, less than a month after the IPCC, or Intergovernmental Panel on Climate Change (IPCC), released a watershed report which described the devastating effects of a 2°C temperature rise compared to pre-industrial levels, described by UN chief António Guterres as an “ear-splitting wake-up call.” The UN Chief called this healing as “pivotal time for climate action”.
