Anthropogenic emissions of chlorofluorocarbons (CFCs) have caused the Antarctic ozone hole during austral spring. CCMI provides information on the recovery of the ozone layer and potential interactions with climate change.
Emissions from anthropogenic activities such as transport and energy generation contribute to both climate change and air pollution. CCMI investigates potential feedbacks between these environmental issues.
The lifetimes and spatial distributions of many greenhouse gases are controlled by atmospheric chemistry and transport. CCMI studies how the impact of climate forcing agents will change over time.
