The 12 pages that link to Ozone hole, each with the reason it gives.

• Montreal ProtocolBroader topic: Its dramatic growth helped spur international action on ozone-depleting chemicals.

• OzoneBroader topic: It is the clearest large-scale episode of stratospheric ozone depletion.

• Ozone depletionBroader topic: It is the clearest regional expression of rapid halogen-driven depletion.

• ChlorofluorocarbonBroader topic: CFC-derived chlorine drives the pronounced springtime ozone loss over Antarctica.

• HydrofluorocarbonRelated: Concern over ozone loss drove the transition away from CFC refrigerants.

• Ozone–oxygen cycleBroader topic: Its formation reveals how chlorine chemistry can accelerate ozone destruction beyond the basic cycle.

• HydrochlorofluorocarbonRelated: The discovery heightened the urgency of controlling ozone-depleting chemicals, including HCFCs.

• Ozone-depleting substanceRelated: Its discovery provided striking evidence of the damage caused by ozone-depleting chemicals.

• Polar vortexRelated: The isolated, cold Antarctic vortex helps create conditions for rapid springtime ozone loss.

• Polar stratospheric cloudBroader topic: Cloud-driven chlorine activation contributes to the rapid springtime ozone loss it describes.

• 1,1,1-TrichloroethaneRelated: Scientific evidence of ozone loss helped build support for controlling ozone-depleting chemicals.

• TrichlorofluoromethaneBroader topic: CFC-11 contributed chlorine to the chemistry responsible for severe Antarctic ozone loss.
