In the Southern Hemisphere, depletion of stratospheric ozone has previously been shown to be the cause of tropical expansion. 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…”
