Just over 30 years ago, scientists discovered an environmental crisis so terrifying it shocked the world into action. The image of the ozone hole over Antarctica – a widening rip in the very fabric of Earth’s sun-shielding stratosphere – was a symbol of destruction so obvious even politician...
Why does a ozone hole form over Antarctica? The ozone hole is caused by the effect of pollutants in the atmosphere destroying stratospheric ozone.During the Antarctic winter something special happens to the Antarctic weather. Firstly, strong circular winds form that blow around the whole continent,...
