For the first time, a single model has combined greenhouse warming and ozone depletion in a long-term simulation, and the results are sobering: Greenhouse gases and chlorofluorocarbons together may be ganging up to destroy ozone. In the wake of global controls on ozone-destroying compounds, most observers expected that the annual Antarctic ozone hole would fade, and the more modest Arctic ozone losses diminish, as atmospheric chlorine declines. But in this week's issue of Nature, a group from NASA's Goddard Institute for Space Studies in New York City reports that their model indicates that during the next few decades, greenhouse gases will trigger a springtime ozone hole over the Arctic, much like the one now over the Antarctic.
