Extraordinarily cold temperatures in the stratosphere during the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far, according to a study by climate researchers at KIT (Karlsruhe Institute of Technology). These chemical conversion products attack the ozone layer and destroy it partly.
