GZEcoDictionary: ozone again

September 4th, 2013

Hello GreenZoners,

last “EcoDictionary” post was about ozone and ozone layer. Today one word more connected with this topic.


Ozone hole is an annual thinning of the ozone layer over Antarctica, caused by stratospheric chlorine. The cause of the ozone hole is probably CFC (Chlorofluorocarbon) compounds which break down (due to ultraviolet light) and become free radicals containing chlorine high in the Earth’s atmosphere.

Why “probably”?

There is a lot of different opinions about ozone hole: causes and effects. According to some scientists ozone hole is very dangerous, for others it is totally safe. Who is right, who is wrong? Not sure.

However – good news: in 2012 it has been reported that the ozone hole had decreased to the smallest size since 2002.
