Ozone Changes
The hole in stratospheric ozone that develops over Antarctica as the frozen continent emerges from winter is now acting in ways never before observed.
Scientists at Europe’s Copernicus Atmosphere Monitoring Service say the hole is not only about half as large as normally seen in September, but it has been off-center and far from the South Pole.
They point to a sudden and significant warming of the stratosphere over Antarctica during the month. This appears to have destabilized the process in which ozone has been destroyed since the now-banned chlorofluorocarbons began causing the ozone hole during the 1960s and 1970s.
