Bad news for ozone layer

Scientists at the Max-Plank Institute in Mainz, Germany, have identified another culprit in ozone destruction. Removal of active nitrogen from the gas phase through aerosol-particle sedimentation (denitrification) can substantially increase ozone losses. A Waibel and his team have shown that this loss is particularly significant in the Arctic, where future stratospheric cooling may enhance denitrification and ozone losses .
