The Ozone hole: What a crock
The NASA graphic above shows that the ozone hole has just fluctuated for the last 20 years. There is no clear direction of change. So the ban on CFCs has clearly not had the intended effect.
And we see another fallacy below: Taking one year as the measure of a trend:
The sustained damage to the ozone layer had been caused by aerosol spray cans and refrigerators emitting chlorofluorocarbons (CFCs). In 1987, the United Nations responded, banning the manufacture and use of CFCs and other substances under the Montreal Protocol. Since then, the hole in the ozone layer has been shrinking.
In autumn 2010, scientists reported the first success, saying the ozone layer had begun to heal. Now a new study shows for the first time that the healing of the ozone layer is also actually improving the health situation for people. Carcinogenic UV rays on the ground have also been diminishing in recent years, researchers led by Christos Zerefos at the Research Centers for Atmospheric Physics and Climatology at the Academy of Athens in Greece conclude in their study, published by the scientific publication Atmospheric Chemistry and Physics.
"The results are encouraging," said Markus Rex, a respected ozone expert at Germany's Alfred Wegener Institute for Polar and Marine Research in Potsdam. The fact that the ozone layer in the regions researched has become thicker is a result of the successful Montreal Protocol, he added.
