The ozone hole over Antarctica, which fluctuates in response to temperature and sunlight, grew to the size of North America in a one-day maximum in September that was the fifth largest on record, since NOAA satellite records began in 1979. NOAA scientists, who have monitored the ozone layer since 1962, have determined that this year's ozone hole has passed its seasonal peak for 2008. more...11.13.2008
