Scientist report dramatic ozone damage

Worrying data has emerged, as scientists have discovered that the ozone loss over the arctic was so dramatic this year that it would be fair to now call it an actual “ozone hole”.

Measured 20km (13 miles) above ground, as much as 80 percent of the ozone layer was lost. An uncharacteristically long spell of cold weather at altitude triggered the depletion, as the chlorine chemicals that destroy ozone thrive in cold conditions.
