The Antarctic hole

Year: 2007
From collection: Vital Ozone Graphics
Author: Emmanuelle Bournay, UNEP/GRID-Arendal
Despite progress achieved under the Montreal Protocol, the ozone “hole” over the Antarctic was larger than ever in September 2006. This was due to particularly cold temperatures in the stratosphere, but also to the chemical stability of ozone-depleting substances – it takes about 40 years for them to break down.
