Yes, what's up! Here we go. Climate change and ozone depletion affect one another in complicated ways. In simple terms, "the ozone hole" pertains to the Southern Hemisphere. However, reductions in ozone content in the stratosphere above the Arctic have been recorded during the northern winter untill early spring (January through March) in recent years. These reductions, about 20-25%, are much smaller than those measured in each southern spring (September through December) over the Antarctic ozone hole, the big one.
