A study conducted shows that the rate of the ozone layer repair in slowing done. The reason behind the slowing repair rate is a generation of the large hole in the ozone.
The study detects that a country somewhere in the Eastern parts of the Asian continent has breached the regulations laid down for the control of the CFC’s. The CFC’s are the sole contributors to ozone layer depletion.
Mauna Loa Observatory of Hawaii points out to a nation in the Asian continent to be the source of the CFC production.
‘We show that the rate of decline of atmospheric CFC-11 was constant from 2002 to 2012, and then slowed by about 50 percent after 2012. This evidence strongly suggests increased CFC-11 emissions from eastern Asia after 2012,’ says an international team of the researchers involved in the study.
It is the ozone layer that protects flora and fauna of the Blue Planet from the deadly effects of the harmful ultraviolet radiations.
The Montreal Protocol of 1987 banned the use of the industrial aerosols. The significant content of the aerosols was the chlorofluorocarbons (CFC’s). These aerosols are responsible for the chemical dissolution of the ozone layer. The significant effect of the ozone chemical dissolution was witnessed over Antarctica.
‘The hole in the Ozone’ over the Southern pole is indicative of the fact that the ozone is healing. Meanwhile, Joanna Haigh conveys, ‘Perhaps even more serious is the role of CFCs as long-lived greenhouse gases.’ Joanna Haigh is a professor at the Imperial College in London.
Around two decades ago, the CFC’s were responsible for causing about ten percent of the global warming. This ten percent accounts for the human-induced global warming.
CFC’s were a part of the aerosol sprays in the form of the propellants. They were also used in the refrigeration and the air conditioning systems. It was way back in the 1970’s and 1980’s. Officially, the CFC’s do not exist today.
The study infers, ‘This is the first time that emissions of one of the three most abundant, long-lived CFCs have increased for a sustained period since production controls took effect in the 1980s.’
