Antarctic Ozone Hole Now Among Biggest on Record

El Nino a suspect as cold expands Antarctic ozone hole: U.N. weather body, Japan Times, October 30, 2015,
GENEVA – The Antarctic ozone hole has swelled this month to one of its biggest sizes on record, U.N. and U.S. scientists say, insisting that the Earth-shielding ozone layer remains on track to long-term recovery but residents of the Southern Hemisphere should be on watch for high UV levels in the weeks ahead.

The World Meteorological Organization, in a regular bulletin released Thursday, said the Antarctic ozone hole often faces seasonal and year-to-year variations, but says the expansion this year shows “we need to remain vigilant.”
