But, in the Northern Hemisphere, the main cause appears to be black carbon […]

Dramatic Loss of Arctic Ozone

The European Space Agency, the UN’S World Meteorological Organization, and the Alfred Wegener Institute for Polar and Marine Research are among the leading authorities reporting a record depletion of the ozone layer over the Arctic.

According to the WMO, “depletion of the ozone layer … has reached an unprecedented level over the Arctic this spring because of the continuing presence of ozone-depleting substances…”
