 Key ongoing issues
• Quantitative relationships between change in ozone
change, and change in UV radiation as it affects
humans and ecosystems
• Balance of contrasting effects, within organisms (e.g.
positive and negative effects of UV on human health),
and ecosystems.
 What is new in science
• Improved understanding of the fundamental
mechanisms of responses.
• Interactions with other elements of environmental
change
 Key requests from the Parties to the Protocol
