When the Antarctic ozone hole breaks up each year, the ozone-depleted air drifts into nearby regions. Decreases in the ozone level of up to 10 percent have been reported in New Zealand in the month following the breakup of the Antarctic ozone hole, [186] with ultraviolet-B radiation intensities increasing by more than 15 percent since the 1970s.
Ozone depletion is not a primary cause of climate change, however there exists a physical science connection between the two phenomena. The Earth's atmospheric ozone has two major effects on the Earth's temperature balance. Firstly, it absorbs solar ultraviolet radiation, leading to the heating of the stratosphere.
Ozone remains depleted in the midlatitudes of both hemispheres. The global-average total column ozone amount for the period 1997-2001 was approximately 3% below the pre-1980 average values. Models capture the observed long-term ozone changes in northern and southern midlatitudes.

The ozone layer is on track to fully recover from its depletion within the next four decades, a panel of scientists gathered by the United Nations said on Monday. U.N.: Depletion of ozone layer ...
Tropospheric ozone depletion events are phenomena that reduce the concentration of ozone in the earth's troposphere. Ozone (O3) is a trace gas which has been of concern because of its unique dual role in different layers of the lower atmosphere. [1] Apart from absorbing UV-B radiation and converting solar energy into heat in the stratosphere ...
