Increased polar stratospheric ozone losses and delayed eventual recovery owing to increasing greenhouse-gas concentrations.

Presents research which studied the interplay between projected future emissions of greenhouse gases and levels of ozone-depleting halogen species. Chemical reactions responsible for ozone depletion; Impact of greenhouse gases; Use of a global climate model with ozone-depletion chemistry; Results; Arctic losses of ozone; Predicted increase in severity and duration of the Antarctic ozone hole.
