The hole in Ozone layer has shrunk thanks to the ban of CFCs, Nasa has confirmed, after finding that chlorine levels are rapidly declining in Earth’s stratosphere.
Ozone layer on the mend, thanks to chemical ban By Eric Hand Jun. 30, 2016 , 2:00 PM Since it was discovered in 1985, the Antarctic ozone hole has been a potent symbol of humankind’s ability to
NASA has claimed that an international ban on chemical usage can help and save Ozone to recover. It said that an international ban on chlorine-containing man-made chemicals called chlorofluorocarbons (CFCs), has resulted in about 20 per cent less ozone depletion.
For the first time, direct observations of the Antarctic ozone hole show evidence of recovery due to the 1987 Montreal Protocol’s ban on a class of potent, ozone-depleting chemicals.
Paul Newman, chief earth scientist at NASA’s Goddard Space Flight Centre: «It’s really good news. «If ozone-depleting substances had continued to increase, we would have seen huge effects.
Satellite data shows that the Earth’s ozone layer is recovering — and scientists say it’s a direct result of a decades old international chemicals ban. The findings were published Thursday in the
The ozone layer is HEALING: Hole over Antarctica is closing thanks to a worldwide ban on the damaging chemicals, NASA confirms. Ozone layer over the Antarctic is starting to recover from chemical
WASHINGTON: An international ban on chlorine-containing man-made chemicals called chlorofluorocarbons (CFCs), has resulted in about 20 per cent less ozone depletion, NASA said.
NASA has confirmed that the ozone hole above the Antarctic is starting to close up ever since the ban was imposed through the 1987 Montreal Protocol. Data from NASA’s Aura satellite showed the success of the ban, with 20 percent less depletion of the ozone layer since 2005.

A hole in the ozone layer that appeared above Antarctica in the 1980s has shrunk thanks to a worldwide ban on damaging chemicals, the United States Aeronautic Space Agency (NASA) has confirmed.
The ozone layer in the lower stratosphere remains dangerously thin in mid-latitude areas. This could be due to chemicals left unchecked.
