Every September and October, a "hole" of varying size emerges in Earth's ozone layer over Antarctica, an effect of a buildup of ozone-depleting human-made chemicals high in the atmosphere. Now that levels of these chemicals are declining as a result of international agreements put in place decades ago, scientists predict that the annual ozone hole is poised to begin a shrinking trend.
