According to the UN World Meteorological Organization (WMO), the phenomenon was driven by ozone-depleting substances in the atmosphere and a very cold winter in the stratosphere. The two factors combined to give a very high level of depletion.
“It’s now back to normal again…the ozone hole has closed,” said WMO.
