Important issues in the assessment
Preface WMO O3 Assessment 2006:
 ozone recovery expected from
leveling off of stratospheric chlorine
(Montreal Protocol and
ammendments), but role of
stratospheric bromine/shortlived
substances may become more
important
 How does climate change affect the
ozone layer (Antarctic ozone hole
anomaly in 2002? changes in
atmpospheric transport and
chemistry?)
