What is the Ozone Layer and what does it do actually?
The ozone layer is a high concentration of ozone molecules and shields earth from the harmful effects of UV rays (Ultraviolet Radiation): UV rays can even cause skin cancer. If due to some reason ozone layer is destroyed then it’s impossible for a living organism to survive on this planet.
The chlorofluorocarbons (CFCs) are man-made chemicals which cause huge damage to the ozone layer and, therefore, the Montreal Protocol, a global agreement to protect the ozone layer, was adopted to ban it.
Ozone Layer repairing by itself
Antara Banerjee is the lead author of the study about the ozone layer. She also works at the National Oceanic and Atmospheric Administration (NOAA).
“We found climate changes in the southern hemisphere within the air circulation patterns”, she told The Independent.
The air circulation patterns are showing signs of change after the implementation of Montreal Protocol and that might be because the ozone layer is healing.
The CFCs, the compounds which are responsible for ozone damages, from spray cans and refrigerants have declined since the Montreal Protocol was agreed.
Antara Banerjee further added that the international treaty showed it worked and now the damage is reversing and that is very good news for the fight against climate change.
