Meteorologists and atmospheric chemists have watched in alarm as a similarly explosive mixture to the Antarctic vortex has been assembled in the Arctic For the first time, scientists have detected a ?hole? in the ozone layer over the Arctic and northern Europe. Ozone, a form of oxygen, acts as a high-altitude atmospheric screen against cancer-causing ultraviolet light. But at some altitudes this spring, levels have been 50 per cent below any previously observed.
