Four new man- made ozone destroying gases have been identified. Researchers from the University of East Anglia discovered that three CFCs and a HCFC are contributing to the destruction of the ozone layer.
It has long been known that gases such as CFCs can cause damage to the ozone layer. In 2010 a global ban on the production of previously known harmful CFCs was finally implemented. The recent discovery of further, similar substances, is therefore not only worrying but also frustrating for Scientists.
The research shows that the four gases in question where first present in our atmosphere in the late 1960s, which suggests they are probably man-made. Currently however their source remains unknown. The research indicates that two of the four gases are accumulating at a worrying rate, it is therefore key that further studies determine where they are being emitted from.
