Ozone hole over Arctic hits record
The ozone layer that protects life from the sun’s ultraviolet radiation has thinned to record low levels over the Arctic, the UN says.
The atmosphere over the Arctic lost 40 per cent of its ozone between the beginning of winter and late March, the World Meteorological Organization, or WMO, reported Tuesday. The organization is the UN’s weather agency, and its report was based on ozone measurements around the Arctic from satellites, balloons and ground stations.
The previous record was a loss of 30 per cent over the whole winter.
