The Antarctic springtime ozone hole is one of the most dramatic manifestations of global change.

In 2004, the size of the ozone hole was smaller than the average over the past decade, although the total amount of ozone destroyed, which relates to the size, depth and persistence of the ozone hole, was estimated to be much higher than most years in the past decade.

That year, a large hole in the ozone layer over the Antarctic was detected, prompting Vienna Convention parties quickly to negotiate a graduated phase out of ozone depleting substances under the Montreal Protocol.

In the U.S., chlorofluorocarbons continued to be used in other applications, such as refrigeration and industrial cleaning, until after the discovery of the Antarctic ozone hole in 1985.

In that regard it should be noted that annual variations in the depth, size and persistence of the ozone hole depend significantly on changing meteorological conditions in the stratosphere.

Ozone depletion

Get in that hole.

And there was an hole in the midst of the robe, as the hole of an habergeon, with a band round about the hole, that it should not rend.

Look at this hole in the middle. That hole was caused by a micrometeorite hitting the Moon.

It is a black hole.

In addition to the above noted activities, scientific and other research related activities that were reported on included studies on ozone variation, temperature influences on ozone, the interaction between ozone and climate and climactic profiles of ozone.

illegal trade in ozone depleting substances

Illegal trade in ozone depleting substances is controlled by the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, which aims to gradually reduce and finally phase out all ozone depleting substances.

Those Parties who celebrated Ozone Day this year are to be commended and all Parties are urged to consider celebrating Ozone Day as a way of promoting awareness both of the ozone regime and of the continuing need for vigilance in our efforts to protect the ozone layer.

Ozone Day celebration As noted above, the Secretariat helped celebrate Ozone Day in 2005 in Vienna, through the conduct of a seminar on the ozone regime and the reception hosted by the Government of Austria.

All of these ozone depleting substances contain either chlorine or bromine (substances containing only fluorine do not harm the ozone layer).
