Arctic Ozone Loss at Record Level: Science in the News
Arctic Ozone Loss at Record Level from BBC News Online Ozone loss over the Arctic this year was so severe that for the first time it could be called an “ozone hole” like the Antarctic one, scientists report. About 13 miles above the ground, 80% of the ozone was lost, they say. The cause was an unusually long spell of cold weather at altitude. In cold conditions, the chlorine chemicals that destroy ozone are at their most active. It is currently impossible to predict if such losses will occur again, the team writes in the journal Nature. http://ow.ly/6MPRt “Science in the News” is produced daily by Sigma Xi as a service for its members and the public.
