The Antarctic hole
Year:
2008
Author:
Emmanuelle Bournay, UNEP/GRID-Arendal
Description:
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.
