    Chemistry Ozone Depletion Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as theozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polartropospheric ozone depletion events. The
