KEY POINTS
· The ozone hole over the Antarctic has been the smallest observed since 1982, NASA and US National Oceanic and Atmospheric Administration (NOAA) scientists have reported.
· The annual ozone hole reached its peak extent of 16. 4 million sq km and then shrank to less than 10 million sq km NASA has described it as great news for the Southern Hemisphere.
· Manufactured chemicals deplete the ozone layer. Each spring over Antarctica (it is now spring there), atmospheric ozone is destroyed by chemical processes.
· This creates the ozone hole, which occurs because of special meteorological and chemical conditions that exist in that region.
Why it is small this year?
· There have been abnormal weather patterns in the atmosphere over Antarctica.
· In warmer temperatures like this year, fewer polar stratospheric clouds form and they don’t persist as long, limiting the ozone-depletion process.
· While it is good news, NASA has cautioned it is important to recognise that what we are seeing this year is not a sign that atmospheric ozone is suddenly on a fast track to recovery.
Utility of Montreal protocol
· The research findings is an alert to nations to protect the shrinking ozone hole for welfare of the people.
· Since its legally binding agreement developed countries has to help other countries via green investment to reduce the destruction of ozone layer.
· Parties which violate the agreement should be criticized appropriately irrespective their status at global level.
· This also needs to be linked with Kigali agreement 2016 and phasing out of pollutants should be done gradually at national levels.
· Countries must cooperate with each other by utilizing Montreal protocol as a platform to protect the depletion of ozone layer.
