Question: How big is the hole in the ozone layer?
Answer: First formed in the 1970s, the ozone hole can be as big as the U.S. and as deep as a 66% loss of ozone. However, less-well-known is that ozone depletion has been measured everywhere outside the tropics, and that it is, in fact, getting worse. |

Ozone levels vary by season and latitude. In the middle latitudes (most of the populated world), ozone levels have fallen about 10% during the winter and 8% in the summer. Since 1979, they have fallen about 4% per decade when averaged over the entire year. Depletion is generally worse at higher latitudes, i.e. further from the Equator.
